If 48 eggs are used in the cafeteria today but the number expected to be
used tomorrow is 50% less than that, how many eggs are expected to be
used tomorrow?*
Answers
Answer:34
Step-by-step explanation:
Eggs expected to be use tomorrow is 48 - 30% of 48
30% of 48 = 30/100 × 48
= 0.3 × 48 =14.4
48 - 14.4 = 33.6
= 34 to the nearest whole number
Answer:
24 eggs
Step-by-step explanation:
So since it is 50% less. That must mean it is half of that sense 50% is half. So 48x0.5=24

An isosceles right triangle has a hypotenuse length that can be modeled with the function h(x) = sqaure root of 2 The combined
length of the legs can be modeled with the function L(x) = 2x.
Which function, p(x), can be used to find the perimeter of the triangle?
A. P(x)=x/2 √2 + x
B. P(x)=x √2 +2x
C. P(x) = x √2 + 4x
D. P(x) = 2x √2 + 4x
Hurry timed!!
Answers
The legs are defined by [tex]L(x) = 2x[/tex]. The Hypotenuse if defined by [tex]h(x) = L(x)\cdot \sqrt{2}[/tex]. The perimeter is defined by:
[tex]p(x) = h(x)+2\cdot L(x) \\~\\p(x) = L(x)\cdot\sqrt{2} +2\cdot L(x) \\~\\p(x) = L(x)\cdot\left(\sqrt{2}+2\right) \\~\\p(x) = 2x\cdot\left(\sqrt{2}+2\right) \\~\\p(x)= 2\sqrt{2}x+4x[/tex]
D. P(x) = 2x √2 + 4x
The perimeter of the isosceles right triangle will be P(x) = x√2 + 2x. Then the correct option is B.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The sum of all the sides of the triangle will be known as the perimeter of the triangle.
In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.
An isosceles right triangle has a hypotenuse length that can be modeled with the function h(x) = x√2.
The combined length of the legs can be modeled with the function L(x) = 2x.
Then the perimeter of the isosceles right triangle will be
P(x) = h(x) + L(x)
P(x) = x√2 + 2x
Thus, the perimeter of the isosceles right triangle will be P(x) = x√2 + 2x.
Then the correct option is B.

Answers
Answer:
4x^2/3Step-by-step explanation:
Given the expression (8x)^2/3
This can also be expressed as;
(8x)^2/3

= 2^2 * x^2/3
= 4x^2/3
