Answer:
1/2 cm
Step-by-step explanation:
the area of the triangle is √3/4cm^2.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Here, given that,
An equilateral triangle with side length 1 cm .
we know,
area of An equilateral triangle
=√3/4×side²
so, the area of the triangle = √3/4×1
=√3/4 cm^2
hence, the area of the triangle is √3/4cm^2.

What si the equation in slope intercept form of the line that passes through the points (-4,2) and (12,6)
Answer:
b = -12
Step-by-step explanation:
In order to find the slope intercept you must first find the slope of the given points.
[tex]-4,2 = 12,6[/tex]
[tex]S=\frac{y2-y1}{x2-x1}[/tex]
Substitute:
[tex]\frac{12--4}{6-2}[/tex]
[tex]12--4=12+4=16[/tex]
[tex]6-2=4[/tex]
[tex]S=\frac{16}{4}[/tex]
Now find the slope intercept
[tex]16\div4=4[/tex]
[tex]SI=y=mx+b[/tex]
Substitute:
[tex]12=4\times6+b[/tex]
Solve:
[tex]4\times6=24[/tex]
[tex]12=24+b[/tex]
Subtract 24 on both sides:
[tex]12-24=-12[/tex]
[tex]x=-12[/tex]
[tex]y=-12[/tex]

A fish tank contains 600 gallons of water when full. The tank
contains a permanent hole, which causes the tank to leak at a
constant rate of 12 gallons each week. Let w be the number of
weeks. Which of the following expressions describe the number of
gallons left in the tank after any given number of weeks.
a. 600 + 12w
b. 600 - 12w
c. 12 -600w
d. 12 + 600w
Answer: 600 - 12w
Step-by-step explanation:
From the question, we are informed that a fish tank contains 600 gallons of water when full and that the tank
contains a permanent hole, which causes the tank to leak at a constant rate of 12 gallons each week.
If the number of weeks is represented by w, then the expression that describe the number of gallons left in the tank after any given number of weeks will be:
= 600 - 12w
For example let's say the number of weeks is 5 weeks. Using the expression,
600 - 12w
= 600 - 12(5)
= 600 - 60
= 540 gallons
There'll be 540 gallons after 5 weeks.
v=r-s/2 solve for r
Answer:
r=v + [tex]\frac{s}{2}[/tex]
Step-by-step explanation:
v=r-[tex]\frac{s}{2}[/tex]
v+[tex]\frac{s}{2}[/tex]=r
On solving for r, we get -
[tex]$r=v+\frac{s}{2}[/tex]
We have the following expression -
[tex]$v=r-\frac{s}{2}[/tex]
We have to solve for r.
Solve for x (at k = 2) :log ( [tex]\frac{\pi }{x}[/tex] ) = k
On solving -
log(π) - log(x) = k
log(x) = k - log(π)
log(x) = 2 - log(π)
log(x) = 2 - 0.497
log(x) = 1.503
x = 31.84
According to the question, we have -
[tex]$v=r-\frac{s}{2}[/tex]
On solving for r, we get -
[tex]$r=v+\frac{s}{2}[/tex]
Hence, we get - [tex]$r=v+\frac{s}{2}[/tex].

I was constructing towers as you see below. I noticed that each
time I made the tower higher, I had to add more blocks on the
sides to stabilize the structure. I would like to know how many
cubes I will need to build a 5-block high tower and a 10-block
high tower. Generalize, if you can, on how many blocks I will
need for any size tower?
Answer:
is there an equation for this or simple math?
Answer:
5 Blocks=4 blocks (on sides) 10 Blocks=9 blocks (on sides)

You subtract one set of blocks (on sides) each time. That's it! Hope this helps!
Keith decided to do pushups everyday as part of his exercise routine. He started to do 10 pushups today and he will be adding 3 additional counts for each day that his exercise continues. How many pushups will Keith do if he is exactly on his 3rd week of his exercise routine?
Answer:
55 push ups
Step-by-step explanation:
Given that:
Starting count = 10
Additional count = 3
Starting count + (additional count * number of days)
Exactly on the 3rd week = on the 15th day
10 + (3 * 15)
10 + 45
= 55 push ups

