Step-by-step explanation:
9/10 x 1/2 = 9/20
Answer:
The area of the field is [tex]\frac{9}{20}[/tex] [tex]miles^{2}[/tex]
Step-by-step explanation:
To get the area, multiply the length and the width together: [tex]\frac{9}{10}[/tex] * [tex]\frac{1}{2}[/tex] = [tex]\frac{9 * 1}{10*2}[/tex] = [tex]\frac{9}{20}[/tex][tex]miles^{2}[/tex].

Which expression can you substitute in the indicated equation to solve the system below 5x+y =8 x+4y=2
Answer:
x = 1.58 and y = 0.105
Step-by-step explanation:
Given equations are :
5x+y =8 ...(1)
x+4y=2 ...(2)
Multiply equation (2) by 5.
5x+20y=10 ..(3)
Subtract equation (1) from (3).
5x+20y-(5x+y) = 10-8
5x+20y-5x-y = 2
19y = 2
y = 0.105
Put the value of y in equation (2).
x+4(0.105)=2
x = 2-0.42
x = 1.58
Hence, the values of x and y are 1.58 and 0.105.

A buoy is floating in the sea and can be seen from the top of a vertical cliff. A boat is travelling from the base
of the cliff directly towards the buoy. The top of the cliff is 142 m above sea level. The angle of depression
from the top of the cliff to the buoy is 40 degrees.
Answer:
169.23m
Step-by-step explanation:.
Let's calculate the base of the cliff. Using SOH CAH TOA identity
Height (opposite) = 142n
Angle of depression = 40°
Required
Base of the cliff
Tan theta = opposite/adjacent
Tan 40 = 142/x
x = 142/tan40
x = 142/0.8391
x = 169.23m
Hence the base of the cliff is 169.23m long

common denominator for 3/5 and 1/2
Answer: 10
Step-by-step explanation:
To find a common denominator, simply multiply the denominator and numerator of one fraction by the denominator and numerator of the other. Then repeat.
3*2/5*2 = 6/10
1*5/2*5=5/10
As you can see, the denominator of both fractions is 10.
Hope it helps and lmk if you need further explanation :)
solve for x and y 5x + 3y=35, 2x+4y=28
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
5x+3y=35;2x+4y=28
Step: Solve 5x+3y=35 for x:
5x+3y=35
5x+3y+−3y=35+−3y(Add -3y to both sides)
5x=−3y+35
5x/ 5 = −3y+35/ 5 (Divide both sides by 5)
Step: Substitute −3/ 5 y+7 for x in 2x+4y=28:
2x+4y=28
2( −3/ 5 y+7)+4y=28
14/ 5 y+14=28 (Simplify both sides of the equation)
14/ 5 y+14+−14=28+−14 (Add -14 to both sides)
14/ 5 y=14
14/ 5 y/ 14/ 5 = 14/ 14/ 5
(Divide both sides by 14/5)
y=5
Step: Substitute 5 for y in x= −3/ 5 y+7:
x= −3/ 5 y+7
x= −3/ 5 (5)+7
x=4 (Simplify both sides of the equation)
Answer:
x=4 and y=5
Determine if the following ratios form proportions.
1.) 1 to 3 and 7 to 21
2.) 3 to 4 and 24 to 18
3.)1:5 and 6:30
for brainiest:)
Answer:
1. Proportional
2. Not proportional
3. Proportional
Step-by-step explanation:
We have three questions with 2 ratios and are asked if they are proportional or not.
To define proportionality, basically its if the two ratios equal the same value when put in a certain way.
And that way is :
[tex]\frac{x}{y} =\frac{x}{y}[/tex]
You will substitute the numbers with the letters, in which you will cross multiply :
[tex]\frac{x * y}{x*y}[/tex]
So subtitute :
1.
[tex]\frac{1}{3} *\frac{7}{21}[/tex]
[tex]\frac{1*21}{7*3}[/tex]
[tex]21=21[/tex]
Therefore 1. is proportional.
2.
[tex]\frac{3}{4} *\frac{24}{18}[/tex]
[tex]\frac{4*24}{3*18}[/tex]
[tex]\frac{96}{54}[/tex]
96 = 54
Therefore 2. is not proportional.
3.
[tex]\frac{1}{5} *\frac{6}{30}[/tex]
[tex]\frac{1*30}{5*6}[/tex]
[tex]\frac{30}{30}[/tex]
30 = 30
Therefore 3. is proportional.

