Jordan and Dajia are both completing homework on Deltamath. Jordan started yesterday and completed three problems and is solving the problems at a rate of 2 questions per minute. Dajia waited until today to get started and is solving the problems at a rate of 3 questions per minute. After how many minutes will they have solved the same number of questions?

Answer:

a. 29

b. 0.25

c. 75

d. 64

Step-by-step explanation:

You just basically plug in the number for x and solve.

Given:

Perimeter of a parallelogram = 64 cm

Length = 3 times larger than the width

To find:

The length of the parallelogram.

Solution:

We know that, the perimeter of the parallelogram is:

[tex]P=2(l+w)[/tex]

Where, l is length and w is width of the parallelogram.

We have, l = 3w and P=64.

So,

[tex]64=2(3w+w)[/tex]

[tex]64=2(4w)[/tex]

[tex]64=8w[/tex]

Divide both sides by 8.

[tex]8=w[/tex]

Now,

[tex]l=3w[/tex]

[tex]l=3(8)[/tex]

[tex]l=24[/tex]

Therefore, the length of the parallelogram is 24 cm.

Answer: [tex]\frac{40}{3}\ \text{hours}[/tex]

Step-by-step explanation:

Nancy can do typing job in 8 hours

i.e. in 1-hour nancy can  [tex]\frac{1}{8}[/tex] part of work

Together they can do that work in 5 hours

or in 1 hour [tex]\frac{1}{5}[/tex] part of work is done

suppose Carole takes x hours for the work

so, in 1 hour [tex]\frac{1}{x}[/tex] part is done

If both work together for 1 hour then we can write

[tex]\frac{1}{8}+\frac{1}{x}=\frac{1}{5}[/tex]

[tex]\frac{1}{x}=\frac{1}{5}-\frac{1}{8}[/tex]

[tex]x=\frac{40}{3}\ \text{hours}[/tex]

Answer:0.16625

Step-by-step explanation:

Answer:

~6.02

Step-by-step explanation:

It's a ratio

3.99 : 24

1 : 6.015037593984962

or....

1 : 6.02

I got my answer as "6.015037593984962" because from 3.99 to 1, you need to divide by 3.99 (any number divided by itself gives you 1), and so when you do something to one side, you do it to the other. So then I did 24 divided by 3.99 and i got "6.015037593984962". Since that number is big, I suggested rounding it up to the nearest hundredth, and that is at the number "1". Since the next number after "1" is "5" I rounded up "1" to "2" because....4 or less, let it rest, 5 or more, let it sore. And since it's the number 5, I rounded up the 1 to 2. And so I converted "6.015037593984962" to "6.02".

Hope this helped!

Answer:

False

Step-by-step explanation:

Notice how the negative symbol is outside the first number and inside the first number. If the negative symbol is outside the absolute value, the number will remain negative. If the negative symbol is inside the absolute value, the number will turn to positive.

Answer:

b. 1/9

Step-by-step explanation:

1. 1/6 is the probability of rolling 6

2. 4/6 is the probability of rolling less than 5

3. Multiply them: [tex]\frac{1}{6} x\frac{2}{3}[/tex]

4. Answer: 1/9

The probability of getting a 6 on the first roll, then a number less than 5 on the second roll should be option b.

since

1/6 should be considered as  the probability of rolling 6

And, 4/6 is the probability of rolling less than 5

So [tex]= 1\div 6 \times 2\div 3[/tex]

= 1/9

Hence, the option b is correct.

Answer:

4.9ft^2

Step-by-step explanation:

7.85 ft is the circumference of the tire (circle), so [tex]\pi[/tex]d = 7.85.

7.85/[tex]\pi\\[/tex] = 2.5, the diameter is 2.5, so the radius is 1.25.

[tex]\pi[/tex]r^2 is the formula for the area, so [tex]\pi[/tex]*1.25^2 = 1.5625[tex]\pi[/tex], which is 4.906, which rounded to the tenth is 4.9.

Answer:

(2, 2) ; (4, 4) ; (6, 6)

(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

Step-by-step explanation:

(1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)

Evaluating the ratio of each pair :

(1, 2) = 1/2 = 0.5

(2,3) = 2/3 = 0.67

(4, 7) = 4/7 = 0.57

(2,2) = 2/2 = 1

(4, 4) = 4/4 = 1

(6, 6) = 6/6 = 1

(3, 1) = 3 /1 = 3

(4, 1) = 4 / 1= 4

(5,1) = 5 / 1= 5

(4, 1) = 4 / 1 = 4

(8, 2) = 8/2 = 4

(12,3) =12/3 = 4

(2, 1) = 2/1 = 2

(4,3) = 4 / 3 = 1.33

(5, 4) = 5 / 4 = 1.25

Pairs with equivalent ratios :

Ratio of 1;

(2, 2) ; (4, 4) ; (6, 6)

Ratio of 4:

(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

Answer:

The 100th term will be;

10(0.5)^99

Step-by-step explanation:

Firstly, we need the common difference and the first term

The first term is 10

The common difference is 5/10 = 1/2

Now, the formula for the nth term of a geometric sequence is;

ar^n-1

So, for the nth term, we have;

ar^(100-1)

= ar^99

So we have

10(1/2)^99

The answer is the Veggie Sandwich

Step-by-step explanation:

Given that there are four large submarine Sandwiches in a party and all of them are of the same size.

Some parts of each of them were eaten during the party. We are to find the Sandwich that has the least amount left.

The fractions of the Chicken Sandwich(C), Tuna Sandwich(T), Roast beef Sandwich(R) and the Veggie Sandwich(V) that were eaten during the party are given by

Therefore, the fractions of the Sandwiches that left will be

Out of the four fractions, V' is the smallest, so the Veggie Sandwich has the least amount left.
