Can someone verify if this is correct

The two angles form a right triangle which is 90 degrees.

Add the two to equal 90:

3x-8 + 4x = 90

simplify:

7x-8 = 90

Add 8 to both sides:

7x = 98

Divide both sides by 7:

x = 14

Answer:

Step-by-step explanation:

Given the sequence

2, 8, 32, 128..

The sequence is a geometric sequence. The nth term of the geometric sequence is expressed as;

Tn = arⁿ⁻¹

a is the first term

r is the common ratio

n is the number of terms

From the sequence;

a = 2

r = 8/2 = 32/8 = 4

n = 11 (since we are to find the 11th sequence)

Substitute into the formula;

T₁₁ = 2(4)¹¹⁻¹

T₁₁ = 2(4)¹⁰

T₁₁ = 2(1,048,576)

T₁₁ = 2,097,152

Hence the 11th term of the sequence is 2,097,152

Answer:

Approx 24 apples.

Step-by-step explanation:

So, you have $28. 1st find out how much a lb. of apples cost. So divide 7/2 to get $3.50. A pound of apples cost $3.50. After that divide 16oz(1 lb) by 5 oz. to get 3.2. So you can get approx 3 apples for the price of $3.50. With $7 you get 6 apples. For 2 more pounds, that'd be 12 with only $14 spent. For another 2 that'd be 18 with $21 spent. For another 2 that'd be 24 with $28 spent.

Answer:

D. No, because the given numbers do not satisfy the equation a² + b² = c²

Step-by-step explanation:

For the set of numbers; 24, 20, 32, to form a pythagorean triple, they must satisfy the equation a² + b² = c².

Where, c is the longest side (hypotenuse), while a and b are the two other legs.

Let's find out.

a = 20, b = 24, c = 32

Plug in the value into the equation

20² + 24² = 32²

976 = 1,024 (this is not true).

976 is not equal to 1,024.

The set of given numbers does not form a pythagorean triple because it does not satisfy the equation a² + b² = c².

I have gotten 50$ for mowing the lawns. First you would want to subtract $99.99 with how much money you have without the money of mowing the lawn. Then you would have to get the answer of $27.50. Lastly, you would need to add up the money you have left and the money you end with after buying the shoes and get $50. So this means that I got $50 for mowing the lawn.

You earned a total of $50 by mowing the lawn.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is that you have $73.50. You earn additional money mowing the lawn. You decide to purchase some shoes that cost $99.99 and you have $23.51.

Assume that the money you earned by mowing lawn is $x. Then, we can write -

(73.5 + x) - 99.99 = 23.51

x + 73.5 - 99.99 = 23.51

x - 26.49 = 23.51

x = 50

Therefore, you earned a total of $50 by mowing the lawn.

Answer:

b

Step-by-step explanation:

The probability for P(X<$400) is 0.7881.

The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean. In essence, standard deviation represents the degree of variability present in a given data collection.

Given:

Mean = $360

Standard Deviation = $50

We can use the z-score formula that is shown below:

Z = x - μ/σ

Where,

Z = standard score

x = observed value

μ = mean of the sample

σ = standard deviation

So,

z = 400 - $360/$50

z = 40/ 50

z= 0.8

and, P(x<400) = 0.78814

Scalene

Step-by-step explanation:

It is not isosceles because an isosceles triangle needs to have at least 2 congruent sides

It is not equilateral because not all of the sides are the same length

It appears to be a right triangle, not an acute triangle

The answer is scalene because all sides are a different length

Answer:

  -10f -6

Step-by-step explanation:

Maybe you want to simplify the expression ...

  3(-3f-2)-f

The distributive property is used to eliminate parentheses.

  = 3(-3f) +3(-2) -f

  = -9f -6 -f

Recognize like terms and group them together to make it easier.

  = -9f -f -6

Combine the like terms.

  = (-9 -1)f -6

  = -10f -6

Answer:

Susana will have 107 students.

Step-by-step explanation:

Becca have students = 115

We can write its as:

Becca has 115 students, so Susana will have 115-8 = 107 students

Because fewer means less than so, 8 less than 115 is 115-8

We can write it as:

Susana has 107 students, so Erika will have: 107+25 = 132 students.

because more means we need to add 25 students with number of students in Susana class.

So, Susana will have 107 students.

Answer:

17abc

Step-by-step explanation:

To find the greatest common factor between 17abc and 51a²bc, let's start by breaking down any composite number here into prime factors. 17 is prime, but 51 is composite; its prime factorization is 3 · 17. Now, let's fully expand each term:

[tex]17\cdot a\cdot b\cdot c\\3\cdot17\cdot a\cdot a\cdot b\cdot c[/tex]

The greatest common factor is the product of all the factors these terms have in common. Here, we can see that they have

in common. Multiplying these together, the greatest common factor is 17abc.

Answer:

$60 in total

Step-by-step explanation:

You find the amount to give for the tip first:

An easy way of doing percent's is getting 10% of a number. 10% of $50.00 you simply move the decimal to the left one time.

You would end up with $5.00 being 10% of $50.00.

Since you want 20% of $50.00 you would just simply multiply $5.00 (10% of $50.00) by 2. (2 * 10% = 20%).

This gives you $10.00.

By knowing 20% of $50.00 is $10.00 you then want to find the grand total you would have to spend in all so you add $10 to the $50 bill giving you a total of $60.00.

Answer:

60.00

Step-by-step explanation:

so you're doing 50.00 plus another 20% since you/re tipping the waiter which gives you a total of 60.00

Answer:

Y=x+-5

Step-by-step explanation:

The equation of line that passes through the slope -5 and  through the origin is y=-5x.

Given that, the slope of a line is -5 and it passes through the origin.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Substitute m=-5 and (x, y)=(0, 0) in y=mx+c, we get

0=-5(0)+c

c=0

Put m=-5 and c=0 in y=mx+c, we get

y=-5x

Therefore, the equation of line that passes through the slope -5 and  through the origin is y=-5x.

Answer:

You could pick as many as you like. Ideally you would use all the leaves on the tree, but that would be rather a large number to measure, and your parents might not be very happy if you stripped the tree bare!

So let's try 100 leaves.

How to get a random sample?

Here is one way you could get a random sample:

Try taking all the leaves on one branch of the tree. After you've discarded any that are broken, then see how many there are. If there are less than 100, then get the leaves from another branch until you have more than 100. Then write a different number (starting with 1) on each leaf with a marking pen.

Write the same numbers on small pieces of paper.

Fold the pieces of paper.

Put them into a hat and mix them up.

Draw 100 pieces of paper (without looking) from the hat. The first 100 pieces of paper you draw would give you the numbers of the leaves to use in the experiment.

The next thing you need to decide is how to measure the leaves, and

how accurate your measurements should be:

How to measure?

Keeping your leaves flat, use a ruler to measure the length of each leaf from the pointy part at one end of the leaf to the point where the leaf joins the stalk at the other end. Maybe your leaves bend a bit, but don't follow the main rib of the leaf as this would make measurement too difficult.

Just measure in a straight line as shown in the following diagram:

leaf

How accurate?

You should measure the length of each leaf to the nearest millimeter.

Now you're ready to begin.

Measure the length of each leaf to the nearest millimeter and record you results in a table, as follows:
