Step-by-step explanation:
let the percent of found balloons be x
given,
total number of balloons= 70
number of found balloons= 28
according to the question,
x% of 70= 28
x/100 × 70 = 28
x=40
hence 40% of the balloons were found

Which input value produces the same output value for the two functions on the graph
X = 1
Because where the two lines intersect, they have the same x value, one
Answer:
x = 1
Step-by-step explanation:
Look at the graph to see where the lines intersect.
f(1) = 1
g(1) = 1
When x = 1, the output value of both functions is 1.

circlecenterradiuschorddiametersecant=======================================
Explanations:
Consider a campfire and people surrounding it to warm up. The fire itself is the center of the circle, and the people around it are points on the circle's edge. Assume that each person is the same distance away from the fire. Refer to the diagram below.We always refer to the circle name by the center point. Think of it being like at the center of the universe, or you could think how the sun is at the center of the solar system. While technically the planets orbit in ellipses and not perfect circles, this idea still could be useful to help remember the naming convention. If we go back to the example in part 1, the radius is the distance from the campfire to any given person. The radius is half the diameter. This is not to be confused with the spelling "cord" which refers to wiring used in electronics, or in fabric fibers. If we connected any two campers with a segment, then we formed a chord. Refer back to part 1 above. Any diameter is a chord, but not the other way around.The diameter is a special type of chord that goes through the center. Note the endpoints of the diameter are on the circle's edge. A secant line is basically a chord but we've extended both endpoints off infinitely in both directions. A secant cuts the circle at 2 different points. In contrast, a tangent line touches the circle at exactly one point only.which expressions have value between 1 and 2? choose all that apply.

Perimeter = 22 cmPerimeter = 22 cmPerimeter = 30 cm==============================================
Explanation:
The perimeter is the total distance around the outer edge of the figure. It's the total amount of fence you need to enclose the region.
So we simply add up all the side lengths. Refer to the diagram to see any missing sides that aren't labeled (shown in blue).
For instance, the perimeter for problem 1 is 5+2+2.5+4+2.5+6 = 22 cm. Problems 2 and 3 are handled the same way.
It's not a typo that the perimeters of problems 1 and 2 are the same value. This is because both figures can be surrounded by a rectangle that is 6 cm across and 5 cm tall. The perimeter of the surrounding rectangle is exactly the same as the perimeter of the inner fenced region. We're effectively just moving fence around but not changing the perimeter.
A gum ball machine has 6 red gum balls, 3 green gum balls, and 5 blue gum balls. What is the probability that the next gum ball that comes out will be red?
Answer:
Step-by-step explanation:
P(red gum ball)= 6/14=3/7
6/14 can be simplified to 3/7 by dividing by 2. 6/2=3. 14/2=7.

Answer:
[tex] \displaystyle x = 15[/tex]
Step-by-step explanation:
by triangle midsegment theorem we obtain:
[tex] \displaystyle \frac{10x + 44}{2} = 8x - 23[/tex]
simplify division:
[tex] \displaystyle 5x + 22 = 8x - 23[/tex]
move 5x to right hand side and -23 to the left hand side and change its sign:
[tex] \displaystyle 22 + 23= 8x - 5x[/tex]
simplify addition:
[tex] \displaystyle 8x - 5x = 45[/tex]
collect like terms:
[tex] \displaystyle 3x = 45[/tex]
divide both sides by 3:
[tex] \displaystyle x = 15[/tex]
and we are done!

5. The property depicted in the expression 2/( 3) ×(1/3+ 4/5)=(2/3 × 1/3)+(2/3 × 4/5) is *
associative property of addition
associative property of multiplication
distributive property of multiplication
closure property of multiplication
Answer:
distributive property of multiplication over addition
Step-by-step explanation:
a(b + c) = ab + ac
The a to the left of the parentheses multiplies both numbers inside the parentheses. The you add the products.
This is the distributive property of multiplication over addition.
2/3 × (1/3 + 4/5) = (2/3 × 1/3) + (2/3 × 4/5)
The 2/3 to the left of the parentheses multiplies both numbers inside the parentheses. The you add the products.
This is the distributive property of multiplication over addition.

