Answer:

The 7th term of the sequence is 0.000768

Step-by-step explanation:

As given, the sequence is : 12, -2.4 , 0.48, ....

The first term = 12

Second term = -2.4

Third term = 0.48

Common ratio = [tex]\frac{-2.4}{12} = \frac{0.48}{-2.4} = -0.2[/tex]

Fourth term = 0.48(-0.2) = -0.096

Fifth term = -0.096(-0.2) = 0.0192

Sixth term = 0.0192(-0.2) = -0.00384

Seventh term = -0.00384(-0.2) = 0.000768

Answer:

66 in approx

Step-by-step explanation:

Given data

Radius= 10.5 inches

The circumference is given as

C= 2πr

Substitute

C=2*3.142*10.5

C=65.982

Hence the Circumference is 66 in approx

Answer:

Yes

Step-by-step explanation:

Length of the third side

[tex]180-(72+78)=30\ \text{ft}[/tex]

The hypotenuse is always the longest side of a right triangle.

So, the hypotenuse here is [tex]c=78\ \text{ft}[/tex]

[tex]a=72\ \text{ft},b=30\ \text{ft}[/tex]

[tex]c=\sqrt{a^2+b^2}\\\Rightarrow c=\sqrt{72^2+30^2}\\\Rightarrow c=\sqrt{6084}\\\Rightarrow c=78\ \text{ft}[/tex]

The Pythagoras theorem applies so the fence does form a right triangle.

Answer:

3.9 that's how much he had

Answer:

He had $3.90 at the start of his walk.

Step-by-step explanation:

To find out how much money he had before his walk, you would take 2.55 + 1.35 and that you give you 3.9. But since we are dealing with money, you need to have the 0 at the end. So he started with $3.90 when he started his walk.

Answer:

the answer is a = -4

Step-by-step explanation:

pls mark brainliest

Answer:

a = -4

Step-by-step explanation:

To find a, we need to get the variable on one side of the equation. So first we distribute.

-3a+5=a-6a-3 Now we subtract 5 from both sides and add the a to the -6a

-3a=-5a-8 Now we add 5a to both sides

2a=-8 And lastly divide both sides by 2

a= - 4

I hope this helps and please add me as brainliest! Thanks! <3

Answer:

19/25 it cant simplified

Step-by-step explanation:

Answer:

12/13 or 92.31%

Step-by-step explanation:

Answer:

48%

Step-by-step explanation:

So, we have to find what percentage is 12 out of the whole thing so:

We add the boys and the girls together to get the whole thing:

12 + 13 = 25

Then we turn it into a fraction:

12/25 = 48/100

So, 48% of the class is boys

Answer:

d. 60

Step-by-step explanation:

x=15/0.25

15/0.25=60

Answer:

9060

Step-by-step explanation:

let s be the amount of sugar the bakery ordered in the last order

s - 0.25s = 6795

0.75s = 6795

divide both sides by 0.75

9060

Answer:

2x + 3y = 6

Step-by-step explanation:

2x + 3y = 6

-2x. -2x

3y/3 = -2x + 6/3

Y = -2/3x + 2

Answer:

i think C is 27 1/2 and D is 2 1/22 i dont know though let me know if its wrong

Step-by-step explanation:

i just turned them into mixed numbers

Answer:

5/7.

Step-by-step explanation:

Convert to slope-intercept form:

5x – 7y = 9

Subtract 5x from both sides:

-7y = -5x + 9

Divide through by -7:

y = (-5/-7) x + -9/7

y = 5/7 x - 9/7

The slope is 5/7.

Answer:

132= 14

Step-by-step explanation:

The ratio is the division of two quantities in fraction form thus the ratio of the number of boys to the number of adults is 13/2.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given data,

130 boys, 100, girls, and 20 adults.

The ratio of boys to adults = number of boys/number of adults

⇒ 130/20 = 13/2

Hence "The ratio is the division of two quantities in fraction form thus the ratio of the number of boys to the number of adults is 13/2".

Step-by-step explanation:

Answer:

yeet

Step-by-step explanation:

x^2 + 9.5^2 = 11^2

x^2 + 90.25 = 121

x^2 = 30.75

x^2 = [tex]\sqrt{30.75}[/tex]

x = 5.54cm

rounded: 5.5cm

answer: D

Answer: No. If two lines have the same slope they are parallel lines (or they are the same line), so they cannot intersect at one point. Because the triangles are congruent, the angles where the lines meet the x-axis are congruent. Because the lines form the same angle with the x-axis, they are parallel.
