Answer:
$550.80
Step-by-step explanation:
Value of concrete used = volume of the prism x cost per cubic foot
volume of the prism = base area x height
the base is in the shape of a triangle
Area of a triangle = (1/2) x base x height = 1/2 x 6 x 6 = 18
Volume of the prism = 18 x 10.2 = 183.6 ft^3
183.6 x 3 = $550.80

It will take
gallons to fill the tank
Answer:
it will take 3 5/8 of gas to fill the tank
Step-by-step explanation:
14 1/2 - 10 7/8 can be re-written using improper fractions
29/2 - 87/8 We need a common denominator, which is 8

what is the value of x? 5 60 30 marking brainliest and giving thanks to all!!!
this is 90 60 30 formula for example
90 meet 2x
30 meet x
and
60 meet x√3
so 90 meet 5
30 meet 5/2=2.5
and 60 meet 2.5√3
so the answer is 2.5
Answer:
2.5
Step-by-step explanation:
[tex]\sin 30\degree = \frac{x}{5}\\\therefore x = 5\sin 30\degree\\\therefore x = 5 \times \frac{1}{2}\\\therefore x = 2.5[/tex]

find the ratio of 2500g to 35kg
35kg - 3500g
3500g - 2500g
= 1000g
Answer:
1 : 14
Step-by-step explanation:
The measures must have the same units, that is both g or Kg
2500 g : 35 Kg
= 2500 g : 35000 g ( 1 Kg = 1000 g )
Divide both parts by 100
= 25 : 350 ( divide both parts by 25 )
= 1 : 14

Simplify the radical expression 3√5+6√45
Answer:
21[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying [tex]\sqrt{45}[/tex]
= [tex]\sqrt{9(5)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{5}[/tex] = 3[tex]\sqrt{5}[/tex]
Then
3[tex]\sqrt{5}[/tex] + 6[tex]\sqrt{45}[/tex]
= 3[tex]\sqrt{5}[/tex] + 6(3[tex]\sqrt{5}[/tex] )
= 3[tex]\sqrt{5}[/tex] + 18[tex]\sqrt{5}[/tex]
= 21[tex]\sqrt{5}[/tex]
Answer:
[tex]21\sqrt{5}[/tex]
Step-by-step explanation:
Pull terms out from under the radical, assuming positive real numbers.

John and George together raked g of the yard. John 7. raked of that amount. What part of the yard did John rake?
Answer:
7/32
Step-by-step explanation:
John and George together raked 7/8 of the yard. John raked 3/4 of that amount. What part of the yard did john rake?
Proportion of the yard Jake raked = 7/8 x 3/4 = 21/32
Portion of the yard Jake raked = 21/32 - 7/8 = 7/32
Theresa had her hair cut to a length of 10 inches. If her hair grows at a rate of 0.02 inch per day, which equation represents the length (L) of Theresa’s hair, in inches, after d days?
d=0.2+10Ld is equal to 0 point 2 plus 10 liters
d=10+0.2Ld is equal to 10 plus 0 point 2 liters
L=0.2+10dcap l is equal to 0 point 2 plus 10 d
L=10+0.2dcap l is equal to 10 plus 0 point 2 d
Answer:
L = 0.02d + 10
Step-by-step explanation:
The hair starts at 10 inches long.
L = 10
Now we add 0.02 inches in length per day.
In 1 day, it grows 0.02 inches.
In 2 days, it grows 0.02 * 2 inches.
In d days, it grows 0.02d inches.
Now we add the starting length, 10, and the growth per day, 0.02d, to get:
L = 0.02d + 10

question 4, plz help ( radius is 6.8)
Answer:
A) 145.3 cm^2
Step-by-step explanation:
The formula for the area of a circle is A = π r^2
So to find the area we would plug the radius of 6.8 into the formula
Area = π (6.8)^2
Area = (3.14) (6.8)^2
Area = 145.27
Area = 145.3

Solve for a side in right triangles
I don’t know how to do this so please someone teach me how to do this?? I need help here!
Answer:
2.33
Step-by-step explanation:
imagine a circle. its center is A, and it goes through B, so its radius is AB.
then it is important to know that the sum of all the angles in a triangle is 180 degrees.
one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.
more back to our circle.
in this circle the line CB is the sine of the angle at A multiplied by the radius.
and AC is the cosine of the angle at A multiplied by the radius.
we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).
=> CB = sin(A)×AB
AC = cos(A)×AB
=> 5 = sin(65)×AB
=> AB = 5 / sin(65)
=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =
= 5 × cot(65) = 2.33
Trisha's favourite song is 2 1/2 minutes. There is a drum solo that begins one third of the way into the song and last for 24 seconds. How many seconds does the drum solo end
Answer:
74 seconds or1 minute 14 secondsStep-by-step explanation:
The drum solo begins a third of the way into the song which lasts 2.5 minutes.
The drum solo therefore starts at:
= 2.5 * 1/3
= 0.83 minutes
Translate that to seconds by multiplying by 60:
= 0.83 * 60
= 50 seconds
Solo begins at 50 seconds in and lasts for 24 seconds:
= 50 + 24
= 74 seconds or
= 1 minute 14 seconds

Find the surface area of the cone. Round your answer to the nearest tenth.
The surface area is
30
m².
9514 1404 393
Answer:
113.1 m²
Step-by-step explanation:
The surface area of the cone is ...
SA = πr(r +s) . . . . . . where r is the radius and s is the slant height
SA = π(4 m)(4 m + 5 m) = 36π m² ≈ 113.1 m²
The surface area is about 113.1 m².
