Step-by-step explanation:

1.

The Trapezoid Midsegment Theorem states that a line segment connecting the midpoints of the legs of the trapezoid is parallel to the bases, and equal to half their sum.

In this problem you can see that 5x - 1 is the midsegment of the trapezoid, so using the rule:

[tex](21 + 27) / 2 = 5x -1[/tex]

solve:

[tex]48/2 = 5x-1\\24 = 5x - 1\\25 = 5x\\x= 5[/tex]

Answer:

351π cm^2.

Step-by-step explanation:

Area of shaded part = area of the large circle - area os small circle

= π * (13+7)^2 - π * 7^2

= 400π - 49π

= 351π.

Answer:

d = 9.84 m

Step-by-step explanation:

The dimensions of an envelope are 9 inches by 4 inches.

We need to find the maximum possible length of the pencil.

Let it be d. It can be calculated using Pythagoras theorem such that,

[tex]d=\sqrt{9^2+4^2} \\\\d=9.84\ m[/tex]

So, the maximum possible length of the pencil is 9.84 m./

Answer:

[tex]\sqrt{29} ,6,2\pi ,3\sqrt{8}[/tex]

Step-by-step explanation:

Hello there!

First lets find the value of each irrational number

[tex]6 = 6\\\\\sqrt{29} =5.385164807\\\\2\pi =6.283185307\\\\3\sqrt{8} =8.485281374[/tex]

now we can easily put them in order from least to greatest

5.3,  6,   6.2,  8.4

then we change it to its irrational form

so the correct order would be

[tex]\sqrt{29} ,6,2\pi ,3\sqrt{8}[/tex]

So Sophia ate 5% of the pizza

Answer:

Sophia ate 5%.

Step-by-step explanation:

Caden ate 20%. Zoe ate 50% more than him, so 150% of 20%. That is 20+half of 20, which is 30. So zoe ate 30%. Noah ate 50% more than her, so 150% of 30%, which is 45%. Add them together and get 95%. That leaves 5% for Sophia to eat.

Answer:

9x/y³

Step-by-step explanation:

The simplification of the expression 9x⁰y⁻³ will be 9/y³.

Index (indices) in Maths is the power or exponent which is raised to a number or a variable.

In another word the mathematics of power or exponent of any number is called indices.

As per the given expression,

9x⁰y⁻³

By the law of indices that, [tex]x^{-m}[/tex] = 1/[tex]x^{m}[/tex]

9x⁰y⁻³ = 9x⁰ × 1/y³

⇒ 9(1)/y³ = 9/y³

Hence "The simplification of the expression 9x⁰y⁻³ will be 9/y³".
