Lenard is saving money to buy a computer. He saves $58.25 per week. Write the meaning of each product. Use numbers in the fill in the blank items.
1. The product of 58.25(4) means Lenard will have an additional $ _____ saved _____ weeks (from now/ago).
2. The product of 58.25(–3) means Lenard had $ _____ (more/less) _____ weeks ago.
Answers
1. The product of 58.25(4) means Lenard will have an additional $233 saved 4 weeks from now.
2. The product of 58.25(–3) means Lenard had $174.75 less 3 weeks ago.
The concept of saving $58.25 per week was adopted by Lenard.
On this note, after every week, Lenard will have $58.25 more than she had the previous week.
In essence, every week from now adds up $58.25 to Lenard's balance and every week ago takes off $58.25 from his current balance.

A group of 24 students spent 1,296 minutes studying for an upcoming test. What prediction can you make about the time it will take 150 students to study for the test?
It will take them 174 minutes.
It will take them 2,592 minutes.
It will take them 8,100 minutes.
It will take them 8,745 minutes.
Answers
Answer:
It will take them 8,100 minutes.
Step-by-step explanation:
If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)
150 x 54 minutes = 8,100 minutes.
It will take them 8,100 minutes.

The volume of a cone is 80π cubic units. The radius of this cone is tripled.
Eric says the new volume will be tripled. It is 240π cubic units.
Natalie says the new volume will be multiplied by 9. It is 720π cubic units.
Who is correct? Explain your reasoning.
Answers
V = (1/3)πr^2h
Where V is the volume, r is the radius, and h is the height. If the radius of a cone is tripled, the volume of the cone will be multiplied by 9. This is because the radius is squared in the formula, so tripling the radius is the same as multiplying it by 3*3=9.
To see this more clearly, consider the following example:
Suppose the radius of a cone is 2 units and the height is 4 units. The volume of the cone is:
V = (1/3)π(2^2)(4) = (1/3)π(4)(4) = (1/3)π(16) = 16π/3 cubic units
If we triple the radius of the cone to 6 units, the volume of the cone becomes:
V = (1/3)π(6^2)(4) = (1/3)π(36)(4) = (1/3)π(144) = 144π/3 cubic units
The volume of the cone has been multiplied by 9.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Answer:
\(\huge\boxed{\sf x =28 \textdegree}\)
Step-by-step explanation:
Given that,
∠IAK = 62°
∠IAK + ∠IAD = 90° (Complementary angles)
62 + ∠IAD = 90°
Subtract 62 to both sides
∠IAD = 90 - 62
∠IAD = 28°∠IAD = ∠ACB (Corresponding angles are equal)
So,
∠ACB = 28°∠ACB = ∠GCJ (Vertically opposite angles are equal)
So,
28° = x°
OR
x° = 28°\(\rule[225]{225}{2}\)
Answer:
28 degrees
Step-by-step explanation:
If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.
--> Angle LAJ is 62 degrees
If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.
We know that in a triangle, there are three angles, and the angle measures combined equals 180.
Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.
--> 180 - 90 - 62 = 28
--> Angle BCA = 28 degrees
Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.
Angle x = 28 degrees

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.
