When we're solving with scale factors, we either divide or multiply.
If the shape becomes larger, we multiply to get the new length.
If the shape becomes smaller, we divide to get the new length.
Solving the QuestionWe're given:
Original side length is 2.5 unitsScale factor = 6Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.
2.5 x 6 = 15
Therefore, the missing side length is 15 units.

The United States Postal Service delivers about 2^8 ⋅ 5^2 pieces of mail each second. There are 2^8⋅3^4⋅5^2 seconds in 6 days. How many pieces of mail does the United States Postal Service deliver in 6 days? Write your answer as an expression involving three powers.
Key: ^ means the number that comes after is an exponent. For example: 4^9, 4 is the base and 9 is the exponent.
Answer:
The total number of pieces delivered in 6 days is the number delivered each second (28.52) times the number of seconds in 6 days (28 34.52). This gives:
(28.52) (28 3¹.52) 28 + 8.31.52+2 = 216.31.54

Determine which set of side measurements could be used to form a right triangle.
9, 11, 13
6, 12, 17
square root of 8, 5, square root of 17
square root of 2, square root of 7, 9
The set of side measurements that could be used to form a right triangle is √8, 5, and √17 option (C) is correct.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
It is given that:
The side length of the triangle is shown in the option:
As we know,
Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.
Using Pythagoras' theorem:
From option(C):
√8, 5, and √17
(√8)² + (√17)² = 5²
8 + 17 = 25 (True)
Thus, the set of side measurements that could be used to form a right triangle is √8, 5, and √17 option (C) is correct.

Jose substitutes a value for y in the equation 5y = 3y + 4
How will Jose know if the value is a solution of the equation?
Answer:
Step-by-step explanation:
Equation
5y = 3y + 4
combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.
-3y + 5y = 4
After adding a low negative to a high positive number. Turns into 2y.
2y = 4
Divide 2 on both sides to remove the number from the variable on the left.
\(\frac{2}{2}\)y = \(\frac{4}{2}\)
2 is canceled on the left side which gives the solution for Y.
y = 2

Step-by-step explanation:
The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?
160 ml
400 ml
1,600 ml
4,000 ml
Answer: 1,600 ml
Step-by-step explanation:
You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).
2,800 ml - 1,200 ml = 1,600 ml
I hope this helps :)
Answer: 1,600 mL
Step-by-step explanation:
1. convert the 1,200 mL to L, which is 1.2 L.
2. Subtract that value from 2.8 L, equaling 1.6 L
3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.
Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.
Answer:
x = 11(13/14)
Step-by-step explanation:
3/5(x – 7/10) = -31/4
open the bracket:
3/5 * x – 7/10 = -31/4
3/5 * –7x/10 = -31/4
3/5 + 31/4 = 7x/10
(12+155)/20 = 7x/10
167/20 = 7x/10
cross multiply:
140x = 1670
x =1670/140
x = 11(130/140)
x = 11(13/14)
The value of x is 1/5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3/5 (x − 7/10)= −3 1/4
Now, Solving for x
3/5 ( x- 7/10 )= 13/4
x- 7/10 = -13/4 x 5/3
x- 7/10 = -65 /12
x= -65/12 + 7/10
x= 24/ 120
x= 1/5
hence, the value of x is 1/5.

Which best explains why the slope of the line between points A and D is the same as the slope between points A and B?
Answer: Which best explains why the slope of the line between points A and D is the same as the slope between points A and B? Points A, D, and B are on the hypotenuses of similar triangles. Therefore, AD = AB, so the slope of AD is the same as the slope of AB.

the volleyball team needs new uniforms. the students plan to sell plush toy Eagles ( the school mascot) for $5 each. The students find three companions on-line that sell stuff mascots. Company A cell's 12 eagles for $34.08. Company B cells 15 equals for $42.90. Company C charges $50.58 for 18 eagles. which company has the Best Buy?
Answer:
Company C
Step-by-step explanation:
You divide the amount of money it all costs to the number of plushies they are selling it for.
A: 34.08/12 = $2.84 each
B: 42.90/15 = $2.86 each
C: 50.58/18 = $2.81 each
So C has the least amount of money spent for a greater amount of plushies so C would be the Best Buy.

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
\(a=-15b-5\)

Five people can be in a group. There's 12 people. The combination will be 792 groups
What is the combination?Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.
The number of r-element combinations of n objects, with repetition is:
\(\overline{C}_{n,k} = \: ^{n + k-1}C_{k} = \dfrac{(n+k-1)!}{k! \times (n-1)!}\)
Thus, 5 people can be in a group. There's 12 people. So we can use combination.
12C5 = 12 * 11 * 10 *9 * 8
12C5 = 792
