Answer:
3/16
Step-by-step explanation:
All we have to do is multiply the top with the top and the bottom with the bottom:
15(1) = 15
20(4) = 80
15/80
We have our answer, but we can simplify it by dividing top and bottom by 5:
15/5 = 3
80/5 = 16
We have our final answer, 3/16.
Answer:3/16
Step-by-step explanation:15/20 x 1/4
The numerator (the upper number) would divide the denominator (the lower number) or the denominator would divide the numerator.
15/20 x 1/4
15 and 20 have something in common which is 5.so 5 in 15 is 3,5 in 20 is 4
15/20 x1/4
3/4 x 1/4
= 3/16

A = 5x · (3x + 7)
= 5x(3x) + 5x(7)
= 15x² + 35x meters
Answer:
15x^2+35x
Step-by-step explanation:
As the area formula is L*W, you're essentially doing the same thing here by multiplying both of these sides to get your area expression.
Take 5x and use the distributive property to multiply it with 3x+7 to get 15x^2+35x.
Shaun's dog weighs 22One-fourth pounds. The vet suggested that it would be a good idea for his dog to get more exercise, so Shaun walked her an extra mile every day. Shaun weighed the dog after one week and found she had lost Seven-eighths of a pound. How much does the dog weigh now?
Answer:
The weight of Shanu's dog now is 21.375 pounds.
Step-by-step explanation:
We are given that Shaun's dog weighs 22 One-fourth pounds. Shaun weighed the dog after one week and found she had lost Seven-eighths of a pound.
And we have to find the weight of the dog after exercise.
The Original weight of Shaun's dog = [tex]22 \frac{1}{4}\text{ pounds}[/tex]
Converting the above mixed fraction into an improper fraction we get;
[tex]22\frac{1}{4} = \frac{(22 \times 4)+1}{4}[/tex]
= [tex]\frac{89}{4} \text{ pounds}[/tex]
Now, it is stated that after walking an extra mile every day, Shanu's dog lost Seven-eighths of a pound, that is = [tex]\frac{7}{8} \text{ pound}[/tex]
So, the weight of Shanu's dog now = Original weight - Weight after exercise
= [tex]\frac{89}{4}-\frac{7}{8}[/tex]
Making denominator same for both the fractions;
= [tex]\frac{89\times 2}{4\times 2}-\frac{7\times 1}{8\times 1}[/tex]
= [tex]\frac{178}{8}-\frac{7}{8}[/tex]
= [tex]\frac{178-7}{8}[/tex]
= [tex]\frac{171}{8}[/tex] = 21.375 pounds.
Hence, the dog weigh 21.375 pounds now.
mr rai bys a radio for rs 1880ans sell it to mr Sherpa at 20 percent .how much money does he pay for it
Answer:
Rs 1504
Step-by-step explanation:
Mr. Rai buys for Rs 1880.
He sells it to Mr. Sherpa at 20% discount.
1880 × 20%
= 376
1880 - 376
= 1504
Mr. Sherpa buys it for Rs 1504.
Answer:
Mr. Rai will be receiving $1504 if he sells the radio for 20%.
Step-by-step explanation:
To find a discount, move the decimal over twice on the percentage. After doing this, multiply that number by the original number. You will get a new number. Subtract the price by the new number and there is your answer.
For Example:
20% = .20
1880*.20= 376
1880-376= 1504
There is a simpler way of doing this as well. Multiplying by .8 (which is the remainder of 100% after taking away 20% if this makes sense) will give you the answer immediately. Hopefully this helps.
Good luck!

Answer:
A. 162 m²
Step-by-step explanation:
==>Given:
Isosceles trapezoid with:
base a = 19m
base b = 35m
Perimeter = 74meters
==>Required:
Area of trapezoid
==>Solution:
Recall: the length of the legs of an isosceles trapezoid are equal.
Perimeter of isosceles trapezoid = sum of the parallel sides + 2(length of a leg of the trapezoid)
Let l = leg of trapezoid.
Perimeter = 74m
Sum of parallel sides = a+b = 19+35 = 54m
Thus,
74 = 54 + 2(l)
74 - 54 = 2(l)
20 = 2(l)
l = 20/2 = 10m
Let's find area:
Area = ½(a+b)*h
a = 19
b = 35
h = ?
Using Pythagorean theorem, let's find h as follows:
h² = l² - [(35-19)/2)²
h² = 10² - [16/2]²
h² = 100 - 64
h² = 36
h = √36 = 6m
Area = ½ x (a+b) × h
= ½ × (19+35) × 6
= ½ × 54 × 6
= 27 × 6
Area = 162m²

Find the values of the variables and the measures of the angles
Answer:
x = 13
39° and 51°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
This is a right angle triangle, so one side has a size of 90 degrees.
3x + 4x - 1 + 90 = 180
7x + 89 = 180
7x = 91
x = 91/7
x = 13
Put x as 13 to work out the size of the angles.
3(13) = 39
4(13) - 1
52 - 1 = 51
Answer:
[tex]x = 13 \\ [/tex]
Measure of the angles
[tex]39 \: \: degrees \\ 51 \: \: degrees[/tex]
Step-by-step explanation:
sum of the interior angles in a triangle= 180°
[tex]3x + 4x - 1 + 90 =1 80 \\ 7x + 89 =1 80 \\ 7x = 180 - 89 \\ 7x =9 1 \\ \frac{7x}{7} = \frac{91}{7} \\ x = 13[/tex]
x = 13,
now lets work out for the angles
[tex]3x \\ 3 \times 13 \\ = 39[/tex]
[tex]4x - 1 \\ 4 \times 13 - 1 \\ 52 - 1 \\ = 51[/tex]
Solve I=PRT for P if I=312.50, r=25%, and T=0.25
Answer: I = $ 19.53
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 25%/100 = 0.25 per year,
then, solving our equation
I = 312.5 × 0.25 × 0.25 = 19.53125
I = $ 19.53
The simple interest accumulated
on a principal of $ 312.50
at a rate of 25% per year
for 0.25 years is $ 19.53.
Answer:
P = 5000
You need to multiply r and T together, then divide 312.50 by that.

