can I get help please​

Answer:

yes because if you simplify 17/40 to a decimal it will give you 0.425 and then add the negative signs and you get -0.425 so yes they are equal

Answer:

Step-by-step explanation:

Answer:

x²+10-21=y

x²-11=y

x²=11+y

if you put value y =-11 than it can be resolve

x²=11-11

x²=0

x=0

Answer:

1) 1/2

2) 2/1

3) -1/2

4) -2/1

Step-by-step explanation:

use two ordered pairs to find slope by using this formula:

difference of y-values over difference of x-values

example:  for problem #1, I used points (0,3) and (2,4)

difference of y-values:  4-3 = 1

difference of x-values:  2-0 = 2

Slope is 1/2

Answer:

your answer is right its 90°

Answer:

-9

Step-by-step explanation:

Answer:

x = -9

Step-by-step explanation:

i dont know

i think is very dificult

ok bye

Step-by-step explanation:

Answer:

K = 2

Step-by-step explanation:

Rewriting the expression mathematically;

√(k+2)=2√(k-1)

square both sides

k+2=4(k-1)

k+2=4k-4

Collect like terms

2+4=4k-k

6=3k

Dibaide both sides by 3

3k/3 = 6/3

k = 2

the answer of

1. x= 60

2. x= 50

Answer:

Given:

In a triangle, side x has a length of 15 cm and side y has a length of 4 cm.

To find:

The possible value of side z.

Solution:

In a triangle, the sum of two smaller sides must be greater than the largest side otherwise the triangle is not possible.

Case I: Let x be the largest side, then

[tex]y+z>x[/tex]

[tex]4+z>15[/tex]

[tex]z>15-4[/tex]

[tex]z>11[/tex]               ...(i)

It is clear that [tex]y<x[/tex]. So, y cannot be a largest side.

Case II: Let z be the largest side, then

[tex]x+y>z[/tex]

[tex]15+4>z[/tex]

[tex]19>z[/tex]               ...(ii)

From (i) and (ii), we get

[tex]11<z<19[/tex]

It means the value of z lies between 11 and 19.

From the given options, only 17 is the value which lies between 11 and 19. So, the possible length of side z is 17 cm.

Therefore, the correct option is C.

Answer:

4

Step-by-step explanation:

okay since there was a 50% INCREASE, 6 is (100%+50%) greater than last months amount.

100%+50%=150%=1.5

let's say that x is last months amount

6=1.5x

x=6/1.5

x=4

There were 4 musicians in the band last month.

I really hope this helps! <3 Good luck!

Answer:

angle )) = 22°

Step-by-step explanation:

the imbedded triangle is a right triangle because the hypotenuse is the diameter.

the angle at "))" is 90 - 58 = 22°

Answer:

Step-by-step explanation:

The inscribed triangle is right as one side lies on the diameter.

The missing angle is complementary with the given:

Answer:

Acceleration is 35,9. I think so

Step-by-step explanation:

v0=12m/s

v=36m/s

t=120s

a=?

a=v–v0/t,

a=36 - [tex]\frac{12}{120}[/tex]

a=36-0,1

a=35,9

Answer:

3/5

Step-by-step explanation:

6/10 => 3/5

in decimal form its 0.6

Answer:

6÷1000=0,6

Step-by-step explanation:

6÷1000=0,006

0,6/100=

0,6%

the Correct answer is 0,6

Answer:

Your number is 102.

120/3=40 (3 numbers so divide by 3)

3+15=18

120-18=102

What would you like to know? The total surface area? The lateral surface area? The volume, perhaps? The radius?

Answer:

Cone volume 8,377.580410 cm^3

Step-by-step explanation:

Answer:

50 times

Step-by-step explanation:

Given that:

Number of spins = 400

Sample space = (1, 2, 3, 4, 5, 6, 7, 8)

Probabililtybof landing on 6 on a single spin :

Probability = required outcome / Total possible outcomes

P(landing on a six) = 1/ 8

Probability of landing on a 6 in 400 spins :

1/8 * 400 = 50 times

Answer:

If y = 2x - 5, and x = 3z, then y = 6z - 5

Answer:

cherry= 4ft

maple = 2ft

Step-by-step explanation:

5.80c + 4.20m = 31.60

when we set this equation to the side of page we see

31.60 / 6 = 5.2

if he used 6ft then we can see that 5.2 is the equation

5.8cn  + 4.2mn = 5.2

4(5.8c) + 2(4.2m) = 31.60

proves the 5.2 was a higher distribution than the 4.2  

= 4 cherry and 2 maple

Answer:

AG is the line that has been shown in the image.

I believe AG = 10

Answer:

AG = 10

Step-by-step explanation:

On each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint , then

AG = [tex]\frac{2}{3}[/tex] × AE = [tex]\frac{2}{3}[/tex] × 15 = 10

Answer:

q = 10

Step-by-step explanation:

-3(q - 7) = -9

-3q + 21 = -9

-3q = -9 - 21

q = -30/-3

q = 10.
