Answer:

Look below.

Step-by-step explanation:

Not exactly sure what is being asked here, but I'm going to assume you need to convert them into decimals.

7.) 0.51

8.) 3.95

9.) 0.49

10.) 0.11

11.) 0.39

12.) 7.39

13.) 9.70

14.) 2.56

15.) 2.77

16.) 0.37

17.) 0.04

18.) 7.73

19.) 0.14

20.) 2.19

Any percent that goes over 100, goes into the unit place.

If I didn't answer the question right, then let me know.

√6= 2.45    6+2.45=8.45  8.45 and 2/3 =9.12  

answer to question 3 is 6+ √6

The fourth one idk if im right or not but im pretty sure its x³ - 12x² + 37x = 0

Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeroes in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients.

Answer:

A. & E.

Step-by-step explanation:

A.) 4-4=0

B.) 4+4=8

C.) 1-2=-1

D.) 25-10=15

E.) 16+8=24

Step-by-step explanation:

100/2[500/5{6+(21-17)}]

using BODMAS

100/2[500/5{6+4}]

100/2[500/5 × 10]

100/2 [100 × 10]

100/2 × 1000

50× 1000

50000

I think this is the answer. I'm not really sure but this is how I studied

All the best!

Answer: y=-4x-31

Step-by-step explanation:

To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.

-7=-4(-6)+b            [multiply]

-7=24+b                 [subtract both sides by 24]

b=-31

Now, we know that y=-4x-31 is the equation.

Answer:8% this is the answer

Answer:

- (x - 4)(x - 11)

Step-by-step explanation:

Given

- x² + 15x - 44 ← factor out - 1 from each term

= - 1 (x² - 15x + 44) ← factor the quadratic

Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)

The factors are - 4 and - 11 , since

- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus

x² - 15x + 44 = (x - 4)(x - 11) and

- x² + 15x - 44 = - (x - 4)(x - 11)

Answer:

C

Step-by-step explanation:

The similarity statement is correct. Because they are similar, AB is equal to EF, so to find x, you do x-2=2.2. Solve that and you get x=0.2

Answer:

the answer is x = 2

Step-by-step explanation:

2x+2=4+1x

(2x-1x)+2= 4 +(1x-1x)

1x+2=4

1x(2-2)=(4-2

1x=2

2/1=x

x=2

Answer: X=2

I might be wrong

Answer:

1) = 180 degree reason = being AB is a straight line or supplementary

2) = angle AOB reason = being all the angles are of a straight line AB

3) = x + 2x+34 + 20 = 180 degree. reason being supplementary angle

4) = 42 degree

1) fill 180° in the blank

Reason :

Because AOB angles is half a page so it equals 180°

_________________________________

2)fill 180° in the blank

Reason :

AOE + EOF + FOB = AOB

And we have found that AOB angles is half a page so it equals 180°

_________________________________

3) 2x + 34 _ 180°

_________________________________

4) x = 42°

Answer:

2.25 miles

Step-by-step explanation:

If she can walk 3/4 of a mile in 20 minutes you need to multiply 3/4 by 3 because 20 times 3 is 60 and there is 60 minutes in a hour

Answer:

n=3

Step-by-step explanation:

Answer:

if -5n+7<57, then n>-10.

if 6n+2<8, then n<1.

Step-by-step explanation:

-5n+7<57

1. subtract 7 from both sides:

-5n+7 -7< 57 -7

-5n<50

2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):

-5n ÷-5<50 ÷-5

n>-10

6n+2<8

1. subtract 2 from both sides:

6n+2 -2<8 -2

6n<6

2. divide both sides by 6:

6n ÷6<6 ÷6

n<1

Answer:

KPL= 64 degrees JPL= 116 degrees

Step-by-step explanation:

2x+24+4x+36=180

combine like terms

6x+60=180

6x=120

x=20

2(20)+24=64

4(20)+36=116

A pentagonal prism is a prism having two pentagonal bases and five rectangular sides. It is a heptahedron.

The regular right pentagonal prism is uniform polyhedron . Its dual polyhedron is the pentagonal dipyramid.

The surface area and volume for the right regular pentagonal prism of unit edge length are

S = 5+1/2sqrt(5(5+2sqrt(5)))
