Trigonometry, how would I find the area of this parallelogram?
Answer:
A ≈ 160 cm²
Step-by-step explanation:
the area (A) of a parallelogram given adjacent sides a and b and angle Θ between them is
A = absinΘ
here a = 12 , b = 15 and Θ = 117° , then
A = 12 × 15 × sin117° ≈ 160 cm²( to the nearest cm² )

You are traveling by car to New York City. The map you will use for your journey is below. d) You plan to begin your journey in San Jose and make stops in Denver and Chicago on your way to New York City. Your father says that your journey will be about 3,000 miles. Is this a close estimation of the distance? Explain your reasoning.
Based on the cities you will go through and your starting and finishing points, your father's estimate is a close estimation of the distance.
How far is New York from San Jose?The map is not provided so we will use a general map.
The distance from San Jose to Denver is around 1,301 miles.
The distance from Denver to Chicago is around 1,004 miles.
The distance from Chicago to New York is around 796 miles.
Added together we get:
= 1,301 + 1,004 + 796
= 3,101 miles
This is close to the 3,000 miles your father estimated.

Step-by-step explanation:
x² + 2x - 35:
what multiplies into -35 and adds into 2?
7 and -5
so the top is now (x + 7)(x - 5)
x² + x - 42
what multiplies into -42 and adds into 1?
-6 and 7
so the bottom is now (x + 7)(x - 6)
the 2 lots of (x + 7) cancel and you are left with (x - 5) / (x - 6)
Answer:
[tex]\frac{x-5}{x-6}[/tex]
Step-by-step explanation:
Let's start with the numerator to factor it.
We need two numbers adding up to 2 and multiplying to -35. Easy to see the number are +7 and -5. You can then factor as [tex]x^2+2x-35=(x+7)(x-5)[/tex]
Denominator then. Same story, Two number adding to 1 and multiplying to -42. Numbers are +7 again and -6. Factors as before:
[tex]x^2+x-42=(x+7)(x-6)[/tex].
Now you can simplify
[tex]\frac{x^2+2x-35}{x^2+x-42} = \frac{(x+7)(x-5)}{(x+7)(x-6)}= \frac{x-5}{x-6}[/tex]

Write down one prime number that lies between each of the following pairs of numbers: a) 45 and 55 b) 62 and 72
==============================================
Remember, prime numbers have only 2 factors: 1 & themselves.
For example, 5 is a prime number because it's only divisible by 1 and 5 (itself)
Now, write down some primes.
1) between 45 and 55
- 47
- it's only divisible by 1 and itself, so it IS prime
2) 62 and 72
67, because it is divisible by 1 and itself only.

The cost of the horse given the amount received at the end of 6 months is 600
How to find the value of the horse?let
h = value of the horse6/12 × 1200 + 6h/12 = 400 + h
700 + 6h / 12 = 400 + h
700 - 400 = h - 6h/12
300 = 12h - 6h / 12
300 = 6h/12

Use the right triangular prism to find the total surface area of the prism. Leave label off answer.
Step-by-step explanation:
the total surface area is the sum of the 5 individual areas in the surface :
2 triangle sides (left and right).
1 back rectangle side
1 rectangle floor
1 inclined rectangle front side
to get the length of the baseline (Hypotenuse) of the right-angled triangles on the side. we use Pythagoras
c² = a² + b²
where c is the Hypotenuse (the side opposite of the 90° angle).
c² = 3² + 4² = 9 + 16 = 25
c = 5
so, now, we have everything we need.
the area of a triangle side (since it is right-angled) :
4×3/2 = 6
2 sides, that makes 12
the area of the back side
6×3 = 18
the area of the floor
6×4 = 24
the area of the inclined front side
6×5 = 30
so, the total surface area is
12+18+24+30 = 84

find the HCF of 50and70 by using euclids algorithm
Answer:
10
Step-by-step explanation:
To find,
HCF of 50 & 70 using Euclid's Division Algorithm.
Solution,
HCF(50 & 70) -- 70 = 50 × 1 + 20.
50 = 20 × 2 + 10
20 = 10 × 2 + 0.
Therefore their HCF is 10.
Answer:
10
Step-by-step explanation:
According to Euclid's Algorithm, c = dq + r , 0 ≤ r < d (where r is the remainder)
As 70 > 50, c = 70 and d = 50
Substituting values of c and d:
70 = (50 x 1) + 20
⇒ 50 = (20 x 2) + 10
⇒ 20 = (10 x 2) + 0
Therefore, the HCF is 10

Evaluate each expression.
so that you're coming purpose of each circle and find the radius and diameter below the circle
please help I need It now answer it correctly
Answer:
1.
The radius is given, so the radius is = 10
The radius is doubled to be a diameter, so (10 + 10) = 20 is your diameter
And to solve for circumference, your formula is;
C = 2πr
Where 'r' represents the radius, and 'π'(pi) is 22/7 or 3.14.
Plug in your values:-
C = 2πr
C = 2(3.14) x 10
C = 6.28 x 10
C = 62.8, so your circumference is 62.8.
2.
Your radius is half of your diameter, so,
D/2 = R
D = diameter
R = Radius
49/2 = 24.5 is your radius.
Your diameter is given, so the diameter is 49.
Use the formula we applied for circumference in our other problem;
C = 2πr
C = 2(3.14) x 24.5
C = 6.28 x 24.5
C = 153.86, so 153.86 is your circumference.
