Answer:

4.) 7 : 4 = 36[g] : x [g]

    7 * x [g] = 4 * 36 [g]

    7 * x [g] = 144 [g]

    x [g] = 144 [g] / 7

    x [g]  ≈ 20, 57 [g]

5.) 3:2   250

3x + 2x =250

5x=250

x=50

3x=3*50=150

2x=2*50=100

The equation of the line CD is (y-3)=-2(x-4). what is the scope of the line perpendicular to line CD
Delicious77 [7]

Answer:

y=-1/2x-5

Step-by-step explanation:

First we need to put (y-3)=2(x-4) in slope intercept form.

we need to do order of operations....

so we need to first do the parenthesis

x*2= 2x

2*-4= -8

y-3=2x-8

add 3 on both sides to isolate y

y= 2x-5

so now we know the y=mx+b form

this is one line...

now we need to find out what line is perpendicular.

Perpendicular lines have opposite reciprocals slopes.

y=-1/2x-5

T. J. And Lindsey's lunch cost $30. They want to leave a 20% tip for their waiter. Use What is the amount of the tip that T.J. A
ahrayia [7]

Answer:

$6

Step-by-step explanation:

In order to find the amount of the tip that T.J. and Lindsey will leave for their waiter, you have to multiply the lunch cost for the percentage they want to leave as a tip for their waiter:

Lunch cost=$30

Percentage they want to leave as a tip= 20%

$30*20%=$6

According to this, the answer is that the amount of the tip is $6.

1.Write the slope-intercept form of the equation of the line that is parallel to AB and passes through Point X. Show all work fo
damaskus [11]
1. Start with y=sx+m and input the slope of the line given, because the two lines are parallel they have the same slope. Then input the X and Y coordinates of point X to get 10=-1/2-5+m and finally solve the equation to get m=-7.5 or -15/2 making slope intercept form Y=-1/2-5-15/2 
2. Follow the same instructions imputing 1/2 in as the slope because it is perpendicular to the line. so you get 10=1/2-5+m. solve to get m=7.5 or 15/2 making the final equation Y=1/2X+15/2

Write the expression in repeated multiplication form. Then write the expression as a power. (-8)^3*(-8)^4 The expression in repe
Makovka662 [10]

Given:

The expression is

(-8)^3\cdot (-8)^4

To find:

The expression in repeated multiplication form and then write the expression as a power.

Solution:

We have,

(-8)^3\cdot (-8)^4

The repeated multiplication form of this expression is

=[(-8)\cdot (-8)\cdot (-8)]\cdot [(-8)\cdot (-8)\cdot (-8)\cdot (-8)]

=(-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)

Clearly, (-8) is multiplied seven times by itself. So,

=(-8)^7

Therefore, the repeated multiplication form of the given expression is (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8) and the expression as single power is (-8)^7.
