Reese went cycling in the morning .The ratio of her distance in miles to the length of time in minutes was 15:60 tease concluded

rodikova [14]

Answer:

No, she is not correct as her speed is 0.25 miles per minute.

Step-by-step explanation:

Given:

Ratio of distance to time taken is 15 : 60.

Distance is in miles and length of time is in minutes.

We know that, average speed is given as the ratio of the distance traveled and the length of the time taken.

So, the ratio above is nothing but the average speed of Reese for cycling.

Thus, average speed of Reese is given as:

$\textrm{Average speed}=\frac{Distance}{Time}\\\\\textrm{Average speed}=\frac{15}{60}\ miles\ per\ min\\\\\textrm{Average speed}=\frac{1}{4} = 0.25\ miles\ per\ min$

Therefore, the average speed of Reese is 0.25 miles per minute which is not equal to the one mentioned by Reese as 4 miles per minute.

So, Reese conclusion of her average speed is incorrect. It's not 4 but the reciprocal of 4 which is 0.25 miles per minute.

What are the values of x, y, and z?

hoa [83]

<h3>To find value of x</h3>

Formula applied:

Exterior angle=Sum of interior angles

Answer:

x=66⁰+45⁰

x=111⁰✔

<h3 />

<h3>To find value of z:</h3>

Formula applied:

Exterior angle=Sum of interior angles

Answer:

119⁰=43⁰+z⁰

119⁰-43⁰=z⁰

z⁰=76⁰✔

<h3>To find value of y:</h3>

∠1+66⁰=180⁰(L.P)

∠1=180⁰-66⁰

∠1=114⁰

Formula used:

Sum of angles of a triangle =180⁰

Answer:

∠ 1+30⁰+y⁰=180⁰

114⁰+30⁰+y⁰=180⁰

y⁰=180⁰-144⁰

y⁰=36⁰✔

I don't get it can u help me??

andrew-mc [135]

Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.

Hope this helps! Let me know if you have any more questions!
