Answer:

A cyclist can travel 18 kilometres in 1.5 hours.

Step-by-step explanation:

The ratio for the cyclist's speed is 12 km/1 hr. If I were to find the ratio for kilometres per 1.5 hour, I would need to multiply the denominator of 1 (aka 1 hour) by 1.5 to get (1.5 hours). Whatever you do to the bottom, you have to do to the top. So I multiply the numerator of 12 (12 km) by 1.5 to get 18 km.

12 km/1 hr → 18 km/1.5 hrs

Which algebraic expression is equivalent to the expression below?

JulijaS [17]

Step-by-step explanation:

7(4x + 9) - 4

= (7 × 4x) + (7 × 9) - 4

= 28x + 63 - 4

= 28x + 59

So, 7(4x + 9) - 4 is equivalent to 28x + 59 (D)

Which fraction is represented by point A on the number line?

Akimi4 [234]

This would be a lot easier with the figure.

Four equal spaces means quarters.

A is 1 mark to the left of 0, so 1/4 to the left of 0. That's -1/4

Answer: Negative one-fourth

Chance bought a surf board for 249. Now it's on sale for 221.10. Find the percent of the discount

Masteriza [31]

Answer:

Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.

Solution:

Step 1:

Bought price= RS.249

Sale price=RS.221.10

Step 2:

Discount = bought price - sales price

Discount = 249 - 221.10

Discount = 27.9

Step 3:

Discount Percent = $\frac{\text {Discount}}{M R P} \times 100$

Substitute the value for Discount which we found in step 2 in the above formulae

Discount Percent = $\frac{27.9}{249} \times 100$

On simplification, we get

$\frac{27.9}{249} \times 100$

Discount Percent = 11.20%

Result:

Hence from the given data, we got the discount percent is 11.20%
