y

Answer:

r = 10

y = 11

Step-by-step explanation:

4y = 40 + 4

4(r + 1) = 40 + 4

4(r) + 4(1) = 40 + 4

4r + 4 = 40 + 4

4r + 4 = 44

4r + 4 - 4 = 44 - 4

4r = 40

4r ÷ 4 = 40 ÷ 4

r = 10

-----------------------------------------

y = r + 1

y = (10) + 1

y = 11

-----------------------------------------

4y = 40 + 4

4(11) = 40 + 4

4(11) = 44

44 = 44

Answer:

-2.8

Step-by-step explanation:

Given that:

Mean, μ = 78

Standard deviation, σ = 5

Omar's score, x = 64

The Zscore of Omar's score :

Zscore = (x - μ) ÷ σ

Zscore = (64 - 78) / 5

Zscore = - 14 / 5

Zscore = - 2.8

Hence, Omar's exam score is - 2.8

Answer:

-2.8 is correct

Answer:

[tex]x\geq -6[/tex]

Step-by-step explanation:

The domain of a function is all of the values that [tex]x[/tex] can be under that specific function. In this case, we're asking what values of [tex]x[/tex] allow [tex]\sqrt{\frac{1}{3} x+2}[/tex] to exist.

In order for square roots to exist, the quantity under the square root must be greater than or equal to [tex]0[/tex], because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for [tex]x[/tex]:

[tex]\frac{1}{3}x+2\geq 0[/tex]

Solving this inequality, we get:

[tex]\frac{1}{3}x+2\geq 0[/tex]

[tex]\frac{1}{3}x\geq -2[/tex] (Subtract [tex]2[/tex] from both sides of the inequality to isolate [tex]x[/tex])

[tex]x\geq -6[/tex] (Multiply both sides of the inequality by [tex]3[/tex] to get rid of [tex]x[/tex]'s coefficient)

Answer:

99.33ft^2

Step-by-step explanation:

The surface area of a square pyramid is expressed as;

TSA = a²+2a√a²/4 + h²

Given that

a = 5ft

h = 7ft

Substitute

TSA = 5²+2(5)√5²/4 + 7²

TSA = 25+10√25/4 + 49

TSA = 25 + 10√(221/4)

TSA = 25 + 10(√55.25)

TSA = 25 + 10(7.433)

TSA = 25 +  74.33

TSA = 99.33ft^2

Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2

Answer:5x5=25 fts

4(1/2 x 5ft x7 ft) = 70 fts

Add them up and you get

Answer= 95fts

have a nice day!!

I will do it in a way that can solve all these kinds of problem.

Of course, you can just substitute every possible answer in and see which one has the highest y value.

BUT I'm going to do this question by completing the square.

First organize the equation by decreasing degrees.

y=-16t^2+32t

Now factor out a -16 to make the x variable have no coefficient.

y=-16(t^2-2t)

Now complete the square.

y=-16(t-1)^2+16

By this if you graph it its the parent graph y=x^2, its a reflection over x axis by the negative sign at the beginning, then a vertical stretch by 16, and then go to the right by 1 then up by 16. This meant that the vertex is (0,0) go right 1 and up 16.

The vertex or the highest point of the graph is point (1,16) This also meant that its after 1 second at 16 feet height. The answer is B.

Answer:

4 m = width of the rectangle.

6 m = length of the rectangle

20 m = perimeter of rectangle

3 m = side of the square

Step-by-step explanation:

Let s = length of side of square

s + 1 = width of rectangle

s + 3 = length of rectangle

Area of rectangle = (s + 1)(s + 3)

Area of square = [tex]s^{2}[/tex]

So,  (s + 1)(s + 3) + [tex]s^{2}[/tex] = 33

[tex]s^{2}[/tex] + 4s + 3 + [tex]s^{2}[/tex] = 33

2[tex]s^{2}[/tex] + 4s - 30 = 0

2([tex]s^{2}[/tex] + 2s - 15) = 0

2(s + 5)(s - 3) = 0

s = -5   or   s = 3

Length of a side cannot be negative, so -5 is ignored

3 m = side of the square

4 m = width of the rectangle

6 m = length of the rectangle

2(4) + 2(6) = 8 + 12 = 20 m = perimeter of rectangle

Answer:

1,050 years

Step-by-step explanation:

A comet passes Earth every 70 years.

Another comet passes Earth

every 75 years

If both comets pass Earth this year, how many years

will it be before they both pass Earth on the same year again?

Find the lowest common multiple of 70 years and 75 years

70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,

75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350

Lowest common multiple of 70 years and 75 years is 1,050 years

Therefore,

If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

"The number of boys is 45 the number of girls,"

or to say,

"The ratio of the number of boys to the number of girls is 45:1."

This second interpretation reflects the fact that 45 is the unit rate (which is a number) for the ratio 4:5.

Answer:

The true statement of the area of the piece of land is;

(C) It is between 0.0007 and 0.007 square mile

Step-by-step explanation:

Using scientific notation, we have the value of a measurement presented as follows;

c × 10ⁿ = ce±n

Where;

c = The coefficient number, less than 10

en = 1 × 10⁺ⁿ

e-n = 1 × 10⁻ⁿ

Therefore, the given number, 7.4 e - 4, can be expressed as follows;

7.4 e - 4 = 7.4 × 10⁻⁴ = 0.00074

0.00074 ≈ 0.0007 and we have;

0.0007 < 0.00074 < 0.007

The correct option is therefore that it is between 0.0007 and 0.007 square mile

The statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074

The standard form for writing scientific notation is given as A * 10^n

Writing this as a standard value will give:

Hence the statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074
