Just 6, 8, and 10 plz<br> thx
marshall27 [118]
6 - 15/40 = 0.375 = 37.5%
When looking to convert a decimal to a percent you move the decimal over two places so, 0.375 becomes 37.5 

8 - 70*1.2 = 80 

You see 100% is equal to 1.00 when multiplying/dividing. So 1.2 = 120%

10 - 48*0.25 = 12 and 12+48 = 60 So, 60.

Here, we use 0.25 because 100% - 75% = 25% or... 1.0 - 0.75 = 0.25

Find the angle between the given vectors to the nearest tenth of a degree. u = , v = (2 points)
Liono4ka [1.6K]

Answer:

<h2>3.6°</h2>

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Find the angle between the given vectors to the nearest tenth of a degree.

u = <8, 7>, v = <9, 7>

we will be using the formula below to calculate the angle between the two vectors;

u*v = |u||v| cos \theta

\theta is the angle between the two vectors.

u = 8i + 7j and v = 9i+7j

u*v = (8i + 7j )*(9i + 7j )

u*v = 8(9) + 7(7)

u*v = 72+49

u*v = 121

|u| = √8²+7²

|u| = √64+49

|u| = √113

|v| = √9²+7²

|v| = √81+49

|v| = √130

Substituting the values into the formula;

121= √113*√130 cos θ

cos θ = 121/121.20

cos θ = 0.998

θ = cos⁻¹0.998

θ = 3.6° (to nearest tenth)

Hence, the angle between the given vectors is 3.6°

Car Rentals rents cars and trucks for $25 and $30 a
Sladkaya [172]

Answer:let x be the number of cars, and 7-x be the number of trucks.

25x + 30(7-x) = 195

25x + 210-30x = 195

5x = 15

x = 3

So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks

4 Trucks were not rented.
