Answer:

The area of trapezoid is 39.6cm²

Step-by-step explanation:

Given that the formula of area of trapezoid is A = 1/2×(a+b)×h where a and b is the length and h is the height. So you have to substitute the values into the formula :

[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]

[tex]let \: a \: = 8.9 \\ let \: b \: = 5.5 \\ let \: h \: = 5.5[/tex]

[tex]area = \frac{1}{2} \times (8.9 + 5.5) \times 5.5[/tex]

[tex]area = \frac{1}{2} \times 14.4 \times 5.5[/tex]

[tex]area = \frac{1}{2} \times 79.2[/tex]

[tex]area = 39.6 {cm}^{2} [/tex]

 Answer: The area is 39.6

Step-by-step explanation:

First multiply 5.5×5.5= 30.25

Then subtract 8.9 - 5.5=3.4

Then multiply 5.5 x 3.4=18.7

Divide 18.7/2=9.35

Add 30.25 + 9.35 =39.6

b x h ÷2

Answer:

The remaining area in the form of a polynomial function [tex]A(x)= 140-4x^2[/tex]where  0 < x < 3.

Step-by-step explanation:

Breadth of rectangular piece of cardboard = 7 inches

Length of rectangular piece of cardboard = 20 inches

Area of cardboard = [tex]Length \times Breadth[/tex]

Area of cardboard = [tex]20 \times 7[/tex]

Area of cardboard =[tex]140 in^2[/tex]

Squares of length x inches on a side cut from each corner.

Length of square = x

Area of 1 square = [tex]Side^2 = x^2[/tex]

Area of 4 squares = [tex]4x^2[/tex]

Area of remaining portion [tex]A(x)= 140-4x^2[/tex]

So, the remaining area in the form of a polynomial function [tex]A(x)= 140-4x^2[/tex]where  0 < x < 3.

Answer:

$2

Step-by-step explanation:

$2 because it's in between.

The total playing value will be $0.

What is probability?

Probability shows the possibility of any event to occur. The maximum value of probability can be 1 and shows the event will happen, and minimum can be 0, shows that event will not occur.

Given that,

Cost of playing the game= $2

There are total 52 playing cards,

Red cards=26

So, the probability to come red on card = 1/2.

Black cards=26

So, the probability to come black on card=1/2

If investor invests $2,

For red card, win $3,

The profit is $1

For black card, win $1,

The loss is $1

Total invest = $4

Total earning=$4

playing value = $4-$4=0.

So the total playing value will be $0.

The median of [tex]\triangle ABC[/tex] are lines CD, AE and BF. These lines meet at point Q, makes Q the centroid. The length of QE is 9 units.

The centroid of a triangle divides the median of a triangle using the following ratio;

[tex]m:n = 2:1[/tex]

This means that:

[tex]BQ:QF=2:1[/tex]

[tex]AQ:QE=2:1[/tex]

[tex]DQ:QC=2:1[/tex]

To calculate QE, we make use of:

[tex]AQ:QE=2:1[/tex]

From the triangle;

[tex]AQ = 18[/tex]

So, we have:

[tex]18:QE=2:1[/tex]

Express as a fraction

[tex]\frac{18}{QE}=\frac{2}{1}[/tex]

Cross multiply

[tex]2 \times QE = 18 \times 1[/tex]

[tex]2 \times QE = 18[/tex]

Divide both sides by 2

[tex]QE = 9[/tex]

Hence, the length of QE is 9 units.

Answer:

1/4

Step-by-step explanation:

In a spinner which has 4 equal-sized sections., the probability of pointer must land on a purple section to win the game is 1/4.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

A spinner has 4 equal-sized sections. To win the game, the pointer must land on a purple section.  Thus, the number of favorable outcomes is,

[tex]P(\text {purple}) =1[/tex]

Total number of possible outcomes is 4 as there is 4 equal-sized sections. Thus, the probability of the pointer must land on a purple section is,

[tex]P=\dfrac{1}{4}[/tex]

Thus, in a spinner which has 4 equal-sized sections., the probability of pointer must land on a purple section to win the game is 1/4.

For the base value of 4, if the exponent is 2; the value will be 16.

For the base value of 4, if the exponent is -2; then value will be 1/16.

A base number and an exponent are typically used to denote a power.

The total number of digits required to express numbers in a number system is known as the base in mathematics. What number is being multiplied is revealed by the base number.

The exponent, a little number printed above and to the right of the base number, provides the multiplicative power of the base number.

The base number is given as 4.

The exponent is given as 2.

So, the number becomes,

=> [tex]4^{2} =4[/tex]×[tex]4[/tex]

= 16

Thus, the base 4 with exponent 2 becomes 16.

The base number is given as 4.

The exponent is given as -2.

So, the number becomes,

=> [tex]4^{-2} =\frac{1}{4^{2} }[/tex]

= [tex]\frac{1}{16}[/tex]

Thus, the base 4 with exponent -2 becomes 1/16.
