Answer:
r = 22.629
Step-by-step explanation:
Using the Pythagorean theorem:
(35 + r)² = 53² + r²
1225 + 70r + r² = 2809 + r²
subtract r² from each side of the equation:
1225 + 70r = 2809
subtract 1225 from each side:
70r = 1584
r = 22.629
1. A rectangle is 3/4 as wide as it is long. How
wide is the rectangle if it is 8 inches long?
A 5 in.
B 6 in.
C 7 in.
Answer:
B. 6 inches
Step-by-step explanation:
To find how wide it is, multiply the length by 3/4
8(3/4)
= 6
The width of the rectangle in 6 inches.
So, the correct answer is B. 6 inches

Find the 7th term of the geometric progression which begins -6250, 1250, -250....
Answer:
a(7) = -0.4
Step-by-step explanation:
The general formula for a geometric progression is a(n) = a(1)*r^(n - 1), where r is the common ratio. In this problem, a(1) = -6250. To find r, we divide 1250 (the 2nd term) by -6250 (the 1st term), obtaining r = -0.2.
Then the formula for THIS geometric progression is
a(n) = -6250*(-0.2)^(n - 1).
Thus, the 7th term of THIS progression is
a(7) = -6250*(-0.2)^(7 - 1), or -6250*(-0.2)^6, or -0.4
Answer:
a₇ = - [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
The nth term of a geometric progression is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 6250 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{1250}{-6250}[/tex] = - [tex]\frac{1}{5}[/tex] , then
a₇ = - 6250 × [tex](-\frac{1}{5}) ^{6}[/tex] = - 6250 × [tex]\frac{1}{15625}[/tex] = [tex]\frac{-6250}{15625}[/tex] = - [tex]\frac{2}{5}[/tex]

Brian has $12 and he makes $9 per hour washing cars. This can be represented as: y = 9x + 12. What does the slope represent? *
Which equation can be used to find the value of x?
Answer: D
Step-by-step explanation:
The perimeter is all the sides added up
2.5x + 2.5x + 10 + 2 + 10 =>
5x + 22
It is also given that the perimeter is 10.5x
meaning that both these values are equal
5x + 22 = 10.5x

f(x)= 3x and g(x)= -x+4, so f(g(2))=?
Answer: 6
Step-by-step explanation: first, you plug in 2 into the g(x) function. So, replace x with 2 in the second function g(x). -2 + 4 = 2. Then take that answer (2), and plug that into the x for f(x). 3 x 2 = 6
Answer:
[tex]f(g(2))=6.[/tex]
Step-by-step explanation:
We have [tex]g(x)=-x+4 \Rightarrow g(2)=-2+4=2[/tex]
Since [tex]f(x)=3x[/tex] then [tex]f(g(2))=f(2)=3.2=6.[/tex]

A store sells card games for $6.95 each. Board games sell for $15.00 each. Monica
is buying 3 card games and x number of board games. Which equation can be
used to find y, the total price Monica must pay in dollars?
Answer:
20.85+x=y
Step-by-step explanation:
Since Monica is buying 3 card games, we multiply 3*6.95. Then, we have 20.85. Then, we will add x to 20.85 to find y. So final answer is :
20.85+x=y

Calculate the breadth if the perimeter is 16cm and the length is 5cm
Step-by-step explanation:
Given,perimeter - 16cm
length - 5cm
find breadth,
perimeter of rectangle = l × b
16cm = 5 × b
b = 16/5
b = 3.2 cm
Step-by-step explanation:
Given
perimeter (P) = 16 cm
Length(L) = 5 cm
breadth (b) = ?
We know
P = 2 (L + b)
16 = 2 ( 5 + b)
16 = 10 + 2b
2b = 16 - 10
2b = 6
b = 6 / 2
b = 3 cm

The Smiths want to fence their square garden, which has an area of 289 square feet. What would be the minimum amount of fencing needed to complete the project? A) 68 feet of fencing B) 17 square feet of fencing C) 289 feet of fencing D) 17 feet of fencing
Answer:
68 feets of fencing
Step-by-step explanation:
Given that:
Area of square garden = 289 ft²
The side length of square garden can be obtained thus :
Area of a square = s²
Where s = side length
s² = 289
s = sqrt(289)
s = 17
Perimeter of square garden : 4s
Perimeter = 4* 17 = 68 feets
