5 x 47

Answers

Answer 1
Final answer:

To find the product of 5 x 47 using the Distributive Property, we can break down the second number into its tens and ones digits, distribute the first number to both parts, and simplify the expression.

Explanation:

To find the product of 5 x 47 using the Distributive Property, we can break down the second number, 47, into its tens and ones digits.

47 can be written as 40 + 7.

Then, we can distribute the 5 to both parts: 5 x 40 + 5 x 7.

This simplifies to 200 + 35, which equals 235.

The surface area of a triangular prism is 648 square units.

What is the surface area of a triangular prism?

The surface area of a triangular prism is

= (perimeter of the base triangle × length) + (2 × base area of the triangle)

Given, the area of the base triangle is

= (1/2) × y × h square units

= (1/2) × 18 × 12 square units

= (1/2) × 216 square units

The perimeter of the base triangle is

= (x + x + y) units

= (15 + 15 + 18) units

= 48 units

Length = z = 9 units

Therefore, the surface area of the triangular prism is

= [(48 × 9) + 2 × (1/2) × 216] square units

= 648 square units

Which linear inequality is represented by the graph?

Answers

for this one, all you have to do is test out those points and see if you get a valid answer!! it's easier than it looks.

y < 0.5x + 2

then, you can either find these points on your graph to check them (easier for most), but some people prefer the other method which is just taking your answer choices and plugging them in:
(-3, -2)
-2 < 0.5(-3) + 2
-2 < -1.5 + 2
-2 < 0.5
then, you just ask yourself "is that true?" is -2 less than 0.5? and the answer is yes, that's true, so this point is a solution.

the same process repeats with the rest of them, but:
(-3, 2) is a solution.
(-2, 1) is not a solution.
(-1, -2) is a solution.
(-1, 2) is not a solution.
(1, 2) is a solution.
(1, -2) is not a solution.
(1, 2) is a solution.

Answer:

The correct options are 1, 3, 5 and 6.

Step-by-step explanation:

The given inequality is

[tex]y<0.5x+2[/tex]

A point is the solution of a linear inequality, if it satisfy the inequality.

The given point is (-3,-2). Check whether this is a solution or not.

[tex](-2)<0.5(-3)+2[/tex]

[tex]-2<0.5[/tex]

This statement is true. Therefore (-3,-2) is a solution.

The given point is (-2,1). Check whether this is a solution or not.

[tex](1)<0.5(-2)+2[/tex]

[tex]1<1[/tex]

This statement is false. Therefore (-2,1) is not a solution.

The given point is (-1,-2). Check whether this is a solution or not.

[tex](-2)<0.5(-1)+2[/tex]

[tex]-2<1.5[/tex]

This statement is true. Therefore (-1,-2) is a solution.

The given point is (-1,2). Check whether this is a solution or not.

[tex](2)<0.5(-1)+2[/tex]

[tex]2<1.5[/tex]

This statement is false. Therefore (-1,2) is not a solution.

The given point is (1,-2). Check whether this is a solution or not.

[tex](-2)<0.5(1)+2[/tex]

[tex]-2<2.5[/tex]

This statement is true. Therefore (1,-2) is a solution.

The given point is (1,2). Check whether this is a solution or not.

[tex](2)<0.5(1)+2[/tex]

[tex]2<2.5[/tex]

This statement is true. Therefore (1,2) is a solution.

Thus the correct options are 1, 3, 5 and 6.

Television Videl watched 6 times as many hours of television over the weekend as Dineen. Together they watched a total of 14 hours of television. How many hours of television did each person watch over the weekend

Answers

We can make this into an equation. 6 times as many means Videl watched 6 times as many as Dineen, and Dineen watched x hours.
Thus, 6x+x=14. Isolate and solve for x.
7x=14
Divide by 7 on both sides.
x=2.
Videl watched 6*2 hours, or 12 hours of TV.
Dinnen watched 2 hours of TV.

The number of hours of television that they both watched will be 2 hours and 12 hours respectively.

Let the number of hours used by Dineen be x.

Therefore, the number of hours that Videl watched will be 6 × x = 6x

Therefore, based on the information given, the number of hours of television watched will be:

6x + x = 14.

7x = 14.

x = 14/7 = 2 hours.

Therefore, 6x = 6 × 2 = 12 hours

Ellen walks dogs on weekends she gets paid $ 8.50 per hour each day she works 5 hours and 45 minutes does she earn more or less than $85 in one weekend? how much more or less explain.

Answers

$8.50 * 5 = $42.50
45 mins -> $8.50 / 60 * 45 = $6.37

She will earn less than $84 in one weekend because $42.50 + $6.37 = $48.87

Answer:

Ellen earns $159.375 more than $85.

Step-by-step explanation:

We have been given that Ellen walks dogs on weekends she gets paid $ 8.50 per hour. Each day she works 5 hours and 45 minutes.

[tex]\text{45 minutes}=\frac{45}{60}\text{ hour}[/tex]

[tex]\text{45 minutes}=0.75\text{ hour}[/tex]

We know that each week has 5 working days.

[tex]\text{Hours worked each week}=5\times 5.75\text{ hours}[/tex]

[tex]\text{Hours worked each week}=28.75\text{ hours}[/tex]

[tex]\text{Earnings each week}=\$8.50\times 28.75[/tex]

[tex]\text{Earnings each week}=\$244.375[/tex]

Since $244.375 is greater than $85, therefore, Ellen earns $159.375 more than $85.

How do you solve equations using multiplication and division

Answers

In order to move a number that is multiplied or divided by the variable, you must do the inverse to both sides. That means, if the number is multiplied, you must divide it by both sides. If it's divided, you must multiply it by both side. steps so that you can apply them to more complex problems.

Hope This Helps
To properly answer this I would need to know what the problem is.

However, to multiply you must figure out how many times you add one number to itself. For example, 3 x 4 is three added to itself four times. 3 x 4 = 12 and 3 + 3 + 3 + 3 = 12.

To divide you must figure out how many times one number can go into another. For example, 15 divided by 3 is seeing how many times 3 must be added to itself to equal 15. 15 divided by 3 = 5 and 3 + 3 + 3 + 3 + 3 = 15. (There are five threes added together to get 15, which is how we know the answer to the equation is 5.)

I'm not entirely sure if this is what you wanted or not, again, I would need to see the entire problem to figure this out.
