Answer 1

Answer:

Answer:

5/6

Step-by-step explanation:

first form numerator you will multiply by π it means 3.14 multiply 11

the answer equals 34.54 ..and then you will use √ it means square root....so the answer is 5

the annwer is

5/6

Answer 2

Answer:

Answer:

Step-by-step explanation:

$(11\pi )/(6)$ = 11 × $(\pi )/(6)$ = (12 - 1) × $(\pi )/(6)$

Use a transformation to solve the equation. k/-4 = - 0.8

A.

k = –3.2

B.

k = –0.2

C.

k = 0.2

D.

k = 3.2

Answers

k/-4 = - 0.8,
make k the subject of the equation by multiplying through by -4,
   this means, (k/-4) x -4 = - 0.8 x -4
   this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
   so k= 3.2

your answer is D

The Joneses are moving from San Francisco to South Africa. They pack their belongings in rectangular crates and hire a boxcar to ship the crates across land and sea. The crates are made specifically to fit inside the boxcar with their bases facing down. Each crate has a base 15 ft long by 5 ft wide and height 6.5 ft. The boxcar is 60 ft long, 10 ft wide and 13 ft high. How many crates can The Joneses fit into one boxcar?

Answers

La sup della base del box e' :
S box=60 x10=600
S crate =15 x5=75
Sulla base del box si possono mettere 600/75=8 crate
Sull' altezza (high) si possono mettere 13/6,5=2 strati
8( crate/ strato) x 2 (strati)=16 crates

Answer:

16 crates if i am right

Solve each system of equations by graphing y=-1/2x+5 and y=3x-2

Answers

just make the equations equal to each other. -0.5x+5=3x-2. Solve for x and find that it is 2, via simple algebra. Since you know x is 2, sub it in in either equation to find y. y should be 4. So the point that fits both equation is (2,4). This shows that the two graphs of these lines will intersect at this exact point.

If you were to graph these two lines, you ould see that the point of intersection is at (2,4) like we solved for.

Isabella is solving the equation 4x2 = 13x – 3 with the quadratic formula. What values should she use for a, b, and c?

a. a = 4
b= 13
c = –3

b. a= 4
b = –13
c = 3

c. a = 4
b = –3
c = 13

d. a = 4
b = 3
c = –13

Answers

we know,
standard form of quadratic equation,
ax² + bx + c =0-----------(1)

here given ,

4x² = 13x -3
4x² -13x +3 =0 -----------(2)

compare both the equations ,
then ,
a = 4
b = -13
c = 3

hence, option ( b) is correct
