Use the Distributive Property to simplify the expression.I GIVE BRAINLEST AWNSER
6(6+y)
Answer:
36+6y
Step-by-step explanation:
you have to multiply 6 on 6+y because distributive property basically means to share out so you do 6(6)+(6)y
6(6) equals 36 (6x6) and 6(y) is just 6y
36+6y
Angles a and b are complementary angles symmetry of angle a is 28° more than the measure of angle b find the missing angle measures
Answer:
31 , 59
Step-by-step explanation:
a = b +28
a + b = 90 {Complementary}
b + 28 + b = 90 {Combine like terms}
2b + 28 = 90 {Subtract 28 form both sides}
2b = 90 - 28
2b = 62 {Divide both sides by 2}
b = 62/2
b = 31
a = 31 + 28
a = 59

How many 5-card hands can be dealt from a standard deck of 52 cards?
Answer:
2,598,960
Step-by-step explanation:
Answer:
The 2598960 cards can be dealt from a standard deck of 52
cards if 5-card selected.
What is permutation and combination?
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have a standard deck of 52 cards.
5 cards selected.
Total combination:
= C(52, 5)
= 2598960
Thus, the 2598960 cards can be dealt from a standard deck of 52
cards if 5-card selected.

If two angle measurements are 53° and 70,° what must the third angle measurement equal to form a triangle?
Answer:
Step-by-step explanation:
All triangles without exception, have 180 degrees.
x + 53 + 70 = 180 Add the left
x + 123 = 180 Subtract 123 from both sides.
x + 123 - 123 = 180 - `123 Combine.
x = 57

what is 2 x 1 1/2
Answer:
3
Step-by-step explanation:
2 times 1 is 2 and then multiply 1/2 by 2 and you'll get 1 then add those two numbers together and you will get 3. Note: The best way to do these types of things in multiplication is to split the numbers up among the decimal places so if you did 15 times 4 then an easy way to do it would be to split the 15 with 10 and 5 so then multiply the 10 by 4 and you get 40 now do the same to the 5 and you get 20 so now add those two numbers together and you get 60(This has nothing to do with the answer i just want to help make it easier for future problems such as this).

A trebuchet launches a pumpkin on a parabolic arc from a height of 47 ft at a velocity of 40 ft/s which gives the
following function equation h(t)= -16t^2 + 40t + 47. State the vocabulary term that is being described by the
following questions. Do not solve for any of the key features. questions a b c and d
a. When will the pumpkin reach the ground?
The pumpkin will reach the ground at
b. What is the maximum height the pumpkin reaches?
C. When does the pumpkin reach its maximum height?
d. What is the starting height of the pumpkin?
Answer:
a) 3.37 seconds
b) 75.85 feet
c) 1.25 seconds
d) 47 feet
Step-by-step explanation:
a) I could use kinematic equations here, but I'll use the one provided. Height as a function of time equals 0 when the pumpkin reaches the ground, so 0=(-16t^2)+40t+47 is your equation here. Solve for t. t=3.37
b) If you have a graphing calculator, just use maximum feature. If not, use the formula x=-b/2a. x=-40/-32, x=1.25.
Now, plug 1.25 in as t, and you'll get y=75.85ft
c) alreaady found in previous part
d) this is the constant in the formula, or the y-intercept, which is 47 (because there's no variable attached).

Step-by-step explanation:
Question: On a recent day,8 euros were worth $11 and 32 euros were worth $44 .Enter an equation of the form Y = KX To show the relationship between the number of euros and value in dollars.let y be the value in dollars and x be the numbers of euros.
Notes:
8 euro= $1132 euro= $44Need: Enter an equation of the form Y = KX To show the relationship between the number of euros and value in dollars.let y be the value in dollars and x be the numbers of euros.
In Y = K X
| |
| numbers of euros.
value in dollars
Our first number: 8 euro = $11
Y=11
X=8
Then Convert:
11=K8
11=K*8 ---> 8*K=11
8K=11
11/8= 1.3
K=1.3
