C+2D in standard form.
9514 1404 393
Answer:
C +2D = 3s -21
Step-by-step explanation:
Use the substitution property of equality.
C = s -5
D = s -8
Then the value of your expression is ...
C +2D = (s -5) +2(s -8)
= s -5 +2s -16
C +2D = 3s -21
A school committee needs 2 more students. How many ways can the committee be selected from a group of 10 students? 45 90 20 100
Answer:
45 ways
Step-by-step explanation:
The number of ways the committee of 2 can be selected from a group of 10 may be found using the combination theory.
10 C 2
Recall that n C r = n!/(n-r)!r!
Hence
10 C 2 = 10!/(10 -2)!2!
= 10!/8!*2!
= 10 *9 *8!/8!* 2!
= 10 *9/2 * 1
= 90/2
= 45

45

the sum of two numbers is 38 and their difference is 10 find the numbers
Answer:
I believe the two numbers are 14 and 24
Answer:
Those numbers are 14 and 24.
Step-by-step explanation:
You can solve this pretty quickly by taking those two facts and combining them:
a + b = 38
a - b = 10
Let's solve the second one for a:
a = 10 + b
Now we can substitute that into the first one:
a + b = 38
(10 + b) + b = 38
2b + 10 = 38
2b = 28
b = 14
To find a, we can plug that back into one of the original equations:
a + b = 38
a + 14 = 38
a = 24
We can also test our answer by plugging the results into the other given equation and see if we get the same value:
a - b = 10
24 - 14 = 10
10 = 10
So we know our answer is correct.

Answer: 60 is the answer.
Step-by-step explanation: We can use the total sum, 180.
To get the missing angle, add the 2 angles, 60 and 60.
60 + 60 = 120.
Then subtract from 180.
180 - 120 = 60.
Hence, 60 is the answer.
Let me know if you have any questions.

Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca. Is he correct, if the sandwich sizes are different.
Answer:
Riley is correct
Step-by-step explanation:
Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca.
To find out the fraction of how much more Riley ate than Luca, we carry out Subtraction operation
= Fraction of what Riley ate - Fraction of what Luca ate
= 5/6 - 3/6
Lowe's Common Denominator = 6
= 5 - 3/6
= 2/6
Therefore, Riley is correct

James and Martha are discussing special right triangles. James believes that a 30-60-90 triangle with a hypotenuse of 10 feet has a greater perimeter than a 45-45-90 triangle with a hypotenuse of 10 feet. Martha disagrees. Who is correct?
Answer:
Step-by-step explanation:
Disclaimer it is up the student to verify all the geometry algabra and mathematical formulas and calculation .
cosФ = opp/hyp sinФ = adj/hyp hyp = 10 perimeter = a + b + c
for the 45° right triangle
a = b so 2a² = hyp² perimeter 45 = a + a + hyp
P45 = 2a + hyp a = sin(45) (hyp) = [1/2√2)] (hyp) sin(45) = (√2)/2
P45 = 2([1/2√2)] (hyp) + hyp
P45 = hyp (√2 + 1)
for the 30° right triangle
a = hyp×sin(30) b = hyp×cos(30) perimeter 30 = a + b + hyp
sin(30) = 1/2 cos(30) = (√3)/2
a = hyp(1/2) b = hyp(1/2)(√3)
P30 = a + b + hyp
= hyp(1/2) + hyp(1/2)(√3) + hyp
= hyp[ 1/2 + (1/2)√3 + 1]
= hyp[ 1/2 + (1/2)√3 + 1] factored out the hyp
= (1/2)hyp[ 1 + √3 + 2] factored out a 1/2
P30 = (1/2)hyp[ 3 + √3]
which is greater P45 or P30? vso I set both perimeters equal to each other
P45 vs P30
hyp (√2 + 1) = (1/2)hyp[ 3 + √3] the hyp cancel
(√2 + 1) = (1/2)[ 3 + √3] still tough to tell needed
1.414 + 1 = (1/2)[ 3 + 1.732] to go to the calsulator
2.414 vs 1/2( 4.732)
2.414 > 2.366 thus P45 > P30 < ----- Final Answer

Suppose it takes 2 1/2 h to drive from your house to the lake at 48 mi/h. How long will your return trip take at 40 mi/h?
Answer
The distance from the house to the lake is (2.5 hr)*(48 mi/hr) = 120 miles. The rerurn trip would take (120 mi)/(40 mi/hr) = 3 hours. Distance equals rate times time, so the distance to the lake is 2 1/2 hours times 48 miles per hour.

Two semicircles are attached to the sides of a rectangle as shown.
(WILL GIVE BRAINLY IF RIGHT)
What is the approximate area of this figure?
Use 3.14 for pi.
Enter your answer in the box. Round only your final answer to the nearest whole number.
Answer:
157 in²Step-by-step explanation:
The area of the shape is the sum of three sections
1. Rectangle
A = 5*14 = 70 in²2. Bigger semicircle
A = 1/2π(14/2)² = 76.96 ≈ 77 in² (rounded)3. Smaller semicircle
A = 1/2π(5/2)² = 9.8174 ≈ 10 in² (rounded)Total area:
70 + 77 + 10 = 157 in²answer:
157 inches²
step-by-step explanation:
we have to break this down into parts and find the area of each part and then add them up so we have the area for the whole thingrectangle:
5 X 14 = 70 inches²
big semicircle:
solve this like a simple circle and then divide by 2 since this is halfarea = πr²
insert what we know from the questionarea = (3.14)(7)²
the radius would be seven because as you can see the length of a side of the rectangle is 14 and this is also the diameter of the circle since they are attached and share itthe radius is half of the diameter so we get 7area = 3.14(49)
= 153.86 inches²
now divide this by 2 since it is semicircle153.86 / 2 = 76.93 inches²
small semicircle:
area = (3.14)(2.5)²
i followed the same method as last, except the numbers are differentarea = 3.14(6.25)
= 19.625 inches²
now divide by 219.625 / 2 = 9.8125 inches²
finally, add up all the separate areas you got70 inches² + 76.93 inches² + 9.8125 inches²
= 156.7425 inches²
= 157 inches²
