Answer:
70 years
Step-by-step explanation:
28 cm more to reach 1 meter (100 cm)
28 cm / 4 mm/year =
280 mm / 4mm/year = 70 years
A tank can be filled in 22 and a fifth minutes. What fraction of it will be filled in 21 min
Answer:
I believe the answer is about 95 percent.
Step-by-step explanation:
The reason for this answer is because as said 22 and a fifth would mean the tank is full. This means I set up a proportion. What I did was...
22 1/5 over 100 = 21 over x
Now: I do 21 multiply by 100 divided by 22 1/5 to get the answer
What I just wrote is the rule of proportions
Finally, after doing all of that, the answer I got was 94.59459459, but I rounded to the answer of 92 percent.

You scored 57 points on your math quiz. the correct answer would be an option (D).
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
You scored a 95% on your math quiz.
You have to determine the evaluation of 95% of 60.
⇒ 95% of 60
95% is expressed as 15/100 in fractional form
⇒ (15/100)(60)
95/100 is expressed as 0.95 in decimal form
⇒ (0.95)(60)
Apply the multiplication operation, and we get
⇒ 57
Therefore, 95% of 60 would be 57.

Vera claimed the solution set on the number line represents the inequality Negative 78.9999 greater-than-or-equal-to x.
A number line going from negative 83 to negative 77. A closed circle is at negative 79. Everything to the left of the circle is shaded.
Which error did Vera make?
Vera wrote the inequality with the variable on the left side of the relation symbol.
Vera wrote a relation symbol that does not represent the direction of the ray.
Vera selected an inequality that does not include –79 in its solution set.
Vera used the wrong number in her inequality.
So basically, we have [-83, -77] as the whole thing.
There's a circle that limits [-83, -79) as a shaded zone.
Vera claims that -78.9999 [tex]\geq[/tex] X, which is false.
Vera wrote a relation symbol that doesn't represent the ray's direction. She went the other way around.

Answer:
The perimeter is 380 ft^2.
Step-by-step explanation:
To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.
To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.
Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

5. SereN and Visala had a combined total of $180. SereN then gave Visala $20, and then Visala gave SereN a quarter of the money Visala had. After this, they each had the same amount. How much money did SereN start with?
The amount of money seren had will be $132.
what is a linear equation?
It is defined as the linear relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
Seren and Visala had a combined total of $180Seren then gave Visala $20, and then Visala gave Seren a quarter of the money Visala had. After this, they each had the same amount.
The solution will be done by making an equation:-
According to the first condition:-
S + V = $180
Now from the second condition:-
S - 20 + { ( v + 20 ) / 4 ) } = 180
Since S = v then:-
S - 20 + { ( S + 20 ) / 4 ) } = 180
S = $132
Therefore the amount of money seren had will be $132.

Will give brainly for correct answer!!!! 30pts
Answer:
We are given a perimeter and three different lengths and we need to determine the corresponding width and area.
The first length that is provided is 2 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(2 + 6) which gives us a perimeter of 16 feet and a width of 6 feet. We can then get the area by multiplying the length by width which gives us 12 feet squared.
The second length that is given is 4 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(4 + 4) which gives us a perimeter of 16 feet and a width of 4 feet. We can then get the area by multiplying the length by width which gives us 16 feet squared.
The final length that is given is 5 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(5 + 3) which gives us a perimeter of 16 feet and a width of 3 feet. We can then get the area by multiplying the length by width which gives us 15 feet squared.
Therefore, the field that would require the most amount of paint (the largest area) is option B, region #2.

What is the area, in square meters, of the trapezoid below?
Answer: 94.54 m^2 (square meters)
Step-by-step explanation: The formula for the area of a trapezoid is A = 1/2(a+b)h; where a and b are the two top sides of the trapezoid that are parallel. Let us then solve.
Let us combine both sides two maintain the overall side for "b", which is 18 + 5.1 = 23.1
Let us now add both sides (a + b.) 23.1 + 9.5 is 32.6. We can now multiply by the height. 32.6 multiplied by 5.8 is 189.08
We can now divide (or multiply by 1/2), which is 189.08 * 1/2 or 189.08/2 and that equals 94.54.
Step 1
Find the area of the Rectangle in the middle
To find the area, you have to do [tex]Length*Width[/tex]
[tex]9.5*5.8=55.1[/tex]
The area of the Rectangle in the middle is 55.1m²
Step 2
Find the area of the triangle on the right
To find the area of 1 triangle, we have to use the formula show below:
[tex]A=\frac{1}{2}* Base *Height[/tex]
Base = the part on the bottom
Height = How high the triangle is
[tex]A=\frac{1}{2} *5.1*5.8\\=\frac{1}{2} *29.58\\=14.79[/tex]
The area of the triangle on the right is 14.79m²
Step 3
Find the area of the triangle on the left
Using the formula that we used in the last question about finding the area of the triangle, we can find our answer, here is the formula:
[tex]A=\frac{1}{2}* Base *Height[/tex]
Base = the part on the bottom
Height = How high the triangle is
BUT, before finding the area of this part of the triangle, we have to first find the dimensions, we know the height, but we don't know the base, so to find the base, we will subtract 18 by 9.5 to get our base
[tex]18-9.5=8.5[/tex]
So the base of the triangle on the LEFT is 8.5m
NOW, we can find the area of the triangle on the left
[tex]A =\frac{1}{2}* 8.5*5.8\\=\frac{1}{2} *49.3\\=24.65[/tex]
So the area of the triangle on the LEFT is 24.65m²
Step 4
Add up all the areas to get final answer!
The areas of the 3 shapes are...
55.1m²
14.79m²
24.65m²
If we add these numbers up, we get 94.54m²The area of the trapezoid is 94.54m²
