I need help with this question

Answer:

Step-by-step explanation:

you are given the law of sines, in the question, so i'm guessing you don't get "law of sines" ???  

some times I think people might just be lazy and they don't try, but I can understand if you really don't get "law of sines' b/c it is kinda abstract.

Any way here is how you solve this problem and please ask if you don't understand about something I do to solve this.   Ask about it if you don't get it.  :)

Sin(45) / c   = Sin(45) / 3  

now algebraically solve for c

3* Sin(45) / Sin(45)  = c

if you're thinking the answer is 3 you're right.

indecently , if you didn't notice, this is an isosceles triangle and they do have the same length legs.   so  you know that x = 3 right away from that, but, it's good to understand Law of Sines as well.  :)  

Answer:

Maria's homework time is now 9 hours 12 minutes.

Step-by-step explanation:

Since Maria decides to increase her homework time by 15%.

Then,

15% of 8 hours = [tex]\frac{15}{100}[/tex] x 8 hours

                        = 0.15 x 8 hours

                        = 1.2 hours

(Note that: 1.2 hours = 1 hour 12 minutes)

15% of 8 hours = 1 hour 12 minutes

her new homework time = 8 hours + 1 hour 12 minutes

                              = 9 hours 12 minutes

Maria's homework time is now 9 hours 12 minutes.

Answer:

either $180 or $90?

Step-by-step explanation:

first i think you divide 90 by 2, which gives you 45. multiply 45 by 3, which is 135, then multiply 45 by 1, which is just 45. add those together and you get 180. i'm not too sure what you're looking for in the question, but if you're looking for the difference between what he bought them for, it'd be $90. if youre looking for how much he got from those apples, it's $180. hope that helps :)

By applying Pythagorean's theorem, the hypotenuse of this triangle is equal to: D. √32 inches..

Given the following data:

Adjacent side = 4 inches

Opposite side = 4 inches.

In order to calculate the hypotenuse of this triangle, we would apply Pythagorean theorem.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

Substituting the given parameters into the formula, we have;

c² = 4² + 4²

c² = 16 + 16

c² = 32

c = √32 inches.

Answer: 49

Step-by-step explanation:

The missing constant term in the perfect square is 49.

x^2 + 14x + 49

We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.

Answer:

(a) At 1.5 seconds, the ball is 15ft high

Step-by-step explanation:

Given

[tex]Fence:= 20ft[/tex]

[tex]h(t) := -16t^2 + 30t + 6[/tex]

Required

Select the true statement

See attachment for options

Option (a): At 1.5 seconds, the ball is 15ft high

This implies that:

[tex]t = 1.5[/tex]

Substitute [tex]t = 1.5[/tex] in [tex]h(t) := -16t^2 + 30t + 6[/tex]

[tex]h(1.5) = -16 * 1.5^2 + 30 * 1.5 + 6[/tex]

[tex]h(1.5) = -16 * 2.25 + 45 + 6[/tex]

[tex]h(1.5) = -36 + 45 + 6[/tex]

[tex]h(1.5) = 15[/tex]

This statement is true.

Because: [tex]h(1.5) = 15[/tex] means that:

At 1.5 seconds, the ball is 15ft high

Other options will not be checked because only one option can be correct

Answer:

3(8+17)

Step-by-step explanation:

Since the gas prices are the same, we need to find a number that divides into both 24 and 51.

The factors of 24 are 1,2,3,4,6,8,12,24.

The factors of 51 are 1,3,17,51.

So, their common factor is 3. Price of gallon of gas = $3

Now we know the price, we can divide each total by 3 to find out how many each person bought.

One person bought $24 of gas: 24/3 = 8: They bought 8 gallons of gas

Another person bought $51 of gas: 51/3=17: They bought 17 gallons of gas

Represented as an expression, this is:

3(8+17)

Answer:

the correct answer to this is 3(8+17)

(10+77-12)+(-672-18+51)

(87-12)+(-690+51)

75+(51-690)

75-639

Answer:

Step-by-step explanation:

finding PR  ( public relations  :D , not that PR  , the PR on this triangle thingy )

use law of cosines, again

c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]

where

c=PR

a= 9

b = 22

C = the angle of Q or    180 =   97+24+Q  so Q = 180-97-24 = 59°

they tried to trick us.. by not giving us the angle C  for the above cosine formula , but we figured out their diabolical plan  :D   yay super hero math

then

PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]

PR = sq rt [ 81 + 484 -203.9550777 ]

( notice that now it is a subtraction sign instead of a plus sign, this time? )

PR = sq rt [361.0449 ]

PR = 19.0011

to the nearest 10th

19.0 :)

The amount of pizza left will be 6 / 35.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that John and his dad decide to order a pizza to eat while they are watching a World Cup Soccer game. John eats 2/5 of the pizza, and his dad eats 3/7 of the pizza.

The amount of pizza left will be calculated as below:-

Pizza left = 1 - ( 2/5) - (3/7)

Pizza left = ( 35 - 14 - 15 ) / 35

Pizza left = 6 / 35

Therefore, the amount of pizza left will be 6 / 35.
