Step-by-step explanation:
9x8= 72
therefore 36 x 2 are the products
9 n^2 - 36n + 2 n -8
9 n( n-4) + 2( n- 4)
therefore the two factors are
( 9 n +2) ( n-4)
identify the scale factor
Answer:
4
Step-by-step explanation:
30*4=120 because 12=3*4 and 30*4 is basically 3*4*10, and since it's asking for the scale factor, we test to see if 12*4=48, which it does.

What is the volume of this cylinder?
Step-by-step explanation:
V=pi r^2h
V=3.14x3^2x7
=197.82
Answer:
V ≈ 198 m³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
Here diameter = 6, then radius r = 3 and h = 7 , then
V = 3.14 × 3² × 7 = 3.14 × 63 ≈ 198 m³ ( to the nearest whole number )
54 divided by 7 is???
[tex] \implies \sf \boxed{ \sf7.71}[/tex]
The remainder is 5 when 54 is divided by 7.
What is Division?Division in mathematics is the process of dividing an amount into equal parts. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.
Given:
We have to divide 54 by 7.
So, the division is
7 | 54 | 7
49
-_____
5
Then, the remainder is 5 because we do not have number further and 5 is smaller than divisor.

A sidewalk is 15cm high, 30m wide and 60m long. The volume of concrete that was used to pour the sidewalk is
A. 270 m3
B. 2700 cm3
C. 27 m3
D. 270000 cm3
The volume of concrete that was used to pour the sidewalk is 270 cubic meters and this can be determined by using the formula of volume.
Given :
A sidewalk is 15cm high, 30m wide, and 60m long.
The following steps can be used in order to determine the volume of concrete that was used to pour the sidewalk:
Step 1 - The formula of volume can be used in order to determine the volume of concrete that was used to pour the sidewalk.
Step 2 - The formula of volume is given below:
[tex]\rm V = L\times W \times H[/tex]
where L is the length, W is the width, and H is the height.
Step 3 - Now, substitute the values of the known terms in the above formula.
[tex]\rm V = 60\times 30 \times \dfrac{15}{100}[/tex]
Step 4 - Simplify the above expression.
V = 270 cubic meters
Therefore, the correct option is A).

A rectangular poster has an area of 38 square feet. It is 4 3/4 feet wide at its base. What is the height of the poster? HELP I NEED ANSWERS QUICK
Answer:
8
Step-by-step explanation:
The formula for area is length x width or length x height, height and width mean the same thing in some problems such as this one. To find the height, you need to divide the area by the width. 38 divided by 4 3/4 = 8.

A triangular prism is 17 yards long and has a triangular face with a base of 12 yards and a height of 8 yards. The other two sides of the triangle are each 10 yards. What is the surface area of the triangular prism?
Answer:
640 yard²
Step-by-step explanation:
From the question,
The surface are of a triangular prism is given as
A = bh+2ls+lb.................. Equation 1
Where A = Surface area of the triangular prism, b = base of of the triangular face, h = height of the triangular face, l = length of the triangular prism, s = length of one of the other sides of the triangle
Given: l = 17 yards, b = 12 yards, h = 8 yards, s = 10 yards.
Substitute these values into equation 1
A = [(12×8)+(2×17×10)+(17×12)]
A = 96+340+204
A = 640 Yard²

A worker work for just 3 days in a one month and his 1 month salary is 4380 what is the 3 days pay ?
Answer:
$505.385
Step-by-step explanation:
Given that:
Worker's one month salary is 4380
The number of working days in the month is not given ; However the average number of working days in a month usually range from 22 to about 26 days
Lets assume the number of working days for the firm in question is 26 days
Daily salary will be calculated as :
Monthly salary / number of working days
4380 / 26
= 168.46153
3 days salary :
168.46153 * 3
= $505.385
Joe and Josh each want to buy a video game. Joe has $14 and saves $10 a
week. Josh has $26 and $7 a week. In how many weeks will they have the
same amount?
pls help and give a step by step explanation
Answer:
Number of week they have same amount = 4 week
Step-by-step explanation:
Given:
Amount Joe have = $14
Joe's saving per week = $10
Amount Josh have = $26
Josh saving per week = $7
Find:
Number of week they have same amount
Assume;
Number of week they have same amount = a
So,
(14 + 10a) = (26 + 7a)
3a = 12
a = 4
So,
Number of week they have same amount = 4 week
