The question seems to be asking whether the number 846 can be classified in terms of its placement in the tens place value or not. To understand this, let's break down the number 846 in terms of place value. The number 846 is comprised of three digits, each representing a different place value in the base-10 numbering system. Starting from the right, the first digit (6) represents the ones place, the second digit (4) represents the tens place, and the third digit (8) represents the hundreds place.

Therefore, yes, 846 does have a component in the tens place, which is the digit 4. This means that the number 846 has 4 tens or 40 when breaking it down by place value. Understanding place value is crucial in mathematics as it helps in doing calculations, understanding the value of numbers, and in various operations such as addition, subtraction, multiplication, and division. The tens place specifically is important when dealing with numbers ranging from 10 to 99 and beyond, as it helps in grouping numbers in units of ten, simplifying calculations, and enhancing comprehension of numbers' sizes.

Answer:

kiki has $4.17 and jordan has $4.14 kiki has 0.03 more than jordan

Step-by-step explanation:

If you add up the numbers for kiki you get $4.17 and if you do the same for jordan with the numbers they gave you for him you get $4.14 then you just minus 4.17 and 4.14 and thats how you get 0.03.

Answer:

Kiki has $0.03 more than Jordan, meaning Kiki has more money.

Step-by-step explanation: It's simple! Add 2.48 + 1.69 = 4.17 (This is Kiki's total amount) And then add 3.05 + 1.09 = 4.14 (This is Jordan's total amount)

As we can see, Kiki has more money. To find the difference we simply do 4.17 - 4.14 = 0.03 (:

Answer:

h = 2

Step-by-step explanation:

(8+h)/10 = 1

8+h = 1×10

8+h = 10

h = 10-8

h = 2

The value of h that makes the equation [tex]\(\frac{8+h}{10} = 1\)[/tex] true is (h = 2).h=2 is the value that, when substituted into the equation, ensures that the left side of the equation (8+h) is equal to the right side (10 times 1).

To find the value of h that satisfies the

equation: [tex]\(\frac{8+h}{10} = 1\)[/tex],

we can start by understanding the equation. It represents a fraction where the numerator is the sum of 8 and h, and the denominator is 10. The fraction is set equal to 1, which means both sides of the equation should be equal.

To solve for h, we can cross-multiply, which simplifies to

(8 + h = 10)

Now, to isolate h, we need to get it on one side of the equation. Subtracting 8 from both sides yields (h = 2).

So, when h = 2, the equation becomes

[tex]\(\frac{8+2}{10} = 1\)[/tex] , which simplifies to [tex]\(\frac{10}{10} = 1\)[/tex],

making it a true statement.

In essence, h=2 is the value that, when substituted into the equation, ensures that the left side of the equation (8+h) is equal to the right side (10 times 1). This demonstrates the solution's validity and satisfies the equation's condition.

Answer:

The first statement.

Step-by-step explanation:

Because when you look at the July graph you can see that the highest number of miles is 15 and the lowest number of miles is 1 so the range is 15 - 1 = 14.

When you look at the August graph you can see that the highest number of miles is 13 and the lowest number of miles is 5 so the range is 13 - 5 = 8

So the range of the July month is greater than the range of the August month

Answer: 11625.8

Step-by-step explanation:

The total amount in the account after 17 years, with an annual interest rate of 7.5%, is approximately $7420.50.

To calculate the amount in the account after 17 years, we use the formula for simple interest: Total future amount (with simple interest) = Principal + (Principal × Interest Rate × Time). In this case, the principal is $3400, the interest rate is 7.5%, and the time is 17 years. Plugging in these values, we get:

Total future amount = 3400 + (3400 × 0.075 × 17)

Calculating this, the total future amount in the account will be approximately $7420.50.

Answer:

Step-by-step explanation:

Let x represent the amount on deposit at 12%. Then 5900-x is the amount deposited at 6%, and the total interest earned is ...

  12%·x +6%·(5900 -x) = 540

  0.06x + 354 = 540 . . . . . . . . eliminate parentheses

  0.06x = 186 . . . . . . . . . . . . . . subtract 354

  x = 3100 . . . . . . . . . . . . . . . . . divide by 0.06

Scott invested $3100 at 12% and $2800 at 6%.

