7. Triangles CDE and RST are similar triangles. What is
the length of side CD in triangle CDE?
R
40 ft.
32 ft.
20 ft.
T
S
Answers
Answer:
CD = 25 ft
Step-by-step explanation:
[tex] \triangle CDE \sim \triangle RST[/tex]
[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]
(Corresponding sides of similar triangles are in proportion)
[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]
[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]
[tex]\therefore CD = 5\times 5[/tex]
[tex]\therefore CD = 25\: ft[/tex]
Answer:
CD = 25 ft
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values
[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex] ( cross- multiply )
32CD = 800 ( divide both sides by 32 )
CD = 25

Answers
Answer:
$102.50
Step-by-step explanation:
The formula here would be x=35+15y, y being the number of hours he was there.

Answer:
$102.50
Step-by-step explanation:
35 + 15+15+15+15=95 then you break 15 into two comes out 7.50 which then makes your total $102.50
Write the compound inequality: " A number n is less than or equal to -7 or greater than 12
Answers
Let the number be n, then -1<3n+5<38 or -1≤3n+5≤38 depending on what is meant by “between”. We’ll assume the former.
-1<3n+5<38, subtract 5 throughout: -6<3n<33, divide through by 3: -2<n<11, shows the number to be in the range (-2,11) or possibly [-2,11].

Answers
Answer:
3x³
Step-by-step explanation:
Given the expression
12x^5 =(4x^2 )(C)
We are to find the value of C
Rewriting the equation will give;
(4×3)x²•x³ = 4x²C
4x²•3x³ = 4x²C
Divide both sides by 4x²
4x²•3x³/4x² = 4x²C/4x²
3x³= C
Hence the function C is 3x³

4+4+4
Step-by-step explanation:
ok so 4^3 is essentially saying 4x4x4 and 4 x 4^2 is saying 4 x 4 x 4 which is the same as 4x4x4. it is all multiplying the number 4 by itself 3 times if you try and do all three of those you will get the same answer which is 64. However if you add 4+4+4 you will get 12. I hope that makes some sense

What is unit price?Unit price cab be found by using formula ,dividing the total price by the price of of one quantity.
Formula used for finding unit price[tex]price of one item=\frac{total price }{total number of items}[/tex]
According to the given question
At the market:
Cost of 6bags of apples=$31.02
⇒ Cost of 1bag of apples [tex]=\frac{31.05}{6} =5.17[/tex]
At the orchard:
Cost of 5bags of apples =$25.40
⇒ Cost of 1bag of apples=[tex]\frac{25.40}{5}[/tex]=$5.08
Therefore, unit price of a bag of apples from orchard is less as compared to the bag of apples from market.
Hence, buying bags of apples from orchard will be the better deal as compared to the buying bags of apples from market.
