Answer:

  4^7

Step-by-step explanation:

You know that an exponent signifies repeated multiplication. The value of the exponent is the number of times the base appears as a factor.

You also know that identical factors in the numerator and denominator of a fraction cancel.

The given fraction has 9 factors of 4 in the numerator, and 2 factors of 4 in the denominator. The two in the denominator cancel an equal number in the numerator, leaving a value that has 7 factors of 4:

What is 8/9 + 1/6 as a fraction

Answers

Answer:

[tex]\frac{19}{18}[/tex]   or   [tex]1 \frac{1}{18}[/tex]

Step-by-step explanation:

First, both fractions need to have a common denominator.

The LCM of 9 and 6 is 18.

[tex]\frac{16}{18} +\frac{3}{18}[/tex]

Add the numerators.

You get: [tex]\frac{19}{18}[/tex]

The mixed number form is [tex]1 \frac{1}{18}[/tex]

The expression  [tex]\frac{8}{9} +\frac{1}{6},[/tex] expressed as a fraction, is [tex]\frac{19}{18}.[/tex]

In order to add fractions, it is essential to determine a common denominator.

The common denominator is [tex]9 \times 6 = 54.[/tex]

Now, let's convert the fractions to have the common denominator:

When we multiply the fraction 8/9 with 6 in numerator and denominator we get 48/54.

[tex]\frac{8}{9}= \frac{8}{9} \times \frac {6}{6}[/tex]

[tex]= \frac{48}{54}[/tex]

Now multiply the fraction 1/6 with 9 in numerator and denominator to make 54 in denominator:

[tex]\frac{1}{6}= \frac{1}{6} \times \frac {9}{9}[/tex]

[tex]= \frac{9}{54}[/tex]

Now, we can add the fractions:

[tex]\frac{48}{54} + \frac{9}{54} = \frac{(48 + 9)}{54}[/tex]

[tex]=\frac{57}{54}[/tex]

Despite this, we have the option to simplify the fraction by dividing both the numerator and the denominator with their greatest common divisor, which is 3.

[tex]\frac{57}{54} = \frac{19}{18}[/tex]

Therefore, [tex]\frac{8}{9} +\frac{1}{6},[/tex] expressed as a fraction, is [tex]\frac{19}{18}.[/tex]

A student answered 38 problems on a test correctly and received a grade 95%. How many problems were on the test, if all the problems were worth the same number of points? (Round to the nearest whole number)

Answers

Answer:

36 questions

Step-by-step explanation:

the question can be rewritten to be:

what number out of 38 is equal to 95 percent

now you can use this ratio:

is/of = percent/100

x/38 = 95/100

cross-multiply to get:

100x = 38(95)

100x = 3610

x = 36.1

An experiment consists of dealing 7 cards from a standard​ 52-card deck. What is the probability of being dealt exactly 4 face cards​?

Answers

Answer:

The probability that the first card is a heart is 13/52

For the second card it is 12/51 (There are only 51 cards and only 12 of them are in the heart suit.)

For the third card it is 11/50

4th card 10/49

5th card 9/48

6th card 8/47

7th card 7/46

 

The total probability of all of these events occurring is the product of each individual probability.

 

So, the answer is (13 * 12 * 11 * 10 * 9 * 8 * 7) / (52 * 51 * 50 * 49 * 48 * 47 * 46)

 

which equals exactly 33 / 2,572,780 or roughly 1 chance in about 77,963

an airplane can travel 550 mph in still air. if it travels 3498 miles with the wind in the same length of time it travels 3102 miles against the wind, what is the speed of the wind?

Answers

Answer:

The 20 mph headwind slows the plane down. This is because the headwind comes at the head of the plane and goes in the opposite direction of the plane.

So the plane's actual speed (with the wind included) is 550-20 = 530 mph.

Original domain and range:
D: [-1,1] R: [0,1]
What is the domain and range of
y= f(x+2)+1

Answers

Step-by-step explanation:

if I understand correctly, then f(x) has the domain of [-1, 1] and the range of [0, 1].

the domain of a function is the interval or set of the valid values of x. and the range is the interval or set of the valid values of y.

the new function we could call g(x) is

y = f(x+2) + 1

so, remember, f(x) is only defined for x values of of [-1, 1].

the argument of f(x) must never be outside that interval, or it is undefined.

the new function now uses f(x) in the form of f(x+2). that means, if we use the same x values as for the original f(x) we would land mostly in undefined areas (only x=-1 would work), because we would use f(x) with argument values from 1 to 3.

how can we regulate this back to the valid interval of -1 to 1 ?

by saying that the domain of g(x) is actually 2 less than the domain of f(x) : [-3, -1]

the "+ 1" at the end changes the range. g(x) has then a range interval that is greater by 1 than the range interval of basic f(x).

so, it is [1, 2]

Answers

Answer:

Step-by-step explanation:

Answer all for brainliest asap pls

Answers


1.

Since ABCD is a rectangle, then

angleABE = 90 degrees

angle ABE + angle BEA + 41 = 180

Substitute the known and solve for angle BEA

angle BEA + 41 = 90

angle BEA = 49 degrees

But,

x + angleBEA + 61 = 180 (angles in a straight line)

x = 180 - 61 - 49

x = 70 degrees

2.

triangle XYZ is equilateral, meaning all angles in it are the same, each 60 degrees.

Therefore,

Angle YZX = 60

But Angle YZX = x + 32 (exterior angles equal to the sum of the two opposite interior angles)

60 = x + 32

Therefore,

x = 28 degrees

3.

Angle QPR = Angle QRP (equal oppo sides, equal opposite angles)

Therefore, 2angleQRP + 64 = 180 (angle sum of a triangle)

Angle QRP = 58 degrees

But angle QRP = x + 35 (exterior angles equal to the sum of the two opposite interior angles)

58 = x + 35

x = 23 degrees

Answer:

See below:

Step-by-step explanation:

For the first one, we know <ABC is 90 degrees due to it being a rectangle.

Since we know that, the angles in that triangle are 41 degrees 90 degrees and y degrees (y is <AEB) in this case.

We know that the sum of angles in a triangle are 180 degrees therefore:

If we solve that, we get that y is 49 degrees.

Now to get x, we know its a supplementary angle, therefore 61 degrees + 49 degrees + x = 180 degrees.

We now know that x is 70 degrees

For the second one, since its an equilateral triangle, we know that all angles inside of it are 60 degrees.

What we can do is first find what <XZW is by subtracting 60 from 180 due to the supplementary angles theorum.

Therefore <XZW is 120 degrees.

Now, all angles inside a triangle are always 180 degrees so therefore:

[tex]x=180-(120+32)\\x=28[/tex]

For the final one, we know that <QRP is equal to 64 degrees due to the bottom two triangles of an isoceles triangle being equal.

On that, we get 23 degrees for the last one due to supplementary angles + 180 deg in triangle.