_____

Quick sanity check

The average interest earned is $540/$5900 ≈ 0.0915 ≈ 9.15%. This is more than the average of 12% and 6%, which is (12+6)/2 = 9 percent. Hence more than half of the money must be deposited at 12%.

Step-by-step explanation:

Answer: 4 feet.

Step-by-step explanation:

Their is one rectangular prison divided into two.

The volume of the first one is

V1= L X H X W=80.

Volume of the second one is

V2= L X H X W

V2= 6 X H X 5

V2 = 30H

Now from the question, the total volume is 200cubic feet which means V1 + V2 = 200, recall that V1=80 and V2=30H, so we say;

80+30H=200, collecting the like term we have, 30H=200-80.

30H=120, divide both side by 30

30H/30=120/30

H= 4feet.

Height is 4feet.

Final answer:

To find the height of Rectangular Prism B, subtract Rectangular Prism A's volume from the total volume to get Prism B's volume (120 cubic feet), then divide by the product of its length and width. The height is 4 feet.

Explanation:

The question is about finding the height of Rectangular Prism B given that the solid figure it's part of (when combined with Rectangular Prism A) has a total volume of 200 cubic feet, and that Rectangular Prism A has a volume of 80 cubic feet. Considering volume calculations for rectangular prisms are done using length × width × height, we can find the height of Prism B by isolating height in the formula. Since Prism B has a length of 6 feet and a width of 5 feet, and we know the combined volume of both prisms, we first subtract the volume of Prism A from the total volume to find the volume of Prism B, which is 120 cubic feet (200 cubic feet - 80 cubic feet).

Volume of Prism B = 120 cubic feet. The formula for volume is then applied as follows:

Volume = Length × Width × Height

120 cubic feet = 6 feet × 5 feet × Height

Height = 120 cubic feet / (6 feet × 5 feet)

Height = 120 cubic feet / 30 square feet

Height = 4 feet.

Therefore, the height of Rectangular Prism B is 4 feet.

Answer:

$27

Step-by-step explanation:

f(x) = 5x + 12

= 5(3) + 12

= 15 + 12

= 27

Alex will earn $27 for 3 hours of lawn-cutting work, as calculated using the function f(x) = 5x + 12.

The function f(x) = 5x + 12 models the amount of money, in dollars, Alex makes when cutting lawns for x hours. To calculate the amount Alex will make for 3 hours of lawn-cutting work, we simply substitute x with 3 in the equation:

f(3) = 5(3) + 12

For instance, events G and H (taking a math class and taking a science class, respectively) from Example 3.9 were shown to be independent by verifying that P(G AND H) = P(G) * P(H). Similarly, events A and B from 'Try It Σ' 3.8, learning Spanish and German, were tested for independence by checking if P(A AND B) = P(A) * P(B).

Thus, f(3) = 15 + 12 which equals $27. Therefore, for 3 hours of work, Alex will earn $27.

Final answer:

The probability of being marked tardy when events are mutually exclusive is 0.8, and when they are independent, the probability is 0.09.

Explanation:

The probability that a student will be marked tardy if the events on-time and marked tardy are mutually exclusive is 0.9 - 0.1 = 0.8. When events A and B are independent, the probability of both events occurring is the product of their individual probabilities: P(A and B) = P(A) * P(B). In this case, P(on-time) * P(tardy) = 0.1 * 0.9 = 0.09.

=====================================

Work Shown:

AB + BC = AC .... see diagram below

(3x)+(2x-2) = 18 ... plug in given expressions

5x-2 = 18

5x-2+2 = 18+2 ... add 2 to both sides

5x = 20

5x/5 = 20/5 ... divide both sides by 5

x = 4

Given points A, B and C are collinear, with B between A and C, and the distances between them expressed in terms of 'x'. We use the fact that AB + BC = AC to form an equation, solve it to find 'x' = 4.

To solve for 'x' in this problem, we need to utilize the fact that points A, B, and C are collinear and that point B is between A and C.

Given AB = 3x, BC = 2x - 2, and AC = 18.

When points are collinear and one is between the other two, the sum of the distances between the points equals the total distance. So, we know that AB + BC = AC.

Substitute the known values into this equation to get 3x + 2x - 2 = 18.

Combine like terms to give 5x -2 = 18. Rearrange this to make 'x' the subject, you get 5x = 20, then x = 4.

So the value of 'x' that satisfies the given conditions is 4.
