A baker used the expression LaTeX: 9\left(15\:+\:Y\right)9 ( 15 + Y ) to show the number of muffins he needed to make. Emily said the expression has the same value as LaTeX: 90\:+\:Y90 + Y. Is Emily correct? Explain your answer.

Answers

Answer 1

Answer:

He wrongly distributed 9 over 15 and Y and got the wrong answer. The product of 9 and 15 is 135 not 90.

Step-by-step explanation:

Given the expression used by baker to show the number of muffins he needed to make as [tex]9\left(15\:+\:Y\right)[/tex], we are to check if the expression id equivalent to 90+Y

According to distributive law;

A(B+C) = AB + AC (This shows that A is distributed over B and C)

Applying distributive law on [tex]9\left(15\:+\:Y\right)[/tex]

[tex]9(15+Y) = 9(15) + 9(Y)\\9(15+Y) = 135 + 9Y[/tex]

From the result gotten, we can see that Emily is wrong because he wrongly distributed 9 over 15 and Y and got the wrong answer. The product of 9 and 15 is 135 not 90.

Define variables and write systems of equations for the situation. Solve using substitution. Suppose you want to join a video store. Big video offers a special discount card that costs $9.99 per year. With the discount card, each video rental costs $2.49. A discount card from Main Street Video cost $20.49 per year. With the Main Street Video discount card, each video rental costs $1.79. After how many video rentals is the cost the same? A. 17 B. 15 C. 9 D. 10. Please select the best answer from the choices provided.​

Answers

Answer:

(B) $15

Step-by-step explanation:

Big Video:  y = 2.49x + 9.99

Main Street:  y = 1.79x + 20.49

easiest way to solve would be to graph and find the point of intersection or set 2.49x + 9.99 and 1.79x + 20.49 equal to each other

2.49x + 9.99 = 1.79x + 20.49

subtract 1.79x from each side to get:

.70x + 9.99 = 20.49

subtract 9.99 from each side to get:

.70x = 10.50

divide each side by .70

x = 15

Write the slope-intercept form of the equation of the line through the given point with the given
slope. through: (1,4), slope = 9

Answers

Answer:

y = 9x - 5

Step-by-step explanation:

The slope is already given, so we just need to find the y-intercept.

Plug in 9 for m, 1 for x, and 4 for y in the equation y = mx + b.

4 = 9(1) + b

b = -5

Now that we know the y-intercept, we can construct the equation of the line.

y = 9x - 5

The cost of an ice cream cone is measured by the formula c=1/4x=3/4 where x is the number of scoops of ice cream and c is the cost.According to the how much should it cost to buy an ice cone without the ice cream

Answers

Question might have an error as it says 1/4x=3/4 as formula

Answer:

1/4

Step-by-step explanation:

Cost of ice cream cone is represented by the formula c=1/4x where x is the number of scoops of ice cream

Therefore the cost to buy to buy an ice cream cone without ice cream will be equal to 1/4. We can deduce this easily as we can see that x represents ice cream scoops, therefore cost of each cone is 1/4.

Mary has scored 78 , 60 , 82 , 94 , and 88 on her previous five tests . What score does she need on her next test so that her average ( mean ) is 80?​

Answers

Answer:

She needs to score 78 on her next test

Step-by-step explanation:

[tex]\frac{78+60+82+94+88+x}{6}=80[/tex]

Collect like terms;

[tex]\frac{402+x}{6}=80[/tex]

Multiply both sides by 6;

402 + x = 480

Subtract 402 from both sides;

Answers

Answer:

The had 8 drinks

Step-by-step explanation:

Here, we want to calculate the number of drinks they had

Let the total number of drinks be x

And the number of drinks they had be y

From the first part, we have that;

x-3(y) = 3

x -3y = 3

x = 3 + 3y •••••••(i)

Secondly

x-2(y) = 11

x = 11 + 2y •••••(ii)

We equate the two x

11 + 2y = 3y + 3

3y-2y = 11-3

y = 8

So what this mean is that they had 8 drinks

If a right angle triangle has a hypotenuse of length 13 units and a leg of length 7 units, what would be the length of the other leg?

Answers

Pythagorean theorem: A² + B² = C²
(7)² + B² = 13²;
49 + B² = 169;
B² = 130;
B = 11.40
The length of the other leg is 11.40.

The length of the other leg of a right angle triangle is, 10.95 units

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

A right angle triangle has a hypotenuse of length 13 units and a leg of length 7 units.

Now, By the Pythagoras theorem, we get;

⇒ Hypotenuse² = Perpendicular² + Base²

⇒ 13² = 7² + Base²

⇒ 169 = 49 + Base²

⇒ Base² = 169 - 49

⇒ Base² = 120

⇒ Base = √120

⇒ Base = 10.95 units

0; 1/4; 1/2; 1.5; 1.75 and 1 and 3/4 are the same.

Step-by-step explanation:

Answer:

First split it in half. That middle mark is 1.

Split each half in half. You should have 3 ticks evenly spaced.

First is 1/2, middle tick is 1, third tick is 1 1/2.

1/4 is inbetween 0 and 1/2.

Next is 1/2, which is the tick you made.

Next is 1.5, which is the third tick you made.

The last two, 1 3/4 and 1.75 mean the same thing. Both are exactly inbetween the third tick (1 1/2) and the last number which is 2.

Step-by-step explanation:

for part 2, just add in 3/4 exactly inbetween 1/2 and 1. and 1 1/4 which is between 1 and 1 1/2.

then you can add in 1/8 exactly inbetween 0 and 1/4

the fourth one is the one you made earlier which was 1 to split in half.

Answer:   The three sides are 15 cm, 25 cm, 30 cm

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

Explanation:

Let x be some positive real number

The sides are in ratio 3:5:6 which means we can multiply all three sides by x getting 3x:5x:6x

The sides of the triangle are 3x, 5x and 6x. The sides add up to the perimeter 70

3x+5x+6x = 70

14x = 70

x = 70/14

x = 5

With this x value, we can find the three sides

3x = 3*5 = 155x = 5*5 = 256x = 6*5 = 30

The three sides are 15 cm, 25 cm, 30 cm.

As a check:

15+25+30 = 40+30 = 70

and note how the ratio 15:25:30 reduces to 3:5:6 after dividing all three parts by the GCF 5

Both conditions are satisfied, so we have confirmed our answers.

Answer:

5

Step-by-step explanation:

(3x) + (5x) (6x) = 70

=     14             = 70

        70/14

=     5
