===================================================

Explanation:

We have a white triangle shown as the empty space between the green squares.

This right triangle has the following sides:

a = unknown horizontal legb = 6 = vertical legc = 8 = hypotenuse

Use the Pythagorean Theorem to solve for 'a'

a^2 + b^2 = c^2

a^2 + 6^2 = 8^2

a^2 + 36 = 64

a^2 = 64 - 36 ..... subtract 36 from both sides

a^2 = 28

a = sqrt(28) .... apply the square root to both sides

Optionally we can simplify like so

a = sqrt(28)

a = sqrt(4*7)

a = sqrt(4)*sqrt(7)

a = 2*sqrt(7)

But this would not fit the answer format your teacher has provided. So we'll stick to sqrt(28) as the final answer.

At the beginning of the year, John had $40 in savings and saved an additional
$13 each week thereafter. Isaac started the year with $80 and saved $9 every
week. Let J represent the amount of money John has saved t weeks after the
beginning of the year and let I represent the amount of money Isaac has
saved t weeks after the beginning of the year. Write an equation for each
situation, in terms of t, and determine the number of weeks after the
beginning of the year until John and Isaac have the same amount of money
saved.

Answers

Answer:

J= 40+13t

I= 80+9t

they are equal at 10 weeks

Step-by-step explanation:

So we can start this by writing our equations

J= 40+13t

I=80+9t

To figure out when they're equal set the two equations equal to each other and solve for t

40+13t=80+9t

subtract 40 and 9t from both sides to get

40=4t

divide by 4 and get

t=10

Write an algebraic expression for "8 less than the product of 3 and j"

Answers

Answer: 3(j)-8

Step-by-step explanation: well first the product means multiplication, so u multiply 3 and j. and the second part is 8 less than that, so 8 is the last part so u do 3 times j minus 8. i graduated from high school last year so i know what im doin

The algebraic equation will be "3j - 8".

According to the question,

Let,

The first number be "3".The second number be "j".The third number be "8".

Now,

The product of "3" and "j" will be "3j" and the third number i.e., "8" less than the product.

Then the equation will be:

[tex]3j-8[/tex]

Thus the above response is appropriate.

The cost of items at store A is approximately Normally distributed with a mean of $4.15 and a standard deviation of $2.68. The cost of items at store B is approximately Normally distributed with a mean of $5.35 and a standard deviation of $1.75. Assume that A (the cost of a randomly selected item from store A) and B (the cost of a randomly selected item from store B) are independent random variables. Let D = A-B. Which of the following correctly interprets the mean of D?
o $1.20. One randomly chosen item will cost $1.20 less at store A than at store B.

0 -$1.20. On average, a person can expect to spend $1.20 less at store A than at store B for many randomly chosen items.

O $1.20. One randomly chosen item will cost $1.20 more at store A than at store B.

O $1.20. On average, a person can expect to spend $1.20 more at store A than at store B for many randomly chosen items.

O $9.50. On average, a person can expect to spend a total of $9.50 at stores A and B. ​

Step-by-step explanation:

So like the last one we just have to find the distances between x on point a and x on point x and the distances between y on point a and y on point b. 4+2=6 and 3+3=6 and since we are trying to find the point that is 1/6 of the distance from a we do 6/6 and 6/6 which is 1 and 1. Then we subtract 1 from the x and y values of A. So the coordinates 1/6 of the way is (3,2)

Evaluate the function expression
5•f(1)+5•g(9)=​

Answers

Step-by-step explanation:

By getting our values from the graph,

When x = 1, the blue line has y-value -5.

When x = 9, the dotted line has y-value -6.

Hence,

f(1) + 5 * g(9) = (-5) + 5(-6) = -35.

Answer:

From the above graph,

→When x=1, y=f(1)=-5

→When x=9, y=g(x)=-6

• 5×f(1)+5×g(9)

=5{f(1)+g(9)}

=5{(-5)+(-6)}

=5(-11)

=-55

-55 is the right answer.

they are both on the 2 of the y-axis, so now all you have to do is subrtact the x-axis coordinate of R by the x-axis coordinate of T. That would be (-6)-5 = -11. YOUR ANSWER IS NOT -11.
