Answers

Answer 1

Answer:

4

Step-by-step explanation:

2+2-2+4÷2

we go through

P- parentheses

E- exponents

M- multiplication

D- division

A- addition

S- subtraction

also note that we read it from left to right becaue × is not more important than ÷ and same goes to + and -

First step

2+2-2+(4÷2) --> 2+2-2+2

then

2+2-2+2 --> 4-2+2

then

Answer: Julio will have less pages to read. Julio has 30, Jake has 48

Step-by-step explanation:
This is what we know...
Jake: 168 pg at 24 pg / day If Julio reads at a rate of 1 1/4 what Jake reads we take the 24 pg and multiply that by 1.25 24 x 1.25 = 30 So now you know the Julio reads 30 pgs each day. Now you divide Jake's 168 pgs by 24 and you get that it would take him 7 days to read the book. At 5 days Jake still has 48 pages to read. Now, Julio's 180 pages divided by his 30 pages / day which will be 6 days to complete his book. At 5 days he will have only 30 pages to read.

What are the next three terms in the given sequence?
3, 16, 29, 42,
A) 54, 66, 78
B)
55, 68,81
C) 1,2,3
D) 55,70,83

Answers

Answer:

B) 55, 68,81

Step-by-step explanation:

42-29=13

29-16= 13

So 42 + 13= 55

55+ 13= 68

68+ 13= 81

Answer:

B)  55, 68, 81

Step-by-step explanation:

Given sequence:  3, 16, 29, 42

To determine if the sequence is arithmetic or geometric, work out the difference in the terms.

[tex]\sf 3 \underset{+13}{\longrightarrow} 16 \underset{+13}{\longrightarrow} 29 \underset{+13}{\longrightarrow} 42[/tex]

This sequence adds 13 each time, so as the common difference is constant, it is an arithmetic sequence.  To find the next term in the sequence, simply add 13 to the last term:

42 + 13 = 55

55 + 13 = 68

68 + 13 = 81

Therefore, the next three terms in the given sequence are 55, 68, 81

To solve this using the general form of an arithmetic sequence:

[tex]a_n=a+(n-1)d[/tex]

where:

[tex]a_n[/tex] is the nth terma is the first termd is the common difference between terms

Given:

a = 3d = 13

[tex]\begin{aligned}\implies a_n & =3+(n-1)13\\ & = 3+13n-13\\ & = 13n-10\end{aligned}[/tex]

Therefore, the next 3 terms in the sequence are:

[tex]\implies a_5=13(5)-10=55[/tex]

[tex]\implies a_6=13(6)-10=68[/tex]

[tex]\implies a_7=13(7)-10=81[/tex]

What is a quadratic equation?

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Function representing the cost to the manufacturer is,

C(x) = -20x²+ 48000x + 19351

A function that represents the revenue generated is,

R(x) = -23x² + 114000x

Function representing profit to the company,

Profit = Revenue generated - Cost price

        = -23x² + 114000x - ( -20x²+ 48000x + 19351)

        = -23x² + 20x² + 114000x - 48000x - 19351

P(x)  = -3x² + 66000x - 19351

Since this function is a quadratic function, the maximum price generated would be x = -b/2a

From the given quadratic function, a = (-3), b = 66000 and c = -19351

x = - 66000/ 2(-3)

x = -66000/-6

x = 11000

x = 11000 the profit to the company will be maximum.

That means pear company should produce 11000 phones for the maximum profit.

Answer:

Total amount = $575.00I = PRT/100 = $75.00Equation:

Total amount = interest + principle

Step-by-step explanation:

Formula:- I = PRT/100

Where,

I is interestP is principleR is rateT is time

⇒ I = 500×5×3/100

Hey there!

Question no.9:

Farmer Brown had 25 cows and chickens. They had a total of 72 legs. How many cows and how many chickens did Farmer Brown have?

Solution:

Let the number of cows be "x" and the number of chickens be "y".

