You read online that a 15 ft by 20 ft brick patio would cost about $2,275 to have professionally installed. Estimate the cost of

pogonyaev

Answer:it will cost $1698

Step-by-step explanation:

You read online that a 15 ft by 20 ft brick patio would cost about $2,275 to have professionally installed. The area of the patio would be

15 × 20 = 300 square feet

It means that it costs $2275 to install 300 square feet of the patio professionally. Therefore, the cost of installing 1 square feet professionally would be

2275/300 = $7.58 per square feet

To estimate the cost of having a 14 by 16 ft, we would determine the total area.

Area = 16 × 14 = 224 square feet.

Therefore, the cost of installing 224 square feet professionally would be

224 × 7.58 = 1697.92

Approximately $1698

The blank of a number says how many times to use that number ia a multiplication

Evgesh-ka [11]

I'm pretty sure the answer is exponent since it tells you how many times to multiply the number beside it by itself.

Example:

${3}^{4}$
It is NOT 3 × 4 = 12

It is 3 × 3 × 3 × 3 = 9 × 3 × 3 = 9 × 9 = 81

I hope that helps you out!!

The value of m ∠ RPS is 64. 7°

<h3>What are collinear angles?</h3>

Collinear angles are angles formed when three or more points lie on the same straight line.

Note that angles on a straight line sum up to 180 degrees.

From the diagram given, we can see that the angles are collinear angles and thus sum up to 180 degrees;

m ∠QPS = 88°
m ∠ RPS = 5x + 34°
m ∠ QPR = 8x + 15°

m ∠QPS + m ∠ RPS + m ∠ QPR = 180°

88° + 5x + 34° + 8x + 15° = 180

collect like terms

5x + 8x = 180 - 137

Add like terms

13x = 43

Make 'x' the subject of formula

x = 43/ 7

x = 6. 14

m ∠ RPS = 5x + 34 = 5 ( 6. 14) + 34 = 30. 7 + 34 = 64. 7°

Thus, the value of m ∠ RPS is 64. 7°

If h(x)=(f o g) (x) and h(x)= ∛x+3, find g( x) if f(x)= ∛x+2 (picture attached)

Aleksandr-060686 [28]

Answer:

g(x) = x+1

Step-by-step explanation:

Informally, you can see that the function h(x) takes the root of a value that is 1 more than the value under the same radical in f(x). This suggests that adding 1 to x in f(x) will give you h(x). That is, ...

h(x) = f(x+1) = f(g(x))

so

g(x) = x+1

_____

More formally, you can apply the inverse of the function f(x) to the equation ...

h(x) = f(g(x))

f^-1(h(x)) = f^-1(f(g(x))) . . . inverse function applied

f^-1(h(x)) = g(x) . . . . . . . . . simplified

Now f^-1(x) can be found by solving for y in ...

x = f(y)

x = ∛(y+2) . . . . . . . . . definition of f(y)

x^3 = y+2 . . . . . . . . . cube both sides

x^3 -2 = y = f^-1(x) . . . subtract 2 from both sides

So, f^-1(h(x)) is ...

f^-1(h(x)) = g(x) = (∛(x+3))^3 -2 = x+3 -2

g(x) = x+1

Antonio finished the race in 28 minutes and 11.00 seconds. Julio finished 0.08 second faster than Antonio. Pete finished 0.1 sec

max2010maxim [7]

Answer:

It took Peter 28 minutes and 10.82 seconds to finish the race.

Step-by-step explanation:

We have that:

$t_{A}$ : Antonio = 28 min + 11.00 s (1)

$t_{J}$ : Julio = A - 0.08 s (2)

$t_{P}$ : Pete = J - 0.1 s (3)

Then, the time at which Pete finished the race is:

$t_{P} = t_{J} - 0.1$ (4)

By entering equations (1), (2), (3) into (4) we have:

$t_{P} = (t_{A} - 0.08) - 0.1$

$t_{P} = 28 min + 11.00 s - 0.18 s = 28 min + 10.82 s$

Therefore, it took Peter 28 minutes and 10.82 seconds to finish the race.

I hope it helps you!
