Split the L into separate shapes. To do this, where the bit sticks out, cut it off and deal with it separately.

Step-by-step explanation:

just look at the objects !

they are completely regular, and each arm can cover every other other arm.

so,

15A needs 1/3 of a full rotation.

15B needs 1/2 of a full rotation.

15C needs 1/4 of a full rotation.

15D needs (can you guess ?) ... 1/6 of a full rotation.

Uncle Jason is twice as old as his nephew Ralph, and 10 years ago he was three times as old as Ralph. Find their present ages.

cluponka [151]

Answer:

40 and 20

Step-by-step explanation:

Uncle Jason's age = x
Nephew Ralph age = y

<h3>Solution</h3>

Age now:

x= 2y

Age 10 years ago:

x- 10 = 3(y-10)

Substituting x in the second equation:

2y - 10 = 3y - 30
3y - 2y = 30 -10
y = 20

Then, finding x:

x= 2y
x= 2*20
x= 40

Answer: Uncle Jason is 40 and nephew Ralph is 20 years old

Medical researchers have determined that for exercise to be beneficial, a person’s desirable heart rate, R, in beats per minute,

yan [13]

we are given with two equations: R=143-0.65a for women and R = 165-0.75a for men. In this prblem we are asked the age of a man when R is equal to 135. In this case, we use the second equation and substitute R with 135. In this case, 135 = 165 - 0.75 a; a is equal then to 40 yrs old. In 2, when x is equal to 4, then 0.5*4 + 3 is equal to 5.

Which algebraic expression is a polynomial with a degree of 5?

Eddi Din [679]

The degree of a polynomial is the highest exponent or sum of exponents of the variables in the individual terms of a polynomial.

Looking at each the polynomial:

3x5 + 8x4y2 – 9x3y3 – 6y5: Degree is 6 (look at the 2nd and 3rd term)

2xy4 + 4x2y3 – 6x3y2 – 7x4: Degree is 5 (look at 1st, 2nd, and 3rd term)

8y6 + y5 – 5xy3 + 7x2y2 – x3y – 6x4: Degree is 6 (look at 1st term)

–6xy5 + 5x2y3 – x3y2 + 2x2y3 – 3xy5: Degree is 6 (look at 1st and last term)

Therefore, the answer is the second option:
2xy4 + 4x2y3 – 6x3y2 – 7x4
