A student can take three subjects in 40 ways.

<u>SOLUTION:</u>

Given that, there are 4 different math courses, 5 different science courses, and 2 different history courses.

A student must take one of each, how many different ways can this be done?

Now, number ways to take math course = 4

Number of ways to take science course = 5  

Number of ways to take history course = 2

So, now, total possible ways = product of possible ways for each course = 4 x 5 x 2 = 40 ways.

Hence, a student can take three subjects in 40 ways.

PLEASE ANSWER ANY PROBLEM ASAP THANK YOU SO MUCH
Mashcka [7]

Answer:

1) No

2) Yes

3) angle UXS = 120 degrees

4) arc CB = 40 degrees

Step-by-step explanation:

If AB is tangent to the circle, then angle at A would be 90 degrees.

1)

Is 13^2 + 14.6^2 = 19.4^2?

169 + 213.16 = 376.36      No

2)

Is 8^2 + 6^2 = 10^2?

64 + 36 = 100      Yes

3)

arc WS = arc VU + arc TU = 113 degrees

arc ST = arc WV because their chords cross making a pair of vertical angles.

full circle = 360 degrees

360-113 - 113 = 134 degrees

134/2 = 67 degrees for arc ST

arc STU = 67 + 53 = 120 degrees

Angle UXS = 120 degrees

4) arc CB = arc FB =  40 degrees because their chords cross making a pair of vertical angles.

Polygon ABCD reflects about line to make polygon EFGH. What is the length of ? A. 2 units B. 2.2 units C. 3 units D. 3.2 units
Mademuasel [1]

Answer:

A) LEngth of FG is 2 units

Step-by-step explanation:

Considering the diagram attached below.

Reflection of any polygon does not affects its length.

As it is given both polygons are reflection of each other so their sides are congruent.

AB ≅ EF = 3 units

BC ≅ FG = 2 units

CD ≅ GH = 2.2 units

DA ≅ HE = 3.2 units

Which number is in the solution set of this equation? 7x − 9 = 40
skad [1K]

Answer: the answer is 7

Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40

7(7)=49 next 49-9= 40

it checks out, so x= 7
