Can someone please help me out I am so confused

Answer:

28 feet long together

Step-by-step explanation:

in 1 yard there is 3 feet so in 4 yards it would be 3(4) which is 12. add 12 to 16 and you get 28

Answer:

28 feet

Step-by-step explanation:

A yard is 3 feet, so

4 yards*3 feet=12 feet.

12 feet+16 feet=28 feet

Check if your school has given you a conversion sheet to use. Some schools might also ask you to memorize it, but it's pretty simple. Hope this helps and good luck on your endeavours.

Answer:

No real number solutions.

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

The discriminant is b² - 4ac

• If b² - 4ac > 0 the equation has 2 real and distinct roots

• If b² - 4ac = 0 the equation has 2 real and equal roots

• If b² - 4ac < 0 the equation has no real roots

Given

2x² + 4x + 8 = 0 ← in standard form

with a = 2, b = 4 and c = 8, then

b² - 4ac = 4² - (4 × 2 × 8) = 16 - 64 = - 48 , thus

The equation has no real number solutions because the discriminant is < 0

Answer:

It's c

Answer: The volume is 3560.76 in^3   or 1134π

Step-by-step explanation:

The formula for the volume of a cylinder  is  πr^2*h

so the radius is 9 and the height is 14 so we will put that into the formula  and solve.

v=3.14 * 9^2 * 14

v= 3.14 * 81 *14

v = 3560.76 in^3  or 1134π

Answer:

9 months.

Step-by-step explanation:

Well we subtract the one time fee of $150 from $420

420-150=270

Now we need to divide $270 by $30, the price she pays every month.

270÷30=9

She has had the service for 9 months.

The measure of angle BCD in circle A is 74°.

A circle is the locus of a point such that its distance from a fixed point is constant.

From the circle:

BC = CD (tangents that meet at the same point are equal)

But ∠ABC = 90° (angle between tangent and radius)

In triangle ABC:

∠ABC + ∠BCA + ∠BAC = 180 (triangle)

90 + ∠BCA + 53 = 180

∠BCA = 37°

Hence:

∠BCA = ∠ACD = 37°

angle BCD = ∠BCA + ∠ACD = 37 + 37 = 74°

The measure of angle BCD in circle A is 74°.

Answer:

Arithmetic.

Step-by-step explanation:

See if it's arithmetic:

2/3 - 1/3 = 1/3

1  - 2/3 = 1/3

4/3 - 1 = 1/3

-  common difference of 1/3 so it's arithmetic.

Answer:

9) not factorable

10) not factorable

Step-by-step explanation:

that's probably why you were having a hard time (-_-)

Answer:

a) Row 5: 75 - 216 - 51

b) 3n² - (n+1)³ - (71-4n)

c) 3(n+1)² - (n+2)³ - (67-4n)

Step-by-step explanation:

Column 3:

Arithmetic sequence with common difference: 63-67 = -4

an = 67 + (n-1)(-4)

an = 67 - 4n + 4

an = 71 - 4n

Row 5: 3×5² - (5+1)³ - (71-(5×4))

Row 5: 75 - 216 - 51

Row n: 3n² - (n+1)³ - (71-4n)

Row n+1: 3(n+1)² - (n+1+1)³ - 71-4(n+1)

Row n+1: 3(n+1)² - (n+2)³ - (67-4n)

Answer:

Column 1

Tn= 3n²

row n= 3n²

row n+1= 3(n+1)²

When n=5,

T₅ = 3(5)²

T₅ = 75

Thus, row 5= 75

Column 2

Tn= (n+1)³

row n= (n+1)³

row n+1

= (n+1+1)³

= (n+2)³

When n=5,

T₅ = (5+1)³

T₅ = 6³

T₅ = 216

row 5= 216

Column 3

Notice that the terms decrease by 4 with each row.

This means that there is a common difference of -4.

Common difference formula

Tn= a +d(n-1)

where a is the first term and d is the common difference.

Tn= 67 -4(n-1)

Now, simplify the formula

Tn= 67 -4n +4

Tn= 71 -4n

Row n= 71 -4n

Row n+1

= 71 -4(n+1)

= 71 -4n -4

= 67 -4n

when n=5,

T₅= 71 -4(5)

T₅= 51

Row 5= 51

Row n is the general formula for the pattern. To find the n+1 row, susbt. n+1 into n in the formula in row n.

Answer:

Not 100 percent sure but i think the correct answer is the last one.

Step-by-step explanation:

I know that the answer is either the last one or before the last because they are dependent on each other. This is because the probability of both increases when they are added together. The more you have the more likely to get one of them. I went for the last one because i think that the value of together is greater than when they are added.

Again, not 100 percent sure, tried to give it my best shot.

Hope this helps.

Answer:

Lauren made her first error in step 3 because she should have used 85 minus 60 = 25 for chemistry and 80 minus 60 = 20 for biology.  

Step-by-step explanation:

Lauren's box plots may have looked like those below.

Step 1

Chemistry median = 80

Biology median      = 70

Correct.

Step 2

Difference in medians = 80 - 70

Correct

Step 3

Chemistry IQR = 85 - 60 = 25

Biology IQR     = 80 - 60 = 20

Wrong.

This is where Lauren made the mistake.

She was finding the difference between the Max and Q3.

Answer:

1023

Step-by-step explanation:

[tex]8^{0}[/tex] = 1, [tex]8^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{8}[/tex] = 2, [tex]8^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{8^2}[/tex] = 4, [tex]8^{1}[/tex] = 8

The series can be expressed in non exponent terms as

1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 ← 10 terms

There is a common ratio r between consecutive terms, that is

r = 2 ÷ 1 = 4 ÷ 2 = 8 ÷ 4 = .... = 2

This indicates the sequence is geometric with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]

where a is the first term and r the common ratio

Here a = 1 and r = 2, thus

[tex]S_{10}[/tex] = [tex]\frac{1(2^{10}-1) }{2-1}[/tex] = 1024 - 1 = 1023

Step-by-step explanation:

The 24 inch shelve is 2 feet ( 1 foot = 12 inches)

She bout 7 feet of shelves (5 + 2 = 7)

The total cost for the shelves was 7 x 1.25 = $8.75

She spend an additional 90 so her total spent was 90 + 8.75 = $98.75

Now subtract her total from 100 to find the amount of change:

100 - 98.75 = 1.25

The change was $1.25

Answer:y=-3

Step-by-step explanation:5(y+2/5)=-13

so first you simplify both sides of the equation

(5)(y)+(5)(2/5)=-13

then you distribute

5y+2=-13

then you subtract 2 from both sides

5y+2-2=-13-2

5y=-15

then u divide both side by 5

5y=-15

5       5

y=-3
