Three Duos is worth the same amount as two Trios. Steve has thirty-six Trios. If he converts all of his Trios to Duos, then how many Duos will Steve have?
Answer:
Steve has 54 Duos
Step-by-step explanation:
Proportions
It's given three duos (D) is worth as two trios (T), i.e.:
3D = 2T
Steve has 36 trios, that is, 36T. To find the equivalence to duos, we multiply the given relationship by 18:
18*3D = 18*2T
Operating:
54D = 36T
Therefore, 36 trios are equivalent to 54 duos.
Steve has 54 Duos
Find the measure of Angle A. (include and explanation so I could do the rest on my own, preferably :)
Answer:
13) Angle A is 30°
14) Angle A is 45°
15) Angle A is 40°
16) Angle A is 40.5°
Step-by-step explanation:
By the angle sum theorem for the interior angles of a triangle, we have;
13) 130° + 2·x + 3·x = 180°
∴ 2·x + 3·x = 180° - 130° = 50°
2·x + 3·x = 5·x = 50°
x = 50°/5 = 10°
∠A = 3·x = 3 × 10° = 30°
∠A = 30°
14) 3·x + 9 + 4·x + 9 + 78° = 180°
7·x + 18 + 78° = 180°
7·x = 180° - (18 + 78)° = 180° - 96° = 84°
x = 84°/7 = 12°
∠A = 3·x + 9 = 3 × 12° + 9 = 45°
∠A = 45°
15) 90° + x + 51 + x + 61 = 180°
∴ x + 51 + x + 61 = 180° - 90° = 90°
2·x + 112 = 90°
2·x = (90 - 112)° = -22°
x = -22°/2 = -11°
x = -11°
∠A = x + 51 = -11° + 51 = 40°
∠A = 40°
16) x + 79 + x + 49 + 70° = 180°
x + x = (180 - 70 - 79 - 48)° = -17°
2·x = -17°
x = -17°/2 = -8.5°
x = -8.5°
∠A = x + 49 = (-8.5 + 49)° = 40.5°
∠A = 40.5°.

Answer:
a is -6 and b is -4
Step-by-step explanation:
Since your slope is 5/2, it means the function will go up five units and to the right two units. Since we know this, we can see that a needs to be 4 spaces to the left of the second point, thus making it -6, and b needs to be 5 above the second point, thus making it -4

An 18-foot piece of rope costs $17.82. What is the price per yard?
The solution to the equation 4(3x - 8) = 10, rounded to the nearest tenth, is ______.
Answer: x= 3.5
Step-by-step explanation: 4(3x) = 12x
4(-8)= -32
12x - 32 = 10
+32 = +32
12x = 42
x = 3.5
Answer:
x=3.5
Step-by-step explanation:
Start off by using distributive property ---> 12x-32=10, then add 32 on both sides---> 12x=42, then divide 12 on both sides--->x=3.5 and that is the final answer!
I hope this helps, and have a great day!

A bag contains 15 balls numbered 1 through 15. What is the probability of selecting a ball that has an odd number and is divisible by 5? 1. 8/15 2. 2/15 3. 7/15 4. 1/5
Answer:
the probability would be 8/15
The solution is Option 2.
The probability of selecting a ball that has an odd number and is divisible by 5 is 2/15
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
Let the probability of selecting a ball that has an odd number and is divisible by 5 be P
Now , the equation will be
The total number of balls in the bag = 15 balls
The numbered balls in the bag A = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 }
The numbers of the balls in the bag that are divisible by 5 B = { 5 , 10 , 15 }
The odd numbers from the set B = { 5 , 15 }
So , the probability of selecting a ball that has an odd number and is divisible by 5 P = odd numbers from the set B / total number of balls in the bag
Substituting the values in the equation , we get
The probability of selecting a ball that has an odd number and is divisible by 5 P = 2/15
Therefore , the value of P is 2/15
Hence , the probability is 2/15

On the coordinate plane shown, what is the distance from point Y to point Z? Round your answer to the nearest hundredth.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would solve a similar question:
Find the distance between the two points shown on the coordinate plane. (Round your answer to the
nearest tenth.)
Solution:
The coordinate plane is a plane formed by the intersection of the vertical line and the horizontal line. The vertical line is known as the y axis and the horizontal line is the x axis. The y axis and x axis intersect at a point known as the origin.
The distance between two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is given by:
[tex]Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Given points (-2, -1) and (2, 3), the distance is:
[tex]Distance=\sqrt{(3-(-1))^2+(2-(-2))^2}=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{32}[/tex]
