Step-by-step explanation:
a tree that is 13 feet tall is growing at a rate of 4 feet each year. A different tree that is 27 feet tall is growing at a rate of 1/2 feet each year. At this rate, when will the trees be the same height? What will the height of the trees be?
(Also I need help before 3 pm it’s 1:21 pm btw) PLEASE HELP
Answer:
Step-by-step explanation:
After t years,
the first tree will be 13+4t feet tall
the second tree will be 27+½t feet tall.
When they are the same height,
13+4t = 27+½t
subtract ½t from both sides
13+3½t = 27
subtract 13 from both sides
3½t = 14
divide both sides by 3½
t = 14÷(3½) = 14÷(7/2) = 14× (2/7) = 4
The trees will be the same height in 4 years.

Kai calculates that he spends 15% of a
school day in science class. If he spends
75 minutes in science class, how many
minutes does Kai spend in school?
Answer-
Kai spends 8 hours 20 minutes in school.
Solution-
Let us assume, Kai spends x minutes in school.
Kai calculates that he spends 15% of a school day in science class and that is 75 minutes, i.e
\Rightarrow x\times \dfrac{15}{100}=75⇒x×
100
15
=75
\Rightarrow x=75\times \dfrac{100}{15}⇒x=75×
15
100
\Rightarrow x=\dfrac{7500}{15}⇒x=
15
7500
\Rightarrow x=500\ \text{minutes}⇒x=500 minutes
\Rightarrow x=\dfrac{500}{60}\ \text{hours}⇒x=

\Rightarrow x=\dfrac{25}{3}\ \text{hours}⇒x=

12 = 3(m - 17)
Help please. You have to use distributive property to solve.
Answer:
m = 21
Step-by-step explanation:
12 = 3(m - 17)
12 = 3m - 51 (Found using the distributive property)
63 = 3m (Found by adding 51 to both sides)
21 = m (Found by dividing both sides by 3)

A gardener is planting two types of trees: Type A is 36 inches tall and grows at a rate of 15 inches per year. Type B is 48 inches tall and grows at a rate of 10 inches per year. a. Model the situation as a system of linear equations. Use x to represent the number of year and y to represent the height of each tree. b. Determine exactly how many years it will take for these trees to be the same height. You can check in Desmos for the answer, but you must show all algebraic work. c. What is the height of the tree at that point?
Answer:
A.
type A: Y= 15x +36
type B: Y= 10x + 48
B.
15x +36= 10x+48

How much solutions does this equation have?
2x+y=3
2y=-4x+6
pls answer,, show ur work, have a great day :)) !!
Answer:
All solutions or infinite.
Step-by-step explanation:
Turn 2y = -4x + 6 into standard form - divide by 2
Y = -2x + 3
2x + y = 3
Substitute the y equation in for y.
2x - 2x + 3 = 3
The x variables cancel out.
3 = 3
Which is true so it means all solutions.

Jack chooses two numbers between 50 and 150
The two numbers have a Lowest Common Multiple (LCM) of 420
They have a Highest Common Factor (HCF) of 28
Work out what the two numbers are.
Answer:
84 and 140
Step-by-step explanation:
Jack chooses two numbers between 50 and 150
The two numbers have a Lowest Common Multiple (LCM) of 420
Factors of 420 between 50 to 150
= 60, 70, 84, 105, 140
We are also told that:
They have a Highest Common Factor (HCF) of 28
Hence, we find out of the factors above, which numbers can be divided by 28 without having any remainder.
60/28 = 2.1428571429
70/28 = 2.5
84/28 = 3
105/28 = 3.75
140/28 = 5
Therefore, the two numbers are
84 and 140

The students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining. The table shows the number of carrots remaining after different amounts of time. Which snack did the students eat at a faster rate? Explain.
Answer:
Grapes
Step-by-step explanation:
The rate of change for the grapes was -12 grapes per minute.
To calculate the rate of change for the carrots, use the slope formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex]. In this case, m is the rate of change, time is x, and the carrots remaining is y.
[tex]m = \frac{118-136}{8-6} = \frac{-18}{2} = -9[/tex]
The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.
If the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that, the students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining.
Grapes were changing at a pace of -12 grapes per minute. Use the slope formula to get the rate of change for the carrots.
m=118-136/8-6
m=-18/2
m=-9
The students consumed the grapes more quickly because the decline in grapes was significantly larger than the decline in carrots.
Thus, the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.

Find the cost of 4.8 kilograms of potatoes at the price of $0.75 a
kilogram?
Answer: $3.60
Step-by-step explanation:
If you need 4.8 kilograms of potatoes and each kilograms costs $0.75, then we should multiply 0.75 by 4.8 to find the cost of 4.8 kilograms of potatoes.
4.8 x 0.75 = 3.6.
Therefore, the cost of 4.8 kilograms is $3.60 dollars. I hope this helps, and good luck!
The price of gasoline rose from $2.40 to $2.76 in one month. By what percent did the gas price rise?
Answer: 15%
Reason: I wrote it down hopes it helps!!
The percent of increase of any quantity is the ratio of the change in the value of that quantity to the initial value of the quantity. The gas price rose by 15%.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The initial price of gasoline = $2.40
The final price of gasoline = $2.76
Thus, change in the price = $2.76 - $2.40
= $0.36
Now, the percentage increase of price is given by,
(change in the price ÷ initial price) × 100
= (0.36 ÷ 2.40) × 100
= (3 / 20) × 100
= 15
Hence, the percent increase in the price is given by 15%.

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 5 to 2. If he wants to use a total of 126 cans, how many cans of green beans should he use?
please help me lol
Answer:
90 pumpkin and 36 green beans
Step-by-step explanation:
Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.
Answer:
9 cans
Step-by-step explanation:
126/7=18
18/2=9
so 9 is the answer

What is the area of the following circle?
Answer:
78.53
Step-by-step explanation:
[tex]\pi[/tex] x [tex]5^{2}[/tex]
Answer:
78.5
Step-by-step explanation:
The formula for the area of a circle is A=πr^2. The radius, (r) is half of the diameter. The diameter of this circle is 10 in, so the radius is 5 in. Plug 5 into the formula A=πr^2 to get A=π5^2. Square 5 to get 25 and plug it back in the formula to have A=25π. Multiply pi (π, 3.14) by 25 to get 78.5.

Colton owns a food truck that sells tacos and burritos. He only has enough supplies to make 120 tacos or burritos. He sells each taco for $3.75 and each burrito for $6. Colton must sell at least $540 worth of tacos and burritos each day. If xx represents the number of tacos sold and yy represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
Inequality 1) y≤120−x; shade down
Inequality 2) y≥90−0.625x; shade up
Possible solution: (10,100)
*Colton could sell 10 tacos and 100 burritos.
Step-by-step explanation:
Hope I helped ^u^
Colton can sell 20 tacos and 100 burritos.
What is inequality?An inequality is a relation between two numbers or expressions that are not equal. It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.
Given that, Colton can make 120 tacos or burritos in total, the taco for $3.75 and each burrito for $6, He must sell at least $540 worth of tacos and burritos each day,
Establishing the inequality,
x + y ≤ 120............(i)
3.75x + 6y ≥ 540
0.625x + y ≥ 90...........(ii)
Plotting the graph, the solution will be the portion covered by both the inequality.
One of the possible solution is = (20,100)
Hence, Colton can sell 20 tacos and 100 burritos.
