The length of a rectangle is 20 meters and the width is 4 meters. What is the perimeter of the rectangle? Do not include units in your answer.

Answers

Answer:

[tex]\boxed {\boxed {\sf 48 \ meters }}[/tex]

Step-by-step explanation:

The perimeter is the sum of the side lengths.

A rectangle has 4 sides: 2 lengths and 2 widths, so the perimeter formula is

[tex]p= 2l+2w[/tex]

The length is 20 meters and the width is 4 meters.

[tex]p= 2(20 \ m )+ 2(4 \ m )[/tex]

Multiply.

[tex]p= 40 \ m + 8 \ m[/tex]

Add.

[tex]p= 48 m[/tex]

The perimeter of the rectangle is 48 meters.

2. The ratio of the angle measures in a
triangle is 1:12:17. What is the measure of
smallest angle?

Answers

Answer:

6 degrees

Step-by-step explanation:

x + 12x + 17x = 180

x = 6

The angles are 6 : 72 : 102 so the smallest is 6 degrees.

Answer:

sum of all angles = 180

given angle 1 X., 12 X, 17 X

SO 1 X + 12 X + 17 X= 180

13 X+17 X =180

30 X = 180

X=180\30

X =6

ANS =6

HOW; PUT X = 6 APPLY TO 1 X., 12 X, 17 X

1 X=1×6= 6

12X = 12×6 =72

17 X = 17 ×6 =102

ANS = 6

Step-by-step explanation:

4. (5 x 3) x 2 = 5 x (3 x 2) is an example of which property?
A) Commutative Property for Addition
B) Associative Property for Multiplication
O C) Distributive Property for Multiplication
D) Commutative Property for Multiplication

Answers

Answer:

B, Associative property for multiplication

Step-by-step explanation:

Commutative property means the numbers can be multiplied in any order, so the (5 x 3) x 2 could be written as 3 x 5 x 2 and would be the same.

Associative property deals more with groupings of terms/numbers. Since the order of the numbers stayed the same, and the parentheses are moved, this is an example of the associative property.

The answer would be b

Clinical literature reports that the duration of a typical cold is roughly 18 days. Researchers wanted to know if people tend to underestimate the duration of a typical cold, on average. They surveyed a random sample of 352 healthy adults in Georgia and asked them how long they think that a typical cold lasts. The researchers reported a 95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.
Which of the following is the correct interpretation for this confidence interval?
a. We are 95% confident that the sample mean duration is between 6.9 and 8.2 days.
b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.
c.There is a 95% chance that the mean duration of another random sample from this population would be between 6.9 and 8.2 days.
d. There is a 95% chance that a randomly selected individual from this population would give a response between 6.9 and 8.2 days.

Answers

Answer:

b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.

This means that we are 95% sure that the true duration of a typical cold(population mean) for all health adults in Georgia is between 6.9 and 8.2, which means that the correct answer is given by option b.

Hope this helps!

explanation:

we solve the inequality and to do that we must first subtract 12 from both sides, which gets us -x<-4, then we divide both sides by -1, which gives us x>4, since we have to flip the sign when we divide by a negative. when we graph this, there will be a circle around 4 and the arrow pointing to the right, since it's greater than.
