Answer:

x = 36 degrees

Step-by-step explanation:

Every Triangle adds up to 180 degrees so in order to solve this we must add together the two angle we know which is

97 + 47 = 144

Then we take this number and we subtract is from 180 to find the third angle

180 - 144 = 36

Answer:

t = 5 seconds h = 128 feet

Step-by-step explanation:

The given equation of the object is :

[tex]h(t)=-16t^2+64t+80[/tex] .....1

When it hits the ground,

h(t) = 0

So,

[tex]-16t^2+64t+80=0\\\\t=-1\ s\ and\ t=5\ s[/tex]

The object will hit the ground in 5 seconds.

Now, put t = 1 s in equation (1).

[tex]h(1)=-16(1)^2+64(1)+80\\\\h(t)=128\ ft[/tex]

The object is at a height of 128 ft at 1 second.

Answer:

The first step is to determine the largest number that evenly divides the numerator and the denominator (also called the Greatest Common Factor of these numbers). In other words, what's the biggest number that goes into '2' (the numerator) and '4', the denominator?

Step 2. Once you've answered step 1 and realized that, for our fraction at least, the greatest number that evenly divides 2 and 4 is '2'. Now divide the top and the bottom by 2 to get your simplified fraction which is ½.

I hope this helps if you have any questions on my answer plz let me know Ty :3

Answer:

find the greatest common factor, then divide the bottom and the top, and you have that as your answer

hope this helps

Required

Select all true statements

First, calculate the total observed frequency;

[tex]Total = 11 + 16 + 14 + 20 + 12 + 17[/tex]

[tex]Total = 90[/tex]

(a): Relative frequency of 4 is 2/9

Relative frequency is calculated by:

[tex]RF= \frac{Observed\ Frequency}{Total}[/tex]

For roll 4

[tex]Observed\ frequency = 20[/tex]

So, the relative frequency is:

[tex]RF = \frac{20}{90}[/tex]

Simplify

[tex]RF = \frac{2}{9}[/tex]

(a) is true

(b): Experimental probability of 3 greater than its theoretical probability

The experimental probability is its relative frequency;

For roll 3

[tex]Observed\ frequency = 14[/tex]

The experimental probability is:

[tex]Pr = \frac{14}{90}[/tex]

Simplify

[tex]Pr = \frac{7}{45} = 0.156[/tex]

To calculate  the theoretical probability, w have:

[tex]S = \{1,2,3,4,5,6\}[/tex] ---- sample space

[tex]n(S)= 6[/tex]

[tex]n(3) = 1[/tex] --- number of times 3 occur

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The theoretical probability is [tex]greater\ than\ the[/tex] experimental probability.

(b) is false

(c): Experimental probability of 2 greater than its theoretical probability

Using the explanations in (b), we have:

For roll 2

[tex]Observed\ frequency = 16[/tex]

The experimental probability is:

[tex]Pr = \frac{16}{90}[/tex]

Simplify

[tex]Pr = \frac{8}{45} = 0.178[/tex]

To calculate the theoretical probability, we have:

[tex]n(S)= 6[/tex]

[tex]n(2) = 1[/tex]

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The experimental probability is [tex]greater\ than\ the[/tex] theoretical probability.

(c) is true

(d): Relative frequency of 5 is 2/13

For roll 5

[tex]Observed\ frequency = 12[/tex]

The relative frequency is:

[tex]RF = \frac{12}{90}[/tex]

Simplify

[tex]RF = \frac{2}{15}[/tex]

(d) is true

Step-by-step explanation:

Answer is A and D Because i got their answer wrong

Answer:

The answer is (13,48,50)

Part B: 65

Part A: Since there are 30 students of the class and 17 are boys, there are 13 girls. 13/30 = 43.33 = 43%.

Part B: Since 43% of the class are girls, we do 150*0.43 for the whole 7th grade which is 64.5 which I rounded to 65.

Step-by-step explanation:

here's your solution

==> by using Pythagoras theorem

==> base^2 = hypotenuse^2 - perpendicular^2

==> hypotenuse = 18 , perpendicular = 16

==> base^2 = 18^2 - 16^2

==> base^2 = 324 - 256

==> base^2 = 68

==> base = √68

==> base = 8.24

Answer:

i think you would multiply it all together , sorry if im wrong :(

Answer:

OC. log,8

Step-by-step explanation:

5 log,2 -log,4, = 0.903089987

log,8, = same as above

The expression  [tex]5log2-log4[/tex] is equivalent to  [tex]log8[/tex]  which is option c.

A logarithm answers the question "How many of this number do we multiply to get that number?" Example How many 2s must we multiply to get 8 that is 3.

Given,

[tex]5log2-log4[/tex]

= [tex]log2^5-log4[/tex]

= [tex]log32-log4[/tex]

= [tex]log\frac{32}{4}[/tex]

= [tex]log8[/tex]

Hence, the expression  [tex]5log2-log4[/tex] is equivalent to  [tex]log8[/tex] .

Answer:

$1.26

Step-by-step explanation:

So you just have to find 2.25% of 56.

To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:

2.25% of 56

Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:

2.25% × 56

Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.

2.25% = 0.0225

And now you have:

0.0225 × 56

Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.

But once you multiply 0.0225 × 56, you get an answer: 1.26

Answer:5 I think

Step-by-step explanation:

75-35=40 40 divided by 8 is 5

Answer:

The answer is 5=x (he is able to buy 5 videogames)

Step-by-step explanation:

First, you need to put this into an equation format with a variable (x) for the videogames. Here is what the equation should look like: 75 = 35 + 8x

75 being the total amount of money he has to spend, 35 being what he had to spend or knows he will spend on the controller, and the 8 is for each videogame. We put an 'x' behind the 8 to signal that we don't know how many games he can buy. So, then we need to solve the equation.

75=35+8x

-35 on both sides

So, 40=8x, then you divide by 8 to get x by itself

5=x

The 'x' in this equation is how many videogames he is able to buy. The way you could check your work is if you plugged 5 back into x. What I mean is this: 35+8(5) needs to equal 75, and it does, so you're good!
