Answer:

It is 8

Step-by-step explanation:

you would do 13-0.75(12)+8(1/2) and that would equal 8.

Answer:

8

Step-by-step explanation:

substitute w = 12 and x = [tex]\frac{1}{2}[/tex] into the expression

13 - 0.75(12) + 8([tex]\frac{1}{2}[/tex] )

= 13 - 9 + 4

= 4 + 4

= 8

Explanation:

Use the cosine ratio to get the following,

cos(angle) = adjacent/hypotenuse

cos(71) = 20/x

x*cos(71) = 20

x = 20/cos(71)

x = 61.431 approximately

x = 61.4

Notes:

Answer:

x ≈ 61.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{20}{x}[/tex] ( multiply both sides by x )

x × cos71° = 20 ( divide both sides by cos71° )

x = [tex]\frac{20}{cos71}[/tex] ≈ 61.4 ( to the nearest tenth )

The percent of the original price after markup is 98%

Given the following parameters

If during a sale, a store offered a 15% discount on a tablet, the new price after discount will be:

New price = 0.85 * 460

If the tablet computer was marked up by 15% after the discount, then the price after the markup is given as:

To get the required percent;

x% of 460 = 450
x% = 450/460

x% = 0.978

x = 98%

Hence the percent of the original price after markup is 98%

Step-by-step explanation:

By Linear Pair Theorem,

110⁰ + 5x⁰ = 180⁰

5x⁰ = 70⁰ ------- (1)

x⁰ = 14⁰

We know that adding the angles of the triangle lying on the same side, equals the opposite exterior angle, i.e.,

5x⁰ + 40⁰ = 2y⁰

From 1,

70⁰ + 40⁰ = 2y⁰

110⁰ = 2y⁰

y⁰ = 55⁰

Answer:

Step-by-step explanation:

Step-by-step explanation:

let's aim for the slope intercept form of the line equation :

y = ax +b

a is the slope, b is the y intercept (the y value when x = 0).

the slope of a line is the ratio "y coordinate change / x coordinate change" when going from one point to another on the line.

I cannot draw here, but you know, what the slope triangle means : you draw a vertical line straight down from (2, 150) and a straight horizontal line left from (4, 130). where these lines cross, you have the third point of that triangle.

anyway, we don't need the drawn triangle to find the coordinate changes to calculate the slope.

between these 2 points

x changes by +2 (from 2 to 4)

y changes by -20 (from 150 to 130)

so, the slope is -20/+2 = -10

that brings the generic equation to

y = -10x + b

for b we simply use the coordinates of one of the points (I go for (2, 150)) and solve for b :

150 = -10×2 + b = -20 + b

b = 170

so, the full line equation is

y = -10x + 170

Answer:

5.5 hours i think

Step-by-step explanation:

64 x 3 = 192 for the first day

544 - 192 = 352

64 x 5.5 = 352

therefor your anwser is 5.5

The time taken by Vijay's family to drive on the second day is 5.5 hours.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

The time is calculated as:-

For 3 hours of driving at an average speed of 64 miles per hour, the distance covered is,

d = 64 x 3 = 192miles

Miles remaining for the second day is,

544 - 192 = 352 miles

Time taken to cover 352 miles second day is,

T = 352 / 64 = 5.5 hours

Answer:

x=20

Step-by-step explanation:

To find x use the fact that all triangle's angles sum to 180. This means that if you add all of the angles together, they will always equal 180 degrees. So, create an equation to represent this.

2x+65+75=180

2x+140=180

2x=40

x=20

This means that the missing angle is 40 degrees.

When both facets are turned on, they fill 1%2F4 of the bathtub volume per minute.

When only cold facet is turned on, it fills 1%2F12 of the bathtub volume per minute.

It means that the contribution of the hot facet is the difference 1%2F4 - 1%2F12 = 3%2F12 - 1%2F12 = 2%2F12 = 1%2F6 of the bathtub volume per minute.

Therefore, it will take 6 minutes for the hot facet to fill the bathtub working alone.

Step-by-step explanation:

You can do this with a proportion. It takes 5/6 of a gallon to paint 1 wall and you want to know how much of a wall can you paint with 1/2 gallon. So set up the proportion:

5/6 / 1 = 1/2 / x

cross multiplying gets you 5/6x = 1/2

multiply by the reciprocal of 5/6 to isolate x - which is 6/5. 1/2 times 6/5 = 3/5
