Answer:
CPU
Explanation:
The CPU is like the brain of the computer, while the motherboard is like the spine. The CPU carries out the instructions. The RAM is like the short-term memory, so you can carry out tasks quicker. The keyboard - well, the keyboard simply types out the command but does not carry it out.
Answer: Hot dog = $3.50
Drink = $2.0
Step-by-step explanation:
Let the cost of a hot dog be x
Let the cost of a drink be y.
From the question above, we can form an equation as:
3x + 4y = 18.50 ....... i
4x + 2y = 18 ......... ii
Multiply equation i by 4
Multiply equation ii by 3
12x + 16y = 74 ...... iv
12x + 6y = 54 ...... v
Subtract v from iv
10y = 20
y = 20/10
y = 2
A drink cost $2
From equation ii
4x + 2y = 18
Recall that y = 2
4x + 2(2) = 18
4x + 4 = 18
4x = 18 - 4
4x = 14
x = 14/4
x = 3.5
A hot dog ost $3.50
There are special trigonometric angle ratios for right triangles, which are sine (sin), cosine (cos), and tangent (tan). Sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, and tangent is opposite over adjacent.
You can remember this with SOHCAHTOA. S=sin, O=opposite, H=hypotenuse
The angle is given along with its adjacent side (1.2) and the hypotenuse (x). Use cosine.
Cos(33) = adjacent/hypotenuse
Cos(33) = 1.2/x
x = 1.2 / cos(33)
Now type into your calculator 1.2 / cos33
It would depend on if the triangle was regular or irregular.So no if the triangle has different angles.If that is so then...
False.
Step-by-step explanation:
Before we answer, the area of a Circle given it radius is
The area of a circle given it diameter is
So let answers question 1-4.
1. The area is
2. The area is
3.
4.
For the 5th problem, circumference is
where d is the diameter and
where r is the radius.
A circumference of 100 m means the radius is 50 because
So this means the area is
