A tool box has the dimensions of 9 in by 3 in by 5 in. If Jesse plans to double all three dimensions to build a larger tool box, he believes he would double the volume of the tool box. Is he correct?
Answer:
No, the volume will be incresed by 8 times (2x2x2=8)
Step-by-step explanation:
[tex]Volume=3*5*9=135 in^{3} \\increased -Volume=6*10*18=1080 in^{3}\\\frac{1080}{135} =8[/tex]

Which expression represents the series 1+5+25+125+625
Answer:
[tex]1 = {5}^{0} [/tex]
[tex]5 = {5}^{1} [/tex]
[tex]25 = {5}^{2} [/tex]
[tex]125 = {5}^{3} [/tex]
[tex]625 = {5}^{4} [/tex]
option A is correct, it starts with the power of zero (equals always one, see it as
[tex] \frac{5}{5} [/tex]
and it goes up to the power of 4

Find the circumcenter of a triangle ABC with vertices at A(2, 2), B(0, -4), and C(7, -1)
20 POINTS PEOPLE
Answer:
just sum up the 3 sides.
quick side note: I lost my previews writing bc I waited too long too post it :(
but long story short: you get the length of, say, AB by using pythagoras theorem.
[tex] \sqrt{ {2}^{2} + {6}^{2} } [/tex]
do this with BC and CA too
the 2 is just the distance in x-direction and the 6 is just the distance in y-direction
and since a²+b²=c², we need to take the root to get the distance between 2 points
see screenshot for summing up the three distances. the part out of screen is written out above
the sum is 21.011 length units
hope it helps. have a nice day.

The width of an extra large rectangle poster is 8 inches more than half its length.The area of this poster is 306 square inches
Answer:
a² + 16a - 612 = 0
Step-by-step explanation:
Here is the complete question :
The width of an extra large rectangle poster is 8 inches more than half its length. The area of this poster is 306 square inches
Write an equation in one variable that could be used to find the number of inches in the dimensions of this poster.
Area of a rectangle = length x width
Let length = a
width = 8 + 1/2a
Area = (8 + 1/2a) x a
306 = (8 + 1/2a) x a
multiply both sides of the equation by 2
612 = 16a + a²
a² + 16a - 612 = 0
the dimensions of the poster can be determined using quadratic formula

(ii) 3x - 5y - 4 = 0 and 9x = 2y +7
Step-by-step explanation:

-6x-7y =-7
Answer:
[tex]x = \frac{9}{13} \ , \ y = - \frac{5}{13}[/tex]
Step-by-step explanation:
3x - 5y = 4 ----------- ( 1 )
9x - 2y = 7 -----------( 2 )
______________________
( 1 ) x 9 => 27x - 45y = 36 ----------------- ( 3 )
( 2) x 3 => 27x - 6y = 21 -------------------( 4 )
_____________________
( 3 ) => 27x - 45y = 36
- ( 4 ) => -27x + 6y = - 21
____________________
( 3 ) - ( 4 ) => 0x - 39y = 15
-39y = 15
[tex]y = \frac{15}{-39} = -\frac{5}{13}[/tex]
Substitute y in ( 1 ) :
[tex]3x - 5y = 4\\\\3x - ( 5 \times -\frac{5}{13}) = 4\\\\3x + \frac{25}{13} = 4\\\\3x = 4 - \frac{25}{13}\\\\3x = \frac{52 - 25}{13}\\\\3x = \frac{27}{13}\\\\x = \frac{27}{13 \times 3}\\\\x= \frac{9}{13}[/tex]

Answer:
25
Step-by-step explanation:
Answer:
x = 25
Step-by-step explanation:
Okay so as you can see there is an x shape and whenever you have that it means they are verticle angles. So we can conclude that 25 is verticle to x and so x is equal to 25.

Callie surveyed 40 students at her school to see how many have dogs and/or cats. She found that 40% of students who have dogs, don't have cats.
Complete the table below.
Answer:
60 students don't have dogs
Step-by-step explanation:
Given data
number of students survayed= 40 students
40% of students have dogs
We can further find the number of students who have and don't have dogs
40/100*x= 40
0.4*x=40
x=40/0.4
x= 100 students
This means 60 students dont's have dogs

AB = [ 2 ]in
Answer:
Length arc AB = 3.14 in
Step-by-step explanation:
Length of arc AB = central angle/360 * 2πr
Central angle = 30°
Radius (r) = 6 in.
Substitute
Length of arc AB = 30/360 * 2*π*6
Length arc AB = 3.14 in. (Nearest tenth)

What is the solution of -17 = -2y + 13 – 8y?
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10
y = 3
Which best describes the domain and range of the function y = = 4x²?
Answer:
Domain: (-infinity, infinity)
Range: [0, infinity)
Step-by-step explanation:
y = 4x^2 is a quadratic function whose parabolic graph goes through (0, 0) and opens upward. (0, 0) is both the vertex and the minimum of this function and graph. Here x can take on any value, but y is limited to [0, infinity).
