Answer: 52.5

Step-by-step explanation:

35 dollars 30% off is $24.5, 27 dollars 30% off is $18.90, and 13 dollars 30% off is $9.10 so all together it equals 52.5.

Answer: m<C= 31

Step-by-step explanation:

To find m<C: Since the triangles are equal, we know that (4x+10) is equal to 90. Then when you put them equal to each other and solve for x you get X=20. Then all you have to do is plug that x value (20) into the equation for the angle of C (x+11). Then you get that C=31 degrees.

Answer:

176x

Step-by-step explanation:

Step 1. Add the numbers

22x(4+3+1)

22x(8)

Step 2. Multiply the numbers

22x times 8= 176x

Answer: B) Linear; it can be written as y = -3x-6

We subtract 6 from both sides to go from the original equation to -3x-6 = y

Then we flip both sides to end up with y = -3x-6

This is in slope intercept form y = mx+b with m = -3 as the slope and b = -6 as the y intercept.

Answer:

A. $52,000

Step-by-step explanation:

The initial amount of the grant is $52,000. The correct option is a.

An annuity is a financial product that provides an individual with a series of regular payments in exchange for an initial investment or a series of payments.

Annuities are commonly used to generate income in retirement, but they can also be used for other purposes, such as covering the future expenses of a dependent or providing a guaranteed income stream for a set period of time.

We can use the formula for the present value of an annuity to find the initial amount of the grant:

PV = A * ([tex](1 - (1 + r)^{(-n)[/tex]) / r)

Where PV is the present value, A is the annual payment, r is the annual interest rate, and n is the number of periods.

Substituting the given values, we get:

PV = 12,177.17 x ((1 - [tex](1 + 0.055)^{(-5)[/tex]) / 0.055)

PV ≈ 51,765.57

Rounding to the nearest dollar, the initial amount of the grant is $52,000.

Therefore, the answer is option (a).

The value of the expression is 0.0009.

We have,

To explain the process of evaluating (0.03)², we need to understand the concept of exponentiation and how it applies to decimal numbers.

When we raise a number to the power of 2 (or square it), we are essentially multiplying the number by itself.

In this case, we are squaring the decimal number 0.03.

To calculate (0.03)², we multiply 0.03 by itself:

= 0.03 x 0.03

= 0.0009

In decimal form,

0.03 squared is equal to 0.0009.

This process follows the general rule of exponentiation, where raising a number to a power means multiplying the base number by itself the specified number of times.

In this case, we square 0.03 by multiplying it by itself once, resulting in 0.0009.

Thus,

The value of the expression is 0.0009.

Answer:

i.  y=2x

ii. y=x+6

iii. y=-2x-6

iiii. y=-4x+3

iiiii. y=4x-3

Step-by-step explanation:

You can find the slope of the line by putting y2-y1/x2-x1

All you have to do is choose 2 points. Y2 is the second number y and x2 is the second number x. Y1 is the first number y and X1 is the first number X. To find y-intercept you look on the table and see where X is 0 and Y is any number that is the y-int. For example 5 there is no X=0 on the table so you put it in the point slope formula which is y-y1=m(x-x1) where you use the points from the slope. You multiply m to x and m to x1 where you will end up with y-y1=mx+mx1 then you add the y1 to mx1 where you will get the y intercept

The triangles are similar, which means the corresponding angles are congruent. In this case, we can say angle K = angle Q. Note how K and Q are the second letters of JKL and PQR respectively. The order matters.

Because angle K = angle Q, we can use information from triangle JKL to get information about triangle PQR.

We can say the following:

cos(angle) = adjacent/hypotenuse

cos(K) = LK/JK

cos(K) = 5/13

so change the division sign to multiplication by flipping the divisor ( [tex]\frac{4}{5}[/tex] )

this means you now have 20 x [tex]\frac{5}{4}[/tex]

so you can simplify 20 and 4, this makes the 4 into a 1 and the 20 into a 5

you now have 5 x [tex]\frac{5}{1}[/tex]

The probability is 24.609%

The mathematical subject of probability deals with the outcomes of random events. The term "probability" refers to the possibility or chance of an outcome. It clarifies the likelihood of a particular occurrence. We use phrases like "It will probably rain today," "he will probably pass the test," "there is very little chance of getting a storm tonight," and "most probably the price of onion will go high again" all the time.

