Answer:

  153 square units

Step-by-step explanation:

The figure is drawn in the attachment with some lengths and points labeled.

The figure can be considered to have an area that is the sum of the areas of rectangle ABFE and triangle FGH, with the area of triangle BCD subtracted.

That area is ...

  A = area(ABFE) +area(FGH) -area(BCD)

  = (15)(9) +(1/2)(9)(6) -(1/2)(6)(3)

  = 135 +27 -9 = 153 . . . square units

Answer:

16 boxes will be needed for 122 books.

Step-by-step explanation:

Given that,

Each box can hold 8 books.

We need to find the number of boxes needed for 122 books. It can be calculated as follows :

[tex]\dfrac{122}{8}[/tex] = 15.25

It means 15 boxes can be filled and 16 boxes will be needed for 122 books.

Answer: He can buy 5 ties

Step-by-step explanation:

12+10=22. 4x5=20. 22+20=42. If you add 1 more tie, you  will have $46, so you cannot add one more tie. So the most amount of ties he can buy is 5 ties, with $3 left to spare.

Answer:

60 miles

Step-by-step explanation:

Let us assume the distance between his home and place of appointment be x and t would be time taken at 40 mph

As we know that

Distance = speed × time

So,

x = 40t ............(1)

As he left the house 15 minutes late and also drove his car at 50 mph and arrive 3 minutes early

So,

15 minutes = 15 ÷ 60 = 0.25 hour

3 minutes = 3 ÷ 60 = 0.05 hour

Now the actual time taken is

= t - 0.25 - 0.05

=  t - 0.30

x = 50(t - 0.30)

x = 50t - 15.............(2)

Now

40t = 50t - 15

10t = 26

t = 3 ÷ 2 hour

Now

x = 40 × 3 ÷ 2

= 60 miles

Answer:

2x+3+x2 if x=4 is 27

Step-by-step explanation:

2*x or 2*4=8

8+3=11;

and x or 4 times itself is 16

so we add it all together and get 27.

Have a great day!

Answer:

27

Step-by-step explanation:

Not sure if you mean x to the power of 2, so I'll assume that.

Replacing the variable for 4 should look like:

2(4) + 3 + 4^2

8 + 3 + 16 (4 to the power of 2 is equivalent to 4 x 4 which is 16)

Now add them all, 27.

Answer:

$75.65

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 890 × 0.0425 × 2 = 75.65

I = $ 75.65

The simple interest accumulated

on a principal of $ 890.00

at a rate of 4.25% per year

for 2 years is $ 75.65.

Answer:

The teams can be placed in 479,001,600 ways.

Step-by-step explanation:

To solve this question, we want to know in how many ways 12 elements can be arranged.

Number of possible arrangements of x elements:

The number of possible arrangments of x elements is given by:

[tex]A_{x} = x![/tex]

In this question:

12 teams, so arrangment of 12 elements.

[tex]A_{12} = 12! = 479001600[/tex]

The teams can be placed in 479,001,600 ways.

Answer:

x = 15/27

Step-by-step explanation:

3(2x + 7x - 5)

Distribute the 3

6x + 21x - 15

Combine like terms

27x - 15 = 0

27x = 15

x = 15/27

Answer:

27x - 15 is your expression

Step-by-step explanation:

3 x 2x = 6x and 3 x 7x = 21x so 21x + 6x = 27x and 3 x 5 = 15 so 27x - 15 is your expression

Answer:

9 lemonade, 3 tea, 4 water

Answer: Robert should serve 3 for tea, 9 for lemonade, and 4 for water.

Step-by-step explanation:

Since you don't know how many friends are drinking lemonade or tea, you should give them variables.

x = amount of friends drinking tea

3x = amount of friends drinking lemonade

We already know how many are drinking water, so there's no need for a variable.

Then, make an equation:

x + 3x + 4 = 16

Simplify:

4x + 4 = 16

Isolate the variable by subtracting 4 from both sides:

4x = 12

Isolate the variable by dividing both sides by 4:

x = 3, so 3 friends are drinking tea

3x = 9, so 9 friends are drinking lemonade

Double check the work by replacing the variables with their actual numbers:

3 + 9 + 4 = 16

Simplify:

16 = 16

Therefore, the answer is correct.
