The ratio of boys to girls in a group is 7:3 There are 60 more boys than girls. Work out how many girls are there?
Answer:
45 girls
Step-by-step explanation:
There is 4 more boys than girls in each ratio.
60 boys / 4 = 15 groups where there is more boys
3 (girls) x 15 groups = 45 girls in total
The graph of a function is given below.

If there is more than one answer, separate them with commas.
Click on "None" if applicable.
Answer:
Y-intercept=(0, 2)
X-intercepts=(-4,0) & (-2,0)
Step-by-step explanation:
X and y- intercepts are determined when they pass through either the x or y axis. If the line passes through the x axis it is the x-intercept and vice versa for y.

The cities Alex could have drove between whose distance is about 2000 miles when rounded to the nearest thousand are : Chicago to San Francisco and Atlanta to Los Angeles
From the table attached which shows the distance in miles between two cities in the United States :
Distance between Chicago to San Francisco = 2131Distance between Atlanta to Los Angeles = 2173Only the distances between these two cities would give a value of 2000 miles when rounded to the nearest thousand mile

What is the slope of the line y=-4
Answer:
The slope is zero
Step-by-step explanation:
y = -4 is a horizontal line
Horizontal lines have a slope of zero
Hello there! The line y=-4 is a horizontal line and the slope of horizontal lines is 0.
Why? Because we calculate the slope using the formula Rise/Run. The rise is 0 (how many units we go up) so no matter what the run is, if we divide 0 by any number, we will get 0 100%.

Which pairs of rectangles are similar polygons?
Select each correct answer.
Similar polygons will have proportional side lengths. So, let's check each of these using proportions and cross-multiplying.
Proportion: left rectangle length / left rectangle width = right rectangle length / right rectangle width
Top Left Rectangles: Proportional
6.4 / 5.6 = 1.6 / 1.4
8.96 = 8.96
Top Right Rectangles: Not Proportional
10.2 / 6.2 = 5.2 / 1.2
32.24 does not equal 12.24
Bottom Left Rectangles: Proportional
39 / 27 = 13 / 9
351 = 351
Bottom Right Rectangles: Not Proportional

The image of point (−3, 5) under translation T is (6, -8). What is the image of point (4, 7) under the same translation?
Answer:
(13,-6)
Step-by-step explanation:
If you are at (-3,5) and you translate T to give you (6,-8), that means you translated (9,-13) because you moved right 9 units in the positive x direction and down 13 units in the negative y direction.
Apply this translation T to (4,7) and you get (13,-6).
Answer:
(13, -6)
Step-by-step explanation:
Firstly, we need to find the translation. This can be achieved by calculating the amount the x and y coordinate shifts. Simply use the following equation:
[tex](x2 - x1, y2 - y1)[/tex]
Where x1 and y1 are the coordinates of the first set and x2 and y2 are the second. Plug the variables in:
[tex](6 - (-3), -8 - 5)\\(9, -13)[/tex]
So the x coordinate is shifted 9 positively and the y coordinate is shifted 13 negatively.
To calculate the new translation of the new point, add the translation onto the given coordinates:
[tex]( 4 + 9, 7 + (-13) )\\(13, -6)[/tex]
So the new point is (13, -6).
Hope this helps!

Step-by-step explanation:
In a trial, an expert witness uses the conservation of momentum to demonstrate which initial velocities would give the final states that occurred in the accident. Can using the conservation of momentum be justified in this case? Yes, because momentum is conserved in all collisions. No, momentum is only conserved in elastic collisions which this is not. No, energy is always conserved, but momentum is only sometimes conserved. Yes, because momentum is conserved in inelastic collisions which all car accidents are.
Answer:
Yes, because momentum is conserved in all inelastic collisions which all car accidents are
Step-by-step explanation:
What is law of conservation of momentum?
It states that In a equilibrium the initial momentum is equal to to the final momentum of the body
Or

Answer:
• Yes, because momentum is conserved in all collisions.
Step-by-step explanation:
→ Elastic collision, inelastic collision and perfectly inelastic collision, linear momentum is conserved assuming no external forces acting on the system.
In elastic collision
[tex] \dashrightarrow \: { \tt{m _{1}u _{1} + m _{2} u_{2} = m_{1}v_{1} + m_{2}v_{2}}} \\ [/tex]

