6.247 * 10 to the twelfth power in standard form
Answer: 6,247,000,000,000
Step-by-step explanation:
Here we have the number:
6.247x10^12 and we want to write this in standard form.
You can see that we have a 10^12, this means that we need to move the decimal dot 12 places to the right, if there is not a decimal to the right, we add a zero.
6.247x10^12 = 62.47x10^11 = 624.7x10^10 = 6,247x10^9 = 62,470x10^8 and so on.
eventually, the standard form is:
6.247x10^12 = 6,247,000,000,000
So we end with 12 digits after the six.
Find the value of x in each case:
You can set up an equation for the large triangle made up of the smaller ones by knowing that the total interior angles must sum to 180°. We also can know that angle RPN is also 78° by the geometric law of alternate interior angles. Therefore you know that the angles to sum up are 2x, 2x (which comes from x + x), and 78°.
2x + 2x + 78 = 180
4x + 78 = 180
4x = 102
x = 25.5°
*note, there are many ways to solve this
Find the common difference of the sequence shown. 1/6, 1/3, 1/2 , 2
Answer:
1/6
Step-by-step explanation:
sequence should be 1/6,1/3,1/2,2/3
common difference=1/3-1/6=2/6-1/6=1/6
or 1/2-1/3=(3-2)/6=1/6
or c.d.=2/3-1/2=(4-3)/6=1/6

Now let’s practice what you have learned.
Solve the equation.
4y – 4 = 28
Answer:
y=8Step-by-step explanation:
4y-4=28
4y=28+4
4y=32
y=32/4
y=8
now plug in 8 for y and check the equation true:
4y-4=28
4*(8)-4=28
32-4=28
28=28
So, y is equal to eight 8
Answer:
y = 8
Step-by-step explanation:
4y - 4 = 28
take -4 to the equal side, which will change and become +4
so, it will be; 4y = 28 + 4
4y = 32
divide both sides by the number next to the unknown(y), which is 4
y = 8
resolve the following into factor ab+ac-ad
Answer:
a(b+c-d)
Step-by-step explanation:
Each term has a factor of "a", so that can be factored out. The remaining factor cannot be factored any further.
ab +ac -ad = a(b +c -d)
Answer:
a(b + c - d)
Step-by-step explanation:
'a' is common to all three terms of the given expression. Thus, the expression in factored form is a(b + c - d).
Consider the function f(x) = x2 + 12x + 11. x-intercepts: 0 = x2 + 12x + 11 0 = (x + 1)(x+ 11) y-intercept: f(0) = (0)2 + 12(0) + 11 What are the intercepts of the function? The x-intercepts are . The y-intercept is
Answer:
The coordinates of the x-intercepts are;
(-1, 0) and (-11, 0)
The coordinate of the y-intercept is;
(0, 11)
Step-by-step explanation:
The given function is f(x) = x² + 12·x + 11
The x-intercept is at f(x) = 0 which gives;
0 = x² + 12·x + 11 which has been factored as (x + 1)(x+11) such that we have;
(x + 1)(x+11) = 0
x = -1, or x = -11
The y-intercept occurs at x = 0, we therefore have;
f(0) = (0)² + 12·(0) + 11 = 11
Therefore, we have f(0) = 11 = Y
Given that at the x-intercept, y = 0, then the coordinates of the x-intercepts are;
(-1, 0) and (-11, 0)
Given that at the y-intercept, x = 0, then the coordinate of the y-intercept is;
(0, 11).

Bill wants to be a marine biologist when he grows up. His entire room is ocean-themed, so he is painting his bed frame blue to match. He estimates that he will need 5 cups of paint, but the hardware store only sells paint in quarts. If Bill buys 2 quarts of paint, how many cups will he have left?
Answer:
3 cups
Step-by-step explanation:
Bill needs 5 cups of paint for his bed frame.
The store only sells in quarts and so he buys 2 quarts of paint.
Let us convert to cups to see how many he bought:
1 quart = 4 cups
2 quarts = 2 * 4 = 8 cups
Bill bought 8 cups of paint. Therefore, the number of cups he has left is:
8 - 5 = 3 cups
He will have 3 cups left.

