Divide. Give the exact answer, written as a decimal:
9,350.1 divided by 27

Answers

9350.1 ÷ 27 = 346.3

346.3 should be the answer

Final answer:

To divide 9,350.1 by 27, use long division to obtain an approximate decimal quotient of 346.30037.

Explanation:

To divide 9,350.1 by 27, we can use long division:

Divide the first digit of the dividend (9) by the divisor (27): 9 ÷ 27 = 0.33333 (rounding to 5 decimal places).
Multiply the quotient obtained in the previous step (0.33333) by the divisor (27): 0.33333 × 27 = 8.99991 (rounding to 5 decimal places).
Subtract the product obtained in the previous step (8.99991) from the first digit of the dividend (9): 9 - 8.99991 = 0.00009 (rounding to 5 decimal places).
Bring down the next digit of the dividend (5).
Repeat steps 1-4 until there are no more digits in the dividend.

Therefore, 9,350.1 divided by 27 is approximately 346.30037 (rounded to 5 decimal places).

An automated car wash can wash 30 cars in 5 hours. How long would it take to wash 120 cars? A. 15 h B. 20 h C. 25 h D. 30 h

Answers

An automated car wash can wash 120 carsin 20 hours.

What is expression?

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that an automated car wash can wash 30 cars in 5 hours.

Now, an automated car wash can wash 30 cars in 5 hours.

Then, 1 car can be washed in (5/30) hours.

So, 120 cars will take (5/30 x 120) hours

(5/30 x 120)

5 x 4

20 hours

Therefore, an automated car wash can wash 120 carsin 20 hours.

How do I find the missing measurements?

Answers

Answer:

CD = 10

AD = 22

EC = 13

AC = 26

∠CAD = 23°

∠BAC = 47°

∠ADC =110°

Step-by-step explanation:

A parallelogram is a quadrilateral with two sets of opposite parallel lines.

Which mean in ABCD parallelogram given AB is parallel to DC and BC is parallel to AD.

Now lets find the values required,

CD = AB (Opposite sides are equal in length)

But, AB= 10 (given) therefore CD = 10.

AD = BC (Opposite sides are equal in length)

But, BC= 22 (given) therefore AD = 22.

EC = AE (Diagonals bisect each other)

But, AE= 13 (given) therefore EC = 13

AC = AE + EC

= $13+13$

AC = $26$

∠CAD = ∠BCA (Alternate interior angles are equal)

But, ∠BCA = 23° therefore, ∠CAD = 23°

∠BAC = ∠ACD (Alternate interior angles are equal)

But, ∠ACD = 47° therefore, ∠BAC = 47°

∠ADC + ∠BCD = 180° (Consecutive interior angles)

But, ∠BCD = 23°+47°=70°

∠ADC = 180°- ∠BCD

=180°-70°

∠ADC =110°

Is diameter and radius the same thing

Answers

radius* 2=diameter so no diameter and radius aren't the same thing because radius is half the distance across the circle and diameter is the full distance across the circle.

NO!!!!!!
diameter is the length across the circle
radius is the length from the center of the circle to the outside
radius = r
diameter= d
d=2r

How many fourths in 4 1/4

Answers

14 fourths, because since 4 fourths make up 1, we would multiply 4 times 4, which gives us 16, and then add the extra 1/4. =)

To determine the number of fourths there are in 4 1/4. Remember that 1+1+1+1 equals 4. Each of the 1's can be written as 1/4+1/4+1/4+1/4. And because 1 = 4 1/4's. Then 4 1's = 16 1/4's. But remember these 16 1/4's are only for the number 4. You must also add the one more 1/4. Altogether there are 17 1/4's present. An easier way to think of this is to convert 4 1/4's into an improper fraction. To determine the number of fourths or 1/4's are present in 4 1/4.
