Answer:

Step-by-step explanation:

9x - 5 = 58

9x = 63

x = 7

<2 = 32°

7y + 27 + 58 + 32 = 180

7y + 117 = 180

7y = 63

y = 9

for <1: x + 58 = 180

       x = 122°

Answer:

The area covered by the wiper blade is 35 square inches

Step-by-step explanation:

Here, we want to calculate the area covered by the blade of the wiper

Mathematically, this is simply the area of the sector formed by the wiper on the screen

This can be calculated as follows;

theta/360 * pi * r^2

From the question theta = 50 degrees

r = the length of the wiper = 9 inches

So the area is;

50/360 * 22/7 * 9^2 = 35.35714285714286

This is closest to 35 square inches

Given

[tex]x = -7.5[/tex]

[tex]Expression: -3.8x + 6[/tex]

Required

Determine Gaira mistake

When Gaira solved the expression, she solved as:

[tex]-3.8x + 6x[/tex]

Giving her

[tex]-3.8x * -7.5 + 6 * -7.5[/tex]

This is incorrect as the correct expression is

[tex]-3.8x + 6[/tex]

and it is solved as follows:

Substitute -7.5 for x in -3.8x + 6

[tex]-3.8x + 6[/tex]

[tex]-3.8 * -7.5 + 6[/tex]

[tex]28.5 + 6[/tex]

[tex]34.5[/tex]

34.5 is the correct solution

Answer:

Gaira made a mistake when substituting the value –7.5 in for x. She multiplied both terms of the expression by –7.5 when she should have only multiplied –3.8 by –7.5. The correct answer is 34.5.

Did the ED2020

Answer:

17 feet

Step-by-step explanation:

Here, we want to calculate the vertical distance between Carl’s and Cameron’s feet

Since Carl is at the base of the pool, the distance between the water surface and the base of the pool will be 15 feet

We are also told they Cameron is on a diving platform 2 feet above;

So the distance between the two of them will be ;

15 feet + 2 feet = 17 feet

Answer:

(4.91, 3.5)

Step-by-step explanation:

6x+21y=103

+

-6x+23y=51

=

44y=154

y=3.5

6x+21(3.5)=103

6x+73.5=103

6x=29.5

x=4.91

(4.91, 3.5)

Answer:

The answer is (4,6) because you would have to eliminate the -6 and 6 to get the y which would be 24y and then divide 154/24 which is roughly 6 and then put that in to get x which is roughly 4

you can also use elimiation for y as well

Answer:

All the student are members of the planetarium's frequent visitor program.

Step-by-step explanation:

Let x represent the number of student who are members of the planetarium's frequent visitor program.

And let y represent the who are not a member.

Then two equations can be formed using the provided data:

x + y = 19...(i)

11x + 13y = 209...(ii)

Multiply (i) by 13 and solve for x as follows:

13x + 13y = 247

-11x  - 13y = -209

2x = 38

x = 19

Substitute x = 19 in (i) and solve for y as follows:

x + y = 19

19 + y = 19

y = 0

Thus, all the student are members of the planetarium's frequent visitor program.

Answer:

x=31/14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−4x+1=−9x−16+9x+16

−4x+1=−9x+−16+9x+16

−4x+1=(−9x+9x)+(−16+16)(Combine Like Terms)

−4x+1=0

−4x+1=0

Step 2: Subtract 1 from both sides.

−4x+1−1=0−1

−4x=−1

Step 3: Divide both sides by -4.

−4x−4=−1/-4

x=1/4

The answer is [tex]-\frac{1}{15}[/tex]

Step-by-step explanation:

I used my calculator and inputted everything.

Answer:

(– 4,– 5) = –9

(– 2,– 6) = –8

Answer:

[tex]x = \frac{-15}{2}[/tex]

Step-by-step explanation:

to answer these types of questions, we want to isolate the variable to one side of the equation

[tex]4x + 9 = 2x - 6\\4x - 2x = -6 - 9\\2x = -15\\x = \frac{-15}{2}[/tex]

Answer:

x = -7.5 :)

Step-by-step explanation:

4x + 9 = 2x - 6

-2x         -2x

----------------------

  2x + 9 =  -6

        -9      -9

-----------------------

     2x = -15

     ---     ----

     2       2

x = -7.5  

Answer:

The approximate volume of dirt in the hill = 70372 ft³

Step-by-step explanation:

From the given information:

Laura uses a model of a truncated cone to estimate the volume of the dirt.

This implies that the volume of the dirt in the large hill took the shape of a truncated cone.

Her estimate then includes:

a base diameter = 80 feet ; then the base raidus (R) = 80 feet/2 = 40 feet

a top diameter  = 40 feet ; then the top radius (r) =  40 feet/2 = 20 feet

a helght = 24 feet.

Using the formula for the volume of a truncated cone :

[tex]V =\dfrac{1}{3} \times \pi \times h \times ( r^2 +r \times R+ R^2)[/tex]

[tex]V =\dfrac{1}{3} \times \pi \times 24 \times ( 20^2 +20 \times 40+ 40^2)[/tex]

[tex]V =25.133 \times ( 400 +20 \times 40+ 1600)[/tex]

V = 70371.675 ft³

V ≅ 70372 ft³
