Step-by-step explanation:
area of rec= length×width
=10×4
= 40
radius= diameter/2
=4/2 = 2
area of semicircle= πr²/2
=22/7×2×2×1/2
=6.28
=6.3
adding both
we get,
=40+6.3
= 46.3

9514 1404 393
Answer:
∠G = 18°
Step-by-step explanation:
Complementary angles total 90°. The measure of G is ...
∠G = 90° -72° = 18°
helllpp again lol. but frl it’s angles .
Answer:
x = 41 degrees
Step-by-step explanation:
The total of a triangle is 180 degrees.
Therefore, doing 180 - 104 - 35 will give you the unknown angle.
180 - 104 - 35 = 41 degrees

Solve for x. 6/x+ 2/5 = 8
Answer:
15/19
Step-by-step explanation:
6/x +2/5 = 8
(multiply through by x)
6 + 2x/5 = 8x
(minus 8x from both sides)
-38x/5 + 6 = 0
(subtract 6 from both sides)
-38x/5 = -6
(times by -1)
38x/5 = 6
Times 6 by 5 and then divide by 38.
=15/19

Alia buys a computer. The original price of the
computer is $379.99. She uses a coupon for 15%
off any item. She must pay 6.75% sales tax on the
sale price. How much money will Alia spend on the
computer? (Hint....tax goes on the sales price!)
Answer:
$344.79
Step-by-step explanation:
379.99 decrease 15% =
379.99 × (1 - 15%) = 379.99 × (1 - 0.15) = 322.9915
322.9915 increase 6.75% =
322.9915 × (1 + 6.75%) = 322.9915 × (1 + 0.0675) = 344.79342625

A box contains 2 red marbles 3 green marbles and 3 blue marbles if we choose a marble then another marble without putting the first one back in the box what is the probability that the first marvel will be green and the second will be blue
Answer: 9/56
Step-by-step explanation:
Make x the subject of y=x/3
This simply means moving everything possible thing off x and isolate it.
y=x/3
We see x is stuck with a divide by 3 so we need to get rid of that by multiplying by 3 on both sides.
y*3=x/3*3
switch left and right side and simplify
x=3y
Done! as simple as that.
The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking. Wow a statement that describes how the distance that you travel is determined. Then identify the independent and dependent variables if this function.
Answer:
The maintained speed while hiking= 3 miles per hour
Let t be the time which represent the independent variable.
Also we know that Distance= Speed × Time
⇒ Distance traveled while hiking=3 ×t=3t
Let h represent the distance function in miles, and h(t) the dependent variable.
Then h(t)=3t
When we put t=4
Then h(4)=3×4 =12 miles.

Why should the sum of the probabilities in a probability distribution always equal to 1?
Answer:
If u add probabilities of all possible outcomes that should be one, because classical definition of probability is number of possible out comes divided by total number of outcomes. When you add all probabilities numerator and denominator are equal so answer is one.
Answer:
The total probability of a set of related events sums up to 1 because the probability of each individual event in the set is a fraction of the whole. For example, suppose you flip a fair coin a large number of times.
