Answer:
X = 64
Y = 18
Z = 98
Step-by-step explanation:
Angles on a straight line always add up to 180 Degrees
Vertical Opposite Angles are equal to each other
X = 64
Y = 18
Z = 180 - 64 - 18 = 98
-12 = -3y

There are 221 students on a field trip.
. Five students ride in a van.
. The rest of the students fill 6 buses.
Enter an equation that can be solved to find the number of students, s, that are on each bus. Enter your response in
the first response box.
Enter the number of students that are on each bus. Enter your response in the second response box.
The equation that models the students is a linear equation
The equation that models the number of students in each bus is 6x = 216, and the number of students in each bus is 36
How to determine the equation?The given parameters are:
Students = 221
Van = 5
The rest students = 6 buses
Start by calculating the number of students remaining:
Remaining students = 221 - 5
Remaining students = 216
Represent the number of students in each bus with x.
So, we have:
6 buses * x = Remaining students
This gives
6x = 216
Divide both sides by 6
x = 36
Hence, the equation that models the number of students in each bus is 6x = 216, and the number of students in each bus is 36

$400 interest is earned on a principal of $2000 at a simple interest rat 5% interest per year.for how many year was the principal invested
Answer:
4 Years.
Step-by-step explanation:
Given:Principle ⇒ 2000
Interest ⇒ 400
Rate ⇒ 5%
To Find:Time ⇒ _
Solution:Simple interest ⇒ p * x * t / 100
⇒ 400 = 2000 * 5 * t / 100
⇒ 400 = 200 * 5 * t / 10
⇒ 400 = 20 * 5 * t
⇒ t = 400 / 20 * 5
⇒ t = 40 / 2 * 5
⇒ t = 20 / 5
⇒ t = 4

Help me with this question on congruent triangles? 20 points
Answer:
a) 5.7 cm
b) 3.05 cm
Step-by-step explanation:
a)
Since BE is parallel to CD,
Then AB/AC = BE/CD
So Length of CD = 12.3/8.2 x 3.8 = 5.7 cm
b)
AB/AC = AE/AD
So length of AE = 8.2/12/3 x 9.15 = 6.1 cm
ED = AD - AE = 9.15 - 6.1 = 3.05 cm

Which of the above solids has the larger surface area?
O O A. Solid A
O
B. Solid B
C. They have the same surface area.
Answer:
Solid A
Step-by-step explanation:
Surface area of a cube: 6 x a², where a is the side.
= 6 x 6²
= 6 x 36
= 216 cm²
Surface area of the cuboid/rectangular prism: 2(lw + wh + lh), where l is the length, w is the width, h is height.
= 2((5 x 4) + (4 x 8) + (5 x 8))
= 2(20 + 32 + 40)
= 2(92)
= 184 cm²
Therefore, Solid A has the larger surface area compared to Solid B.

Step-by-step explanation:
A cube is sliced as shown. Find the area of the cross section formed by the slice.
Answer: 5√(50) = 35.36 m^2
Step-by-step explanation:
The cross section is a rectangle, so its area formula is: Area = length * width.
If you look, the width is the diagonal of the side of the cube; thus, you can use Pythagorean theorem to find its measurement: a^2 + b^2 = c^2 → 5^2 + 5^2 = c^2 →
50 = c^2 → c = √(50)
Now, use the area formula and get: Area = 5 * √(50) = 5√(50) = 35.36 m^2 :)
Felipe is making triangles for a stained glass window, he made the design shown but wants to change it. Felipe wants to move the purple triangle to the corner. The purple piece has side lengths of 4.5 inches, 6 inches, and 7 inches. Can the purple piece be moved to the corner?
We have sides of triangle as [tex]4.5[/tex] inches, [tex]6[/tex] inches and [tex]7[/tex] inches.
So the sum of square of two smallest side is-
[tex]=4.5^2+6^2[/tex]
[tex]=20.25+36[/tex]
[tex]=56.25[/tex]
Now lets find the value of square of longest side of triangle-
[tex]=7^2[/tex]
[tex]=49[/tex]
Now from both value
[tex]49[/tex] [tex]\neq[/tex] [tex]56.25[/tex]
[tex]7^2[/tex] [tex]\neq[/tex] [tex]4.5^2+6^2[/tex]
So from Pythagoras theorem the given triangle is not a right triangle so it can not moved to the corner.
Thus, Since the triangle is not a right triangle therefore it can not moved to the corner.

19.308
Step-by-step explanation:
The probability of throwing a sum of 10 at least 7 times in 9 throws of a pair of fair dice is 0.083
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
We assume that the probability of throwing a sum of 10 in a pair of fair dice is

Knowing that ΔBIG ≅ ΔFNS, an angle pair that is NOT necessarily congruent is:
Knowing that ΔDAL ≅ ΔEKS, a side pair that is NOT necessarily congruent is:
solutions:
1) G ≅ F
2) DA ≅ ES
Explanation:
Q)1
ΔBIG ≅ ΔFNS
pairs that are congruent:
B ≅ FI ≅ NG ≅ SFrom the list given,
→ G ≅ F is not necessarily congruent.
Q)2
ΔDAL ≅ ΔEKS
pairs that are congruent:
DA ≅ EKAL ≅ KSDL ≅ ESFrom the list given,
DA ≅ ES is not necessarily congruent.
Usually the congruence is done according to naming
So
∆BIG≅∆FNS<B=F
<I=<N
<G=<S
Option A#2
Check the naming
∆DAL≅∆EKSSo
DA=EK
And DA may not be equal to ESSo option D
An integer is chosen at random from 1 to 50 inclusive. Find the probability that the chosen integer is divisible by 3. 8/25 3/10 3/50
How many numbers from 1 to 50 are multiples of 3?
3, 6, 9, 12, 15, 18 .......
Let's change the start and end value of the array and find the number of terms
Start at 3 and go all the way to 48 because those are the first and last multiples of 3 in this array.
There is a formula that allows us to quickly find the number of terms
We subtract the first term from the last term and divide by the amount of increase, then we add 1.
(48 - 3) / 3 + 1 = 16 numbers are exactly divisible by 3.
We have 50 numbers and 16 of them divisible by 3
16 / 50 = 8 / 25 probability
The probability that the chosen integer is divisible by 3 is 8/25 if an integer is chosen at random from 1 to 50 inclusive option first is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have the number from 1 to 50.
Total numbers between 1 to 50 or total outcomes = 50
Total favorable outcomes = total number which is divisible by 3
[tex]=\frac{48-3}{3} +1[/tex]
= 15 + 1
= 16
Now probability will be:
= 16/50
= 8/25
Thus, the probability that the chosen integer is divisible by 3 is 8/25 if an integer is chosen at random from 1 to 50 inclusive option first is correct.
