Answer 1

The correct answer is B

Answer 2

Answer:

Let the required angles be 7x and 11x

According to the above problem,

[tex]7x + 11x + 90 = 180 \\ 18x = 90 \\ \boxed{ x = 5}[/tex]

★1st angle= 7x= 35°

★2nd angle=11x= 55°

★3rd angle is 90°

2. 35°,55°,90° is the right answer.

How do you solve equations using Substitution.

Answers

Substitution is one of the methods for solving linear equations. It is a good choice if there is a variable with a coefficient of 1. This method involves solving one of the equations for a variable and then substituting that expression into another equation to solve for another variable. This will produce a single equation with one variable, which can then be solved algebraically.

Answers

Answer: The acceleration is 0 after 4.5 seconds.

*The distance traveled in the last 15 seconds on the graph is about 225 meters.*

If the question means "distance traveled during the last 15 seconds before coming to a complete stop" The distance is 30 meters.

The attachment shows what I believe to be the missing right side of the graph showing the velocity at 0.

Step-by-step explanation: a.) at 4.5 seconds, the graph is momentarily flat; that is, the derivative, (the change in slope) is 0. There is no change in velocity at that point. Before that, the velocity is increasing, so there is positive acceleration. After that, the velocity is decreasing. So the acceleration is negative.

*The answer choices seem incorrect to me. for part b. Is there a typo?*

b.) From 10 seconds to 25 seconds, the "last 15 seconds" on the graph, the velocity is decreasing at a steady rate; the average velocity is 15m/sec

At 15m/sec × 15 sec, the distance traveled is 225 meters.

If we are to extrapolate to the point there the velocity is 0, assuming the steady rate of deceleration, the motorbike will reach that stopping point at 63.75 seconds. At 15 seconds before that, at 48.5 sec, it is traveling at 4m/sec.

The average velocity during the final 15 seconds is 2m/sec.

2m/sec × 15 sec = 30 meters.

I don't see that choice either, so I wonder if the question is missing something.

If someone else has a better explanation, I hope they they will answer and explain what I missed.

Which pair of factors of 30 has a sum of -17?

Answers

Answer: 30 = 1 x 30, 2 x 15, 3 x 10, or 5 x 6. Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30. Prime factorization: 30 = 2 x 3 x 5.

Step-by-step explanation:

The pair of factors of 30 which has a sum of -17 is -2 and -15.

What are Factors?

Factors of a number or an algebraic expression are the numbers or expressions which divides the given number evenly.

For example, 10 = 2 × 5

So we can say that 2 and 5 are factors of 10.

We have to first find the factors of the number 30.

Pair of numbers which on multiplication gives 30.

2 × 15 = 30

-2 × -15 = 30

3 × 10 = 30

-3 × -10 = 30

5 × 6 = 30

-5 × -6 = 30

The numbers which has the sum of -17 are -2 and -15.

Hence the pair of factors which has a sum of -17 are -2 and -15.

Bonnie deposited $1000 in an investment account on the first of January in 2001. The account pays 7.2% interest compounded annually. How much is the investment worth at the end of 2005? please help, having a mental break down over my math homework <3

Answers

Answer:

About $1415.71

Step-by-step explanation:

We can use the formula for compound interest, given by:

[tex]\displaystyle A=P(1+\frac{r}{n})^{nt}[/tex]

Where P is the initial amount, r is the rate, n is the number of times compounded annually, and t is the time in years.

Our initial amount is the $1000 Bonnie deposited. So, P = 1000.

Our rate is the interest, which is 7.2% of 0.072. So, r = 0.072.

Since it is compounded annually, our n = 1. So, we have:

[tex]A=1000(1+0.072)^t[/tex]

We want the amount after 5 years. So, t = 5. Substitute and evaluate:

[tex]A=1000(1.072)^5\approx\$1415.71[/tex]

The investment will be worth about $1415.71 after 5 years.

AB is a chord of length 3 inches in a circle of radius 2.5 inches. Find the distance of AB from the center of the circle.

Answers

Answer:

2 inches

Step-by-step explanation:

Given that:

|AB| = 3 inches

Let the radius be |AC| where C is the center of the circle.

The distance from C (center of the circle) to where it cuts the line AB(chord) is required to be determined.

So, let that point on line AB be point D.

Then, |CD| from the center of the circle can be figured out by using the Pythagoras rule.

i.e.

AC² = AD² + CD²

2.5² = 1.5² + CD²

6.25 = 2.25 + CD²

6.25 - 2.25 = CD²

4 = CD²

CD = √4

CD = 2 inches

One laundry detergent is 15% bleach and another is 40% bleach. How many ounces of each detergent must be used to make 48 ounces of a detergent that is 23% bleach?

Answers

Answer:

32.64 ounces of a detergent that is 15% bleach was mixed with 15.36 ounces of a detergent that is 40% bleach to get 48 ounces of a detergent that is 23% bleach.

Step-by-step explanation:

Let x be the amount of detergent in ounce of 15% bleach and let y be the amount of detergent in ounce of 40% bleach.

Since 48 ounces of detergent is made, hence:

x + y = 48 (1)

Also, 15% bleach detergent and 40% bleach detergent is mixed to make 48 ounces of a detergent that is 23% bleach, therefore:

0.15x + 0.4y = 0.23(48 ounce)

0.15x + 0.4y = 11.04 (2)

To find x and y, we solve equation 1 and equation 2 simultaneously by multiplying equation 1 by 0.15 and subtracting the result from equation 2:

0.25y = 3.84

y = 15.36 ounces

Put y = 15.36 in equation 1 to get:

x + 15.36 = 48

x = 48 - 15.36

x = 32.64 ounces

Therefore 32.64 ounces of a detergent that is 15% bleach was mixed with 15.36 ounces of a detergent that is 40% bleach to get 48 ounces of a detergent that is 23% bleach.

A flock of pigeons flew to a tall tree. Some of them perched on the branches, others landed under the tree.

Answer:

There are 7 on the tree, and 5 below

Step-by-step explanation:

If one left the bottom, there would be 8 on top and 4 below. Therefore, twice as many. If one left the top it would be both 6 and 6.

Answer:

7 pigeons sitting on the branches, 5 pigeons under the tree

Step-by-step explanation:

Number of pigeons on the branches = bNumber of pigeons under the tree = t

We got equations below:

b + 1 = 2(t - 1) ⇒ b = 2t - 3b - 1 = t + 1 ⇒ b = t + 2

Eliminate b and solve for t:

2t - 3 = t + 22t - t = 2 + 3t = 5

Then find b:

b = t + 2 = 5 + 2 = 7

Write two numbers that multiply to the value on top and add to the value on bottom.
