Step-by-step explanation:

6 + 8 = 14 which is bigger than 9 so it is possible

If the two shorter sides add up to a number that is equal to or smaller than the largest side, the triangle is impossible

Answer:

24, 21, 15, 12

Step-by-step explanation:

Since x is given in the table, you can find the y-values by plugging each of the x-value into the equation replacing x.

[tex]y=30-3(2)=30-6=24[/tex]  [tex](2, 24)[/tex]

[tex]y=30-3(3)=30-9=21[/tex]  [tex](3, 21)[/tex]

[tex]y=30-3(5)=30-15=15[/tex]  [tex](5, 15)[/tex]

[tex]y=30-3(6)=30-18=12[/tex]  [tex](6, 12)[/tex]

Step-by-step explanation:

It is convenient to let a spreadsheet or graphing calculator do the repetitive arithmetic.

__

If you want to do it by hand, put the x-value in the equation and do the arithmetic. For example, ...

  y = 30-3(2) = 30 -6 = 24 . . . for x=2

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

This a not so simple ratio problem:

     MN is to LN as TN is to UN as MT is to LU

     MN/LN    =   TN/UN    =   MT/ LU         trying to find LU

     88 / (? + 32)   =  (88-56)/32   = 56/?

                            =     32 / 32   = 56 / ?        

                                   1  =  56 / ?  

                                   ?  = 56  

     88 / (56 +32)  = 1      This must be an Isosceles triangle and UT bisects

                                       LN and MN

Answer:

C   m∠B = 48°

Step-by-step explanation:

The acute angles of a right triangle are complementary which means their sum is 90

m∠A + m∠B = 90

42 + m∠B = 90

m∠B = 48°

Answer:

Volume of box= Box Area * Box height

Step-by-step explanation:

If the box has equal sides then the l=w=h length is equal to height and both are equal to width so this can also be written as l=l=l or

Volume= length * width * height

V= l*w*h

V= l*l*l

V= l³

or  if the three sides are not equal this can also be written as

Volume of box= Box length * Box width * Box height

If we observe closely we find that length * breadth gives the area so the volume of the box can also be written as

Volume of box= Box length * Box width * Box height

Volume of box= Box Area * Box height

d is the answer

Step-by-step explanation:

the formula of finding a polygon's area is a=bh(1/2)

Example

on the chart it says base 4 and height 6 = an area of 12

which is saying 24 divided by 2 or 1/2 = 12

Answer:

The slope is 3.

Step-by-step explanation:

A direct variation function will always go through the origin point (0, 0).

Therefore, we have the two points (0, 0) and (-2, -6).

We can use the slope formula to find the slope:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute and evaluate:

[tex]\displaystyle m=\frac{0-(-6)}{0-(-2)}=\frac{6}{2}=3[/tex]

Therefore, the slope of the function is 3.

To graph, simply plot (0, 0) and (-2, -6) and draw a line connecting them. This is shown below.

Answer:

y = 2/3x - 3

Slope: 2/3x

Step-by-step explanation:

Slope: 2/3x

y- intercept: (0,-3)

once it goes down it'll be -2/-3x which will go to through (-2,-6) as soon as it goes down from the y-intercept.

equation: y = 2/3x - 3

Answer:

14 tons

$3,860.50

Step-by-step explanation:

Let x = the amount of sugar transported.

First company:

The cost is $3157 truck rental plus $50.25 per ton of sugar.

Total cost = 3157 + 50.25x dollars

Second company:

There is no charge for truck rental, but it costs $275.75 per ton of sugar.

The total cost is

275.75x

When the two costs are the same, then

275.75x = 3157 +50.25x

225.5x = 3157

x = 14 tons

The total cost is 275.75*14 = $3,860.50

Answer:

  (b)  10,000π ft³

Step-by-step explanation:

The relation between circumference and radius is ...

  C = 2πr

  r = C/(2π) = (20π)/(2π) = 10 . . . . feet

The volume of a cylinder with radius 10 ft and height 100 ft is ...

  V = πr²h

  V = π(10 ft)²(100 ft)

  V = 10,000π ft³

Answer:

10,000π ft3

Step-by-step explanation:

Use this formula :

[tex] = \pi \times {r}^{2 } \times t[/tex]

[tex] = \frac{22}{7} \times {( \frac{14}{2} )}^{2} \times 10 \\ [/tex]

[tex] = \frac{22}{7} \times {7}^{2} \times 10 \\ [/tex]

[tex] = \frac{22}{ \cancel7} \times \cancel{49} \times 10 \\ [/tex]

Answer:

9. C. 35 + 0.12x = 44.36

10. C. The system has no solution since the second equation is equal to 0

11. A. 32

Step-by-step explanation:

9. The Hill family drove for 78 miles

The rental agency chargers a weekend fee of $35.00 and 12 cents per mile

Convert cents to dollars

1 cent = 0.01 dollar  

∴, 12 cent = 12 x 0.01 = 0.12 dollar

Therefore,  total bill amount = 35 + 0.12 per mile

Let "x" be the number of miles driven

Final bill was $ 44.36

44.36 = 35 + 0.12x  

0.12x = 44.36 - 35  

0.12x = 9.36

Divide both sides of the equation by 0.12

x = 78

10. The system of equations is...

The true statement about the given system of equations.  

The slope-intercept form of a line is...

Where m is the slope and b is the y-intercept.

We have,...  

On comparing these two lines with slope-intercept form, we get...  

Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.

11. This is an equation Solutions: x=32.

⇒ Value of (Dimes + Quarters) = $ 6.70  

or, (0.1 m) +  11.5 - 0.25 m  = 6.70  

-0.15 m = - 4.8  

or, m = 4.8/0.15  =  32  

⇒ m = 32
