[FIRST TO ANSWER GETS BRAINLIEST] Here is a rectangle ABCD. The length of the rectangle is increased by 10%. The width of the rectangle is increased by 5%. Find the percentage increased in the perimeter of tge rectangle.

Answers

Answer 1

new length = 30x110% = 33cm
new width = 20x105% = 21cm

original perimeter = 30x2 + 20x2
= 60 + 40 = 100
new perimeter = 33x2 + 21x2
= 66 + 42 = 108

increase in perimeter = 108-100 = 8
percentage increase = 8/100 x 100% = 8%

The answer is B.

Step-by-step explanation:

4 is a multiple of 2, which explains the reasoning of answer choice B.

Answer choice A is wrong because 2 is Not a multiple of 4.

Answer choices C and D are incorrect because it takes multiple steps to solve for x and substitute into the other equation. They claim that it takes on step to solve for x, but it would take 2 steps to solve for x.

Mr. Carson makes $21.50 an hour. He works 8 hours a day and works 5 days a week.

Answers

Answer:

$860

Step-by-step explanation:

21.50 times 8 = 172

172 times 5 = 860

CallmeCarson lol

Answer:

860$

Step-by-step explanation:

In order to find the answer to this question you need to multiply the amount of hours Carson worked to the amount of days he worked and then you need to multiply that by the amount he gets paid per hour.

[tex]21.50 = ph[/tex]

[tex]hours=8[/tex]

[tex]days = 5[/tex]

[tex]8\times5=40[/tex]

So he worked 40 hours a week

[tex]40 \times21.50 = 860[/tex]

Therefore Mr.Carson has made 860$ that week.

a. 0.860
b. 0.802
c. 0.057
d. 0.198

Answers

Answer:

The answer to this question would normally be, 85.96%, though that isnt an answer choice so the closest thing to it would most likely be answer choice A.

Using the binomial approximation to the normal, it is found that:

0.86 probability that at most 60 say yes, given by option a.

------------------------

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value is:

[tex]E(X) = np[/tex]

The standard deviation is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

----------------------------

Normal probability distribution

Problems of normally distributed distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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. Each z-score has a corresponding p-value.The p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.The probability that the measure is greater than X is 1 subtracted by the p-value.

When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex], if [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex].

----------------------------

64% use services, thus, [tex]p = 0.64[/tex]87 people are sampled, thus, [tex]n = 87[/tex]

The mean and standard deviation are given by:

[tex]\mu = E(X) = np = 87(0.64) = 55.68[/tex]

[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{87(0.64)(0.36)} = 4.4771[/tex]

Using continuity correction, the probability that at most 60 use is [tex]P(X \leq 60 + 0.5) = P(X \leq 60.5)[/tex], which is the p-value of Z when X = 60.5, thus:

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

[tex]Z = \frac{60.5 - 55.68}{4.4771}[/tex]

[tex]Z = 1.08[/tex]

[tex]Z = 1.08[/tex] has a p-value of 0.86.

Suppose a population grows according to a logistic model with initial population 1000 and carrying capacity 10,000. If the population grows to 2500 after one year, what will the population be after another three years?

Answers

Answer:

7500

Step-by-step explanation:

1 year= 2500

3 years= x

So we got

2500 × 3 = 7500

The population after another three years will be 15,625.

What is an exponent?

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

Assume a populace becomes as per a strategic model with starting populace of 1,000 and conveying limit of 10,000.

If the population grows to 2500 after one year. Then the increasing factor is given as,

b = 2,500 / 1,000

b = 2.5

Then the equation is given as,

y = 1,000 × (2.5)ˣ

Then the population after another three years will be given as,

y = 1,000 × (2.5)³

y = 1,000 × 15.625

y = 15,625

The population after another three years will be 15,625.

Given triangle MAT is an isosceles triangle and point H is the midpoint if MT. Prove triangle MHA is congruent to triangle THA

Answers

Answer:

There is everything in the image

The Side-Angle-Side postulate is satisfied. Then the triangle ΔMHA and ΔTHA are congruent with each other.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.

A triangle MAT is an isosceles triangle and point H is the midpoint of MT.

In triangle ΔMHA and ΔTHA, we have

AH = AH (Common sides)

MH = HT (H is the midpoint of MT)

∠AMH = ∠ATH (Isosceles angles)

The Side-Angle-Side postulate is satisfied. Then the triangle ΔMHA and ΔTHA are congruent with each other.

Earnings when selling $2175:??

Earnings when selling $x: ??

Answers

Answer:

[tex]Earnings = 308.75[/tex] ---- (a)

[tex]Earnings = 300 + 0.05x[/tex] -- (b)

Step-by-step explanation:

Given

[tex]Base\ Salary = 300[/tex]

[tex]Commission = 5\%[/tex]

Solving (a): Sales of $2175 in a week.

His total earnings is calculated as thus:

[tex]Earnings = Base\ Salary + Commission * Sales[/tex]

[tex]Earnings = 300 + 5\% * 2175[/tex]

[tex]Earnings = 300 + 108.75[/tex]

[tex]Earnings = 308.75[/tex]

Solving (b): Sales of $x in a week.

His total earnings is calculated as thus:

[tex]Earnings = Base\ Salary + Commission * Sales[/tex]

[tex]Earnings = 300 + 5\% * x[/tex]

Convert percent to decimal

[tex]Earnings = 300 + 0.05 * x[/tex]

Joe, Kent, Bryan and Julie scored an average of 63 mark in Mathematics test. If we know that Julie's score qas 25% of Joe's score. Bryan scored 10 more marks thsn Joe and Kent scored 18 fewer marks than Joe. What is the total score of kent and bryan?

Answers

J = Julie
B = Bryan
O = Joe
K = Kent

(J + B + O + K) / 4 = 63

J = .25O
B = O + 10
K = O - 18

Substitute:
((.25O) + (O + 10) + O + (O - 18)) / 4 = 63
(3.25O - 8) / 4 = 63
3.25O - 8 = 252
3.25O = 260
O = 80

K = O - 18
K = 80 - 18
K = 62

B = O + 10
B = 80 + 10
B = 90

Therefore,
B + K = 152
