Answer:

38.485(correct to 5 significant figure)/ 12.25π

Step-by-step explanation:

$\pi(7 {}^{2} )( \frac{90degree}{360deree} )$

$= \pi(49)( \frac{1}{4} )$

=38.485(cor. to 5 sig.fig.)/ 12.25π

to find arc length of sector,we need to π(radius²)(sector's degree divided by 360 degree)

In triangle STU, u2 = s2 + t2. Triangle STU has sides s, t, u opposite to the corresponding vertices S, T, U Which equation is t

wlad13 [49]

Answer:
<span>The measure of angle SUT is equal to 90 degrees
</span>
Explanation:
The Pythagorean theorem states that:
"In any right-angled triangle, the square of the hypotenuse is equal to the sum of squares of the other two sides"
In other words:
(hypotenuse)² = (first side)² + (second side)²

Now, for the given, we have:
u² = s² + t²
This means that the given triangle UST is a right-angled triangle and that side "u" is its hypotenuse.

According to the given, the angle opposite to side "u" is angle U. This means that angle U is the right-angle in this triangle.

Based on the above:
angle U = 90°
angle S + angle T = 180 - 90 = 90°

Now, comparing our deductions to the given choices, we can conclude that the correct choice is:
The measure of angle SUT is equal to 90 degrees

Hope this helps :)

You have 20 quarters and then find 40% more and then spend 75% how much money do you have left

kirza4 [7]

You have $1.75 left

Step-by-step explanation:

Given,

Number of quarters already have = 20

Percent of quarters found = 40% of already have

Number of quarters found = $\frac{40}{100}*20$

Number of quarters found = $\frac{800}{100}$

Number of quarters found = 8

New total = 20+8 = 28 quarters

Percent of quarters spent = 75%

Number of quarters spent = $\frac{75}{100}*28$

Number of quarters spent = $\frac{2100}{100}$

Number of quarters spent = 21

Quarters left = 28-21 = 7

1 quarter = 25 cents

7 quarters = 25*7 = 175 cents

$1 = 100 cents

175 cents = $\frac{175}{100}=\$1.75$

You have $1.75 left

sineoko [7]

Answer:

the daily fee =33 dollars

and the mileage charge.=0.35

Step-by-step explanation:

let d: be daily fee and m for mileage

cost of rental =(d*number of days)+ (m*number of mileage)

her first trip: 4d+440m=286

her second trip: 3d+190m=165.5

solve by addition and elimination

4d+440m=286 ⇒ multiply by 3 ⇒12d +1320m=(3)286

3d+190m=165.5⇒ multiply by 4⇒12d+190(4)m=4(165.5)

12d+1320m=858

12d+760m=662

subtract two equation to eliminate d

12d+1320m-12d-760m=858-662

560m=196

m=7/20=0.35 for on mileage

d: 4d+440m=286

4d=286-440(0.35)

d=(286-154)/4 33 dollars
