HELP ME AGAIN CUZ AM DUMB (7th grade math)
A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the pan?
(32 dollars) (100 percent minus 15 percent) = (32 dollars) (85 percent) = 27 dollars and 20 cents
(32 dollars) (15 percent) = 4 dollars and 80 cents
(32 dollars) (15 percent) + 32 dollars = 4 dollars and 80 cents + 32 dollars = 36 dollars and 80 cents
(32 dollars) (185 percent) = 59 dollars and 20 cents

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:

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

Question:

Find 4 possible solutions in the context of the problem.

The 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)

Given the equation that models the situation expressed as:

4x + 6y = 48

We are to find 4 possible solutions for x and y. Note that the values of x and y must be integers.

If there are no cars i.e. at when x = 0

4(0) + 6y = 48

0 + 6y = 48

6y = 48

y = 48/6

y = 8

One of the solution is (0, 8)

If there are 3 cars, i.e. at when x = 0

4(3) + 6y = 48

12 + 6y = 48

6y = 48 - 12

y = 36/6

y = 6

The second solution will be (3, 6)

If there are 6 cars, i.e. at when x = 6

4(6) + 6y = 48

24 + 6y = 48

6y = 48 - 24

y = 24/6

y = 4

The third solution will be (6, 3)

If there are 9 cars, i.e. at when x = 9

4(9) + 6y = 48

36 + 6y = 48

6y = 48 - 36

y = 12/6

y = 2

The fourth solution will be (9, 2)

Hence the 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)

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.

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

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

+

-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:

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:

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