8) Cashews cost $8.90 per pound. If Austin buys 2.45 pounds of cashews, what is the total cost?
Round to the nearest.cent.
$
Answer:
9.00 and 2.00
Step-by-step explanation:
8.90 rounds to 9.00 because 8.90 is more than more then 0.50 so it makes the cents round to the nearest cent. 2.45 round to 2.00 because 2.45 is less than 0.50
Solve T=2x + 3y - z for y.
Answer:
[tex]\frac{T+z-2x}{3}[/tex]=y
Step-by-step explanation:
On solving for y we get -
[tex]$y=\frac{T-2x+z}{3}[/tex]
We have the following expression -
T = 2x + 3y - z
We have to solve for ' y '.
Solve for x : Sin([tex]2n\pi x[/tex]) = 0.785 .On solving, we get -
Sin([tex]2n\pi x[/tex]) = 0.785
Sin([tex]2n\pi x[/tex]) = Sin ([tex]\frac{\pi }{4}[/tex])
2n[tex]\pi[/tex]x = [tex]\frac{\pi }{4}[/tex]
x = [tex]\frac{1}{8n}[/tex]
According to the question, we have -
T = 2x + 3y - z
T - 2x + z = 3y
[tex]$y=\frac{T-2x+z}{3}[/tex]
Hence, on solving for y we get -
[tex]$y=\frac{T-2x+z}{3}[/tex]

A line passes through (-2,4), (-4, 8), and (n, -4). Find the value of n.
Answer: n = 2 ....... (2, -4)
Step-by-step explanation:
To find n, one must write the equation for the points given, which are (-2, 4) and (-4, 8). Remember, the standard linear equation is y = mx + b, where m is the slope of the line.
To find the slope, refer back to (y2-y1)/(x2-x1), or in this case, (8-4)/(-4+2), which gives us -2
With our slope of -2, we can write the equation as y = -2x+b. Now, we need to find b (the y-intercept) by plugging in a point as (x,y)
Let's use (-4,8) point and plug it into our linear equation: y = -2x+b
to get 8=(-2)(-4) +b
8=8+b
0=b (which means our y-intercept is 0)
Now, our official linear equation is y=-2x
The problem gives us (n, -4) where -4 y, so we plug in -4 as y in the equation to get:
-4=-2x
-4/-2=x
2 = x
And there we go :) I hope this helps!
Answer:
The value of n = 2.
Step-by-step explanation:
Given the following points passing through a line, (-2, 4), (-4, 8), and (n , -4) wherein we must find the value of n:
It helps to determine the equation of the line, using the slope-intercept form: y = mx + b, where:
m = slope (rate of change), which measures the steepness of the line.b = y-coordinate of the y-intercept; it is the point on the graph where it crosses the y-axis. Slope:In order to solve for the slope of the line, use the following slope formula:
[tex]\displaystyle\mathsf{m =\:\frac{y_2 - y_1}{x_2 - x_1}}[/tex]
Let (x₁, y₁) = (-2, 4)
(x₂, y₂) = (-4, 8)
Substitute these values into the slope formula.
[tex]\displaystyle\mathsf{m =\:\frac{y_2 - y_1}{x_2 - x_1}}[/tex]
[tex]\displaystyle\mathsf{m =\:\frac{8 - 4}{-4 -(-2)}\:=\:\frac{4}{-4+2}\:=\Frac{4}{-2}\:=\:-2}[/tex]
Hence, the slope of the line is: m = -2.
Y-intercept:Next, we must solve for the y-intercept. Since it is the point where the graph crosses the y-axis, set x = 0 and solve for the value of y.
Use the slope, m = -2, and one of the given points, (-2, 4), and substitute these values into the slope-intercept form to solve for the value of the y-intercept, b:
y = mx + b
4 = -2(-2) + b
4 = 4 + b
Subtract 4 from both sides:
4 - 4 = 4 - 4 + b
0 = b
The y-intercept is: b = 0.
Linear Equation in Slope-intercept Form:Therefore, the equation of the line in slope-intercept form is:
y = -2x + 0 or y = -2x.
Find the value of n in (n, -4)In order to determine the value of n, substitute its corresponding y-coordinate, -4, and substitute into the equation in the previous step:
Set y = -4:
y = -2x
-4 = -2x
Divide both sides by -2 to solve for x:
[tex]\displaystyle\mathsf{\frac{-4}{-2}\:=\:\frac{-2x}{-2}}[/tex]
x = 2
Therefore, the value of n = 2.
