A person who weighs 164 pounds on Earth would weigh 80 pounds on a nearby planet.
If the weights are proportional, what would a person weighing 41 pounds on Earth weigh
on the nearby planet?
Answer:
84.05 lbs, I think...
Step-by-step explanation:
I divided 164 by 80 and got 2.05
Then I multiplied 2.04 by 41.......I might be wrong... But hopefully I'm not..
The weight of a person on the nearby planet will be 20 pounds.
What is proportion?A proportion is a comparison of two numbers that each represent the parts of a whole. A proportion says that two fractions are the same, even if the amount is different.
Given that, A person who weighs 164 pounds on Earth would weigh 80 pounds on a nearby planet, and the weights are proportional,
Since, the weights are proportional therefore,
Let the weight of a person on the nearby planet be x
Establishing the proportionality,
164/80 = 41/x
x = 80×41/164
x = 20
Hence, The weight of a person on the nearby planet will be 20 pounds.

The slope of a line is 2, and the y-intercept is 0. What is the equation of the line written in slope-intercept form?
Answer:
y=2x+0
Step-by-step explanation:
y=mx+b
y=(slope)x+(y-intercept)
y=2x+0
Answer:
y = 2x
Step-by-step explanation:
y = mx + b
m = slope

Three triangles are shown.
x represents the measure of an angle, y represents the measure of its supplement, and a and b represent the measures of the other 2 angles. Which of the following statements is true for all three triangles?
x>y because a+b>y
x is greater than y because A plus b is greater than y
y>x because 180−x>a+b
y is greater than x because 180 minus x is greater than A plus b
x=(a+b)−180
x is equal to open paren A plus b close paren minus 180
y=180−(a+b)

a second truck arrives whose ladder, when extended,is 30 meters long. the base of this ladder is also 4 metres above the ground. for safety reasons, the max angle of elevation that the ladder can make is 70%
Answer: The maximum height of the wall that can be reached by the ladder on the second truck = 58.19 meters
Step-by-step explanation:
A diagram for the given situation is attached.
To find: AC
In right triangle ABF,
[tex]\dfrac{AB}{AE}=\sin 70^{\circ}\\\\\Rightarrow\ \dfrac{AB}{30}=0.9397\\\\\Rightarrow\ AB=30\times0.9397\approx 28.19[/tex]
Now AC = AB + BC = 28.19 + 30 meters = 58.19 meters
Therefore, the maximum height of the wall that can be reached by the ladder on the second truck = 58.19 meters

Answer:
16.7
Step-by-step explanation:
The formula to find the area of a triangle is
[tex]a=\frac{base * height}{2}[/tex]
using this formula, plug in the area and the base
[tex]116.9=\frac{14b}{2}[/tex]
you can either multiply by 2 on both sides are divide 14b/2 which is 7b
116.9 *2 = 233.8
divide 233.8 by 14 to get 16.7
or divide 116.9 by 7 to get 6.7

Answer:
y=3x+0
Step-by-step explanation:
Answer:
y = 3x
Step-by-step explanation:
formula = y = mx + b
m = slope
b = y-intercept (but we dont see it here, it goes through the point 0)
To find slope do rise over run ( y/x)
r/r = 3/1 = 3
The slope is 3
y = 3x or y = 3x + 0 (same thing)

Jordan wants to buy a new car. He found a great car at a dealership for $18,000. The dealership offered him a compound interest rate of 3.5% for 60 months. How much will he be paying in interest only?
A-$3,150.00
B-$21,150.00
C-$3,378.35
D-$21,378.35
Answer:
$3,378.35
Step-by-step explanation
Before we can get the interest, we need to get the amount after 60 60months
A = P(1+r)^t
A = 18000(1+0.035)^5
A = 18000(1.035^5)
A = 18000(1.1877)
A = $21,378.35
Interest = Amount - Principal
Interest = 21,378.35- 18000
Interest = $3,378.35
Hence he will be paying $3,378.35 as interest

Do 1.7 and 1.700 have the same value? In a full sentence l, explain your answer why or why not
Answer: Yes ,because it isn't the same the number since the number of digits aren't the same so you make it the same number of digits by putting 0 in the back so 1.7 turns to 1.700 to make it the same digits of 1.700.
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
1.7 can equal 1.70 or 1.700000 or any number of zeros behind it because 0 does not add/change anything to the number other than its preciseness.

Lydia buys 3 apples and 2 pears from a fruit stand and spends $3.85. The next week she goes back and buys 4 apples and 1 pear and spends $3.80. Which system of equations can be used to find the cost per apple, a, and the cost per pear, p?
Answer:p=0.72 a=0.77
Step-by-step explanation:
By using system of equations we get cost per apple is 0.75 and cost per pear is 0.8.
What are System of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
By given data we construct system of equations
3a+2p=3.85...(1)
4a+p=3.80...(2)
We have to solve the above equations ,
Multiply with 2 in second equation.
8a+2p=7.6
So Now subtract from 1
3a+2p-8a-2p=3.85-7.6
3a-8a=-3.75
-5a=-3.75
a=3.75/5
a=0.75
Now substitute value of a in 3a+2p=3.85
3(0.75)+2p=3.85
2.25+2p=3.85
2p=1.6
p=0.8
Therefore cost per apple is 0.75 and cost per pear is 0.8.

Answer:
x=7
Step-by-step explanation:
I believe we are solving for x. In that case, let us start by moving 1 to the other side.
[tex]\frac{4(x+3)}{5} = 8[/tex]
Now, we want to get rid of that denominator of 5. Let us multiply both sides by 5:
[tex]4(x+3)=40[/tex]
Now, we may divide both sides by 4 to get rid of the coefficiant:
[tex]x+3=10[/tex]
When we subtract both sides by 3, we get
x=7
