questions in the pics i have sent
Answer:
Step-by-step explanation:
Picture 1
In right triangle ABC,
Side AB is the opposite side of angle C.
Picture 2
In triangle MKL,
tan(∠M) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{KL}{KM}[/tex]
= [tex]\frac{15}{8}[/tex]
Option (1) is the answer.
Picture 3
In ΔXYZ,
sin(∠Z) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{XY}{XZ}[/tex]
For the length of XY we will apply Pythagoras theorem in ΔXYZ,
XZ² = XY² + YZ²
XY² = XZ² - YZ²
= (40)² - (32)²
XY = √576
= 24
sin(Z) = [tex]\frac{24}{40}[/tex]
sin(Z) = [tex]\frac{3}{5}[/tex]
Picture 4
In right triangle DEF,
Cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{EF}{DF}[/tex]
= [tex]\frac{75}{72}[/tex]
= [tex]\frac{25}{24}[/tex]
Picture 5
In ΔABC,
tan(63°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(63°) = [tex]\frac{BC}{AB}[/tex]
AB = [tex]\frac{BC}{\text{tan}(63)}[/tex]
AB = [tex]\frac{8}{\text{tan}(63)}[/tex]
AB = 4.0762 ≈ 4 m
Option (3) will be the answer.
if the diameter of a circle is 65 what is the area
Answer:
(4225/4)pi units^2
Step-by-step explanation:
So we need to know the area of a circle formula to find the answer to this question
the formula is A = r^2(pi)
So we have the diameter but we need the radius. The radius is half the diameter so r = 65/2
Now we can plug the radius into the area formula
(65/2)^2*pi =
(4225/4)pi units^2

Step-by-step explanation:
The number of bacteria on a piece of toast triples every
hour. If there is only one bacteria cell now, how many
will there be in 24 hours?
HELP PLZZZ WILL MARK BRAINLIEST!!!
Answer:
You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.
Next hour, it triples again so you now have 1 x 3 x 3=9
You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).
Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:
n x 324 where n is the number of bacteria you begin with.
Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer
List three factors that must be considered when designing and building a house? Describe how each factor can influence the design and the building of the house.
I will be giving brainiest to correct and best explained answer! :)
Step-by-step explanation:
I would say the area its getting built. imagine wanting to build a house but you can't dig the sewer (if thats the spelling) pipes bc the area you want doesn't have any water or something like that. definitely money. without it, you can't do anything, you can't buy materials or even hire people to help you because you cannot tell me that you can build a house on your own. Another I would say is Labor cause like I said, if you ain't got nobody to help you, you're probably going to take a few years or more. so if you want to build a house in an area where there is a few architects and designers, you're just going to have to suck it up and get what you get.

Find the value of x in this proportion.
621=10x
Answer:
x = 62.1
Step-by-step explanation:
Note the equal sign in this equation, what you do to one side, you do to the other. Isolate the variable, x, by dividing 10 from both sides of the equation:
[tex]621 = 10x\\\\\frac{621}{10} = \frac{10x}{10} \\\\x = \frac{621}{10} \\x = 62.1[/tex]
Answer:
x = 62.1

Answer:
2 9/14
Step-by-step explanation:
first we must make 1/6 and 3/7 have common demoniaters! (or however u spell it)
1/6 x 7/7 = 7/42
3/7 x 6/6 = 18/42
7/42 + 18/42 = 25/42
2/7 x 6/6 = 12/42
25/42 + 12/42 = 37/42
37/42 + 7/42 = 44/42
44/42 + 18/42 = 62/42
62/42 + 12/42 = 74/42
5/7 x 6/6 = 30/42
74/42 + 30/42 = 104/42
104/42+7/42 = 111/42
111/42 = 2 9/14

Sean runs 2/3 of a mile in 10 minutes. at this rate, how many miles can Sean run in 30 minutes? Explain how you found this answer. Please I need it quick!
Answer:
2 miles.
Step-by-step explanation:
In this case, we would multiply the numerator by 3 since we know that it takes him 10 minutes to run 2/3 of a mile. So, 2x3 = 6. Which gives us 6/3. Simplified that would be 2 miles. Hope this helps!

Answer:
IQR = 10
Step-by-step explanation:
1. Find the median (middle data point.)
2. Find the median of the upper quartile (70 - 80.)
3. Find the median of the lower quartile. (60 - 70.)
4. Subtract the lower quartile from upper quartile.
1. median of the data = 70
2. median of Q2 = 75
3. median of the Q3 = 65
4. 75 - 65 = 10
IQR = 10

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of campers who voted for hot dogs = 5 campers
Let the number of campers who voted for sphagetti = 4 campers
Now , the total campers = 5 + 4
= 9 campers
5 out of 9 campers vote for hot dogs
So ,
The total number of campers = 72 campers
The equation will be ,
The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72
The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72
= 5 x 8
The total number of campers who voted for hotdogs = 40 campers
Hence , The number of campers who voted for hotdogs is 40 campers
