hello there mate
Step-by-step explanation:
write a expression that represents the height of a tree that begins at 8 feet and increases by 2 feet per year. Let t represent the number of years. How tall will the tree be in 5 years?
Answer:
8 + 2t
In five years, 18 feet
Answer:
8 + 2(t)
Step-by-step explanation:
8 is the initial height of the tree, and 2 represents the growth per year, and each year is calculating by represnting each year as (t), so
ex.
2 years pass
8 + 2(2) = 8 + 4 = 12ft
2ft per year, 2 years = 4

Answer: It may possibly be SU
Step-by-step explanation:
Answer:
SU
Step-by-step explanation:
The triangles are reflections of each other (the same but mirrored).
So if you trace a line from point D to F, and do the mirrored motion on the other triangle, you get SU
An orange cone has an
exact volume of 1207T ft3.
What is the height of the
cone if the radius is 6 ft?
Answer:
32.01 ft
Step-by-step explanation:
Step one:
given data
Volume of 1207T ft3.
the radius is 6 ft
Step two:
The volume of a cone is given as
[tex]V=1/3 \pi r^2h[/tex]
substitute
1207= 1/3*3.142*6^2*h
1207= 37.704h
divide both sides by 37.704
1207/37.704= h
h= 32.01 ft

Write the equation of the line with the given slope and y intercept
m = -5 b = -8
Answer:
y = -5x -8
Step-by-step explanation:
The equation is y = mx + b so just plug it all in
y = -5x + (-8)
which is
y = -5x -8
2x+3y=4 y+3x=6
find x and y
Answer:
x=-3/2y+2
y= y=−3x+6
Step-by-step explanation:
solve for x.
2x+3y=4
Add -3y to both sides.
2x+3y+−3y=4+−3y
2x=−3y+4
Divide both sides by 2.
2x/2= -3+4/2
x= -3/2 y+2
solve for y.
y+3x=6
Add -3x to both sides.
3x+y+−3x=6+−3x
y=−3x+6
calculate the rise and run to find the slope of the line
Answer:
3
Step-by-step explanation:
To find the slope of the line, you can use the formula rise/run.
Every time the graph moves one unit across the x-axis, it moves three spaces up. Therefore,
Rise = 3
Run = 1
Now to plug this into our formula:
3/1 = 3
The slope of the line is 3.
Express in the form
n:1
.
Give n as a fully simplified fraction.
8:6
Answer:
4/3 : 1
Step-by-step explanation:
Here, we want to express 8:6 in the form n:1
All we have to do is to divide both ratio sides by 6
That would be;
8/6 : 6/6
= 4/3:1

Step-by-step explanation:
Simplify: c5•c3•c3
a) C45
b) 3c11
c) C11
d) None of the above
Answer: C
Step-by-step explanation:
I assume you mean c to the power 5, c to the power 3, and c to the power 3. Well, c^5xc^3xc^3 is c^11. Here's why. When multiple terms that have exponents in them and have the same base are multiplied, you just have to add the exponents. Here's the logic behind this (I'm using another example). If you have 6^3x6^5, your answer will be 6^8 because this can be rewritten as (6x6x6)x(6x6x6x6x6). This is the same thing as 6^8. So, I hope this made sense and your answer will be c.
The requried, simplified expression of [tex]c^5 * c^3 * c^3[/tex] is [tex]c^{11}[/tex]. Option C is correct.
When we have a multiplication of powers with the same base, we can apply the rule of exponents that states: when multiplying powers with the same base, we add their exponents.
In this case, the base is 'c', and we have three terms: c^5, c^3, and c^3. To simplify the expression, we add the exponents:
[tex]c^5 * c^3 * c^3 = c^{5+3+3} = c^{11}[/tex]
So, the simplified form of the expression [tex]c^5 * c^3 * c^3[/tex] is [tex]c^{11}[/tex].
In option b) [tex]3c^{11}[/tex], the coefficient of '3' indicates that we have three terms of [tex]c^{11}[/tex], which is not the case in the original expression.
Therefore, the correct answer is c) [tex]c^{11}[/tex], as we simplified the expression to a single term with the base 'c' raised to the power of 11.

A microscope was originally priced at $100 but went on sale for 10% off. If Adele bought the microscope and paid 10% sales tax, how much did she pay in total?
Answer:
$99
Step-by-step explanation:
First, it was on sale for 10% off. 10% = 0.1 = 1/10. 1/10 of 100 is 10, so we subtract 10 (because 10% off) to get $90. Then, the sales tax, which we add, is 10%. 1/10 of 90 is 9, so we add 9 to 90 to get our total to be $99
(-10,-7) (-8,1) find the distance between two points
Answer: [tex]\sqrt{68}[/tex] units.
Step-by-step explanation:
The distance between points (a, b) and (c, d) is given by :_
[tex]D=\sqrt{(d-b)^2+(c-a)^2}[/tex]
Given points : (-10,-7) (-8,1)
Distance between points (-10,-7) and (-8,1) = [tex]\sqrt{(1-(-7))^2+(-8-(-10))^2}[/tex]
[tex]=\sqrt{(1+7)^2+(-8+10)^2}\\\\=\sqrt{8^2+2^2}\\\\=\sqrt{64+4}\\\\=\sqrt{68}[/tex]
Hence, distance between given points = [tex]\sqrt{68}[/tex] units.

A baseball player reaches first base 3 out of 10 times he is at bat. If the baseball player bats 80 times, about how many times will the player reach first base?
Answer:
I think the answer is 24.
Step-by-step explanation:
I think the answer is 24 because if the baseball player hit the bat and ran the base 3 out of 10 times, then you would multiply 8 x 3 to get 24 out of 80. I don't know if this is the correct answer, this is just what I think it may be.
