Answer:

(7x)^{\frac{2}{3}}=\sqrt[3]{49x^{2} }

Step-by-step explanation:

We have been given the expression;

7 times x to the two thirds power which can be written mathematically as;

(7x)^{\frac{2}{3}}

To express the above expression as a radical, we need to recall that;

a^{\frac{b}{n}}=\sqrt[n]{a^{b}}

Therefore;

(7x)^{\frac{2}{3}}=\sqrt[3]{(7x)^{2} }\\\\=\sqrt[3]{49x^{2} }

3. Jen’s parents buy a tablet for her to use in school. Of the $1500 cost, her parents expect her to pay back $1000 one year lat
NNADVOKAT [17]

Answer:

<h3>33.3%</h3>

Step-by-step explanation:

Using the formula for calculating simple interest as shown;

Simple Interest = Principal * Rate *Time/100

Principal = Cost of tablet = $1500

Interest after one year  =  $1500-$1000 = $500

Time = 1year

Substituting this values into the formula;

500 = 1500*rate*1/100\\Cross\ multiplying\\50,000 = 1500 * rate\\Rate = 50,000/1500\\Rate = 33.3%

The interest rate that her parents assumed is 33.3%

A probability experiment will consist of selecting one of two stacks of cards, and then choosing a card at random from the stack
postnew [5]

Answer:

The probability that the red card came from the first stack is:

40%

Step-by-step explanation:

a) Data and Calculations:

Stack         Red      Blue   Total

First            6           5         11

Second      9            0         9

Total         15            5       20

The probability of selecting from the first stack = 50% since equal opportunity is given to the two sacks.

The probability of red card from the first stack = 6/15 = 0.4 = 40%.

b) The probability that the red card came from the first stack is given by the number of red cards in the first stack divided by the number or red cards in the two stacks.  This is equal to 6/15 = 0.4 or 40%.

Answer:

160 m²

384 m²

Step-by-step explanation:

The area of a trapezium is given by :

A = 1/2(a + b)h

h = height ; a and b = lengths

From the diagram :

A = 1/2(12 + 20)10

A = 1/2(32)10

A = 16 * 10

A = 160 m²

2.)

Area of parallelogram = base * height

Base = 24 ; h = 16

A = 24 * 16

A = 384 m²

Answer:   3/2

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

Explanation:

Pick any two points on the red line. I'll pick (0,1) and (2,4)

Those coordinates will be plugged into the slope formula below

m = (y2 - y1)/(x2 - x1)

m = (4 - 1)/(2 - 0)

m = 3/2

This means we go up 3 and over to the right 2 when traveling along this red line.
