Answer:
d
Step-by-step explanation:
The sum to n terms of a geometric sequence is
[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]
where a is the first term and r the common ratio
Here a = 3 and r = 12 ÷ 3 = 4 , thus
[tex]S_{8}[/tex] = [tex]\frac{3(4^{8}-1) }{4-1}[/tex]

If an angle is bisected to form two new 10 degree angles, what was the measure of the original angle?
Answer:
20 degrees
Step-by-step explanation:
Bisected means to cut or divide in half. After knowing this you should realize that the two new parts of the angle should be equal. They are both ten degrees, so to get the measure of the original angle add both of the sides together.

Solution:
Equation of the parabola that open downwards and is symmetric about y-axis is [tex](x-h)^2=-4p(y-k)[/tex] where [tex](h,k)[/tex] denotes the vertex and focus is at [tex](h,k+p)[/tex]
[tex]g(x)=-(x-.....\,\,\,\,)^2+\left ( ....... \right )\\(x-.....\,\,\,\,)^2=-\left ( g(x)-(....) \right )[/tex]
[tex](x-h)^2=-\left ( g(x)-(k) \right )[/tex]
From the graph, vertex is [tex](5,4)[/tex]. Put [tex](h,k)=(5,4)[/tex]
[tex]g(x)=-(x-5)^2+4\\=-\left [ (x-5)^2-2^2 \right ][/tex]
Use formula [tex]a^2-b^2=(a+b)(a-b)[/tex]

[tex]g(x)=-\left [ (x-5)^2-2^2 \right ]\\=-\left [ (x-5-2)(x-5+2) \right ]\\=-(x-7)(x-3)[/tex]
Which linear equation has no solution? 23(9x+6)=6x+4 5x+12=5x−7 4x+7=3x+7 −3(2x−5)=15−6x
Answer:
5x+12=5x-7
Step-by-step explanation:
If both x's on each are the same number, but with different constants, then the equation is unsolvable. If 5x+12=y, then 5x-7 can't also equal y because they are two different equations.
With all other equations, although some come out irrational, they are solvable and have a solution to them.

Jordan prepares 200 name tags to use at a meeting. The number for each color of the name tag is described below.
35%of the name tags are blue
3/8 of the name tags are yellow
*all of the remaining name tags are red
how many of Jordans name tags are red ?
A)55
B)90
C)110
D)145
please help thxs!! due today 11:00 pm
Answer:
The answer would be A. 55.
Step-by-step explanation:
For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.
For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.
The number of Jordan's tags that are red are; A: 55 tags
How to calculate proportions?35% of the 200 tags are blue. Thus;
Number of blue tags = 35% * 200 = 70 tags
3/8 of the 200 name tags are yellow. Thus;
Number of yellow tags = 3/8 * 200 = 75 tags
The remaining tags are red. Thus;
Number of red tags = 200 - (75 + 70)
Number of red tags = 55 tags

A car travels 60 miles due north then makes a turn due west. It travels 72 miles west. How far is the car from its starting point? Round to the nearest tenth.
Answer:
93.7 miles
Step-by-step explanation:
This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.
We need to find the hypotenuse. We can use Pythagoras rule:
[tex]hyp^2 = opp^2 + adj^2[/tex]
where opp = opposite side to the angle considered
adj = adjacent side to the angle considered
This implies that:
[tex]x^2 = 60^2 + 72^2\\\\x^2 = 8784\\\\x = \sqrt{8784} \\\\x = 93.7 miles[/tex]
The car is 93.7 miles far from its starting point.
Use the elimination method to solve the system of equations. Choose the
correct ordered pair.
7x+4y= 39
2x + 4y = 14
A. (3,2)
B. (5,1)
C. (5,4)
D. (3,4)
Answer:
The answer is B.
Step-by-step explanation:
When Elimination method is applied, you have to eliminate one of the variables from both equations. Firstly, both equations contain 4y so you can subtract it :
[tex]7x + 4y = 39 - - - (1)[/tex]
[tex]2x + 4y = 14 - - - (2)[/tex]
[tex](1) - (2)[/tex]
[tex]7x + 4y - 2x - 4y = 39 - 14[/tex]
[tex]5x = 25[/tex]
[tex]x = 25 \div 5[/tex]
[tex]x = 5[/tex]
Next, you have to substitute x = 5 to any equations. I will choose to put in (2) :
[tex]substitute \: x = 5 \: into \: (2)[/tex]
[tex]2(5) + 4y = 14[/tex]
[tex]10 + 4y = 14[/tex]
[tex]4y = 14 - 10[/tex]
[tex]4y = 4[/tex]
[tex]y = 4 \div 4[/tex]
[tex]y = 1[/tex]
Therefore, put your answer in coordinate form :
[tex]x = 5 \\ y = 1[/tex]

