Answer:
a) For Cole = 60%
b) For Jamie = 72 %
Step-by-step explanation:
Cole and Jamie are raising money for the annual Walk for Hunger in their city. They each have a goal to raise $250. So far, Cole has raised $150 and Jamie has raised $180.
What percent of their goal did each boy raise so far?
a) Percent of Cole's goal
= Amount raised by Cole/ Total amount × 100
= $150/$250 × 100
= 60%
b) Percent of Jamie's goal
Amount raised by Jamie / Total amount × 100
= $180/$250 × 100
= 72%
-7x - 12 = - 7х + 3(-4 - x)

[tex]x=0[/tex]
Step-by-step explanation:
[tex]-7x - 12 = - 7x + 3(-4 - x)[/tex]
Open up the parentheses

What is the answer to this math question “X - 3 = 6”
Answer: x = 9
Step-by-step explanation:
x can be equal to 9.
Lets plug in 9 to the variable x, in this equation, x -3 = 6.
x - 3 = 6
9 - 3 = 6 (plugged in 9 for x)
So, x = 9.
Answer:
x-3=6
The correct answer is x=9
Step-by-step explanation:
9-3=6

I need help solving the equal method
Answer:
(-2, -4)
Step-by-step explanation:
Since both equations are equal to y, you can set them equal to each other:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]
Next, solve for x:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]
Finally, substitute the solution for x in one of the equations (or both) to find y:
[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]
[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]
Therefore, the solution to the system of equations is (-2, -4).
The medians of TUV are TX, UY, and VW. They meet at a single point Z.
(In other words, Z is the centroid of TUV.)
Suppose UZ=8, VW=33, and ZX=5.
Find the following lengths.
Note that the figure is not drawn to scale.
Answer:
TZ = 10 units
UY = 12 units
ZW = 11 units
Step-by-step explanation:
Point Z is the centroid of ΔTUV.
Since, centroid of a triangle is located on each median so that it divides each median in the ratio of 2 : 1
Therefore, TZ = 2(ZX)
TZ = 2(5) = 10 units
UY = UZ + ZY
= UZ + [tex]\frac{1}{2}(UZ)[/tex]
= [tex]\frac{3}{2}UZ[/tex]
= [tex]\frac{3}{2}\times 8[/tex]
= 12 units
ZW = [tex]\frac{1}{3}(VW)[/tex]
= [tex]\frac{1}{3}(33)[/tex]
= 11 units

Answer:
Step-by-step explanation:
This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.
If you have a triangle that hast angles of 100 50 and 30
The largest side will be opposite the 100 degree angle.
The smallest side will be opposite the 30 degree angle.
So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.
So the answer is Since 43 > 40 then CD>AB

What is an equation of the line that passes through the point (6,7) and is parallel to the line 2x-3y=92x−3y=9?
Answer:
y = ²/₃x + 3Step-by-step explanation:
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
Changing to slope-intercept form:
2x - 3y = 9 {subtract 2x from both sides}
-3y = -2x + 9 {divide both sides by (-3)}
y = ²/₃x - 3 ⇒ m₁=²/₃ ⇒ m₂=²/₃
The line y=²/₃x+b passes through point (6, 7) so the equation:
7 = ²/₃×6 + b is true
7 = 4 + b
b = 3
Therefore equation in slope-intercept form:
y = ²/₃x + 3
The equation of the line passing through the point (6, 7) parallel to the line is y = 2/3x + 3
The equation in slope - intercept form :
2x - 3y = 9
-3y = 9 - 2x
Divide both sides by - 3
y = - 3 + 2/3x
Using the points (6, 7)
7 = c + 2/3(6)
7 = c + 12/3
7 = c + 4
c = 7 - 4 = 3
c = 3
The equation of the parallel line is thus :
y = 2/3x + 3Learn more : https://brainly.com/question/18106342

Answer:
Option A. – 3
Step-by-step explanation:
From the question given above, the following data were obtained:
y = 3/4
xy² = 9/16
(x – 4) =?
Next, we shall determine the value of x. This can be obtained as follow:
y = 3/4
xy² = 9/16
x(3/4)² = 9/16
x (9/16) = 9/16
Divide both side by 9/16
x = 9/16 ÷ 9/16
x = 1
Finally, we shall determine the value (x – 4). This can be obtained as follow:
(x – 4)
x = 1
(x – 4) = 1 – 4
= – 3
Here are the weekly allowances for 10 Grade 7 students:
$9, $11, $13, $15, $20, $10, $12, $15, $10, $15
What is the mean allowance?
Mean allowance of the given students is equals to $13.
What is mean?
" Mean is defined as the ratio of the sum of all the given number to the total number of numbers. It is also known as average."
Formula used
Mean = [tex]\frac{Sum of all the given numbers}{Total number of numbers}[/tex]
According to the question,
Number of students = 10
Weekly allowances of each student
= $9, $11, $13, $15, $20, $10, $12, $15, $10, $15
Substitute the value in the formula of mean we get,
mean = [tex]\frac{9+11+12+13+20+2(10)+3(15)}{10}[/tex]
[tex]= \frac{130}{10}\\ \\= 13 dollars[/tex]
Hence, mean allowance of the given students is equals to $13.

If triangle PML ~ triangle TRQ, find QR.
im stuck on the same problem
The measure of QR, from the triangle TRQ is 16 units.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Given that, triangle PML is similar to triangle TRQ.
From the given triangles.
ML/QR =PM/TR
(7x-9)/(2x+2) = 35/14
(7x-9)/(2x+2) = 5/2
2(7x-9)=5(2x+2)
14x-18=10x+10
4x=28
x=7
Then, QR=2x+2=16 units
Therefore, the measure of QR is 16 units.

Given:
The increase in pressure P is the linear function of the depth d.
[tex]P(d)=0.445d+14.7[/tex]
The cost of dinner is $300 and $10 per students.
To find:
The initial value and rate of change and their interpretation.
Find the cost function C where n is the number of students.
Solution:
The slope intercept form of a linear function is
[tex]f(x)=mx+b[/tex] ...(i)
where, m is rate of change and b is y-intercept or initial value.
We have,
[tex]P(d)=0.445d+14.7[/tex] ...(ii)
From (i) and (ii), we get
[tex]m=0.445,b=14.7[/tex]
The initial value is 14.7. It means, the pressure at sea level is 14.7 pounds psi.
Rate of change is 0.445. It means, the pressure is increasing by 0.445 pounds psi for every feet.
The cost of dinner is $300 and $10 per students.
Let C(n) be the total cost for dinner and n be the number of students.
Fixed cost = $300
Additional cost for 1 student = $10
Additional cost for n student = $10n
Now,
Total cost = Fixed cost + Additional cost
[tex]C(n)=300+10n[/tex]
Therefore, the required cost function is [tex]C(n)=300+10n[/tex].
