Solve for d in the proportion.

10/15 equals d/12

Solve For D In The Proportion.10/15 Equals D/12

Answers

Answer 1

Answer:

8

Step-by-step explanation:

Since there are two fractions, it is easiest to cross multiply the fractions before doing anything else. Basically:

10/15 = d/12  becomes 120 = 15d.

then you just divide 15 to both sides to get your answer:

d = 120/15, which is the equivalent of d = 8.

For his art project, Dorian is using square tiles of different sizes and colors to make a mosaic. The first three tiles are: 1. A = 5 cm2 2. A = 7 cm2 3. A = 9 cm2


which tile's side lengths will Dorian need to estimate?

Answers

Answer:

3cm²

Step-by-step explanation:

Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square

Area of a square = L²

L is the side length of the tiles

For the tiles with area 7cm²

7 =  L²

L² = 7

L = √7

L = 2.65cm

For tiles with area 5cm²

5 =  L²

L² = 5

L = √5

L = 2.24cm

For tiles with area 9cm²

9 =  L²

L² = 9

L = √9

L = 3.0cm

Since for all the square tiles the length of the tile is ≤ 3 cm, then the  tile's side lengths that Dorian will need to estimate is approximately 3cm

What is Linear Equation in 2 variables?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Given data ,

g ( x ) = x² - 5 x + 8

To solve for g ( 5 a - 2 ) + 3 g ( 2 a ) , substitute for the value of x

Therefore ,

g ( 5 a - 2 ) = ( 5 a - 2 )² - 5 ( 5 a - 2 ) + 8

                  = ( 25 a² + 4 - 20 a ) - 25 a + 10 + 8

                  = 25 a² - 45 a + 22

3 g ( 2 a ) = 3 [ (2 a )² - 10 a + 8 ]

                = 3 [ 4 a² - 10 a + 8 ]

                = 12 a² - 10 a + 8

And , g ( 5 a - 2 ) + 3 g ( 2 a ) = 25 a² - 45 a + 22 + ( 12 a² - 10 a + 8 )

                                               = 37 a² - 55 a + 30

Hence , the value of the equation will be 37 a² - 55 a + 30

Write and equation passing through the point (-3, 1) that is parallel to y=2x+5

Answers

Answer:

y = 2x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 5 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (- 3, 1) into the partial equation

1 = - 6 + c ⇒ c = 1 + 6 = 7

y = 2x + 7 ← equation of parallel line

What’s the 69th term of the arithmetic sequence -13, -33, -53

Answers

Answer:

(-1373)

Step-by-step explanation:

a = 1st term = -13

Common difference = d = 2nd term - 1st term

                            d = -33 - (-13) = -33 + 13

                             d = -20

n = 69

nth term = a + (n-1)d

69th term = (-13) + 68 * (-20)

                 = -13 - 1360

Which of the following equations is equivalent to 3(a + 4) – 5(a – 2) = 22?
8a + 22 = 22
8a + 2 = 22
-2a + 2 = 22
-2a + 22 = 22

Answers

-2a + 22 = 22 is the answer

Answer:

-2a + 22 = 22

Step-by-step explanation:

Distribute the 3 to both terms in (a + 4) and -5 to both terms in (a – 2) to get 3a + 12 – 5a + 10 = 22. Simplify to get -2a + 22 = 22.

Julio is paid 1.4 times his normal hourly rate for each hour he works over 32 hours in a week. Last week he worked 43 hours and earned $535.62. Enter and solve an equation to find Julio's normal hourly rate, r. Complete the explanation how you know that your answer is reasonable.

Answers

Answer:

[tex]r = \$14.71[/tex]

Step-by-step explanation:

Given

Normal Hour = 32 hours

Overtime = Hours above 32

Rate for Overtime = 1.4 times normal rate

Earnings = $535.62

Required

Determine the normal hour pay

First, we need to determine the hours worked overtime.

This is:

[tex]Overtime = 43 - 32[/tex]

[tex]Overtime = 11[/tex]

The equation that binds all the parameters is:

[tex]Earnings = Normal\ Hour * Normal\ Rate + Overtime * Overtime\ Rate[/tex]

This gives:

[tex]535.62 = 21 * r + 11 * 1.4r[/tex]

[tex]535.62 = 21r + 15.4r[/tex]

[tex]535.62 = 36.4r[/tex]

Solve for r

[tex]r = 535.62/36.4[/tex]

[tex]r = \$14.71[/tex]

Sam is flying from Columbus, Ohio to Kralendijk, Bonaire, a distance of 2,488 miles. First, he flies 995 miles to Miami, Florida.

Answers

Answer:

460 miles

Step-by-step explanation:

Given

Total = 2488 miles

Miami = 995 miles

San Juan = 1033 miles

Required

Determine the remaining distance

Assuming the points are on a straight path.

The remaining distance is:

Remainder = Total - Miami - San Juan

Remainder = 2488 - 995 - 1033

Remainder = 460 miles
