Answer:
120 girls chose the lighter shade
Step-by-step explanation:
For every 4 girls that preferred a lighter shade of blue jeans, 3 girls preferred a darker shade.
This question has to do with ratio and proportions.
For every 4 girls that preferred a lighter shade of blue jeans, 3 girls preferred a darker shade.
We have a ratio of Lighter shade to darker shade
Lighter shade: Darker shade
= 4:3
Sum of proportions = 4 + 3 = 7
Total number surveyed = 210
If a total of 210 girls were surveyed, how many chose the lighter shade?
This is calculated as:
4/7 × 210 girls
= 120 girls
Therefore, 120 girls chose the lighter shade

The tennis ball has a radius of 12 cm. Calculate the volume of the tennis
ball.
Answer:
7234.56 [tex]cm^{3}[/tex]
Step-by-step explanation:
The formula for the volume of a sphere is [tex]\frac{4}{3} \pi r^{3}[/tex] where r is the radius. Since [tex]\pi[/tex] is irrational (whose digits goes on forever without repeating), we can write it using the first three numbers: 3.14. Then, substiute 12 for r and 3.14 for [tex]\pi[/tex] into the formula, and you’ll get 7234.56. Finally, add the [tex]cm^{3}[/tex] part to it to get the answer: 7234.56 [tex]cm^{3}[/tex]

Step 1: Define Equation
2(6x + 4) - 6 + 2x = 3(4x + 3) + 1
Step 2: Solve for x
Distribute: 12x + 8 - 6 + 2x = 12x + 9 + 1Combine like terms: 14x + 2 = 12x + 10Subtract 12x on both sides: 2x + 2 = 10Subtract 2 on both sides: 2x = 8Divide 2 on both sides: x = 4Sorry about the rainbow stuff but what’s the answer

measure of angle A = 5 X, measure of angle B = 2X, measure of angle C = 110 degrees
i need help finding x (its a triangle btw)
Answer:
A = 50
B = 20
C = 110
Step-by-step explanation:
A triangle is equal to 180°
In order to find the measure of each angle, add angle A, B, and C to get 180°
If angle A = 5x, angle B = 2x and angle C = 110 then 5x + 2x + 110 = 180°
To find each angle, first solve for x:
5x + 2x + 110 = 180° start by adding like terms
7x + 110 = 180° now subtract 110 from 180
7x = 70 finally divide 7 from 70
x = 10
To find each individual angle, substitute x with 10. For example:
A = 5x
A = 5(10)
A = 50
B = 2x
B = 20
C = 110
If you were to add A, B, and C it should equal 180°
110 + 20 + 50 = 110

Write a linear equation with the given information. Passing through (2, 3) and PARALLEL to y = x - 4
Which is true about the vertex?
1. It's halfway between the y-intercepts.
2. All of these are true.
3. It's equal to the "a" value.
4. It's equal to the "c" value.
5. It's halfway between the x-intercepts.
Answer:
5. It's halfway between the x-intercepts.
Step-by-step explanation:
The vertex is halfway between the two x-intercepts when parabola is coordinate of the vertex. The points and x and y intercept crosses the x-axis vertically so that a u shaped lines are formed. The quadratic equation is used to find the points on the parabola.

The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?
y = 12x + 0.75
y = 0.75x + 12
y = 12x – 0.75
y = 0.75x – 12
Answer:
THE ANSWER IS A Y=12x+0.75

Answer:
1 !
Step-by-step explanation:
it is 1 1/4 units to the left and 3/4 of a unit up
9514 1404 393
Answer:
1) (-1 1/4, 3/4)
Step-by-step explanation:
Coordinates in two dimensions are given as an ordered pair, (x, y). That is, the x-coordinate is always listed first, followed by the y-coordinate.
The x-coordinate is the distance to the right of the x=0 point, or y-axis. Distances to the left have a negative sign. Here, the given point is 5 grid squares to the left of the y-axis, so has an x-coordinate of -5/4 = -1 1/4. (Each grid square on this graph is 1/4 unit.)
The y-coordinate is the distance above the y=0 point, or x-axis. Distances below have a negative sign. Here, the given point is 3 grid squares above the x-axis, so has a y-coordinate of 3/4.
The coordinates of the given point are (x, y) = (-1 1/4, 3/4).
_____
Additional comment
The above discussion refers to coordinates on the "Cartesian plane." There are other ways of determining location. Some are based on the distance from an origin and an angle from a reference direction. Then, the ordered pair is not (distance right, distance up), but may be (distance from origin, CCW angle from 'right'). In navigation, it may be (latitude angle, longitude angle), or (bearing distance, bearing angle CW from North).

Enter an equation to represent the amount of moneys, in dollars, in Jack's account after w weeks, in simplest terms.
what is the answer?
Answer:
[tex]x = 27[/tex]
Step-by-step explanation:
Angle A and angle E are the same value, therefore you could replace angle E with angle A. So that would make a triangle with angle C, angle D, and angle A. Knowing the sum of all angles in a triangle is 180, we can make an equation representing this.
[tex]3x - 10 + 2x + 10 + 45 = 180[/tex]
Now simply silve the equation to find x.
[tex]5x + 45 = 180 \\ 5x = 135 \\ x = 27[/tex]
There is your answer.
Only answer if you know please
Answer:
(b)
Step-by-step explanation:
Since the hypotenuse is not known then this excludes sine/ cosine ratios
Using the tangent ratio in the right triangle
tan38° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{6}{a}[/tex] ( multiply both sides by a )
a × tan38° = 6 ( divide both sides by tan38° )
a = [tex]\frac{6}{tan38}[/tex] → (b)

22 – 2 = 4.1 - Y-1
(1,3)
(3,1)
(-1-3)
None of the above
Answer:
(1,3)
Step-by-step explanation:
2x-2=4x-y-1
subtract 2x on both sides
-2=2x-y-1
add y on both sides
y-2=2x-1
add 2 on both sides
y=2x+1

A shopper pays $87.15 for an $83 ceramic vase after sales tax is added. What is the sales tax percentage?
Answer:
5% or $4.15
Step-by-step explanation:
Answer:
5%
Step-by-step explanation:
sales tax: 87.15-83 = 4.15
4.15/83 = 0.05
to convert decimal to percentage multiply by 100
0.05*100 = 5%
