What is the area of the composite figure below?

A) 84 square inches
B) 90 square inches
C) 98 square inches
D) 104 square inches

Answer:

The dimensions of the vegetable patch is 8 m by 7 m.

Step-by-step explanation:

Area of a vegetable patch is 56 square meters and the perimeter is 30 m.

If l is length and b is breadth, then area and perimeter of a rectangle is given by :

[tex]A=l\times b[/tex]

[tex]P=2(l+b)[/tex]

Substituting the values in the above formulas as :

[tex]l\times b=56\ ....(1)[/tex]

and

[tex]2(l+b)=30\\\\l+b=15\ .....(2)[/tex]

We need to solve equation (1) and (2) to find the values of l and b such that :

Equation (2), l = 15 - b

Equation (1) becomes,

[tex](15-b)b=56\\\\b=7\ m, 8\ m[/tex]

If b = 7 m, so, l = 8 m

If b = 8 m, l = 7 m

So, the dimensions of the vegetable patch is 8 m by 7 m.

As the radius of the circle is 5

You need to square this value for it to fit the equation

5^2 = 25

Thus, your answer would be option B

[tex]\sqrt{18}[/tex] = [tex]\sqrt{3*6}[/tex] = [tex]\sqrt{3*3*2}[/tex] = [tex]\sqrt{3^{2}*2 }[/tex] = [tex]3\sqrt{2}[/tex]

Answer:

The volume of the cube is 1/2 x 1/2 x 1/2 = 1/8

length x width x height = volume

1x2x2.5=5

2 1/2 = 2.5 because 1/2=0.5

to divide fractions multiply the reciprocal. The reciprocal is the fraction flipped over

5 / 1/8 = 5 x 8/1

Answer:

g = -2

Step-by-step explanation:

g = -5r + 13        Substitute 3 for r into the equation

g = -5(3) + 13     Multiply in the parentheses

g = -15 + 13        Add

g = -2

Solution is 10. How?

Answer:

Answer:

A

Step-by-step explanation:

Here you can check by trying points along the number line that are not included in the other number line. For example, x = -3 is included in A but not in B and x = -5 is included in B but not in A.

If x = -3, the inequality 5x > -20 is true because -15 > -20.

If x = -5, the inequality 5x > -20 is false because -25 is not > -20.

There for the answer should include x = -3 and not include x = -5, so A.

Answer:

The value of z test statistic is 2.871.

Step-by-step explanation:

We are given that a software firm survey of 564 randomly selected adults showed that 56​% of them would erase all of their personal information online if they could. Find the value of the test statistic.

Let p = population proportion of adults who would erase all of their personal information online if they could.

So, Null Hypothesis, [tex]H_0[/tex] : p [tex]\leq[/tex] 50%      {means that adults who would erase all of their personal information online if they could is less than or equal to 50%}

Alternate Hypothesis, [tex]H_A[/tex] : p > 50%     {means that majority of adults would erase all of their personal information online if they could}

The test statistics that would be used here One-sample z test for proportions;

                            T.S. =  [tex]\frac{\hat p-p}{\sqrt\frac{\hat p(1-\hat p)}{n} {} }[/tex]  ~ N(0,1)

where, [tex]\hat p[/tex] = sample proportion of adults who would erase all of their personal information online if they could = 56%

           n = sample of adults taken = 564

So, the test statistics  =  [tex]\frac{0.56-0.50}{\sqrt\frac{0.56(1-0.56)}{564} {} }[/tex]

                                       =  2.871

The value of z test statistic is 2.871.

  D.  Each digit has a value 10 times the value of the digit to its right and 1/10 of the value of the digit to its left

Step-by-step explanation:

Digits increase in value by a factor of 10 for each place you move to the left. Hence a digit to the right has 1/10 the value.

_____

Comment on place value

The multiplier for a base-10 (decimal) number system is 10 as you move one place to the left. In some other base, the multiplier is that base. In a binary (base-2) number system, each "bit" increases in value by a factor of 2 as you move to the left.

Therefore, the "Choice D" is the only correct answer.

