Answer: 13
Step-by-step explanation:
The formula for finding distance between two points is given by :
D = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]x_{1}[/tex] = -4
[tex]x_{2}[/tex] = 1
[tex]y_{1}[/tex] = 9
[tex]y_{2}[/tex] = -3
Substituting the values into the formula , we have :
D = [tex]\sqrt{(1 -(-4))^{2} +(-3-9)^{2}}[/tex]
D = [tex]\sqrt{(5)^{2}+(-12)^{2}}[/tex]
D = [tex]\sqrt{25+144}[/tex]
D = [tex]\sqrt{169}[/tex]
D = 13
Therefore : the distance between the points is 13

A=1/2bh. A=200ft. H=10. What is b
Answer:
B= [tex]\frac{2A}{H}[/tex]
Step-by-step explanation:
If you noticed, A= [tex]\frac{1}{2}[/tex]BH is the formula for finding the area for a triangle. Your goal is to get B by it's self. Your first step will be to clear of the fraction first, so you will multiply both sides by 2. 2(A)=2([tex]\frac{1}{2}[/tex]BH). On the left, you have 2×A= On the right side, you have 2([tex]\frac{1}{2}[/tex]BH), but since you have a number in the equation, you will only use 2×[tex]\frac{1}{2}[/tex]. To solve 2×[tex]\frac{1}{2}[/tex], you will cnacel out both 2's and you have 1. 1×BH will still equal BH, so you are now left will B×H.
(Your new equation looks like this by the way). 2A=BH
Since you need to get B by its self, the way to clear the H away from the B is by dividing. You will now divide the B and H aswell as 2A and H. (It will look like this) [tex]\frac{2A}{H} = \frac{BxH}{H}[/tex] . (Again when you have the same number or letter, you cross it out. When you divide, you won't change anything on the left side, and all you have to do on the right id to cross out the H next to the B and cross out the H on the bottom of the equation). You should be left with [tex]\frac{2A}{H}[/tex] = B. Now you can turn it around for your final answer. B= [tex]\frac{2A}{H}[/tex].

It takes 54 minutes for 4 people to paint 6 walls. How many minuets does it take 6 people to paint 7 walls?
It takes 42 minutes for 6 people to paint 7 walls
Solution:
It takes 54 minutes for 4 people to paint 6 walls
To find: Minutes required for 6 people to paint 7 walls
If [tex]M_1[/tex] men can do [tex]W_1[/tex] work in [tex]D_1[/tex] days working [tex]H_1[/tex] hours per day and [tex]M_2[/tex] men can do [tex]W_2[/tex] work in [tex]D_2[/tex] days working [tex]H_2[/tex] hours per day, then
[tex]\frac{M_1D_1H_1}{W_1} = \frac{M_2D_2H_2}{W_2}[/tex]
M = Number of men
D = Number of days
H = Number of hours per day
W = Amount of work
Here in this sum,
54 minutes for 4 people to paint 6 walls
[tex]H_1 = 54 minutes ; M_1 = 4 people ; W_1 = 6 walls[/tex]
Minutes required for 6 people to paint 7 walls
[tex]H_2 = ? ; M_2 = 6 people ; W_2 = 7 walls[/tex]
Substituting the values in formula, we get
[tex]\frac{54 \times 4}{6} = \frac{H_2 \times 6}{7}\\\\9 \times 4 = \frac{H_2 \times 6}{7}\\\\H_2 = \frac{36 \times 7}{6}\\\\H_2 = 42[/tex]
Thus it takes 42 minutes for 6 people to paint 7 walls

DOES IT MAKE SENSE?

9. I read a book that had 10 words in it.
(10. I've seen about 1050 commercials on TV.
11. I work in an office building that is 300 feet high.
12. In total, Americans spend about a billion dollars per year on
housing costs (rent and home mortgage payments).
13)A popular local restaurant serves 5 million dinners each year.
14)The CEO of the company earned more money last year than
the company's 500 lowest-paid employees combined.
This answer evaluates each statement for its potential truthfulness, noting that while each could arguably be correct, they might also be inaccurate in certain contexts.
Explanation:It's tricky to definitively state whether these statements are true or false without further context, as they contain details that could conceivably be true but may also potentially be inaccurate.
I read a book that had 10 words in it. This could be possible, especially for children's books or minimalist concept books. I've seen about 1050 commercials on TV. This might be true or not, considering that a person who watches television regularly could have seen this number of commercials. I work in an office building that is 300 feet high. This statement is plausible, given there are many buildings of this height. In total, Americans spend about a billion dollars per year on housing costs (rent and home mortgage payments). This is probably true since the American housing market is extensive. A popular local restaurant serves 5 million dinners each year. This is a high number, but it could be true for a very popular or large restaurant. The CEO of the company earned more money last year than the company's 500 lowest-paid employees combined. Sadly, this could be true given the substantial wage gaps that can exist in companies.

