A case of 12 jars of salsa weighs 180 ounces. How many ounces will 5 jars of salsa weigh?​

Answers

Answer:

75 ounces

Step-by-step explanation:

Divide 180 by 12 to see how much a single jar weighs

180/12 = 15

Multiply the weight of one jar by how many jars you need

15x5 = 75

Answer: 75 ounces

Step-by-step explanation:

The 12 jars combined weigh 180 ounces in total. We find the weight per jar by dividing 180 ounces by 12 which gives is 15 ounces per jar. We find the weight of 5 jars by multiplying 5 jars by 15 ounces. Here are the calculations as follows.

180÷12=1515x5=75

What is the circumference of a circle with a radius of eight inches

Answers

Answer:

50.24 inches

[tex] \: [/tex]

Step-by-step explanation:

It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.

[tex] \: [/tex]

To find the circumference of the circle we must know this formula first :

[tex]\\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \: Circumference_{(circle)}= 2 \pi r}}}}}} \: \: \bigstar \\ \\[/tex]

Where

r is the radius of the circle.

We'll take the value of π as 3.14

Now substituting the values in the formula :

[tex]\\{ \longrightarrow \qquad{ {{\sf{{ \: Circumference_{(circle)}= 2 \times 3.14 \times 8}}}}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ {{\sf{{ \: Circumference_{(circle)}= 3.14 \times 16}}}}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ { \pmb{\frak{{ \: Circumference_{(circle)}= 50.24}}}}}} \: \: \\ \\[/tex]

Therefore,

The circumference of the circle is 50.24 inches

Answer:

C = 50.24 in

Step-by-step explanation:

Given that,

→ Radius (r) = 8 in

Formula we use,

→ 2πr

The circumference of the circle will be,

→ 2πr

→ 2 × 3.14 × 8

→ 6.28 × 8

→ [ 50.24 in ]

Hence, the circumference is 50.24 in.

Step-by-step explanation:

x = 3x -28

x - 3x = -28

-2x = -28

x = 14

(3x - 18) + (6y - x - 10) = 180

3x - x -18 - 10 + 6y = 180

2x - 28 + 6y = 180

2x + 6y = 180 + 28

2(14) + 6y = 208

6y = 208 - 28

6y = 180

y = 30

A group of friends are canoeing along a river. They want to travel upstream 1.5 km, then travel back downstream back to their original starting point. The river has a current of 6km / h * r If the distance equation to find the time to travel upstream is time = and the equation to (velocitycurrenty distance travel downstream is time = ( velocity current) How fast should the canoe be traveling to complete the journey in 6 hours ? b. If the journey upstream ends up taking twice as long as the journey downstream, how fast did the canoe travel ?

Answers

Using the relation between velocity, distance and time, it is found that:

a) The canoe should be traveling at a rate of 37.5 km/h.b) The canoe traveled at a rate of 6.124 km/h.

What is the relation between velocity, distance and time?

Velocity is distance divided by time, hence:

[tex]v = \frac{d}{t}[/tex]

Item a:

1.5 km in 6 hours, with a velocity of vc - 6, in which vc is the velocity of the canoe and 6 km/h is the velocity of the current, so:

[tex]vc - 6 = \frac{1.5}{6}[/tex]

vc - 36 = 1.5

vc = 37.5.

The canoe should be traveling at a rate of 37.5 km/h.

Item b:

Upstream, the velocity is given by vc - 6, as it is against the stream, hence:

[tex]vc - 6 = \frac{1.5}{2t}[/tex]

[tex]t(vc - 6) = \frac{1.5}{2}[/tex]

[tex]t = \frac{1.5}{2vc - 12}[/tex]

Downstream, we have that:

[tex]vc + 6 = \frac{1.5}{2(\frac{1.5}{2vc - 12})}[/tex]

[tex]vc + 6 = \frac{1.5}{vc - 6}[/tex]

[tex]vc^2 - 36 = 1.5[/tex]

[tex]vc = \sqrt{37.5}[/tex]

vc = 6.124.

The canoe traveled at a rate of 6.124 km/h.

4) Look at this set of 5 numbers: 5 3 5 3 4

By how much would the mean increase if the number 8 replaced one of the 3's in the
set?

Answers

Answer: It increases by 1

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

Explanation:

To compute the mean, we first add up the numbers

5+3+5+3+4 = 20

Then divide by 5 since there are 5 numbers in the set

20/5 = 4

The mean is 4.

---------------

Now replace one of the '3's with 8 and recompute the mean

5+8+5+3+4 = 25

25/5 = 5

The mean is now 5.

The old mean in the previous section was 4.

The mean has increased by 1 since 5-4 = 1.

Side note: The increase from 3 to 8 is +5, which when dividing by 5, we're basically incrementing the mean by +1.

Answer:

1

Step-by-step explanation:

Mean=Sum of terms/ No.of terms

→5+3+5+3+4/5

20/5=4

If we replace 3 as 8 in one of the place values, Then:

5+3+5+8+4/5=25/5

5

Increment= 5-4=1
