Answer:

1. 5

2. 1.29

3. 9.90

Step-by-step explanation:

They are buying 5 of each thing, so multiply it by 5.

The diced tomatoes cost $1.29.

When you solve the equation, you get 9.9. Convert that to money, and you have $9.90

Answer:

No,the price is not within their budget.

Step-by-step explanation:

Because if you take 144 times 76 you get 10,944 which goes past their budget of 10,000

Answer:

They are over budget by $1,232.

Step-by-step explanation:

They want to replace 144 computer monitors each for $76.

$76 * 144 = $11,232

Their budget is $10,000 so they would be over budget by:

$11,232 - $10,000 = $1,232

Answer:

y = 12/7

Step-by-step explanation:

Slope = (change in Y) / (change in x)

-1/7 = (y - 2) / (3 - 1)

-1/7 = (y - 2)/2

Cross multiply:  -1(2) = 7(y - 2)

                             -2 = 7y -14

                        -2 + 14 = 7y

                                12  = 7y

                               12/7 = y

Let's find y

[tex]\\ \sf\longmapsto m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \sf\longmapsto \dfrac{-1}{7}=\dfrac{y-2}{3-1}[/tex]

[tex]\\ \sf\longmapsto \dfrac{-1}{7}=\dfrac{y-2}{2}[/tex]

It is observed that point (18, 206) does not lie on the line. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equation is given below.

y = 12x

Where 'y' represents the number of gallons of water in the pool and 'x' represents the number of minutes the water runs.

The equation is drawn below.

From the chart, it is seen that point (18, 206) doesn't lie on the line. Then the right choice is D.

Answer: 4.3 × 10^6 meters, and 4.3 × 10^9 millimeters.

Explanation: In order to find the scientific notation of a large number, you want to move the decimal point to the left until you only have one digit to the left of the number, then you can count the spaces you have moved, and this will make the power of 10 that you'll add to the end. This seems a little confusing, but let's look at it through the example.

Step 1) Move the decimal point to the left until there's only one digit to the left of the decimal:

4,300,000 turns into 4.300000

Step 2) Count the number of digits you've moved.

Above, we moved 6 spaces to the left.

Step 3) Add the decimal to the front, and then 10^the number of spaces you moved

4.3 (from step one) × 10^6 (from step two)

= 4.3 × 10^6

It works the same way for the millimeter question, just convert meters into millimeters before you start the problem, and then solve it using the steps above! I hope this helped you :)

The scientific notation in meters and millimeters are

- 4.3 x [tex]10^{6}[/tex] meters

- 4.3 x [tex]10^{9}[/tex] millimeters

It is a way of writing very large or very small numbers where a number between 1 and 10 is multiplied by a power of 10.

Example:

310,000,000 can be written in scientific notation as 3.1 ✕ 10^8.

We have,

Distance = 4,300,000 meters

1 meter = 1000 millimeters

So,

4,300,000 meters = 4,300,000,000 millimeters

We can write 4,300,000 in scientific notation as:

= 4.3 x [tex]10^{6}[/tex] meters

We can write 4,300,000,000 millimeters in scientific notation as:

= 4.3 x [tex]10^{9}[/tex] millimeters

Thus the scientific notation in meters and millimeters are

- 4.3 x [tex]10^{6}[/tex] meters

- 4.3 x [tex]10^{9}[/tex] millimeters

Step-by-step explanation:

Options D and E are out because it clearly says " bags can only carry up to 480 pound" and those are saying it can hold more than 480

Options B and C have a dashed line. If it has a dashed line that means that it is < or > and it is not because it says "up to" up to means it CAN hold exactly 480

So the only right answer would be Option A

Answer:

steps below

Step-by-step explanation:

Set    log x = a     and     log y = b

x = 10ᵃ     and       y = 10ᵇ

if a>b      10ᵃ > 10ᵇ

so  x > y

x = 57²⁰¹⁸              y = 51²⁰²⁰

log x = log 57²⁰¹⁸ = 2018 * log 57 = 3543.36 :  (a)

log y = log 51²⁰²⁰ = 2020 * log 51 = 3449.29 : (b)

3543.36 > 3449.29       log x > log y    

x > y:        57²⁰¹⁸ > 51²⁰²⁰

Answer:

2 1/4

Step-by-step explanation:

First, for adding, subtracting, and comparing fractions, it is good to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators = LCM ⇒ (2, 4) = 4. We should do = three halfs + three quarters = nine quarters.  Thus, 2 1/4 or 2.25 is the answer.

1 1/2 + 3/4 = 9/8 = 2 1/4 or 2.25

Answer:

p = 7

Step-by-step explanation:

i think there's a proper equation to solve these kinds of problems but you can think about numbers times 6 (1x6 = 6, 2x6 = 12, 3x6 = 18,...)

The value of p will be 7.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

p is a whole number.

And, 6p is greater than 40 and less than 45.

Now,

Since, 6p is greater than 40 and less than 45.

Hence, We can formulate;

⇒ 40 < 6p < 45

Solve for p as;

⇒ 40 < 6p < 45

Divide by 6, we get;

⇒ 40/6 < 6p/6 < 45/6

⇒ 6.67 < p < 7.5

Since, p is a whole number.

Hence, The value of p = 7

Thus, The value of p will be 7.
