Answer:

y = -3

Step-by-step explanation:

Let's solve your equation step-by-step.

5 (y+2/5) = −13

Step 1: Simplify both sides of the equation.

5(y+2/5)= −13

(5)(y) + (5)(2/5) = −13(Distribute)

5y + 2 = −13

Step 2: Subtract 2 from both sides.

5y + 2 − 2 = −13 −2

5y = −15

Step 3: Divide both sides by 5.

5y/5 = −15/5

y = −3

Answer:

y = −3

hope this helps and is right :)

Answer:

c. 56 degrees

Step-by-step explanation:

angle FEG and angle DEG add up to 180.

2x-6+3x-31=180

x=31

2(31)-6=56

The measure of angle ∠ FEG is,

∠ FEG = 56°

We have to given that,

Angles are defined as,

∠ FEG = (2x - 6)°

∠ DEG = (3x + 31)°

Here, Angles FEG and angle DEG are linear pair.

Hence, angle FEG and angle DEG add up to 180.

2x - 6 + 3x + 31 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 155 / 5

x = 31

Therefore, The measure of angle ∠ FEG is,

∠ FEG = (2x - 6)°

∠ FEG = (2 × 31 - 6)°

∠ FEG = (62 - 6)°

∠ FEG = 56°

Question: A B and C form a triangle where BAC = 90°. AB = 7.4 mm and CA = 12 mm. Find the length of BC, giving your answer rounded to 1 DP.

Answer:

14.1 mm

Step-by-step explanation:

From the diagram attached,

Using pythagoras theorem,

a² = b²+c²............... Equation 1

From the attached file,

Given: a = x, b = 7.4 mm, c = 12 mm

Substitute these values into equation 1, and solve for x

x² = 7.4²+12²

x² = 54.76+144

x² = 198.76

x = √(198.76)

x = 14.1 mm

Hence, the length of BC = 14.1 mm

Answer:

(x+4)^2 + (y+2)^2 = 5

Explanation:

Using the midpoint formula, we find that the center of the circle is (-4, -2). We also calculate using the distance formula that between the two points is [tex]\sqrt{2\\0}[/tex]or [tex]2\sqrt{5\\\\}[/tex].

Because we found the diameter, to find the radius we divide by two, getting [tex]\sqrt{5\\\\}[/tex].

Now that we have the center, (-4, -2), and the distance from the center to the radius, we can put the information into the circle equation:

(x-h)^2 + (y-k)^2 = r^2

This becomes:

(x+4)^2 + (y+2)^2 = 5

Answer:

Step-by-step explanation:

(x-(-4))^2+(y-(-2))^2=5

since 2 negatives equal a positive, - -4 = +4

same thing for -2

(x+4)^2+(y+2)^2=5

Answer:

12

Step-by-step explanation:

A sequence is given and we need to find the term when it will become -24 . The given sequence is,

9 , 6 , 3 ,0 , . . . . .

Here Common Difference can be calculated by subtracting consecutive terms . So the Common Difference is 6-9 = -3 . Here the nth term is (-24) .Now using the formula to find nth term .

⇒ T_n = a + (n-1)d

⇒ (-24) = 9 + (n-1)(-3)

⇒ -24-9 = (n-1)(-3)

⇒ (n-1) = -33/-3

⇒ n-1 = 11

⇒ n = 11 + 1

⇒ n = 12

Answer:

$576.80

Step-by-step explanation:

We have been given that Mr. Juárez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest.

We are asked to find the total amount that Mr. Juárez will have in his account at the end of 3 years.

We will use simple interest formula to solve our given problem.

[tex]A=P (1+rt)[/tex]

A = Final amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Let us convert 1% into decimal form,

1%=1/100=0.01

P=$560 and t=3

A=$560 (1+0.01(3))

A=$560 (1+0.03)

A= $560 (1.03)

A= $576.80

Therefore, Mr. Juárez will have $576. 80 in his account at the end of 3 years. Hope this helps!

Answer:

3.7

Step-by-step explanation:

each tick represents .1 unit

Answer:

x=65°  

Step-by-step explanation:

Since all exterior angles add up to 360°.

