Answer:

a) 1790 b) 1.79

Step-by-step explanation:

a) you just add to get the perimiter 2(900) + 2(400) to get 1790

b) 1000 meters makes a kilometer so we divide by 1000 and get 1.79 for the kilometers

Answer:

27 = - 4x + 11

solve using inverse operations

27 = -4x + 11

-11           -11

16 = -4x

/-4    /-4

-4 = x

Answer:

-4

Step-by-step explanation:

Notice that the only way to multiply 2 numbers from each of the polynomials and get an x term is to multiply a constant and an x term.

The only ways to do that is to multiply -6x by 3 and 7x by 2.

After you're done multiplying, just combine the 2 like terms:

-18x+14x

=-4x

Therefore, the coefficient of the x term is -4.

Answer:

C

Step-by-step explanation:

Given

5x + 7 ≤ - 3 or 3x - 4 ≥ 11

Solve the inequalities either side of the or

5x + 7 ≤ - 3 ( subtract 7 from both sides )

5x ≤ - 10 ( divide both sides by 5 )

x ≤ - 2

or

3x - 4 ≥ 11 ( add 4 to both sides )

3x ≥ 15 ( divide both sides by 3 )

x ≥ 5

Solution is x ≤ - 2 or x ≥ 5 → C

Answer:

The soil will occupy in 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.

Step-by-step explanation:

The volume of a square based pyramid = V = a²h/3

a = base edge or side length = 36cm

h = height = 36cm

V = 36² × 36/3

V = 15552cm³

Luis wants to fill the pot with soil so that the soil takes up 75 % the pot's volume.

75% of the pot's volume =

75/100 × 15552cm³

= 11664cm³

The soil will occupy 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.

Answer:

The soil will reach about 32.7 cm up the pot.

Answer:

x = 32 degrees

Step-by-step explanation:

since there is a line intersecting both of the lines you would do the opposite number to solve the problem. basically what i am trying to say is.

A straight line equals 180 degrees

and the given angle is 148 degrees

so just subtract.

180 degrees - 148 degrees = 32 degrees

so x = 32 degrees

to see if it is reasonable, look at the angle

if you look you can see that it is an acute angle

so, since 32 degrees is an acute angle, the answer is also reasonable.

so like i said,

x = 32 degrees

The interior angles of parallel lines and a transversal are the angles between the parallel lines.

The value of x is 32 degrees

Alternate interior angles of a parallel line add up to 180 degrees.

So:

[tex]\mathbf{148 + x = 180}[/tex]

Subtract 148 from both sides

[tex]\mathbf{148 - 148+ x = 180 - 148}[/tex]

Evaluate like terms

[tex]\mathbf{x = 32}[/tex]

Hence, the value of x is 32 degrees

A forth can be represented as 25% or 0.25 as a decimal. (100/4 = 25)

To determine how many kids got an A, we figure out was 25% of 24 is.

0.25 x 24 = 6

Therefore, 6 kids in the class got an A.

Answer:

The number of touch downs = 11

The number of extra points = 4

Step-by-step explanation:

The number of times UT Longhorns scored = 15 times

The composition of the scores = Touch down and point kicks

The points with which UT Longhorns won the game = 70-3

The points that came from each touch down = 6 points

The points that came from each point kick = 1 points

We have;

The number of touch downs + Point kicks = 15

The number of touch downs = 15 - Point kicks

Let the number of point kicks = P

Therefore;

The number of touch downs = 15 - Point kicks = 15 - P

The number of touch downs = 15 - P

Given that the total points of UT Longhorns = 70, we have;

6 × (15 - P) + 1 × P = 70

90 - 6·P + P = 70

5·P = 90 - 70 = 20

P = 4

∴ The number of point kicks = P = 4

The number of point kicks, extra points = 4

The number of touch downs = 15 - P = 15 - 4 = 11

The number of touch downs = 11

Answer:

C) 18

Step-by-step explanation:

All you have to do is solve the equation.

2.25x + 5 = 45.50 (subtract 5 on each side)

2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)

x = 18

40.50/2.25 = 18

Answer:

18 Miles

Step-by-step explanation:

If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.

Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

for this question your answer is D

25 X 8 = 200

500 - 200 = 300

So if you have 8 weeks and spend 25 dollars a week then you would have $300 left over at the end of the 8 weeks.
