I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter. How old am I now?
Answers
Answer:
65 years old.
Step-by-step explanation:
Define the variables:
Let x be the age of the granddaughter.Let y be the age of the grandparent.Given:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Create two equations with the given information and defined variables:
\(\begin{cases}y = 13x\\y + 1 = 11(x + 1)\end{cases}\)
Substitute the first equation into the second equation and solve for x:
\(\implies 13x+1=11(x+1)\)
\(\implies 13x+1=11x+11\)
\(\implies 2x=10\)
\(\implies x=5\)
Substitute the found value of x into the first equation and solve for y:
\(\implies y=13(5)\)
\(\implies y=65\)
Therefore, the age of the grandparent now is 65 years.
Given statements:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Let us represent the character's age by variables. Assuming that the grandparent's age is G and the granddaughter's age is D. Now, using the obtained variables and the statements, create two equations that represents the provided statements. Then, we can compare the equations and simplify if needed to determine the value of the variables.
\(\implies \left[\begin{array}{ccc} \text{G = 13D} \\ \text{G + 1 = 11(D + 1)}\\\end{array}\right]\)
Since G = 13D is in the form of direct variation, we can substitute the value of G into the second equation to determine the value of D (the age of the granddaughter). Then, we can substitute the value of D into any of the two equations to determine the age of the grandparent.
⇒ G + 1 = 11(D + 1)⇒ G + 1 = 11(D + 1) [G = 13D]⇒ 13D + 1 = 11(D + 1)To solve for D, simplify both sides of the equation by using the distributive property. We need to simplify both sides of the equation so that we can isolate the variables on the other side of the equation.
⇒ 13D + 1 = 11(D + 1)⇒ 13D + 1 = 11D + 11Isolate the variables on one side. This step is necessary because it can cancel out the extra variable and simplify the other variable. To do this, you can either add or subtract on both sides of the equation.
Note: I am subtracting 11D on both sides of the equation since it is my preference. But you can also subtract 13D on both sides of the equation.
⇒ 13D + 1 - 11D = 11D + 11 - 11D⇒ 1 + 2D = 11To further isolate 2D, we need to subtract 1 on both sides of the equation to cancel out the 1 on the left-hand side of the equation. Then, we have:
⇒ 1 + 2D - 1 = 11 - 1⇒ 2D = 10But the variable is still not completely isolated since there is a coefficient being multiplied to D. To isolate the coefficient from the variable, we will need to divide the coefficient (2) on both sides of the equation.
⇒ 2D = 10⇒ 2D/2 = 10/2Then, simplify both sides of the equation. Eventually, we will have a variable on one side and a numerical value on the other side.
⇒ 2D/2 = 10/2⇒ D = 5Now we know the age of the granddaughter, we can substitute the age of the granddaughter into one of the equations and simplify it to determine the age of the grandparent. I am going to choose G = 13D since it is easier to simplify. Then, we will substitute the value of D into the equation.
⇒ G = 13D ⇒ G = 13(5)⇒ G = 65 yearsTherefore, the age of the grandparent is 65 years.

