polet [3.4K]

Answer:

The number of pizzas sold during A- lunch is 64

Step-by-step explanation:

Let us solve the question using the ratio method

∵ The ratio of pizza to nachos sold during A-lunch is 4 to 3

∵ There were 48 nachos sold

→ By using the ratio method

→ Pizza  :  Nachos

→  4        :   3

→  x        :  48

→ use the cross multiplication

∵ x × 3 = 4 × 48

∴ 3x = 192

→ Divide both sides by 3

∵ \frac{3x}{3} = \frac{192}{3}

∴ x = 64

∴ The number of pizzas sold during A- lunch is 64

The amount of chlorophyll in a leaf changes based on outside temperature. What's the independent variable in the situation?
I am Lyosha [343]

Answer:


Step-by-step explanation:

Given that the amount of chlorophyll in a leaf changes based on outside temperature. Here there are two variables.

i) Amount of chlorophyll in a leaf

ii) outside temperature

Here outside temperature is an independent variable as amount of chlorophyll in a leaf cannot control it.

But on the other hand, Amount of chlorophyll in a leaf depends on the outside temperature and hence cannot be independent but dependent variable

Recall the definition of dependent and independent variable

An independent variable is the variable that is controlled in a scientific experiment to test the effects on the dependent variable.

A dependent variable is the variable being tested and measured in a scientific experiment.

A company sells its printers to customers in order to make a profit of 25% calculate the price the company paid for a printer wh
ioda

The company paid $2000 for the printer

Step-by-step explanation:

Let x be the price of the printer for which the company bought it.

If x is the price of printer, then 25% of x will be the profit made by the company.

That is:

0.25x

According to the statement,

The cost and profit earned by company are equal to 2500

So,

x+0.25x = 2500\\1.25x = 2500

Dividing both sides by 1.25

\frac{1.25x}{1.25} = \frac{2500}{1.25}\\x = 2000

Hence,

The company paid $2000 for the printer