Given a coin is tossed 9 times, and to find the probability of exact four heads,

the probability for condition given by  binomial probability ⁿCₓ[(p)ˣ(q)ⁿ⁻ˣ]

where p is probability of tail = 1/2 (favorable outcome)

q is probability of head = 1/2: (1 - p)

n = total outcome = 9

x = 4

ⁿCₓ[(p)ⁿ(q)ⁿ⁻ˣ] = ⁹C₄[(1/2)⁴(1/2)⁵]

= [tex]\frac{9!}{4!(9 - 4)!}[/tex] [1/16 x 1/32]

= [tex]\frac{9 x 8 x7 x 6 x 5!}{4! x 5!}[/tex](512)

126/512 = 0.24609

= 24.609%

A circle with a 32 inch diameter has a central angle that intercepts an arc measuring approximately 75.36 inches. Which option describes how to determine this angles measure in radians?

A. Divide 75.36 by 16

B. Divide 75.36 by 32

C. Divide 16 by 75.36

D. Divide 32 by 75.36

Answer:

A. Divide 75.36 by 16

Step-by-step explanation:

The formula for Arc length is given as:

S = r θ

Where S = arc length

r = radius

We are told that:

Diameter of a circle = 32 inches

Radius of a circle = Diameter/2

= 32/2 = 16

Arc Length = 75.36 centimeters

The formula for Central angle =

θ = Central angle

θ = S/r

= 75.36/16

Option A is correct

The correct answer is option A. which is Divide 75.36 by 16

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.

The formula for Arc length is given as:

S = r θ

Where S = arc length

r = radius

We are told that:

Diameter of a circle = 32 inches

The radius of a circle = Diameter/2

r = 32/2 = 16

Arc Length = 75.36 centimeters

The formula for Central angle =

θ = Central angle

θ = S/r

θ= 75.36/16

Answer:

10a-16b+23

Step-by-step explanation:

First, you see what terms are alike. Then you add those like terms. For example with this expression, you add 7b+b+8b, resulting in 16b. If you are confused by the single b variable standing alone, there is basically a 1 in front of it, so you add it as 1b. 11 and 12 are like terms, for they don't have any variables attached to them. 10a stands alone because no other terms have an a variable. The simplified expression is 10a-16b+23.

Your welcome <3

The simplified value of the expression 10a - 7b + 11 + 8b - b - 12 is 1a - 1.

Given Expression:

10a-7b+11+8b-b-12

To simplify expression, first solve the like terms as

10a-7b+11+8b-b-12

= 10a -7b + 8b - b - 12 + 11

Now, -7b + 8b - b = -7b + 7b = 0

and, -12 + 11 = -1

Substituting the simplified value in 10a-7b+11+8b-b-12 gives

= 10a + 0 - 1

= 10a - 1

Answer:

The probability that 121 or more Americans in the survey are afraid to fly is 0.1335.

Step-by-step explanation:

Let X denote the number of Americans afraid to fly.

The proportion of Americans afraid to fly is, p = 0.10/

A random sample of n = 1100 Americans are selected.

The random variable X follows a Binomial distribution with parameters n = 1100 and p = 0.10.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

 [tex]np=1100\times 0.10=110>10\\\\n(1-p)=1100\times (1-0.10)=990>10[/tex]

Thus, a Normal approximation to binomial can be applied.

So,  [tex]X\sim N(np,\ np(1-p))[/tex]

Compute the probability that 121 or more Americans in the survey are afraid to fly as follows:

[tex]P(X\geq 121)=P(\frac{X-np}{\sqrt{np(1-p)}}>\frac{121-110}{\sqrt{99}})\\\\=P(Z>1.11)\\\\=1-P(Z<1.11)\\\\=1-0.86650\\\\=0.1335[/tex]

Thus, the probability that 121 or more Americans in the survey are afraid to fly is 0.1335.
