Find the value of x in the following diagrams (I drew them instead)

Answers

Answer:

1)  51°      2)     _?_     3) 55 ⁰          4) 30°

Step-by-step explanation:

3) First you find out what is G which = 90⁰, And then add the 90 and 75.

Then we will make this equation : (90+75) - 360 ( because Angle Sum property = Sum of all angles from the inside = 360⁰)

Then we do that which will be = 185-360

                                                   =  175

The we plus all the x's = x + 2x

                                        = 3x

then our equation is =    3x= 175

                                   x = 175/3  (Because of Transposition )

                                    x= 55°

And Then we do add and multiply

Like This: x=55

               2x= 2x55 = 110°

1) First add 67 and 62

Then our equation= (67+62)-180 ( Because of Interior angle sum property of triangles = sum of all interior angles = 180°)

Then = 129 - 180

         = 51 °

And then because of opposite angle are equal so our x= 51° because our angle in the triangle above x = 51° so it will be equal opposite (hope you understand)

4) First add 2x+4x

    Our Equation= (2x+4x)=90° (be cause right angle = 90°)

                          =     6x=90              

                            x =90/6

                              x = 15°

So, 2x= 2 x 15 = 30°

     4x = 4 x 15 = 60°

10 POINTS: Last week, Belle's Diner sold 8 milkshakes with whipped cream on top and 24 milkshakes without whipped cream. What percentage of the milkshakes had whipped cream?

10 points if solve, will give brainliest to the correct answer. please explain I really need help with solving percentages, ( Thanks SO MUCH!)
* THANKS!*

Answers

Answer:

25% of the milkshakes had whipped cream.

Step-by-step explanation:

Belle's Diner sold 8 milkshakes with whipped cream and 24 milkshakes without whipped cream. Given this information, we can add these two numbers to identify the total number of milkshakes Belle's Diner made:

[tex]8+24=32[/tex]

Belle's Diner made 32 milkshakes in total.

To find the percentage of milkshakes that had whipped cream, simply divide the number of milkshakes that had whipped cream (8) by the total number of milkshakes (32):

[tex]\frac{8}{32} =.25[/tex]

.25 as a percentage is 25% (move the decimal point two decimal places to the right).

Answer:

25% of the milkshakes have whipped cream on top.

Step-by-step explanation:

24+8=32

8/32=.25

*Note: To get the decimal form of any fraction you divide the numerator by the denominator.

.25 = 25%

Compare the decimals (and turn them into unlike decimals)

a) 3 or 0.8

b) 0.5 or 0.05

c) 1.5 or 1.50

d) 1.431 or 1.490

A doctor's office found that a lower outside temperature did not indicate a change in the number of appointments made. What can we determine from this information? 1.There is no correlation between outside temperature and number of appointments made. 2.There is a correlation between outside temperature and number of appointments made. However, there is no causation. This is because there is likely an increase in the number of appointments made with a decrease in the temperature outside. 3.There is a correlation between outside temperature and number of appointments made. There may or may not be causation. Further studies would have to be done to determine this.

Answers

Answer: 1, There is no correlation between outside temperature and number of appointments made.

Step-by-step explanation: It would be 1 because in the problem it states that even though temperatures were lower outside, their number of appointments had not changed. Because the number of appointments had not changed, there is no correlation between the temperature outside and number of appointments made.

Answer:

no correlation

Step-by-step explanation:

With the lack of information provided, I was able to create a base and general observation and create an equation based off everything I know and believe. (may not be accurate due to lack of information and background on assignment and curriculum)

TASHA: y = 7x + 15

(current distance) = (7 miles per hour) + (starting distance)

(29) = (14) + (15)

HENDRY: y = 6x + 25

(current distance = (6 miles per hour ) + (starting distance)

You have 6 pints of glaze. It takes ⅞ of a pint to glaze a bowl and 9/16 of a pint to glaze a plate

Answers

Your question is Incomplete

Is Your question this?

You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate.

A. How many bowls could you glaze

B. How many plates can you glaze

C. How much glaze will be left over?

If it is the Answer is below.

(If it not please tell me)

Answer/Step-by-step explanation:

Given:

6 Pints of glaze

takes 7/8 of pint to glaze a bowl

9/16 of a pint to glaze a plate

Part A) How many bowls could you glaze?

You have 6 pints of glaze. It takes 7/8  of a pint to glaze a bowl

so

To find the number of bowls divide 6 by 7/8

= 48/7 = 6.86 bowls

Therefore the answer to part A is equal to 6 bowls.

=================================================================

Part B) How many plates can you glaze?

You have 6 pints of glaze. It takes 9/16  of a pint to glaze a plate

so

To find the number of plates divide 6 by 9/16

=96/2 = 10.67 plates

Therefore the answer to part B is equal to 10 plates.

=================================================================

Part C) How much glaze will be left over?

[tex]Part A =6-6*\frac{7}{8} =6-\frac{42}{8} =\frac{48}{8} = \frac{42}{8}=\frac{3}{4}[/tex] pint of glazes left

[tex]Part B=6-10*\frac{9}{16} =6-\frac{45}{8} =\frac{48}{8} -\frac{45}{8} =\frac{3}{8}[/tex] pint of glazes left

Answers

Answer:

H = 3

7 7/8 ÷ 5 1/4 × 2

Step-by-step explanation:

Formula: Area = Base * height / 2

A = BH/2

We're looking for the the height so

Height = Area divided by base times 2

H = 7 7/8 ÷ 5 1/4 × 2

H = 1.5 ×2

H = 3

To confirm it:

7 7/8 =  3 * 5 1/4 ÷ 2

7 7/8 = 7 7/8

A fifteen passenger van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, the number of days the car be rented if they want to spend exactly $760.00 on the van rental?

A. 75.00 + 160.00x = 760.00
B. 75.00x – 160.00 = 760.00
C. 75.00 – 160.00x = 760.00
D. 75.00x + 160.00 = 760.00

Answers

Answer:

D. 75.00x+160.00=760.00

Answer:

Letter D.

Step-by-step explanation:

Since I believe we are trying to decipher the number of days the car must be rented if they want to spend exactly 760.00$, you must multiply the number of days by the rental price and add the fee. So, let’s test it out!

160.00 = 760.00

-160.00 -160.00 = 600.00

and then,

75.00x = 600.00

75.00 75.00 = 8
