b.
70.2 m
c.
42.6 m
d.
243 m

Answers

Answer:

b

Step-by-step explanation:

Let's find the area of the adjacent side.

Applying Pythagoras' Theorem,

(adjacent side)²= 18² -9²

adjacent side[tex] = \sqrt{243} [/tex]

adjacent side= 15.588 m (5 s.f.)

Area of triangle= ½ ×base ×height

Area of traingle

[tex] = \frac{1}{2} \times15.588 \times 9 \\ = 70.1m \: (nearest \: tenth)[/tex]

The nearest answer is B.

*If you rounded of to the nearest tenth for the adjacent side first then use the formula for area of traingle, the result would be exactly 70.2 m.

Quickly paying off debts and Having long-standing lines of credit.

What is Credit Score?

Based on information from your credit reports, a credit score predicts your credit behavior, such as how likely you are to repay a loan on time.

This is determined by the total amount you owe, the variety and quantity of accounts you have, and the ratio of your debt to your available credit.

Given:

As, Smaller amounts may boost your credit score if you make on-time payments, but larger balances and maxed-out credit cards will lower it.

So, Credit Score usually used to pay the debts.

Answers

Step-by-step explanation:

2/7= 0.3

5/7= 0.7

3

27/7= 3.9

4

29/7= 4.1

31/7= 4.4

please mark me brainliest

Step-by-step explanation:

you first change the mixed fractions to improper fractions

it now becomes 4 2/7 = 30/7 and 3 5/7 = 26/7

then you find the least common multiple of the denominators of the fractions

which is 7. because they all have a common denominator

Then, you divide 7 with the denominators, the answer you get multiply with the numerators

i.e 30/7 ÷ 7 = 1, 1 × 30 = 30

26/7 ÷7=1,1×26=26

31/7÷7=1, 1×31=31

29/7÷7=1,1×29=29

27/7÷7=1,1×27=27

from the answers above you arrange them in ascending order (least to highest)

To prove quadrilateral WXYZ is a parallelogram, Travis begins by proving △WZY ≅ △YXW by using the SAS congruency theorem. Which reasons can Travis use to prove the two triangles are congruent? Check all that apply.

WZ ≅ XY by the given.

Step-by-step explanation:

The option:

WX ≅ ZY by definition of a parallelogram

can't be used because we want to prove that WXYZ is a parallelogram

The Alternate Interior Angles Theorem states that, when two parallel lines (here XY and WZ) are cut by a transversal (here WY), the resulting alternate interior angles (here ∠ZWY and ∠XYW ) are congruent.

The reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself. Here,  WY ≅ WY.

Explanation:

these tables of values represent continuous functions. for which function will the y-value be the greatest for very large values of x

Answers

Answer:

Option A.

Step-by-step explanation:

We need to find a table for which the y-value will be the greatest for very large values of x.

From the given table it is clear that the largest value of x in all tables is 5.

In table A, y=64 at x=5.

In table B, y=32 at x=5.

In table C, y=40 at x=5.

In table D, y=13 at x=5.

It is clear that 64 is the greatest value among 64, 32, 40 and 13.

It means table in option A represents the function for which the y-value will be the greatest for very large values of x.

Therefore, the correct option is A.

The formula for the volume (V) of a pyramid is:

V = 1/3*B*h

where B is the are of the base and h is the height. We can isolate B, as follows:

multiply by 3 at both sides

V*3 = 1/3*B*h*3

divide by h at both sides

V*3/h = B*h/h

Step-by-step explanation:

Given the points J (1,-10) and K (7, 2)

From the section formula

[tex](x,y)=\left(\dfrac{mx_2+nx_1}{m+n}, \dfrac{my_2+ny_1}{m+n}\right)[/tex]

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is obtained using the formula:

[tex]y=\dfrac{my_2+ny_1}{m+n}\\m=5, n=1, y_1=-10, y_2=2\\Therefore:\\y=\dfrac{5*2+1*-10}{5+1}\\=\dfrac{10-10}{6}\\=0[/tex]

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

The y coordinate of the point that divides J to K in the ratio 5 : 1 is 0.

