A. $40
B. $135
C. $140
D. $145

Ben Had $100 In His Savings Account. He Adds $5.00 A Week To His Savings As Shown In The Graph Below.

Answers

Answer 1

Answer:

Option (C)

Step-by-step explanation:

Let the relation between amount of money (m) and Time (t) is represented by the equation,

m = ct + b

Where c = Investment per week

b = Ben already had the amount before investment

From the question,

c = $5 per week

b = $100

Therefore, equation will be,

m = 5t + 100

If duration of the investment 't' = 8 weeks

Amount in the account after 8 weeks,

m = 5(8) + 100

m = $140

Option (C) is the correct option.

The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the
hypotenuse by the formula a? + b2 = -2
If a is a rational number and b is a rational number, why could c be an irrational number?

Answers

Answer:

For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.

Step-by-step explanation:

We all know, the Pythagorean theorem can be stated as follows:

The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.

i.e.

[tex]a^2+b^2=c^2[/tex]

Where, [tex]c[/tex] is the hypotenuse and [tex]a, b[/tex] are the two other legs of the right angled triangle.

Given that:

[tex]a[/tex] and [tex]b[/tex] are rational numbers.

To find:

Situation for which [tex]c[/tex] is irrational.

Square of a rational number is always rational.

So, [tex]a^{2} , b^{2}[/tex] both will be rational.

And sum of squares of two rational numbers will also be rational.

Therefore, [tex]a^2+b^2[/tex] will also be rational.

and

[tex]c = \sqrt{a^2+b^2}[/tex]

For the value of [tex]c[/tex] can be irrational, sum of squares of other two legs might be imperfect square number.

If Triangle ABC~trIangle DEC, find the value of x and y."

Answers

Answer:

The right answer would be (D) x = 1.

Step-by-step explanation:

So since triangles ABC and DEC are congruent to each other, your gonna try to find the value of x. So from the figure we know that AB = 4x - 1, BC = 4, AC = 5,  DE = x+2, CE = 4 and EC = 5. And since ΔABC ≅ ΔDEC the corresponding sides would be equal. And after, we will have :

AB = DE

4x - 1 = x + 2

4x - x =2 + 1

3x = 3

x = 1

So, as it shows, the value of x is one. So (D) x = 1 is the right answer. Hope this helped! :)

Expression A Expression B Expression C (−5)(−0.4)(1.8) (-45)(-19)(-112) −1(5+17) Expression D Expression E Expression F (−5)(−0.4)(1.8)(−3.25) (-49)(-34)(-12)(-12) −1(3.5−7) How many expressions will have a product that is positive?

Answers

Answer:

Expressions A, E, and F

Step-by-step explanation:

In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.

Thus,

A. (−5)(−0.4)(1.8) = (2.0)(1.8)

                           = 3.6

B. (-45)(-19)(-112) = (855)(-112)

                           = -95760

C. −1(5+17) = -1(22)

                 = -22

D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)

                                      = -11.7

E. (-49)(-34)(-12)(-12) = (1666)(144)

                                = 239904

F. −1(3.5−7) = -1(-3.5)

                  = 3.5

Thus expressions A, E and F have positive products.

Seven less than 4 times the square of a number is 18. Find the two numbers.

Answers

The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

Let the unknown number be "x"

The square of an unknown number is expressed as x²

4 times the square of a number  is 4x²

Seven less than 4 times the square of a number is 4x² - 7

If the resulting expression is 18, this will be expressed as 4x² - 7 = 18

Solving the resulting expression

[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]

Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

A bag contains 10 red, 3 blue, and 2 yellow marbles. If 3 marbles are selected one at a time with replacement, find the probability that all three are different colors

Answers

Answer:

4/225

Step-by-step explanation:

To get 3 marbles that all three are different colors, we need to get a red, blue, and yellow marble (not necessarily in that order)

So we get the probability of getting each with replacement (meaning they are all out of 15) and multiply them.

The probability of getting a red is:

10/15 = 2/3

The probability of getting a blue is:

3/15 = 1/5

The probability of getting a yellow is:

2/15

So to get all 3 different colors:

2/3 * 1/5 * 2/15 = 4/225

it's pretty easy to add considering the denominators are the same number. technically in this problem it's 3+1 and then add the denominator which is 7. this makes the answer 4/7

Answer:

4/7

The word together symbolizes that we are adding.

We add the numerators but keep the denominator the same since it is already the same.

1+3 is 4, so that is our new numerator.

y is directly proportional to x. When y = 24, ,x=8. Work out the value of y when x=2​

Answers

Answer:

When x = 2, y = 6

Step-by-step explanation:

Constant of Proportionality:  y = kx

       k = 3

     y = kx       ===>        y = 3x

When x = 2:
