Answer:

0.07

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the square is equal to divide the area of the square by the area of rectangle

Let

x-----> the area of square

y----> the area of rectangle

P -----> the probability

P=\frac{x}{y}

<em>Find the area of square (x)</em>

A=5^{2}=25\ in^{2}

<em>Find the area of rectangle (y)</em>

A=25*15=375\ in^{2}

Find the probability P

P=\frac{25}{375}=0.07

Danielle is x years old. Her sister is five years older and her brother is half Danielle’s age. Write an expression in simplest
Alborosie
Let x = Danielle, x + 5 = her sister, and .5x = her brother.

x + x + 5 + .5x = the sum of their ages.

Then we simplify to get 2.5x + 5 = the sum of their ages.

Answer:

The simplest radical form is 9\sqrt{5} ⇒ (c)

Step-by-step explanation:

To simplify any square root;

  • Factorize the number under the root using prime numbers
  • Take out the root any number repeated twice as one number

<em><u /></em>

<em><u>Examples:</u></em>

1. Simplify \sqrt{8}

factorize 8 using prime numbers

8 = 2 × 2 × 2, then \sqrt{8}=\sqrt{(2)(2)(2)}

Take two of 2 out the root, then \sqrt{8}=2\sqrt{2}

2. Simplify \sqrt{18}

factorize 18 using prime numbers

18 = 2 × 3 × 3, then \sqrt{18}=\sqrt{(2)(3)(3)}

Take the two 3 out the root, then \sqrt{18}=3\sqrt{2}

Let us simplify 3\sqrt{45}

∵ 45 = 3 × 3 × 5

∴ 3\sqrt{45}=3\sqrt{(3)(3)(5)}

→ Take the two 3 out by one 3

∴  3\sqrt{45}=3(3)\sqrt{5}

→ Multiply the numbers out the root

∴ 3\sqrt{45}=9\sqrt{5}

∴ The simplest radical form is 9\sqrt{5}

The product of a number and four, increased by one, is at least 7.
faust18 [17]

Answer:

4/6

Step-by-step explanation:

a number which means "x" or u can name any variable u want

so the product of a number and four means

X×4

the increased by one or plus one

X×4+1

is at least 7

X(4)+1=7

4x+1=7

4x=7-1

4x=6

x=4/6

i guess so

lemme know if I'm right
