can you show a video or a pic of the answer 3.4 mi/h = ft/sec
Answer:
4.99 ft/sec
Step-by-step explanation:
1 mile = 5280 feet
3.4 miles = 17952 feet or (3.4 x 5280= 17952)
1 hour = 3600 seconds (60 minutes per hour x 60 seconds per minute)
17952 feet / 3600 seconds = 4.99 feet per second

it takes 3 tractors 2 hours to plow a square field whose side is 600 meters. find the number of hours it would take 5 tractors to plow a square field whose side is 1000 meters.
PLEASE ANSWER FAST. 200 POINTS
Answer:
5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)
Step-by-step explanation:
Let's find out how much each tractor can plow each hour.
[tex]\frac{600^{2} }{3*2}=60,000m^{2}[/tex] per tractor per hour
[tex]1,000^{2}=1,000,000m^{2}[/tex] is the area of the field of side length 1,000 meters
5 tractors can plow [tex]300,000m^{2}[/tex] per hour.
[tex]\frac{1,000,000}{300,000}=3.33[/tex] hours

Allister, who is 5 feet tall, is standing three feet from a mirror lying on the ground. When he looks into the mirror, he can just see the top of a tree that is 24 feet away from the mirror. Make a sketch of this situation, and use it to calculate the height of the tree
Answer:
40 feets
Step-by-step explanation:
Given that :
Observer's height = 5 feets
Observer's distance from the mirror = 3 feets
Distance of tree away from the mirror = 24 feets
To obtain the height of tree:
Observer's distance (Od) / tree distance (Td) = Observer's height(Oh) / tree height (Th)
Od / Td = Oh / Th
3 / 24 = 5 / Th
3 * Th = 24 * 5
Th = 120 / 3
Th = 40 feets
Hence, the height of tree is 40 feets

Bisect means that the angles are split equally.
RTV would be half of RTS
RTV = 1/2(RTS)
16x-6 = 1/2(26x+18)
Simplify:
16x - 6 = 13x +9
Subtract 13x from both sides:
3x - 6 = 9
Add 6 to both sides:
3x = 15
Divide both sides by 3:
x = 5
Now you have x, replace x in the equation for RTV:
RTV = 16x -6 = 16(5) -6 = 80 - 6 = 74
RTV = 74 degrees.
Vivek worked 35 hours and earned $385. At this rate, how many hours would it take him to earn $143?
A. 11
B. 13
C. 17
D. 19
HURRY ANSWER IT
Answer:
B. 13
Step-by-step explanation:
Time taken to earn $385 = 35 hours
Time taken to earn $1 = [tex] \sf \dfrac{35}{385} [/tex] hours
[tex] \sf = \dfrac{1}{11} \ hours [/tex]
Time taken to earn $143 = [tex] \sf \dfrac{1}{11} \times 143 [/tex] hours
[tex] \sf = 13 \ hours [/tex]

Answer:
[tex]k=14[/tex]
Step-by-step explanation:
Given:
[tex]x^{2}+kx+49 = 0[/tex]
[tex]x = -7[/tex]
Substitution can be used to find the value of [tex]k[/tex]:
[tex](-7)^{2}+(-7)k+49 = 0[/tex]
[tex]49-7k+49 = 0[/tex]
[tex]98 -7k = 0[/tex]
[tex]k = 14[/tex]

What is the slope of y = -42 - 3?
Write the equation of the line y=(5)/(6)x+(7)/(6) perpendicular to
that passes through the point (-8,7)
Answer:
6x + 5y + 13 = 0.
Step-by-step explanation:
y = 5/6x + 7/6
Gradient = 5/6
Since the line is perpendicular to y = 5/6x + 7/6
then its gradient is -6/5.
Hence its equation is: point (-8,7).
y - 7 = -6/5(x -(-8))
multiplying through by 5 we get;
5y - 35 = -6(x + 8)
5y - 35 = -6x - 48
6x + 5y + 13 = 0

Tiara earns $33 washing 3 cars. At this rate, how much does Tiara earn washing 9 cars?
Answer:
$99
Step-by-step explanation:
Answer:
$99 (Verified Answer) ✅Step-by-step explanation:
The best way to solve this is to use a proportion. However, since this is a rate, we could also find the unit rate and multiply it by the number of cars Tiara is washing.
Method 1: Proportion[tex]\frac{33}{3} = \frac{x}{9}[/tex]
3x = 33 x 9
3x = 297
Now, we simply divide by 3 to get $99.
We can check this by substituting the value of x in the original proportion.
3(99) = 33 x 9
297 = 297 ✅
Method 2: Unit RateThe other way to solve this is to divide the whole expression by the number of cars to find the unit rate. In other words, how much money does she get for washing 1 car. We can then multiply this by the number of cars to get the answer.
$33/3 for 3/3 cars
$11 for 1 car
Now, we will multiply by the number of cars she washes in this question, which is 9
$11 x 9 = 99 for 1 x 9 cars
$99 for 9 cars
Again, we have the correct answer, which we have already verified by the process above. As you can see, both methods work. However, the top method is easier and since it uses algebra, is almost foolproof, so long as the algebraic processess are followed.

Answer:
Each property is mentioned with the corresponding expression.
Step-by-step explanation:
Writing the property in front of every expression:
1. Additive Identity: 11+0 = 11
2. Associative Property of Multiplication: x*(y*z) = (x*y)*z
3. Additive Identity: 8+(-8) = 0
4. Commutative property of Addition: 14+20=20+14
5. Multiplicative Inverse: 2*1/2 = 1
6. Multiplicative Identity : 22*1 = 22
7. Associative Property of Addition: (19+12)+8=19+(12+8)
8. Commutative Property of Multiplication: a*9=9*a
9. Distributive Property: 7(4+11) = 7(4)+7(11)

Could someone please answer b?
Answer:
b. The total sum of the money was $330
Step-by-step explanation:
#b
∵ A sum of money is divided among John, Paul, and Robert
∵ The ratio of the shares of John, Paul, and Robert is 2: 4: 5
→ Multiply the ratio of each share by x
∴ The share of John = 2x
∴ The share of Paul = 4x
∴ The share of Robert = 5x
→ Find their sum
∴ The sum of the money = 2x + 4x + 5x = 11x
∵ The sum of the money is divided equally among them
→ That means dividing the sum by 3 to find the share of every one
∵ The sum of the money = 11x
∴ The share of every one = [tex]\frac{11x}{3}[/tex] = [tex]\frac{11}{3}[/tex]x
∴ The share of John is larger by $50
→ That means the difference between his shares is 50
∵ [tex]\frac{11}{3}[/tex]x - 2x = 50
∴ [tex]\frac{5}{3}[/tex]x = 50
→ Divide both sides by [tex]\frac{5}{3}[/tex]
∴ x = 30
→ Substitute it in the sum of the money to find it
∵ The sum of the money = 11(30)
∴ The sum of the money = $330
∴ The total sum of the money is $330

a. y = 3/4x - 5 I'm confused on how I'm suppose to find the slope and y-intercept.
Answer:
The slope is 3/4 and the y-intercept is -5.
Step-by-step explanation:
Your equation is already in slope-intercept form, so all you have to do is look at it. Slope-intercept form looks like y = mx + b, where m is the slope and b is the y-intercept. Hope that helps!
