Step-by-step explanation:
what percent of 25$ is 5$ no links
Answer:
20%
Step-by-step explanation:
5 20% = 100%
Answer:
20% is 5$.
Step-by-step explanation:
Ok - these always need a bit of a read to make sure we're answering the right thing.
"What percent..." asks us for a percentage. Ok - good.
"...of 25..." asks us to take the number (25) and multiply it by the percentage we're going to find.
"...is 5" tells us what the answer we're looking for is. So we have:
25 × P = 5
- 25 times some percentage equals 5.
We can treat P as a variable and so can divide both sides by 25:
p = 5/25 = 1/5 = 0.2 = 20%.
6x - 5y = 11
y = 7x + 21
Answer:
x= -4, y= -7
Step-by-step explanation:
First, label the 2 equations.
6x -5y= 11 -----(1)
y= 7x +21 -----(2)
Substitute (2) into (1) so that the first equation is only written in terms of x.
6x -5(7x +21)= 11
6x -5(7x) -5(21)= 11 (Expand)
6x -35x -105= 11
-29x= 11 +105 (Simplify, +105 on both sides)
-29x= 116
x= 116 ÷(-29)
x= -4
Substitute x= -4 into (2):
y= 7(-4) +21
y= -28 +21
y= -7

A cellular phone is in the shape of rectangular prism. The height of the phone is 6 millimeters, and the width is 50 millimeters. The volume is 22,500 cubic millimeters. What is the length of the cellular phone?
Answer: 75ml
Step-by-step explanation:
The volume of a rectangular prism is:
= Length × width × height
where,
Volume = 22500ml³
Length = Unknown
Width = 50ml
Height = 6ml
We then slot the values into the formula.
Volume = Length × width × height
22500 = Length × 50 × 6
22500 = Length × 300
Length = 22500/300
Length = 75ml
The length of the cellular phone is 75ml.
The length of a rectangle is 4 meters less than three times its width. If the perimeter of the rectangle is 48 meters, then what is the value of the length (in meters)?
Answer:
7
Step-by-step explanation:
Think about it visually. 3x-4 is the length and x is the width. Since a rectangle has 2 parralel and equal sides, it's just double those. The equation is 8x-8=48. 48 is the total as given in the problem.
8x-8=48
8x=56
x=7
The width is 7
Can someone tell me what x= to and y=?
Answer:
x = 112
y = 76
Step-by-step explanation:
x + 68 = 180
x = 180 - 68
x = 112
y = 76 (Because of alternate interior angles)

Answer
[tex]18\pi[/tex]
Step-by-step explanation:
[tex]\pi \times diameter \\ = \pi \times 18[/tex]
Answer: 56.52
Step-by-step explanation: Circumference is found by using 2πr. Since diameter is twice of radius, this formula can also be used as C = πd. So the circumference will be 18 * 3.14 (which is approximate for π). This gives us the answer of 56.52.

the initial starting salary for a summer camp counselor is $14 per week. Starting with the first week, the salary doubles to encourage counselor to work for the entire summer. Write an equation that models the salary (y) of the camp counselor per week (x). if the camp runs for 12 weeks, how much would a camp counselor make?
Answer:
The equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.
Step-by-step explanation:
Since the initial starting salary for a summer camp counselor is $ 14 per week, and starting with the first week, the salary doubles to encourage the counselor to work for the entire summer, to write an equation that models the salary (y) of the camp counselor per week (x), and determine, if the camp runs for 12 weeks, how much would a camp counselor make, the following calculations should be performed:
14x2 ^ X = Y
14x2 ^ 12 = Y
14x4,096 = Y
57344 = Y
Therefore, the equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.

Alexis has a wooden box that is shaped like a rectangular prism. The box measures 8 in. Wide, 9 in. Long, and 4 in. Tall on the outside. The wood used to make the box is 1/2 in. Thick. What is the inside volume of the box? A. 144 in. Cubed B. 168 in. Cubed C. 223 in. Cubed D. 288 in. Cubed Pls show work
Answer:
B. 168 in. Cubed
Step-by-step explanation:
Given that
The box measures 8 in. Wide, 9 in. Long, and 4 in. Tall on the outside.
And, the wood be used to make the box is 1 ÷2 in
We need to find out the inside volume of the box
As we know that
Volume = (length)(width)(height)
= (8 - 0.5 × 2) (9 - 0.5 × 2 ) (4 - 0.5 × 2)
= 7 × 8 × 3
= 168 cubic inches
hence, the second option is correct

If we can show
then EH || FG
Answer:
D
Step-by-step explanation:
The answer is D because A and B is an alternate interior angle meaning they don't have to be parallel lines in order to show that they are the same angles. C is incorrect.
E is incorrect because perpendicular lines mean that they have to be 90 degrees angle but the one that is shown is diagonal instead.
If we can show ∠4 ≅ ∠8 then EH || FG. [option A]
What are parallel lines?Two lines are said to be parallel if they do not meet each or intersect each other and have same slope.
Given is a quadrilateral EFGH, we need to determine a reason that can show EH || FG.
So, we know if two alternate angles between two lines are equal then the lines will be parallel by converse of alternate angles theorem.
Here, ∠4 and ∠8 are alternate angles, so if we show that ∠4 ≅ ∠8 then we can conclude that EH || FG.
Hence the correct option is A.

Answer:
(24,4,84)
Step-by-step explanation:
Since they restricted our domains to certain x values, we can find the range by plugging in the x values to find it y value or output.
[tex]f( - 2) = 5( { - 2}^{2} ) + 4[/tex]
[tex]5(4) + 4 = 24[/tex]
[tex]f(0) = - 5( {0}^{2} ) + 4 = 4[/tex]
[tex]5(4) {}^{2} + 4 = 84[/tex]
So our range is (24,4,84)
Answer:
f(x)=5x²+4
f(-2)=5×(-2)²+4
5×4+424f(0)=5(0)²+4
0+44f(4)=5×(4)²+4
5×16+484so the range of function{-2,0,4}is{24,4,85}
