Hii!

___________________________________________________________

Answer:

$\sf 48\textdegree$

Step-by-step explanation:

The sum of complementary angles is always 90 degrees.

We can find the complement of 90 by setting up an equation; (let x be the unknown angle).

$\implies$ 42+x=90

Subtract 42 from both sides

x=48

Hope that this helped! Best wishes.

How does f(x) =8(x) chAnge over the interval from x=1 to x=2

Tju [1.3M]

Answer:

Step-by-step explanation:

Given,

f(x) = 8(x)

To value of a function at any point can be calculated by substituting that value in place of x.

Therefore,

f(1) = 8(1) = 8

f(2) = 8(2) = 16

The change over the interval from x=1 to x=2 can be calculated using $\frac{f(2) - f(1)}{2-1}$

=> $\frac{16 - 8}{1}$

=> 8

Answer:

392 ft²

Step-by-step explanation:

Break this area into two parts, that is, into two trapezoids. The first trapezoid, on the left, has length 8 ft and average length (30 ft + 27 ft)/2, so its area is (8 ft)(28.5 ft) = 228 ft ².

The second trapezoid has width 8 ft and average length (19 + 22)/2 ft, or 8 ft by 20.5 ft). The area of this part is 164 ft².

Thus, the total area is 164 ft² + 228 ft², or 392 ft²

A real estate agent has 18 properties that she shows. She feels that there is a 40% chance of selling any one property during a

algol13

Answer:

Probability of selling no more than 3 properties in one week is 42%

Step-by-step explanation:

With 18 properties to sell and 40% chance of selling any one, it means that she can sell 7.2 properties (18 x 40%) in a week.

To sell no more than 3 properties in one week, the probability will be 3/7.2 x 100 = 0.4167

Probability is the chance of one event taking place out of many events. It is calculated as the number of the one event taking place divided by the total number of events. It is expressed in decimal or percentage form.

Find the exact valueFind sin theta:/2<br> See picture. Show steps

ddd [48]

Answer:

Step-by-step explanation:

Use the half angle formulas

sin(θ/2) = ±√((1 - cosθ)/2)

sin(θ/2) = ±√((1 - (3/5))/2)

sin(θ/2) = ±√((2/5)/2)

sin(θ/2) = ±√(1/5)

knowing θ is in the 4th quadrant, θ/2 will be in the second quadrant where sines are positive.

sin(θ/2) = +√(1/5) = √0.2

Each hotdog cost $1.50 and sodas cost $.50. At the end of the day you made a total of $78.50.You sold a total of 87 hot dogs and

Maru [420]

Answer:

35 hotdogs and 52 sodas were sold.

Step-by-step explanation:

Create equations to represent the problem.

let "d" be the number of hotdogs sold

let "a" be the number of sodas sold

1.5d + 0.5a = 78.50 Equation for money made

d + a = 87 Equation for items sold

Rearrange d + a = 87 to isolate one of the variables.

a = 87 - d

Substitute a for 87-d into the other equation. Isolate using reverse operations.

1.5d + 0.5a = 78.50

1.5d + 0.5(87 - d) = 78.50 Distribute over brackets by multiplying

1.5d + 43.5 - 0.5d = 78.50 Collect like terms

43.5 + d = 78.50 1.5d - 0.5d is 1d. You don't need to write "1".

43.5 + d - 43.5 = 78.50 - 43.5 Isolate d, subtract 43.5 from both sides

d = 35 Number of hotdogs sold

Substitute d for 35 in the simpler equation

d + a = 87

35 + a = 87 Subtract 35 form both sides to isolate "a".

a = 87 - 35

a = 52 Number of sodas sold

Therefore 35 hotdogs and 52 sodas were sold.