⇒(3x+25°) + (20°) + (x+55°) =360°

⇒4x+100°=360°                                      {Add up like terms}

⇒4x=260°                                                {Subtract 100 from both sides}

∴  x=65°                                                   {Isolate x (divide both sides by 4)}

Answer:

Raul made 8 servings of fruit salad

Step-by-step explanation:

Here, we want to get the number of servings made by Raul

From the question;

1 serving = 1/2 cup

x servings = 4 cups

Thus;

4 * 1 = x * 1/2

x = 4/(1/2)

x = 8 servings

Answer:

-2 = n

Step-by-step explanation:

Multiplying both sides by (5/4) quickly isolates (n - 3):

(5/4)(4/5)(n - 3) = (5/4)(n - 2), or

n - 3 = (5/4)(n - 2)

Let's eliminate fractions by multiplying both sides by 4:

4n - 12 = 5n - 10

Combining like terms, we get -2 = n

The height is 11 in

Step-by-step explanation:

I think you mean triangle?

area of a triangle is A = 1/2 b h

fill in and solve for h

22 = 1/2 4 h

44 = 4h

11 = h

Answer:

1) 24 - 40 + 34 = 18

2) 24 - 22 - 34 = -32

3) 12  + 0 -15 = -3

4) 12 + 30 -15 = 27

5) -18 + 76 -34 = 24

Step-by-step explanation:

The given equations are;

1) 24 _ 34 = 18

We have;

18 - (34 + 24) = -40

Therefore;

24 - 40 + 34 = 18

2) 24 _ - 34 = -32

We have;

-32 - (24 - 34) = -22

Therefore;

24 - 22 - 34 = -32

3) 12 _ -15 = -3

We have;

-3 - (12 - 15) = 0

Therefore;

12  + 0 -15 = -3

12 - 15 = -3

4) 12 _ -15 = 27

We have;

27 - (12 - 15) = 30

Therefore;

12 + 30 -15 = 27

5) -18 _ -34 = 24

We have;

24 - (-18 - 34) = 76

Therefore;

-18 + 76 -34 = 24.

1. 24 x 34=18

2. 24 ➗ -34=-32 (i dont have the division thing lol)

3. 12 - 15=-3

4. 12 - (-15)=27

5.  -18 x -34=24

Answer:

a

Step-by-step explanation:

The Lines are all different angles hence they are all different lengths

it's not A or D

Step-by-step explanation:

math I guessssssss

Answer:

D

Step-by-step explanation:q

If you have a 30 degree reference angle, the side opposite (the side not part of the reference angle) is 1/2 the size of the hypotenuse.

Since the side opposite is 12, the hypotenuse is easily found.

1/2 = opposite / hypotenuse

1/2 = 12 / hypotenuse                     Cross multiply

hypotenuse = 2 * 12

hypotenuse = 24

Now use the Pythagorean Theorem to get the third side.

c = 24

a = 12

b = ?

a^2 + b^2 = c^2

12^2 + b^2 = 24^2

144 + b^2 = 576                                  Subtract 144 from both sides.

b^2 = 576 - 144

b^2 = 432

Now  you have to factor 432 down to its primes

432 = 2 * 2 * 2 * 2 * 3 * 3 * 3

The rule is for every two 2s you take one outside the root sign and throw the other one away. If there are an odd number of factors, leave one of them under the root sign.

sqrt(b^2) = sqrt(432)

b = 4 * 3sqrt(sqrt(3))

b = 12 sqrt(3)

Answer

r = 12*sqrt(3)

Got it right on edge

Given:

The function is:

[tex]C(t)=10(1.029)^{24t}[/tex]

Where, C(t) is the total number of cells after t hours.

To find:

The function that is approximately equivalent to C(t).

Solution:

We have,

[tex]C(t)=10(1.029)^{24t}[/tex]

It can be rewritten as:

[tex]C(t)=10(1.029^{24})^{t}[/tex]            [tex][\because (a^m)^n=a^{mn}][/tex]

[tex]C(t)\approx 10(1.986)^{t}[/tex]         [tex][\because 1.029^{24}\approx 1.986][/tex]

The function [tex]C(t)=10(1.986)^{t}[/tex] is approximately equivalent to C(t).

Therefore, the correct option is 3.

Answer:

x=-2, y= 1

Step-by-step explanation:

Given data

-2x+3y= 7 --------------1

5x+8y= -2--------------2

Multiply 1 by 5 and 2 by 2 and add

-2x+3y= 7   X 5

5x+8y= -2   X 2

-10x+15y= 35  

10x+16y= -4  

0x+31y= 31

31y= 31

y= 31/31

y= 1

put y= 1 in eqn 1

-2x+3y= 7

-2x+3(1)= 7

-2x+3=7

-2x= 7-3

-2x= 4

x=- 4/2

x= -2

Answer:

That would be impossible because you would get melted by the earth core

Step-by-step explanation:

When you say bottom of the world, I'm assuming you mean the middle or the core. Like the other answer said, I'd just die. BUT if I didn't die, then yes, I think I'd be in all the time zones. :) Or I just wouldn't have a sense of time.

We tell time based on how much sunlight we get, so would that mean it would be midnight forever?
