4x+30

Step-by-step explanation:

Age of Adam=x Age of Beth= x+10 Age of Collin= 2(x+10)

Add like terms

x+(x+10)+2(x+10)= x+x+10+2x+20= 4x+30

Answer:

Im sorry if I'm wrong but I think it's 300+160=460

Answer:

yes your correct  but wrong

Step-by-step explanation:

To find  the area that's covered in corn you need to first write your fraction.

160/300

After you do that you have to turn it into a decimal.

.53333...

After that you need to turn it into a percent so your final answer will be....

53.333...%

BTW try looking to see if you need to round, normally it tells you to do that

Answer:

z=-13.9

Hope this helped!!

Answer: z= 4.1

Step-by-step explanation:

Answer:

Step-by-step explanation:

In order to find the answer. You first have to find the measure of the whole circle, which is 180.

Then you subtract 180-95 to find y.

180-95=85

So y=85

Then you subtract 180 from 80

180-80=100

So x=100

z=80

So the answer is D.

A two-sample  t -interval for a difference between population means

Step-by-step explanation:

i just took the test

The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means

Since the researcher selected a sample of 80 batters from summer baseball leagues and batters assigned to one of the two groups. So this means that the researcher is interested to know whether the mean no of hits should be different for two groups and both groups are independent to each other.

Therefore, The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means

Answer:

A = 45 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h( b₁ + b₂)

where h is the height and b₁, b₂ the parallel bases

Here h = 5, b₁ = 10 and b₂ = 8 , then

A = 0.5 × 5 × (10 + 8) = 0.5 × 5 × 18 = 45 cm²

Answer:

1545.66 rad/h

Step-by-step explanation:

We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.

We know that,

1 revolution = 2π rad

1 hour = 60 minute

So,

[tex]4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h[/tex]

So, the required angular velocity is 1545.66 rad/h.

Answer:-5+x<-1

Step-by-step explanation:

Answer:

H. -5 + x < -1

Step-by-step explanation:

Okay so let's first look at our little graph thing. What is it saying? It's telling us that what ever x is, it is NOT 4 (because the circle is not filled in) and it is less than 4 (because it's all shaded in before 4). Now that we know this, lets look at our possible answers.

F. x - 3 < 7

Now, for all of these possible answers, we can solve them exactly like normal equations (like x - 3 = 7).

x - 3 < 7

[add 3 to both sides to leave the x by itself]

x < 10

Whoa, that's not right! We don't even have 10 on our graph, so F is out of the running.

G. x + 6 [tex]\leq[/tex] 10

Okay, let's work smarter, not harder here. So we can see that there is a greater than or equal to sign there. So even if we solve it and we get 4 as the answer, our graph doesn't include 4. So we can throw this answer out right away.

H. -5 + x < -1

Solve like a normal equation in the first one.

-5 + x < -1

[add 5 to both sides to leave the x by itself]

x < 4

Hey! We got something! So let's read this with words. So whatever x is, it does not include 4, and is less than 4. So now looking back on our first brainstorm of the graph, this is in line with what we want.

So this is the answer! Yay!

Just for fun let's look at the last possible answer.

I. x - 8 > -4

Again, solve like a normal equation.

x - 8 > -4

[add 8 to both sides to leave x by itself]

x > 4

Oh! Another 4! But this time the sign is different. Let's read it again with words. So whatever x is, it does not include 4 (ok, good), and is greater than 4 (oh, not good). Our graph showed us that x is less than 4. So this answer is not the answer.

So again, we keep H. as our correct answer.

Answer:

Step-by-step explanation:

y=mx+b where m is the slope and b is the y intercept, value of y when x=0

11.

Since we are given the point (0,4) we already know that b=4

slope is m=(y2-y1)/(x2-x1), using our two points (0,4)(-1,3) we have

m=(3-4)/(-1-0)

m=-1/-1=1 so the line is

y=x+4

12.

Again they gave us point (0,1) so we know b=1, from points (0,1)(4,2) we find

m=(2-1)/(4-0)

m=1/4 so our line is

y=x/4+1 (or more neatly)

y=(x+4)/4

Answer:

b

Step-by-step explanation:

Answer:

1st Picture: d = -16

2nd Picture: g = -13.8

Step-by-step explanation:

1st Picture: Divide both sides by -11 to balance both sides and get the answer.

2nd Picture: Subtract 1.2 from both sides.

Answer:

Question 6:

We have -12.6 = g + 1.2, so we move the 1.2 to the left side to get -13.8 = g because when you move a number you are essentially minusing that number so 1.2 becomes -1.2 .

Question 7:

We have 176 = -11d so we divide by -11 to get -16 = d.
