Answer:
142
Step-by-step explanation:
∠2=38 ( corresponding angles)
definition: the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
sum of straight angle=180
∠5+∠2=180
∠5+38=180
∠5=180-38=142 degrees

HURRY I NEED HELP ASAP 30 POINTS Beginning at the origin, how far do you travel along the x-axis when plotting the point below? (15,5)
Answer:
You travel 15 units of distance along the x-axis
Step-by-step explanation:
You want the distance from (0, 0) to (15, 5) in the x-axis. It is 15. If the question were the distance between the two points, you may use the distance formula or pythagorean theorem.
Driving on the highway, you can safely drive 65 miles per hour. Which of the following functions could be used to find how far you can drive in 'h' hours?
a. D = 65h
b. D = 65 + h
c. D = 65/h
d. D = h/65
Answer:
The answer is A, D=65h
Step-by-step explanation:
This is because D is representing how far you drove, so you can only drive 65 mph. And that will be 65*h=D. Hope this helps!
The solution is Option A.
The distance traveled is calculated by Distance D = 65h , where h is the number of hours
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the distance traveled be represented as D
Now , the value of D will be
Let the speed be represented as S = 65 miles per hour
Let the time required to travel a distance of D be represented as = h
where h is the number of hours
So , the distance D is calculated from the formula
Speed = Distance traveled / Time required
Substituting the values in the equation , we get
65 = D / h
Multiply by h on both sides of the equation , we get
D = 65h
Therefore , the value of D is 65h
Hence , the equation will be D = 65h where h is the number of hours and D is the total distance

In the circle below, O is the center and mJL = 55°. What is the measure of the central angle JOI?
Answer: 55 degrees
By definition of how the term "central angle" is defined, it is simply equal to the arc measure it cuts off. The central angle JOI subtends or cuts off the minor arc JI which is 55 degrees, so the central angle is also this measure as well.
Put another way, minor arc JI is 55 degrees of a full 360 degree rotation, and so is the angle JOI.
A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 5 milliliters of compound B. If a chemist wants to make 576 milliliters of the drug, how many milliliters of compound A are needed?
Answer: 216 millilitres
Step-by-step explanation:
From the question, you are given that there are 3 milliliters of compound A used for every 5 milliliters of compound B. That means compound A and B are in ratio 3 to 5. That is,
A : B = 3 : 5
If a chemist wants to make 576 milliliters of the drug, then find the ratio of compound A.
To do that, first add the ratio of both together, 3 + 5 = 8
For compound A,
3/8 × 576
1728/8 = 216 millilitres
Therefore, 216 millilitres of compound A are needed.

Best regards!!
The measure of angle <PSQ is 62 degrees.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
We have to find the measure of angle ∠PSQ
The arc measures PQ = 47° , RT = 77°
now, let's find the measure of <PSQ
<PSQ = 1/2(PQ+RT)
= 1/2(47+77)
= 1/2(124)
When one hundred twenty four is divided by two we get 62
<PSQ =62
Hence, the measure of angle <PSQ is 62 degrees.

The ratio of girls to boys at a local elementary school is 3:4.
a. If there are a total of 45 girls in the school, how many boys are there?
b. At another school across town, the ratio of girls to boys is 5:7. How many total
students are there in the school if there are 95 girls at that ratio?
Answer:
a. 60 boys
b. 228 total students
Step-by-step explanation:
a. If there are 45 girls and the ratio of girls to boys is 3:4, then there are 60 boys. The common multiple is 15.
3 * 15 = 45
4 * 15 = 60
45:60 = 3:4
——————————
b. First we need to find out how many boys there are.
95 / 5 = 19
19 * 7 = 133
So, there are 133 boys and the given number of girls is 95. To find out how many total students there are, we need to add 133 and 95.
133 + 95 = 228
