The base of an isosceles triangle is 30” and the altitude to that base is 8”. Find the length of one of
the two equal sides of the triangle.
please help!
Answer:
17"
Step-by-step explanation:
Isosceles means there are two equal sides in this triangle.
So the height not only is perpendicular to the base, but also cuts the base in half.
Each half is 15 inches. (30÷2=15) See image.
These half triangles formed by the height, are right triangles. You can use Pythagorean theorem or if you're familiar with the pythagorean triple 8, 15, 17, you will find the length of the side is 17 inches. See image.

what percent is 700 paise of 7 rupees
To find :-
What percent is 700 paise of 7 rupees .Solution :-
As we know that,
→ ₹1 = 100 p
So ,
→ 700p = ₹ 700/100
→ 700p = ₹ 7
Now let's calculate % , as ;
→ 700p / ₹7 * 100 %
→ ₹7/₹7 *100 %
→ 1 *100%
→ 100%
Hence 700p is 100% of ₹7 .
I hope this helps.
Step-by-step explanation:
We know that ,
1rupees = 100 paise
so , 7 rupees = 700 paise
We have to find the percentage of 700 paise of 7 rupees
Calculating Percentage ,
700paise/7rupees×100

What is the percent of change from 5 to 8?
Answer:
60%
Step-by-step explanation:
5-8/5 * 100%= 60%
The percentage change from 5 to 8 is given by A = 60 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage change be represented as A
Now , the equation will be
Let the first number be p = 5
Let the second number be q = 8
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
On simplifying the equation , we get
Percentage change A = [ ( 8 - 5 ) / 5 ] x 100
Percentage change A = ( 3/5 ) x 100
Percentage change A = 60 %
Hence , the percentage change is 60 %

Answer:
55w + 145
Step-by-step explanation:
Total = all accounts, so you have to add 10w to 45w, and 120 to 25
10w + 45w = 55w
120 + 25 = 145
So the answer is 55w + 145
10. 8 fewer than the sum of 14 and a number
Answer:
6 +x
Step-by-step explanation:
Let the number = x
Sum of 14 and a number = 14 +x
8 fewer than (14 + x )= 14 + x - 8 = 6 +x
Answer: 14 + x - 8 (can also be 6 + x)
Step-by-step explanation:
8 fewer means we're subtracting 8, which is -8
Sum of 14 and a number would be 14 + x
All of this combined would be 14 + x - 8 but if you want to simplify it, you can subtract 8 from 14 and get 6. This would be 6 + x.

The cost of a sweatshirt is 175% the cost of a T-shirt. A T-shirt costs $13.
What is the cost of 3 sweatshirts?
Enter your answer in the box.
Answer:A standard blank t shirt will usually start at around $1 each and go up to $4. These are going to be cotton, good quality shirts. The price difference will vary on manufacturer, brand, color and cut. So a plain white t shirt might only be $1, where the same shirt in navy blue might be $2.
Step-by-step explanation:
If you want a profit of 50% off the retail price, the calculation is straightforward. Let's say the production cost of your t-shirt amount to ₹300. When you multiply it by two, you get ₹600. And that would be the retail price of each t-shirt piece

Benita buys 2 shirts for the same price s the taxe sale rate is 6.5%
Answer:
2s + 0.13s
2.13s
Step-by-step explanation:
One shirt costs s.
2 shirts cost 2s.
The tax rate is 6.5%, so the tax on 2s is 0.065 × 2s = 0.13s
The total cost with tax is 2s + 0.13s
You can also find the total cost by realizing that since the tax is 6.5%, the total price with tax is 1.065 times the cost, so you can write it as 1.065 × 2s = 2.13s
Answer:
2s + 0.13s
2.13s
Answer:
2.13s
and
2s+0.13s
Step-by-step explanation:
Because 2 shirts is s and 6.5 per cent would turn into 6.5 because of 2 times 1.065 is 0.13 which is the answer for part 2

what is 3 times 34 divided by 2 plus 8 times 5
Answer: 91
Step-by-step explanation: 3 times 34 is equal to 102... let us work out the problem together.
3 x 34 = 102
now we must divided 102 by 2 which will equal 51
Now the final step is to do 8 times 5
8 times 5 = 40
51 plus 40 = 91
this is the correct way to do the equation.

Write the equation of a line parallel to the line y = 3x+5 and passes through the point (-7, 2)
Answer:
y=3x+23
Step-by-step explanation:
Parallel lines have the same slope, so we basically keep the same equation, but we find the new y-intercept so it accounts for (-7,2):
y = 3x + b
2 = 3(-7) + b
2 = -21 + b
23 = b
Therefore, your equation would be y=3x+23
Darlene is making a quilt that has alternating stripes of regular quilting fabric and sateen fabric. She spends $76 on a total of 16 yards of the two fabrics at a fabric store. Sateen fabric costs $6 per yard and quilting fabric costs $4 per yard. Which system of equations can be used to find the amount x (in yards) of regular quilting fabric and the amount y (in yards) of sateen fabric she purchased?
Answer:
[tex]\left \{ {{6x+4y=76} \atop {x+y=16}} \right.[/tex]
Step-by-step explanation:
1) if (according to the condition) the amount of quilting is 'x' and the amount of sateen is 'y', then the price of the quilting fabric is 6*x and the price of then sateen fabric is 4*y;
2) the 76$ she spends can be written as 6x+4y=76;
3) total of 16 yards can be written as x+y=16;
4) finally, the required system is:
[tex]\left \{ {{6x+4y=76} \atop {x+y=16}} \right.[/tex]
A system of equations is a collection of two or more equations with a same set of unknowns. 4x+6y=76, x+y=16 are required system of equations.
What is system of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
