Step-by-step explanation:
it is really not complicated. we only need to type the numbers into the calculator.
so, what's the problem ? you don't know what a perimeter is ? it is the circumference, the total way you have to go when waking all around the figure.
you don't know the formulas for the areas of specific figures ?
let's start :
a)
the area of a rectangle is length×width. I hope you know this at least since first grade.
the important thing here is : the result is in² and not just in. it means an area counts the little squares that fill that area.
A = 30×8 = 240 in²
the perimeter, as explained, is the whole way around it. so, in the end, as you can easily see, we would have to go 2 times the long side and 2 times the short side.
the result is in (just a length, a distance not an area, not a cube, ...).
P = 2×30 + 2×8 = 60 + 16 = 76 in
b)
the area of a triangle is
baseline × height / 2
in this case (a right-angled triangle) we can assume one of the sides enclosing the 90 degree angle as baseline and the other as height (since there is already a 90 degree angle between them).
and again, the result is ft². we could express it also e.g. as in², but since the basic measures are in ft, it makes it better understandable to use ft².
A = 12×5/2 = 6×5 = 30 ft²
the perimeter is even easier than for the rectangle, as we have one side less to count.
and as before, we stay with ft.
P = 12 + 13 + 5 = 30 ft
c)
this is the only more special case.
but it is still easy.
the area is baseline × height.
and our unit of measurement here is cm, so the result will be cm².
A = 10×2 = 20 cm²
the perimeter is the same principle as with a regular rectangle, as the angles don't matter. only the side lengths matter.
so, again, while waking around it, we have to pass 2 times the long side and 2 times the short side.
and the result is a length, a distance again, so, it is cm.
P = 2×10 + 2×4 = 20 + 8 = 28 cm
What type of number is the √40?
A Whole number
B. Integer
C. Rational
D. irrational
Select all that apply.
The square root of 40 is a rational number if 40 is a perfect square. It is an irrational number if it is not a perfect square. Since 40 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 40?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.
√40 is an irrational number

Answer:
Rational and Real Number
Please help! There is 2 question! Thank you so much
Answer:
The answers are:
Question 23: 140
Question 24: 25
Step-by-step explanation:
Question 23:
Since 25% is 1/4 of the total amount of members in the club, we need to multiply the amount of drum player (35), by 4.
35 x 4 = 140
Question 24:
The absolute value of -25 is 25, since the absolute value is the value without any signs.
Therefore, the answers are:
Question 23: 140
Question 24: 25

Step-by-step explanation:
5+k/4=3 please explain thoroughly
To solve this equation, you must multiply by a denominator and then subtract to isolate a variable.
Remove the DenominatorMultiply by 4 on both sides of the equation.
[tex]\displaystyle 4(5 + \frac{k}{4}) = 4(3)[/tex]
[tex]\displaystyle 20 + k = 12[/tex]
SimplifySubtract 20 from both sides to isolate the k.
[tex]20 - 20 + k = 12 - 20[/tex]
[tex]\boxed{k = -8}[/tex]
The final answer is k = -8.

i need to know the rest of the equation just letter R
Notice that 2/3 times 12 is...
(2/3)*12 = (2/3)*(12/1)
(2/3)*12 = (2*12)/(3*1)
(2/3)*12 = 24/3
(2/3)*12 = 8
So that explains the 8 on the right hand side.
For the blank, we'll multiply 2/3 by the 9y term like so
(2/3)*9y = ((2/3)*(9/1))y
(2/3)*9y = ((2*9)/(3*1))y
(2/3)*9y = (18/3)y
(2/3)*9y = 6y
This means 6y goes in the blank.
If your teacher only cares about the coefficient, aka number out front of the variable, then you'd just go for 6. That's my guess as to what your teacher wants. It seems to fit with the template you show and that would mean R goes in the second to last slot.

Answer:
The answer is "Each glass of lemonade costs 1 1/2 times the cost of orange juice"
Step-by-step explanation:
The easiest way to figure this out is multiple choice elimination.
For the first option to be true the cost of a glass of lemonade would have to be 3.50 each
For the second option to be true orange juice would have to cost more than lemonade which is not the case
If you solve for the price of the orange juice using the third option the price of orange juice you find, $1, is different than the price of orange juice you are given.
That just leaves the fourth option
If you check the fourth option then you find that every time you times one of the values of the price of lemonade you get the corresponding orange juice price in the sequence and therefore the fourth option, bottom right answer, is the correct choice.
Answer:
The answer is Each glass of lemonade costs 1 1/2 times the cost of orange juice
