the volume of a cuboid is 480cm cube,it's breadth and height are 8cm are 6cm respectively find its length​

Answers

Considering the volume of a cube is length × breath × height, we are going to have to use an equation to find the length.

V = l × b × h

480cm³ = L × 8 × 6

Make L the subject.

480 = L × 8 × 6
⁴⁸⁰/₈×₆ = L
10cm = L

Therefore length = 10cm

A new car sells for $29,250. It straight line depreciates in 13 years. What is the slope of the straight line depreciation equation?

Answers

Answer:

The slope of the straight line is -2,250

Step-by-step explanation:

Given:

The cost of a new car = $29,250

It depreciates in 13 years, it means the value of the zero in 13 years.

Therefore, the value of the car decreasing which is negative.

Let's take "x" is the amount decreasing by years, which represents the slope.

29250 = -13x

Dividing by -13 both sides, we get

-13/-13 x = 29250/-13

x = -2,250

Therefore, slope of the straight line is -2,250

Hope this will helpful.

Thank you.

Find the GCF of the terms of the polynomial.26x² + 34x^4

A. x²
B. 26x²
C. 2x^4
D. 2x²

Answers

the answer choice is d because the the greatest exponent is 4 but you cant take 4 exponents out of 2 . Both numbers are divisible by 2 x^(2) which would make the answer 13+17 x^(2) 
26x²: 13 · 2 · x · x
34x⁴: 17 · 2 · x · x

GCF: 2x²

26x² + 34⁴
2x²(13) + 2x²(17x²)
2x²(13 + 17x²)

The answer is equal to D.

the spoke of a wheel reaches from the center of the wheel to its rim. If the circumstances of the rim of the wheel is 42 inches, how long is each spoke?

Answers

The spoke of the wheel serves as the radius of the circle. 
To solve for the circumference of the circle, we use this formula:

C = 2πr
42 inches = 2 * 3.14 * r
42 inches = 6.28 * r
42 inches / 6.28 = r 
6.69 inches = r

The length of each spoke is 6.69 inches.
