Mark had a ratio of 4 misses to 3 makes when he shot free throws in the last game. If he maintains this ratio, how many free throws will he make if he shoots 154 total free throws?

Answers

Answer:

88 misses / 66 makes

Step-by-step explanation:

Mark's ratio consists of 4+3=7 total shots.

154 shots would be 22*7 since the ratio would remain proportional

Therefore, (22*4)/(22*3)=88/66 will be the ratio of free-throw misses to makes. This means Mark will make 88 misses and 66 makes if he does 154 total free throws.

Simplify the expression. Write your answer as a power.
(-4).(-4)
The simplified expression is

Answers

Answer:

(-4).(-4) = 4^2

Step-by-step explanation:

First, some rules that we need to remember:

if A is a positive number, then:

-A = (-1)*A

Also:

A*A = A^2

We also should remember that we can multiplicate in any order we want, this is:

A*B*C = (A*B)*C = A*(B*C)

And we also can change the order of the numbers:

A*B = B*A

And finally, we need to remember the sign rules for multiplication.

(+)*(+) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(-)*(-) = (+)

Ok, now let's look at our expression.

(-4)*(-4)

First, we can rewrite this as:

( (-1)*4)*((-1)*4)

And we can rearrange the numbers to:

(-1)*(-1)*4*4

Now let's multiplicate the first two ones, because of the sign rule, we know that the outcome will be positive, and 1 times 1 is equal to 1,

(-1)*(-1) = 1

Then:

(-1)*(-1)*4*4 = 1*4*4 = 4*4

And we know that when a number is multiplied by itself we can rewrite it as:

4*4 = 4^2

Then:

(-4).(-4) = 4^2

The simplified expression is 4^2

Fannie is making a rectangular blanket. The length of the blanket is 10 inches greater than its width, w, in inches. Write the function, f(w), that describes the area, in square inches, of Fannie's blanket as a function of the width, w

Answers

Answer:

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

Step-by-step explanation:

Let the width of the rectangular blanket be given by w and the length be given by l. According to the given condition length = 10+ width

Area of the rectangular blanket= length * width

A= l*w    ( as l= w+10)

A = (w+10) w

A= w²+ 10w

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

What is the area of a rectangle?

The area of the rectangle is the product of the length and width of a rectangle.

Area of rectangle = L × W

Let the width of the rectangular blanket be given as w and the length be given by l.

The length is given as 10 inches greater than its width

length = 10+ width

Area of the rectangular blanket= length × width

A= l × w    

also, A = (w+10) w

A= w²+ 10w

Therefore, the function f(w) = w²+ 10w gives the area of the rectangular blanket.

more slope pls helpppppp

Answers

Answer:  C) 2

Explanation:

Recall that the general point-slope form is [tex]y - y_1 = m(x - x_1)[/tex] where m is the slope and [tex](x_1, y_1)[/tex] is the point the line goes through. We see that the 2 and the m match up, so m = 2 is the slope.

Side note: We can rewrite that given equation into y - (-5) = 2(x - (-1)) to see that the line goes through the point (-1, -5)

Answer:

C: 2

Step-by-step explanation:

y + 5 = 2x + 2 (distribute 2)

y = 2x -3 (subtract 5 from both sides)
