Dimitri is putting away his toy cars in a container. Each of his cars weighs 1.25 ounces. Dimitri has 50 toy cars. If the container can hold up to 60 ounces without breaking, will the container hold all the cars without breaking?

Yes; they weigh 50.5 ounces.

No; they weigh 61.25 ounces.

Yes; they weigh 51.25 ounces.

No; they weigh 62.5 ounces.



ANSWER ASAP PLSS!!!!!

Answers

Answer:

No

Step-by-step explanation:

If you multiply 1.25(50) is 62.5

and 62.5 is larger than 60

so,

:• No; they weigh 62.5 ounces

Answer: D

Step-by-step explanation:

Facts

each car ways 1.25 ounces

he has 50 cars

his container can hold 60 ounces

The question: Will the container hold all the cars without going over 60 ounces?

Step 1: Find the total number of ounces for all 50 cars

1.25 x 50= 62.5

Step 2: Compare

62.5 > 60

Because 62.5 is greater than 60, all of the cars CANNOT fit.

PLEASE HELPP ASAP Gavin has two bags of titles. The number and colors of the titles are shown in the table. If Gavin randomly draws one tile from each bag what is the probability that he will select two black tiles?

Answers

Answer:

the answer is 7/27 cause you find the total number of tiles and total number of black tile then put it in the ratio of :

total no of black tiles/ total tiles

Answer:

The answer is 7/27

Step-by-step explanation:

For this you will be using What you want over the total of what you have. Sum all the things which gives you: 27 in total.

You want only the black ones, so add 3+4 and you get 7

What you want is the black (7) over the total amount you have (27)

If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?

Answers

Answer:

20%

Step-by-step explanation:

Method 1

Percentage of people who preferred red:

= 13%

Percentage of people who named a rainbow color:

= 13 % + 4% + 5% + 15% + 16% + 12%

= 65%

Percentage of people who preferred red from those who named a rainbow color:

= (13% ÷ 65%) × 100

= 20%

Method 2

Number of people who preferred red:

= 13% of 500

= 13% × 500

= 0.13 × 500

= 65

                                                       

Percentage of people who named a rainbow color:

= 13 % + 4% + 5% + 15% + 16% + 12%

= 65%

Number of people who named a rainbow color:

= 65% of 500

= 65% × 500

= 0.65 × 500

= 325

Percentage of people who preferred red from those who named a rainbow color:

= (number who preferred red ÷ number named rainbow color) × 100

= (65 ÷ 325) × 100

= 20%

Pls Brainliest!

Answer:

20%

Step-by-step explanation:

The rainbow colors add up to 13 + 4 + 5 + 15 + 16 + 12 = 65 percent of the pie chart. So, 65% ∙ 500 = 325 people in the survey named a rainbow color. Of these, 13% ∙ 500 = 65 named red.

Therefore, if we consider only the 325 people who named a rainbow color, the percentage of those people who preferred red is

65/325 = 1/5 = 20%

(You may notice that the answer would still be 20% even if the total number of people in the survey were some number other than 500. This is because 13% is 20% of 65%, no matter what these are percentages of!)

Leena pulls a blue tile out of a bag of same-size tiles without looking. There are 4 purple tiles, 6 blue tiles, and 8 green tiles left in the bag. Find the theoretical probability that the next tile she picks is the same color and the probability that it is a different color. Is it likely the next tile she picks will match?

Answers

Answer:

1/3

Step-by-step explanation:

To find the probability of finding a blue tile you have to find blue tiles over the total number of tiles

First, we have to find the total amount of blue tiles

4 purple 6 blue 8 green

we have 6 blue tiles

Next, we have to find the the total amount of tiles

4+6+8=18

( brainliest ) Susan is buying 5 and a half pies from the market. Write this amount as a mixed number, improper fraction, decimal and percent.

Answers

The amount of pies in mixed numbers is 5*1/2   and  in the improper fraction is 11/2 and in decimal is 5.5 and in percentage is 5.5%

Given: Susan buys 5 and a half pies from the market.

