Answer:

Part A: x = -39/4 or -9.75

Part B: y = 1/2 or .5

Step-by-step explanation:

Part C: Multiply the bottom equation by 2, obtaining 4x + 10y = -34. Subtract the top equation (4x + 4y = -37) from this equation, obtaining 6y = 3. Solving this, y = 1/2

(y = .5). Substitute this value of y into the equation 4x + 4y = -37, and then solve for x:

4x + 4(1/2) = -37

4x + 2 = -37

4x = -39, so x = -39/4 or -9.75

To find the area of the circle:

   ⇒ must know the area's formula ⇒ [tex]\pi r^2[/tex]

Let's consider the information given

         ⇒ the radius' length is half of the diameter

             ⇒ thus the radius' length is 3.5 in

Let's calculate the area:

    [tex]Area=\pi r^2=\pi (3.5^2)=12.25\pi in^2[/tex]

The problem asks us to leave the answer in terms of '[tex]\pi[/tex]' which means that we won't multiply '[tex]\pi[/tex]' to the final answer, but leave it there,

The mileage that the supervisor will achieve that is within a z-score of 1.5 is; 23.6

Formula for z-score in statistics is;

z = (x' - μ)/s

Where;

x' is sample mean

μ is population mean

s is sample standard deviation

We are given;

x' = 29

Standard deviation; s = 3.6

z = 1.5

Thus;

1.5 = (29 - μ)/3.6

μ = 29 - (1.5 × 3.6)

μ = 23.6

Answer:

-5 is the answer to the question

The quantity of NOx the vehicle will release in 15 years for running 22000miles each year will be 458700 grams.

Multiplication is an operation that represents the basic idea of repeated addition of the same number.

here in the question we will multiply the Nox released by the vehicle per year to 15 years.

Given that: Vehicle releases 1.39 Nox per mile

Now if vehicle is running 22000 miles per year so the Nox released per year will be =22000x1.39=30580 grams per year

For 15 years the NOx released by the vehicle will be = 30580x15=458700 grams

Hence the quantity of NOx the vehicle will release in 15 years for running 22000miles each year will be 458700 grams.

Answer:

110 decreased by 30% is 77.

Step-by-step explanation:

To do this, what we do is simply take 30% of 110 and subtract it from 110.

30% of 110. A trick to easily figure this out is multipling 110 by 30 and dividing by 100.

110*30 = 3300

3300 / 100 = 33

110 - 33 = 77

110 decreased by 30% is 77.

You have to add 1.5 to each input number to find its corresponding output number.

Flori's Flower Shop have 48 white flowers, 40 red flowers, 30 yellow flowers and 15 purple flowers, whose sum equals 133 flowers, which is fewer than 150 flowers.

Flori's Flower shop owns a quantity less than 150 flowers, in which there are four kinds of flowers according to color: (purple - p, yellow - y, red - r, white - w), each variable represents positive integers. Now we proceed to construct the system of equation that describes the situation:

z < 150     (1)

p + y + r + w = z    (2)

p = y/2     (3)

y = 3 · r/4     (4)

r = 5 · w/6     (5)

By (1) and (3) in (2):

y/2 + y + r + w < 150

By (4):

3 · y/2 + r + w < 150

9 · r/8 + r + w < 150

17 · r/8 + w < 150

By (5):

85 · w/48 + w < 150

133 · w/48 < 150

133 · w < 7200

w < 54.135

Now we assume that w = 48, then we have the following solution for the flower shop: r = 40, y = 30, p = 15.

Flori's Flower Shop have 48 white flowers, 40 red flowers, 30 yellow flowers and 15 purple flowers, whose sum equals 133 flowers, which is fewer than 150 flowers. [tex]\blacksquare[/tex]

Answer:

c. 4

Step-by-step explanation:

see how many cubes are already there. Then, subtract that answe from 12 to get how many you need.

Answer:

Count the units in total shown here:

There are 2 units both in the back and front.

So double of 2 means 4 units, there are 4 units on the back and front.

Now count the units between them:

There are 4 units across from them.

Add the units together:

4 + 4

= 8, there are 8 units in total shown in this figure.

But, we need to find how many more units should be added to these 8 units to get a result of 12 units altogether.

So, subtract the 8 units from the 12 units to get the remaining units you would need to add to 8 units to get 12.

12 - 8

= 4, you would need 4 more units so that this figure would have a volume of 12.
