Answer:
-1.25 or -10/8
Step-by-step explanation:
the additive inverse of a number is the number that would make it zero when added
ex. the inverse of 5 is -5 because 5+(-5)=0
so the inverse of -5/8 is 5/8 because -5/8+5/8=0. The question said to subtract the additive inverse.
-5/8-(5/8)=
-5/8-5/8=
-10/8 or -1.25

The marked price of a watch is 30% above the cost price. When it is sold allowing 20% discount on it, there is a gain of Rs 150. Find the marked price and the cost price of them.
Answer:
Marked price: Rs. 4875
Cost price: Rs. 3750
Explanation:
(i) Cost price: 100%
(ii) Marked price: (100% + 30%) = 130%
(i) Let the cost price be p
(ii) Marked price: 130% × p = 1.3p
Given, 20% discount then sold at 80%
Discount price: (130% × 80%) × p = 1.04p - discounted price
Gain price: 1.04p - p = 0.04p
Cost price:
0.04p = 150
p = 150/0.04 = 3750 ← This is the cost price.
Marked price:
1.3p = 1.3(3750) = Rs. 4875
The ratio of adults to children at a party is 3:5
What fraction of the party are adults?
There are 72 people at the party.
Work out the number of children at the party.
The ratio of adults to children at a party is 3:5. There are 72 people at the party. Find out number of children.
✭ Explanation -:In this question we are provided with the ratio of adult and children 3 : 5 respectively. It is given that 72 people are there at the party. We are asked to calculate number of children.
We are asked to calculate number of children
Let us assume number of adults and children as 3x and 5x
It is given that total number of people are 72.
According To Question
3x + 5x = 72
→ 8x = 72
→ x = 72/8 = 9
x = 9
Adults = 3x = 3 × 9 = 27 people
Children = 5x = 5 × 9 = 45 people
Hence, there are 45 children in the party.Aisha has a piece of string that she cuts into smaller pieces. This line plot shows the length of each piece. Juan has a piece of string that is 12 as long as Aisha's seventh-longest piece. (Note: The problem states the seventh-longest piece, not the seventh-longest length.)
How long is Juan's piece of string?
Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
2 5/8 inches
Step-by-step explanation:
There are 2 pieces 5 3/4 inches long.
There is 1 piece 5 1/2 inches long.
There are 4 pieces 5 1/4 inches long.
The seventh longest piece is one of the pieces measuring 5 1/4 inches.
Juan's piece is 1/2 as long as 5 1/4 inches.
1/2 × 5 1/4 inches = 1/2 × 21/4 = 21/8 inches = (16/8 + 5/8) = 2 5/8 inches

Step-by-step explanation:
rhombuses have all equal sides, 2 sets of parallel lines and are a diamond shape. a quadrilateral is a shape with 4 sides (quad means 4) therefore, all rhombuses are parallelograms. we know that all trapezoids have 4 sides, so we can conclude that all trapezoids are quadrilaterals i hope this helped because i know that end of year tests are super hard.
If you roll a standard number cube 95 times, how many times do you expect the cube to show a one or a three?
Answer:
32 times
Step-by-step explanation:
the probability in getting a certain number is you first find out the chance of rolling one side on a die. There are six sides, and there is two numbers on it you want a 3 and a 1. so you would get 2/6 would be the fraction of what you what most likely get, so you would multiply 95 by 2/6 you get the correct answer
if the sine ratio is given, then how can sin 0/2 be determined?
Step-by-step explanation:
If you know, the sine. You must find the cos ratio, using the Pythagorean trig theorem.
Next, you use the half angle identity for sin
[tex] \sin( \frac{ \alpha }{2} ) = \sqrt{ \frac{1 - \cos(a) }{2} } [/tex]
Example.
[tex] \sin( \alpha ) = \frac{ \sqrt{3} }{2} [/tex]
We must find
[tex] \sin( \frac{ \alpha }{2} ) [/tex]
First, use the Pythagorean identity
[tex] \sin {}^{2} ( \alpha ) + \cos {}^{2} ( \alpha ) = 1[/tex]
[tex]( \frac{ \sqrt{3} }{2} ) {}^{2} + \cos {}^{2} (a) = 1[/tex]
[tex] \frac{3}{4} + \cos {}^{2} (a) = 1[/tex]
[tex] \cos {}^{2} (a) = \frac{1}{4} [/tex]
[tex] \cos( \alpha ) = \frac{1}{2} [/tex]
Now use the half angle identiy
[tex] \sin( \frac{ \alpha }{2} ) = \sqrt{ \frac{1 - \cos( \alpha ) }{2} } [/tex]
[tex] = \frac{ \sqrt{1 - \frac{1}{2} } }{ \sqrt{2} } [/tex]
[tex] = \frac{ \sqrt{ \frac{1}{2} } }{ \sqrt{2} } [/tex]
[tex] = \frac{ \sqrt{ \frac{1}{2} } }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{ \sqrt{1} }{ \sqrt{4} } = \frac{1}{2} [/tex]
So the answer for our example is 1/2
The lengths of two sides of a triangle are 5 inches and 8 inches. Which of the following lengths could be the length of the third side of the triangle? Select all that apply.
By using the triangular inequality, we conclude that the other side must measure more than 3 inches and less than 13 inches.
Which values could the length of the third side take?
Remember that the triangular inequality says that the sum of any two sides on a triangle is larger than the other side of the triangle.
If we define the missing side of the triangle as x, then we must have:
5 + x > 8
8 + x > 5
8 + 5 > x
From the third inequality we get the upper bound:
13 > x.
From the first inequality we get the lower bound:
x > 8 - 5 = 3
Then:
3 < x < 13
This means that the other side of the triangle must measure more than 3 inches and less than 13 inches.

Notice that we are asked to use 3.142 for [tex]\pi[/tex] (pi).

To find the radius, we divide the diameter by 2.
