calculate the value of 1/3 a = -5
Answer:
- 15
Step-by-step explanation:
[tex] \frac{1}{3} a = - 5 \\ \\ a = - 5 \times 3 \\ \\ a = - 15[/tex]
Answer:
-15
Step-by-step explanation:
As you can see, the denominator of 1/3 is 3. 1 third of a is -5. So what you do is, you multiply -5 * 3 and that'll give you -15. So, it is equal to -15.

Step-by-step explanation:
Stacy reasons that since dilations change lengths they also change angles by the same factor. Is she correct? If not, explain why, I will list brainlist if you reply fast
Answer:
Stacy is incorrect. Dilations do not affect the angles of a given figure since dilations create parallel lines and the angles on parallel lines are congruent.

Answer:
130°
Step-by-step explanation:
∠JDG and ∠EDF are opposite angles. The measures of arcs for opposite angles always add up to 180°. Since the arc for ∠JDG is 50°, the arc for ∠EDF has to be 130°, because 50 + 130 = 180.

Answer:
A) 130°
Step-by-step explanation:
Angle UTV = angle YTX = 75°
Angle VTW = 55°
so UTW = 75 + 55
if this helps, please give brainliest if possible
Answer:
A
Step-by-step explanation:
∠ UTV = ∠ YTX = 75° ( vertically opposite angles )
∠ VTW = 55° ( angle at centre is equal to arc that subtends it )
Then
∠ UTW = ∠ UTV + VTW = 75° + 55° = 130° → A

Roman was studying the life of fish, frogs, and turtles in
Doyle Park. In two hours, he counted 4 more frogs than
turtles. The number of fish he counted was twice the
number of turtles. In total, he counted 68 animals. How
many fish were there?
how many frogs were there? how many turtles were there?
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish

Step-by-step explanation:
We can see that the y intercept is equal to 1
which means that we have the following equation
mx+1=y
We just need to solve for m at this point
We can use the ordered pair (-2,2) to help
We know that
-2m+1=2
Solve for m
-2m=1
m= -1/2
Put this together and we get
-1/2m+1=y which is A

A train is traveling at a constant speed and goes 17 kilometers in 8 minutes. How far will the train travel in 60 minutes.
Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
Distance B = 1275 km
