9 ft. 15 ft The volume of the figure is cubic feet. 15 ft. 15 ft
Answer:
4,050 cubic feet
Step-by-step explanation:
The figure is made up of a square pyramid and cube
Therefore:
Volume of the figure = volume of the square pyramid + volume of the cube
✔️Volume of the square pyramid = ⅓*a²h
a = 15 ft
h = 9 ft
Volume of square pyramid = ⅓*15²*9 = 675 ft³
✔️Volume of the cube = s³
s = 15 ft
Volume of the cube = 15³ = 3,375 ft³
✔️Volume of the figure = 675 + 3,375 = 4,050 cubic feet
Four families went out for lunch. The total food bill came to $220. The families also left a $30 tip for the waitress.
If each family spent the same amount, about how much did each family spend on dinner? Complete the explanation on how you found your answer.
First, add $
and $30 to find the total bill.
$
is between $
and $
, but closer to $
. $
× 4 = $240, so each family spent about $
on lunch.
$250 Dollars.
All 4 families together spent 1,000 Dollars.
ALL FAMILIES SPEND 1000 DOLLARS
$ 250 DOLLARS

Which of the following has a graph that is a straight line?
Equation 1: y = 4x3 + 6
Equation 2: y = 5x − 4.5
Equation 3: y2 = x − 1
Equation 4: y = 2x2 + 6
Answer:
Equation 2: y= 5x - 4.5
Step-by-step explanation:
This is a correct linear function. I would think this equation is linear because it goes by the f(x)=mx+b formula.
Answer: It would be equation B!

option
A.
A.40.82 in
is your answer.
Step-by-step explanation:
the formula for the circumference of a circle for just the radius is
2r(pie)
so just insert 6.5 for r
2(6.5)(pie)
40.82

what the total area of a rectangular prism with a hight of 17feet a width of 12 feet and a thickness of 10 feet ?
Answer:
988ft^2
Step-by-step explanation:
Total area of a rectangular prism = 2(lw+wh+lh)
length l = 17feet
width w = 12feet
thickness = 10feet
TSA = 2(17(12)+17(10) + 12(10))
TSA = 2(204+170+120)
TSA = 2(494)
TSA = 988ft^2
Hence the total surface area is 988ft^2
solve for x in the diagram below
What is the value of x in simplest radical form?
Answer:
x = 85
Step-by-step explanation:
Because this is a right triangle, we can use the Pythagorean Theorem:
a² + b² = c²
Where c is the hypotenuse, or the longest side. This is opposite to the right angle of the right triangle. So now you have:
84² + 13² = x²
7056 + 169 = x²
7225 = x²
√7225 = √x²
85 = x
x = 85
Algebra find the value of x in each figure .
Answer:
x= 54°
Step-by-step explanation:
43 + x - 7 = 90°
36 + x = 90°
x= 90-36
x= 54°
Answer:
54
Step-by-step explanation:
90-43 = 47
x-7 = 47
x=47+7
x = 54

is AB tangent to the circle?
Answer:
Yes, AB is tangent to the circle
Step-by-step explanation:
If AB is tangent to the circle, the triangle will be a right triangle, so if:
11.4² + 15.2² = 19²
129.96 + 231.04 = 361
361 = 361
so it is tangent

Find the measure of angle B in triangle ABC below.Explain
Answer:
B ≈ 76°
Step-by-step explanation:
∆ABC is a right triangle
Reference angle = B
AC = 8 units = Opposite
BC = 4 units = Adjacent
Thus, apply TOA:
Tan B = Opp/Adj
Tan B = 8/2
Tan B = 4
B = Tan^{-1}(4)
B ≈ 76°
cosA-sinA+1/cosA+sinA+1=1-sinA/cosA
Answer:
steps below
Step-by-step explanation:
(cosA-sinA+1) * cosA = cos²A - sinA cosA + cosA
= (1 - sin²A) - sinA cosA + cosA + sinA - sinA
= cosA + sinA + 1 - sinA cosA -sin²A - sinA ..Re-group
= (cosA + sinA + 1) - sinA (cosA + sinA + 1)
= (cosA + sinA + 1) * (1 - sinA)
(cosA-sinA+1) / (cosA + sinA + 1) = (1 - sinA) / cosA