According to question,

x + y = 25 4x + 2y = 72 -->(ii)

=> 4(x + y) = 25 × 4

=> 4x + 4y = 100 -->(i)

By Elimination method,

Equation (i) - (ii)

(4x + 4y) - (4x + 2y) = 100 - 72

=> 4x + 4y - 4x - 2y = 28

=> 2y = 28

=> y = 28/2

=> y = 14

Putting the value of "y" in Equation (ii)

4x + 2y = 72

=> 4x + 2 × 14 = 72

=> 4x + 28 = 72

=> 4x = 72 - 28

=> 4x = 44

=> x = 44/4

=> x = 11

Therefore,

Total number of cows = 11

Total number of chickens = 14

Note: In the second equation of this question I've taken 4 and 2.

The reason behind it is simple. Since, I've assumed the number of cows is "x" and a cow has four legs that why infront of "x" I've put 4.

And a chicken has 2 legs and I've assumed it as "y" therefore infront of "y" I've put 2.

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

Question no.10:

Farmer Brown had 28 cows and chickens. They had a total of 96 legs. How many cows and how many chickens did Farmer Brown have?

Solution:

Let the number of cows be "x" and the number of chickens be "y".

According to question,

x + y = 28 4x + 2y = 96 -->(ii)

=> 4(x + y) = 28 × 4

=> 4x + 4y = 112 -->(i)

By Elimination method,

Equation (i) - (ii)

(4x + 4y) - (4x + 2y) = 112 - 96

=> 4x + 4y - 4x - 2y = 16

=> 2y = 16

=> y = 16/2

=> y = 8

Putting the value of "y" in Equation (ii)

4x + 2y = 96

=> 4x + 2 × 8 = 96

=> 4x + 16 = 96

=> 4x = 96 - 16

=> 4x = 80

=> x = 80/4

=> x = 20

Therefore,

Total number of cows = 20

Total number of chickens = 8

Note: In the second equation of this question I've taken 4 and 2.

The reason behind it is simple. Since, I've assumed the number of cows is "x" and a cow has four legs that why infront of "x" I've put 4.

And a chicken has 2 legs and I've assumed it as "y" therefore infront of "y" I've put 2.

Internet Viewing A researcher wishes to estimate the average number of minutes per day a person spends on the Internet. How olo
large a sample must she select if she wishes to be 99% confident that the population mean is within 10 minutes of the sample
mean? Assume the population standard deviation is 38 minutes. Round your final answer up to the next whole number.

Answers

Using the z-distribution, as we have the population standard deviation, it is found that a sample of 96 people must be taken.

What is the margin of error for the z-distribution?

It is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

z is the critical value.[tex]\sigma[/tex] is te population standard deviation.n is the sample size.

In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

Additionally, we have that [tex]\sigma = 38, M = 10[/tex], hence we solve for n to find the minimum sample size needed.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]10 = 2.575\frac{38}{\sqrt{n}}[/tex]

[tex]10\sqrt{n} = 38 \times 2.575[/tex]

[tex]\sqrt{n} = 3.8 \times 2.575[/tex]

[tex](\sqrt{n})^2 = (3.8 \times 2.575)^2[/tex]

n = 95.7

Rounding up, a sample of 96 people must be taken.

what is an area of a trapezoid

Answers

Answer:

144

Step-by-step explanation:

Required area= Area of rectangle +2×(Area of Triangle)

=(10×8)+2×(1/2×8×8)

=80+64=144 in²

Answer:

144 in²

Step-by-step explanation:

To solve for the area of a trapezoid divided into a parallelogram (in this case a rectangle) and two triangles, you calculate the area of each part and add it together.

the area of a triangle = (base • height) / 2

the area of a parallelogram = (base • height)

so:

1. Calculate area of first triangle. 8 • 8 = 64, 64/2 is 32

2. Calculate the area of the second triangle. Since in this situation you have two equal triangles, you multiply the answer to the first part by 2 and get 64 in² again.

3. Calculate the area of the rectangle. 8 • 10 = 80 in²

4. Add the two numbers together. 80 + 64 = 144 in²
