simplify this expression -4.37 x (-5.2) = ?

Answer:

11. 3,396

Step-by-step explanation:

Given:

Circumference of Mars = 10,664 km

Determine the diameter of Mars.

D = 2r

C=2πr

Solution:

Since we do not have the value of r, we will solve for r in terms of C.

C=2πr

10,644 = 2πr

r = 10644/ 2π

r = 1694.04 km

Now that we know the value of r, we can solve for d.

D = 2r

D = 2( 1694.04km)

D = 3,388.09 km

The nearest value is 3,396 km on the choices, but the answer rounded to the nearest km is 3,388 km

Answer:

(4, 8) also known as option B. is the correct answer.

remember

x comes first

y comes second

and

x goes across

y goes up and down

Answer: the answer is ( 4, 8) which is the second choice .

Step-by-step explanation: the 4 is on the x axis line and the 8 is on the y axis line . So coordinates 4,8 represent E on the coordinateplane . HOPE IT HELPS YOU .PLEASE GIVE BRAINLIEST .THANKS .

Answer:

= 1.726 × 10^-5

= 2 x 10^-5

Step-by-step explanation:

Move the decimal to the right. Moving to the right makes the exponent a negative number. Round 1.726 to the nearest whole number as 2.

94,86,95,99,88,90

A. mean is 92

B. mean absolute deviation is 4

C. values differ from the mean by an average of 4

A.

94+86+95+99+88+90=552

552 divided by 6 = 92

mean = 92

C.

94-92=2

92-86=6

95-92=3

99-92=7

92-88=4

92-90=2

2+6+3+7+4+2=24

24 divided by 6 = 4

x + 2.6 = 10.4

- 2.6 -2.6

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

x = 7.8

Answer:

mark brainliest please!!! <33

Step-by-step explanation:

Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing

The standard equation of a line in slope-intercept form is expressed as:

y = mx + b

where:

The nature of the graph is determined by the slope value.

If the slope is positive, the graph is increasing while if the slope is negative, the graph is decreasing.

Given the function y = x - 1, compared with the general equation;

mx = 1x

m = 1

Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing

set as brainliest pls

Answer:

option B

Step-by-step explanation:

we first subtract 4 by both sides to get:

3x < -15

now we just divide by 3 on both sides to get

x < -5

the answer is B

Answer:

see below

Step-by-step explanation:

3x+4 less than or equal to -11

Subtract 4 to get 3x isolated

3x < -15

Because x still has something attached to it, you divide by 3

x is less than or equal to -5

The answer is A. Don't worry

Answer:

1: D

2:B

I belive this is correct if I did the math proprly.

Step-by-step explanation:

Answer:

2.4h+2.2

Step-by-step explanation:

4.5h-7.7+9.9-2.1h

To solve this problem, we need to combine like terms.

Because 2.1h is negative, we can subtract it from 4.5h and get 2.4h.

2.4h-7.7+9.9.

We can do the same thing with -7.7 and 9.9. 9.9-7.7=2.2. We have to stop there because constants, numbers without variables, can't be added or subtracted to coefficients, numbers with variables.

Therefore, the simplified equation is 2.4h+2.2.

Answer:

x ≤ 35/8

Step-by-step explanation:

1. move the constant to the right

2. Calculate 8x  ≤ 56-21

3. Divide 8 from 8x  ≤ 35

x  ≤ 35/8

Answer:

39 - 35 = $4

Step-by-step explanation:

mean: 19+42+35+40+39 = 175

            175/5 = 35

add up all the cost then divide by how many numbers there are.

Median:

list the numbers from lowest to largest

19, 35, 39, 40, 42

then find the number in middle

39

last: 39-35=$4

Answer:

60 cm^3

Step-by-step explanation:

volume = 1/2 * b * h * l

1/2 * 12 * 2.5 * 4 =

60

Answer:

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

There are 3 dimensions 3, 4, and 2. multiply all of these the get the volume. 3 x 4 = 12. 12 x 2 = 24

Answer:

Step-by-step explanation:

In order to solve this, you must use the volume of the cube.

[tex]\underline{\textbf{VOLUME OF THE CUBE FORMULA:}}[/tex]

[tex]\Longrightarrow: \sf{V=L*W*H}[/tex]

Multiply.

Use the order of operations.

PEMDAS stands for:

[tex]\Longrightarrow: \sf{3*2*4}[/tex]

First, do multiply.

[tex]\Rightarrow: \sf{3*2=6}\\\\\\\Rightarrow: \sf{6*4=\boxed{\sf{24}}[/tex]

Answer: 4/50 equals 2/25

Step-by-step explanation:4/50 and 2/25 equal.08. To get it I did 2×2=4 and 25×2=50 to get 4/50 which equals 2/25 or .08

Answer:

.08 or 8/100

Step-by-step explanation:

First I'd change the fraction to an equivalent fraction with 100 as the denominator since we want the number in hundredths.

If you multiply 25 by 4 you get 100, so that would be the denominator.

Since you multiplied the denominator by 4 you'd also have to multiply the numerator, 2. 2 times 4 is 8.

Now your fraction is 8/100, and if you change this into decimal form, you get .08

Answer:

[tex]\sf D.\;\;x=2[/tex]

Step-by-step explanation:

[tex]\sf 3x + 2 = 7x - 6[/tex]

Subtract 2 from both sides:-

[tex]\sf 3x+2-2=7x-6-2[/tex]

Simplify:-

[tex]\sf 3x=7x-8[/tex]

Subtract 7x from both sides:-

[tex]\sf 3x-7x=7x-8-7x[/tex]

Simplify:-

[tex]\sf -4x=-8[/tex]

Divide both sides by -4:-

[tex]\sf \dfrac{-4x}{-4}=\dfrac{-8}{-4}[/tex]

Simplify:-

[tex]\sf x=2[/tex]

Answer:

The total change in the water level is [tex]-\frac{33}{28}[/tex]

Step-by-step explanation:

In order to get the total change in something is to add all the numbers together. So, over that three month period, you add -1 3/4-1/28-15/28. SInce you are adding fractions, it helps to have all the denominators the same. Change -1 3/4 into -49/28. (all I did was turn the fraction into an improper fraction then did  [tex]\frac{7*7}{7*4}=\frac{49}{28}[/tex] )

Now that we have all the same denominators, just add them/combine them.

[tex]-\frac{49}{28} -\frac{1}{28} -\frac{15}{28}[/tex] = [tex]-\frac{33}{28}[/tex]

Answer:

The answer is 9.

Hope this helps.