PLEASE ANSWER THIS: Andrea had $20. She bought 4 paper pads at $1.19 each, 3 notebooks at $1.89 each, and also a book at $4.95. Now she wants to use the remaining money to buy as many 79-cent pens as possible. How many pens could she buy?
Answers
Answer:
5 pens
Step-by-step explanation:
Currently she has spent:
4(1.19) + 3(1.89) + 4.95 = 15.38
She has this amount left:
$20 - 15.38 = 4.62
So if she wanted to buy as many pens with the $4.62:
4.62/0.78 = 5.84
But you can't buy .84 of a pen, so she can buy 5 pens
Answer: 5 pens
Step-by-step explanation:
FACTS:
andrea has $20.
She bought:
4 paper pads for $1.19 each
3 notebooks for $1.89 each
1 book for $4.95
Will use the remaining money to buy pens that cost 79 cents ($0.79) each.
How many pens can she buy?
Step 1: Find how much she spent on the paper pads
1.19x4= 4.76
Ans= $4.76
Step 2: Find how much she spent on notebooks
3x1.89=$5.67
Ans= $5.67
Step 3: Find how much she has spent so far.
4.76 + 5.67 +4.95= $15.38
Step 4; Find how much she has left.
20-15.38= 4.62
Step 5: Find the number of pens she can buy.
She has $4.62 to buy pens that cost $0.79 (79 cents) each. how many pens can she buy?
To solve this, divide 4.62÷0.79. the decimal makes no difference in what operation you do.
4.62÷0.79= 5.84810126582 which rounds to 5.8 which rounds to 6.
Step 6: Check
REMEMBER:
pens cost $0.79 each
we're assuming she got 6 pens
in order for 6 to be correct, 6x0.79 MUST equal 4.62 or less because that's how money she had to spend on pens.
0.79x6= 4.74. It's wrong. In this case, it's always the number that comes before it, in this case 5.
Even though 5x0.79= 3.95 which is less than 4.62, it must be correct because it makes so much more sense to have some money left than spend more than what you even have. In questions like this, don't always rely on rounding.
Answer= 5 pens
Match the volume of the cube to the length of each edge.
Answers
Answer: 7
Step-by-step explanation:
If volume is equal to length to width to height, then 343 = l x w x h. Since the shape is a cube, all the sides are equal so length width and height are equal. Thus, they can all be represented by x. So 343 = x to the third power. You can then take 343 to the third root and get 7. Also, if I counted correctly, each individual unit cube on the length width and height are seven. So length is 7 width is 7 height is 7 and 343 to the third root is 7.

If a value of 80.8° is added to the data, how does the range change?
Answers
Answer:
The original data set would be:
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
So to find the range you would do:
105 - 57 which equals 48.
So the range for the original data set would be 48.
The new data set adding 80.8:
57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105
So to find the range for the new data set you would do:
105 - 57 which would still equal 48.
So the range for the new data set would be 48.
The range for the original and new data set stayed the same.
Step-by-step explanation:
You're welcome.
Step 2: find the range
105 - 57 = 48
The range for the original data set is 48.
The new data set is adding 80.8
Step 1: find the new data set.
57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105
Step 2: find the range
105 - 57 = 48.
The range is still the same for the original and new data set.

X= -4 Y= -10
X= 0 Y=-4
X=4 Y=0
X=8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that
X=-4 Y= -5
X=0 Y= -2
X=4 Y=1
X= 8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= -2
Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.
Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2
X=-8 Y= 0
X= -4 Y = 1
X=0 Y=2
X=4 Y=3
X=8 Y=4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Do this method for 9
y = 2x -3 so whatever x is, y is 2 times that -3
y=2x +1 so whatever x is y is 2 times that +1
y= 2x so whatever x is y is 2 times that
Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them
Make sure to label each line

What is the total surface area of the figure?
Answers
Answer:
531 in²
Step-by-step explanation:
5 faces of the cube are facing the surface because the top one is shared with the triangular prism.
Surface area of a cube is S = 5 × (9)²
S = 405 in²
Now the triangular prism: S = (1/2)lP + B, where l is slant height and p is the perimeter of the base. (ignore B base area because this is also not facing the surface/shared with the cube).
S = (1/2)7×(4×9)
S = 126 in²
Add 126 + 405 to get 531 in²

An isosceles triangle has 2 sides that are equal.
I plotted these points. See attached screenshot.
The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.
The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.
These two sides make a right triangle and are equal length. This is an isosceles right triangle.
A pharmacist put 4.536 ounces of vitamin pills into bottles. She put .042 ounce of vitamin pills into each bottle.
How many bottles did the pharmacist use for these vitamin pills?
Answers
Answer:
108 bottles
Step-by-step explanation:
the total is 4.536 oz of vitamin pills
each bottle can accomodate 0.042 oz of vitamin pills
to know the quantity of each bottle
we calculate
0.042 oz of vitamin pills = 1 bottle
4.536 oz of vitamin pills = (4.536 x 1)/0.042=108
so therefore 4.536 oz of vitamin pills will accommodate 108 bottles

Step-by-step explanation:
The current probability of picking a red ball is \(\frac{x}{15}\). When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:
\(\frac{x+5}{15+5} = \frac{3}{4}\)

60 = 4x + 20
40 = 4x
x = 10 red balls
