Answer:

There is no value of x to fit this requirement.

Step-by-step explanation:

The 2 perimeters in terms of x are:

4(x + 3) for the square and

2(x+1) + 2(x +4)  for the rectangle

and these need to be equal so

we equate these 2 and solve for x:

4(x + 3) = 2(x+1) + 2(x +4)

4x + 12 = 2x + 2 + 2x + 8

4x + 12 = 4x + 10

4x -  4x = 10 - 12

0 = -2   which is of course absurd so there is no solution to this equation.

Answer:

(x+3)•4=(x+4)•2+(x+1)•2

Step-by-step explanation:

4x+12=2x+8+2x+2

4x-2x-2x=-12+8+2

0=-2

this expression is indeterminate.

Answer:

x=30 is the answer no hate if I'm wrong :)

Step-by-step explanation:

The sum of angles in a triangle is 180 so we add them all and we get x=30.

Then find the measure of each angle by substitution.

Answer:

Distance of boat from Matt = 274.5 ft (Approx.)

Step-by-step explanation:

Given:

Height of cliff = 305 ft

Angle = 42°

Find:

Distance of boat from Matt

Computation:

Tan 42° = Distance of boat from Matt / Height of cliff

0.90 = Distance of boat from Matt / 305

Distance of boat from Matt = 274.5 ft (Approx.)

The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?

Answer:

Center Z score = 4.5

The score is unusual

Step-by-step explanation:

The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?

The formula for z score is:

z = (x-μ)/σ, where

x is the raw score = 6.9feet

μ is the population mean = 6feet

σ is the population standard deviation = 0.2 feet

Hence:

Z = 6.9 - 6/0.2

Z = 0.9/0.2

Z = 4.5

Yes this score is unusual

Answer:

slope = 6x

Step-by-step explanation:

the formula to find slope between 2 points is "m = (y2 - y1)/(x2-x1)", or "m = rise/run". so when you plug in the numbers, you get "m = (12 - 6)/(2 - 1)", which gives you "m = 6/1", which is just 6x.

Answer:

Slope = 6

Step-by-step explanation:

From the graph we get:

(x1, y1) = (1, 6) and

(x2, y2) = (2, 12)

Slope = (y2 - y1) / (x2 - x1)

= (12 - 6) / (2 - 1)

= 6 / 1

= 6

Answer:

Contraction

Expansion

Contraction

Step-by-step explanation:

The correct type of dilation for given scale factors are 1) contraction, 2) contraction, 3) expansion 4) contraction

Dilation is a type of transformation in geometry, in which the original figure changes its scales, either reduce or enlarge.

Given are scale factors,

Scale factor symbolized by k,

We know that, when k > 1, the figure expands or enlarge.

When k < 1, the figure reduces or contract.

And when k = 1, the figure is congruent to the dilation.

1) -5 = (contraction)

1 > -5, therefore, figure is contraction.

2) -1/4 = (contraction)

1 > -1/4, therefore, figure is contraction.

3) 3.5 = (expanding)

1 < 3.5, therefore, figure is expanding.

4) 6/7 = (contraction)

6/7 = 0.8571 < 1, therefore, figure is (contraction)

Hence,  -5 = (contraction),  -1/4 = (contraction),  3.5 = (expanding) and 6/7 = (contraction)

Answer:

a) c = 15t

Step-by-step explanation:

c = the total cost of the breakfast tickets

t = the number of breakfast tickets bought

Tickets for an all-you-can-eat pancake breakfast cost $15 each

Therefore, the equation that shows the relationship between c, the total cost of the breakfast tickets and t, the number of breakfast tickets bought is written as:

c = $15 × t

c = 15t

3rd choice

Step-by-step explanation:

The answer is the 3rd choice.

x cannot be 3 and 5 at the same time.

x = 3

x = 5

Subtract the first equation from the second equation.

x - x = 5 - 3

0 = 2

Since 0 = 2 is a false statement, there is no solution.

Solution :

Distance between two points =

√(3−3)^2+(7−1)^2=

Answer:

  3

Step-by-step explanation:

The average rate of change is the slope of the line between the points at the ends of the interval: (1, -2) and (3, 4). That is given by the slope formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -(-2))/(3 -1) = 6/2

  m = 3

The average rate of change on the interval is 3.

Answer:

39° = m∠A

51° = m∠B

Step-by-step explanation:

Complementary angles have a sum of their measures = 90

Let x = m∠B

then x + 12 = ∠A

m∠A + m∠B = 90

x + 12 + x = 90

2x + 12 = 90

2x = 78

x = 39° = m∠A

x + 12 = 39 + 12 = 51° = m∠B

The measure of ∠A is 39°.

The measure of ∠B is 51°.

Here,

The measure of ∠A is 12° greater than the measure of ∠B.

The two angles are complementary.

We have to find the measure of each angle.

What is Complementary angle?

Complementary angles have a sum of their measures is 90°.

Now,

The measure of ∠A is 12° greater than the measure of ∠B.

Let  m∠B = x

Then, ∠A =  x + 12

The two angles are complementary.

Hence,

m∠A + m∠B = 90

x + 12 + x = 90

2x + 12 = 90

2x = 78

x = 39°

And, x + 12 = 39 + 12 = 51°

Hence, The m∠A is 39° and m∠B is 51°.

Answer:

m<BOC = m<DOA= 115*

m<BOC + m<COD=180*

115* + m<COD + 180* ---> m<COD + 65*

m<COD +m<BOA + 65*

m<COD + m<DOA + m<AOB + m<BAC

m<BAC + 65* + 115* + 65* =245*

m<BAC = mBAC = 245*

Step-by-step explanation:

The measure of arc BAC of the circle O will be 245°.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

In circle O, the central angle ∠BOC has a measure of 115°.

The measure of arc BAC will be given as,

∠BOC + arc BAC = 360°

115° + arc BAC = 360°

arc BAC = 360° - 115°

arc BAC = 245°

The measure of arc BAC of the circle O will be 245°.

20 cents

Step-by-step explanation:

Assuming the cost of peanuts is 30 cents per ounce.

We have to find the cost of 1 pound of peanuts.

We know that,

1 pound = 16 ounces

$1 = 100 cents

Cost of 1 pound peanuts = 30 x 16

                                         = 480 cents = $4.80

Yes, $5.00 is enough to buy 1 pound peanuts.

Money left = $5- $4.80 = $0.20

Money left is equal to 20 cents.
