Answer:

Step-by-step explanation:

Answer:

Crew: 32

Marty: 48

Blakely: 24

Step-by-step explanation:

I mainly just used guess and check. Crew is 32 years old. So, let's find Marty's age.

32 × 1. 5 = 48

Marty is 48. Now, let's find Blakely's age.

32 × 0.75 = 24

Add all the ages together.

32 + 48 + 24 = 104

Hope that helps.

Crew's age is 32, Marty's age is 48 and Blakey's age is 24

Let :

c represent Crew's age

m represent Marty's age

b represent Blakely's age

From the question, the following can be derived

m = 1.5c

b = 0.75c

m + b + c = 104

Substitute for m and b in the above equation

c + 1.5c + 0.75c = 104

3.25c = 104

divide both sides of the above equation by 3.25

c = 104 / 3.25

c = 32

Substitute for c in the equations that represent  Marty and Blakely's age

m = 1.5c

m = 1.5(32)

m = 48

b = 0.75c

0.75(32)

b = 24

Answer:

see below explanation

Step-by-step explanation:

1.  9 (x - 11) = 9

   9x - (9 * 11) = 9

   9x - 99 = 9

   x = 12

2.  4 (3x - 2) = 52

    (4 * 3x) - (4 * 2) = 52

    12x - 8 = 52

    x = 5

3.  44 = 2 (3x - 5)

    44 = (2 * 3x) - (2 * 5)

    44 = 6x - 10

    x = 9

4.  2x- 4/5 = 4

    2x - 2²/5 = 4

    5(2x) + (-2²)  /  5  = 4

    x = 12 / 5

5.   3x + 2/2 = 13

     3x + 1 = 13

    (3x + 1) + (-1) = 13 + (-1)

    x = 4

6.   4x -5/5 = 3

      4x - 1 = 3

      (4x - 1) + 1 = 3 + 1

      x = 1

7.   10x + 4/7 = 8

     10x + 2²/7  = 8

     7(10x) + 2²  /  7   = 8

     x = 26 / 35

8.    6x - 1/2 = 1

       2(6x) + (-1) / 2 = 1

      ((2 * 6x) - 1 ) / 2 = 1

      x = 1/4

Triangle angle sum theorem

Step-by-step explanation:

Answer:

-23

Step-by-step explanation:

Let first negative integer = x

The second = x +5

Their product = 126, hence,

x * (x +5) = 126

x^2 + 5x = 126

x^2 + 5x - 126 = 0

Two numbers whose product gives - 126 and sun gives 5

x(x + 14) - 9(x+14) =0

(x - 9) = 0 or (x + 14) = 0

x = 9 or x = - 14

Since x is said to be a negative integer,, the our x = - 14

First integer = - 14

Second integer = (x + 5) = (-14 + 5) = - 9

Sum of both integers :

-14 + - 9 = - 23

D. 4 hundredths

Step-by-step explanation:

Hello!

The second digit after the decimal point is 4 is shown by

0.04

The points after a decimal point go tenths, hundredths, thousandths etc.

The answer is D. 4 hundredths

Hope this helps!

Answer:

4 hundredths

Step-by-step explanation:

For values of decimals one should note that each additional digit after the decimal is a multiple of (1/10).

Using this knowledge, the first digit would be tenths, the second digit hundredths, the third digit thousandths, etc.

Hence a 4 in the second digit after the decimal would be equivalent to 4 * (1/100) = (4/100) or 4 hundredths.

Answer: the speed of the elevator is 4.6 miles per hour.

Step-by-step explanation:

Given, The elevator in the Washington Monument takes 75 seconds to travel 506 feet to the top floor.

Since 1 hour = 3600 seconds

⇒ 1 second = [tex]\dfrac{1}{3600}[/tex] hour

⇒ 75 seconds = [tex]\dfrac{75}{3600}[/tex] hour [tex]=\dfrac{1}{48}[/tex] hour

1 mile = 5280 feet

1 feet = [tex]\dfrac{1}{5280}[/tex] mile

506 feet = [tex]\dfrac{506}{5280}[/tex] miles [tex]=\dfrac{23}{240}[/tex] miles

Speed = [tex]\dfrac{Distance}{Time}[/tex]

[tex]=\dfrac{\dfrac{23}{240}}{\dfrac{1}{48}}\\\\=\dfrac{23\times48}{240}\\\\=\dfrac{23}{5}\\\\=4.6\text{ miles per hour}[/tex]

Hence, the speed of the elevator is 4.6 miles per hour.

Plane 'S'

Step-by-step explanation:

Since a plane is a two dimensional surface on which infinitely many points may lie.

In the picture attached, two planes (two dimensional) have been given.

Plane S

Plane T

Plane 'S' contains three points A, B and C and plane 'T' contains points D and E.

Therefore, the plane which contains points A, B and C is Plane 'S'.

The plane that contains points A, B and C is the plane S.

A plane is simply a 2-dimensional surface or figure.

The above definition of a plane means that, there are only two planes in the given figure.

These planes are:

Hence, the plane which contains points A, B and C is plane S.

Answer:

a= 18 girls in the class, b= 20 boys and 15 girls, 12 oranges better price.

Step-by-step explanation:

for question a, there are 18 girls in the class, this is how i worked it out:

the ratio of boys to girls is 4:3.

there are 24 boys.

24 is 6 times more than 4.

if boys are 6 times more than the original ratio, we also have to times the amount of girls by 6.

6x3= 18.

for question b i got 20 boys and 15 girls, this is how i did it.

there are 35 students in total.

4:3= boys to girls.

4+3=7

7 goes into 35 five times.

ratio of boys to girls is 4:3 so 5x4 for boys = 20 and 3x5 for girls = 15.

answer= 20 boys and 15 girls.

12 oranges is a better deal, this is how i worked it out.

it is 60 for 12 oranges.

it is 48 for 8 oranges.

12x5= 60 , 8x6=48.

you only have to times 12 by 5 to get it to the price but you have to times 8 by 6 to get it to the price, proving that 12 oranges for 60 is a better deal.
