Evaluate the expression 3r^2 if r = 1/6.

Answers

Answer 1

Answer:

0.08333

Step-by-step explanation:

3(1/6)^2

1/6=0.1666

1/6^2=0.02777

3*0.02777=0.08333

Answer 2

Answer:

1/12

Step-by-step explanation:

This is the answer because:

1) 1/6^2 = 1/36

2) 1/36 x 3 = 3/36 = 1/12 ↔ 3 ÷ 3 = 1 & 36 ÷ 3 = 12 = 1/12

Therefore, the answer is 1/12.

Ratio: 9:2

We should divide 468 by 9, use the number we find, and then multiply it by 2.

468 / 9 = 52

Answers

Answer:

x = -1

Step-by-step explanation:

The axis of symmetry of the graph [tex]y=(x-3)^2[/tex] is  x=3 but,

If shift the graph 4 units to the left it would mean the new value of x would be -1 as shown here:

[tex]x=3-4\\x=-1[/tex]

-4 because it shifted 4 units to the left so the axis of symmetry of the transformed graph would be x = -1 and since it shifted 2 units down the y-coordinate of the turning point would be -2 so the turning point of the original graph is (3 , 0) and the turning point of the transformed graph is

Step-by-step explanation:

To obtain 75% of 56 ;

Mathematically ;

Given g(x) = 2x – 1, solve for x when g(x) = 3.

Answers

Answer:

x = 2

Step-by-step explanation:

g(x) = 2x - 1

g(x) = 3

2x - 1 = 3

Add 1 to both sides;

2x = 4

Divide both sides by 2;

x = 2

Answer: x = 2

Explanation:

Set g(x) = 3

3 = 2x - 1
Add 1 to both sides
4 = 2x
Divide by 2 on both sides
x = 2

Ricardo has $25 to spend on school supplies. He spends 56% of the money on a backpack and the rest on a large binder. How much money does he spend on the backpack? How much does he spend on the binder

Answers

Answer:

Ricardo spends $14 on the backpack and $11 o the binder.

Step-by-step explanation:

First, you have to calculate 56% of the amount Ricardo has to spend on school supplies to find the money he spends on the backpack:

$25*56%=$14

Now, you have to subtract 56% from 100% to find the percentage that he spent on a large binder:

100%-56%=44%

Finally, you have to calculate the 44% of the amount Ricardo has to spend on school supplies to find the money he spends on a large binder:

$25*44%=11

According to this, the answer is that Ricardo spends $14 on the backpack and $11 o the binder.

Tyrese wants to buy 15 packs of baseball cards. They cost $ 5.00 per pack. There is a 25 % discount before tax if 10 or more packs are purchased. Sales tax is 7 % . Tyrese gives the cashier $ 100 to pay for his baseball cards. How much change will he receive in return?

Answers

Answer:

Tyrese will receive $39.81 in return.

Step-by-step explanation:

First, you have to multiply the 15 packs for the cost per pack:

15*$5=$75

As there is a 25% discount before tax if 10 or more packs are purchased, you have to calculate 25% of the total cost for the 15 packs and subtract that amount from the cost:

$75*25%=$18.75

$75-$18.75=$56.25

Then, you have to calculate 7% of the amount with the discount and add that to the cost:

$56.25*7%=$3.93

$56.25+$3.94=$60.19

Now, you can subtract $60.19 from $100 to find the change that Tyrese will receive in return:

$100-$60.19= $39.81

According to this, the answer is that Tyrese will receive $39.81 in return.
