Ram ordered 10 pizzas which were cut into a total of 66 slices. Mediums pizzas are cut into 6 slices. Mediums pizzas are cut into 6 slices, while large pizzas are cut into 8 slices. How many medium pizzas did he order?

Answers

Answer:

4 medium and 6 large.

Step-by-step explanation:

A possible answer to this is

10 pizzas, 66 slices.

the sum of slices needs to be 66 and canot exceed 10 pizzas in total.

6x4=24 slices

8x6=42 slices

4+6= 10 so it does not exceed 10 pizzas.

24 +42= 66 so there are 66 slices.

Mr. Birdie has worked hard as a Math teacher all his
life and has saved 42 a million dollars. A savings bank
has offered him 4% interest per annum on his savings.
Mr Birdie is retiring at 65 and wants enough to live on
until his 90th birthday. He figures that he will have
$1666.66 a month.
Can you explain where his calculation may have come
from if it is correct. Explain your thoughts in the box
below.

Answers

Answer:

You'll likely need assets worth 10 to 16 times your salary by the time you leave your job. A 45-year-old making $120,000 who hopes to retire at age 60, say, should already have nearly $700,000 set aside. (See the Retire Early calculator.) You can get by with less if you'll have other sources of income.

Dear journal, I'm not an outdoorsy kind of girl, but when my neighbor Adelle invited me to go camping, I could hardly tell her I was afraid of bears and snakes and pretty much any wild animal. I had images of waking up in the middle of the night, my tent shaking to the rhythm of growls. I couldn't let Adelle know I was afraid. So, I packed my bags and waited at the door the morning we were to leave. To my great surprise, I discovered that camping isn't at all how I imagined. The park ranger assured us that no bears had been seen in the last five years, and to my great surprise, Adelle's family had a pop-up camper, so we weren't even in a tent. Adelle did get to see my true colors, though, when we were hiking. We came across a snake in the middle of the trail, and I've never run so fast in my life. Snakes aside, camping's not so bad. What techniques could be used to improve this sample diary entry to make it interesting and effective at sharing the experience? Check all that apply. adding reasons why the speaker was afraid adding some dialogue adding more description about what was enjoyable about the camping trip adding more information about bears adding a description of the pop-up camper

1) If there are 54 people in a class and the ratio of girls to total people is 2:5, how many
girls and boys are there in the class?

Answers

From the ratio you can deduce 2:5 girls and 3:5 boys. Divide 54 by 5 and you get 10.8. 10.8*2 = 21.6 and 10.8*2= 32.4 which adds to the total 54. There cannot be a fraction of a person, you need to round the decimals. There are 22 girls and 32 boys.

There are 22 girls and 32 boys in the class.

Ratio and proportion :

Given that,  there are 54 people in a class

and the ratio of girls to total people is [tex]2:5[/tex]

Number of girls in the class is,

What is an equation of the line that passes through the points (3, -3) and (6,-1)?

Answers

Answer: 2/3x - 5

Step-by-step explanation:

The equation of a line passing through the given points is y = 2x/3-3

What is an equation?

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, a line is passing through the points (3, -3) and (6,-1)

We know that, the equation of a line passing through two points is given by,

y-y₁ = (y₂-y₁/x₂-x₁)(x-x₁)

Therefore,

y+1 = (-1+3)/(6-3)(x-3)

y+1 = 2/3(x-3)

y = 2x/3-2-1

y = 2x/3-3

Hence, The equation of a line passing through the given points is y = 2x/3-3

A PAIR OF JEANS MARKED AT R450 IS SOLD AT DISCOUNT OF 25%.​

Answers

Original price is the jeans = Rs450

Discount = 25%

Discount amount

= 25% of 450

= 25%(450)

= 25/100 × 450

= 25/10 × 45

= 5/2 × 45

= 225/2

= Rs112.5

Price after discount

= original price - discount amount

= 450 - 112.5

= Rs337.5
