Answer:

20:60 simplified

Step-by-step explanation:

so the question wants u to set up the ratio, Samantha's computer time to jacobs computer time, so 20:60 basically. now the choices they give u looks all simplified so we have to simplifi 20:60 witch is B)1 to 3. always remember when u r simplifing u have to divide the ratio by the same number.

Answer: y+4=-1/3(x)

Step-by-step explanation:

y-y1=m(x-x1) (Formula)

Y-intercept -4 so point is (0,-4)

m or slope=-1/3

y--4=-1/3(x-0)

y+4=-1/3(x)

Answer:

24, -5, -5, -40, -5

Step-by-step explanation:

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Answer:

12) 24

13) -5

14) -5

15) -40

16) 5

Step-by-step explanation:

Things to remember when you multiply/divide with negatives.

*Two negatives that are multiplied/divided are positive.

*A positive multiplied/divided by a negative turns negative.

*A negative multiplied/divided by a positive remains a negative.

Simplified version of the equations:

12) 6×4= 24

13) 20÷(-4)= -5 *The negative sign of the 4 turns the outcome into a negative.

14) -15÷3= -5

15) 5×(-8)= -40 *Don't forget the negative sign from the 8.

16) 10÷2= 5

You can also input these equations into a calculator.

Answer:

Supplement angle: 170°

Step-by-step explanation:

Equations

Let x=the required angle. Since complementary angles sum 90°, then 90-x is the complement of x. According to the conditions of the question:

[tex]90-x=40+4x[/tex]

Simplifying:

[tex]90-40=4x+x=5x[/tex]

Solving:

[tex]x=50/5=10[/tex]

The angle is 10°. The supplement angle is 180°-10°=170°.

Supplement angle: 170°

Your teacher didn't put any xy axis on this grid. But I'm assuming that the vectors are coming from the origin (0,0)

If that is the case, then vector v = (-2,4) and vector u = (2,1)

Add the corresponding coordinates to get

v+u = (-2,4)+(2,1) = (-2+2,1+4) = (0,5)

The general rule for adding vectors is

if u = (a,b) and v = (c,d), then u+v = (a+c, b+d)

Step-by-step explanation:

sum of three no =94

first no =X

second no x-8

third no =4(x-8)

X+(x-8)+4x-32=94

6x-40=94

6x=94-40

6x=54

X=54/6

X=9

Answer: The first number is 9, the second number is 17, and the third number is 68.

Step-by-step explanation:

Using the given information we will represent the first number by f , the second number by s, and the third number by t.

The first number is 8 less than the second  and we will represent that by the equation,   f= s-8

The third number is 4 times the second and it will be represented by the expression,  t= 4s  

We know the sum of the numbers has to equal  94 so we will add them.

The first number is s-8, the second is s, and the third is 4s.

(s - 8) + (s) + 4(s) = 94   Solve for s to find the second number.

6s - 8 = 94

    +8     +8

6s = 102    

s = 17  

The second number is 17 and we will input 17 in for s to solve for the first and third numbers.

f= 17 - 8

f= 9  

The first number is 11.

t= 4(17)

t = 68    

The third number is 68.

Check: Now add them to see if they equal to 94.

9+ 17 + 68 = 94

   94 = 94

Answer:

y=5/2 x

Step-by-step explanation:

The standard form of a linear equation is Ax +By=C

Answer:

Step-by-step explanation:

A car traveled at a constant speed as shown in the graph.

Distance traveled is on the y-axis and duration of travel on the x-axis.

Point A(3.5, 210) shows,

Distance traveled = 210 miles

Time to travel = 3.5 hours

So the point (3.5, 210) shows the distance traveled by the car in 3.5 hours is 210 miles.

Slope of the line = speed of the car = [tex]\frac{\text{Distance traveled}}{\text{Time}}[/tex]

                           = [tex]\frac{210}{3.5}[/tex]

                           = 60 mph

Now we will find the speed of the car at another point B(1, 60).

If the speed of car is same as the point B as of point A, point B will lie on the graph.

Speed of the car at B(1, 60) = [tex]\frac{\text{Distance traveled}}{\text{Time}}[/tex]

                                             = [tex]\frac{60}{1}[/tex]

                                             = 60 mph

Hence, we can say that point B(1, 60) lies on the graph.

Answer:

48 inches, 4 feet

Step-by-step explanation:

since each foot is 12 inches and we have 4 feet, we can multiply both numbers to convert 4 feet to inches. 12*4= 48 inches

to convert 48 inches to feet, we can divide by 12 since 12 inches is a foot. 48/12=4 feet

Answer:

0.8

Step-by-step explanation:

It is 0.8 because since you have y=1.8-0.2x (which is in the form of y=mx+b); and you have the value that x=5, all that you have to do is plug in 5 into the X in the equation.

Here is shown work:

y=1.8-0.2x

y=1.8-0.2(5)

y=1.8-1

y=0.8

Hopefully this helps! :)

The predicted depth value when the velocity value is 5 will be 0.8 feets

Given the regression model :

yˆ=1.8−0.2x

yˆ = Predicted value

x = velocity

To calculate the predicted depth, at a given velocity, x ;

Substitute the value of x and solve for yˆ in the equation

When x = 5

yˆ=1.8−0.2(5)

yˆ=1.8− 1.0

yˆ = 0.8

Therefore, the predicted depth value in feet is 0.8
