Answer:

The first restaurant is a better deal.

Step-by-step explanation:

First restaurant: Let's say there are 2 people. 28 x 2 = 56. You would have to pay $56 for 2 people.

Second restaurant: Let's say there are 2 people. The graph says that you would have to pay $60 for 2 people.

Therefore, the first restaurant is a better deal.

The first option is cheaper if that’s what you’re asking.
It’s cheaper because it has a smaller slope so overall will have a lower price than the other option.

Greatest to least 2/7, 1/4, 2/9

Stella [2.4K]

1/3; 2/7; 2/9

Lets find least common multiple

The least common multiple is 63

1/3 --> 21/63

2/7 --> 18/63

2/9 --> 14/63

As you can see I am correct, but I found the LCM by multiplying 1/3 by 21 to get to 63 and the numerator as well

Which shows the expression below simplified? 0.00048 - (3.4 × 10-5) A. 4.46 × 10-4 B. 3.39952 × 10-5 C. 4.46 × 10-5 D. 1.4 × 10-

MakcuM [25]

Option C

The simplified form of given expression is $4.46 \times 10^{-4}$

Solution:

Given that we have to simplify the expression shown below

$0.00048 - (3.4 \times 10^{-5})$

Let us first convert 0.00048 to scientific notation

Steps to follow:

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

$0.00048 = 4.8 \times 10^{-4}$

So the given expression becomes,

$\rightarrow 4.8 \times 10^{-4} - 3.4 \times 10^{-5}$

Let us make the exponent of second term as -4

$\rightarrow 4.8 \times 10^{-4} - 0.34 \times 10^{-4}$

Take $10^{-4}$ as common term,

$\rightarrow 10^{-4} (4.8 - 0.34)$

$\rightarrow 4.46 \times 10^{-4}$

Thus option C is correct

Elena plans to ride her bicycle 5 miles to a park and then ride several times

Aneli [31]

Option A

Elena need to ride around the loop four or more times

Solution:

Given that Elena plans to ride her bicycle 5 miles to a park and then ride several times around a loop in the park that is 3 miles long

Then she will ride the same way home

She wants to ride a total of at least 22 miles

Given inequality is:

3t + 10 > 22

Where "t" is the number of times Elena rides around the loop

Solve fot "t" in given inequality

3t + 10 > 22

Subtract 10 both sides

3t + 10 - 10 > 22 - 10

3t > 12

Divide by 3 both sides

t > 4

The solution is all real numbers greater than or equal to 4

Which means 4 or more times

Therefore, Option A is correct.
