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

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.

Answer:

273.7

Step-by-step explanation:

first fine the sides that isn't the base.

triangle area formula: (b*h)/2

(14*9)/2 = 63

since there are 3 sides you multiply this by three.

63*3=189

then find the base.

same formula since its a triangle.

(12.1*14)/2 = 84.7

now add them both up:

84.7+189 = 273.7

Step-by-step explanation:

To find : Measure of <PSQ

Given,

PQ = 47° , RT = 77°

now, let's find the measure of <PSQ

<PSR = [tex] \frac{1}{2} (47 + 77)[/tex]

calculate the sum

[tex] = \frac{1}{2} \times 124[/tex]

Calculate the product

[tex] = 62 \: [/tex] °

Hope this helps..

Best regards!!

The measure of angle <PSQ is 62 degrees.

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.

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.

Answer:

9

Step-by-step explanation:

The average is just another word for mean. You get the mean by adding all the numbers in a data set and then dividing by the number you added.

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.

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

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
