Step-by-step explanation:
The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the length of the dimension of the rectangle.
Answer:
11 ft
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is
A = L * W.
Represent the length, L, by 2W + 1 ("1 more than twice the width"). Then the area formula (above) becomes:
A = 55 ft^2 = (2W + 1)(W), which, when simplified, results in:
2W^2 + W - 55 = 0, whose coefficients are {2, 1, -55}. Let's use the quadratic formula to solve this for W:
The discriminant, b^2 - 4ac, is 1^2 - 4(2)(-55), or 441. The square root of 441 is 21. Thus, the quadratic formula gives us:
-1 ± 21
W = ------------- = (1/4)(-1 + 21), or W = 5 and W = -22/4 = -11/2
2(2)
A measure of length can't be negative, so we reject W = -11/2 in favor of W = 5.
Then, according to the formula for L that we found earlier, L = 2W + 1, or
L = 2(5) + 1, or L = 11.
Check: Does L * W result in an area of 55 ft²? Yes
The length dimension of the rectangle is 11 ft

Step-by-step explanation:
Mr. Torres bought 3 chairs on Saturday. He paid d dollars for each chair. Mr. Torres received $15 dollars in change when he bought the chairs. Which expression can be used to find the total amount Mr. Torres paid for these chairs
Answer: c. 3d + 15
Step-by-step explanation:
Mr. Torres paid d dollars for each of the three chairs which gives the expression of:
= 3 * d = 3d
He then paid with an amount that was greater than this 3d and got a change of $15.
That total amount that he paid is therefore, the price of the three chairs added to the $15 that he received back.
= 3d + 15
Of the 45 staff members at SEMS ,9 were out with the flu one day in January. What percent of the teachers were at work today?
Answer:
80%
Step-by-step explanation:
Given that Of the 45 staff members at SEMS ,9 were out with the flu one day in January, it means that the number of people at work
= 45 - 9
= 36
As a percentage,
= 36/45 * 100%
= 4/5 * 100%
= 80%
The percent of the teachers were at work today is 80%

The approximate volume of first cone is 709[tex]mi^{3}[/tex] and the volume of second cone is 262 [tex]cm^{3}[/tex].
What is volume?Volume is amount of substance a container can hold in its capacity. Volume of cone is basically 1/3 *π[tex]r^{2}h[/tex] in which r is radius and h is height of cone.
How to calculate volume?We have been given two cones. First is having radius of 7 mi and
height 14 mi and second is having radius of 5 cm and height of 10 cm. We are required to find out the volume of both the cones.
Volume of first cone=1/3 *π[tex]7^{2}* 14[/tex]
=(49*3.14*14)/3
=708.86
Approximately 709 [tex]mi^{3}[/tex]
Volume of second cone =1/3π[tex]5^{2} *10[/tex]
=(25*3.14*10)/3
=261.67
Approximately 262 [tex]cm^{3}[/tex].
Hence the approximate volume of first cone is 709[tex]mi^{3}[/tex] and the volume of second cone is 262 [tex]cm^{3}[/tex].

If you had a right triangle with legs measuring 40 yards and 100 yards long,
what would be the length of the hypotenuse? Round your answer to the
nearest yard if necessary. *
70 yd
92 yd
108 yd
146 yd
9514 1404 393
Answer:
(c) 108 yd
Step-by-step explanation:
For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...
c² = a² +b²
Solving for c, we have ...
c = √(a² +b²)
c = √(40² +100²) = √(1600 +10000) = √11600
c ≈ 107.70 . . . . yards
The length of the hypotenuse is about 108 yards.

If y varies directly as x and y = 5.5 when x = 11, find x when y = 3.5
0 x = 7
O x = 6
O x = 1.75
O x = 1.25
Answer:
x=7
Step-by-step explanation:
y=mx
5.5=m×11
5.5÷11=m
m=1/2
y=mx
3.5=1/2×x
3.5÷1/2=x
x=7
Answer:
x =7
Step-by-step explanation:
The direct variation equation is y = kx, where k is the constant of proportionality.
If y = 5.5 when x = 11, we can write 5.5 = 11k, which, when solved for k, yields k = 0.5.
Then the direct variation equation in this case is y = 0.5x.
If y = 3.5, what is x? y = 0.5x becomes 3.5 = 0.5x, yielding x = 7
