Plz help me, I am terrible in math

Answer:

Juan's Plan

y = .25x+12.95

where y is cost and x is minutes

Tiffany's Plan

y = .15x+14.95

where y is cost and x is minutes

...

Set the cost equal and find where x is the same for both.

.25x+12.95 = .15x+14.95

Group x variables to one side of the equation

.25x + 12.95 - 12.95 - .15x = .15x - .15x + 14.95 - 12.95

.25x - .15x = 14.95 - 12.95

.1x = 2

x=20 minutes

Answer:

Kindly check explanation

Step-by-step explanation:

Given the equations :

6.01 × □ = 601 No 0.305 × □ = 305 No 0.54 × □ = 540 No 0.097 × □ = 970 Yes

Will the number 103 will make each true?

601 / 6.01= 100 (No, not true)

305 / 0.305 = 1000 (No, not true)

540 / 0.54 = 100 (No, not true)

970 / 0.097 = 10000 (No, not true)

Hence, multiplying each of the equation above by 103 will not make any of the equations true.

Given :

The cost of 5 pounds of boudin is $26.

To Find :

The constant of proportionality that relates the cost in dollars y, to the number of pounds of boudin x .

Solution :

Price per boudin in terms of x and y is :

[tex]P=\dfrac{y}{x}[/tex]

Price per boudin by given data :

[tex]P=\dfrac{26}{5}[/tex]

So,

[tex]\dfrac{y}{x}=\dfrac{26}{5}\\\\y = \dfrac{26}{5}x[/tex]

Therefore, the constant of proportionality is [tex]\dfrac{26}{5}[/tex].

Hence, this is the required solution.

Answer:

If angle a and b are complementary angles, and angle a is 64, complementary equals 90, so 90-64= 26 degrees for angle b.

Angles ∠a and ∠b are complementary angles. Then the measure of the angle ∠b will be 64°.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

The measure of the angle ∠a is 64°. And angles ∠a and ∠b are the complementary angles. Then the equation is given  as,

∠a + ∠b = 90°

64° + ∠b = 90°

∠b = 26°

The measure of the angle ∠b will be 64°.

Answer:

-1 or f =   1.333333333 + 0.3333333333x

is what i got  its not an answer so im sorry

Step-by-step explanation:

Simplifying

f(6) = 2x + 8

Reorder the terms for easier multiplication:

6f = 2x + 8

Reorder the terms:

6f = 8 + 2x

Solving

6f = 8 + 2x

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by '6'.

f = 1.333333333 + 0.3333333333x

Simplifying

f = 1.333333333 + 0.3333333333x

Answer:

The measure of the fourth angle is 90°.

Step-by-step explanation:

Let x be the measure of the fourth angle.

Given measures of the other angles : 50°,120° & 100°.

Knowledge Required :

The sum of all the interior angles of a quadrilateral is 360°.

Then,

50°+120°+100°+x=360°

⇒x = 360°-270°

⇒x = 90°

.°. x = 90°

Hence, the measure of the fourth angle is 90°.

Step-by-step explanation:

Answer:

The intersection point of the two curves is [tex](x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)[/tex].

Step-by-step explanation:

From statement we get the following equations:

Supply curve

[tex]90\cdot x - y = -50[/tex] (1)

Demand curve

[tex]10\cdot x + y = 200[/tex] (2)

Where:

[tex]x[/tex] - Quantity, measured in thousands of metric tons.

[tex]y[/tex] - Price, measured in US dollars per metric tons.

If we add both equations, then we find that quantity is:

[tex](90\cdot x -y )+(10\cdot x +y) = -50+200[/tex]

[tex]100\cdot x = 150[/tex]

[tex]x = \frac{3}{2}\,kton.m[/tex]

Then, we finally find the price by substituting on (2):

[tex]y = 200-10\cdot \left(\frac{3}{2} \right)[/tex]

[tex]y = 200-15[/tex]

[tex]y = 185\,USD[/tex]

The intersection point of the two curves is [tex](x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)[/tex].

Answer:

A. 904.3 cm³

Step-by-step explanation:

Radius of the ice cream cone (r) = 6 cm

Height of the ice cream cone (h) = 12 cm

Radius of the shape of hemisphere formed by the half scope of ice cream = 6 cm

Total volume of ice cream = volume of cone + volume of hemisphere

= [tex] (\frac{1}{3} \pi r^2 h) + (\frac{2}{3} \pi r^3) [/tex]

Plug in the values

[tex] (\frac{1}{3} \times 3.14 \times 6^2 \times 12) + (\frac{2}{3} \times 3.14 \times 6^3) [/tex]

[tex] (\frac{1}{3} \times 3.14 \times 36 \times 12) + (\frac{2}{3} \times 3.14 \times 216) [/tex]

[tex] = (1 \times 3.14 \times 12 \times 12) + (2 \times 3.14 \times 72) [/tex]

[tex] = (452.16) + (452.16) [/tex]

Total volume of ice cream = 904.3 cm³ (nearest tenth)

Answer:

The temperature six minutes after being turned on is 125°.

T(t)= 65° + t * 10°

Step-by-step explanation:

Linear Equations

Ellie sets the temperature of the oven to 65°. The oven will increase the temperature at 10° per minute after being turned on.

After the first minute, the temperature of the oven is

65° + 10° = 75°

After the second minute, the temperature is:

65° + 2*10° = 65° + 20° = 85°

The same pattern goes on after minute 6, where the temperature is:

65° + 6*10° = 65° + 60° = 125°

The temperature six minutes after being turned on is 125°.

The general formula can be deducted for any time t as:

T(t)= 65° + t * 10°

Answer:

$375.71

Step-by-step explanation:

Given that:

Rate of interest = 5.5% compounded quarterly

Time = 1.5 years

Principal amount deposited in savings account = 1.5 years

To find:

Interest earned = ?

Solution:

Formula for amount with interest compounding quarterly:

[tex]A = P(1+\dfrac{r}{4\times 100})^{4t}[/tex]

Putting the values:

[tex]A = 4400(1+\dfrac{5.5}{4\times 100})^{4\times 1.5}\\\Rightarrow 4400\times 1.01375^6\\\Rightarrow 4400\times 1.085\\\Rightarrow \$ \bold{4775.71}[/tex]

Interest earned = Amount - Principal

Interest earned = 4775.70 - 4400 = $375.71

2 + x = 3 (2)

x = 6 - 2

x = 4

The triangle ΔABC is similar to the triangle ΔADE. Then the value of the variable 'x' will be 4 units.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The triangle ΔABC is similar to the triangle ΔADE. Then the ratio of the corresponding sides will be constant. Then the equation is given as,

2 / (2 + x) = 1 / 3

Simplify the equation, then we have

2 / (x + 2) = 1 / 3

6 = (x + 2)

x = 6 - 2

x = 4

The value of the variable 'x' will be 4 units.