Answer:
The answer is 324π m².
Step-by-step explanation:
Given that the surface area of sphere formula is S.A = 4×π×r² where r is radius. The diameter of sphere is 18m so you have to divide it by 2 to find it's radius :
[tex]radius = diameter \div 2[/tex]
[tex]radius = 18 \div 2[/tex]
[tex]radius = 9m[/tex]
Then substitute into the formula :
[tex]s.a = 4 \times \pi \times {r}^{2} [/tex]
[tex]let \: r = 9[/tex]
[tex]s.a = 4 \times \pi \times {9}^{2} [/tex]
[tex]s.a = 4 \times \pi \times 81[/tex]
[tex]s.a = 324\pi {m}^{2} [/tex]
Answer:
The answer is 324π m².
Step-by-step explanation:
Given that the surface area of sphere formula is S.A = 4×π×r² where r is radius. The diameter of sphere is 18m so you have to divide it by 2 to find it's radius

Sarah can eat 45 blueberries in 2 minutes. If she eats blueberries for 45 minutes straight, how many did she eat?
Answer:
1012
Step-by-step explanation:
She eats 1012 because:
If she eats 45 in 2 minutes then she eats 22.5 in 1 minute.
This is because 45 ÷ 2 = 22.5
Sarah eats blueberries for 45 minutes so we multiply 22.5 by 45
22.5 × 45 = 1012.5
She ate 1012 full berries.

The lengths of the sides of a triangle are consecutive odd numbers. What is the length of the longest side if the perimeter is 45?
Answer:
17
Step-by-step explanation:
Let x be the first side
x+2 is the next side ( consecutive odd number)
x+4 is the third side ( consecutive odd number)
P = x + x+2 + x+4
45 = x + x+2 + x+4
Combine like terms
45 = 3x+6
Subtract 6 from each side
45-6 = 3x+6-6
39 = 3x
Divide by 3
39/3 = 3x/3
13 =x
The longest side is
x+4
13+4 = 17
The longest side is 17
The longest side is 16.
Let the consecutive sides be y, y+1, and y+2.
The perimeter of a triangle is gotten by adding all its sides. Therefore, the perimeter will be:
y + y+1 + y+2 = 45
Collect like terms
3y = 45 - 3
3y = 42
Divide both side by 3
3y/3 = 42/3
y = 14
Therefore, the longest side will be:
y + 2 = 14 + 2 = 16
The longest side is 16.

What is the sum of the interior angles in the polygon below? Show and explain your work.
Answer:
HEXAGON:
Using the same methods as for hexagons to the right (I'll let you do the pictures)...
To find the sum of the interior angles of a dodecagon, divide it up into triangles... There are ten triangles... Because the sum of the angles of each triangle is 180 degrees... We get
So, the sum of the interior angles of a dodecagon is 1800 degrees.
Regular Dodecagons:The properties of regular dodecagons:
All sides are the same length (congruent) and all interior angles are the same size (congruent).
To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above)... And there are twelve angles...
So, the measure of the interior angle of a regular dodecagon is 150 degrees.
The measure of the central angles of a regular dodecagon:
To find the measure of the central angle of a regular dodecagon, make a circle in the middle (I'll let you do the picture)... A circle is 360 degrees around... Divide that by twelve angles...
So, the measure of the central angle of a regular dodecagon is 30 degrees.

from least to greatest:
6/5, 0.3815, 97%
Answer:
6/5, 0.3815, 97%
Step-by-step explanation:
6/5 = 1.2 = 12%
0.3815 * 100 = 38.15%
97%
Answer:
.3815, 97%, 6/5
Step-by-step explanation:
To keep this simple, just convert all of them into decimals. 6/5= 1.2 if you divide it. 97%= 0.97 because you divide the percent by 100 to get to the decimal. And finally, .3815 is already a decimal.
Now, you just sort it out. 1.2 is the largest number because it is the only one that is greater than 1. So that would go last
Now you compare .97 and .3815. To find out which one is greater, look in the tenths place, or the first digit after the decimal. 9 is obviously greater than 3 so .97 is greater than .3815.
Using this info we found, the smallest is .3815, then 97%, then 6/5

which choice is equivalent to the quotient below?
Answer:
A.) 3
Step-by-step explanation:
Let's start with the numerator:
√36/√4
√36 = ?
We know that 36 is a perfect square, or the product of one number multiplied by itself.
6 x 6 = 36
So, √36 = 6
Let's look at the denominator:
√36/√4
√4 = ?
We know that 4 is also a perfect square.
2 x 2 = 4
So, √4 = 2
Now we have the numerator: 6
And the denominator: 2
Fraction: 6/2
If we simplify this fraction, we are left with 3 because 6 divided by 2 is 3.
