Answer:
153 cm²
Step-by-step explanation:
The area is given by the formula ...
A = (1/2)bh
where b is the base length, and h is the height measured perpendicular to the base.
The diagram shows b = QR = 18 cm, and h = 17 cm. So, the area is ...
A = (1/2)(18 cm)(17 cm)
A = 153 cm²
Answer:
(49 - 29) + 1 =(50 - 29)
Step-by-step explanation:
The 20 comes from the subtraction of 29 in both sides of the previous step equality. In the following, I transcript the complete procedure and I add the step that you need to understand why 20 appears (in bold numbers):
29+20=49
49+1=50
(49 - 29) + 1 =(50 - 29)
20+1=21
50-29=21
hence, it was only nesseraty to subtract 29
Hello: <span>
<span> an equation is : y =ax+b ( a is a slope )
parallel to the line (q) : y=6/5x-1 a =6/5 ( same slope
)
the equation of (r) : is : y = 6/5x+b</span></span>
the line through point (5,5) :
5= (6/5)(5)+b ...b=-1
an equation of (r) : is : y = 6/5x-1
or : 6/5x-y = 1
Answer: x = 2/7y + 3/7 and
x= -5/4y + 0.8125
Step-by-step explanation: Let's solve for x.
7x−2y=3
Step 1: Add 2y to both sides.
7x − 2y + 2y= 3 + 2y
7x = 2y + 3
Step 2: Divide both sides by 7.
7x/7 = 2y+3/7 this is for the second answer Step 1: Add -5y to both sides.
4x+5y+−5y=3.25+−5y
4x=−5y+3.25
Step 2: Divide both sides by
4/4 x 4 = −5y + 3.25/4
For a definite answer, let us take a look at the given circle graph. You are given that landing on a blue sector will give 3 points, landing on a yellow sector will give 1 point, purple sector will give 0 points and red sector will give -1 point. You are asked to find the probability of landing -1, 0, 1 and 3 points. There are a total of 7 pie graphs in the circle.
For -1 point, you know that only a red sector will give you a negative one point. In the circle graph, there are two red portions. So you will have a probability of 2/7.
For the 0 point, you know that only a purple sector will give you zero point. In the circle graph, there are two purple portions. So you will have a probability of 2/7.
For the 1 point, you know that only a yellow sector will give you one point. In the circle graph, there are two yellow portions. So you will have a probability of 2/7.
For the 3 points, you know that only a blue sector will give you three points. In the circle graph, only one blue portion is shown. So you will have a probability of 1/7.
