Answer:

Step-by-step explanation:

Percentage of 30% of 370 = ?

30% of 370 is equivalent to multiplying them: 30% × 370.

= 30/100 x 370

= 111

Answer:

Late but its 115

5555555555555555555555555555555

Answer:

Maybe 6000ft but im not completely positive

Step-by-step explanation:

Answer:

The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. [tex]\frac{65}{4} = \frac{13}{2}[/tex]

They are not equal.

For 65/4 you cannot divide it by 2 and then get 13/2. You would get 32.5/2.

32.5/2 is not equal to 13/2

Answer:

Y= -2x+3

Step-by-step explanation:

the point (0,3) is where the y intercept is (since x is 0 and y is 3) and the -2 is the slope (or -2/1, it's still the same thing though).

Hoped this helped!

Answer:

-6/7, the first one

Answer:

[tex]\boxed {m = -\frac{6}{7}}[/tex]

Step-by-step explanation:

Use the Slope Formula to help determine the slope of the two following points:

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following points to the formula:

[tex](x_{1}, y_{1}) = (-3, 5)[/tex]

[tex](x_{2}, y_{2}) = (4, -1)[/tex]

[tex]m = \frac{-1 - 5}{4 + 3}[/tex]

-Solve for the slope:

[tex]m = \frac{-1 - 5}{4 + 3}[/tex]

[tex]m = \frac{-6}{7}[/tex]

[tex]\boxed {m = -\frac{6}{7}}[/tex]

Therefore, the slope is [tex]-\frac{6}{7}[/tex].

Answer:

Step-by-step explanation:

Step-by-step explanation:

we know ,

area of circle =πr^2

hence we get from the figure that the diameter of circle is 19 cm and we can find radius

r=d/2

r=18/2=9cm

area of semicircle =πr^2/2

area of Semi circle equals to =22*(9)^2/7/2

=127.2857143

Answer:

Today: Sunday, 11 October 2020

Hour: 23.05 WIB (Indonesian)

_________________________

D = 18

r = 18 ÷ 2 = 9

area of semicircle = πr²/2

area of semicircle = 3.142 . 9²/2

area of semicircle = 3.142 . 81/2

area of semicircle = 254.502/2

area of semicircle = 127.251 cm²

Answer:

Hi there!

Your answer is:

Y= 0

X= 9

Step-by-step explanation:

3x=27+3y

3x-10y=27

Solve one of them for Y

I chose the first equation

3x=27+3y

-27

3x-27=3y

/3

x-9 = y

NOW, plug y in the second equation!

3x-10y=27

y= x-9

3x-10y=27

3x-10(x-9) = 27

Solve for x!

3x-10x+90 = 27

-7x + 90 =27

-90

-7x = -63

/-7

x= 9

FINALLY, plug back in x for y equation

y=x-9

x=9

y=9-9

y=0

4. -10 1/4

Step-by-step explanation:

Answer:

Step-by-step explanation:

a

The square root of 20 = 4.47 so a for sure.

But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list

Now what to do about - 8

(- 8)^2 = 64

The square root of 64 = +/- 8

It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.

I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.

a for sure.

b and c I think so.

-8 is iffy.

Answer:

2. z = 1 - 2·i    →    √5

3. z = 4 + 3·i   →      54

4. z = 6 - 8·i    →     10

1. z = √5 - i      →    √6

Step-by-step explanation:

1. z = √5 - i

The distance from the origin = √((√5)² +1²) = √(5 + (-1)²) = √6

Therefore, z = √5 - i → √6

2) z = 1 - 2·i

The distance from the origin = √(1² + (-2)²) = √5

Therefore, z = 1 - 2·i → √5

3) z = 4 + 3·i

The distance from the origin = √(4²+3²)) = √(16 + 9) = √25 = 5

Therefore, z = 4 + 3·i → 5

4) z = 6 - 8·i

The distance from the origin = √(6²+8²)) = √(36 + 64) = √100= 10

Therefore,  z = 6 - 8·i →  10

Answer:

[tex]-5*2[/tex] is larger.

Step-by-step explanation:

[tex]-5*2=-10[/tex]

[tex]-14+1=-13[/tex]

[tex]-10>-13[/tex]

-10 is greater because both numbers are negative, so -10 is the higher number.

Answer:

5 x 2 is the larger than -14 + 1.

Step-by-step explanation: -5 x 2 = -10, and -14 + 1 = -13. Plz tell me if you got it right.

Answer:

x= 44

Step-by-step explanation:

Add 82+54.

Subtract 136 from 180. Giving you your answer.

Always subtract from 180 since a triangle is always 180.

Can you mark me brainliest? And 5 star?

Answer:

x= 44

Step-by-step explanation:

180 = 82 + 54 + x

180 = 136 + x

180 - 136 = 136 -136 + x

44 = x

Answer:

81 is the perfect square of the first option

Step-by-step explanation:

It is asking for the perfect square so the third option will be eliminated because that is cubed.

The fourth option will also be eliminated because it is multiplication.

The second option will be eliminated because it has addition.

81 is the perfect square of the first option

x = -3    x = -2

answer:

72

step-by-step explanation:

your question doesn't make mathematical sense how can 12 = 6 then subract 90?

maybe you meant 12 + 6 - 90

if so

the answer is

72

(my work)

12 + 6 = 18

18 - 90 = 72

Answer:

Step-by-step explanation:

step one:

let the number of Blu-rays  be b and

DVDS be d,

step two:

given that Blu-rays cost $25.99each and

DVDS cost $15.99 each,

we can model the cost of the Blu-rays and DVDS, as

100=25.99b+15.99d

hence the expression for the number of Blu-rays and DVDS, is given as

100=25.99b+15.99d

Answer: D

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

d) x = 4/3

Step-by-step explanation:

Given equation,

→ -x + (3/7) = 2x - (25/7)

Now the value of x will be,

→ -x + (3/7) = 2x - (25/7)

→ -x - 2x = -(25/7) - (3/7)

→ -3x = -28/7

→ -3x = -4

→ x = -4/-3

→ [ x = 4/3 ]

Hence, the value of x is 4/3.
