2 answers:

8 0

To find the answer you do 4 divided by 5 which = 0.8
Then, you move the decimal over two spaces to the right or multiply it by 100 and there's your answer. So, doing this you get:
80%

Next look at 5 going into 40, which = 8. This gives you the answer 0.8 this is the answer of 8tenths. To form a percent<span> multiply the decimal by 100 (or move decimal two places to the right) because % is always out of 100. Place a % sign at the end and rid the decimal. soo your answer is 80%

Let f(x)=x2−16x+71 .what is the vertex form of f(x)?what is the minimum value of f(x)? enter your answers in the boxes.

adell [148]

Your vertex is (8,7)

First find the x intercept
-2/2a

X = 16/2
X = 8

Substitute the value x and solve for y
Youd get 7

Hence
(8,7)

A man has a collection of dimes and nickels with a total value of $1.70. if he has 8 more dimes than nickels how many of each co

Oxana [17]

Answer:

Step-by-step explanation:

We first have to write an expression for each of the types of coins in terms of one of them. If he has 8 more dimes than nickels, let's call nickels "x". That means that dimes is "x + 8". The value of a nickel is .05, so the expression relating the number of nickels to the worth of the nickel is .05x. The value of a dime is .10, so the expression relating the number of dimes to the worth of the dime is .10(x + 8). The total value of these coins is 1.70:

.05x + .10(x + 8) = 1.70 and

.05x + .10x + .8 = 1.70 and

.15x = .9 so

x = 6

That means we have 6 nickels and 14 dimes.

Give the values of Xmin, Xmax, Ymin, and Ymax for the screen, given the values for Xscl and Yscl.

joja [24]

Answer: Option C.

Step-by-step explanation:

Xmin, Xmax, Ymin, and Ymax represent the minimum/maximum values that X and Y can take.

We know that the scale in Y and X is 10.

This means that each mark in each axis represents 10 units.

Now, let's go to the vertical axis (y-axis)

Counting from the (0, 0) we can count:

4 marks up

4 marks down.

So if each mark represents 10 units, 4 marks are 40 units.

Then the range for Y is {-40, 40}

Now for the horizontal axis.

We can count 3 marks on each side, and with the same reasoning as before, we can find that the range for X is: {-30, 30}

Then we have that:

Xmin = -30

Xmax = 30

Ymin = -40

Ymax = 40

Now, as a point is defined as (X, Y)

This region can be written as:

{Xmin, Xmax} by {Ymin, Ymax}

or, replacing the values:

{-30, 30} by {-40, 40)

So the correct option is C.
