Answer:
Each girl (m) had $18.
Step-by-step explanation:
They each had $18.Then, they each spent $12.So, they each have $6; 6x4 = $24 leftThe Equation to determine the amount of money, m, each girl received is 4m = 72 or m = 12(4) + 24
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Each girl spent $12.
Afterward, the girls had $24 altogether.
let each Girl received amount of $x.
So, the four spend = 12 x 4 = $48
Then, the total they have = 48 + 24 = $72
So, each of Girl have = 72/ 4 = $18.

Jessica is planting a garden. It has the shape of a right triangle. She wants 4 plants for each square yard of area. How many plants does she want in the garden?
A right triangle has a base of length 9 yards and a height of 12 yards. The longest side has length 15 yards
Answer:
216 plants
Step-by-step explanation:
To answer this question :
Determine the area of a triangle Multiply the area of the triangle by the number of plants per square yardArea of a triangle = 1/2 x base x height
1/2 x 9 x 12 = 54 yards²
54 x 4 = 216 plants

Graph y = x2 - 8x + 13
Answer:
Step-by-step explanation:
From the given x^2 - 8x + 13 we can find several points to graph to represent this quadratic function.
The y-intercept is (0, 13) and stems from letting x = 0.
b
The axis of symmetry is x = - -----
2a
-8
Since a = 1 and b = -8, the axis of symmetry is x = - ------- = 4
2(1)
and so the vertex is at (4, 4^2 - 8(4) + 13), or (4, -3)
If you want to go the extra mile, find the roots of the given equation. These are also your x-intercepts. One such intercept is (2. 0).
Plot these points and draw a smooth curve through them.
Hint: the parabolic graph opens up.

Find the value of X in this hexagon
Answer:
x = 130°
Step-by-step explanation:
number of sides = 6
the sum of the total interior angles = (6 x 180) - 360 = 720°
x = 720 - 125 - 120 - 100 - 120 - 125 = 130°

Jasmine bought a new stereo system for $480.50 if the tax rate is 6 1/2 what was the total cost of the stereo system?
Answer:
$511.7
Step-by-step explanation:
Given data
Cost of stereo system= $480.50
Tax= 6 1/2% = 6.5%
Let us find the amount of the tax
=6.5/100*480.5
=0.065*480.5
=$31.2
Hence the amount of the tax = $31.2
Therefore the total cost is
=31.2+480.50
=$511.7

Answer:
79 degrees.
Step-by-step explanation:
There are 7 total temperatures, 68, 82, 81, 82, 74, 75, and 91 degrees. To find the mean, we add all of the temperatures together and divide it by the number of tempuratures-- 7.
68+82+81+82+74+75+91 = 553.
553 / 7 = 79.

-8a -8a
-3 does not equal to 35
NO SOLUTIONS
Answer: 8a=38+8a²
Step-by-step explanation:
8a-3=5(a+7)+3a
8a-3=5a+35+3a
8a-3=8a²+35
8a=35+3+8a² (I moved 3 to put it with 35 because they are the same, I couldn't do the same for 8a and 8a² because of the 2)
8a=38+8a²

Quintaveous that its current value is $250 and that each year the value will grow at
a rate of 10%. What is the approximate value of the card after 6 years?
Group of answer choices
$310
$500
$133
$443
Answer:
the approximate value after 6 years is $443
Step-by-step explanation:
The computation of the approximate value after 6 years is shown below:
= Current value × (1 + rate of interest)^number of years
= $250 × (1 + 0.10)^6
= $250 × 1.1^6
= $442.8903
= $443
Hence, the approximate value after 6 years is $443
Therefore the last option is correct
solve the system of equations -4x- y = -18 and 2x + 3y = 24 by combining the equations
Answer:
x = 3
y = 6
Step-by-step explanation:
-4x- y = -18
2x + 3y = 24 (Multiply everything by 2)
-4x - y = -18
4x + 6y = 48
5y = 30
y = 6
-4x- y = -18
-4x - 6 = -18
-4x = -12
x = 3

In circle A shown below, BD is a diameter and the measure of CB is 36°:
What is the measure of angle DBC? (4 Points)
Answer:
54degrees
Step-by-step explanation:
Find the diagram attached
Since the angle of the triangle in a semicircle is a right angle, hence <DCB = 90 degrees
Given
<DBC= 36 degrees
Required
<DBC
Since the sum of angles in the triangle DBC is 180 degrees, hence;
<DBC+<DBC+<DCB = 180
<DBC+36+90 = 180
<DBC + 126 = 180
<DBC = 180 - 126
<DBC = 54degrees
Hence the measure of angle DBC is 54degrees

Graph the quadratic inequality of y>x^2+6x+6
Answer:
Step-by-step explanation:
Triangle XYZ is inscribed in semicircle O shown below such that YZ = 7 and YX = 10. Which of the following
is closest to the radius of the semicircle?
(1) 5.8
(2) 6.1
(3) 11.6
(4) 12.2
Answer:
(2) 6.1
tep-by-step explanation:
∠Y is a right angle, so ΔXYZ is a right triangle
[tex]XZ^{2} = XY^{2} + YZ^{2}[/tex]
[tex]XZ^{2} = 7^{2} + 10^{2}[/tex] = 49 + 100 = 149
XZ = [tex]\sqrt{149}[/tex] = 12.2
XZ is the diameter of the semicircle, therefore, the radius is 12.2/2 = 6.1

Kaitlyn makes 65% of her free throws on the basketball court. If she attempts 50 free throws in practice, about how many would you expect her to make?
Answer: Its 33 !
Step-by-step explanation:
Okay so its actually not that bad at all !
So STEP 1
Convert your percent into a decimal : 65% --> .65
STEP 2 you still following me you got this !
since kaitlyn attempts to throw 50 free throws all you need to do is multiply your decimal you converted by 50
it would look like this .65 X 50 = 32.5
Step 3
Depending on what your answer choices are 32.5 is going to have to be rounded upwards remember anything at or above 5 you round up. Anything below 5 you round down so your answer will be 33 in this problem
Summary
when seeing questions like this convert that percent into a decimal then depending on what is being counted for. you multiply your decimal by the number ! Hope this helps thanks for reading <3
