Does the tallest can always hold the greatest volume? Explain your answer!

Complete question is;

Alyssa took a math test with 20 questions and she answered 16 questions correctly. In order get an A, she needs to answer at least 90 percent of the questions correctly.

A) Did Alyssa get an A on this math test? Explain.

B) How many questions would Alyssa need to answer correctly in order to get an A?

C) On the same exam, Alyssa's friend Jessie answered three times more questions correct than incorrect. Who got a higher percentage of the test questions correct, Alyssa or Jessie

Answer:

A) she didn't get an A because she scored less than 90%.

B) She will need to answer 18 correctly to get an A.

C) Alyssa had a higher percentage.

Step-by-step explanation:

A) Alyssa answered 16 out of 20 questions correctly.

Converting this to percentage gives;

16/20 × 100% = 80%

Now,we are told she needs at least 90% correct answers to get an A.

She scored 80% which is less than 90% mark of A, therefore she didn't get an A.

B) Let the number of minimum questions to answer correctly out of 20 be x.

Thus, since it is 90%.

Then;

x/20 × 100% = 90%

making x the subject;

x = 90 × 20/100

x = 18

She will need to answer 18 correctly to get an A.

C) her friend Jessie answered three times more questions correct than incorrect.

This means for every 4 questions answered, she had 3 correct and 1 incorrect.

Thus,

For 4 questions she had 3 correct answers, then for 20 questions, she will have: 20 × 3/4 = 15 correct questions

Which corresponds to;

15/20 × 100% = 75%

Thus, Alyssa had a higher percentage.

Answer:

If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.

Step-by-step explanation:

Answer:

Down below is the answer.

Step-by-step explanation:

So, lets remember that the pythagreon theorm is only useable in right traingles.

The formula for the pythagreons theorm is A^2+B^2=C^2

So basically, if this is not a right triangle, the two sides(4ft^2 and 3ft^2) will be equivelent to 5ft^2.

Lets solve the pythagroens theorm and plug in our values:

4^2+3^2=5^2

Now lets use the square roots:

16+9=25

COmbine the two numbers:

25=25

This is correct!

So yes, this is a right triangle.

HOpe this helps! :)

Answer:

the cost of orange is 170

Answer:

One orange costs $1.45.

Step-by-step explanation:

Since there are two variables, you have to set up a 2 variable equation.

Let's let a = apples and o = oranges.

So, we can set up this problem as:

5a + 4o = 11.80

1a  + 6o = 9.90

You can solve a 2-variable equation using either elimination or substitution. Here, I think it's easier to use substitution. To do that we have to substitute one variable with an equation that uses only the other so that we only have one variable.

We can manipulate our second equation so that it is:

a = 9.90 - 6o

Then, we can plug this in for a in the first equation. So,

5 (9.90 - 6o) + 4o = 11.80

49.5 -30o +4o = 11.80  (Distribute the 5)

49.5 - 26o = 11.80  (Combine like terms)

-26o = -37.7 (Subtract 49.5 from both sides)

o = 1.45 (Divide by -26)

o = 1.45

So, an orange costs $1.45.

Answer:

es una pregunta o necesitas eso traducido al inglés ¿?

Answer:

Clare starts with:

a*x^2 + b*x + c = 0

And she gets to:

(2*a*x + b)^2 = b^2 - 4*a*c

Now we want to show the final steps to solve the equation (isolating x)

First, we apply the square root to both sides:

[tex]\sqrt{(2*a*x + b)^2} = \sqrt{(b^2 - 4*a*c)}[/tex]

Because the square root has two solutions, (one negative and one positive), we will write:

[tex]2*a*x + b = \pm \sqrt{b^2 - 4*a*c}[/tex]

Now we subtract b in both sides:

[tex](2*a*x + b) - b = \pm \sqrt{b^2 -4*a*c} - b[/tex]

[tex]2*a*x = \pm \sqrt{b^2 -4*a*c} - b[/tex]

Now let's divide by 2*a in both sides:

[tex]2*a*x/(2*a) = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

[tex]x = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

Answer:

32.2

Step-by-step explanation:

70 divided by 100 times 46

Answer:

1)

Perimeter=24 inches

Area= around 43.46 inches

Step-by-step explanation:

1) Perimeter = 3in * number of sides

Perimeter = 3*8 = 24

Area= 2(1+ square root of 2) length of one side squared

=42.46

2)

Perimeter = 24

Area= 43.46 inches squared- 3inches

3)

Perimeter = 24

Area= 43.46- triangle area

triangle area = height x base /2

Height = 3, we can compare it.

Base = 3

Triangle = 9/2

Area = 43.46- 4.5

Area =38.96

Can't see 4 and 5 for some reason

6)

Perimeter =  30

Area = 61.94

Answer:

C

Step-by-step explanation:

1. Absolute values are in the shape of a V, so the answer is automatically C.

2. If you did not know that, you can see that the graph is a function because it passes the vertical line test. This rules out option A. By looking at the graph, you can see it passes the x-axis twice, meaning that it has 2 x-intercepts. This rules out option B. X-intercepts always have a y-coordinate of 0, so we can rule out option D. The only option left after this is C.

Answer:

C

Step-by-step explanation:

For one, it's negative so all positive answers can be eliminated.

Secondly, the y axis is hit on positive 3. No point even hits negative 3.

Knowing that, the only choice left is C.

Answer:

5.x^8.y^3

Step-by-step explanation:

15.x^10.y^5.z^2 ÷ 3.x^2.y^2.z^2

= 15/3. x^(10-2). y^(5-2). z^(2-2)

= 5.x^8.y^3.z^0

= 5.x^8.y^3

Answer:

Rectangle is the correct answer hope it helps you have a great day keep smiling be happy stay safe ☺️

A rectangle is a special type of parallelogram. Any parallelogram has two pairs of opposite parallel sides. A rectangle is a parallelogram where all four angles are the same, and all four angles are 90 degrees.

Keep in mind that not all parallelograms are rectangles, but any rectangle is always a parallelogram.

In slight contrast, a trapezoid has exactly one pair of parallel lines, while the other pair of opposite sides are not parallel. Triangles of any kind can be ruled out because they don't have any parallel sides at all.

Answer:

By rounding

Step-by-step explanation:

48 % means 48 percent which 48 out of 100.

48% of 1220

= 48/100*1220

= 0.48*1220

=585.6 which is almost equal to 600

1) By rounding

Now if we round 48%  we get  50 % as 8 > 5 and 1 is added to 4 making it 5 in tens place leaving 0 in unit's place.

So 50% of 1220

0.50*1220= 610

Again rounding 610 would give 600 as 1 is less than 5 and we drop it out from the tens place leaving zero behind.

2) Complementary

IF we subtract 48% from 100% we get 52%.

So 52% of 1220 would be 634.4

IT again can be rounded in 2 ways Either 52% can be rounded to 50% and 634.4 can be rounded to 600.

Both would give 600
