Mr. Richards purchased 8 T-shirts for the volleyball team. The total cost of the T-shirts was $70.56. How much did each shirt cost?
Answer:
$8.82
Step-by-step explanation:
$70.56÷8 =$8.82 total
Answer:
$8.82
Step-by-step explanation:
The total cost of the T-shirts was 70.56. Each T-shirt is equal in money, so what you need to do is divide the total cost by the number of T-shirts.
70.56 / 8 = 8.82
Each T-shirt cost $8.82

1 2/4 = 1 1/2 = 150%
1 3/4 = 175%
Rhombus ABCD has side lengths of (6x + 4) inches, (4y + 10) inches, (8x − 14) inches, and (7y − 26) inches. The diagonals are 80 inches and 84 inches and intersect forming an angle of (8z + 2)°.
Answer:
x = 9, y = 12, z = 11
Step-by-step explanation:
A rhombus is a quadrilateral (has four sides and four angles) with four equal sides. Opposite sides of a rhombus are parallel to each other and the diagonals bisect each other at right angles i.e. 90°.
Given the rhombus ABCD:
(6x + 4) = (4y + 10) = (8x − 14) = (7y − 26) [the sides of a rhombus are equal].
Hence; 6x + 4 = 8x - 14
8x - 6x = 14 + 4
2x = 18
x = 9
Therefore the side length = 6x + 4 = 6(9) + 4 = 58 inches
Also: 4y + 10 = 7y - 26
7y - 4y = 10 + 26
3y = 36
y = 12
(8z + 2) = 90° (diagonals of a rhombus bisect each other)
8z + 2 = 90
8z = 90 - 2
8z = 88
z = 11
Please can someone help I’m crying myself out here please I don’t understand this I’m going to fail if I don’t do this please help for gods sake!
Answer:
Step-by-step explanation:
in right trigons with a 45 degree angle, a side length of x will mean the hypotenuse is [tex]x\sqrt{2}[/tex].
In right trigons with a 30 or 60 degree angle, if the shortest side is of length x, the longer side would be [tex]x\sqrt{3}[/tex] and the hypotenuse would be 2x.
Answer:
7√2
Step-by-step explanation:
*Note: this is only for the first question
So the picture at the bottom shows the ratio of the sides of a triangle with the angles of 45 degrees, 45 degrees, and 90 degrees.
In the image, they give you the side length that corresponds to a in the picture.
This means that to find the length of the hypotenuse, all you have to do is multiply 7 by the square root of 2

Solve this system by substitution 7x-y=3
y=x+3
Answer:
7x-y=3 (1)
y=x+3 (2)
Replace y = x + 3 in (1) => 7x- (x + 3) = 3
=> 6x-3 = 3 => x = 1 => instead of (2) => y = 4
So: x = 1, y = 4 is the solution of the system of equations

Sewing patterns recommend buying extra fabric in case of mistakes. Jessica bought 6 yards of fabric, plus 15% extra fabric.
Derek bought 5 yards of fabric, plus 30% extra. Who bought more fabric? How much more?
Answer:
Jessica bought more fabric
Step-by-step explanation:
15% of 6 is 0.9 and 30% of 5 is 1.5 so 6+0.9 = 6.9 and 5+1.5 = 6.5 so Jessica bought 0.4 yards more than Derek.
Jenny has $1,200 in her savings account. If the bank pays 3% interest per year on savings, how much interest does she earn in one year? A.$36 B.$360 C.$3.60 D.$3600
Given:
Principal value = $1200
Rate of interest = 3% per year
To find:
The interest earned by Jenny in one year.
Solution:
Formula of interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is rate of interest and t is time.
We have, P = 1200, r = 3, t=1. Putting these values, we get
[tex]I=\dfrac{1200\times 3\times 1}{100}[/tex]
[tex]I=\dfrac{3600}{100}[/tex]
[tex]I=36[/tex]
The interest earned by Jenny in one year is $36.
Therefore, the correct option is A.
A farmer raises sheep. The number of sheep in his flock changes from year to year. The number can be represented by the equation S=24(1.05)t where S is the total number of sheep in his flock and t is the number of years since he first started raising sheep. Which statement best explains the change in the number of sheep?
Answer:
It increases by 5% each year
Step-by-step explanation:
The function, S=24(1.05)t, models change in the Number of sheep over time, t.
The function represents an exponential growth model:
The function could be rewritten in the general form ;
y = Ab^x
y = number of comocafter t years
b = increase in initial amount ; b = (1 + x)
Comparing the function :
b = 1.05
b = 1 + r ; where r = rate
1.05 = 1 + r
r = 1.05 - 1
r = 0.05 = (0.05 * 100%). = 5%
It increases by 5% each year
