240/3= 80

80x8=640

Answer:

Ef=52

Step-by-step explanation:

By the mids segment theorem if a line sgement has endpoints on the midpoints of 2 sides of a triangle then it is half the size of the third side.

That means

2(4x+8)=9x-5

8x+16=9x+5

11=x

Then plug it back in to EF

4(11)+8

44+8

52

Answer:

You need to increase the amount of pizza sold by 24%, you can do it one of two ways:

236*0.24 = 56.64 and then do 236 + 56.64 = 292.64

(this way you find out what 24% of 236 is and then add it to 236 to get an increase of 24% )

or you can do this:

236 *1.24 = 292.64

(this way you're finding out what 124% of 236 is. I find this way easier because there's less steps. it works because you're still finding out what 24% is, you're just keeping the 236 there)

either way they need to sell 293 pizza's to get the prize

Answer:

2.7 < x 12.3

Step-by-step explanation:

using triangle inequality theorem:

(3 scenarios, discount the one that produce a negative)

4.8 + 7.5 > x        x < 12.3

4.8 + x > 7.5        x > 2.7

7.5 + x > 4.8    (discount)

Answer:

X-Intercept: [tex]x=-\frac{5}{2}y[/tex]

Y-Intercept: [tex]y=-\frac{2}{5}x[/tex]

Step-by-step explanation:

X-Intercept-

2x+5y=0     - Move the variable to the right-hand side and change its sign

2x=-5y     - Divide both side of the equation by 2

x=-5/27     - Write the solution x in parametric form

x=-5/2y, y∈R

Y-Intercept-

2x+5y=0    - Move the variable to the right hand side and change its sign

5y=-2x     Divide both sides of the equation by 5

y=-2/5x     Write the solution y in parametric form

y=-2/5x, x∈R

Answer: ↓↓

Step-by-step explanation:

∠ABF and m∠60° are complementary since they form a right angle.

∠ABF + 60 = 90

∠ABF = 30°

∠ABF and ∠CBD are vertical angles so they're congruent.

∠CBD ≅ ∠ABF

∠CBD ≅ 30

∠CBD = 30°

∠ABC and ∠CBD are linear pair so they're supplementary.

∠ABC + ∠CBD = 180°

∠ABC + 30 = 180

∠ABC = 150

It appears the only missing piece of the explanation is ...

  x² = 1225  ⇒  x = 35

Answer: Choice A.  [tex](-\infty, \infty)[/tex]

This is the same as saying the set of all real numbers.

There are no restrictions to put on the domain, so there are no values to avoid. This is because there are gaps, jumps, or holes in the graph. It's one continuous single curve.

This curve stretches forever to the left and right. As it goes left, it moves up (rises to the left). As it moves right, it goes downhill (it falls to the right). Saying "rises to the left and falls to the right" is an informal way to describe the end behavior. The actual specific end behavior doesn't matter. What matters is both left and right sides go on forever.

A domain of the set of all real numbers means we can plug in any real number for x, and get some output for y, which is part of the range.

One way we can describe the set of all real numbers in terms of an inequality is to write [tex]-\infty < x < \infty[/tex] meaning that x is between negative and positive infinity, ie x is anything you want. The inequality [tex]-\infty < x < \infty[/tex] converts to the interval notation [tex](-\infty, \infty)[/tex]. Interval notation is a compact way of writing compound inequalities.

Answer:

-1

Step-by-step explanation

Raising -1 to an odd power gives us -1, while raising -1 to an even power gives us (positive) 1. Because 2009 is odd, the answer is -1. The other answer choices are there to confuse you.

Answer:

The ordered pair will simply be the point at which these two lines cross. We solve the equations as simultaneous equations.

The solution is the point

(

−

6

,

−

11

)

Explanation:

We solve the set of two equations as simultaneous equations.

Call this Equation 1:

y

=

2

x

+

1

Call this Equation 2:

y

=

x

−

5

Rearrange Equation 2 to make

x

the subject:

x

=

y

+

5

Substitute this value of

x

into Equation 1:

y

=

(

y

Rearranging:

−

y

11

y

We can substitute this into either equation to find the value of

x

:

x

That means the intersection of the lines is at the point

Answer: See the attached image below

==============================================

Explanation:

The problem doesn't state this, but I'm assuming we have the same amount of each type of card. For instance, we could have 10 of each card.

The probability of getting any one type is 1/5 = 0.2 since there's one type we're after out of 5 shapes total. If we had 10 of each card, then the probability of getting a diamond is 10/50 = 1/5 = 0.2; note how there are 5*10 = 50 cards total.

If we expect 50 diamonds, then this must mean that 50/0.2 = 250 trials were conducted. You have the correct answer for the first box.

If we do 200 trials, then we expect (1/5)*200 = 40 cards would be a pentagon card. That explains row 2.

If we do 150 trials, then we expect (1/5)*150 = 30 star cards. The value 30 goes in the second box.

The value 300 goes in the third box. We find this by computing 60/0.2, or we can multiply 5 by 60. Note how (1/5)*300 = 60.

Lastly, if we conduct 50 trials, then we expect 10 circle cards because (1/5)*50 = 10.

Side note: the values 100 and 20 are not used.

Answer:

Surface currents probably

Step-by-step explanation:

Answer: 20%

Explanation:

1. Turn it into a fraction (224/280)

2. Divide the numerator (224) by the denominator (280). (224÷280=0.8)

3. Subtract 1 by 0.8 (or 100% by 80%) that should give you the answer 0.2 (20%)

Checking work:

280x0.2=56

280-56=224
