1) (-5) - 5
2) (-10) + 11​

Answers

Answer 1

Answer:

1) -10

2) 1

Step-by-step explanation:

1)  (-5) - 5

- Removing the brackets won't change anything since it is subtraction, so now it will be - 5-5 which is equal to -10.

-5 -5 = -10

2) (-10) + 11

- The same case applies here since it is addition.

-10 + 11 = 1

Answer 2

Answer:

1) -10

2) -1

Step-by-step explanation:

[tex]( - 5) - 5 = - 10 \\ \\ ( - 10) + 11 = - 1 \: [/tex]

The perimeter of the shape is 25.71cm
Calculate the value of the radius A take pi to be 3.142

Answers

Answer:

Step-by-step explanation:

2 [tex]\pi[/tex] r=25.71

6.284r= 25.71 (divide by 8.284 on both sides)

r=4.09cm

Answer :
Use the equation: 3.142r+2r= 25.71

Combine like terms for: 5.142r = 25.71

You will find that the radius is 5. The diameter is 10.

If you are using 3.142 to represent pi, you can check using the formula for perimeter of pi times diameter/2 for a semi circle. Don't forget to add the line segment for the rest of perimeter.

It would look like this: SemiCircle: 3.142(10)/2 = 15.71(distance around semi circle) + 10 (the line segment) = 25.71

On Sunday morning, 4 1/2 crates of grapes are delivered to thee grocery store. 2/5 of the grapes in each crates are green grapes. How many crates would it take to deliver only the green grapes?

Answers

Answer: 1 4/5 crates

Step-by-step explanation:

From the question, we are informed that 4 1/2 crates of grapes are delivered to a grocery store and that 2/5 of the grapes in each crates are green grapes.

The number of crates that it would take to deliver only the green grapes would be:

= 2/5 × 4 1/2

= 2/5 × 9/2

= 9/5

= 1 4/5 crates

convert (-5√3,0) into polar form in radians in terms of π over the interval 0≤theta<2π

Answers

Answer:

z =  5√3(cos 0 + isin0)

Step-by-step explanation:

Convert (-5√3,0) into polar form in radians in terms of π over the interval 0≤theta<2π

The rectangular form is expressed as z = -5√3 + 0i

z = √(-5√3)² + 0²

z = √(25(3))

z = √75

z = 5√3

Get the argument

theta = tan^-1 0/-5√3

theta = tan^-10

theta = 0 degrees

Hence the polar form is expressed as z = r(cos theta + i sintheta)

z =  5√3(cos 0 + isin0)

what is the measure of angle DEF.​

Answers

Answer:

DEF = 31.8

Step-by-step explanation:

A billiard ball is struck by a cue. It travels 100 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the ball approaches the rail and the path after it strikes the rail is 45 degrees. How far is the corner pocket from where the cue initially struck the ball?

Answers

Answer:

76.53 cm

Step-by-step explanation:

From the question, the triangle formed has 2 sides and an included angle ;

Angle, θ = C = 45°

We use cosine rule :

Taking the side to find as c

a = 100 ; b = 100

From cosine rule :

c = sqrt(a² + b² - 2abCosC)

c = sqrt(100² + 100² - 2(100*100)Cos45

c = sqrt(10000 + 10000 - 20000 * 0.7071067)

c = sqrt(20000 - 14142.135)

c = sqrt(5857.865)

c = 76.536690

c = 76.53 cm

Taut learns that when she spends $65.00 on supplies she is able to grow 162.5 pounds of tomatoes. How many dollars is Taut spending per pound of tomatoes grown?

Answers

Answer: $0.4 is spent by Taut  per pound of tomatoes grown

Step-by-step explanation:

Given : On spending $65.00 , tomatoes grown by Taut = 162.5 pounds

To find :  Taut expenditure per pound of tomatoes grown = ?

As it is given that :

162.5 pounds of tomatoes are grown by spending = $65.00

Thus 1 pound of tomatoes are grown by spending = [tex]\frac{65.00}{162.5}\times 1=0.4[/tex]

Thus $0.4 is spent by Taut per pound of tomatoes grown

x + 3y = 2
-x + 2y = 3
Can somebody help me?

Answers

x = -1 ; y = 1

x + 3y = 2, isolate x by subtracting 3y from both sides. Now that x is alone (because x = -3y + 2) take -3y + 2 and plug it into the second equation.

-(-3y + 2) + 2y =3 ; multiply what’s in the parenthesis by -1. It now is 3y -2 + 2y =3, add the common variables ( 3y + 2y) and you now have 5y-2=3. Move the 2 to the other side by adding it to both sides, you now have 5y=5, divide both sides by 5 and y=1.

Take any equation and plug y in for 1 to get x.

For example, (in the second equation), -x+2(1)=3, multiply 2 by 1 and you’re left with -x+2=3. Subtract 2 on both sides and you have -x=1, now divide both sides by -1 and x=-1.

You can check your work by plugging in the x and/or y values into the equations

what is 28/10 as a proper fraction​

Answers

Answer:

Step-by-step explanation:

28/10 as a proper fraction.

28/10 is an improper fraction so you have to turn it into a proper fraction.

To do this divide the numerator (top figure) by 10 (the denominator) which equals 2.8 so to put it as a proper fraction you look at the whole number in 2.8 which is the 2 and keep the number after the decimal point as a fraction over the 10.

The answer would be 2 8/10

15x^2 + 41x + 28

STEP BY STEP ANSWER PLSSS​

Answers

Answer:

(3x+4)(5x+7)

Step-by-step explanation:

15x^2 +41x+28

Factor the expression by grouping. First, the expression needs to be rewritten as 15x^2 +ax+bx+28. To find a and b, set up a system to be solved.

a+b=41

ab=15×28=420

Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 420.

1,420

2,210

3,140

4,105

5,84

6,70

7,60

10,42

12,35

14,30

15,28

20,21

Calculate the sum for each pair.

1+420=421

2+210=212

3+140=143

4+105=109

5+84=89

6+70=76

7+60=67

10+42=52

12+35=47

14+30=44

15+28=43

20+21=41

The solution is the pair that gives sum 41.

a=20

b=21

Rewrite 15x^2 +41x+28 as (15x^2 +20x)+(21x+28).

(15x^2 +20x)+(21x+28)
