(1)    Snow fall in last week = 3 \frac{1}{2} inches

Snow fall in today= 5 \frac{3}{4} inches

Let us first change mixed fraction to improper fraction.

\begin{aligned}&3 \frac{1}{2}=\frac{7}{2}\\&5 \frac{3}{4}=\frac{23}{4}\end{aligned}

Now, make the denominators same.

3 \frac{1}{2}=\frac{7}{2}=\frac{7 \times 2}{2 \times 2}=\frac{14}{4} ,       5 \frac{3}{4}=\frac{23}{4}

Now, find the difference between 14/4 and 23/4.

\frac{23}{4}-\frac{14}{4}=\frac{9}{4}=2 \frac{1}{4}

So, compared to last week 2 \frac{1}{4} more inches of snow fell today.

(2)    Given three times a number, minus nine, equals six times six, divided by four.

Let a number be X.

3X – 9 = 6 × 6/4

(3)  To solve the equation:

3X – 9 = 6 × 6/4

3X – 9 = 36/4

3X – 9 = 9

3X = 18

X = 6

Kelly is having a party. She wants to make punch. The recipe for punch uses 3 pints of pineapple juice, 5 cups of orange juice,
lorasvet [3.4K]

Answer:

Kelly is wrong and the recipe will make 19 cups of punch.

Step-by-step explanation:

It says:

The amount of ingredients in the recipe of punch after converting the units to 'cups' are given by,

Pineapple juice = 3 pints = 6 cups (1 pint ≈ 2 cups)

Orange juice = 5 cups

Lemonade = 1/4 gallon = 4 cups (1 gallon = 16 cups)

Apricot nectar = 1 quart = 4 cups(1 quart = 4 cups)

Then, the total cups of punch = 6 + 5 + 4 + 4 = 19 cups.

Thus, Kelly is wrong and the recipe will make 19 cups of punch.

Crazy boy [7]

Answer:

The probability that Justin will practice soccer this evening is 16%.

Step-by-step explanation:

The probability that John will practice soccer is given by the product of the probability that it won't snow and the probability that he'll practice soccer. This is shown below:

practice soccer = (1 - 0.6)*0.4

practice soccer = 0.4*0.4

practice soccer = 0.16

The probability that Justin will practice soccer this evening is 16%,

type the correct answer in each box. use numerals instead of words. if x > 0, what values of c and d make the equations true?
Gemiola [76]

The values of c and d which makes the given equations true are 7 and 5 respectively.

<h3>What is an exponent?</h3>

An exponent can be defined as a mathematical operation that is used to raise a quantity to the power of another and it is generally written as bⁿ.

<h3>How to determine the value of c and d?</h3>

From equation A, we have:

\sqrt{448x^c} = 8x^3\sqrt{7x} \\\\\sqrt{448x^c} = \sqrt{(8x^3)^2 \times 7x } \\\\\sqrt{448x^c} = \sqrt{64x^6 \times 7x } \\\\\sqrt{448x^c} = \sqrt{(64 \times 7)x^{6+1} }\\\\\sqrt{448x^c} = \sqrt{448x^{7} }

c = 7.

From equation B, we have:

\sqrt[3]{576x^d} = 4x\sqrt[3]{9x^2} \\\\\sqrt[3]{576x^d} = \sqrt[3]{9x^2 \times (4x)^3}\\\\\sqrt[3]{576x^d} = \sqrt[3]{9x^2 \times 64x^3}\\\\\sqrt[3]{576x^d} = \sqrt[3]{9 \times 64x^{3+2}}\\\\\sqrt[3]{576x^d} = \sqrt[3]{576x^{5}}

d = 5.

A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636

as a fraction it would be 36/99, divide both numbers by 9 to get 4/11

B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666
 as a fraction that would be 33/90 , divide both by 3 to get 11/30

C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25
