Which ordered pair is a solution of the equation?
7x-2y=-57x

Answer:

12.60

Step-by-step explanation:

Start off by the total which is 18. To find the percentage off you will have to make the 30% into a decimal, so simply move it two spaces to the left. Now you have .30. Multiply the decimal, .30, and the full amount, 18. Your equation now should be (.30)*(18). Your answer will be 5.40. 5.40 is what is off of the shirt from the original price, so subtract 5.40 from 18. Your equation now is (18-5.40) which is 12.60.

Answer:

½pi or 0.5pi units²

Step-by-step explanation:

Step-by-step explanation:

pi×diamiter = circumference

pi÷circumference = diamiter

3.14159265358979 (pi) ÷ 16

Calculate the diameter of a cylindrical pipe with a circumference of 16cm using the formula C = πd. Hence the diameter of the pipe is approximately 5.09 cm.

The circumference of a cylindrical pipe is related to its diameter through the formula C = πd, where C is the circumference, π is Pi (approximately 3.14159), and d is the diameter. Given that the circumference is 16 cm, we can use the formula to solve for the diameter:

16 = πd

16 = 3.14159d

d = 16 / 3.14159 ≈ 5.09 cm

Therefore, the diameter of the pipe is approximately 5.09 cm.

Final answer:

To find the volume of a rectangular prism, multiply its length, width, and height. For this specific prism, the volume is 2936.76 cubic inches.

Explanation:

Volume is calculated by multiplying the length, width, and height of a rectangular prism:

Volume = length x width x height

Given dimensions: length = 13.2 in, width = 13.8 in, height = 15.9 in.

Substitute the values into the formula: Volume = 13.2 in x 13.8 in x 15.9 in = 2936.76 in³

Therefore, the volume of the rectangular prism is 2936.76 cubic inches.

Answer:-228

Step-by-step explanation:

Answer:

98

Step-by-step explaination:

For this question, it is a direct variation. Hence, the equation would be formed accordingly, and the constant k would also be used.

z varies directly as x²

z= kx² where k is the constant

z = 8

x = 2

Putting the figures in the equation, we have

8=2²(k)

8= 4k

Dividing both sides by 4, we have

k = 8/4

k = 2

Solving for z now, we substitute k with 2. And x with 7

z=kx²

z = 2(7²)

z= 2(49)

z= 98

If it were indirect variation, the constant would have been 1/k. We also have other types of variation, Indirect variation, partial variation and joint variation.

When you graph it on a graph piece of paper it is a right triangle

Answer:

2.1 , 7.2 , 7.5 does NOT make a right triangle

Step-by-step explanation:

acute     [tex]c^{2} < a^{2} + b^{2}[/tex]

obtuse    [tex]c^{2} > a^{2} + b^{2} \\[/tex]

right angled   [tex]c^{2} = a^{2} + b^{2}[/tex]

c is the hypotenuse

a and b are the adjacent and the opposite

the values given are 2.1  , 7.2  , 7.5

hence :

c would be 2.1

a would be 7.2

b would be 7.5

now we can put this into the right angled triangle formula to see if its correct.

[tex]c^{2} = a^{2} + b^{2}[/tex]

lets first see the value of [tex]a^{2} + b^{2}[/tex]

= 7.2^2  +  7.5^2

[tex]a^{2} + b^{2}[/tex] = 108.09

to check if its a right angled triangle we check if the value of c^2 gives 108.09.

find the value of [tex]c^{2}[/tex]

= 2.1 ^2

[tex]c^{2}[/tex] =4.41

hence 4.41 is NOT equal to 108.09

hence its not a right angled triangle but rather an acute angle.

Step-by-step explanation:

Cost of paint brushes= Total cost - cost of paint

                                   = 71 - 50 = $21

No.ofpaint brushes =21/3.50 = 21*10/3.5*10

                                 = 210/35 = 6

Answer:

Natasha paid $6 per paintbrush

Step-by-step explanation:

we can make use of variables

p = paint

b = brushes

bought paintbrushes and paint for a total of $71. . The brushes cost $3.50 per brush and the paint cost $50

we can create an equation from the information

3.5b + 50p = 71

since 1 paint is bought

3.5 b + 50 (1) = 71

3.5b = 71 - 50

3.5b = 21

b = 21/3.5

b = 6

Answer:

The axis of symmetry is -9

Step-by-step explanation: The AOS will always be the x value of your vertex.

Answer:

Step-by-step explanation:

a(n) = a + (n-1)d

a(33) = 3 + (33-1)*(-1)

        =  3 + 32*(-1)

         = 3 - 32

         = -29

The 33rd term (a33) in an arithmetic sequence starting with 3 and a common difference of -1 is -29. This is achieved by using the formula for finding a term in an arithmetic sequence.

The question is asking for the 33rd term in a sequence where the first term is 3 and each following term is derived by subtracting 1 from the previous term, a common process known as an arithmetic sequence. The formula to find any term (an) in an arithmetic sequence is an = a1 + (n - 1)d, where a1 is the first term, d is the common difference, and n is the term number.

So, to find a(33) (the 33rd term), we will fill in the formula as follows: a33 = 3 + (33 - 1)*-1

Which simplifies to: a33 = 3 - 32 = -29

So the 33rd term of the sequence is -29.

Answer:

The 2 angles are 12.2 and 77.8 degrees.

Step-by-step explanation:

Let  the measure of one angle be x degrees, then it's complementary angle = 90-x degrees.

So we have the equation:

x =  90 - x - 65.6

2x =  90 - 65.6 = 24.4

x = 12.2 degrees.

Its complement = 90 - 12.2 = 77.8 degrees.
