PLZZ MARK BRAINLIEST!!!

Answer:

64.2

Step-by-step explanation:

Use tan to find the measure of x.

tan = 0pposite/adjacent

opposite = 29

adjacent = 14

so:

[tex]tan(x)=29/14\\x = tan^{-1} (29/14)\\x = 64.2[/tex]

Answer:

x = 64.2°

Step-by-step explanation:

tan x° = 29/14

14 · tan x° = 29

tan x° = 29/14

arctan(x) = 64.2°

Answer:

83.8

Step-by-step explanation:

first you add the grades together: 75 + 87 + 90 + 88 + 79 = 419

then you divide by the amount of grades: 419 / 5 = 83.8

Answer:

0.020

Step-by-step explanation:

Given that,

μ = 17,

σ = 0.7,

x¯ = 16.7 hours

n(number of batteries) = 30

To find,

The probability(e) by using μ\frac{σ}{[tex]\sqrt{n}[/tex]} = normal cdf

∵ (E - 99, 16.7 , 17, 0.8/[tex]\sqrt{30}[/tex])

The probability of getting a random sample of 30 batteries = 0.020

Hence, the claim is reasonable as only 2% of batteries are likely to last till 16.7 hours.

Answer:

Step-by-step explanation:

The solution is, The area of Rhombus B is 9 times bigger than the area of Rhombus A.  The reason is that 2 dimensions were tripled, so x3 x3 = 9 times bigger.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

Rhombus A:

Area = 35 square inches

base = 7 inches

height = 5 inches

Rhombus B:

Area = 315 square inches

base = 21 inches (7 x 3)

height = 15 inches (5 x 3)

A = 21 x 15

so, we get,

The area of Rhombus B is 9 times bigger than the area of Rhombus A.  The reason is that 2 dimensions were tripled, so x3 x3 = 9 times bigger.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The number of quarters = 1

So , the value of quarters = $ 0.25

The number of cents = 2

So , the value of cents = $ 0.20

The number of nickels = 2

So , the value of nickels = $ 10

And , the equation will be

A = value of quarters + value of cents + value of nickels

On simplifying , we get

A = 0.25 + 0.20 + 0.10

A = $ 0.55

Therefore , the value of the coins is A = $ 0.55

Hence , the equation is A = $ 0.55

Answer: D, C, A

Step-by-step explanation:

An exterior angle is an angle that is supplementary to an interior angle.

The angle between the extended side and its adjacent side is called the exterior angle so the option (D), (C), and (A) will be the correct answers.

Exterior angles become by a side of that figure and its extended adjacent side.

The exterior angle has been attached.

Since in the graph angle, ∠3 become by two extended lines but for exterior angle, there should be only one extended line which is ∠6, ∠5, and ∠2.

Hence angles ∠6, ∠5, and ∠2 will be the exterior angles.

Answer:

5.1%

Step-by-step explanation:

We are told that 30 shares of Stock are purchased for $15/share..

This gives a total value of: 30 × 15 = $450.

Now,they are sold for $480 with a commission of $6. This means the final money getting to the seller is; 480 - 6 = $474.

Thus; rate of return percentage = (474 - 450)/474) × 100% = 5.06%

To the nearest tenth gives; 5.1%

The rate of return is 5.1%.

Given that,

Based on the above information, the calculation is as follows:

The total value should be

[tex]= 30 \times 15[/tex]

= $450.

Since it is sold for $480 along with commission of $6 so final money should be  

= 480 - 6

= $474.

Now rate of return is

[tex]= ((474 - 450)\div 474) \times 100%[/tex]

= 5.06%

= 5.1%

Step-by-step explanation:

Yes the solution to p/9 = 7 is 63.

Answer:

c

Step-by-step explanation:

I think

The points that could be on the line

y = 7x - 16 are (-2, -30)

-30 = 7 X -2 - 16

-30 = -14 - 16

-30 = -30

Option B is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A line has a slope = 7 and passes through the point (3, 5).

Now,

The equation of a line can be written as,

y = mx + c

m = 7

y = 3x + c

Now,

(3, 5) = (x, y)

5 = 7 x 3 + c

5 = 21 + x

5 - 21 = c

c = -16

The equation of the line.

y = 7x - 16

The points that could be on the line have to satisfy the equation.

y = 7x - 16

A.

(-1, -24)

y = 7 x -1 - 16 = -7 - 16 = -23

This is not true

B.

(-2, -30)

y = 7 x -2 - 16 = -14 - 16 = -30

This is true.

C.

(6, 24)

y = 7 x 6 - 16 = 42 - 16 = 26

This is not true.

D.

(10,55)

y = 7 x 10 - 16 = 70 - 16 = 54

This is not true.

Thus,

The points that could be on the line

y = 7x - 16 are (-2, -30)

-30 = 7 X -2 - 16

-30 = -14 - 16

-30 = -30

Option B is the correct answer.

3t + 7 = 2 + 5t

Step 2: Solve for t

Answer:

Explanation:

3t + 7 = 2 + 5t

3t + 7 = 5t + 2

3t + 7 − 5t = 5t + 2 − 5t

−2t + 7 = 2

−2t + 7 − 7 = 2 − 7

−2t = −5

Divide both sides by -2

−2t / -2 = −5 / -2

t = ⁵⁄₂

t = 2.5

t = ⁵⁄₂ or 2.5
