A number times nine + four gives you fifteen if you have time

Answer:

B  y = 1.1x^2 +4.2x - 4.9

Step-by-step explanation:

For this one, try plugging in 1.

y = 1.1(1)^2 + 4.2(1) - 4.9

1.1 + 4.2 - 4.9

1.1 + 4.2 = 5.3

5.3 - 4.9 = 0.4

0.4 is the closest for (1, 0.3)

So the correct answer is B. All the others don't make sense and are not close enough.

Answer:

Answer:

Step-by-step explanation:

To change a decimal into a percent you multiply by 100.

If there is a fraction that you need to convert into a percent. Completely divide the fraction. 4/5 = 0.8 then multiply by 100 you get 80%. This means that 4 is 80% of 5

Answer:

how to get a percentage from a decimal is when you take the decimal point and move it twice to the left

Step-by-step explanation:

for example

.07 = 7%

does that make sense?

Answer:the answer is -6.2

Step-by-step explanation:

Answer:

-6.2

Step-by-step explanation:

13.7 - 19.9 = ?

rewrite (optional)

-19.9 + 13.7 = -6.2

Answer:

Less than

Step-by-step explanation:

Its less than because the angle of LS is 98 while MS is 95, so LS is longer

Step-by-step explanation:

The line between -3 and 2 is not shaded so it is not -3 < x < 2. Instead, the lines to the left of -3 and to the right of 2 are shaded.

Therefore the correct answer is x < -3 or x > 2.

Answer:

x = 3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given y varies directly as x², then the equation relating them is

y = kx² ← k is the constant of variation

To find k use the condition y = 27 when x = 3 , then

27 = k × 3² = 9k ( divide both sides by 9 )

3 = k

y = 3x² ← equation of variation

When y = 81, then

81 = 3x² ( divide both sides by 3 )

27 = x² ( take the square root of both sides )

x = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = 3[tex]\sqrt{3}[/tex]

Answer is

4.89

Step-by-step explanation

Answer:

a) If both the numerator and the denominator are increased by 2, the fraction becomes?

= 4/5

b) What is the original fraction?

= 2/3

Step-by-step explanation:

The ratio of the numerator to the denominator of a fraction is 2 to 3.

a) If both the numerator and the denominator are increased by 2, the fraction becomes .

2:3 = 2/3

We are told that both numerator and denominator are increased by 2, hence:

2 + 2/3 + 2

= 4/5

b) What is the original fraction?

The ratio of the numerator to the denominator of a fraction is 2 to 3.

Hence, the original fraction is:

2:3 = 2/3

Step-by-step explanation:

Y is greater then -4

ie(-3,-2,-1,0,1,2,3,....)

Answer:

55

13(3/4)=55/4

55/4/4=55

The slope-intercept form: y = mx + b

So we need to "solve" given equation for y

3.3x - 3y = 2.4           {subtracting 3.3x from both sides}

- 3y = 2.4 - 3.3x        {dividing both sides by (-3)}

  y = -0.8 + 1.1x

Therefore:

The decimal for this fraction is 5.5

Answer:

The decimal for the fraction is 5.5.

Step-by-step explanation:

Between 20/4 and 24/4, you can safely assume that the fraction provided is between 5 and 6 which makes part of your answer as a whole number 5.  Since 22/4 is exactly between the fractions mentioned above, it is safe to assume that the decimal is 5.5 with .5 being half of the number.

Slope:

8

y-intercept:

2

Answer:

All real numbers are solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(3x+2)=16x+7−4x+1

(4)(3x)+(4)(2)=16x+7+−4x+1(Distribute)

12x+8=16x+7+−4x+1

12x+8=(16x+−4x)+(7+1)(Combine Like Terms)

12x+8=12x+8

12x+8=12x+8

Step 2: Subtract 12x from both sides.

12x+8−12x=12x+8−12x

8=8

Step 3: Subtract 8 from both sides.

8−8=8−8

0=0

Answer:

$1, 512

This is how:

1) Michael works 28 hours in one week. So how many hours does he work in 6 weeks?

So you need to calculate : 28 × 6 = 168

SO THIS IS THE TOTAL NUMBER OF HOURS FOR 6 WEEKS.

2) because Michael gets paid $9 PER HOUR :

You will need to multiply the amount of money he receives with the total number of hours he works.

168 × 9 = $ 1, 512

He earns $1,512 in 6 weeks

Answer:

Quantity zero just means that there is no amount of something. If I had zero dollars, it means I have no money at all.
