mary purchased 3 1/2 pounds of bananas. If the loaf of banana bread requires 3/4 pounds of bananas, how many loaves of banana br
nikklg [1K]
For this one a simple way that you can think of it is that 1 pound of banana is equivalent to 100, 3/4 pounds of banana is 75, 1/2 pounds of banana is 50, etc. 

3 1/2 pounds of banana = 350 

3/4 pounds of banana = 75 

If i want to find out how many loafs of banana bread I can make if ONE loaf requires 3/4 pounds of banana, and i have 3 1/2 pounds of banana then I divide:

350 / 75 = 4.66 

So, with 3 1/2 pounds of bananas you can successfully create 4 loafs of banana bread. the remaining .66 is not enough banana to make another loaf.

Kara used the linear model y=45,000+ 0.05x to predict her total salary from achieving total sales of x.
hoa [83]

Answer:

45,000 is the starting salary with zero sales

.05 is the amount multiplied by the number of sales that is added to her salary

For each sale we add .05 to her salary

Step-by-step explanation:

y = 45,000 +.05x

Rewriting as

y = .05x +45,000

This is in slope intercept form ( y=mx+b) where m is the slope and b is the y intercept

.05 is the slope and 45,000 is the y intercept

45,000 is the starting salary with zero sales

.05 is the amount multiplied by the number of sales that is added to her salary

For each sale we add .05 to her salary

The winner of a 200 mile race drove his car to victory at a rate of 140.2159 mph. What was his time​ (to the nearest thousandth
Keith_Richards [23]

Answer: 1.43 h

Step-by-step explanation:

Velocity is V is defined as the change in position (displacement) d of an object in a specific time t:

V=\frac{d}{t}

Where:

V=140.2159 mi/h is the car's velocity

d=200 mi is the distance the winner car traveled

t is the time

Isolating t:

t=\frac{d}{V}

Solving with the given information:

t=\frac{200 mi}{140.2159 mi/h}

t=1.426 h \approx 1.43 h This is the winner's time
