a rectangular wall with a height of 7 1/2 ft has a perimeter of 46 ft. What is the area of the wall?

Answers

Answer:

116.25 ft²

Step-by-step explanation:

Height = 7.5ft

Perimeter : 2(7.5)ft + 2x ft = 46ft

Length = x ft

15+2x = 46ft

31 ft = 2x ft

x = 15.5 ft

7.5 x 15.5 = 116.25 ft²

Kayla is painting a room that is 12 feet long and 12 feet wide. The ceiling in the room is 8 feet high. The cost of painting the walls and door is $0.33 per square foot. The cost of painting the ceiling is $0.66 per square foot. Enter the cost, in dollars, for Kayla to paint the room.​

Answers

Answer: $221.76

Step-by-step explanation:

Each wall has a length of 12 and a height of 8 and there are 4 walls

(12 x 8) x 4 = 384 sq ft

multiply sq ft by cost ($0.33)

384 x 0.33 = $126.72 for the walls and door

The ceiling has a length of 12 and a width of 12

12 x 12 = 144 sq ft

multiply sq ft by cost ($0.66)

144 x 0.66 = 95.04

add the costs

126.72 + 95.04 = $221.76 total

A researcher studying microorganisms has discovered a strain of bacteria that doubles every 2.8 days. How many bacteria will the researcher have after 7.3 days if they started with 650 bacteria?

Answers

Answer:

3960.4 bacteria

Step-by-step explanation:

The formula to solve the above question is given as:

P(t) = Po (2) ^t/k

P(t) = Population after time t = ?

Po = Initial population = 650 bacteria

t = Time in days = 7.3 days

k = doubling time = 2.8 days

P(t) = 650 × (2)^7.3/2.8

P(t) = 650 × 2^2.6071428571

P(t) = 650 × 6.0929582599

P(t) = 3960.4228689 bacteria.

Approximately = 3960.4 bacteria

Therefore, the number of bacteria the researcher will have after 7.3 days if they started with 650 bacteria is 3960.4 bacteria.

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ 2: x^2+(y+4)^2=9}}}[/tex]

Step-by-step explanation:

The equation for a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where (h, k) is the center and r is the radius.

We know that the center of the circle is (0, -4) and the radius is 3. Therefore:

h= 0 y= -4 r=3

Substitute the values into the formula.

[tex](x-0)^2+(y--4)^2=(3)^2[/tex]

Solve the first parentheses.

(x-0)² = (x)²= x²

[tex]x^2+(y--4)^2=(3)^2[/tex]

Solve the next parentheses.

(y--4)² = (y+4)²

[tex]x^2+(y+4)^2=(3)^2[/tex]

Solve the exponent.

(3)²= 3*3=9

[tex]x^2+(y+4)^2=9[/tex]

This is the finished equation, which corresponds with number 2. Choice B (2): x²+(y+4)²= 9 is correct.

Answer:

Step-by-step explanation:

Step 1, Identify the coordinates of each vertices in the pre image

A ( -2 , 3 )

B ( 1 , 3 )

C ( 3 , -6 )

D ( -4 . -6 )

Step 2 apply dilation.

To apply the dilation we multiply the x and y values by the scale factor. ( assuming that the dilation is about the origin. )

The scale factor is 2 so we multiply the x and y values of the coordinates by 2, which is as simple as it sounds.

A ( -2 , 3 ) -------> A' ( -4 , 6 )

B ( 1 , 3 ) --------> B' ( 2 , 6 )

C ( 3 , -6 ) ---------> C' ( 6 , -12 )

D ( -4 , -6 ) ----------> D' ( -8 , -12 )

Hence the new coordinates are A' ( -4, 6 ), B' ( 2 , 6 ), C' ( 6 , -12 ), D' ( -8 , -12) Which corresponds with answer choice A

Answers

Answer:

27 feet

Step-by-step explanation:

Total distance from base of lamp to tip of shadow

15 + 8 = 23

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

tan∅ = opp/adj

opp will be the height of the lamp

adj is 23

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

tan 50 = opp/23

multiply both sides by 23

23 * tan50 = opp

Use calculator

27.4 = opp

Answers

Answer:

The answer is 94.5

Step-by-step:

This is actually quite simple. Although, in order to do this you will need a calculator. First, you identify which trigonomic function you will use in order to find the value of x. for this problem you need to use the COS function. The equation for this is COS67= 67/x. Because you are trying to find x you would multiply each side by x. now the equation is xCOS67= 67. because you still can't find the value of x by doing this you will need to get x by itself. To get x by itself divide each side by COS67. the equation is now x= 94/ COS67. This is where the calculator comes in. On the calculator enter 94 divided by 67 then COS function. This gives you the measure of RS.
