Use Pythagorean theorem to find area. Help!! ;-;

Answers

Answer:

area=135

Step-by-step explanation:

Pythagorean theorem: a^2+b^2=c^2

8^2+b^2=17^2

64+b^2=289

b^2=225

b=15

15 is the missing side length

The area is comprised of two triangle (which make one rectangle) and one rectangle (1 unit by 15).

area= bh(of a triangle) + bh(of the middle rectangle

area=8(15)+1(15)

area=135

Answers

Answer:

Right angle

Step-by-step explanation:

Right angle and Acute angle

Required

Which is greater

An acute angle has its angles less than 90 degrees while a right angle has its angle to be exactly 90 degrees

Take for instance:

[tex]Acute\ Angle = 80[/tex]

[tex]Right\ Angle = 90[/tex]

By comparison: 90 > 80

So, right angle is greater.

"What is Limit of h (x) as x approaches 10 plus?"

Answers

As x → 10 from above, h(x) is steadily approaching 18.5.

According to the table, the limit of h (x) as x approaches 10 plus is 18.5

How to determine the limit value?

From the table, the value of the function at x = 10 is:

h(10) = undefined

As x exceeds x = 10, the function values become:

h(x+) = 18.5......

When approximated, we have:

h(x+) = 18.5

Hence, the limit of h (x) as x approaches 10 plus is 18.5

She would have to work at least 12 hours.

At Chili’s, she would be paid 11.75x + 33 per week, with x being the number of hours she worked.

At the Cheesecake Factory, Giselle would be paid 14.50x per week, with x being how many hours she worked.

We want to know how many hours Gisele would have to work for her pay at the Cheesecake Factory to be more than her pay at Chili’s

The inequality 11.75x + 33 < 14.50x is what has to be set up to solve the problem. At how many hours will the pay on the left be less than the pay on the right?

11.75x + 33 < 14.50x
33 < 2.75x
12 < x

So Giselle has to work greater 12 hours a week for her to make more money at the Cheesecake Factory.

b. 500
d. 700
a. 400

Answers

Answer:

The porter charges Rs 300 at this rate.

Step-by-step explanation:

We solve this question by proportions, using rule of three.

75 Rs - 4 km - 50 kg

x Rs - 10 km - 80 kg

Relationship between the variables:

As the distance, or the weight increase, the rate will increase. This means that:

[tex]\frac{75}{x} = \frac{4*50}{10*80}[/tex]

[tex]\frac{75}{x} = \frac{200}{800}[/tex]

[tex]\frac{75}{x} = \frac{2}{8}[/tex]

[tex]x = \frac{75*8}{2} = 75*4 = 300[/tex]

The porter charges Rs 300 at this rate.

Answer:

x = 18

Step-by-step explanation:

When two parallel lines are intersected by a transversal, then same-side exterior angles are supplementary, meaning their angle measures add up 180 degrees. Applying this knowledge here, one can state that;

( 6x - 3 ) + 75 = 180

Simplify,

6x - 3 + 75 = 180

6x + 72 = 180

Inverse operations,

6x + 72 = 180

-72 -72

6x = 108

a. List the steps to form 13x +2.
b. List the steps to solve 13x + 2 = 41.

Answers

Answer:

Step-by-step explanation:

There isn't an exact answer for the first one since there are no like terms. But the steps to get 13x + 2= 41.

You'd have to find x.

In order to find x, you'll need to subtract 2 on both sides

13x + 2 = 41

- 2 = - 2

You'll end up with:

13x = 41

Next step is to divide 13 on both sides.

13x/ 13 = 41/ 13

So, x = 41/ 13

Or simplified to 3.153
