Answer:

13 tens

Step-by-step explanation:

Given data

We are given that the traveled 1,355 miles of distance

Hence the number of tens of hundred is

=1,355/100

=13.55

Hence in all, there are 13 tens of hundreds

Answer:

[tex]\boxed {\boxed {\sf \frac{ 243}{8} \pi , 95.3775, or \ 95.42587686 \ m^2 }}[/tex]

Step-by-step explanation:

When given the central angle in degrees, the formula for sector area is:

[tex]A=\frac{ \theta}{360} * \pi r^2[/tex]

where θ is the central angle and r is the radius.

We are given the diameter, so we must calculate the radius. The radius is half the diameter.

The diameter is 18 meters.

Now we know all the variables:

Substitute the values into the formula.

[tex]A=\frac{ 135}{360} * \pi (9)^2[/tex]

Solve the exponent first.

[tex]A=\frac{ 135}{360} * (81 \ m^2) \pi[/tex]

Solve the fraction.

[tex]A=\frac{ 3}{8} * (81 \ m^2) \pi[/tex]

Multiply the two rational numbers.

[tex]A=\frac{243}{8} \pi \ m^2[/tex]

The answer can be left like this, in terms of pi, or can be multiplied.

[tex]A=\frac{243}{8} *3.14 \ m^2[/tex]

[tex]A= 95.3775 \ m^2[/tex]

[tex]A= 95.42587685 \ m^2[/tex]

The area is 243/8 π, 95.3775, or 95.42587685 square meters.

Answer:

Denver should be experiences balmy weather on day 3. Temps vary depending on the month, but overall no storms, and fairly clear weather should be present.

Step-by-step explanation:

A higher pressure system is moving closer to Denver, making for sunnier and calmer weather. It also seems like the nice H should stick for around 2-5 days if the low and high pressure systems continue in what seems to be a slight loop, the low pressure system will probably be moving to the Northeast soon. Overall Denver should be experiencing nice weather, perhaps a bit colder because of the cold front that seems to have sweeped through before Day 1.

Answer:

54 muffins

Step-by-step explanation:

Given that:

Cups of flour used to make recipe = 3 1/3 cups

Total cups of flour = 10 cups

Number of muffins per recipe = 18

Number of recipes that can be made from 10 cups of flour :

Total cups of flour / cups of flour per recipe

10 ÷ 3 1/3

10 ÷ 10/3

10 * 3/10

30 /10

= 3 recipes

Total number of muffins :

Number of muffins per recipe * number of recipe

18 * 3 = 54 muffins

Answer:

The four investments are possible.

Step-by-step explanation:

Investor has 200k to invest,

The 4 investment are:

1.  Apple inc

2. B  inc

3. C inc

4.  D inc

Assuming the other three investments are B, C and D.

If 50k is invested in Apple inc, how much is left?

200k -50k = 150k

This remaining 150k can shared equally amongst the other three investments ;

150/ 3 = 50

Therefore each investment will get 50k each.

Answer:

Shape: Approximately Normal

Center: 20 minutes

Variability: 6.5 minutes.

Using statistical concepts, it is found that the distribution is normal, with mean (center) of 20 minutes, and standard deviation of 6.5 minutes.

When a constant is added to a normal variable, the distribution remains normal and the standard deviation remains constant, while the constant is added to the mean.

In this problem, a constant of 5 minutes is added to a normal variable with mean of 15 minutes and standard deviation of 6.5 minutes, hence, the distribution is:

Normal, with mean (center) of 20 minutes, and standard deviation of 6.5 minutes.

Answer:

Salome is 29 inches tall.

Step-by-step explanation:

Each feet has 12 inches.

Salome:

Answer:

The answer is 6.

Step-by-step explanation:

you have 3/4 divided by 1/8, first you find a common denominator, which is 8. Second you do 3 x 2 and 4 x 2, you should get 6/8 divided by 1/8, and 6 divided by 1 is still 6.

Answer:

6

Step-by-step explanation:

3 /4   × 8 /1 =

3×8/4×1=24/4

3x8 is the numerator 4x1 is the denominator

24/4=6

Answer and explanation:

If we are given a table on calories burned by Robyn on weekdays from Monday to Friday and on this table Robyn burnt 500 calories on Monday and burnt 400 calories on Wednesday, then we are required to determine the ratio of calories burnt on Wednesday to calories burnt on Monday:

Calories burnt on Wednesday = 400

Calories burnt on Monday =500

Ratio of calories burnt on Wednesday to calories burnt on Monday =400/500=4/5

Ratio =4:5

Answer:

D.

Step-by-step explanation:

m<F = m<B - Corresponding Angles Theorem

m<B + m<A = 180 - Adjacent Angles Theorem

180 - 105 = m<A

75 = m<A; therefore, m<A = 75.

Answer:

D.

Step-by-step explanation:

Because F and C are consecutive angles, they add up to 180°. So 180-105=75. Angle C is 75, which makes B wrong. After finding that C is 75°, then you use the verticle angles theorem to show that angle A is 75°. Hope this helps you.