To find the value of the pies in the following ways:

Mixed fractionImproper fractionDecimalPercent

The mixed fraction is represented as a whole number and also as a fraction. It is the mixture of a whole number and a fraction. The simple way to find out the mixed fraction is, first multiply the value in the denominator by the value of the whole number in the mixed fraction. Later add the obtained number. Here is the problem the mixed fraction can be written as 5*1/2.

The improper fraction is identified when the numerator is greater than the denominator. From the given question the value of pies in the improper fraction is given by 11/2. Here 11 is greater than 2.

Next, the decimal number is represented by a whole number that is separated from the decimal point of the fractional part. In question 5 and a half is represented as 5.5, where 5 is a whole number with a decimal point and the fractional part is 0.5.

The value of the percent is obtained by dividing the total value and multiplying it by 100. So from the question, we get 5*1/2*100 is equal to 250 or 5.5%.

Turtles can live a long time. This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalamazoo Zoo:

A box turtle and a map turtle escape from the reptile house of the Kalamazoo Zoo. The box turtle is older than the map turtle. The average age of the turtles remaining at the zoo after the escape is 1 year less than the average age before the escape.

What is the age of the escaped box turtle?

Answers

Answer:

1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67

The average age  is  22 yrs

The sum  of the ages  is  440 yrs

When  two  of the turtles leave, the average is  21 yrs....and there are 18 turtles left

So....the sum of the ages is  21 * 18  = 378

And the difference  in the sums  is  62

The only two values that sum to 62  are  26 and 36

So.....the box turtle must have been 36 and the map turtle must have been 26

Step-by-step explanation:

The age of the escaped box turtle is 36 years in the reptile house of the Kalamazoo Zoo.

What is the stem-and-leaf diagram?

A stem-and-leaf diagram is a quantitative assessment of a collection of data in which the data values are divided into a "stem" (the first digit of the number) and a "leaf" (the remainder of the number) (the last digit of the number).

This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalamazoo Zoo:

1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67

To find the age of the escaped box turtle, we can first find the average age of all the turtles before the escape. To do this, we can add up all the ages and divide by the number of turtles:

(1+1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63+67)/20 = 26

The average age of the turtles remaining at the zoo after the escape is 1 year less than the average age before the escape, so the average age of the turtles remaining at the zoo is 26 - 1 = 25 years.

To find the age of the escaped box turtle, we need to subtract its age from the average age of the remaining turtles.

Let's represent the age of the box turtle X. We can set up the equation:

(1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63+67 - X)/19 = 25

We can solve this equation by multiplying both sides by 19 and then subtracting 67 from both sides:

1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63 - X = 475

Then we can add X to both sides to get:

1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63 -X + X = 475 + X

This simplifies to:

X = 36

Therefore, the age of the escaped box turtle is 36 years.

You may use your formula sheet and a calculator.

Question 3 options:

351.68 in³


87.92 in³


175.84 in³


95.18 in³

Answers

Answer:

87.92 in^3

Step-by-step explanation:

Formula for finding the volume of a cylinder:

V=Bh

B= area of the base

h= height

Diameter=4 radius=2 The radius is half of the diameter

The base of a cylinder is a circle, so you would find the area of the circle and multiply it by the height of the cylinder.

V= (3.14*2^2)7

V= (3.14*4)7

V= 12.56(7)

V= 87.92 in^3

Answer:

The answer to this question should be b. 87.92 in^3 because the formula to find the volume of a cylinder is V=TTr^2h. and remember that the radius is half of the diameter so back to the question.

We multiplied 3.14 times 4 because remember that the radius is half of the diameter and we get 2 but remember the exponent so we need to multiplied to the second power 2 times 2 and we get 4 so when we multiplied 3.14 times 4 we get 12.56 and when we multiplied 12.56 times the height which is 7 we get 87.92 so check the choices and see if there is an answer and yes there is so b which is 87.92in^3 is hopefully the correct answer.
