Answer:
112 cm^2
Step-by-step explanation:
Area of a rhombus is equal to half of the product of the diagonals, so it is 14 * 2 * 8 / 2 = 14cm * 8cm = 112 cm^2.
Other point of view: It is the sum of areas of two triangles of area 14*8/2. So the area is 14*8.

If the length of an arc of measure 55 degrees is 3.87 inches find the circumference of the circle
Answers
Answer:
25.33 is the circumference of the circle
Step-by-step explanation:
Here, given the measure of the arc, we want to get the circumference of the circle
mathematically, the length of an arc can be calculated using the formula;
theta/360 * 2 * pi* r
where 2 * pi * r = circumference of the circle
theta is the angle subtended at the center which is 55 degrees in this case
Thus, we have ;
55/360 * 2 * pi * r = 3.87
2 * pi * r = (3.87 * 360)/55
2 * pi * r = 25.33 inches

50 hundredths = ______ thousandths equals?
Answers
Answer:
50/100 = 500/1000 or alternatively .50 = .500
Answer:
500
Step-by-step explanation:
50 hundredths written in standard form is 0.50 .
**Adding zeroes to the end of a decimal does not change the value of the number.
1 hundredth = 0.01
1 thousandth = 0.001
So, if there are 50 hundredths, how many thousandths would there be?
The difference between hundredths and thousandths are the placement of the decimal point and how many decimal places there are after it. Hundredths have 2, while thousandths have 3.
Back to the example, 1 hundredth = 10 thousandths:
0.01 = 0.010
If there are 50 hundredths, that would mean that there are 10 times more thousandths in the same number.
0.50 = 0.500
50 hundredths = 500 thousandths

113.04 ft³ is correct
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius and h the height )
There are 2 cones to be summed one with h = 7 , the other with h = 5
Thus
V = [tex]\frac{1}{3}[/tex] π × 3² × 7 + [tex]\frac{1}{3}[/tex]π × 3² × 5
= [tex]\frac{1}{3}[/tex] × 3.14 × 9 (7 + 5)
= 3.14 × 3 × 12

A rectangular prism has a base area 56 ft.² and a volume of 840 ft.³ the length of the base is longer than the width if the sum of the length and the width of the base is equal to the height of the pyramid what is the length of the base in feet
Answers
Answer:
The length of the base in feet is 8 ft.
Step-by-step explanation:
The volume V of the rectangular prism is given by
V = l × w × h
But Area, A = l × w
∴ V = A × h
Where A is the base area and h is the height
From the question
A = 56 ft.² and V = 840 ft.³
∴ 840 ft.³ = 56 ft.² × h
840 ft.³ / 56 ft.² = h
15 ft. = h
∴ h = 15 ft.
Hence, the height of the rectangular prism is 15 ft.
Also, from the question
the sum of the length and the width of the base is equal to the height
i.e l + w = h
where l is the length of the base and w is the width of the base
Then, l + w = 15 ------ (1)
Also, A = l × w
Then, 56 = l × w ------- (2)
From equation (1)
l + w = 15
Then, w = 15 - l ------- (3)
Substitute this into equation (2)
56 = l × w
56 = l × (15-l)
56 = 15l - l²
Then,
l²- 15l + 56 = 0
l² -8l -7l + 56 = 0
l(l - 8) -7(l - 8) = 0
(l - 7)(l - 8) = 0
l - 7 = 0 OR l - 8 = 0
∴ l = 7 OR l = 8
Substitute the values of l into equation (3)
w = 15 - l
when l = 7
w = 15 - 7
w = 8
and when l = 8
w = 15 - 8
w = 7
From the question, the length of the base is longer than the width
∴ l = 8 and w = 7
Hence, the length of the base in feet is 8 ft.

Celeste was selling meal tickets for the holiday program at her school. The cost of a dinner ticket is
$10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold;
however, she remembered that she was given 100 tickets and she collected $900.
The system of equations shown can be used to represent this situation:
S x + y = 100
(10x + 6y=900
5. What does the variable x represent in the system of equations? *
1 point
O A. The number of dinner tickets sold.
O B. The number of dessert tickets sold.
O C. The number of dollars collected for dinner tickets.
D. The number of dollars collected for dessert tickets.
O Other:
Answers
X is next to the number 10, so x would be the number of dinner tickets sold.
Rewrite x + y = 100 to x = 100-y
Now replace that in the 2nd equation:
10(100-y) + 6y = 900
Simplify:
1000 -10y + 6y = 900
Combine like terms:
1000 -4y = 900
Subtract 1000 from both sides
-4y = -100
Divide both sides by-4
Y = 25
Replace y in the first equation and solve for x
X + 25 = 100
X = 75
A) 75 dinner tickets were sold
B) 25 dessert tickets were sold
C) 75 x 10 = $750
D) 25 x 6 = $150

Answer: 3x+5, (3x+5)*3 and 5x+4x+15
Step-by-step explanation:
Answer: I think the first one is 3x+5 since it’s a triangle, just divide it by 3 for one side.
5- 3x+5(3) and (6x+10) +(3x+5)
6- they’re equivalent because if you multiply each value for the first equation by 3, you get the original equation, the second is equal at because 6x+10 is equal to 2 sides while 3x+5 is still equal to one, so adding thos together would still give you the original equation, I’m sorry if this is wrong.
