what is the product of −2 1/4 and −4 1/2 ?

Answers

Answer 1

To multiply fracti0ons, we need to convert them to improper fractions:

-2 1/4 = -9/4
-4 1/2 = -9/2

Now, lets multiply:

-9/4 * -9/2 = 81/8

Hope this helps!

Take note that the answer is positive because when multiplying, two negatives make a positive.

Problem 1) Line n is the line of symmetry (not line o) because we can fold the lower half to match up with the upper half. The folding line is over line n.

Problem 2) I agree. Nice work on getting the correct answer. The folding line is a vertical line through the center

Problem 3) It's hard to say for sure, but I think the top left corner is NOT reflective over any line of symmetry no matter how you rotate it. So I would uncheck that box. I agree with your other choices though. Great job with those.

B.) 0.58, 0.63, 0.06, 0.059
C.) 0.06, 0.58, 0.059, 0.63
D.) 0.059, 0.06, 0.58, 0.63

Answers

greatest to least : 0.63 , 0.58, 0.06, 0.059

u basically start by looking at the first number to the right of the decimal...look at only that one number....now which one is biggest...it is the 6 in 0.63....now continue doing that and u will see that the 5 in 0.58 comes next...but then ur left with 2 numbers that have a 0 in that spot...so move over another number (to the right)...and compare those numbers....so the next one is the 6 in 0.06...and lastly, the 0.059.

Final answer:

The largest to smallest order of the numbers 0.63, 0.58, 0.059, and 0.06 is 0.63, 0.58, 0.06, 0.059. This corresponds to option A, which is accurate when comparing decimal place values.

Explanation:

The question asks to arrange the given decimal numbers in order from largest to smallest. To do this, compare each decimal place value one by one from left to right. Starting with the first decimal place, select the largest digit to determine the largest number. Once the largest number is identified, move on to the next largest, and so on, until all numbers are ordered.

Comparing the whole numbers: 0.63, 0.58, 0.06, 0.059, we can see:

0.63 is the largest because it has the largest value in the tenths place (6), and the next number is 3.0.58 is the next largest because the tenths place is 5 and the hundredths place is 8, which is larger than the hundredths place of 0.59.0.06 is larger than 0.059 because when comparing numbers with the same digits leading up to the last place, the number with fewer decimal places is larger.

Therefore, the correct order from largest to smallest is 0.63, 0.58, 0.06, 0.059. The correct answer is option A: 0.63, 0.58, 0.06, 0.059.

Rita's score is 13 more than 2 times milan score. if we let y represent milan's score, write an algebraic expression for rita's score.

Answers

Final answer:

Rita's score is expressed algebraically by the expression 2y + 13, where y represents Milan's score.

Explanation:

Rita's score can be expressed algebraically in terms of Milan's score. Given that y represents Milan's score, the problem statement tells us that Rita's score is 13 more than 2 times Milan's score. So, we can write Rita's score as 2y + 13. To translate this into an algebraic expression, we start with Milan's score y, multiply it by 2 to get '2 times Milan's score', and then add 13 to get '13 more than 2 times Milan's score', which results in our final expression, 2y + 13.

This expression shows us how to calculate Rita's score based on any given value for Milan's score.

In geotown, there are 210 teenagers that own a tablet.This is at least 4/5 of all teenagers that live in geotown.What is the maximum number of teenagers who live in geotown?

Answers

Let x = the number of teenagers in Geotown.

At least 4/5 of x equals 210. Therefore
(4/5)x ≥ 210
Multiply each side by 5.
4x ≥ 210*5 = 1050
x ≥ 1050/4 = 262.5

Because x ≥ 262.5, therefore x = 263 (x must be an integer).

Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was \$43.25$43.25dollar sign, 43, point, 25. He had to pay a \$7$7dollar sign, 7 entrance fee and \$1.25$1.25dollar sign, 1, point, 25 for every minute he was on the trampoline. Write an equation to determine the number of minutes (t)(t)left parenthesis, t, right parenthesis that Raymond was on the trampoline.

Answers

7 + 1.25t = 43.25 <== ur equation
1.25t = 43.25 - 7
1.25t = 36.25
t = 36.25 / 1.25
t = 29 <== he was jumping for 29 minutes

Answer:

Answer:M=29

subtract 43.25 by 7 because it's a one time fee. But the 1.25 is for each minute so you subtract by 7 and you get 36.25. once you have 36.25 you divide it by 1.25. You should then get 29 mins.

Jan works from 30 to 40 hours per week during the summer. she earns $12.00 per hour. her friend rachel also has a job. rachel's pay for t hours is given by the function r(t) = 11t, where 20 ≤ t ≤ 30. find the domain and range of each function. compare their hourly wages and the amount they earn per week.

Answers

Jan earns between $360 and $480. While Rachel earns between $220 and $330. Jan's hourly wage is $12 and Rachel's is $11.

