Two angles that are supplementary have a ratio of 7 to 5. what are their measurements?

Answers

Answer 1

7x + 5x = 180
12x = 180
x = 15
Therefore, the 2 angles equal (7*15) and (5*15) which equals
105 degrees and 75 degrees

Answers

First you would use the distributive property to multiply each term in the parentheses by 2. You should get something like this:
2x + 12 + 3x + 4
Next, combine all like terms (terms with x, and terms without x).
5x + 16
That is the final answer, because it cannot be simplified any further. Hope this helps!

1/3 of birds egg hatch in two eggs hatch how many eggs did the bird lay

Answers

6 eggs because 1/3 is 2.
2/3 is 4.
3/3 is 6.

Hope this helped☺☺

The total number of eggs a bird laid is 6 eggs.

To solve this problem we need to break it down step by step:

Assuming 1/3 of the eggs hatch means 2 eggs hatch, so if two eggs hatch, this represents 1/3 of the total eggs laid.

To find the total number of eggs the bird laid, we need to find the equivalent of 1 whole (the total). If 1/3 is equal to 2 eggs, then the whole (3/3 or 1) would be 6 eggs.

Answers

I think these are the answers for a and b

a) = -2

Choose the equation of the vertical line passing through the point (-2, 3). A vertical line goes up and down through point (-2, 3), so every point on the line will have the same x coordinate. For example, (-2, 0) and (-2, 1) and (-2, -1) all fall on that vertical line. Therefore, the equation for the line is x = -2 Choose the equation of the horizontal line that passes through the point (-5, 1). A horizontal line goes left and right through point (-5, 1), so every point on the line will have the same y coordinate. For example, (-1, 1) and (0, 1) and (1, 1) all fall on that horizontal line. Therefore, the equation for the line is y = 1.

What is the length of ST, to the nearest tenth of a yard?

Answers

Let's say that ST is side b
Use the Law of Sines to find side b.
b / sin(B) = a / sin(A)
b / sin(59°) = 7 / sin(79°)
b = (sin(59°) x 7) / sin(79°)
b = 6.112

That is answer B.) 6.1 yards

Hope this helps!

Answer: Second Option is correct.

Step-by-step explanation:

Since we have given that

ΔSRT is a triangle with measures :

SR = 7 yd

∠T = 79°

∠R = 59°

We need to find the side ST say x.

We will use " Law of Sines " :

[tex]\frac{\sin T}{SR}=\frac{\sin R}{ST}\\\\\frac{\sin 79^\circ}{7}=\frac{\sin 59^\circ}{x}\\\\0.14=\frac{\sin 59^\circ}{x}\\\\x=\frac{\sin 59^\circ}{0.14}\\\\x=6.12\ yd[/tex]

Hence, the length of ST = 6.1 yd.

Therefore, Second Option is correct.

A regular hexagon has a perimeter of 120 m. Find its area. Leave your answer in simplest radical form.

Answers

To find the area of any regular shape, its formula is

(1/2) • a • p

Where a is the apothem (a line from the center of a side to the center of the shape) and p is the perimeter.

We have the perimeter: 120

Now to find the apothem. To find it, we’re going to cut any sidelength in half, and the line from that half to the center of the hexagon will form a right triangle. We know the bottom leg (where the shape is) is 10 (since 120/6 = 20, and we cut that in half). All we need is angles. To find the interior angle of any regular shape, we use

(180(n - 2))/n

Plugging in, we get 120 degrees for every side. Since we cut it in half, then the top angle of our right triangle is 60. You know what that means? We’ve just found a 30, 60, 90 triangle.

Using the laws of this special triangle, the length of the apothem is the shortest leg times sqrt(3)

So, 10sqrt(3) is your apothem.

Plug everything in!

(1/2) • a • P

(1/2) • 10sqrt(3) • 120

Your area is 600sqrt(3)

Trey wants to plant grass in his backyard. His backyard is in the shape of a rectangle. Its length is 31
feet and its width is 24
feet. Suppose each pack of seed covers 12
square feet. How many packs of seed will he need to cover the backyard?

Answers

Find the total area of the yard in feet.

Area of a rectangle is length x width.

31 x 24 = 744

Divide the total area of the yard by the coverage of the seeds.