Answer:
[tex]Standard\ Form = {3n^2} m^{-2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3m^2n} * 4.5n^3[/tex]
Required
Write in Standard Form
To start with; the two monomials have to be multiplied together;
[tex]\frac{2}{3m^2n} * 4.5n^3[/tex]
[tex]Standard\ Form = \frac{2 * 4.5n^3}{3m^2n}[/tex]
Split the numerator and the denominator
[tex]Standard\ Form = \frac{2 * 4.5 * n^3}{3 * m^2 * n}[/tex]
Multiply Like terms
[tex]Standard\ Form = \frac{9 * n^3}{3 * m^2 * n}[/tex]
Divide 9 by 3 to give 3
[tex]Standard\ Form = \frac{3 * n^3}{m^2 * n}[/tex]
Divide n³ by n to n²
[tex]Standard\ Form = \frac{3 * n^2}{m^2 }[/tex]
Split fraction
[tex]Standard\ Form = {3 * n^2} * \frac{1}{m^2 }[/tex]
From laws of indices;
[tex]\frac{1}{a^n} = a^{-n}[/tex]
[tex]Standard\ Form = {3 * n^2} * \frac{1}{m^2 }[/tex] becomes
[tex]Standard\ Form = {3 * n^2} * m^{-2}[/tex]
Multiply all together
[tex]Standard\ Form = {3n^2} m^{-2}[/tex]
A $4'$ by $2'$ rectangular flag is made of a $2'$ by $2'$ black square bordered by a $1'$ by $2'$ white rectangle on each of two opposite sides of the black square. A white symbol covers one-third of the area of the black square. What fraction of the total area of the front of the flag is white? Express your answer as a common fraction.
=========================================================
Work Shown:
A = area of black square
A = 2*2
A = 4
B = area of white symbol
B = (1/3)*A
B = (1/3)*4
B = 4/3
C = total area
C = 4*2
C = 8
Divide the values of B and C to find the fraction of the total area the white symbol covers up.
B/C = (4/3)/8
B/C = (4/3) / (8/1)
B/C = (4/3) divided by (8/1)
B/C = (4/3) times (1/8)
B/C = (4*1)/(3*8)
B/C = 4/24
B/C = 1/6
A machine in a shoe factory produces shoelaces. The number of shoelaces it produces is proportional to the time. It car
produce twelve shoelaces in three minutes. Write an equation to represent this proportional relationship. In your
answer, make sure to define the variables you used.
Answer:
s = 4t
Step-by-step explanation:
Let number of shoelace produced be S and time taken to produce then be T
If the number of shoelaces it produces is proportional to the time, this can be expressed using a direct relationship as:
S∝T
S = kT where
k is the proportionality constant
If 12 laces of shoes can be produced in 3 minutes, then S = 12 and T = 3
The relationship above on substitution becomes
12 = 3k
k = 12/3
k = 4
If the proportionality constant is 4, then the equation representing the relationship will be:
s = 4t
please mark me brainliest!
Answer: y = 4x (y = shoelaces & x = minutes)
Step-by-step explanation: We know that 12 shoelaces are produced in 3 minutes and that the ratio of shoelaces produced to minutes spent is proportional. We can figure out, therefore, that if you multiply the number of minutes by 4, you will get the number of shoelaces. As an equation, this would be y = 4x (y = shoelaces & x = minutes).

Find the perimeter of the polygon with the vertices U(−2, 4), V(3, 4),U(−2, 4), V(3, 4), and W(3,−4)W(3,−4).
Answer:
Perimeter = 22.434
Step-by-step explanation:
To find the perimeter we need to find the length of all three sides, and we do that by finding the distance between the points that form the sides:
The formula for the distance between two points is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
side UV:
[tex]UV = \sqrt{(-2 - 3)^2 + (4 - 4)^2} = 5[/tex]
side VW:
[tex]VW = \sqrt{(3 - 3)^2 + (4 - (-4))^2} = 8[/tex]
side UW:
[tex]UW = \sqrt{(-2 - 3)^2 + (4 - (-4))^2} = 9.434[/tex]
So the perimeter is:
[tex]P = UV + VW + UW[/tex]
[tex]P = 5 + 8 + 9.434 = 22.434[/tex]

Answer:
a) 2.5x + 5 b) $5
Step-by-step explanation:
We know that the rate is 2.50 an hour, and she parked for 4 hours. Multiply 2.5 by 4 to get 10. This means that she spent 10 out of 15 of her dollars on the rate, meaning the initial fee was 5 dollars.
Answer:
a. y = 2.5x + 5
b. $5
Step-by-step explanation:
y = mx + b
m = slope is the fee per hour
b = y-intercept is the fixed fee
y = 2.5x + b
We know that she paid $15 for 4 hours, so we have point (4, 15). We now replace x and y in the equation with 4 and 15, respectively, and solve for b.
15 = 2.5(4) + b
15 = 10 + b
b = 5
a. The equation is:
y = 2.5x + 5
b. The initial fee is $5
