Answer:
B
Step-by-step explanation:
Roots can also be represented as indicies (exponents) and thus should be treated like them. For example, square root could also be written as exponent 1/2.
When dealing with square roots in a equation, PEMDAS calls for this to be solved when you do B. Exponents
The root of a number is that number expressed exponentially by the root in inverted form. In other words, when you take something to its square root, you would be taking it to the inverse of 2 which is 1/2.
For instance:
√4 = 2 = 4¹/²
This means that you can then solve the square root when you deal with exponents which is the second step.
In conclusion, if you see an expression with square roots, PEMDAS allows you to solve it as an exponent.

Find the perimeter of the triangle, in cm. What is the most efficient strategy you can find to solve this problem?
solution:
27, 35, and 32 are each the sum of a different pair of sides of the triangle
Then 27 + 35 + 32 is the sum of all three sides, each counted twice.
Thus, 27 + 35 + 32 = 94 is twice the perimeter
therefore,
the perimeter of the triangle is 94/2 = 47 cm.
Step-by-step explanation:
since the sides r of 2 triangles
actually perimeter = ans/ 2
perimeter of a triangle = sum of all sides/2
27+35+32/2 =94/ 2 = 47 ans

true or false. Any 3 distinct points are always coplanar
Answer: False
Step-by-step explanation:
Three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a single plane. Two lines in three-dimensional space are coplanar if there is a plane that includes them both.
Answer:
Coplanar means "lying on the same plane". Points are coplanar, if they are all on the same plane. Any three points are coplanar but with more than three points, there is the possibility that they are not coplanar so its false.

X/2 + 1 =7 .........
Answer:
x = 12
Step-by-step explanation:
x/2 + 1 = 7
Subtract both sides
x/2 + 1 - 1 = 7 - 1
x/2 + 0 = 6
x/2 = 6
Multiply both sides
x/2 * 2 = 6 * 2
x = 12

Use the Pythagorean’s theorem to calculate the length of the hypotenuse of a right triangle with 17 as the length and 15 as the width
Answer:
[tex]\huge\boxed{\text{Around\ \ } 23}[/tex]
Step-by-step explanation:
The Pythagorean Theorem states that
[tex]a^2 + b^2 = c^2[/tex]
Where [tex]a[/tex] is one leg of the triangle, [tex]b[/tex] is the other, and [tex]c[/tex] is the hypotenuse.
Since we know the legs and we need to find the hypotenuse [tex]c[/tex], we can substitute inside the equation with the values 15 and 17.
[tex]15^2 + 17^2 = c^2\\\\225+289 = c^2\\\\514 = c^2\\\\c = \sqrt{514}\\\\c \approx 23[/tex]
Hope this helped!
Answer:
Hypotenuse = 22.67
Step-by-step explanation:
[tex]a^2 + b^2 = c ^2\\[/tex]
a = One Leg
b = Another Leg
c = Hypotenuse
[tex]17^{2} + 15^{2} = c^2[/tex]
289 + 225 = [tex]c^2[/tex]
514 = [tex]c^2[/tex]
[tex]\sqrt{514} = c[/tex]
c = 22.67

¿Cuántas libras de café “La Finca” que se vende a $5 la libra debe mezclarse con 80 libras de
café común que se vende a $2 la libra, para hacer una mezcla que se venda a $3 la libra?
Answer:
Thew answer is "40 pounds".
Step-by-step explanation:
The value of x pound is $5
It's mixed with 80 pound
Formula:
[tex]\text{Average price} = \frac{\text{Rate of both}}{\text{weight of both}}[/tex]
Average price = 3
[tex]\to 3 = \frac{5\times x+ 2\times 80}{x+ 80}[/tex]
[tex]\to 3 = \frac{5x+ 160}{x+80}\\\\\to 3(x+80) = 5x+ 160 \\\\\to 3x+240 = 5x+ 160 \\\\\to 240-160 = 5x-3x \\\\\to 80 = 2x \\\\\to 2x=80 \\\\\to x=\frac{80}{2} \\\\\to x= 40[/tex]

what is 1/120 as a decimal
Answer:0.0083
Step-by-step explanation:
0.0083 is 1/120 as a decimal.
A decimal is a number that contain of a whole and a fractional part. Decimal numbers lie in the middle of integers and represent numerical value for quantities that are whole plus some part of a whole.
We get decimals when we smash a whole into smaller parts.
A decimal number then has two components: a whole number part and a fractional part. The decimal place value system for the whole part of a decimal number is the alike the whole number value system.
However, we obtain the fractional part of the decimal number as we move toward the right after the decimal point.
1/ 120 = 0.0083.
Therefore, 0.0083 is 1/120 as a decimal.

Given two consecutive integers. The sum of four times the first integer and six times the second integer is 96. Find the integers.
Find the First Integer and Second Integer
Hey there! I'm happy to help!
If these are consecutive integers it means that they are one apart. Let's call our numbers x and y and create a system of equations. Our x will be the first integer and y will be the second.
y=x+1
4x+6y=96
We plug our y value into the second equation to solve for x.
4x+6(x+1)=96
We use the distributive property to undo the parentheses.
4x+6x+6=96
We combine like terms.
10x+6=96
We subtract 6 from both sides.
10x=90
And divide both sides by 10.
x=9
Since y is x+1, we know that y is 10.
Our integers are 9 and 10.
