Which number is the largest?
1.2 × 104, 4.5 × 10−3, 3.8 × 103, 7.5 × 103
Answer:
1.2 x 10^4 = 12,000
4.5 x 10^-3 = 4.5 x 1/(10^3) = 4.5/1000 = 0.0045
3.8 x 10^3 = 3,000
7.5 x 10^3 = 7,000

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!
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.
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?
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].

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.
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

Answer:
∠ 1 = 149°, ∠ 2 = 31°
Step-by-step explanation:
∠ 1 and 31° are same-side interior angles and are supplementary, thus
∠ 1 = 180° - 31° = 149°
∠ 2 and 31° are alternate angles and congruent, thus
∠ 2 = 31°

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

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