Answer:
a^2
−10a+21
Step-by-step explanation:
(a−7)(a−3)
Apply the distributive property by multiplying each term of a−7 by each term of a−3.
a^2
−3a−7a+21
Combine −3a and −7a to get −10a.
a^2
−10a+21

Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms.
a. 12/24 = 18/16 = ½
b. 12/18 = 16/24 = ⅔
c. 12/16 = 18/24 = ¾
d. 18/12 = 24/16 = 3/2
Answer:
c. 12/16 = 18/24 = ¾
Step-by-step explanation:
Given
Two similar triangles
Required
Ratio of corresponding sides
To solve questions like this, you have to make comparisons between the similar sides of the triangle.
From the attached file,
Side PQ is similar to Side AB
And
Side QR is similar to Side BC
Also from the attached file
PQ = 12 and QR = 18
AB = 16 and BC = 24
Now, the ratio can be calculated.
Ratio = PQ/AB or QR/BC
Ratio = PQ/AB
Ratio = 12/16
Divide numerator and denominator by 4
Ratio = ¾
Or
Ratio = QR/BC
Ratio = 18/24
Divide numerator and denominator by 6
Ratio = ¾.
Combining these results
Ratio = 12/16 = 18/24 = ¾
Hence, option C is correct
Answer:
13.64 ounces
Step-by-step explanation:
Cost per ounce = $0.225
Cost per bag = $3.07
The number of ounces in a bag of chips is given by the cost per bag divided by the cost per ounce:
There are 13.64 ounces in a bag of chips.
