Answer:
15/100 x 20 = 3
Step-by-step explanation:
15 percent of 20 is 3.
Consider 15 out of 100 since a percent is always considered out of hundred.
15
___ x 20 =
100
First thing is first, we ALWAYS have to find what the percent is of and its of 20 fruits.
So 15/100 x 20 would be your equation
we can simplify
15
___ x 20 ------> 1 = 15
100 -----> 5 ___ x 1 = 3
5
To simplify we can divide by 20 on the denominator and the factor.
Footballs sell for $27.99 each at the Sports R' Us and for $21.59 each at the Fitness Depot. If the coach buys a dozen footballs, how much can he save by buying them at the Fitness Depot?
Answer:
He can save $76.8 by buying them at the Fitness Depot.
Step-by-step explanation:
If the coach buys a dozen footballs, it means that he buys 12 and first, you need to determine the cost of purchasing the 12 footballs at each store by multiplying the amount of footballs for the price at each store.
-Sports R' Us: $27.99*12=$335.88
-Fitness Depot: $21.59*12=$259.08
Then, you have to find the difference between the total cost at both places:
$335.88-$259.08=$76.8
According to this, the answer is that he can save $76.8 by buying them at the Fitness Depot.

In a child’s bank are 11 coins that have a value of $1.85. The coins are either quarters or dimes. How many coins are quarters?
Answer:
The child has 6 dimes and 5 quarters.
Step-by-step explanation:
Let q and d represent the number of quarters and of dimes respectively.
Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).
Multiply the 2nd equation by 100 to remove the decimal fractions:
25q + 10d = 185 (Equation C)
Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:
-10q - 10d = -110
25q + 10d = 185
--------------------------
15q = 75, and so q = 75/15 = 5.
According to Equation A, q + d = 11. Replacing q with 5, we get:
5 + d = 11, and so d = 6.
The child has 6 dimes and 5 quarters.
Answer: The amount of money in quarters is $1.75
Step-by-step explanation: There are 7 quarters. 25c+25c+25c+25c+25c+25c+25c=1.75

Define sedimentary rock.(1 point)
Sedimentary rock is a type of rock that is formed over long periods of time by the transformation of existing rock types. The original rock is subjected to large heats and pressures causing very large changes.
Sedimentary rock is a type of rock formed over long periods of time by the cooling and solidification of molten Earth material.
Sedimentary rock is a type of rock that is formed in a very short period of time by sudden violent volcanic eruptions into the ocean. The hot molten material becomes rock very quickly in the cool water.
Sedimentary rock is a type of rock that is formed over long periods of time by layers of silt building up on the floor of a body of water, which is then subjected to the immense weight of the ocean above it.

Three game tickets and four ride tickets cost $39. Five ride tickets cost $15. All game tickets cost the same and all ride tickets cost the same. What is the ratio of the cost of a game ticket to the cost of a ride ticket?
Answer: 3:1
Step-by-step explanation:
Let the cost of a game ticket be g.
Let the cost of a ride ticket be r.
The information given can be formed into an equation which will be:
3g + 4r = 39
Since Five ride tickets cost $15, the cost of each ride ticket will be:
= $15/5
= $3.
Therefore, 3g + 4r = 39
We put the value of r = $3 into the equation
3g + 4(3) = 39
3g + 12 = 39
3g = 39 - 12
3g = 27
g = 27/3
g = 9
The cost of a game ticket is $9
The ratio of the cost of a game ticket to the cost of a ride ticket will be:
= 9/3
= 3/1
= 3:1
The ratio is 3:1

find the area of ABCD
trapezoid ABCD ~ trapezoid EFGH
trapezoid ABCD: 20cm
trapezoid EFGH: 5cm
area of EFGH = 40 sq cm
Answer:
640 cm²
Step-by-step explanation:
The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths
Thus:
Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²
Area of Trapezoid ABCD = ? = x
Area of Trapezoid EFGH = 40 cm²
AB = 20 cm
EF = 5 cm
Substitute
x:40 = 20²:5²
x/40 = 400/25
x/40 = 16
Cross multiply
x = 16*40
x = 640
Area of trapezoid ABCD = 640 cm²
Simplify.
(-x²+2x-3)+(7x²+6x+5)
Answer:
6x² + 8x + 2
Step-by-step explanation:
(-x² + 2x - 3) + (7x² + 6x + 5 ) = ?
-x² + 2x - 3 + 7x² + 6x + 5 = ?
-x² + 7x² + 2x + 6x - 3 + 5 = ?
? = 6x² + 8x +2

PLEASE HELP ME WITH THIS QUESRTION I KEEP GETTING THIS WRONG
angle t = ___?
Answer:
[tex]141^{\circ}[/tex]
Step-by-step explanation:
The quadrilateral in the image is a cyclic quadrilateral, because it is circumscribed by a circle. In all cyclic quadrilaterals, each pair of opposite sides are supplementary (add up to 180 degrees). Therefore, we have the following equation:
[tex]m\angle T+39=180,\\m\angle T=\boxed{141^{\circ}}[/tex]
Two functions, A and B, are described as follows: Function A y = 8x + 3 Function B The rate of change is 1 and the y-intercepted is 4. How much more is the rate of change of Function A than the slope of Function B?
Answer:
7
Step-by-step explanation:
Expressing Both equations in the slope intercept format : y = mx + c
Function A :
y = 8x + 3
Where, slope = 8 ; intercept = 3
Function B:
y = x - 4
Note ;
Rate of change = slope
Rate of change or slope of function A = 8
Slope of function B = 1
Difference = 8 - 1 = 7

Jun and Deron are applying for the summer job at a local restaurant. The probability that Jun gets the job is 0.7, the probability that Deron gets the job is 0.4, the probability that at least one of them gets hired is 0.9. What is the probability that both Jun and Deron get hired
Answer:
The probability that both Jun and Deron get hired=0.2
Step-by-step explanation:
Let
A=Jun
B=Deron
We are given that
The probability that Jun gets the job, P(A)=0.7
The probability that Deron gets the job, P(B)=0.4
The probability that at least one of them gets hired, [tex]P(A\cup B)=0.9[/tex]
We have to find the probability that both Jun and Deron get hired.
We know that
[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
Using the formula
[tex]0.9=0.7+0.4-P(A\cap B)[/tex]
[tex]P(A\cap B)=1.1-0.9[/tex]
[tex]P(A\cap B)=0.2[/tex]
Hence, the probability that both Jun and Deron get hired=0.2
Honon spent 3 1/4 hours on homework while Sequoia spent 2 5/6 hours on homework. How much more time did Honon spend on homework than Sequoia
Answer:
5/12 hours
Step-by-step explanation:
Honon = 3 1/4 hours
Sequoia = 2 5/6 hours
How much more time did Honon spend on homework than Sequoia
= number of hours Honon spent - number of hours Sequoia spent
= 3 1/4 hours - 2 5/6 hours
= 13/4 - 17/6
= (39-34) /12
= 5/12 hours
The perimeter of a right -angled triangle is 72 cm . Its side are in the ratio 3 : 4: 5.Work out the longest length of the triangle.
Answer:
The longest length is 30 cm
Step-by-step explanation:
Mathematically, the perimeter of a triangle is simply the sum of the lengths of its three sides
So, what we have to do here is divide the perimeter in the given ratio to get the side lengths
since 5 is the biggest of the numbers in the ratio, it represents the largest length value
so we have this as;
(3 + 4 + 5) = 12
So that would be;
5/12 * 72
= 5 * 6 = 30
