A bag contains 14 green tiles,10 red tiles, and 16 blue tiles. Brodie randomly draws a tiel, records the color , and replaces the tile.if he does this 80 times, how many times should he expect to draw a red tile
Answer:
20 red tiles
Step-by-step explanation:
14 green tiles,10 red tiles, and 16 blue tiles. = 40 tiles
P(red) = 10/40 = 1/4
If we draw 80 tiles
80 * 1/4 = 20
We should expect 20 red tiles

children visited the museum.
The number of children visited the museum on Tuesday will be 270.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Total number of people = 600
And, There are 45% were children.
Now,
Since, 45% were children.
Hence, The number of children = 45% of 600
= 45/100 × 600
= 45 × 6
= 270

G/2 + 7 = 21
Can I get help with this??
Answer:
g = 28
Step-by-step explanation:
g/2 + 7 = 21
Subtract 7 on both sides.
g/2 = 21-7
g/2 = 14
Multiply 2 on both sides.
g = 2(14)
g = 28
Answer:
g=28Solution,
[tex] \frac{g}{2} + 7 = 21 \\ or \: \frac{g + 7 \times 2}{2} = 21 \\ or \: \frac{g + 14}{2} = 21 \\ or \: g + 14 = 42(cross \: multiplication) \\ or \: g = 42 - 14 \\ g = 28[/tex]

find the coordinate of K' after a Glide reflection of the triangle: translation 4 units up and 4 units right then a reflection across the line y = 1.
Part 3a
Answer:
a. (-1, 3)
Step-by-step explanation:
The "glide" 4 units right and up is the transformation ...
(x, y) ⇒ (x+4, y+4)
The reflection across y=1 is the transformation ...
(x, y) ⇒ (x, 2-y)
Combined, you have the transformation ...

Solve the following equation:
2/3 - 1/x = 13/15
Answer:
x=−5
Step-by-step explanation:
Steps:
Step 1 to 4 : Simplify
Steps 5: Calculating the Least Common Multiple
Steps 6: Calculating Multipliers
The correct answer for this question is x=−5
Answer: x=−5
Hope this helps.
Answer:
x = -5
Step-by-step explanation:
2/3 - 1/x = 13/15
Subtract 2/3 from each side
2/3 -2/3 - 1/x = 13/15 -2/3
-1/x = 13/15 - 2/3
Getting a common denominator
-1/x = 13/15 -2/3*5/5
-1/x = 13/15 - 10/15
-1/x = 3/15
Using cross products
3x = -15
Divide each side by 3
3x/3 = -15/3
x = -5
Lucy’s parents built a swimming pool in the backyard. that the width is 18ft and the length is30ft , what's the disentrance around the pool , and what's the area of the pool , Use 3.14 for π.
Answer:
P=96;A=540
Step-by-step explanation:
To find the perimeter, the distance around the pool, all you need to do is add 18+18 then add 30+30. Why? Because assuming the pool is a rectangle, it would have 4 sides. The two width sizes as 18 and the two lengths as 30. Now, finding the area is even simpler. All you have to do is multiply the width by the length. 18*30.

A 13-foot board is cut into two pieces. The length of the shorter piece is 1 ft more than half the length of the longer piece. Find the length (in ft) of the shorter piece.
Answer: 1
Step-by-step explanation: 1
Length of the shorter piece of board is equals to 5foot.
What is length?
" Length is defined as the distance between two end points of any object."
According to the question,
Length of the board = 13foot
'l' represents the length of the longer piece
As per the condition given we have,
Length of the shorter piece = [tex]\frac{l}{2} +1[/tex]
Therefore,
[tex]l + \frac{l}{2}+1=13[/tex]
⇒ [tex]\frac{3l}{2} =13-1[/tex]
⇒[tex]l= \frac{2}{3} (12)[/tex]
⇒ [tex]l= 8foot[/tex]
Length of the shorter piece = [tex]\frac{8}{2} +1[/tex]
= [tex]5foot[/tex]
Hence, length of the shorter piece of board is equals to 5foot.

The Happy-Go-Lucky Beach was 163 feet long from parking lot to high tide. After last year's hurricane came ashore, the beach only measured 154 feet
long. What was the percent of change?
About 94.5% of increase
About 94.5 % of decrease
About 5.5% increase
About 5.5% decrease
Answer:
About 5.5% decrease
Step-by-step explanation:
Here, we want to calculate the percentage increase or decrease and its value.
The first thing to do here is to check if we are going to have a decrease or an increase.
since the value before the change is higher than the value after the change, then what we have is a decrease.
Mathematically, the percentage decrease is calculated as follows;
% decrease = (old value - new value)/old value * 100%
old value = 163 feet
new value = 154 feet
% decrease = (154-163)/163 * 100%
% decrease = -9/163 * 100%
% decrease = -5.52%
Thus the best answer is about 5.5% decrease

Answer:
see explanation
Step-by-step explanation:
(1)
Given
g(r) = (r + 14)² - 49
To obtain the zeros, let g(r) = 0 , that is
(r + 14)² - 49 = 0 ( add 49 to both sides )
(r + 14)² = 49 ( take the square root of both sides )
r + 14 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 14 from both sides )
r = - 14 ± 7, then
r = - 14 - 7 = - 21 ← smaller r
r = - 14 + 7 = - 7 ← larger r
(2)
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
g(r) = (r + 14)² - 49 ← is in vertex form
with vertex = (- 14, - 49 )

Find the volume of the pyramid. 100 points
120 yd^3
Step-by-step explanation:
The formula for the volume of a pyramid is...
[tex]V=\frac{1}{3}Bh[/tex]
B is the area of the base and h is the height from the middle of the pyramid to the top. Since we know both of these we can plug them in.
[tex]V=\frac{1}{3}(45*8)[/tex]
[tex]V=\frac{1}{3}*360[/tex]
[tex]V=[/tex]
120
The volume for the pyramid is 120 yd^3.
Answer:
120 yards ^3
Step-by-step explanation:
To solve we need to know the formula.
The formula for the volume of a pyramid is 1/3 B * H
B= 45 and H = 8. We can sub those values in to the formula to solve.
= 1/3 45*8
= 1/3 360
=120
Since we multiplied yd^2 by yd, we get yd^3
So the answer is 120 yd^3