A. 16
B. 10
C. 8
D. 4
Answer:
4 feet
Step-by-step explanation:
From the question, we are given;
Height of the cylinder as 20 ft Volume of the cylinder as 320 piWe are required to find the radius of the cylinder fish tank;
We need to know that the volume of a cylinder is given by;Volume = pi × r² × h
Rearranging the formula;
r² = V ÷ pi × h
Therefore;
r² = 320 pi ÷ (pi × 20 ft)
= 16
Thus;
r = √16
= 4 ft
Therefore, the radius of the fish tank is 4 feet.

Step-by-step explanation:
The decimal number 0.0014 can be written in standard form (also known as scientific notation) as 1.4 x 10^-3. This is done by shifting the decimal place so that you have a number between 1 and 10, and then indicating how many places you moved the decimal in the exponent of ten.
Explanation:The student asked to convert the decimal 0.0014 into standard form. The standard form for representing decimal numbers involves using the scientific notation which means expressing numbers as a number between 1 and 10, multiplied by the power of ten. So, 0.0014 can be written as 1.4 x 10^-3 in standard form.
This can be done through the following steps:
Decide where the decimal point needs to be for the number to be between 1 and 10. In this case, 1.4.Count how many places you had to move the decimal to get this number. In this case, 3 places.If you moved the decimal to the right, it's a negative exponent. If to the left, a positive exponent. Here, we moved right, so it's a negative exponent.In the final step, write this number times ten, raised to the power of the number of places you moved the decimal.

Step-by-step explanation:
Question 1:
Amount to be spend = $625
Cost to rent the ball room for 3 hrs = $350
Cost of each additional hour = $125
Ms Jensen wrote the Inequality as,
[tex]625>350+125h[/tex]
h⇒ Number of additional hours.
We need to find the value of 'h'.
Solution:
[tex]625>350+125h[/tex]
Now Subtracting both side by 350 using subtraction property of Inequality we get;
[tex]625-350>350+125h-350\\\\275>125h[/tex]
Dividing both side by 125 using Division property of Inequality we get;
[tex]\frac{275}{125}>\frac{125h}{125}\\\\2.2>h[/tex]
Hence The value of 'h =2' make the Inequality true.
Question 1:

For his coffee shop, Abdul wants to make a mocha-java blend that will sell for $18/kg. The mocha coffee beans sell for $20/kg, and the java coffee beans sell for $15/kg. How many kilograms of each kind of coffee bean should he use to make 50 kg of the mocha-java blend?
30 kg of mocha coffee bean and 20 kg of java coffee bean should be used to make 50 kg of mocha java blend that will sell for $ 18 per kg
Solution:
Let "x" be the kilogram of mocha coffee beans
Let "y" be the kilogram of java coffee beans
Cost of 1 kg of mocha coffee bean = $ 20
Cost of 1 kg of java coffee bean = $ 15
Kilograms of each kind of coffee bean should he use to make 50 kg of the mocha-java blend
Cost of 1 kg of mocha java blend = $ 18
From given information,
Mocha coffee beans and java coffee beans are mixed to get 50 kg of blend
Therefore,
[tex]x + y = 50 ------------ eqn 1[/tex]
Abdul wants to make a mocha-java blend that will sell for $18/kg
Therefore, we frame a equation as:
(kilogram of mocha coffee beans) x (Cost of 1 kg of mocha coffee bean) + (kilogram of java coffee beans) x (Cost of 1 kg of java coffee bean) = Cost of 1 kg of mocha java blend x 50 kg
Thus we get,
[tex]x \times 20 + y \times 15 = 18 \times 50\\\\20x+15y = 900 ------------ eqn 2[/tex]
Let us solve eqn 1 and eqn 2
From eqn 1,
x = 50 - y -------- eqn 3
Substitute eqn 3 in eqn 2
20(50 - y) + 15y = 900
1000 - 20y + 15y = 900
5y = 100
y = 20Substitute y = 20 in eqn 3
x = 50 - 20
x = 30Thus 30 kg of mocha coffee bean and 20 kg of java coffee bean should be used to make 50 kg of mocha java blend that will sell for $ 18 per kg
We need to set and solve a system of equations, with the variables representing the weights of mocha and java coffee in the blend. Solving the system yields the number of kilograms needed.
Explanation:To solve your problem, Abdul, we will use the concept of weighted averages. We'll need two equations. Let's denote the weight of the mocha coffee in the mix by x kg and the weight of java coffee by y kg. From the problem's requirements, we get these two equations:
x + y = 5020x + 15y = 18*50.Now, the goal is to solve this system of equations. You can do that by, for example, substituting x = 50 - y in the second equation and solving for y. Then, substitute y's value back into the first equation to get x.
The solution to this system will give you the weights of mocha and java coffee beans needed to make your desired blend.
