Answer:

Let the larger number = y and the smaller number = x.

The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,

y = 2x - 10

The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,

x + y = 38

Since y = 2x - 10, we rewrite the lower equation as:

x + (2x - 10) = 38

Solving:

3x - 10 = 38

3x = 48

x = 16

The lesser number is 16 and the greater number is 2(16) - 10 or 22.

Answer:

y = -x + 9

Step-by-step explanation:

Since the line is going down, you can safely assume that it is a negative slope function.  The y-intercept is at (0, 9), so your final slope function should be y = -x + 9.

Answer:

−31π/36 = -15.5°

Step-by-step explanation:

We need to convert −31π/36 to degrees.

The conversion from radian to degrees is calculated as follows :

[tex]\text{Degrees}=\dfrac{180}{\pi }\times \text{radian}\\\\=\dfrac{180}{\pi}\times \dfrac{-31\pi }{360}\\\\=-15.5^{\circ}[/tex]

So, −31π/36 is equal to -15.5 degrees.

Given that if x = 7 and y = 4, the value of x + 2y = 15

Given the following:

x = 7

y = 4

Required:

Find the value of x + 2y.

Therefore, substitute x = 7 and y = 4 into the algebraic expression, x + 2y.

(7) + 2(4) = 7 + 8

x + 2y = 15

Therefore, given that if x = 7 and y = 4, the value of x + 2y = 15

-- the answer is the third choice.

Answer: The answers are all of the options except for B.

Step-by-step explanation:

Option A. 4/1 x 4/3 is 16/3. 16/3 > 1

Option B. 1/3 x 1/10 is 1/30. 1/30 < 1

Option C. 5/6 x 5/2 is 25/12. 25/12 > 1

Option D. 25/8 x 8/23 is 200/184. 200/184 > 1

Option E. 9/7 x 7/8 is 63/56. 63/56 > 1

Hence, the correct answer is option A, C, D, and E.

Answer:

The answer is c.

Step-by-step explanation:

This is because the slope is a negative, and since letter a, has a positive slope, it's out of the picture. Just by the looks of b, you can tell that the why intercept isn't 5. It looks like its y-intercept is 0. Letter d, also doesn't have a positive y-intercept so it's also out of the picture. Which leaves letter c. It has a positive slope and it looks like it has 5 as a y-intercept.

The respective unit rates are 6,9,7

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: Cam 1 clicks 30 pics in 5 secs

∴ Unit rate of Cam 1= 30/5

                                  =6 pics/sec

Similarly we can find

Unit rate of Cam 2=9 pics/sec

Unit rate of Cam  3= 7 pics/sec

Hence, The respective unit rates are 6,9,7

Step-by-step explanation:

The number of students taken only one course is 106

A Venn diagram exists as an illustration that utilizes circles to illustrate the relationships among things or finite groups of things. Circles that overlap include a commonality while circles that do not overlap do not share those traits. Venn diagrams permit visually illustrating the similarities and contrasts between two concepts.

Let M =sets of students who had taken mathematics

     C= sets of students who had taken chemistry

     P= represent sets of students who had taken physics

From the given information, we have

n(M) = 64 , n(C) = 94, n(P) = 58,

n(MnP) = 28, n(MnC) = 26, n(CnP) = 22

n(MnCnP) = 14​​​​​​​

No. of students who had taken only Math :

= n(M) - [n(MnP) + n(MnC) - n(MnCnP)]

= 64 - [28+26-14]

= 64 - 40

= 24​​​​​​​

No. of students who had taken only Chemistry

= n(C) - [n(MnC) + n(CnP) - n(MnCnP)]

= 94 - [26+22-14]

= 94 - 34

= 60

No. of students who had taken only Physics

= n(P) - [n(MnP) + n(CnP) - n(MnCnP)]

= 58 - [28+22-14]

= 58 - 36

= 22

Total no. of students who had taken only one course

= 24 + 60 + 22

= 106

Step-by-step explanation:

The team can expect to win 6 matches.

A ratio is a way to show a relationship or compare two numbers of the same kind. We use ratios to compare things of the same type.

Given that, The ratio of wins to losses for the spartan football team is 3:5. and this trend continues, they play a total of 16 games,

Let they won 3k games and loose 5k games.

Then,

3k+5k = 16

8k = 16

k = 2

Therefore, they lose 5·2 = 10 matches and won 3·2 = 6 matches.

Hence, the team can expect to win 6 matches.
