If two out of every 10 high school students are licensed drivers, about how many students would be expected to have drivers' licenses in a high school with 615 students?

Answer:

Solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]

Step-by-step explanation:

We need to solve the inequality: [tex]1<\frac{a+7}{-2}[/tex]

We need to solve the inequality, to find the value of a.

Solving the inequality:

[tex]1<\frac{a+7}{-2}[/tex]

First step is Switching both sides (the inequality will be reversed)

[tex]\frac{a+7}{-2}>1[/tex]

The next step is to multiply both sides by -2 and reverse the inequality

[tex]\frac{a+7}{-2}*-2<1*-2\\a+7<-2[/tex]

Now, subtracting 7 on both sides

[tex]a+7-7<-2-7\\a<-9[/tex]

So, solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]

Answer:

ypotenuse squared = adjacent squared + opposite squared

Step-by-step explanation:

sin θ =opposite/hypotenuse

tan θ = opp/adjacent

cos θ = adj/hyp

Pythagoras Theorem states that hypotenuse squared = adjacent squared + opposite squared

Answer:

B

Step-by-step explanation:

A triangle always has a degree total of 180. x+y=116 180-116=64 therefore the last angle, angle c, must be 64 degrees.

Answer: B. 64 degrees

Step-by-step explanation:

∠C = 180° - (∠X + ∠Y)

∠C = 180° - (32° + 84°) = 180° - 116° = 64°

Answer:

It is inversly proportional, there is no constant, the directio is from left to right and from up to down, as x gets larger, y gets less

Step-by-step explanation:

Answer:

y = 2x-4

all the equations are the same as the slope-intercept form is the same for all the equations

Step-by-step explanation:

slope-intercept form:

[tex]y = mx + b[/tex]

2x-3 = y+1

-y+2x-3 = 1

-y = 1-2x+3

-y = (1+3)-2x

-y = 4-2x

y = -4+2x

( commutative property: the number on which we operate can be moved or swapped from their position without making any difference to the answers )

y = 2x-4

Answer:

c.

Step-by-step explanation:

when the fish swam down 55, you moved 55 to the left of zero. then when he swam 30 up, you take that 55 and move it 30 towards to the right. since -55 is greater than 30, your answer is still negative. -55+30=-25.

Answer:

C

Step-by-step explanation:

Answer:

-4x - 10

Step-by-step explanation:

Given the expression -2/3(6x+ 15)

Open the bracket

-2/3(6x+ 15)

= -2/3 (6x) -2/3(15)

= -2(2x) - 2(5)

= -4x - 10

hence the equivalent expression is -4x - 10

Answer:

9.046 * 10^7

Step-by-step explanation:

90460000

We need one non-zero digit to the left of the decimal

9.0460000

We moved the decimal 7 places to the left so the exponent is 7

9.046 * 10^7

Answer:

9.046 × 10^7

Step-by-step explanation:

Move the decimal 7 times to the left. You come up with 9.046

Hope this helps :)

Answer:

1500%

Step-by-step explanation:

The formula for Percentage increase is

Increase/ Initial Amount × 100

Increase = Current Amount - Initial Amount

Increase = $320,000 - $20,000

Increase = $300,000

Percentage Increase =

$300,000/$20,000 × 100

= 1500%

The percent increase in home value in those 50 years is 1500%

Answer:

Number of quarts=16

Money earned=$32

Step-by-step explanation:

Given

4 Gallons of lemonade is prepared

They charge $2 for a quart

1 Gallon= 4 Quarts

Therefore Number of quarts

Therefore Number of quarts of lemonade prepared by them = 16 quarts

As they charge $2 for each quart

⇒

Total money made if they sell it all

Therefore, if they are to sell all the lemonade that they prepared

They would earn=$32

Answer:

hats = 5

mittens = 12

Step-by-step explanation:

hats = h

mittens = m

Uknown:

- How many hours per hats

- How many hours per mittens

Known:

- How many hours in total

- How many pairs of mittens made

- How many pairs of hats made

4h + 3m = 56

3h + 1m = 27

3h + m = 27

m = -3h + 27

4h + 3m = 56

4h + 3(-3h + 27) = 56

4h - 9h + 81 = 56

-5h = 56 - 81

-5h = -25

-5h/5 = -25/5

-h = -5

-h/-1 = -5/-1

h = 5

3h + m = 27

3(5) + m = 27

15 + m = 27

m = 27 - 15

m = 12

Check: h = 5, m = 12

4h + 3m = 56

3h + 1m = 27

4h + 3m = 56

4(5) + 3(12) = 56

20 + 36 = 56

56 = 56

3h + 1m = 27

3(5) + (12) = 27

15 + 12 = 27

27 = 27

Answer:

the difference in these two temperatures is 146.3°C

Step-by-step explanation:

The computation of the difference in these two temperatures is as follows:

= Highest temperature - lowest temperature

= 58.0°C - (-88.3°C)

= 58.0°C + 88.3°C

= 146.3°C

Hence, the difference in these two temperatures is 146.3°C

It is determined by the applying the above formula and the same is relevant
