find the area of these shapes:

Answer:

40°

Step-by-step explanation:

According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

Answer:

 40

Step-by-step explanation:

First you add 70 and 70 together to get 140 then minus it by 180.

Then you will get 40 degrees as your answer.

Answer:

1000-100=900,900+10=910,910-1=909

Step-by-step explanation:

Hey there!

1,000 - 100 + 10 - 1

1,000 - 100 = 900

= 900 + 10 - 1

900 + 10 = 910

= 910 - 1

= 909

Thus that’s why 1,000 - 100 + 10 - 1 is most likely equal to 909

Good luck on your assignment and enjoy your day!

Answer:

462

Step-by-step explanation:

720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.

720*5/6= 600

The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.

600*0.77 = 462

The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.

Given :

The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:

Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.

Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:

[tex]=\dfrac{720}{120}\times 100[/tex]

= 600

Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.

Step 4 - So, the total cost of the laptop at which an employee purchase is:

[tex]=\dfrac{77}{100}\times 600[/tex]

= 462

Answer:

1/5

Step-by-step explanation:

'of' is the same as multilpy

5/7 × ? = 1/7

? = 1/7 ÷ 5/7

? = 1/7 × 7/5 = 7/35

?=7/35

? = 1/5

check answer:

5/7 of 1/5 = 5/7 ×1/5 = 5/35 = 1/7

Answer:

C

Step-by-step explanation:

Remember that you flip the signs whenever you divide an inequality by a negative.

So here we divide both sides by negative four and then scan the signs to get

Answer:

y + 7 = (-14/17)(x - 8)

Step-by-step explanation:

We want the equation of this line in the point-slope form y - k = m(x - h).

We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above.  Then the other point is represented by (x, y) in the point slope form shown above:

Let (h, k) be 8, -7) and let (x, y) be (-9, 7).  Then,  y - k = m(x - h) becomes:

7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17

The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).  

Another way to get this result would be to find m in the usual way:

          rise           14

m = ------------- = --------- = -14/17 (same as before).

           run           -17

"Mathematically" you might have poor education whether it's bad teachers, bad school, or maybe you're just not working hard enough. Maybe you are educated and you're just comparing yourself against smarter people which might make you seem not very educated.

Answer:

$145.80

Step-by-step explanation:

The original cost of the product was $90.  There was a 162% markup.  In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%).  After taking away 100%, I am left with 62%.  I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8.  Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.

Answer:

[tex]\sqrt19[/tex]

Step-by-step explanation:

First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,

9^2 + b^2 = 10^2.

solve, 81 + b^2 = 100

then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].

Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.

4^2 + x^2 = 19.

Solve

16 + x^2 = 19

Subtract 16 from both sides

x^2 = 19

and finally, we take the square root of both sides

x = [tex]\sqrt19[/tex]

Step-by-step explanation:

ab                 =>    (5)(6) = 30

b + 3             =>    6 + 3 = 9

a + b + c       =>    5 + 6 + 7 = 18

3b + 4          =>    3(6) + 4 = 22

5a - c           =>    5(5) - 7 = 18

Answer:

The slope of the line is -1

Answer:

The x is the x-axis, which is a horizontal line. The y is the y-axis, which is a vertical line. The y-axis goes up or down, while the x-axis goes left or right.
