A tree that is 4 ft tall is growing at a rate of 1 ft each year a tree that is 12 feet tall is growing at a rate of 1/2 ft each year how many years will it take the two trees to reach the same height
Answer:
16 years
Step-by-step explanation:
Given data
For the first tree
let the expression for the height be
y=4+x--------------1
where y= the total height
4= the initial height
x= the number of years
For the second tree, the expression is
y=12+0.5x-------------2
Equate 1 and 2
4+x=12+0.5x
x-0.5x=12-4
0.5x= 8
x= 8/0.5
x=16
Hence it will take 16 years for both trees to have the same height
a+7=a-...
a-18=a+...
Which choice represents the equation
a? + b2 = c2 after it has been solved for b?
The distances and times from a track meet for four schools are shown.
School has the fastest average time per mile at the track meet.
Answer:
Average time for West Middle was maximum.
Step-by-step explanation:
Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]
For Eastbay Middle,
Average time per mile = [tex]\frac{42}{7}[/tex]
= 6 minutes per mile
For Northwest Middle,
Average time = [tex]\frac{25}{5}[/tex]
= 5 minutes per mile
For South Central Middle,
Average time = [tex]\frac{28}{4}[/tex]
= 7 minutes per mile
For West Middle,
Average time = [tex]\frac{48}{6}[/tex]
= 8 minutes per mile
Therefore, average time for West Middle (8 minutes per minute) was maximum.
Daniel deposits a certain sum of money in a bank. If the simple interest rate of the bank decreases from 3.75% per annum to 3.5% per annum, Daniel's interest will increases by $50 in a year. Find the sum of money he deposits.
The answer is $20000 but I don't understand how. Please give a step-by-step explanation.
Answer: $20,000
Step-by-step explanation:
Given
Interest decreases from 3.75% to 3.5% in a year
This change in the rate of interest brings a yield of 50$
Earlier interest was
[tex]S.I_e=\dfrac{P\times 3.75\times 1}{100}[/tex]
Now, interest is
[tex]S.I._n=\dfrac{P\times 3.5\times 1}{100}[/tex]
change gives 50$ i.e.
[tex]\Rightarrow \dfrac{P\times 3.75\times 1}{100}-\dfrac{P\times 3.5\times 1}{100}=50\\\\\Rightarrow \dfrac{P\times (3.75-3.5)\times 1}{100}=50\\\\\Rightarrow P=\dfrac{50\times 100}{0.25}=\$20,000[/tex]
Consider a collection of envelopes consisting of 3 red envelopes, 1 blue envelope, 2 green envelopes, and 3 yellow envelopes. If two envelopes are selected at random, with replacement, determine the probability that at least one envelope is a red envelope.
Answer: The probability that at least one of the envelopes is red is 1/9 (simplified) or 9/81.
Step-by-step explanation:
There are a total of 9 envelopes. If two are selected at random with replacement the probability for both envelopes is 3 / 9 or 1/3. Since there are two you would do 1/3 * 1/3 to get 1/9 or 3/9 * 3/9 to get 9/81.

please help i’m not tryna fail algebra i can’t figure this out(solve by substitution and show steps please)
Answer:
y=8-6x
Step-by-step explanation:
Answer:
y=0
x=4/3
Step-by-step explanation:
6x+y=8
x =8-y/6
substitute 8-y/6 in second equation
42*8-y/6 +7y=56
7(8-y) +7y=56
56-y+ 7y=56
-y+ 7y=0
6y=0
y=0
6x+y=8
6x+0=8
x=8/6
x=4/3
ill give u the crown thingy pls help
Answer:
y=18 x=15
Step-by-step explanation:
1.
multiplyboth sides by 3
2(x-6)=18
divide both sides by 2
x-6= 9
add 6 on both sides
x=15
2.
add 6 on both sides
2/3y= 12
multiply both sides by 3
2y=36
divide both sides by 2
y=18
Helpppppo plsssss!!!!!!!! Thank you
44 ÷ 1100
pls show your work thx
Answer:
25 is the answer
for proof see the pic
first divide it by 11 then and when you get the numerator as 100 and denominator as 4 divide it by 2
So as to get numerator as 50 and denominator as 2 .
Later, Divide it by 2 and hence, your answer is 25.....;)

The area of a triangle is 2x^2 - 11x + 15 square meters. The length of the base of the triangle is 2x-5
meters. What is the height of the triangle?
Answer:
of triangle =12base×height
Area of triangle =2x2−11x+15
base =2x−5
Plugging in the given;
2x2−11x+15=12(2x−5)×height
2x2−11x+15=2x−52×height
2x2−11x+151=2x−52×height
2(2x2−11x+15)=(2x−5)×height
4x2−22x+30=(2x−5)×height
4x2−22x+302x−5=height
Resolving the quadratic equation;
(4x2−22x+30)
Simplifying;
4x
Answer:
2x-6
Step-by-step explanation:
height : 2(2x^2-11x+15)/(2x-5)
(4x^2-22x+30)/(2x-5)
Δ/4 = 121 - 120 = 1
x1 = (11+1)/4 = 3
x2 = (11-1)/ 4 = 5/2
4(x-5/2)(x-3)
(4x-10)(x-3)/(2x-5)
2(2x-5)(x-3)/(2x-5)
2x-6
Proof
(2x-6)(2x-5)/2
2(x-3)(2x-5)/2
2x^2-5x-6x+15
2x^2-11x + 15

Consider this cone.
A cone with radius 4 and slant height of l.
Which statements about finding the surface area of the cone are true? Check all that apply.
The surface area is the sum of the lateral area and the base area.
The slant height is the distance from the center of the circular base to the vertex.
The lateral area is the area of the curved surface of the cone.
The lateral area can be found using the equation LA = Pirl.
The base area can be found using the equation B = r2.
Please dont answer unless you know it. Edge 2021.
Answer:
1)The surface area is the sum of the lateral area and the base area.

Answer:
The slope is 3
Step-by-step explanation:
m = rise/run
m = (y2 - y1)/(x2-x1)
points: (0,-5), (1,-2)
m = ((-5) - (-2))/ ((0) - (1))
m = (-5 + 2)/ (-1)
m = -3/-1
m = 3

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆
Answer:
240
Step-by-step explanation:
1/5
0.75 = 3/4
1/5 + 3/4 = 19/ 20
1 - 19/20 = 1/20
therefore 12 mango equal 1/20
12 × 20 = 240
12/240 is the same as 1/20
