Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

6 × 3 = 18

9 × 3 = 27

18 + 27 = 45

Answer 2

Answer: Answer 45

9+ 9 = 18 + 9 = 27
6 + 6 = 12 + 6 = 18
27 + 18 = 45

What times what equals 90

Answers

The question is asking to state the two number that when multiplied, the product would be 90, base on my calculation, I would say that the answer would be 45*2, 90*1, 30*3, and 18^5. I hope you are satisfied with my answer and feel free to ask for more if you have questions

The pairs of numbers that multiply to 90 are (1, 90), (2, 45), (3, 30), (5, 18), (6, 15), and (9, 10).

To find two numbers that multiply to equal 90, we can look for pairs of factors of 90.

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.

To determine the pairs of factors that multiply to 90, we can list the pairs:

1 × 90 = 90

2× 45 = 90

3 × 30 = 90

5 × 18 = 90

6 × 15 = 90

9 × 10 = 90

Therefore, the pairs of numbers that multiply to 90 are: (1, 90), (2, 45), (3, 30), (5, 18), (6, 15), and (9, 10).

What is the slope of a line that passes through the points (2, 0) and (5, 0)? Explain.incorrect answer: 0; The change in $x$ is 0 because the x-values do not change. So, the slope is 0.

a) 0; The change in y is 0 because the y-values do not change. So, the slope is 0.

b) undefined; The change in x is 0 because the x-values do not change. So, the slope is undefined.

c) undefined; The change in y is 0 because the y-values do not change. So, the slope is undefined.

d) 2/5; To find slope, divide the x-value of the first point by the x-value of the second point. So, the slope is 2/5.

e) 5/2; To find slope, divide the x-value of the second point by the x-value of the first point. So, the slope is 5/2.

Answers

it is 0, the change in y is 0 , the slope is zero!

ABC is an isosceles triangle.
AB = BC = 8
Therefore Angle B = 30 degrees
So, Angle A = 180 -30 -30
Angle A = equals 120 degrees
answer is B

The answer is B, 120.

The equation d= -6t + 10 represents the distance d, in miles, Ralph walks from the library to his house in t hours. His sister, Joan, leaves the library right after Ralph. She rides her bicycle from the library to their house at a constant rate. The equation d = 14t represents Joan's bicycle ride where d, is the distance, in miles, and t is the time, in hours.After how many miles will Joan meet Ralph walking to their house?

Step-by-step explanation:

Step 1: Define

Identify given.

[Ralph's Walking Distance Function]: d = -6t + 10

[Joan's Bicycle Distance Function]: d = 14t

Step 2: Find Meeting Point

To find where Joan and Ralph will meet, we need to find where they intersect. Therefore, we need to find the time which they both meet up at. To do this, we can use the process of substitution to find our value of t:

[Equation 1] Substitute in d:
$\displaystyle\begin{aligned}d = -6t + 10 & \rightarrow 14t = -6t + 10\end{aligned}$

From here, we can simply use techniques listed under "Algebra I" to solve for t:

$\displaystyle\begin{aligned}14t & = -6t + 10 \n20t & = 10 \nt & = \boxed{ (1)/(2) } \n\end{aligned}$

∴ both Joan and Ralph will meet up in half an hour, or 0.5 hours.

Step 3: Find Mileage

To find how many miles they will meet up at, we substitute the number of hours elapsed (found in Step 2) and substitute it into any of the equations given:

$\displaystyle\begin{aligned}d & = 14t \n& = 14 \bigg( (1)/(2) \bigg) \n& = \boxed{7} \n\end{aligned}$