744/12 = 62

He will need 62 packs of seed.

Final answer:

To find out how many packs of seeds Trey needs, we need to first determine the area of his backyard which is 744 square feet. Each pack of seed cover 12 square feet. Therefore, dividing the total area by the area a pack of seed covers, we find that he needs 62 packs of seeds.

Explanation:

The subject of this question is Mathematics. Specifically, it involves the concept of area and multiplication, commonly taught in middle school. Trey's backyard is in the shape of a rectangle, and we know that the area of a rectangle is calculated by multiplying its length by its width. In this case, the length is 31 feet and the width is 24 feet. Multiplying these numbers gives us a total area of 744 square feet.

Each pack of seed covers 12 square feet. So, to figure out how many packs Trey needs, we would divide the total area by the area each pack covers. Dividing 744 by 12 gives us 62, which means Trey will need to buy 62 packs of seeds.

A small software company has two customer service representatives.The supervisor of he customer service department determines that there is an 85% probabiiy that a customer sevice representative will e on the phone with a customer at any given time. what is the probability o both representatives being on the the phone at the same time?,

Answers

To find the aggregate probability of two independent events occurring, we multiply the independent probabilities together. So, if the chance of each agent being on the phone is 0.85, then we multiply 0.85*0.85 to find the chance of them both being on the phone. Doing with, we find that there is a 72.25% probability of both of the agents being on the phone simultaneously.

Answer:

The probability that both customer representatives are on the phone at the same time is 72.25%.

Step-by-step explanation:

Consider the provided information.

There is an 85% probability that a customer service representative will be on the phone with a customer at any given time.

There are 2 customer service representatives.

To find the probability that both customer representatives are on the phone at the same time, we multiply the independent probabilities together.

0.85×0.85=0.7225

Hence, the probability that both customer representatives are on the phone at the same time is 72.25%.

At a sale, books are sold at $90.75 each, which is 75 percent of the original price. What is the original price

Answers

[tex] \frac{75}{100} = \frac{90.75}{x} \\ x = \frac{90.75 \times 100}{75} = \frac{9075}{75} = 121[/tex]
the answer is 121

Final answer:

To find the original price of the book, we can set up an equation: 0.75x = $90.75. Solving for x, we find that the original price is $121.

Explanation:

To find the original price of the book, we can set up an equation. Let's denote the original price as x. The sale price is 75% of the original price, which can be expressed as 0.75x. We are given that the sale price is $90.75, so we can set up the equation:

0.75x = $90.75

To solve for x, we divide both sides of the equation by 0.75:

x = $90.75 / 0.75

Using a calculator, we can calculate that the original price of the book is $121.

Just took this quiz so here are the right answers:
1.) Henry- $578
2.) Karen- $25.33
3.) Nikos- $61,980
Hope it helps!(:

Answer:

1: B) $578

2: B) $25.33

3: D) $61,980

Step-by-step explanation:

1) Henry's premium = ($100,000 / $1,000) x $5.78 = $578

2) Karen's total premium = ($75,000 / $1,000) x $17.56 = $1,317

if she is paid weekly, then the premium must be divided by 52 weeks = $1,317 / 52 weeks = $25.33 deducted per week

3) Nikos's premium per year = ($300,000 / $1,000) x $10.33 = $3,099

times 20 years = $3,099 x 20 = $61,980

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The expression is given in the question as:

-18a⁻² b⁵/-12a⁻⁴ b⁻⁶

To find the equivalent expression for -18a⁻² b⁵/-12a⁻⁴ b⁻⁶, we need to combine the constants and factors that have the same base and exponent.

You can begin by combining the constants in the fraction: -18/-12 = -3/2.

Next, you can simplify the terms involving the variables. Recall that when you divide two powers with the same base, you subtract the exponents. Therefore, you can simplify the expression as follows:

(-3/2)(a⁻² ÷ a⁻⁴ (b⁵ ÷ b⁻⁶)

= (-3/2)(a⁻⁴ a⁴) (b⁵ b⁶)

= (-3/2)(a²)(b¹¹)

= (-3/2)a²b¹¹

This is the simplified form of the given expression.

Hence, the correct answer would be option (C)
