Answer:
21.33 units (rounded)
Step-by-step explanation:
The height, x, can be determined through the Pythagorean Theorem:
a^2+b^2=c^2 (where b will be our height)
(22/2)^2+b^2=24^2
121+b^2=576
b^2=455
b=21.33072901
So the height is about 21.33 units

5. The largest mosaic in the world is on the walls of the central library of the
Universidad Nacional Autonoma de Mexico in Mexico City. The mosaic depicts
scenes from the nation's history and covers an area of 4000 m2. If the entire
mosaic were on one square wall, what would the dimensions be? Estimate your
answer to the nearest whole number and then use your calculator to get the
length to the nearest HUNDRETH.
Answer:
63.25mStep-by-step explanation:
The area of the square wall = L² where;
L is the length of the wall.
Given
Area of the mosaic = 4000m²
Substitute into the formula and get L
4000 = L²
Square root both sides
√4000 = √L²
√4000 = L
Rearrange
L = √4000
L = 63.25m (to the nearest hundredth)
Hence the length to the nearest hundredth is 63.25ma man earned and interest of 240 in 4 years at 20%per annum simple interest. calculate the principal
Answer:
Step-by-step explanation:
P x 20/100 x 4=240
1/5 x 4p =240
4/5p x5=240 x 5
4p/4=1200/4
p=300
We need I = prt.
240 = p(0.20)(4)
240/[(0.20)(4)] = p
Use your calculator to calculate the left side.

solve what is 1/2 x 15
Answer:
7.5
Step-by-step explanation:
it's basically just 15 divided by 2
The equivalent value of the expression (1/2 x 15) is 7.5.
What is algebraic expression?In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations.
Given is to solve the expression as -
1/2 x 15
We can write the expression as -
{x} = 1/2 x 15
{x} = 15/2
{x} = 7.5 x 2/2
{x} = 7.5

Zayd can row 3/8 of a mile in 1/4 of an hour. What is the unit rate the describes the miles per hour?
Answer:
1.5mph
Step-by-step explanation:
Given parameters:
Distance sailed = [tex]\frac{3}{8}[/tex]miles
Time taken = [tex]\frac{1}{4}[/tex]hr
Unknown:
Unit rate of sail in miles hour = ?
Solution:
This is also the speed of the sail. It is the distance divided by time taken.
Speed = [tex]\frac{distance}{time}[/tex]
Speed = [tex]\frac{\frac{3}{8} }{\frac{1}{4} }[/tex]
Speed = [tex]\frac{3}{8}[/tex] x 4 = 1.5mph

the equation of the line that has a slope of
-23 that passes through the point (5, 1). Which form did you choose to write the equation in and why?
Answer:
I used the y=Mx+b equation because it has a good job showing each of the elements in the equation.
Step-by-step explanation:
The slope is -2/3 so if you add it to (5,1) it would be (3,4) as you just add three and subtract to to the point. I’m going to use for this equation as it is more simple and it gives a good job showing what each element is in the equation. M is the slope, so now we have y= -2/3x +b. To find b, substitute x and y for a point on this line which I will use the point (3,4) for. Now, multiply -2/3 by 3 and you will get -2 after. Now you have 4=-2+b which the answer would be 6.
This is just an example of finding the equation, which form I used, and why.
