A nan brought a cow for $200 and sold it to gain $50. What was his gain as a percentage of the cost price?
Answers
Answer:
25%
Step-by-step explanation:
Given that,
The cost price of a cow, CP = $200
Gain = $50
We need to find the gain percentage of the cost price.
SP = CP + gain
= 50 + 200
= $250
[tex]\text{Gain}\%=\dfrac{\text{Gain}}{CP}\times 100\\\\=\dfrac{50}{200}\times 100\\\\=25\%[/tex]
So, the gain percent is 25%.

Identify the slope and y-intercept for the linear equation below.
y = 1/3x+7
Answers
Answer:
Slope is 1/3.
Y-intercept is 7.
Step-by-step explanation:
y = mx + b is the slope-intercept form.
m = slope
b = y-intercept
In the equation, y = 1/3x + 7
m = 1/3
b = 7
Therefore, slope is 1/3 and y-intercept is 7.
Hope this helped! <3
Answer:
Slope is 1/3 and the y- intercept is 7
Step-by-step explanation:
Since the equation is y = mx+b, we know that 1/3 is the slope since m represents the slope and b represent the y-intercept, meaning 7 is the answer.

PLEASE HELP!! WHAT IS x???
Answers
9514 1404 393
Answer:
x = 90 degrees
Step-by-step explanation:
There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.
arc DE = 2×∠DFE = 60°
arc EF = 2×∠ECF = 60°
arc CF = 2×∠CEF = 60°
Then arc DEC is ...
arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°
Angle DBC is half the measure of this arc, so is ...
∠DBC = 180°/2 = 90° = x

Answers
9514 1404 393
Answer:
length: 50 ydwidth: 40 ydStep-by-step explanation:
The perimeter is twice the sum of length and width. Then the sum of length and width is 90 yards. Their product is the area, so we have ...
x(90 -x) = 2000 . . . . where x is length or width
x^2 -90x +2000 = 0 . . . . rearrange to standard form
(x -40)(x -50) = 0 . . . . . . . factor
x = 40 or x = 50
The dimensions of the rectangular plot are 40 yards by 50 yards.
If a person weighs 130 Ibs and they lose 1/10 of their weight.How much weight was lost
Answers
Answer:
13 lbs
Step-by-step explanation:
to find 1/10 we divide by 10
This can be found by moving the decimal back by one
So 130/10=13
13 lbs were lost
The person lost 13 lbs of weight.
What is weight?
Weight is the measure of how heavy an object is. Weight is measured in standard customary units. The mass of an object is the amount of material it contains.
Given that, the person weight=130 lbs and he lost 1/10 of his weight.
We need to find how much weight was lost.
Now, weight lost [tex]=\frac{1}{10} \times 130=13[/tex] lbs.
Hence, the person lost 13 lbs of weight.

Once you’ve done this you can see that the two expressions are actually the same and therefore equal to each other.
The best description of the equivalency would be D
Just because the sum of the constants are equal doesn’t mean the expressions are. There could be different amounts of the variable (that’s why you should always simplify )

Answer:
Answer:
1). Option (A)
2). Option (A)
Step-by-step explanation:
1). A worker bee has the mass = 0.00011 kg
In scientific notation we can convert the mass of bee as,
0.00011 =
=
Since 1.1 ≈ 1,
Therefore, 1.1 × 10⁻⁴ ≈ 1 × 10⁻⁴ kg
Option (A) is the answer.
2). An African elephant has a mass = 8139 kg
In scientific notation,
8139 = 8.139 × 10³
Since, 8.139 ≈ 8
Therefore, 8139 kg = 8.139 × 10³ kg
Option (A) is the answer.
