A rectangle length 34m x width 42m. what is the area of the rectangle
Answer: 1428m
Step-by-step explanation: The formula for a regular rectangle is l x w = A, or Length x Width = Area. So, if you replace L with 34 and W with 42, you will get your answer by multiplying the numbers
A sphere has a diameter of 11 inches. What is its surface area? Use 3.14 to approximate π. Round to the nearest hundredth if necessary.
Answer:
The surface area is [tex]379.94in^2[/tex]
Step-by-step explanation:
Given
Shape: Sphere
[tex]D= 11\ in[/tex] - -- Diameter
Required
Determine the surface area (A)
This is calculated using:
[tex]A = 4\pi r^2[/tex]
Where
[tex]r = \frac{1}{2}D[/tex]
[tex]r = \frac{1}{2}*11[/tex]
[tex]r = 5.5[/tex]
So, we have:
[tex]A = 4 * 3.14 * 5.5^2[/tex]
[tex]A = 4 * 3.14 * 30.25[/tex]
[tex]A = 379.94[/tex]
Hence, the surface area is [tex]379.94in^2[/tex]
Answer:
379.94

solve an equation with two real solutions practice
Answer:
x=2.5
Step-by-step explanation:
bring all terms to one side
[tex]4x^{2} -20x+25=0[/tex]
factor it
[tex](2x-5)^{2}=0[/tex]
2x-5=0
2x=5
x=2.5
Answer:
20/33
Step-by-step explanation:
4*2-13x=7x-25
8-13x=7x-25
(subtract 7 x's)
8-20x= -25
(subtract 8)
-20x= -33

nancy lives on a corner lot. cutting across a lot that is 36 feet, and 8 ft longerthan the width.find the length and width if the lot
Answer:
The length of the lot is 13 feet, and the width is of 5 feet.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
[tex]P = 2(l + w)[/tex]
Lot of 36 feet:
Rectangular, so [tex]P = 36[/tex]
Length 8 feet longer than the width:
This means that [tex]l = 8 + w[/tex]
Finding the width:
[tex]P = 2(l + w)[/tex]
[tex]2(8 + w + w) = 36[/tex]
[tex]16 + 4w = 36[/tex]
[tex]4w = 20[/tex]
[tex]w = \frac{20}{4}[/tex]
[tex]w = 5[/tex]
Finding the length:
[tex]l = 8 + w = 8 + 5 = 13[/tex]
The length of the lot is 13 feet, and the width is of 5 feet.

In this figure, sin(a) = 2/3
What is the value of cos(b) ?
9514 1404 393
Answer:
C) 2/3
Step-by-step explanation:
In order to answer the question, we must make an assumption about the given figure. We must assume it is a rectangle, so the left side and right side of the figure are the same length.
The ratio of the right side of the figure to the diagonal is sin(a). The ratio of the left side of the figure to the diagonal is cos(b). If we assume that the left and right sides are the same length, then ...
sin(a) = 2/3 = side/diagonal = cos(b) = 2/3
_____
Additional comments
The figure does not have enough information to support our assumption. Of the answer choices, only (A) is a reasonable alternative. (The value of the cosine must be at most 1.)
The first attachment shows the figure with sin(a) = cos(b) = 2/3. The second attachment shows the figure with cos(b) = 1/3. There is nothing in the given drawing to say this is an incorrect interpretation. (Drawings cannot be assumed to be to scale.)

Emma has already taken 6 pages of notes on her own, and she will take 4 pages during each hour of class. Write an equation that shows the relationship between the time in class (h) and the number of pages (p).
Answer:
6 + (p x h)
Step-by-step explanation:
well, Emma already has the 6 pages so we can push that to the side, but for every hour, she will write 4 more pages, so it would be p x h, but that’s most importnant so you put that in parentheses so you can add the 6 back later.

wht do i put in the square box ?
Answer:
3.75
Step-by-step explanation:
Volume = length x width x height
= 2.5 x 1 x 1.5
= 3.75 cm^3
WE count number of blocks for all values seperately, like
for height its three blocks and one block is equal to 1/2
so.
1/2 x 3= 1.5
