Choose a number from 101 to 110 write it draw a picture to show it as 10 tens and more.
Answers
Choose a number from 101 to 110, we selected 106. To represent it with tens and ones, draw ten groups of ten for 'ten tens' which equals 100, and then draw 6 individual objects depicting 'and more' to visually show that 106 is 100 plus 6.
To choose a number from 101 to 110 and represent it as ten tens and more, let's select the number 106. The number 106 can be broken down into ten tens (which is 100) and an additional 6 to make up the full number.
A visual representation of this could be:
For the ten tens, you can draw ten groups of ten sticks or circles together, which would represent 100.
For the additional 6, draw six more sticks or circles away from the groups of tens.
So the drawing will show ten sets of ten objects, such as sticks or dots for the tens, and then six individual objects for the ones, clearly indicating that 106 consists of 100 (ten tens) plus 6 more.

the jacksons went camping in a state park.One of the tents they took is shown . What is the volume of the tent.
Answers
The volume of the Jacksons' camping tent is 94.5 cubic feet. To calculate the volume, you multiply the dimensions: height (3.5 ft) by length (6 ft) by width (4.5 ft).
Explanation:The formula for calculating the volume of a rectangular prism is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
The length (l) of the tent is 6 feet, the width (w) is 4.5 feet, and the height (h) is 3.5 feet.Substitute these values into the formula: V = 6 ft * 4.5 ft * 3.5 ft.Multiply the values together: V = 94.5 cubic feet.The volume of the tent is determined by multiplying its length, width, and height. In this instance, the Jacksons' tent has a volume of 94.5 cubic feet, providing ample space for their camping needs. Understanding the volume of a three-dimensional object is essential for assessing its capacity and ensuring it meets the requirements of its intended use.

Without calculating, explain how many decimal places are in the product 0.6 X0.4 X 1.9. Rewrite the expression as the product of two decimals to support your answer.
Answers
Looking at the problem, you see both .6 and .4 are placed to the right of the decimal, otherwise known as the tenths place (1/10).
Looking at 1.9, you see you have one number (1) placed to the left of the decimal, the ones place, and another number placed to the right of the decimal (9), in the tenths place.
Well, this is simple. You can look and see that your multiplying fractions against a whole number, which will of course make this whole number even smaller. By how much though??
Well, you can really tell this by looking at how MANY numbers are behind the decimal. You have .9, .4, and .6
That's 3 numbers behind the decimal place. This may not help you solve the problem itself, but this tells you here (ignoring the 1, that will be taken out immediately while solving and turned into a 0) that you will have 3 numbers placed from the tenths place all the way to the thousandths place.
Basically, this tells you that you'll have three decimal places to the right of the decimal.
As for rewriting your problem to better show this, that's simple too.
All you have to do is simple multiplication, just in the tenths place. How? You know that 6*4 (referring to .6 and .4) is 24, that means that .6*.4 will be .24
How does this support your answer before? .24 has TWO numbers to the right of the decimal. That's TWO decimal places. With the .9 in 1.9, that's still THREE decimal places to the right of the decimal, and your answer would be the same.
So, here's it re-written.

The product 0.6 x 0.4 x 1.9 has three decimal places.
Explanation:To determine the number of decimal places in the product 0.6 x 0.4 x 1.9, we can rewrite each decimal as the product of two decimals and count the total number of decimal places.
0.6 can be written as 0.6 x 1.0, which has one decimal place.
0.4 can be written as 0.4 x 1.0, which also has one decimal place.
1.9 can be written as 1.9 x 1.0, which has one decimal place.
Since each decimal has one decimal place, the product 0.6 x 0.4 x 1.9 has a total of three decimal places.

Carter has 60 balloons. 4/12 of the balloons are black, and 3/12 of the balloons are white. The rest of the balloons are red. Which series of calculations shows how many red balloons Carter has?
Answers
B------------> black balloons
W-----------> white balloons
R-----------> red balloons
Step 1
calculate the amount of black balloons and white balloons
the total of balloons is 60
B=(4/12)*60=20 balloons
W=(3/12)*60=15 balloons
Step 2
calculate the amount of red balloons
R=60-[B+W]---------> R=60-[20+15]
R=60-(35)=25 balloons
the answer is 25 red balloons
To find the number of red balloons Carter has, subtract the number of black and white balloons from the total number, using fractions to represent the proportion of black and white balloons. Multiply the total number of balloons by the fraction representing red balloons to find the number of red balloons.
Explanation:To find the number of red balloons Carter has, we need to subtract the number of black and white balloons from the total number of balloons. Since 4/12 are black and 3/12 are white, we can add these fractions together to find the total fraction of balloons that are either black or white: 4/12 + 3/12 = 7/12.
To find the fraction of balloons that are red, we can subtract the fraction of black and white balloons from 1 (since the sum of all fractions should equal 1): 1 - 7/12 = 5/12.
To find the actual number of red balloons, we can multiply the total number of balloons (60) by the fraction of red balloons: 60 x 5/12 = 25 red balloons.

If a population of 100 cells triples every hour, which function represents p(t), the population after t hours?
Answers
The function that describes a cell population of 100 cells tripling every hour is stated by the formula p(t) = 100(3)^t, which represents exponential growth.
Explanation:This problem describes a phenomenon where the initial population experiences exponential growth in a way that it triples every hour. Exponential growth is typically represented by the function p(t) = p⁰×r^t, where:
- p(t) represents the final amount of entities (in this case, population) after time t,
- p0 is the initial amount of entities (in this case, initial population),
- r is the growth factor,
- and t is time.
In these types of problems, the base number of the exponent (in this case 3) represents the growth factor. This is based on the fact that every time period (in this case, every hour), the population triples, or in other words, gets multiplied by 3.
The initial population given is 100 cells. This is represented by p0 in our formula and is also the coefficient in our function.
By considering both the initial population and the rate at which it triples, we can construct the function as p(t) = 100 × 3^t.
Therefore, according to our built function, the correct choice is b. p(t) = 100 × 3^t.

60 is 20% of 300.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Let x% be a number such that
x% of 300 is 60
This forms an equation in one variable which can be solved by transposition.
[tex]x/100\times 300=60[/tex]
Simplifying it to calculate value of x.
On multiplying 100 both sides,
[tex]300x=6000[/tex]
On dividing 300 both sides,
x=20%
Thus, 20% of 300 is 60.

Answers
Final answer:
Dennis's other number, considering the conditions of only having 1 and 3 as common factors and 18 as the least common multiple with 9, is 6.
Explanation:
To solve the problem regarding Dennis's numbers, it's crucial to understand the conditions provided: the numbers only share common factors of 1 and 3, one of the numbers is 9, and their first common multiple is 18. To find the other number, knowing one of the numbers allows us to apply the rule of least common multiples (LCM). Since 9's factors are 1, 3, and 9, and the LCM with the other number is 18, this other number must be divisible by itself and 3 but not be a multiple of 9 to maintain the unique common factors condition. The only number that satisfies the condition in which 18 is the LCM and shares only 1 and 3 as common factors with 9, would be 6, since 18 is the smallest number that both 9 and 6 can divide into without other common multiples.
