Answer:
The scale drawing is correct for the length;
[tex]\overline{BC} = 5\dfrac{34}{35} \ in.[/tex]
Step-by-step explanation:
The diagram shows the rectangular cross-section of a roof truss
The given dimension of the side [tex]\overline{AB}[/tex] of the roof truss scale drawing = 9.5 in.
The actual length of the side [tex]\overline{AB}[/tex] on the roof truss = 38 feet
The actual length of the side [tex]\overline{BC}[/tex] on the roof truss = 22 feet
Therefore, the scale of the scale drawing is given as follows;
The scale of the drawing = (Scale dimension)/(Actual dimension)
38 feet = 9.5 inches on the drawing
∴ 1 foot = 9.5 inches/35 = 19/70 inches on the drawing
1 foot = 19/70 inches on the drawing
22 feet = (19/70 inches × 22) on the drawing = [tex]5\frac{34}{35}[/tex] inches on the drawing
The length of [tex]\overline{BC}[/tex] on the scale drawing = [tex]5\frac{34}{35}[/tex] inches.
Lenni has a rectangular garden with a length of 5x-7 and a width of x-2.
Write an expression for the total perimeter in terms of x.
_______
Lenni measured the perimeter to be 66 feet. What is the value of x? Enter a number only in the box below.
_____ feet
Answer:
ths for the points TEHEHEHEHE
Step-by-step explanation:
Answer:
P = 12x - 18, x = 7 feet
Step-by-step explanation:
We know that the formula for the perimeter of a rectangle is:
[tex]P=2l+2w[/tex]
Where l is the length and w is the width. So we just substitute in for variables:
P = 2 (5x - 7) + 2 (x - 2)
We distribute by foiling:
P = 10x - 14 + 2x - 4
Then combine like terms:
P = 12x - 18
This can be further factored to 6(2x - 3) if needed.
Since we know the expression for perimeter, we can just set it equal to 66 feet, like this:
6(2x - 3) = 66
Divide both sides by 6:
2x - 3 = 11
Add 3 to both sides:
2x = 14
Divide both sides by 2:
x = 7 feet

Answer:
26.41 sq. ft
Step-by-step explanation:
The formula for the area of a circle is
[tex]\pi r^{2}[/tex]
with r being the radius, and knowing the radius of the circle being 2.9 ft, we can substitute 2.9 in for x.
Now we simplify and solve the equation
[tex]\pi 2.9^{2}[/tex]
[tex]\pi 8.41[/tex]
(pi ([tex]\pi[/tex]) = 3.14)
3.14 x 8.41 = 26.4074
Now round to the nearest 100th
26.41
The answer is 26.41 sq. ft

How do I solve this equation by using the quadratic formula 3x^2-12x-27=-6
Answer:
Move all terms to the left side of the equation and simplify.
3x²−12x−21=0
Use the quadratic formula to find the solutions.
(−b±√b²−4(ac))/2a
Substitute the values a=3, b=−12, and c=−21 into the quadratic formula and solve for x.
(12±√(−12)²−4⋅(3⋅−21)0/2⋅3 Simplify => x=2±√11
The result can be shown in multiple forms.
Exact Form: x=2±√11
Decimal Form: x=5.31662479…,−1.31662479…
Step-by-step explanation:
Step-by-step explanation:
The quadratic equation is
x=−b=−√b2−4ac2a
for a quadratic taking the form
ax2+bx+c=0
So for this equation it is
x=−(−12)±√(−12)2−4⋅3⋅112⋅3
x=12±√144−1326
x=12±√4⋅36
x=6±√33
i need help with the volume, tsa and x please
Answer:
Volume = 42 units^2
x = 5 units
Total Surface Area = 96 units
Step-by-step explanation:
Volume
V = bh, where b = 1/2 * 3 * 4 and h = 7,
= 6 * 7 = 42 units^2
x
You can solve for this variable by using the pythagorean theorem;
a^2 + b^2 = c^2, where a = 3 and b = 4,
9 + 16 = x^2
= 25 = x^2
= x = 5 units
Total Surface Area
You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:
7 * (3 + 4 + 5) + 2(1/2*3*4)
= 7*12 + 12
= 96 units

Answer:
b^8
Step-by-step explanation:
Answer:
b^8, with m = 8
Step-by-step explanation:
Apply the algebraic rule: (x^a)/(x^b) = x^(a-b)
Note: This rule is true because we can cancel all b factors that occur in both numerator and denominator.
From this rule, we know that (b^10)/(b^2) = b^(10-2)
b^(10-2) can be written b^8

Estimate the volume of a soccer ball that has a diameter of 8 inches
Answer:
269 in³
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³.
Here the ball (sphere) diameter is 8 in, meaning that the radius is 4 in.
Thus, the volume of this ball is:
V = (4/3)π(4 in)³
If an "estimate" is good enough, use 3.14 for π:
V = (4/3)(3.14)(4 in)³ = 269 in³
What is the area of this trapezoid?
44 in²
64 in²
168 in²
192 in²
Answer:
44 in² = 1,936
64 in² = 4,096
168 in² = 28,224
192 in²= 36,864
Step-by-step explanation:
Raise the number to the power of 2.
Ex : 192² raise by the the power of 2 is 36,864
Hope this helps you :)
what is the perimeter of 6 and 2
Answer:
In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.
Step-by-step explanation:
To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

At what value of x does the graph of the following function F(x) have a
vertical asymptote?
A. 2
B. 2
C. -1
D. 0
Given:
The function is
[tex]F(x)=\dfrac{1}{x+2}[/tex]
To find:
The vertical asymptote of the given function.
Solution:
Vertical asymptote are the vertical line passes thought the values for which the function is not defined.
To find the vertical asymptote, equate the denominator equal to 0.
We have,
[tex]F(x)=\dfrac{1}{x+2}[/tex]
Denominator is (x+2).
[tex]x+2=0[/tex]
[tex]x=-2[/tex]
The vertical asymptote is [tex]x=-2[/tex].
Therefore, the correct option is B.
Write the equation of a circle that has a center of (-4, 2) and has a radius of 7.
Answer:
(x + 4)² + (y - 2)² = 49Step-by-step explanation:
The center is (h, k) = (-4, 2) ⇒ h = -4, k = 2The radius r = 7The equation is:
(x - h)² + (y - k)² = r²(x - (-4))² + (y - 2)² = 7² ⇒ (x + 4)² + (y - 2)² = 49Sheila is biking at a constant speed. She travels 54 meters in 9 seconds.
Part A
How many meters per second does Sheila travel?
Part B
How long in seconds would it take Sheila to travel 90 meters at this speed?
Answer:
6 m/s
15 seconds
Step-by-step explanation:
Speed = distance / time
54 / 9 = 6 m/s
Given the same speed, we can determine the time she would use to travel
time = distance / speed = 90 / 6 = 15 seconds
