How do I write an equation that would allow someone to find the value of R
Ivahew [28]

Answer:

R+239=3501

Step-by-step explanation:

Add the three 1,167 values together and you get 3,501. Then, because we know a portion of the three blocks is equal to 239, add it so when we solve for R, 239 is subtracted from the total.

As for solving it,

Subtract 239 on both sides, and R is 3501-239 = <u>3262</u>

Tan 45=√2/n

n=√2

again

sin 45=√2/m

m=2

answer:<u> </u><u>m</u><u>=</u><u>2</u><u>,</u><u>n</u><u>=</u><u>√</u><u>2</u>

<u>2</u><u>.</u>

sin 45=x/3

x=3/√2=3√2/2

y=3√2/2

<u>a</u><u>n</u><u>s</u><u>:</u><u>x</u><u>=</u><u>3√2/2</u><u>,</u><u>y</u><u>=</u><u>3√2/</u><u>3</u>

Ben walks 25 miles from home to work. If he walks the first 5 miles in 1 hour, the second 5 miles in 1.4 hours, the third 5 mile
natka813 [3]

<u>Answer:</u>

The total time taken to complete 25 miles is 7.6 hours.

Solution:

Ben walks 5 miles in 1 hour,

Second 5 miles in 1.4 hours,

Third 5 miles in 1.7 hours,

Last 5 miles in 1.8 hours

So he walked total 20 miles in (1+1.4+1.7+1.8) hours = 5.9 hours = 6 hours (approximately)

So his average speed is \left(\frac{20}{6}\right) miles/hours = 3.33 miles/hours.  

i.e. he travels 3.3 miles in 1 hour,

Then, he travels 1 miles in \left(\frac{1}{3.3}\right) hours

Hence the total time he will take to walk 25 miles is \left(25 \times\left(\frac{1}{3.3}\right)\right) \text { hours }\Rightarrow \left(\frac{25}{3.3}\right) \text { hours } = 7.5757 hours

That is approximately 7.57 or 7.6 hours.

PLEASE HELP ASAP!!! ILL GIVE BRANLIEST *EXTRA POINTS* !! PLEASE DONT SKIP :(((
mezya [45]

Answer:

92.5 centimeters.

Step-by-step explanation:

The one-meter snake showed up as 2 cm in the developed photo. Since there are 100 centimeters in a meter, you subtract the length of the snake in centimeters by the length it shows up in the picture. 100-2 is 88, so that would be the difference. To find the length of the wall, you add the difference to how it showed up in the picture. 88+4.5=92.5.
