You told your friend that you could eat 5/8 of a large pizza. If you only ate 1/2 of what you said you could eat, what fraction of a large pizza did you eat?

Answers

Answer:

5/16

Step-by-step explanation:

Given that:

Fraction of claim = 5/8

Amount actually eaten = 1/2 of claim

Amount actually eaten = 1/2 * 5/8 = 5/16

Fraction of large pizza actually eaten is 5 /16

Use the property of parallelograms to solve for the missing variable

Answers

Answer:

x = 30, y = 6

Step-by-step explanation:

Here, we want to use the property of parallelograms

mathematically, the lengths of the parallel sides are equal

This mean:

2y + 3 = y + 9

2y - y = 9-3

y = 6

To get x;

Angles that face each other are supplementary; meaning they add up to 180

Thus, we have that

4x + 2x = 180

6x = 180

x = 180/6

x = 30

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the acute angle of the given triangle is 28.07 degrees.

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A triangle has sides with lengths 8, 15, and 17.

By Pythagoras theorem, we have

  H² =  P² + B²

 17² = 8² + 15²

289 = 64 + 225

289 = 289

The dimension of the triangle satisfies the Pythagoras theorem. Hence the triangle is a right-angle triangle.

Then the acute angle will be

[tex]\rm \theta =Sin ^{-1} \dfrac{8}{17}\\\\\theta = 28.07^o[/tex]

Thus, the acute angle of the given triangle is 28.07 degrees.

If a scuba diver swam from the surface at −1212 feet per minute, for 412 minutes, what would be the diver’s change in elevation?

Answers

Answer:

-1212 feet/min * 412 min = -499314 feet

Step-by-step explanation:

if you have a speed, or in this case velocity since the measurement has a definite direction,  and time you can multiply them together to get the distance.  Some easy examples, 10 feet per second for 1 second is 10 feet, hopefully that logically makes sense as well.  i you are going 10 feet in 1 second, then after 1 second you went 10 feet.  after 2 seconds it's 20 seconds and so on

Here we have -1212 feet per minute for 412 minutes.  just to establish things, 1 minute would be -1212 feet, here the negative means below the surface, sometimes measurements will have that.  Anyway, 2 minutes would get -2424, and so on.  So it should make sense to multiply them.

-1212 * 412 = -499314

With units, you also have to pay attention to what might cancel out.  You treat different units like variables.  so -1212feet per minute looks like -1212 feet/min where feet and min are basically variables.  Similarly 412 minutes is 412 min.  So if you picture multiplying these, you get -1212 feet/min * 412 min.  In this scenario the mins cancel each other out, since everything s being multiplied.  so like if you had x/y * y you would just get x, or 2/3 * 3 gets just 2.  So this is another way to know what to multiply by.

feet/min has min in the denominator and we want feet, so we need to multiply by something that just has min as its units.  Anyway, that let's you know it's -499314 feet

The drivers change in elevation is 499,344 feet in 412 minutes

Given:

Distance travelled per minute = −1212 feet

Time travelled = 412 minutes

Change in elevation = Distance travelled per minute × Time travelled

= −1212 feet per minute × 412 minutes

= 499,344 feet

Therefore, the drivers change in elevation is 499,344 feet in 412 minutes

Given the arithmetic sequence -9,-4, 1, 4,... Which term has a value of 166?

Answers

Answer:

36th term

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 9 and d = - 4 - (- 9) = - 4 + 9 = 5 , then

[tex]a_{n}[/tex] = - 9 + 5(n - 1) = - 9 + 5n - 5 = 5n - 14

Equate the nth term to 166 and solve for n

5n - 14 = 166 ( add 14 to both sides )

5n = 180 ( divide both sides by 5 )

n = 36

Here a₁ = - 9 and d = - 4 - (- 9) = - 4 + 9 = 5 , then

Equate the nth term to 166 and solve for n

The average grade Jared received on 4 tests was 94. If he drops his lowest test grade of 85, what will his new average be?

A.72.75
B.76
C.89.5
D.97

Pls help TT

Answers

Answer:

total points on the 4 tests- 94x4= 376

376- 85= 291

291/3= D. 97

Answer:

D. 97

Step-by-step explanation:

x = sum of 4 test grades Jared received

[tex]\frac{x}{4} = 94[/tex]

x = 376

If he drops lowest test grade of 85, then subtract 85 from Jared's sum of all test grades:

x - 85 --> 376 - 85

= 291

Now that one of his test grades are not considered, this means there are only 3 test grades to consider.

291 must be divided by 3 to get the average:

[tex]\frac{291}{3}[/tex] = 97

The answer is D) 97
