Answer:

18=x+3

-3      -3

15=x

so the answer is x=15

Step-by-step explanation:

Answer:

I think its 15 Im not a mathematician but Im pretty sure its 15

:)

Step-by-step explanation:

Answer:

I will answer in a general way because the options are not given.

We know that the area of model A is smaller than the area of model B.

For model A, we have 72 shaded sections, out of 100.

Then the quotient of model A is:

72/100 = 0.72

For model B we have 10 sections, and x shaded ones.

Because model B is greater than model A, we know that:

x/10 should be larger than 72/100

then we have the inequality:

x/10 > 0.72

x > 0.72*10

x > 7.2

And we can not have more than 10 shaded sections (because there is a total of 10 sections) then:

10 ≥ x > 7.2

Then x can be any whole number in that interval.

the possible values of x are:

x = 8

x = 9

x = 10

Answer:

F = -21

Step-by-step explanation:

the answer is f=-22

the reason is if you subtract 20 from both sides of the equation it will be

f+20=-1

f+20-20=-1-20

Answer:

$132

Step-by-step explanation:

264 divided by 8 = 33. 33 x 4 = 132

Answer:

132

Step-by-step explanation:

Total number of oranges = 264

Total number of oranges in each bag = 8

264 ÷ 8

= 33

33×4

= 132

Step-by-step explanation:

Answer:

Fs = 15 Hz > 12.7322 Hz

Hence, Nyquist theorem is NOT violated

Step-by-step explanation:

Given that;

a signal given by 15cos(20t) + 20sin(40t)

sampled at a rate of 15 Hz

Is the Nyquist theorem violated?

so;

from 15cos(20t) + 20sin(40t)

Freq F1 = 20/2π  Hz

F1 = 3.1830 Hz

and

Freq F2 = 40/2π

F2 = 6.3661 Hz

Now, Nyquist's rate FN ≥ 2 × F_max

FN ≥ 2 × 6.3661

FN ≥ 12.7322 Hz

Now our given signal was sampled at a rate of 15 Hz

so, Fs = 15 Hz > 12.7322 Hz

Hence, Nyquist theorem is NOT violated

Answer:

40 girls

Step-by-step explanation:

To get the number of girl students, we first do 48 divided by 6 to get 8. Then we do 8 x 5 to get 40.  

Answer:

[tex]y - 2 = -\frac{1}{3}(x + 3)[/tex]

Step-by-step explanation:

The equation of a line, in slope-intercept is given by:

[tex]y - y_0 = m(x - x_0)[/tex]

In which [tex](x_0,y_0)[/tex] is a point in the line and m is the slope.

We have these following points:

(-3,2), (0,1)

I am going to use [tex](x_0,y_0) = (-3,2)[/tex]

So

[tex]y - 2 = m(x - (-3))[/tex]

[tex]y - 2 = m(x + 3)[/tex]

Finding the slope

The slope, given two points, is given by the change in y divided by the change in x. In this question:

Points (-3,2) and (0,1).

Change in y: 1 - 2 = -1

Change in x: 0 - (-3) = 0 + 3 = 3

So

[tex]m = \frac{-1}{3} = -\frac{1}{3}[/tex]

So the equation of the line is:

[tex]y - 2 = -\frac{1}{3}(x + 3)[/tex]

Answer:

[tex]CSA = 660cm^2[/tex] --- Curved Surface Area

[tex]TSA = 968cm^2[/tex]  --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

[tex]h = 15[/tex] -- height

[tex]r = 7[/tex] --- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

[tex]CSA = 2\pi rh[/tex]

This gives:

[tex]CSA = 2 * \frac{22}{7} * 7 * 15[/tex]

[tex]CSA = 2 * 22* 15[/tex]

[tex]CSA = 660cm^2[/tex]

Solving (b): The total surface area (TSA)

This is calculated as:

[tex]TSA = 2\pi r(h + r)[/tex]

This gives:

[tex]TSA = 2 * \frac{22}{7} * 7 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * 22[/tex]

[tex]TSA = 968cm^2[/tex]

Answer:

4

Step-by-step explanation:

If you look carefully at the number line between -4 and -8 and see the line between the two, you can see that each mark is |2| apart.

If you go up from -4 to the blue dot, you go: -2, 0, 2, 4. There are 4 lines above from -4, so this matches.

Your answer is 4.

The quadrilateral LMNO is similar to the quadrilateral SRQP because the corresponding sides are in the same proportions option (B) is correct.

It is defined as the law to prove that the two figures have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.

It is given that:

The quadrilateral LMNO is shown in the picture

As we know from the similarity law, the ratio of the corresponding sides is in the same proportions.

Applying the similarity law in the quadrilateral LMNO and quadrilateral SRQP:

LM/PQ = MN/RQ = NO/RS = LO/SP

3/1.5 = 4/2 = 2/1 = 5/2.5 = 2

Thus, the quadrilateral LMNO is similar to the quadrilateral SRQP because the corresponding sides are in the same proportions option (B) is correct.

Answer:

The principal required to  accumulate interest of $ 1,008.00  on a rate of 4.5% per year for 7 years is $ 3200.

Step-by-step explanation:

Given:

Interest I = $ 1008

Time period t = 7 years

Rate of Interest per year r = 4.5% = 4.5/100 = 0.045

To determine:

Initial deposit P = ?

Using the simple interest formula

I = Prt

P = I / rt

P = 1008 / ( 0.045 × 7 )

P = $ 3200

Therefore, the principal required to  accumulate interest of $ 1,008.00  on a rate of 4.5% per year for 7 years is $ 3200.