15n + 24 − 4(n − 3)+ 6 − 2n = 105
Answer:
si por que esta bien hecha
1.Distribute
1 5n+24-4(n-3(+6-2n=105
15n+24-4n+12+6-2n=105
2.Add the numbers
15n+24-4n+12+6-2n=105
15n+42-4n-2n=105
3.Combine like terms
15n+42-4n-2n=105
9n+42=105
4.Subtract 42 from both sides of equation
9n+42=105
9n+42-42=104-42
Simplify
Subtract
9n+42-42=105-42
9n=105-42
subtract again
9n=63
Divide both sides of the equation by the same term
9n=63
9n/9=63/9
Simplify
Cancel terms that are in both the numerator and denominator
9n/9=63
n=63/9
Divide the numbers
n=7
so the answer is n=7
which equation would be the easiest to solve first by using the substitution method? EXPLAIN WHY
equation 1: 3x+5y= -8
equation 2: x- 2y=1
Answer:
Equation 2: x - 2y = 1
Step-by-step explanation:
The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true. Furthermore, if you substitute a 0 for y you automatically know that x = 1.
If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.
What is the area of the figure below?
Answer:
104
Explanation:
1. Split the figure by the line the larger portion creates.
2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.
3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.
4. Now, we simply do 6 · 8 = 48. Almost there!
5. Finally, add the values of the left side and the right side (48 + 56 = 104)
6. YOUR ANSWER IS 104 cm squared.
In ΔJKL, the measure of ∠L=90°, KL = 11 feet, and JK = 32 feet. Find the measure of ∠J to the nearest tenth of a degree.
Answer: J = 20.1

Eighty percent of a roof, or 2800 square feet of the roof, has been re-shingled.
What is the total area of the roof?
A 35,000 sq ft
B 22.400 sq ft
C 3500 sq ft
D 2240 sq ft
Answer:
a) 35,000 sq ft
Step-by-step explanation:
x = total area
the question is: 80% of what number equals 2800
.8x = 2800
x = 2800/0.8
x = 3500

FIND THE equation of the linear function represented by the table below in slope intercept form
Answer:
y= -2x - 1
Step-by-step explanation:
Take two of the points given by the data in the table.
Using the x-values 1 and 2, they have a y-value of -3 and -5, respectively.
Therefore, we can write these out as coordinate points: (1, -3) and (2, -5).
The equation to find the slope of a line is:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Substitute these points into this formula to find the slope of this linear function.
[tex]\displaystyle m= \frac{-5-(-3)}{2-1}[/tex]Simplify and solve for the slope m.
[tex]\displaystyle m=\frac{-2}{1} =-2[/tex]The slope of this linear function is -2. Now, we can use this slope and substitute it into the point-slope equation along with another one of the points on the function.
Point-slope equation:
[tex]y-y_1=m(x-x_1)[/tex]Substitute m = -2 and the point (1, -3) into this equation.
[tex]y-(-3)=-2(x-1)[/tex]Simplify this equation and put it into slope-intercept form: [tex]y=mx+b[/tex].
[tex]y+3=-2x+2[/tex] [tex]y=-2x-1[/tex]The equation of the linear function represented by the table is y = -2x - 1.
Answer:
y= -2x - 1
Step-by-step explanation:
Take two of the points given by the data in the table.
Using the x-values 1 and 2, they have a y-value of -3 and -5, respectively.
Therefore, we can write these out as coordinate points: (1, -3) and (2, -5).
The equation to find the slope of a line is:
Substitute these points into this formula to find the slope of this linear function.
Simplify and solve for the slope m.
The slope of this linear function is -2. Now, we can use this slope and substitute it into the point-slope equation along with another one of the points on the function.
Point-slope equation:
Substitute m = -2 and the point (1, -3) into this equation.
Simplify this equation and put it into slope-intercept form: .
The equation of the linear function represented by the table is y = -2x - 1.
