A fruit basket contains only apples and bananas. If there are 8 apples and 13 bananas, what is the ratio of bananas to fruit? Select all that apply. 13:8

Answers

Answer:

The ratio of bananas to total fruit is 13:21

Step-by-step explanation:

Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.

Answer: 13:21

13:21 is the correct answer I hope it helps

Find the x-intercept of the graph of the equation =−.+y equals negative , 2.65 , x plus 25.
What does the x-intercept mean in terms of the situation?

Answers

Answer:

Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

math problem: Amanda worked 4.5 hours on Tuesday and 5.2 on Thursday. Her pay rate is $10.50 per hour. How much will Amanda get paid for the two days?

Answers

Answer:

$101.85

Step-by-step explanation:

Think of the two days as separate equations. They are added together to get a sum of the pay she will receive after the two days.

Equation

(4.5*10.5) + (5.2*10.5) = x (This just represents the unknown value)

Solve Through

(47.25) + (54.60) = x

47.25 + 54.60 = x

101.85 = x

Amanda will get paid $101.85 For her 2 days of work.

A bottlenose dolphin is 10 feet below sea level. Then it begins to dive at a rate of 9 feet per second. What is the equation of the line that represents its elevation, y, after x seconds?
A.
y = 9x − 10
B.
y = -9x − 10
C.
y = 9x + 10
D.
y = -9x + 10

Answers

B is the correct answer

Answer:

B. y=-9x-10

Step-by-step explanation:

The dolphin is starting 10 feet below sea level so the y-intercept (or b in slope-intercept form) would be negative 10. Diving means going down, or a negative slope, so the slope would be -9. When you plug those numbers into y=mx+b, you would get y=-9x-10.

$1,381

Because 375×4= 1,500

Susan has $1381.

Find the equation of a line whose slope is one-half and y-intercept is 2.

Answers

Answer:

[tex]y=\frac{1}{2} x+2[/tex]

Step-by-step explanation:

To find this you can use slope-intercept form which is y=mx+b where m=slope and b=y-intercept. You just have to plug both numbers in, giving you [tex]y=\frac{1}{2} x+2[/tex].

The equation of a line is y=mx+c
Where m is the gradient and c is the y intercept
If you substitute m with 0.5 and c with 2 the answer will be y=0.5x+2

Answers

i’m pretty sure it’s a and c
It has to be A and C

Can someone please give me an answer.

Answers

It is not A. It’s B!
The reason it’s B is because when you look at the table, the y- intercept (or where it’s at when it’s at 0) is -75.
So you know it’s
Y= (something) -75
When you look at the rest of the table you can see that for every five it’s going up on the left side, it’s going up 25 on the right side.
If you divide 25 by 5 to figure out how much it is going up per 1 time instead of 5, you will get 5. You have to add X to that because that is the slope or how much you are going up by.
That means your equation is...
y=5x-75, or B!
Hopefully that helps you!

The answer is y=5x-75 or B
