Cost of 1 pen = 15.75

Cost of 7 pens = 15.75 × 7 = 110.25

Answer:

$110.25

Step-by-step explanation:

1 pen = $15.75

7 pens x $15.75 = $110.25

Step-by-step explanation:

Answer:

31.5

Step-by-step explanation:

First we want to find what side NP is equal to. To do that we divide 4 by 12

12/4=3 so side mp=3

next we want to find the scale factor of the rectangles. to do that we divide 4 from 9

9/4=2.25

next we want to find what side st is equal too

to do that we multiply 3 by 2.25

3x2.25=6.75

finally we want to find the perimeter and to do that we do 2(6.75)+2(9)

2(6.75)+2(9)=31.5 so the perimeter of rectangle RSTU is 31.5

hope this helps :)

Answer:

correct

Step-by-step explanation:

Answer:

a)  n  ≥ -2

b)  v > -6

Step-by-step explanation:

You did not state what you would like us to do with these. I will assume simplify.

a)

− 5 ( 6 n + 6 ) ≤ 30 first, distribute -5

-30 n + -30  ≤ 30 now, add 30 to both sides so we may isolate n our variable

-30 n  ≤ 60 now, divide -30 on both sides so we may isolate n completely. When we do this, the sign changes direction

n  ≥ -2

b)

8 v − 4 ( v − 8 ) > 8 first, distribute -4 (note: two negatives equal a positive)

8 v - 4v + 32  > 8 now, simplify

4v + 32  > 8 now, subtract 32 from both sides

4v > -24 now, divide both sides by 4 to isolate v

4v > -24

v > -6

Answer:

It would cost $46.50 to buy 12 gallons of gas.

Step-by-step explanation:

1. Replace the variables in [tex]P = 3.75g + 1.5[/tex] with the values you know:

[tex]P = 3.75g + 1.5, \text{ where } g =12\\P=3.75(12)+1.5[/tex]

2. Solve for P:

[tex]P=3.75(12)+1.5\\P=45+1.5\\P=46.5[/tex]

Answer:

B

Step-by-step explanation:

Answer:

The answer is 98

Step-by-step explanation:

Subtract the sum of the two angles from 180 degrees.

The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

62+20=82

180-82=98

98+20+62=180

Answer:

1/2×4×2×6+8×5×3=144cm²

Answer:

42

Step-by-step explanation:

You can use proportions to solve this problem.

[tex]\frac{5cm}{30km}[/tex]=[tex]\frac{7cm}{xkm}[/tex]

Now just cross multiply.

5cm*Xkm=7cm*30km

you can simplify the cm and km since its multipying.

5x=210

x=42

1. The factoring step is

sin²θ - cos²θ sin²θ = sin²θ (1 - cos²θ)

Then the Pythagorean identity is invoked:

cos²θ + sin²θ = 1   →   1 - cos²θ = sin²θ

so that

sin²θ - cos²θ sin²θ = sin²θ sin²θ = sin⁴θ

(third option)

2. Recall that a ² - b ² = (a - b) (a + b). The numerator here is such a difference of squares:

csc²x - 1 = (cscx - 1) (cscx + 1)

Then

(csc²x - 1) / (1 + sinx) = ((cscx - 1) (cscx + 1)) / (1 + sinx)

Recall that cscx = 1/sinx, so rewrite this as

… = ((1/sinx - 1) (1/sinx + 1)) / (1 + sinx)

In the numerator, pull out a factor of 1/sinx from both terms:

… = (1/sinx (1 - sinx) × 1/sinx (1 + sinx)) / (1 + sinx)

… = ((1 - sinx) (1 + sinx)) / (sin²x (1 + sinx))

Cancel the common factor of 1 + sinx :

… = (1 - sinx) / sin²x

Expand the fraction and rewrite sin in terms of csc :

… = 1/sin²x - sinx/sin²x

… = 1/sin²x - 1/sinx

… = csc²x - cscx

Factor out cscx to get the second option,

… = cscx (cscx - 1)

Answer

sequence -28,-34,-40

1st term = -28

comman difference = -34 - (-28) = -6

comman term = a + (n-1)d

a= first term

d= difference

comman term = a + (n-1)d

                       = -28 + (n-1)(-6)

                       = -28 -6n +6

                       = -22-6n

1st term --> n =1 = -22 -6.1 =  -22 -6 =-28

2nd term --> n =2 = -22 -6.2 =  -22 -12 =-34

81st term --> n =81 = -22 -6.81 =  -22 -486 = -508

There are two different categories of transformations: The rigid transformation, which does not change the shape or size of the preimage. The non-rigid transformation, which will change the size but not the shape of the preimage.

Answer:

19.15 miles/gallon

Step-by-step explanation:

Gasoline used = 8.6 gallons

Distance driven = 164.7 miles

Number of miles per gallon = Distance driven / Gasoline used

= 164.7 miles / 8.6 gallons

= 19.151162790697 miles/gallon

Approximately 19.15 miles/gallon

Number of miles per gallon of gasoline her vehicle gets is 19.15 miles/gallon

B

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the volume of prism be Vp

Let the Volume of pyramid be Vy

Vp = Base Area * Height .... 1

Vy = Base * Height/3 ....2

From 2;

Vp = BH/3

BH = 3Vy

Since Vp = BH, then;

Vp = 3Vy

This shows that the volume of prism is three times as large as pyramids volume
