Alberto’s monthly income is $3,200. Part of Alberto’s monthly budget is shown in the table.

Sladkaya [172]

Using the percentage concept, it is found that 40% of Alberto’s income is used to pay for his rent and groceries.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

In this problem:

Alberto’s monthly income is $3,200, hence b = 3200.

He spends 896 + 384 = $1280 in rent and groceries, hence a = 1280.

Then, the percentage is given by:

$P = \frac{1280}{3200} \times 100\% = 40\%$

Drag each title to the correct box. Not all tiles will be used

mestny [16]

Answer:

4, 1, 6.

See explanation

Step-by-step explanation:

You are given the equation

$d=vt-\dfrac{1}{2}at^2$

First subtract $vt$ from both sides:

$d-vt--\dfrac{1}{2}at^2$

and multiply the equation by -1:

$vt-d=\dfrac{1}{2}at^2\ \ \ \ (1)$

Now multiply (1) by 2:

$2(vt-d)=at^2\ \ \ \ \ (2)$

At last, divide by $a$

$t^2=\dfrac{2(vt-d)}{a}\ \ \ \ \ (3)$

Someone help pleaseeee

qaws [65]

Answer:

Part A = D

Part B = 5 and 50

Step-by-step explanation:

Part A:

area = 5*4x = 20x

so, $100 \leq 20x \leq 1000$

Part B:

to leave it only by x, you divide both sides by 20

100/20 = 5, 1000/20 = 50

which $5\leq x\leq 50$
