Answer:

8/21

Step-by-step explanation:

Area of a rectangle is L*W so for only the shaded bits of the rectangle the length (1/7*4) would be 4/7 and the width would be (1/3*2) so 2/3. then you would multiply them togehter by finding multiplying the bottoms togther  and the tops together (4*2)/(7*3) this gives 8/21. Hope this helps!!

Answer:

There are 7456 seats on the lower level and there are 5044 seats on the middle level.

Step-by-step explanation:

Let 'X" be the number of seats on the upper level. Then we can find how many seats are on the lower level by solving the following equation...

# of seats on the lower level = 3x - 50

# of seats on the lower level = 3(2502) - 50

# of seats on the lower level = 7456

Now we just make the equation for the number of seats on the middle level, and so we get...

# of seats on the middle level = 2x + 40

# of seats on the middle level = 2(2502) + 40

# of seats on the middle level = 5044

Answer:

$1146.216

Step-by-step explanation:

Given data

Principal= $879

Rate= 19%

Time = 18months= 1.6 years

The expression for the simple interest is

A=P(1+rt)

substitute

A=879(1+0.19*1.6)

A= 897(1+0.304)

A= 879*(1.304)

A= $1146.216

Hence the amount to be paid is $1146.216

Answer:

8 Nickels

Step-by-step explanation:

Since a Nickel is worth 5 cents ($0.05)

And a Quarter is worth 25 ($0.25)

and theres 22 coins

8 of those coins would be nickels which would mean we add 8 nickels up

8 x 0.05 = 0.4

then we add the quarters up

14 x 0.25 = 3.5

3.5 + 0.4 = $3.90

Answer:

Step-by-step explanation:

How many months begin with J or A ? 5

How many months total? 12

The probability that the sale will be in a month begins with the letter J or A. is 5/12

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

A store owner plans to have his annual "Going Out of Business Sale." If each month has an equal chance of being selected,

The total number of months begins with J or A =  5

The total months =12

The probability that the sale will be in a month begins with the letter J or A.​

= 5/12

Answer:

d. 42

Step-by-step explanation:

PEDMAS

We do brackets first, so:

4 + 4 = 8

Then multiplication,

5 x 8 = 40

Then addition

40 + 2 = 42

4+4=8

5(8)+2

5x8=40

40+2= 42

Answer:

40 gal

Step-by-step explanation:

The capacity of the machine is 140 gallons, and it must be filled.

In a 50% glycol solution, the amount of glycol in 140 gallons of solution is

50% * 140 gallons = 70 gallons.

Once the machine is full with 140 gallons of 50% glycol solution, it will have 70 gallons of glycol.

The machine now has 50 gallons of 60% glycol solution.

60% * 50 gallons = 30 gallons

The machine has now 30 gallons of glycol.

70 gal - 30 gal = 40 gal

You must add another 40 gallons of glycol.

Answer : M{A}=72

This is a triangle, meaning the total degree will be 180.

Answer:

3. 37

4. 59

5. 79

Step-by-step explanation:

All the angles of the triangle add up to 180°

3. 180-(31+112) = 37°

4. (4x-18)+(8x+7)+(5x+4) = 180

   17x-7 = 180

17x = 187

x =11

we have found the x now we need to input it to find m∠z

5x+4

=5×11+4

=59°

5. A straight angle is 180° so if the outside angle is 129 the inside one will be 51°

(2x-3)+(x+9)+51 = 180

3x+57 = 180

3x = 123

x = 41

Now we need to find m∠L

2x-3

= 2×41-3

= 79°
