A) 6a=5b so a=5/6*b a/b=5/6
b) 6a=5b so 6/5*a=b b/a=6/5
c) a/b=5/6 so (a/b)*(2/7)=2a/7b=(2/7)(5/6)=(5/21)
d) 6a=5b so b=6a/5 Thus (a+b)/b=(a+6a/5)/(6a/5)=(11a/5)/(6a/5)=11/6
e) 6a=5b so a=5b/6 Thus (a+b)/(5a)=(5b/6+b)/(5*5b/6)=(11b/6)/(25b/6)=11/25
f) (3a+3b)/(a+b)=3=3/1

I know E and F

e) 6a=5b so a=5b/6 Thus (a+b)/(5a)=(5b/6+b)/(5*5b/6)=(11b/6)/(25/6)=11/25
f) (3a+3b)/(a+b)=3=3/1

Alonso went to the market with $55 to buy eggs and sugar. He knows he needs a package of 12 eggs that costs $2.75. After getting

vodka [1.7K]

Answer:

1) The inequality is $55 ≥ $11.50 × S + $2.75

2) Alonso can afford 4 boxes of sugar

Step-by-step explanation:

The given information are;

The total amount with Alonso = $55

The amount of eggs Alonso needs = 12 eggs

The costs of the pack of 12 eggs = $2.75

The number of packs of eggs Alonso buys = 1

The cost of each box of sugar = $11.50

Let the number of boxes of sugar Alonso buys = S

Given that the total amount of money with Alonso is $55, then the inequality will be such that $55 will be equal to or larger than the expression for items bought

Therefore, the inequality is given as follows;

$55 ≥ $11.50 × S + $2.75

2) To find out how many boxes of sugar Alonso can afford, we have;

$55 ≥ $11.50 × S + $2.75

$55 - $2.75≥ $11.50 × S

$52.25 ≥ $11.50 × S

∴ S ≤ $52.25/$11.50 = 4.54

S ≤ 4.54 boxes of sugar

As the sugar comes in whole boxes, Alonso can therefore afford only 4 whole boxes of sugar.

Alonso can afford to buy 4 boxes of sugar.

Solve the inequality.

Mars2501 [29]

To solve an inequality, get the variable you're solving for on one side of the inequality and everything else on the opposite side.

$\frac{2}{5} \geq x - \frac{4}{5}$

You get the x variable on it's own by undoing the operations done to it.

For example, if x is being multiplied by 5, you undo the multiplication operation by using the inverse of multiplication. Which is division.

We need to add $\frac{4}{5}$ to both sides of the inequality to undo the subtraction operation done to x.

$\frac{2}{5} + \frac{4}{5} \geq x - \frac{4}{5} + \frac{4}{5} \\ \\ \frac{6}{5} \geq x$

Convert the improper fraction into a mixed number.

$\frac{6}{5} = 1 \frac{1}{5}$

So, D 1 1/5 ≥ x is the answer.

A hemisphere has a diameter of 48 inches. What is the volume of the

ss7ja [257]

Answer:

9,216π or 28,938.2 meters³

Step-by-step explanation:

Given: diameter 48 inches

Radius 24 inches

Note:

Volume of hemisphere = volume of sphere / 2

Volume of hemisphere = 1/2 • 4/3 • πr³

= 1/2• 4/3×π×24³

= 1/2•18432π

= 9,216π

= 28,938.2 meters³
