Answer:
B. the area of a rectangle with side lengths 1.40 and x
Step-by-step explanation:
To find the area of a rectangle, multiply the length by the width.
If 1.40 is the length, x is the width.
1.40×x=1.40x
So B is the correct answer.
sin x=0.6, x lies in quadrant two.
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Here we go ~
[tex]\qquad \tt \dashrightarrow \: \sin(x) = 0.6[/tex]
[tex]\qquad \tt \dashrightarrow \: \sin(x) = \dfrac{6}{10} [/tex]
[tex]\qquad \tt \dashrightarrow \: \sin(x) = \dfrac{3}{5} [/tex]
[tex]\qquad \tt \dashrightarrow \:x = \sin {}^{ - 1} ( \dfrac{3}{5} ) [/tex]
[tex]\qquad \tt \dashrightarrow \:x = 37 \degree[/tex]
Now, since we have to find the value of x in quadrant 2, we have to subtract the given value from 180°
that is :
[tex]\qquad \tt \dashrightarrow \:x = 180 - 37[/tex]
[tex]\qquad \tt \dashrightarrow \:x = 143 \degree[/tex]
what is the equation in slope-intercept form of the line that passes through the points (-26,-11) and (39,34)?
Answer:
y = [tex]\frac{9}{13}x + 7[/tex]
Step-by-step explanation:
Slope (m):
34 - (-11)/39 - (-26) = 45/65 = 9/13
y-intercept (b):
34 = (9/13)39 + b
7 = b
the equation is:
y = (9/13)x + 7

Water is pouring into a conical vessel of diameter 5.2m and slant height 6.8m (as shown in the adjoining figure), at the rate of 1.8 m per minute. How long will it take to fill the vessel?
Answer:
31.6m
Step-by-step explanation:
First, find area of the vessel [ (πr2h)/3 ]
Radius = 5.2/2= 2.6
Using Pythagorean theorem, find the height of the cone:
[tex]\sqrt{6.8^{2} -5.2^{2} }[/tex] = 4.38
Area of vessel = [tex]\frac{ (PI * 2.6 * 2 * 4.38)}{3}[/tex] = 56.88 [tex]cm^{3}[/tex]
Do cross multiplication using ratios:
1.8 = 1
56.88 = [tex]x[/tex]
[tex]\frac{56.88}{1.8}[/tex]= 31.6

PLS HELPPPPPP
Answer:
The deck's width is 9 feet
The deck's area is 18 feet
Correct po yan
Hope it helps po
Answer:
Deck Width: 6 Feet
Deck Area: 72 Feet Squared
Step-by-step explanation:
[l = length, w = width, f = feet, p = perimeter, a = area]
A = l x w
P = 2l + 2w [l = 12f, p = 36f]
P = 2l + 2w
=> 36f = 2 (12f) + 2w
=> 36f = 24f + 2w
=> 36f - 24f = 2w
=> 12f = 2w
=> 2w/2 = 12f/2
=> W = 6f
Therefore: Width = 6 Feet
A = l × w
A = 12f × 6f
A = 72f^2
Therefore: Area = 72 Feet Squared
The national average utility cost is $270.48 per month. if the average electric bill is 44.9% of the total amount and the average utility cost for orlando, fl is $308.83, what would be the cost of a typical orlando electric bill and how would that compare with the national average? a. the typical orlando electric bill would be $138.66, which would be $17.21 more than the national average. b. the typical orlando electric bill would be $121.54, which would be $17.21 less than the national average. c. the typical orlando electric bill would be $138.66, which would be $76.64 more than the national average. d. the typical orlando electric bill would be $121.54, which would be $76.64 less than the national average.
The typical Orlando electric bill would be $138.66, which would be $17.21 more than the national average option (a) is correct.
It is given that the national average utility cost is $270.48 per month. if the average electric bill is 44.9% of the total amount and the average utility cost for Orlando, fl is $308.83.
It is required to find the cost of a typical Orlando electric bill and how would that compare with the national average.
What is average?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
We have:
Average utility cost = $270.48
Average electric bill = 44.9%
Average utility cost without electric bill = [tex]270.48\times \frac{44.9}{100}[/tex]
= $121.44
Typical orlando electric bill = [tex]308.83\times \frac{44.9}{100}[/tex]
= $138.66
Now,
=$138.66 - $121.44
= $17.22
Thus, the typical Orlando electric bill would be $138.66, which would be $17.21 more than the national average option (a) is correct.

Answer:
Perimeter of rectangle = 14x - 2
Area of rectangle = 10x² + x - 2
Step-by-step explanation:
Finding the perimeter of the rectangle:
⇒ Perimeter of rectangle = 2(L) + 2(B)
⇒ Perimeter of rectangle = 2(2x + 1) + 2(5x - 2)
⇒ Perimeter of rectangle = 4x + 2 + 10x - 4
⇒ Perimeter of rectangle = 14x - 2
Finding the area of the rectangle:
Area of rectangle = LB
⇒ Area of rectangle = (2x + 1)(5x - 2)
⇒ Area of rectangle = 10x² - 4x + 5x - 2
⇒ Area of rectangle = 10x² + x - 2
Answer:
Perimeter = 14x - 2
Area = 10x² + x - 2
Step-by-step explanation:
Formulae
Perimeter = 2W + 2L Area = W x L(where W is the width and L is the length)
Given information
width = 2x + 1length = 5x - 2Perimeter
⇒ Perimeter = 2(2x + 1) + 2(5x - 2)
= 4x + 2 + 10x - 4
= 14x - 2
Area
⇒ Area = (2x + 1)(5x - 2)
= 10x² - 4x + 5x - 2
= 10x² + x - 2

Step-by-step explanation:
These shapes are mathematically similar as line BR and QC are parallel.
To find the scale factor:
First we find the length of BD by adding 26 and 39:
26+39 = 65
So to get from BD to BQ :
We multiply by :
26/65 = 0.4
So to get from RD to CD:
We do
18÷0.4 = 45
Then we subtract 18 from 45 to get x:
45-18 = 27
Therefore the value of x is 27
The boundary line on the graph represents the equation x-3y=5. Write an inequality that is represented by the graph.
Answer:
y > 1/3x - 5/3
x-3y < 5
Step-by-step explanation:
We simplify x-3y=5, to y = 1/3x - 5/3
We notice the boundary line is dotted, we know the inequality must be < or > rather than ≤ or ≥.
The shading is above the line which indicates that in y-intercept form we must use >.
y > 1/3x - 5/3
or x-3y < 5
Either of these show the exact same thing.
