Step-by-step explanation:  -49 -(-66)

= -49 + 66  ( here (-) and (-) is multiplied, therefore the final answer is +)

= 17                ( here when - and+ sign comes subtract them as we do normally, then mark the final answer with the greater number's sign, here the greater number is 66, so in the final answer we mark +17 or 17)

There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4. There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5. The two schools hold a dance and all students from both schools attend. What fraction of the students at the dance are girls?

Answers

Given:

Total number of students at Colfax Middle School = 270

Ratio of boys to girls is 5:4.

Total number of students at Winthrop Middle School = 180

Ratio of boys to girls is 4:5.

The two schools hold a dance and all students from both schools attend.

To find:

The fraction of the students at the dance are girls

Solution:

There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4.

[tex]5+4=9[/tex]

Number of boys [tex]=270\times \dfrac{5}{9}=150[/tex]

Number of girls [tex]=270\times \dfrac{4}{9}=120[/tex]

There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5.

[tex]4+5=9[/tex]

Number of boys [tex]=180\times \dfrac{4}{9}=80[/tex]

Number of girls [tex]=180\times \dfrac{5}{9}=100[/tex]

Now,

Total number of students in both schools [tex]= 270+180[/tex]

                                                                [tex]= 450[/tex]

Total number of girls in both schools [tex]= 120+100[/tex]

                                                         [tex]= 220[/tex]

The fraction of the students at the dance are girls is

[tex]\text{Required fraction}=\dfrac{\text{Total number of girls in both schools}}{\text{Total number of students in both schools}}[/tex]

[tex]\text{Required fraction}=\dfrac{220}{450}[/tex]

[tex]\text{Required fraction}=\dfrac{22}{45}[/tex]

Therefore, the required fraction is [tex]\dfrac{22}{45}[/tex].

Find the slope of each line (each block is one unit):

Answers

Answer:

1. 7

2. -3

4. -4/6

Step-by-step explanation:

i solved using y2-y1/x2-x1

Answer:

1. slope= 7

2. slope= -3

3. slope= -2/3

Step-by-step explanation

you find slope by doing rise over run (how much you have to go up/down and left/right to get to the next point.

for the first one, to get from the bottom point to the top point, you have to rise 7, and go to the right 1, which makes 7/1, simplified to 1.

for the second one, you go to rise 6, and then go to the left 2, which makes 6/-2, it is negative because when you have to go left, it just means a negative slope. this simplifies to -3

for the third one, you rise 4 and go to the left 6 from the bottom point to the top point. this makes 4/-6, simplifies to -2/3/

hope this help, i'm not the best explainer though, sorry :(

Answers

so like terms for example are 2x and 8x what makes them alike are their variable so if you have a term that is 2x and 7p those are NOT like terms because their variables are different
it’s basically asking you to put together the ones that have the same variable ! for example in #1 you have :
9d + 3y - 5g + 9g - 5 :

The only variable that is seen more than once is g. So you’d combine -5g + 9g

which would give you +4g, therefore:

#1. = 9d + 3y + 4g - 5

you could also use combine like terms calculator on wolframalpha.com, but I would suggest knowing what you’re doing so you can pass your tests!

The sets of numbers 3, 4, 5, and 8, 15, 17 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples!

Answers

Answer:

Pythagorean Theorom: a^2+b^2=c^2

Take the largest number of each as C (hypotenuse)

3,4,5

(3)^2+(4)^2= (5)^2

25=25

Therefore it is a Pythagorean Triple.

8,15,17

(8)^2+(15)^2=(17)^2

289=289

Therefore it is a Pythagorean Triple.

A cheetah runs with an average speed of 32 m/s for 30 seconds. How far did the cheetah run?

Answers

Answer:

o.2m.

s=av/t where av= average speed and s= speed and t= time

The cheetah ran 960 meters in 30 seconds with an average speed of

36 m/s.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

We know, distance = speed×time or d = st.

Given, A cheetah runs with an average speed of 32 m/s for 30 seconds.

Here, s = 32 m/s and t = 30 seconds.

Therefore, d = 32×30 meters.

d = 960 meters.

The function f(x)=0.39x+10.9 can be used to predict diamond production. For this​ function, x is the number of years after​ 2000, and​ f(x) is the value​ (in billions of​ dollars) of the​ year's diamond production. Use this function to predict diamond production in 2006 The diamond production in 2006 is predicted to be ​$[ ] nothing billion.

Answers

Answer:

The diamond production is 2006 is expected to be 13.24 billion

Step-by-step explanation:

Here, we want to predict the diamond production is 2006

The equation to use is given in the question as;

f(x) = 0.39x + 10.9

Since x is the number of years after 2006, in this particular question, x will be 2006-2000 = 6

So f(6) = 0.39(6) + 10.9

f(6) = 2.34 + 10.9

f(6) = 13.24 billion