Which equation can be used to solve for c?
c = (5)cos(35o)
c = StartFraction 5 Over cosine (35 degrees) EndFraction
c = (5)sin(35o)
c = StartFraction 5 Over sine (35 degrees) EndFraction
Answer:
c = 5 / cos 35Step-by-step explanation:
To find c we use cosine
cos ∅ = adjacent / hypotenuse
c is the hypotenuse
BC is the adjacent
cos 35° = 5 / c
c = 5 / cos 35Hope this helps you

58. 122. 61. None of the choices are correct
Answer:
C. 61
Step-by-step explanation:
Two sides are equal, so the triangle is an isosceles triangle.
Both base angles are equal.
Angles in a triangle add up to 180 degrees.
58 + x + x = 180
58 + 2x = 180
2x = 122
x = 61

3cm
R
4cm
O 16
28
26
65
Answer:
No, it is not possible to construct a triangle with lengths of its sides as 4 cm, 3 cm and 7 cm because here we see that sum of the lengths of two sides is equal to third side i.e., 4+3 = 7. As we know that, the sum of any two sides of a triangle is greater than its third side, so given statement is not correct.
Step-by-step explanation:
What is the value of Y?
Answer: 57 = y
Step-by-step explanation: To find the value of y in this problem, we use the exterior angle theorem which states that the measure of the exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
So in the diagram shown, the exterior angle, 114,
is equal to the sum of the remote interior angles, y + y.
So we have 114 = y + y.
Solving from here, first combine like terms on the right side.
So we have 114 = 2y.
Now divide both sides by 2 to get 57 = y.

Find the equation of the line through point (−2,−2) and parallel to 3x+4y=12. Use a forward slash (i.e. "/") for fractions (e.g. 1/2.
Answer:
3x + 4y = - 14
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 4y = 12 ( subtract 3x from both sides )
4y = - 3x + 12 ( divide all terms by 4 )
y = - [tex]\frac{3}{4}[/tex] x + 3 ← in slope- intercept form
with slope m = - [tex]\frac{3}{4}[/tex]
Parallel lines have equal slopes, thus
y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation
To find c substitute (- 2, - 2) into the partial equation
- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - [tex]\frac{7}{2}[/tex]
y = - [tex]\frac{3}{4}[/tex] x - [tex]\frac{7}{2}[/tex] ← in slope- intercept form
Multiply through by 4 to clear the fractions
4y = - 3x - 14 ( add 3x to both sides )
3x + 4y = - 14 ← in standard form
The shorter leg of a 30°−60°−90° triangle is 4 in. Find the hypotenuse and the other leg. Answer: The length of the hypotenuse is ________ in. The length of the other leg is __________in.
Answer:
The length of the hypotenuse is 8 inches; the length of the longer leg is 4√3 inches.
Step-by-step explanation:
Note that tan 60 degrees = (length of longer leg) / (length of shorter leg), or
tan 60 degrees = (length of longer leg) / 4 in.
Thus, (length of longer leg) = (4 in)(tan 60 degrees)
= (4 in) [√3/1] = 4√3 in
Also, cos 60 degrees = (adjacent side) / (hypotenuse. We want to find the hypotenuse and thus solve this equation for it:
(hypotenuse) = (adjacent side) / (cos 60) = (4 in)( 2/1 ) = 8 in
The length of the hypotenuse is 8 inches; the length of the longer leg is 4√3 inches.

If c+1/d=5 , what is the value of 30d/2c+2
Answer:
3
[tex]d\in R,\hspace{5}d\neq 0[/tex]
Step-by-step explanation:
You can solve for any variable. From the first equation, let's solve for c :
[tex]\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1[/tex]
Now, replace the value of c into the other equation:
[tex]\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\[/tex]
Using distributive property
[tex]\frac{30d}{10d-2+2} =\frac{30d}{10d} =3[/tex]

If the number of bacteria in a colony doubles every 10 hours and there is currently a population of 300 bacteria, what will the population be 20 hours from now?
Answer:
1200 bacteria
Step-by-step explanation:
20 hours divided by 10 hours = 2, so it will be doubled two times.
300 times 2 for the first doubling = 600
600 times 2 for the second doubling = 1200

in the following APs,find the missing terms in the boxes
1). 5_,_,9/2
2).-4,_,_,_,_,6
3)._,38,_,_,_,-22
Answer:
see explanation
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
(1)
Given a₁ = 5 and a₄ = [tex]\frac{9}{2}[/tex] , then
5 + 3d = [tex]\frac{9}{2}[/tex] ( subtract 5 from both sides )
3d = - [tex]\frac{1}{2}[/tex] ( divide both sides by 3 )
d = - [tex]\frac{1}{6}[/tex]
add - [tex]\frac{1}{6}[/tex] to each term
5, [tex]\frac{29}{6}[/tex], [tex]\frac{14}{3}[/tex], [tex]\frac{9}{2}[/tex]
(2)
Given a₁ = - 4 and a₆ = 6, then
- 4 + 5d = 6 ( add 4 to both sides )
5d = 10 ( divide both sides by 5 )
d = 2
Add 2 to each term
- 4, -2, 0, 2, 4, 6
(3)
Given a₂ = 38 and a₆ = - 22, then
a₁ + d = 38 → (1)
a₁ + 5d = - 22 → (2)
Subtract (1) from (2) term by term
4d = - 60 ( divide both sides by 4 )
d = - 15
Substitute d = - 15 into (1)
a₁ - 15 = 38 ( add 15 to both sides )
a₁ = 53
Thus
53, 38, 8, - 7, - 22