What lever has resistance between the axis (fulcrum) and the force (effort)? A. first B. second C. third D. fourth Please select the best answer from the choices provided. A B C D
Answer:
B. Second
Step-by-step explanation:
Levers are defined as the simple machine, which consists of a rod fixed at a pivot, load, and fulcrum. The levers are classified into first class, second, and third class.
What is lever?A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever.
here, we have,
The difference between different types of levers are:
1. In the first-class levers, the fulcrum is present between the load and effort. The mechanical advantage can be greater, less, or equal to 1.
2. The second class levers, the load is present between the fulcrum and effort. The mechanical advantage is always greater than the 1.
3. The third class levers, the effort is present between the fulcrum and load. The mechanical advantage is always less than 1.
Thus, the correct answer is Option 1.

Math often shows up in sports in ways that we don’t realize. Take for example the baseball diamond. It is actually a square with the bases set at a 90 degree angles. If the bases are 90 feet apart, how far is it from home plate to second base? Round to the nearest tenth.
Distance between home plate and second base: ____________________ feet
Group of answer choices
90
127.3
63.6

Answer:
Distance between home plate and second base = 127.3 ft (Approx)
Step-by-step explanation:
Given:
Base distance = 90 ft
Find:
Distance between home plate and second base
Computation:
Distance between home plate and second base = √90²+90²
Distance between home plate and second base = √8100 + 8100
Distance between home plate and second base = √16200

Which is greater, 4 4/10 or 32/10? Explain how u know.
Answer:
4 4/10
Step-by-step explanation:
Well, 32/10 would by 3 2/10 when you divide it, I think. So 4 4/10 is greater.
Fractions may be equal or unequal.
[tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]
The fractions are given as:
[tex]\mathbf{F_1 = 4\frac{4}{10}}[/tex]
[tex]\mathbf{F_2 = \frac{32}{10}}[/tex]
Express the fractions as improper fractions
[tex]\mathbf{F_1 = \frac{44}{10}}[/tex]
Both fractions have the same denominator.
So, the fraction with a greater numerator is greater.
By comparison: 44 is greater than 32
i.e. 44 > 32
Hence, [tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]

Which of the following values of x make the following functions equal? y =4x+6 and y=5x+3
3
2
4
1
Answer:
The value of x that makes both functions. y = 4·x + 6 and y = 5·x + 3 equal is;
x = 3
Step-by-step explanation:
The given functions are;
y = 4·x + 6 and y = 5·x + 3
For the functions to be equal, we have that the y values are equal, therefore;
y = y and 4·x + 6 = 5·x + 3, which gives;
4·x + 6 = 5·x + 3
5·x - 4·x = 6 - 3
∴ x = 3
Therefore, the value of x that makes both functions. y = 4·x + 6 and y = 5·x + 3 equal is x = 3.

Justine lives in an apartment while attending college. Her monthly rent last year was $680, but this year she has to pay $800 per month. By what percent did her monthly rent increase from last year to this year?
Answer:
6,528,000
Step-by-step explanation:
Multiply 800 by 12. Then multiply the number by 680. And there u go.
6,528,000
The percent did monthly rent increase from last year to this year is 17.6%
Last year Justine paid $680 in rent while this year she paid $800 in rent
The increase in rent = $800 - $680 = $120
The percentage increase in rent = ($120/$680) * 100% = 17.6%
The percent did monthly rent increase from last year to this year is 17.6%

What is the solution to the equation -4(2x + 3) = 2x + 6 - (8x + 2)?
A. x = -10
B. x = -8
C. x = - 5/2
D. x = -4/7
Answer:
B. x = -8
Step-by-step explanation:
-4(2x + 3) = 2x + 6 - (8x + 2)
-8x -12 = 2x + 6 - 8x -2
(now, "-8" in both terms is cancelled):
-12 = 2x + 6 - 2
(leave 2x alone in second term):
-12 -6 +2 = 2x
-16 = 2x
-16/2 = x
-8 = x
