Answer:
x=3
Step-by-step explanation:
Because the shape is a rhombus that means that WZ and XY are parallel
This means we can use the co-interior angles rule to conclude that ∠WZY and ∠XYZ add up to 180°
This means that ∠WZY is 44°
Because the shape in a rhombus ZX and WY are perpendicular
This means that ∠ZRY is a right angle (90°)
Because ZX and WY are perpendicular that means that ∠ZYX is split in half which makes ∠ZYW 68°
Because the angles in a triangle add up to 180°
(10x-8)+68+90=180
(10x-8)+158-158=180-158
10x-8+=22+8
10x/10=30/10
x=3
A 20-foot ladder leans up against the side of a building so that the foot of the ladder is 10 feet from the base of the building. How far up the
building does the ladder reach? Round your answer to the nearest tenth.
18.1
17.3
15.9
16.4
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
[tex]a^{2} +b^{2}= c^{2}[/tex]
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
[tex]10^2+b^{2} =20^{2}[/tex]
Then, use the squares in the equation:
[tex]100+b^{2} =400[/tex]
Then, subtract 100 from both sides to isolate b:
[tex]b^{2} =300[/tex]
Finally, square root both sides to get your answer:
[tex]b=17.3205080757[/tex]
Then round to the nearest tenth which gives you 17.3.

On February 4th, Kyrie Irving scored a total of 16 points, making a total of 7 shots. He scored all his points on 2-point and 3-point shots. How many of each type of shot did he make
Answer:
2 point shot = 5
3 point shot = 2
Step-by-step explanation:
Given that:
Total score = 16
Total shots = 7
Let:
2 point shot = x
3 point shot = y
x + y = 7 - - - (1)
2x + 3y = 16 - - - - (2)
From (1):
x = 7 - y
Put x = 7-y in (2)
2(7 - y) + 3y = 16
14 - 2y + 3y = 16
14 + y = 16
y = 16 - 14
y = 2
x = 7 - 2
x = 5
2 point shot = 5
3 point shot = 2

the two lines below are parallel if the slope of the red line is 5 what is the slope of the green line
Answer:
5
Step-by-step explanation:
Since the two lines are parallel, they must have the same slope. This means that the slope of green line must be 5 just like the red line. You can also use the slope formula (rise/run) or change in y divided by change in x.

many kids came to the party?
2. Rosa got 20% of an 80 item test incorrectly. How many items did she get
correctly?
3. There were 50 pupils in Grade Ill. If 28% of the pupils were absent, how many
pupils were present?
4. Out of 50 pupils, only 48 pupils joined the educational fieldtrip. What percent
joined the trip?
5. Among the 50 pupils in a Grade 6 class, 6% are left-handed. How many are left-
handed?
1.
300 x 0.15 = 45
300 - 45 = 255
255 kids came to the party
//
2.
80 x 0.20 = 16
80 - 16 = 64
She got 64 items correctly
//
3.
50 x 0.28 = 14
50 - 14 = 36
36 pupils were present
//
4.
48 / 50 = 0.96
0.96 x 100 = 96.0%
96% joined the trip
//
5.
50 x 0.06 = 3
3 pupils are left handed
