Answer:
24 days.
Step-by-step explanation:
Fresh produce is delivered to a restaurant every 4 days.
Every 6 days, the restaurant receives a delivery of dried and canned goods.
Now , if the produce and dried and canned goods were delivered today
So, they are all delivered to the restaurant on the same day again after days :
=6x4
=24

if you do this and explain how to do it i will rait you 5 stars and give you a brainlyieist it has to be simplify 2(5+3x)+(x+10)

Answers

Answer:

20+7x

Step-by-step explanation:

you'd multiply 2 by 5 and 2 by 3x which will give you 10+ 6x; Then add the others : 2(5+3x)+(x+10) would be 10+6x+x+10 so its 20+7x.     .

Answer: 30+4x or 2(15+2x)

Step-by-step explanation:

So the way you would do this is actually kinda simple.

You question is 2(5+3x)+(x+10)

First you wanna add the common number together. So you would change you problem to

2(5+10)+(x+3x)

Now you want to start by solving 2(5+10)

The two on the outside means you multiply so you would do

2x5+2x10 you would get the answer 10+20=30

Now you’re equation is 30+(x+3x)

So now you need to do (x+3x) in this case we would make X=1

So you do 1+3(1) or 1+(3x1) And you get 4x

Now you have the answer 30+4x or to siplfy it you get 2(15+2x)

Hope this helps you xoxo

In a hand of playing cards, what is the probability that all five are of the same suit?

Answers

Answer:

How many five-card hands dealt from a standard deck of 52 playing cards are all of the same suit? If a random hand is dealt, what is the probability that it will have this property?

Would the probability be:

(135)∗(41)(525)

Answer:

0.1965%

Explanation:

Because 13/52 are the same suit, we find the probability of 5 cards of the same suit (without replacemennt).

13/52=0.25

12/51=0.235

11/50=0.22

10/49=0.204

9/48=0.188

*multiply sums*

=0.0004957

*multiply by 4 since there are 4 different suits*

=0.001965x100=~0.1965%

10^-2 + 8 round the coefficient to two decimal places​

Answers

Answer:

I believe it is .0801

Step-by-step explanation:

- A negative exponent will always turn into a fraction

- First change it to a fraction

1/10^2

- Simplify the exponent

10 times 10 = 100

- Change the fraction

1/100 or in decimal form which is 0.01

- Now the addition

8 + 0.01 = 8.01

- Move decimal to two decimal places

.0801

Answer:    .0801 is what I got because the way I understand it 10^(-2) + 8 =8.01 and you said round it to the coefficient to 2 decimal places. so I moves the 8 over 2 times because 8 is the coefficient and I got .0801

Answer:

43%

Step-by-step explanation:

Find What is the decrease percentage for 350 to 200?

Step by step workout

step 1 Address the formula, input parameters & values

Formula :

Difference

Initial Value

x 100 = Percent Decrease (%)

Initial Value X = 350 & New Value Y = 200

Decrease = (X - Y)

(350 - 200)

350

x 100 = ?

step 2 Apply the values in the percentage decrease {(X - Y)/X x 100} formula

=(350 - 200)

350

x 100

=150

350

x 100

= 42.8571%

(350 - 200)

350

x 100 = 42.8571%

The percentage reduction can be written as 57.1429% of 350.

42.8571 percent decrease (%↓) or reduction from 350 is 200.

If you round it you get 43%

2.) Kim rented a bounce house for a party. There was a one-time charge of $100, plus an hourly rate of $35. Her total cost for the night was $327.50. For how many hours did Kim rent the bounce house?
h = the # of hours Kim rented the bounce house
Write the equation to represent this situation. (Do not use any spaces in your equation)

Answers

Answer:

1. x=43miles-20miles

2.h=($327.50-$100)/35

Step-by-step explanation:

1. The answer is x=43miles-20miles. This is because Joy ran more miles than Olivia. So to find the time olivia ran you say 43 minus 20.

2. The answer is h=($327.50-$100)/35. This is because you remove ( subtract ) the one time charge in order to get the hour charges. Then to find the number of hours Kim rented the bounce house you divide by 35 because this is the price for an hour.

A circle has a diameter of 20 ft. What is the diameter? *

Answers

Since the question provided the diameter instead of radius, the diameter is 20 feet

Answer: well the diameter would be 20ft. If you meant to ask for the circumference then its 62.857ft

Step-by-step explanation:

Diameter of a circle is 20​ feet.

Hence it's Radius = 20/2 = 10 ft

We know circumference = 2πr

Circumference = 2 × 22/7 × 10 ft

Circumference = 44 × 10/7= 440/7

Circumference = 62.857 ft
