1. A rectangle has a length of 5cm and a height of 4cm.

a. Find the area of the rectangle

b. Find the perimeter of the rectangle.

c. A scale factor of .5 is used to reduce the rectangle. What is the new area?

d. A scaled factor of 2 is used to increase the triangle. What is the new area?

Answers

Answer 1

Answer:

a

20cm squared

b

18cm

c

5cm

d

80cm

Step-by-step explanation:

a

Area is height multiplied by length in a regular quadrilateral

b

Perimeter is calculated by adding all the sides together

c

0.5 is effectively halving, so instead of 4 multiplied by 5 it is 2 multiplied by 2.5

d

2 is effectively doubling, so instead of 4 multiplied by 5 it is 8 multiplied by 10

Answer 2

Answer:

20 cm²18 cm5 cm²80 cm²

Step-by-step explanation:

Q1(a)

Area = length x heightArea = 5 x 4Area = 20 cm²

Q1(b)

Perimeter = 2(length + height)Perimeter = 2(5 + 4) = 2(9)Perimeter = 18 cm

Q1(c)

New dimensions are : 5/2 = 2.5 and 4/2 = 2New Area = 2.5 x 2New Area = 5 cm²

Q1(d)

New dimensions are : 2 x 5 = 10 and 2 x 4 =  8New Area = 10 x 8New Area = 80 cm²

Step-by-step explanation:

|5x+2|=8 this mean that:

5x+2=8 and 5x+2=-8

5x+2-2+8-2 and 5x+2-2=8-2

you have $5600. The best interest rate you can find is 3%
compounded quarterly, for how long should you deposit the money in order
have $9600? how many years

Answers

Answer:

18 years

Step-by-step explanation:

The formula for computing accrued amount A for a principal of P at an interest rate of r(in decimal) compounded n times in a year for t years is given by

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

Note that r is percentage converted to decimal. So 3% = 3/100 = 0.03

We can rearrange the above equation to:

[tex]\frac{A}{P} = (1 + \frac{r}{n})^{nt}[/tex]

Taking logs on both sides

[tex]log(\frac{A}{P}) = log(1 + \frac{r}{n})^{nt}[/tex]

This gives

[tex]log(\frac{A}{P}) =nt \times log(1 + \frac{r}{n})\\So,\\nt = \frac{log(\frac{A}{P})}{ log(1 + \frac{r}{n})}[/tex]

In this particular problem, n = 4, , A= 9600, P = 5600, r =0.03, so r/n = 0.03/4 = 0.0075

1 + r/n = 1+0.0075 = 1.0075

4t = log(9600/5600)/log(1.0075) = log(1.714) / log(1.0075) = 0.234 /0.00325 = 72

t = 72/4 = 18 years

Did I do it right? If the measure of ∠DAB=51∘, ∠CAB=x, and ∠DAC=x+1, find the measure of ∠CAB

Answers

If the measure of angles ∠DAB = 51° and the value of x is 25. Then the measure of angle ∠CAB will be 25°.

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

If the measure of angles ∠DAB = 51°, ∠CAB = x, and ∠DAC = x + 1.

Then the measure of angle ∠CAB will be

We know

∠CAB + ∠CAD = ∠DAB

x + x + 1 = 51

        2x = 50

          x = 25

Then the measure of the angle ∠CAB will be

∠CAB = x

∠CAB = 25

∠CAB = 25°

Answers

Answer:

The teacher bought 113 crayons.

Answer: 113 Crayons

Step-by-Step Explanation:

Total packets of crayons = 12
7 of them had => 9 crayons
5 of them had => 10 crayons
Total number of crayons = ?

Therefore,
= (7 * 9) + (5 * 10)
= (63) + (50)

The student body of a large university consists of 60% female students. A random sample of 8 students is selected. What is the probability that among the students in the sample at least 6 are female?

Answers

Using the binomial distribution, it is found that there is a 0.3154 = 31.54% probability that among the students in the sample at least 6 are female.

What is the binomial distribution formula?

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.

In this problem:

The student body of a large university consists of 60% female students, hence p = 0.6.A random sample of 8 students is selected, hence n = 8.

The probability that among the students in the sample at least 6 are female is given by:

[tex]P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8)[/tex]

In which:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 6) = C_{8,6}.(0.6)^{6}.(0.4)^{2} = 0.2090[/tex]

[tex]P(X = 7) = C_{8,7}.(0.6)^{7}.(0.4)^{1} = 0.0896[/tex]

[tex]P(X = 8) = C_{8,8}.(0.6)^{8}.(0.4)^{0} = 0.0168[/tex]

Then:

[tex]P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) = 0.2090 + 0.0896 + 0.0168 = 0.3154[/tex]

0.3154 = 31.54% probability that among the students in the sample at least 6 are female.

Answers

10 students like to watch movies.

first, to find what a sixth of 30 is, you have to divide your number by the denominator (30/6) which is 5, then add that to half of thirty (15) to find out how many kids DONT watch movies. 15+5=20, and to find how many kids are remaining you have to do 30-20, which equals 10, meaning there are a total of ten kids who like to watch movies.

15ml of Tylenol 3 to given every 4-6 hours. Your research indicates that there are 12mg of codeine per 5ml of liquid and that the safe dosage is between 0.5 and 1mg/kg/every 4-6 hours. Is this prescription safe for your child? Explain. If not, what would a safe dose be?

Answers

Answer:

If the safe dose is .5 to 1 mg/kg/dose, the safe limit depends on the side of the child.  Using the more conservative limit of .5mg/kg, you have 36mg(kg/.5mg)=72kg, which is roughly 160lbs,  Even with the upper limit of 1mg/kg, you still have 36mg(kg/1mg) = 36kg, or 80lbs, which is a larger child.  I would say this dose isn't "safe", but you really need the weight of the child to calculate what is a safe dose.
