Answer:
He can plant 10 trees in 2 hours.
Step-by-step explanation:
First you need to find the number of trees he can plant in an hour.
For this purpose, we will divide 40 by 8 to get an idea about how many he can plant in an hour.
Trees planted in an hour = 40/8 = 5
Now for 2 hours = 5*2 = 10 trees.

The time, t, in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation.
t=√2d/a
Which equation expresses d in terms of t and a?
A. d=2at^2
B. d=√2t/a
C. d=at^2/2
D. √a/2t
Answer:
(A)
Step-by-step explanation:
Option A. d=2at^2

Can an object accelerate if it's moving with constant speed?
Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.

Find the y-intercept of the line on the graph.
Enter the correct answer
Given:
The graph of a line.
To find:
The y-intercept of the line.
Solution:
y-intercept of a line is the point at which the line intersect the y-axis.
We have, graph of the line.
From the given graph it is clear that the line intersect the y-axis at (0,4).
So, y-intercept is at point (0,4).
y-intercept = 4
Therefore, the y-intercept is 4.

Answer:

Step-by-step explanation:
Answer:
2x + 19.
Step-by-step explanation:
The reasoning behind this is that one must find the disparity between the first and second expressions - 9x+14 and 7x-5. To do this, one subtracts 7x-5 from 9x+14. Set this up as though it were a normal subtraction problem - 9x+14 over 7x-5 with the little subtraction symbol to the left. When subtracting the negative five from fourteen, one adds the five to the fourteen due to the fact that the five was already negative and as such the negatives cancel out. The 7x is simply subtracted from the 9x, resulting in 2x. This leads to 2x + 19.
Elena paints the back of a aquarium it has a height of 1 3/4 feet the painted area is 5 5/6 what is the length
Answer:
3 1/3 feets
Step-by-step explanation:
Given that:
Height of aquarium = 1 3/4 feets
Area of aquarium = 5 5/6 ft²
The length of aquarium = x
Aquarium is shaped in the form of a rectangle :
Area of a rectangle = Length * width
5 5/6 = x * 1 3/4
35/6 = 7x/4
Cross multiply :
7x * 6 = 35 * 4
42x = 140
x = 140 / 42
x = 3 14/42
x = 3 1/3 feets
Hence, Length of the back of aquarium is 3 1/3 feets
Evaluate the expression.

z=5
x=9
y=3
plug the numbers into a calculator
(9-3)=6
5^2=25
25*6=150
Step-by-step explanation: To handle these evaluation problems, you must be able to deal with positives and negatives, and you must know your order of operations. In addition, it's a good idea to get into the habit of using parenthses when substituting numbers in for variables.
Notice that we have a set of parenthses in our problem and remember that we use parenthses when substituting our numbers into the problem.
To avoid the confusion of having too many sets of parenthses,
let's change the parenthses in the original problem to brackets.
Now let's substitute using parenthses.
So we have (5)² · [(9) - (3)].
Since the parenthses were in the original problem were replaced
by brackets and parenthses come first in your order of operations,
in our problem the brackets are going to come first.
So first simplify 9 - 3 which is 6.
So we have (5)² [(6)].
Exponents come next so we square the 5 to get 25
and that gives us (25) [(6)] which is 150.

Terry pays £480 per month in rent.
His landlord decides to increase the rent by 7.5%.
How much rent does he pay now?
Answer: £516
Step-by-step explanation:
7.5 increase = 100 + 7.5 = 107.5
107.5/100 = 1.075 (multiplier)
480 x 1.075 = 516
Find the value of x.
Answer:
The value of x is 120°
Step-by-step explanation:
We should draw a line parallel to the given parallel lines and passes through the vertex of the measure x and divides it into two angles of measures x1 and x2, look at the attached figure
In the given figure
∵ The dashed line is parallel to the given line up
∴ The angle of the measure 70° and the angle x1 are alternate angles
∵ The alternate angles are equal in measures
∴ x1 = 70°
∵ The dashed line is parallel to the given line down
∴ The angle of the measure 50° and the angle x2 are alternate angles
∵ The alternate angles are equal in measures
∴ x2 = 50°
∵ x = x1 + x2
∴ x = 70 + 50
∴ x = 120°
∴ The value of x is 120°
Answer:
x= 120
Step-by-step explanation:
Alternated angles are 50 and 70
Angles of a triangle sum 180

4 2/5+k=−3 2/11
Need help
Answer:
2/11
Step-by-step explanation:
Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"
4 2/5 + k = -3 2/11
I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.
4 2/5 + k = -3 -2/11
k = - 3 - 4 - 2/5 - 2/11
k= - 7 -2/5 -2/11
Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.
k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)
k = - 385/55 - 22/55 -10/55
k = - (385 +22+10)/55
k = - 417/55
Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.
btw correct me if i am wrong
Answer:
[tex] k = - 1 \frac{12}{55} [/tex]
Step-by-step explanation:
[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]

log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
Step-by-step explanation:
for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477
and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219
Step-by-step explanation: Using Properties of Logs
logb(x/y) = logbx - logby.
Furthermore
log5 (4/7)= log5 (4)- log5 (7)
Solve log 5 (4) and log 5 (7) with the base change of the logarithm
log 5 4 = log 4 / log 5
Use the calculator (DESMOS): log 5 4 =0.8613531161
log 5 7 = log 7 / log 5
log 5 7 =1.2090619551
Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
For the second part of the question just to not make this too long the answer to the second part is: C ( -2.3219 )

A store is having a 20% off sale on all merchandise 1. If Mai buys one item and saves $13 what was the original price
Answer: $65
Step-by-step explanation:
The store is having a 20% off sale.
Mai buys an item and saves $13.
This means that $13 is 20% of the price of the item that Mai bought.
Assume the original price is x. Expression is:
x * 20% = 13
x = 13/20%
x = $65
