Is square root of 49/5 a rational number?

Answers

Answer 1
It depends on how that’s written mathematically.

If it’s sqrt(49) / 5, then yes, since that’s 7/5 and 7/5 is a fraction of two integers.

If it was sqrt( 49/5 ), where the /5 is inside the square root, then the answer is no.

Given: Circle W W (-4, 6) Radius = 10 Units Which point lies on circle W?

Answers

Jen sus it’s a cool cool idea for you guys lol I love it too lol I just woke

The solution is : Option A is correct; Point Q is outside circle W

What is circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

If the circle is given as having center W, this means  the radius starts from point W and ends at any point on the circumference.

The radius has been given as 5 units, and this also means any measurement from point W to the circumference is either equal to or less than the radius which is 5 units.

Any measurement that is greater than 5 would be outside of the circumference.

we have,

Point Q is 6 units away from point W, therefore point Q is outside the circumference, that is, outside circle W.

and

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

Step-by-step explanation:

a) 239000 times .8 (aka 80%) = 191200

b) 191200/(12 times 30) = 531.11

531.11 times 1.05 (5%) = 557.667

Round to nearest cent: 557.67

c) 191200/(12 times 30) = 531.11

531.11 times 1.06 (6%) = 562.978

find the defference between 5 2/7 and 2 2/4​

Answers

Answer: 39/14

Step-by-step explanation:

Given

5 2/7 - 2 2/4

Convert mixed fraction to improper fraction

5 2/7 = (5 × 7 + 2) / 7 = (35 + 2) / 7 = 37/7

2 2/4 = (2 × 4 + 2) / 4 = (8 + 2) / 4 = 10 / 4 = 5/2

Find the common denominator for 37/7 and 5/2

First 10 multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

First 5 multiples of 7 = 7, 14, 21, 28, 35

Since 14 is the first common multiple in the lists, 14 would be the common denominator of 37/7 and 5/2

Convert to the common denominator

(37 × 2) / (7 × 2) = 74 / 14

(5 × 7) / (2 × 7) = 35 / 14

Simplify by subtraction of numerator

=74/14 - 35/14

=(74 - 35) / 14

A group of friends in Chicago watched a televised bullfight. They ordered 3 pizzas ($15 each), 15 drinks ($1.50 each), and 6 large nachos ($5.80 each). After adding 5% and a 20% tip to the total, what did they pay for the food? (The tip is 20% of the total before the tax is added) around the answer to the nearest while cent

Answers

Answer:

$127.875

Step-by-step explanation:

cost of 3 pizzas= $15*3

cost of 3 pizzas=$45

cost of 15 drinks=$1.50*15

cost of 15 drinks=$22.5

cost of 6 nachos=$5.80*6

cost of 6 nachos=$34.8

Total cost = pizza cost+ drinks+nachos

total cost=$45+$22.5+$34.8

total cost=$102.3

Now ,

Tip cost=$102.3*20%

=$20.46

tex cost=$102.3*5%

=$5.115

Bill which all friends pay=total cost+ tip cost+tex cost

= $102.3+$20.46+$5.115

=$127.875

10. A rectangle has width the same as a side of a square whose perimeter is 20 m. the length
of the rectangle is 9 m. Find the perimeter of this rectangle.

Answers

Answer:

The perimeter of the rectangle is 28m

Step-by-step explanation:

Perimeter of a square = 4 x side length

20 = 4 x side length

side length = 20/4 = 5m

width of rectangle = 5m

length of rectangle = 9m

Perimeter of rectangle = 2(l + w)

= 2(9 + 5)

= 2(14)

= 28m

State if the given binomial is a factor of the given polynomial.

(2x^3+16x^2+22x-40) + (x+4)

Answers

Answer: Yes, (x+4) is a factor of the given polynomial.

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

Explanation:

We can use the remainder theorem here.

Consider any polynomial p(x). The binomial x-k will be a factor of p(x) if and only if p(k) = 0. I'm using the special case of the remainder theorem, where we look for a remainder of 0.

The binomial x+4 is the same as x-(-4). Compare this to x-k to see that k = -4.

Then plug this k value into the p(x) polynomial given

p(x) = 2x^3 + 16x^2 + 22x - 40

p(-4) = 2(-4)^3 + 16(-4)^2 + 22(-4) - 40

p(-4) = 2(-64) + 16(16) + 22(-4) - 40

p(-4) = -128 + 256 - 88 - 40

p(-4) = 0

This shows that dividing p(x) = 2x^3 + 16x^2 + 22x - 40 over x+4 leads to a remainder of 0. Therefore, (x+4) is a factor of p(x).
