The ratio given:

Toni receives $160, which is 5 portions.

Each portion is:

Shai gets:

Mara receives:

Step-by-step explanation:

It is given

4x+3y=24

We can also write it as

3y=24−4x

 y=324−4x

Substituting x=0 in the given equation

 y=324−4(0)

 So we get 

 y=324

 By division 

 y=8 

 Substituting x=3 in the given equation 

 y=324−4(3)

 So we get

 y=312

 BY division 

 y=4

Answer:

36 - [18 - {14 - (15 - 4 ÷ 2 × 2)}]= 36-[18-{14-(15-4)}]= 36-[18-{14-9}]=36-[18-5]=36-13=23

Step-by-step explanation:

36 - [18 - {14 - (15 - 4 ÷2 ×2)}]

= 36 - [18 - {14 - (15 - 2 ×2)}]

= 36 - [18 - {14 - (15 - 4)}]

= 36 - [18 - {14 - 11}]

= 36 - [18 - 3]

= 36 - 15

= 21

Answer:

Step-by-step explanation:

the answer is (4 x 4)+2

Answer:

o (4+2) x4   is the expression that means 4 batches of 4+2 teaspoons of vanilla.

Step-by-step explanation:

1c = t(4 + 2) is created as t = tspoon but any letter cna represent and maybe the o means teaspoons so lets compare

we see the brackets on (4+2) x4 and use this. And if you must put a 0 in front then I would also convert to show without 0 and show both

As long as brackets separate the (4x 2) to the 4 batches it becomes a workable expression.

When algebra becomes understandable for multiplying we show 4(4 +2)

because in brackets its always add or subtract, but we recognise mainly as the question is worked out first for one part being  1 cupcake = 1c

so 1c = 4t+2t

then;  4c = 4t+2t

we need to multiply the set as a reverse to usual equations that try to make you find what t or c means.

so as we are not subtracting the numbers either side of the = we can just demonstrate a multiplication

4( 4+2)t = 0(4+2) x 4

equation in bold = expression given and chosen

they both mean the same so we know the first one in bold is an equation and the 2nd one as asked is an expression

Answer:

Step-by-step explanation:

Given

5y + 4 = 10 ( subtract 4 from both sides )

5y = 10 - 4 , that is

5y = 6

Thus 5y + 4 = 10 is equivalent to 5y = 6

Answer:

y=-5/4x+1

Step-by-step explanation:

y- y-coordinate= slope(x- x-coordinate)

y- (-4)= -5/4 (x - 4)

y - (-4)= -5/4x +5

move (-4) to the other side of the equal sign, the sign changes to +4

y= -5/4x +5 +4

y=-5/4x+1

Answer:

Slope: 2/3

Step-by-step explanation:

Take the first point (2,1) as (x1, y1), and,

the second point (5,3) as (x2, y2).

Using the slope formula to calculate the slope:

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

= (3-1)/(5-2)

= 2/3

Hence, the slope is 2/3

Answer:

B = 3.31662479

rounded to 3.32

Step-by-step explanation:

Pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]

A & B = the base and height

C = The diagonal line.

A & B can be base or height. ( base = 2 Height = 3. It can be [tex]2^{2} + 3^{2}[/tex] or [tex]3^{2} + 2^{2}[/tex] )

Because when you add it doesn't matter where each number is put.

I like doing b for the base, because there's a b in base, to make it easier for me. But you can do whatever.

A = 5

B = ?

C = 6

[tex]5^{2} + b^{2} + 6^{2}[/tex]

From here you will solve to get b.

[tex]5*5 + b^{2} = 6 * 6[/tex]

[tex]25 + b^{2} = 36[/tex]

25 - 25 + [tex]b^{2}[/tex] = 36 - 25

[tex]b^{2}[/tex] = 11

To under the exponent you have to [tex]\sqrt[/tex] it.

[tex]\sqrt{b_{2}}[/tex] = [tex]\sqrt{11}[/tex]

[tex]5^{2} + 3.32^{2} = 6^{2}[/tex]

B = 3.31662479

rounded to 3.32

Check your work :

[tex]5^{2} + 3.32^{2} = 6^{2}[/tex]

Answer:

First find x

70-x=4x

-x-4x=-70

-5x=-70

x=14

Angle BEC = 70°-x

=70-14

=56°

Angle AEB = 180- 56

= 124°

Angle DEA =4x

= 4× 14

= 56°

Angle CED = 180-56

=124°

Step-by-step explanation:

Answer:

ln (1 + sin^2(x)) + C

Step-by-step explanation:

Note that sin(2x) = 2 sin(x) cos(x).

So, the integrand is rewritten as:

(2 sin(x) cos(x)) / (1 + sin^2(x) ).

Now, make the substitution u = sin(x), so that du = cos(x) dx.  Thus, in terms of the variable u, the integrand is

(2 u )/(1 + u^2).

Make another substitution v = 1 + u^2, so that dv = 2 u du, and the integrand in terms of v is

1 / v

Now, we integrate, and then back substitute to write that the indefinite integral is

ln |v| + C = ln |1 + u^2| + C = ln |1 + sin^2(x)| + C + ln (1 + sin^2(x)) +C, since 1 + sin^2(x) + 1 is positive for all real x.

Step-by-step explanation:

[tex]\large\underline{\sf{Solution-}}[/tex]

We have to evaluate the given integral.

[tex] \displaystyle \rm = \int \dfrac{ \sin(2x) }{1 + \sin^{2} (x) } \: dx[/tex]

[tex] \displaystyle \rm = \int \dfrac{2 \sin(x) \cos(x) }{1 + \sin^{2} (x) } \: dx[/tex]

Now let us assume that:

[tex] \rm \longmapsto u = 1 + { \sin}^{2}(x)[/tex]

[tex] \rm \longmapsto \dfrac{du}{dx} = 2 \sin(x) \cos(x) [/tex]

[tex] \rm \longmapsto dx = \dfrac{1}{2 \sin(x) \cos(x) } \: du[/tex]

Therefore, the integral becomes:

[tex] \displaystyle \rm = \int \dfrac{1}{u} \: du[/tex]

[tex] \displaystyle \rm = \ln(u) + C[/tex]

[tex] \displaystyle \rm = \ln(1 + sin^{2}x ) + C[/tex]

Therefore:

[tex] \displaystyle \rm \longmapsto \int \dfrac{ \sin(2x) }{1 + \sin^{2} (x) } \: dx = \ln(1 + sin^{2}x ) + C[/tex]

Answer:

s(t)=200(1/2)^t/13

Step-by-step explanation:

Here's answer:

https://www.nysedregents.org/algebratwo/619/algtwo62019-mrs.pdf

The number of years it will take for  1/10 of this substance to remain is; 50 years

The half life formula is;

N(t) = N₀(¹/₂)^(t/t_1/2)

where;

N(t) is quantity of the substance remaining

N₀ is initial amount of substance

t is time elapsed

t_1/2 is half life

Thus;

S(t) = 200(¹/₂)^(t/15)

We want to find the time it will take 1/10 of the substance to remain. Thus;

1/10 = (200/200)(¹/₂)^(t/15)

1/10 = (¹/₂)^(t/15)

t/15 = In(1/10)/In(¹/₂)

t/15 = 3.32193

t = 49.88 ≈ 50 years
