Find the area of a triangle: Base of 8 cm Hight of 9 cm
Answer:
36 cm
Step-by-step explanation:
The formula to find the area of a triangle is A=1/2bh where b stands for base and h for height.
So, 8 times 9 equals 72, and 72 divided by 2 is 36.
Gerry plans to place a 29 foot ladder against the side of his house to clean his gutters. The bottom of the ladder will be 3 feet from the house. How far up the side of the house will the ladder reach (in ft)?
Answer:
8[tex]\sqrt{13}[/tex]
Step-by-step explanation:
Using the pythagorean theorem (Assuming the house's walls are perpindicular to the ground):
a^2+b^2=c^2
we can find that 3=a and 29=c
3^2+b^2=29^2
9+b^2=841
b^2=832
b=[tex]\sqrt{832}[/tex]
b=[tex]\sqrt{64*13}[/tex]
b=8[tex]\sqrt{13}[/tex]
That is the height that the ladder will reach

Step-by-step explanation:
0.625 rounded to the nearest thousandth
Answer:
the answer is still 0.625
Step-by-step explanation:
the tenths digit is 6, the hundreds digit is 2 and the thousabds digit it 5. SInce it doesn't pass the thousands digit it's fine how it is.
The round off of 0.625 to the nearest thousandth results in 0.626.
To round 0.625 to the nearest thousandth, focus at the digit in the thousandth's place, which is the third decimal place.
In this case, the digit in the thousandth's place is 5.
Since 5 is exactly halfway between 0 and 10, we round up the previous digit, which is 2.
Therefore, rounding 0.625 to the nearest thousandth results in 0.626.

b. Determine the cost of the flooring if she decides on a dining room with side lengths of 11 ft.
c. Determine the cost of the flooring if she decides on a dining room with side lengths of 23 ft
Answer:
A F = 3.39 per sq ft. B 37.29 C 77.97
Th function is f(x) = 3.39x²
The cost of the flooring for a dining room is $410.19.
The cost of the flooring for a dining room is $6,072.31.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Area of a square = side²
Square with side lengths = x feet.
The tile costs = $3.39 per square foot.
a.
The function f for the cost of the flooring.
f(x) = 3.39x²
b.
x = 11 feet
f(11) = 3.39 x 11²
f(11) = 3.39 x 121
f(11) = $410.19
c.
x = 23 feet
f(23) = 3.39 x 23²
f(23) = 3.39 x 529
f(23) = $6,072.31
Therefore,
f(x) = 3.39x²
The cost of the flooring for a dining room is $410.19.

Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4). What is the y-coordinate of the midpoint of line segment YZ?
Given:
Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4).
To find:
The y-coordinate of the midpoint of line segment YZ.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
The endpoints of the line segment YZ are Y(-3,-6) and Z(7,4). So, the midpoint of YZ is:
[tex]Midpoint=\left(\dfrac{-3+7}{2},\dfrac{-6+4}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{4}{2},\dfrac{-2}{2}\right)[/tex]
[tex]Midpoint=\left(2,-1\right)[/tex]
Therefore, the y-coordinate of the midpoint of line segment YZ is -1.

Answer:
y=-3x+10
Step-by-step explanation:
Since you know that the equation of the line is perpendicular to 1/3, you have to find the inverse of 1/3. You swap the denominator and numerator and make the number negative. In this case, it will be -3. Now that you know the slope is -3, you can use the equation y-y1=m(x-x1) where m is the slope. We know that the point (2,4) is in the graph so we can plug it into the equation. y-4=m(x-2). We know that the slope is -3 so we can plug it into the equation. y-4=-3(x-2). Simplify this to get y-4=-3x+6. Simplify this to get y=-3x+10. This means that the answer is y=-3x+10.

Step-by-step explanation:
The base of a cylinder is a circle, so we need to calculate the area of the circle first. The equation for the area of a circle is:
area (a) = pi * r^2 =3.14*2*2 =12.56sq.inches
again,
volume of cylinder = area of the base * the height
= 12.56 * 7
= 87.92 inches cubed or 87.92 in.^3
