Sahil got 28 questions right on the math test. Angelina got 7 more wrong answers than Sahil. There were 40 questions on the test. How many answers did Angelina get right on the math test? Which equation represents this situation?
A. a + 7 = 12
B. a + 7 = 28
C. 7 + 12 = a
D. 7 = 40 - a
Answer:
40-28=12 Sahil got 28 right and 12 wrong
12+7=19 Angelina got 19 wrong and 21 right
40-19= 21
B would be correct
a +7=28
a= 28-7
a=21

Monica has been saving her spare change. So far she has saved 40 coins for a total of $6.25. Some of the coins are quarters (25 cents) and the rest are dimes (10 cents). How many of each coin does she have?
Use elimination to solve.
{q+d=40
{25q+10d=625
Answer:
10 quarters
40 dimes
Step-by-step explanation:
q + d = 40
25q + 10d = 625
25 > 10
q < d
25(10) = 250
10(40) = 400
$2.50 + $4.00 = $6.00
Answer:
15 quarters and 25 dimes

Answer:
96×pi ft³
Step-by-step explanation:
by the way, it is totally easy to search for formulas on the internet.
the volume of a cone is
Vc = pi×r²×height/3
we have been given the slant height (10 ft) and the lateral "wall" area of the cone (60×pi ft²).
this wall area is
Aw = pi×r×slant height
60×pi = pi×r×10
60 = r×10
6 = r
so, now we know r fuer the volume formula, and we need the height of the cone (the inner one).
we use Pythagoras
10² = r² + height²
100 = 36 + height²
height² = 64
height = 8 ft
so, now we use the main formula for the volume
Vc = pi×r²×height/3 = pi×6²×8/3 = pi×36×8/3 = pi×12×8 =
= 96×pi ft³
cubic feet ! it is a volume !
The area of a square piece of land in square units can be represented by the expression 9q^4r^8s^6What is the length
of one side of the piece of land?
Answer:
I'll setup the problem, you do the calculation
Step-by-step explanation:
given the area of a square, you take the square and that is the side of the square
[tex] \sqrt{9 {q}^{4} {r}^{8} {s}^{6} } [/tex]
the square root of a number that is raised to a power is found by dividing the power by 2
example
[tex] \sqrt{ {x}^{6} } = {x}^{3} [/tex]

Find m∠1 and m∠2. Tell which theorem can be used.
Answer:
1 = 117 ( vertically opposite angles are equal )
2 = 117 ( corresponding angles are always equal )
Step-by-step explanation:
Answer:
angle one=122 because it is using the alternate interior angle theorem
angle 2=58 because it is using the consecutive interior angle theorem
hope this helps
have a good day :)
Step-by-step explanation:
remember consecutive=same sine 122 is on the same side of angle 2 just substract 180-122=58
since 122 is on the opposite side of angle 1 it's going to be alternate something so since it's on the inside its going to be alternate interior angle

You and your friends are starting a t-shirt business. The company you buy t-shirts from charges you $3 for each shirt plus a one-time screen print set up fee of $50. After surveying other students, you are going to sell the shirts for 7 each
A. Will your company be successful if you sell 23 shirts
B. Will your company be successful if you sell 10 shirts
C. How many shirts will you need to break even
Answer:
Part A. Answer: The company will be successful selling 23 shirts.
Part B. Answer: The company will not be successful selling 10 shirts.
Part C. Answer: 13 shirts
Step-by-step explanation:
initial cost: $50
cost per shirt: $3
sale price per shirt: $7
number of shirts: x
The cost, y, of x shirts is
y = 3x + 50
Part A.
cost of 23 shirts
y = 3(23) + 50
y = 119
revenue from selling 23 shirts:
23 * $7 = $161
It costs $119 to make 23 shirts. They are sold for $161.
Part A. Answer: The company will be successful selling 23 shirts.
Part B.
cost of 10 shirts
y = 3(10) + 50
y = 80
revenue from selling 10 shirts:
10 * $7 = $70
It costs $80 to make 10 shirts. They are sold for $70.
Part B. Answer: The company will not be successful selling 10 shirts.
Part C.
To break even, the cost and the revenue must be equal.
Cost of x shirts: 3x + 50
Revenue from selling x shirts: 7x
7x = 3x + 50
4x = 50
x = 12.5
The break even point is 12.5 shirts. Since the number of shirts sold must be a whole number, the break even number is 13.
Part C. Answer: 13 shirts.

Which of the following theorems verifies that AHIJE AKLM? H K M ОА. НА O O O B. LA O C. HL O D. AA
===================================
Explanation:
HA = hypotenuse angle
The tickmarks tell us that the hypotenuse IJ is the same length as the hypotenuse LM. So that's the "hypotenuse" portion of "HA".
The "angle" portion refers to the acute angles HIJ and KLM being the same measure, as shown by the curved arc marking. We aren't referring to the right angles because the HA theorem can only be used for right triangles, so that means the right angle is already built into it (and we can ignore the right angles).
Notice how HA is a special case of AAS.
What is the volume of the cylinder shown? Use 3.14 for pi. 4cm is the radius and 9cm is the height.
Answer:
The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04
Step-by-step explanation:
Answer:
Volume - 452.16 cm
Step-by-step explanation:
First we need to find the area of the circle.
Area of a circle - (3.14)r^2
Insert the radius in the formula -
(3.14) (4)^2
3.14 x 16
50.24 is the area of the circle
Now, we have to multiply this value by the height of the cylinder in order to find the volume.
50.24 x 9 = 452.16 cm

Write an equation of the line in slope intercept form given the information below slope=-4 point=(2,-4)
Answer:
y=-4x+4
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=-4(x-2)
y+4=-4(x-2)
y=-4x+8-4
y=-4x+4
A slope of a line is the change in y coordinate with respect to the change in x coordinate. The equation of the line in slope intercept form which is passing through (2,-4) is -4x +7.
What is the slope of a line?A slope of a line is the change in y coordinate with respect to the change in x coordinate. The equation of a line in slope intercept form is given by
y = mx + c.
Given the slope of the line, m=-4. Also, the point through which the line is passing,
(x₁ ,y₁) =(2,-4)
Since the equation of the line in the slope-intercept form of the line is given by
y = mx +c
Since, the above line is passing through (2, -4) and the slope is -4.
Therefore,-4 = -4(2) + c⇒ -4 = -8 + c⇒ -1 +8 = c⇒ c = 7
Substitute the value of m and c in the equation
y = mx + c
⇒ y = mx + c
⇒ y = -4x +7
Therefore, the equation of line in slope intercept form which is passing through (2, -4) is y = -4x +7.

a store has 9 blue hats and 7 red hats for sale write the ratio of blue hats to all the hats
Answer:
9 : 7, or 9/16 to 7/16
Step-by-step explanation:
We know that there are 9 blue hats.
We know there are 7 red hats.
This is a 9 : 7 ratio.
In fraction form, we must find the total ratio, use that as the denominator, then take the seperate amounts, such as bluei adn red hats, and use that as the numerator:
9+7=denominator
denominator = 16
Blue hats = 9
Ratio of red = 9/16
Red hats = 7
Ratio of red = 7/16

Answer:
Step-by-step explanation:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] where h and k are the center of the circle and r is the radius. Our center is located at (0, 1), so h = 0 and k = 1. Going from the center straight up of down we have to move 2 units to get to a point on the outside of the circle, so r = 2. Filling in our equation:
[tex](x-0)^2+(y-1)^2=2^2[/tex] which simplifies a bit to
[tex]x^2+(y-1)^2=4[/tex]
