How do you write 7.20 × 100 in standard form?
Answer:
720
Step-by-step explanation:
You move the decimal point twice to the right because 100 has two zeros. But if it was 7.20÷100 it would be 0.072 because you move the point to the left.

The focus of a parabola is (-6, -3). The directrix of the parabola is y =4.
What is the equation of the parabola?

well, we know the directrix is at y = 4 and the focus point is down below it at (-6 , -3), meaning is a downward opening vertical parabola, like the one you see in the picture below.
keeping in mind that the vertex is equidistant from the directrix and focus point by a distance "P", that puts this vertex at ( -6 , 1/2 ), and since the parabola is opening downwards, P is negative.

How many positive integers x satisfy the inequality x^2 + x < 100?
Answer:
9 numbers
Step-by-step explanation:
10^2 + 10 = 110. This is also greater than 100.
Highest value of x is 9.
9^2 + 9 = 90.
Not sure if zero counts, but if it does, it'll be 10 numbers instead.
Hope this helps!
There are 9 positive integers x satisfy the inequality x² + x < 100.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the inequality
x² + x < 100.
First take x= 1 then
1² + 1 = 2 < 100
Take x= 2
2² + 2 = 6 <100
Take x= 3
3² + 3 = 12 < 100
Take x = 4
4² + 4 = 20 < 100
Take x= 5
5² + 5 = 30 < 100
Take x =6, 7, 8, 9, 10 and 11
6² + 6<100
7² + 7<100
8² + 8<100
9² + 9 <100
10² + 10 > 100
So, there are 9 possible digits.

hi guys I am from india . can anybody solve this x+2c
PLEASE HELPPP I can’t really understand this
Answer:
24°
Step-by-step explanation:
Let x = one complementary angle
Let y = the other complementary angle
As the sum of two complementary angles is 90°:
x + y = 90
If one angle is 18° more than two times the other angle:
y = 18 + 2x
Rewrite x + y = 90 to make x the subject:
x = 90 - y
Now substitute x = 90 - y into y = 18 + 2x and solve for y:
y = 18 + 2(90 - y)
⇒ y = 18 + 180 - 2y
⇒ 3y = 198
⇒ y = 198 ÷ 3 = 66
Now substitute found value of y = 66 into x + y = 90 and solve for x:
x + 66 = 90
⇒ x = 90 - 66 = 24
Therefore, the larger angle = 66° and the smaller angle = 24°
Artaud noticed that if he takes the opposite of his age and adds 39 he gets the number 24. How old is Artaud?
Answer:
15
Step-by-step explanation:
Let 'a' represent Artaud's age. He notices the relationship ...
-a +39 = 24
If we add a-24 to both sides, we get ...
15 = a
Artaud is 15 years old.
Answer: 15 years old
Step-by-step explanation:
Let x be Artaud's age. Let the opposite of his age be -x
-x + 39 = 24
-x = 24-39
-x = -15 (multiply both sides by -1)
x = 15 years old
Andre has a dog pen in the shape of a rectangle.
The perimeter of his dog pen is 60 feet.
The length of his dog pen is twice its width.
What is the area of Andre’s dog pen?
Answer:
So for number 1 and 2
Step-by-step explanation:
Perimeter is = 2(L+W)
L=2w as it said on the problem above.
60=2 (2w+w)
60= 2 (3w)
60 = 6w
w= 10 , L=20 P=60
Area of rectangle = L x W
20 x 10 = 200

Product of polynomials can be done by distribution of multiplication over addition. The product of [tex](2x - 3)(2x^2 + 7x - 1)[/tex] is [tex]4x^3 + 8x^2 -23x + 3[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is
[tex](2x - 3)(2x^2 + 7x - 1) = 2x(2x^2 + 7x - 1) -3(2x^2 + 7x - 1) \\(2x - 3)(2x^2 + 7x - 1) = 4x^{1+2} + 14x^2 -2x - 6x^2 - 21x + 3\\(2x - 3)(2x^2 + 7x - 1) = 4x^3 + (14 -6)x^2 + (-2 -21)x + 3\\(2x - 3)(2x^2 + 7x - 1) = 4x^3 + 8x^2 -23x + 3[/tex]
It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]
Also, we've
[tex](-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve[/tex]
where -ve, +ve are sign of operands and result.
That's why [tex]2 \times -1 = -2[/tex]

Step-by-step explanation:
Diane left a 15% tip for a meal costing $44. What was the amount of the tip? $2. 93 $3. 41 $5. 90 $6. 60.
The amount left by Diana is percent part of total food cost. The 15% tip of $44 total cost given by Diana is : Option D: $6.60
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Since the total food cost was $44 and the tip was 15% of the total cost, thus,
[tex]\text{Tip amount} = \dfrac{44}{100} \times 15 = 6.6 \text{\:dollars}[/tex]
Thus,
The 15% tip of $44 total cost given by Diana is : Option D: $6.60

Line q passes through points (9,10) and (5,1), Line r is parallel to line q, What is the slope.
Answer:
slope = 9/4
Step-by-step explanation:
Slope is a ratio (looks like a fraction) It tells you the steepness or flatness of a line.
To find slope you subtract the y's (that's the second number in the ordered pairs; here it's 10 and 1) put that on top. Then subtract the x's and put that on the bottom (here 9 and 5)
Slope = 10-1 / 9-5
=9/4
Now, parallel lines have the same slope, so if one of the lines has slope 9/4, then the other line does too!

Answer:
I believe the answer is B. 15/5 = n/12
Step-by-step explanation:
Once again same method as I've explained before. However, this one tricked me a little bit and still is because of the appearance of the smaller triangle. However, If I don't focus on that I believe this answer is correct. This is because in order to find the missing side we need to find the factor of which the triangle was expanded. So we must divide a given side of the bigger triangle by the same similar side of the little triangle, like 15/5. Then we must divide n by its similar side which the appearance made me think 13 which is not an option so I believe it is 12 and it was just trying to throw me off. So n/12. Therefore that is why I believe B is correct.
