Answer 1

Answer:

3rd option

Step-by-step explanation:

the explicit formula for a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

here a₁ = - 4 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{12}{-4}[/tex] = - 3 , then

[tex]a_{n}[/tex] = - 4 [tex](-3)^{n-1}[/tex]

A cereal box has a rectangular base with an area of 15 square inches. Its
volume is 180 cubic inches.
What is the height of the box?
A. 12 inches
B. 15 inches
C. 18 inches
D. 10 inches

Answers

Answer:

A

Step-by-step explanation:

Volume of a rectangular prism  = l*b *h

Where base area = l*b

Volume = base area * h

Base area * height = Volume

15 * height = 180

     height = 180/15

     height = 12 inches

Given :-

We have given two parallel lines and two lines intersecte each other and act as a transverse Due to the intersection between two parallel and two traverse lines a triangle is formed. The measurements of the given triangle are 60° , 20° and C

To Find :-

We have to find the values of angles A, B and C

Let's Begin :-

Here, we have

1 triangle whose measures are 60° , 20° and C

Therefore,

By using Angle sum property

ASP states that the sum of all angles of triangles are equal to 180°

That,

[tex]\bold{\angle{X + }}{\bold{\angle{Y + }}}{\bold{\angle{Z = 180}}}{\degree}[/tex]

Subsitute the required values,

[tex]\sf{ 60{\degree} + 20{\degree} + C = 180{\degree}}[/tex]

[tex]\sf{ 80{\degree} + C = 180{\degree}}[/tex]

[tex]\sf{ C = 180{\degree} - 80{\degree}}[/tex]

[tex]\sf{ C = 100}{\degree}[/tex]

Thus, The value of C is 180°

Now,

We have to find the measurement of Angles A and B

Here,

Angle B , unknown angle and Angle C lie on a straight line and we know that the angle formed by straight line is 180°Let the unknown angle be x which is equal to 20° ( Alternative interior angles)

Therefore,

[tex]\sf{\angle{B + }}{\sf{\angle{ x + }}}{\sf{\angle{C = 180}}}{\degree}[/tex]

[tex]\sf{\angle{ B + 20{\degree}+ 100{\degree} = 180{\degree}}}[/tex]

[tex]\sf{\angle{ B + 20{\degree} = 180{\degree}- 100{\degree}}}[/tex]

[tex]\sf{\angle{ B = 80{\degree} - 20{\degree}}}[/tex]

[tex]\sf{\angle{ B = 60{\degree}}}[/tex]

Now,

A, B and 100° lie on a straight line and we know that the angle formed by straight line is equal to 180°

Therefore ,

[tex]\sf{\sf{A + }}{\sf{\angle{B + }}}{\sf{ 100{\degree} = 180}}{\degree}[/tex]

[tex]\sf{\angle{ A + 60{\degree} = 180{\degree} - 100{\degree}}}[/tex]

[tex]\sf{\angle{ A = 80{\degree} - 60{\degree}}}[/tex]

[tex]\sf{\angle{ A = 20{\degree}}}[/tex]

Hence, The measure of Angles A, B and C are 20° , 60° and 100° .

A football field measures 300 feet in length. It can also be expressed as approximately 5. 7 times 10 Superscript n miles. If there are 5,280 feet in 1 mile, which is the most reasonable value of n? Negative 3 Negative 2 2 3.

Answers

The most reasonable value of n  n = -2.

We have given that the length of the football field = 300 feet

It can also be expressed as approximately  [tex]5.7\times 10^{n}miles[/tex]

What is the value of one mile in feet?

Also, 1 mile = 5280 feet....(1)

We have to find 1 feet so divide both side of equation (1)by by 5280 we get,

[tex]1feet=\frac{1}{5280}[/tex]

Now, for 300 feet is,

[tex]300feet=\frac{1}{5280}(300)[/tex]

[tex]300 feet=0.056818181=0.057miles[/tex]

In scientific notation we have,

[tex]300 feet=5.7\times 10^{-2}miles[/tex]

Therefore we get  n = -2.

Kabita has two bags. In the first bag there are 5 blue discs and 3 red discs. In the second bag there are 7 blue discs and 4 red discs. Kabita takes at random a disc from the first bag. She then takes at random a disc from the second bag


Work out the probability that kABITA takes 2 red discs

Answers

The probability that Kabita would take 2 red discs from the bags is 3/22.

What is probability?

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

The probability that Kabita would take 2 red discs = (number of red discs in bag 1 / total number of discs in bag 1) x  (number of red discs in bag 2 / total number of discs in bag 2)

(3/8) x (4/11) = 3/22

(q+4)(9q+5)=0 solve for q

Answers

Answer:

q = -4
q = -5/9

Step-by-step explanation:

Hi!

To solve this question, we can use the zero product property.

What is the Zero-Product property?

The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.

We have (q+4)(9q +5) = 0

That means either q + 4 = 0, or 9q + 5 = 0.

Solve:

q + 4 = 0q = -4

9q + 5 = 09q = -5q = -5/9

We can check both cases:

(-4 + 4)(-36 + 5) = 0

0(-31) = 0

0 = 0

(-9/5 + 4)(9(-5/9) + 5) = 0

(2.2)(-5 + 5) = 0

(2.2)0 = 0

0 = 0