Distance

If a point O(x, y) divides the line segment AB with end points A(x₁, y₁) and B(x₂, y₂) in the ratio n:m, the coordinate of O is:

[tex]x=\frac{n}{n+m} (x_2-x_1)+x_1\\\\y=\frac{n}{n+m} (y_2-y_1)+y_1[/tex]

Let O(x, y) represent the point dividing J to K in the ratio 5 : 1. K(7,2) and J(1, -10)Hence:

[tex]y=\frac{5}{5+1}(2-(-10)) + (-10)=0[/tex]

The y coordinate of the point that divides J to K in the ratio 5 : 1 is 0.

The question is incomplete.

Complete Question

Correct 36.2598 to

a) to one decimal place.

b) To the nearest hundredth.

c) to nearest 0.001

d) to the nearest whole number

Answer:

a) to one decimal place = 36.3

b) To the nearest hundredth= 36.26

c) to nearest 0.001 = 36.260

d) to the nearest whole number = 36

Step-by-step explanation:

From the question, we are to round up 36.2598 to the following:

a) to one decimal place.

Rounding up 36.2598 to one decimal place means we are looking at the first number after the decimal which is 2. The number after it is 5, so we are adding one to 2. Hence,

36.2598 to one decimal place = 36.3

b) To the nearest hundredth:

Rounding up 36.2598 to the nearest hundredth means we are rounding up to 2 decimal places. This means we are looking at the second number after the decimal which is 5. The number after it is 9, which is higher than 5 so we are adding one to 5. Therefore,

36.2598 to the nearest hundredth = 36.26.

c) to nearest 0.001

Rounding up 36.2598 to the nearest 0.001 means we are rounding up to the nearest thousandth which is 3 decimal places.

This means we are looking at the third number after the decimal which is 9. The number after it is 8, which is higher than 5 so we are adding one to 9.

Therefore,

36.2598 to the nearest 0.001 = 36.260

d) to the nearest whole number

Rounding up 36.2598 to the nearest whole number means we are rounding up the number before the decimal place. That number is 6. We look at the first digit after the decimal, it is less than 5, 6 remains unchanged, if it is 5 and above, we add one to 6.

For our question, the number after the decimal is 2, it is less than 5 so 6 remains unchanged.

36.2598 to the nearest whole number = 36.

Answers

Answer: same. ( 6 degree )

Step-by-step explanation:

According to the question, An angle that measures 6° is drawn on a piece of paper. As you are looking at the angle through a×6 magnifying glass, which means it magnifies by a factor of 6 indeed. The length and the width of the shape may magnify by factor of 6, but the degree measure of the angle will remain the same.

Even if it is magnified by a factor of 100, the measure of the angle you see on the paper when you look through the magnifying glass will remain the same.

D)

Answers

Answer:

The expression with the described characteristics is: [tex]y = 3*(x - 8)^2 - 14[/tex]. Therefore the correct answer is letter D.

Step-by-step explanation:

I believe there is a typo in the vertex's coordinate, I think it should be (8,14). I came to this conclusion by observing the possible answers, if the given vertex is correct then there are no correct answers among them. I made my best effort to explain the question in a way that can be generalized for different vertex's coordinates.

The equations are given in their vertex form. This form has the following structure:

[tex]y = a*(x - h)^2 - k[/tex]

Where (h,k) are the vertex's coordinates, in our case (8, 14). This knowledge makes easier to determine a equation with the correct vertex as shown below:

[tex]y = a*(x - 8)^2 - 14[/tex]

Where the value of "a" must be determined by applying the given point.

[tex]13 = a*(5 - 8)^2 - 14\\13 = a*(3)^2 - 14\\a*9 = 27\\a = \frac{27}{9}\\a = 3[/tex]

The expression with the described characteristics is: [tex]y = 3*(x - 8)^2 - 14[/tex]. Therefore the correct answer is letter D.

Write the empirical formula A factory currently manufactures and sells 800 boats per year. Each boat costs $5,000 to produce. $4,000 of the per-boat costs are for materials and other variable costs, while the per-boat fixed costs (incurred on yearly rent, administrative, and other fixed costs) are $1,000. If boat orders increase to 1000 boats per year, how do per-unit costs change?