Final answer:

Jan's function has a domain of [30, 40] and a range of [$360, $480]. Rachel's function has a domain of [20, 30] and a range of [$220, $330]. Jan earns $12 per hour and can earn between $360 and $480 per week, while Rachel earns $11 per hour and can earn between $220 and $330 per week.

Explanation:

The domain of Jan's function is the range of hours she works per week, which is between 30 and 40, denoted by [30, 40]. The range of Jan's function is the amount of money she earns per week, which is calculated by multiplying her hourly wage ($12) by the number of hours she works (30 to 40 hours). So, the range of Jan's function is [$360, $480].

Similarly, Rachel's function is given by r(t) = 11t, where t represents the number of hours she works per week. The domain of Rachel's function is the range of hours she works per week, which is between 20 and 30, denoted by [20, 30]. The range of Rachel's function is the amount of money she earns per week, calculated by multiplying her hourly wage ($11) by the number of hours she works (20 to 30 hours). So, the range of Rachel's function is [$220, $330].

Comparing their hourly wages, Jan earns $12 per hour while Rachel earns $11 per hour. Comparing the amount they earn per week, Jan can earn between $360 and $480 per week while Rachel can earn between $220 and $330 per week.

1) Convert 3/5 to a decimal (show work)
2)Convert 3 8/10 to a decimal (show work)
3)Convert 5/9 to a decimal (show work)

Answers

1) To convert 3/5 to a decimal, we first multiply the numerator and denominator by 2 to obtain 6/10. One tenth is 0.1, so 6/10 is 6 times 0.1, or 0.6. 2) To convert 3 8/10 to a decimal, we see that 3 can be seen as a whole-number decimal, and 8/10 is 8 times 0.1, or 0.8. Adding these, we obtain 3.8. 3) We cannot write 5/9 as a decimal that terminates, but we can approximate 5/9 as a decimal. First, we multiply the numerator and denominator by 111, giving 555/999. Then we say that 999 is approximately 1000, so 555/999 is approximately 555/1000. Since 1/1000 is 0.001, then 555/999 is approximately 555 times 0.001, or 0.555.

Jamaal studied h hours for a big test. Karla studied one fourth as long. Write an algebraic expression for the length of time Karla studied. Use this expression to determine the length of time that Karla studied if Jamaal studied for 5 hours and 20 minutes.

Answers

Let's assign variable x to denote the number of hours for Karla to study. Since the relationship is relative to Jamaal's hours, the equation for Karla's hours would be:

x = (1/4)h

So, if Jamaal studied h = 5 h + (20 min* 1 h/60 min) = 16/3 or 5.333 hours. Thus, Karla's hours would be

x = (1/4)(16/3) = 1.33 hours or 1 hour and 20 minutes.

well if your sum is -18 then you know your answers are going to be negative numbers.

make x be your first unknown negative even integer. you want your negative x and then negative x minus two and negative x minus four

x1= x
x2= x-2
x3= x-4

you know all three need to equal -18

solve for x:
-18= -x + (-x-2) + (-x-4)

-18 = -x-x-2-x-4
-18+2+4= -3x
12=-3x

12/-3=x

-4=x

then plus x into the first problem.

x1= -4 = -4
x2= -4-2 = -6
x3= -4-4 = -8

so your integers would be -4, -6, and -8

−20 ≤ 59(F−32) ≤ −15

Answers

We take the value of F in the inequality by taking the inequalities in group. Let the first group be:

(1) -20 ≤ 59(F - 32)

Then, the second group would be,
(2) 59(F - 32) ≤ - 15

Calculating for the values of F,

(1) -20 ≤ 59F - 1888
1888 - 20 ≤ 59F
1868 ≤ 59F
F ≥ 31.66

(2) (59)(F - 32) ≤ - 15
59F - 1888 ≤ -15
59F ≤ 1873
F ≤ 31.75

The values of F are therefore,
31.66 ≤ F ≤ 31.75

To solve the inequality −20 ≤ 59(F−32) ≤ −15, divide by 59 and then add 32 to isolate the variable F, resulting in the range 31.661°F to 31.746°F.

Inequality Solution

Let's solve the compound inequality −20 ≤ 59(F−32) ≤ −15 step by step.

First, we need to isolate the variable term by dividing all parts of the inequality by 59.
−20/59 ≤ F − 32 ≤ −15/59.This simplifies to approximately:
−0.339 ≤ F − 32 ≤ −0.254.Next, we solve for F by adding 32 to all parts of the inequality:
32 - 0.339 ≤ F ≤ 32 - 0.254,
which simplifies to approximately:
31.661 ≤ F ≤ 31.746.

Therefore, the Fahrenheit temperature F is in the range of approximately 31.661°F to 31.746°F.