Answer:

0.5 pounds is one game

2 pounds is one textbook

Step-by-step explanation:

g = games

t = textbooks

Let's start with how much a game weighs. We know that when Chad added two more games the weight of the box increased by one pound (it was previously 21 pounds and then went to 22 when the two games were added). This means one game equals half of a pound (or 0.5 lbs.)...

[tex]2g = 1[/tex]

[tex]\frac{2g}{2} = \frac{1}{2}[/tex]  -> if you divide one side by two, you must do the same to the other.

[tex]g = \frac{1}{2} = 0.5[/tex]

Now that we know the weight of the games, we can figure out the weight of the textbooks.

[tex]6g + 9t = 21[/tex] -> 6 games and 9 textbooks weigh 21 pounds.

Plugging in that each game is 0.5 pounds...

[tex]6(0.5) + 9t = 21[/tex]

[tex]3 + 9t = 21[/tex]

[tex]3 - 3 + 9t = 21 - 3[/tex]

[tex]9t = 18[/tex]

[tex]\frac{9t}{9} = \frac{18}{9}[/tex]

[tex]t = 2[/tex]

That means that each textbook equals 2 pounds.

Answer:

24618 mm^3

Step-by-step explanation:

V = pi r^2 h

We know the diameter

r = d2/ = 28/2 = 14

V = pi (14)^2 (40)

Approximating pi to 3.14

V = (3.14 ) 14^2 *40

V =24617.6

Rounding to the nearest whole number

V = 24618

Answer:

Since M1 has the higher probability of being in the desired range, we choose M1.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Two machines M1, M2 are used to manufacture resistors with a design specification of 1000 ohm with 10% tolerance.

So we need the machines to be within 1000 - 0.1*1000 = 900 ohms and 1000 + 0.1*1000 = 1100 ohms.

For each machine, we need to find the probabilty of the machine being in this range. We choose the one with the higher probability.

M1:

Resistors of M1 are found to follow normal distribution with mean 1050 ohm and standard deviation of 100 ohm. This means that [tex]\mu = 1050, \sigma = 100[/tex]

The probability is the pvalue of Z when X = 1100 subtracted by the pvalue of Z when X = 900. So

X = 1100

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1100 - 1050}{100}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a pvalue of 0.6915.

X = 900

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{900 - 1050}{100}[/tex]

[tex]Z = -1.5[/tex]

[tex]Z = -1.5[/tex] has a pvalue of 0.0668

0.6915 - 0.0668 = 0.6247.

M1 has a 62.47% probability of being in the desired range.

M2:

M2 are found to follow normal distribution with mean 1000 ohm and standard deviation of 120 ohm. This means that [tex]\mu = 1000, \sigma = 120[/tex]

X = 1100

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1100 - 1000}{120}[/tex]

[tex]Z = 0.83[/tex]

[tex]Z = 0.83[/tex] has a pvalue of 0.7967.

X = 900

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{900 - 1000}{120}[/tex]

[tex]Z = -0.83[/tex]

[tex]Z = -0.83[/tex] has a pvalue of 0.2033

0.7967 - 0.2033 = 0.5934

M2 has a 59.34% probability of being in the desired range.

Since M1 has the higher probability of being in the desired range, we choose M1.

Answer:

x = 30°

y = 60°

z = 96°

Step-by-step explanation:

Well the angle from the center that intercepts 120° is equal to 120° since it is a central angle.

y = 60° because oof supplementary angles.

The measure of z is 48 * 2 because the 48° is an inscribed angle.

z = 96°

And, the arc that angle y intercepts is also the arc the x intercepts.

That arc is 60° because 180° - 120° = 60°

x is an inscribed angle, so x = 1/2 * 60°

x = 30°

The answer to this problem is 1/6.

The share of the pizza each friend will have is 1 / 6.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that three friends equally share 1/2 of a pizza. The fraction of the pizza shared by each friend will be:-

Fraction of pizza = ( 1 / 2 ) x ( 1 / 3 )

Fraction of pizza = ( 1 / 6 )

Therefore, the share of the pizza each friend will have is 1 / 6.