I don't know Spanish/what laugnange you speak sorry.
what is b
−2.9+ b/0.1 = − 39.9
Answer:
b = - 1.09
Step-by-step explanation:
- 2.9 + b ÷ 0.1 = - 39.9
- 2.9 + b ÷ 0.1 × 0.1 = - 39.9 × 0.1
- 2.9 + b = - 3.99
- 2.9 + 2.9 + b = - 3.99 + 2.9
b = - 1.09
Answer:
Exact form
b=-37/10
Decimal form
b=-3.7
Mixed Number form
b+-3 7/10
Step-by-step explanation:
-2.9+b/1/10+-39.9
-2.9+10b+-39.9
10b=-39.9+2.9
10b=-37
b=-37/10

Ron invested $700 for 9 years at 3.4% compounded semi-annually. How many compounding periods are there over the term of the investment?
Answer:
financial equations use the formula
[tex]A=P (1 + \frac{r}n)} ^{nt}[/tex]
where
A is accrued amount
P = principal
r= interest rate
t = number of periods (NOTE: NOT NUMBER OF YEARS !!!)
r = interest rate (NOTE: APR the whole years interest NOT the period)
So in your question the compounding is being done "Semi-annually:
NOTE:
Annual = 1
semi-annual = 2
Quarterly = 4
monthly = 12
So your number of periods is ..... number of years (9) times the number of periods in a year (2 - for semi-annual)
9 * 2 = 18 there are 18 periods
[tex]A=P (1 + \frac{.034}2)} ^{18}[/tex]

The length of a box is 6 inches, the width is 4 inches and the height is 2/8 inches. What is the volume of the box?
Answer:
6 cubic inches
Step-by-step explanation:
To find the volume of a box you do Length * Width * Height
So we can do:
6*4*2/8
=24*2/8
=6
The volume of the box is 6 cubic inches
Dada a função fx=0,15.X+900 , determine a) f(80) b) f(120) c) f(200) d) f(56)
Answer:
See answers below
Step-by-step explanation:
Given the function:
f(x) = 0.15x + 900
a) f(80) = 0.15(80) + 900
f(80) = 12 + 900
f(80) = 912
b) f(120) = 0.15(120) + 900
f(120) = 18 + 900
f(120) = 918
c) f(200) = 0.15(200) + 900
f(200) = 30 + 900
f(200) = 930
d) f(56) = 0.15(56) + 900
f(56) = 8.4 + 900
f(56) = 908.4
The width of Field A is 7/12 of its length of 108 m. What is the perimeter of Field B if it has 5/6 of the perimeter of Field A?
Answer: (100th answer)
perimeter of field b = 260 m
Step-by-step explanation:
First we have to find what is 7/12 of 108?
Well first we need to know what 1/12 of 108 is. Which means we do 108/12. That equals 9. so if 1/12 of 108 = 9
then 7/12 of 108 is 9*7 which is 63.
The width of field A is 63 plus its length, width again and its length again would be its perimeter or
2l + 2w is its perimeter, where l is length and w is width
108*2+63*2= perimeter
216+126 = ?
342 is the perimeter of field A.
We aren't done though.
We have to find 5/6 of 342.
1/6 of 342 is 342/6
342/6 = 52
1/6 of 342 = 52 meaning 5/6 of 342 is equal to 5*52.
5*52 = 260
the perimeter of field b is 260
1. Find the value of x to the nearest tenth
A. 19.2
B. 20.8
C. 21.3
D. 19.7
Answer:
20.8
Step-by-step explanation:
Use the Pythagoras's Theorem
12²-36²=[tex]\frac{x}{2}[/tex]²
144-36=[tex]\frac{x}{2}[/tex]²
108=[tex]\frac{x}{2}[/tex]²
Root both sides
√108=√[tex]\frac{x}{2}[/tex]²
[tex]\frac{x}{2}[/tex]≈10.4
[tex]\frac{x}{2}[/tex]·2=10.4·2
x=20.8
