Answer:
14 windows is the answer
Step-by-step explanation:
windows washed before lunch = 1/3 of total windows
= 1/3 * 33
= 11 windows
windows washed after lunch = 8
windows remaining = total - washed before lunch - washed after lunch
remaining = 33 - 11 - 8
= 33 - 19
= 14 windows

There are a total of 14 marbles in the bag, with only 3 being red. 3/14 converts to 0.214
how would i solve this with a graph AND A FUNCTION TABLE?!?!?!?!?
y=-1/4x - 3
did I choose the right graph?
Answer:
Step-by-step explanation:
The - tells you that it is upside down. So that much of your choice is correct for certain.
The 1/8 squishes the graph something fierce. So of those graphs given, the one you chose is most likely correct. But you are right to be a little miffed at the question. You should never have to choose an answer with only a picture to guide you. If you have a graphing calculator, try y = -1/8 x^2 which is a good candidate for all the graphs.

the mean of three number is 15. if 2 of the numbers are 18 and 16 what is the third number
Answer:
11
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let the third number be x , then
[tex]\frac{18+16+x}{3}[/tex] = 15 ( multiply both sides by 3 to clear the fraction )
34 + x = 45 ( subtract 34 from both sides )
x = 11 ← third number

Answer:
1583.4 ft³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
The radius is half the diameter, so is (12 ft)/2 = 6 ft. Then the volume is ...
V = π(6 ft)²(14 ft) ≈ 1583.4 ft³
_____
Additional comment
The number shown in the problem statement answer box is the number you would get using the diameter in the above formula instead of the radius.
The volume of cylinder is 1583.4ft³.
Step-by-step explanation:
Given that :-
Height of cylinder = 14 ftBase diameter if cylinder = 12 ft
so, Radius of cylinder, r = 12 / 2 = 6 ftTo find :-
Volume of cylinderSolution :-
Using formula
Volume of cylinder = π × r² × h
Substitute the value
Volume of cylinder = π × (6ft)² × 14 ft
evaluate the exponent
Volume of cylinder = π × 36 ft ² × 14ft
multiply
Volume of cylinder = π × 504 ft³
Using , π = 3.14
Volume of cylinder = 3.14 × 504 ft³
Hence, the volume of cylinder is 1582.56ft³.
Round nearest tenth place = 1583.4 ft³.

Answer:
BC = 8 cm
Step-by-step explanation:
tan(x) = sin(x)/cos(x)
sin(x) is the opposite side of the angle x.
cos(x) is the side with a right angle to sin(x).
2 = 12/EC
EC = 12/2 = 6 cm
=>
CD = ED - EC = 10 - 6 = 4 cm
now, the same tan(x) relation had to be true for BCD.
tan(x) = BC/CD
2 = BC/4
BC = 8 cm

Answer: 17 square inches.
Step-by-step explanation: Area of a triangle is 1/2 x b x h. We can just take the area of half of the whole triangle, and double it. In this case, half of the triangle has an area of 1/2 x 3.4 x 5 = 8.5. Doubling it is the same is doing 8.5 x 2, which equals 17.

Find the radius y of circle C, given that x = 12 and z = y + 8.
PLEASEEE HELP ME
The radius of the given circle is 5, option C is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
In the given figure, y is the radius.
By pythagoras theorem we find the radius
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
AC²+AB²=BC²
y²+12²=(y+8)²
y²+12²=y²+64+16y
144=16y+64
Subtract 64 from both sides
144-64 = 16y
80=16y
Divide both sides by 16
y=5
Hence, the radius of the given circle is 5, option C is correct.

A ladder that is 20 feet long leans against the wall of a building such that its base makes a 62 degree angle with the ground. Determine the height, h, that the ladder reaches up the wall. Round your answer to the nearest tenth of a foot.
Answer:
17.7 ft
Step-by-step explanation:
A ladder that is 20 feet long leans against the wall of a building such that its base makes a 62 degree angle with the ground. Determine the height, h, that the ladder reaches up the wall. Round your answer to the nearest tenth of a foot.
We solve using the Trigonometric function of sin
sin = Opposite/Hypotenuse
Opposite = Height = ?
Hypotenuse = Length of the ladder = 20 ft
Hence:
sin 62 = h/20 ft
Cross Multiply
h = sin 62 × 20 ft
h = 17.658951857 ft
Approximately = 17.7 ft

Find the area of each figure. Use 3.14
===============================================================
Explanation:
The top and bottom semicircles can be joined to form a full circle. The same can be said about the left and right semicircles. Each circle has diameter 3 and radius 1.5
The area of one circle is
A = pi*r^2
A = 3.14*(1.5)^2
A = 7.065
So two circles doubles to 2*7.065 = 14.13 square meters in area.
Then the last step is to add on the area of the 3 by 3 square (area 3*3 = 9) to get 14.13+9 = 23.13
This area is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate area. However, your teacher wants you to use this specific value so it's best to stick with 23.13
Answer:
23.14
Step-by-step explanation:
The shape is basically two equal-sized circles and a square.
Find the area of the square: 3 x 3 = 9
9 is the area of the square
The formula for finding the area of a circle is pi x radius squared.
3.14 x 1.5 squared = 7.06858
Round to 7.07 and multiply by 2 = 14.14
14.14 (area of both circles) + 9 (area of square) = 23.14

Answer:
D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Since you want to eliminate y, the y value on the bottom equation has the be the opposite of the y value on the top one. So it's 4y on the top one, so the bottom one has to be -4y to eliminate y. The bottom one is -2y, so -2 times 2 =-4, so multiply the bottom one by 2 omg i miss linear combination

Explanation:
The terms of the given expression rearrange to [tex]\frac{1}{3}x^2 - 6x+7[/tex] which is now in standard form (the exponents decrease when moving from left to right).
We can see that
a = 1/3
b = -6
c = 7
