The standard form will be:

a. 3.15

b. 3.015

<h3>How to calculate the value?</h3>

It should be noted that the question is simply about converting the expanded form to standard form.

This will be:

(3 × 1) + (1 × 0.1) + (5 × 0.01)

= 3 + 0.1 + 0.05

= 3.15

b. (3 × 1) + (1 × 0.01) + (5 × 0.001)

= 3 + 0.01 + 0.005

= 3.015

Dvinal [7]

Answer:

2, 3, 7

Step-by-step explanation:

Since you know your multiplication tables, you know that ...

42 = 6 × 7

and

6 = 2 × 3

The numbers 2, 3, and 7 are prime numbers (not further divisible). This list is in order least to greatest, so is the combination of the lock.

What is the domain and range of the square root of x+3-1?

Nata [24]

Answer:

$\large\boxed{\text{The domain:}\ x\geq-3\to x\in[-3,\ \infty)}\\\boxed{\text{The range:}\ y\geq-1\to y\in[-1,\ \infty)}$

Step-by-step explanation:

$y=\sqrt{x+3}-1\\\\The\ domain:\\\\x+3\geq0\qquad\text{subtract 3 from both sides}\\\\x\geq-3\to x\in[-3,\ \infty)\\\\The\ range:\\\\\sqrt{x+3}\geq0\qquad\text{subtract 1 from both sides}\\\\\sqrt{x+3}-1\geq-1\\\\y\geq-1\to y\in[-1,\ \infty)$

GO.o has 3 orange picks for every 2 green. If there are 25 picks in all, how many picks are orange?

Reika [66]

Given

GO.o has 3 orange picks for every 2 green

there are 25 picks in all

Find out how many picks are orange.

To proof

As given in question

GO.o has 3 orange picks for every 2 green

i.e the ratio of orange to every green becomes

$\frac{Orange}{Green}:\frac{3}{2}$

total number of picks = 25

let the GO.o pick of 3 orange picks for every 2 green =x

than the equation becomes

3x + 2x = 25

5x = 25

x = 5

Than

the number of oranges = 3x

putting the value of x

= 15

the number of green = 2x

= 10

thus the 15 picks are orange.

Hence proved

I need to know number six and thank you guys for all the help

Zigmanuir [339]

Answer:

Step-by-step explanation:

First of all, a very easy way is to count all the rectangles and then count the squares that are shaded and have balloons.

You'll get 7 squares that are shaded and have balloons and 16 rectangles in total.

So the fraction will be $\frac{7}{16}$

Another simple way is to just multiply $\frac{7}{8}$ and $\frac{1}{2}$

$\frac{7}{8}*\frac{1}{2}=\frac{7}{16}$
