Answer:

in about 27 days

Step-by-step explanation:

i assumed 30 days per month when i set up this equation:

w = words learned daily

100 + 4w = 180 + 30/30w

100 + 4w = 180 + w

3w = 80

w = 26 2/3

Answer:

3.86 weeks/three weeks

Step-by-step explanation:

x time it takes for thier vocab to be the same in days

so the boy lerns 360 words of spanish in a year

or 360/365 words of spanish per day which is 72/73 words per day

so,

100+4x=180+72x/73

80=288x/73-72x/73

80=216x/73

80*73=5,840

5,840=216x

27.037 days=x

so now we have to divide by seven to get weeks so that is 3.86 weeks.

so some time in week three

Answer:

75.8°

Step-by-step explanation:

x + x + 28.4° = 180°{ being linear pair }

2x = 180° - 28.4°

2x = 151.6°

x = 75. 8°

Hope it will help :)

Answer:

83.96 (approximately)

Step-by-step explanation:

I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.

It should look like:

[tex]cos^{-1}(\frac{4}{38})[/tex], which is approximately 83.96.

Hopefully this is right, if not, please let me know. Good luck.

Answer:

15,600 Gallons

Step-by-step explanation:

The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Last used of water = 12000

30% of 12000 = (30/100)12000 = 3600

Water used in the current year = 12000 + 3600 = 15600 gallons.

Hence "The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water".

Answer:

The correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.

Step-by-step explanation:

The area (A) of each pizza is given by:

[tex] A = \pi r^{2} [/tex]

Where:

r: is the radius

For the 12-inch pizza we have:

[tex] A_{12} = \pi (\frac{12 inch}{2})^{2} = 113.1 inch [/tex]

And for the 6-inch pizza we have:

[tex] A_{6} = \pi (\frac{6 inch}{2})^{2} = 28.3 inch [/tex]

The ratio between A₆ and A₁₂ is:

[tex] \frac{A_{6}}{A_{12}} = \frac{28.3 inch}{113.1 inch} = 0.25 = \frac{1}{4} [/tex]

Hence:

[tex] A_{6} = \frac{A_{12}}{4} [/tex]

Therefore, the correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.

I hope it helps you!            

The area of the 6-inch pizza is 1/4 the area of the 12-inch pizza

Diameter of pizza A = 12 inch

Diameter of pizza B = 6 inch

Ration of Area of Pizza A to B = [πr1²] / [πr2²]

Ration of Area of Pizza A to B = [(12/2)²] / [(6/2)²]

Ration of Area of Pizza A to B = [(6)²] / [(3)²]

Ration of Area of Pizza A to B = 36 / 9

Ration of Area of Pizza A to B = 4:1

So,

Option "C" is the correct answer of the following question.

Answer:

1a. x=2 1b. x= -1

Step-by-step explanation:

In ∆ABC,

As, we have :

So, By angle sum property of triangle :

∠A + ∠B + ∠C = 180°

[tex] \tt : \implies 60\degree + 60\degree + \angle C = 180\degree[/tex]

[tex] \tt : \implies 120\degree + \angle C = 180\degree[/tex]

[tex] \tt : \implies \angle C = 180\degree - 120\degree[/tex]

[tex] \tt : \implies \angle C = 60\degree[/tex]

Now, we have :

As, all angles are of same length, therefore it is a equilateral triangle.

We know that sides of equilateral triangle are equal.

[tex] \tt : \implies AB = BC = AC[/tex]

Now, we have BC = 12 units.

Hence, all sides are of 12 units.

Now, we know that area of equilateral triangle is :

[tex] \large \underline{\boxed{\bf{Area_{(equilateral \: triangle)} = \dfrac{\sqrt{3}}{4} side^{2}}}}[/tex]

[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{4} \times (12 \: units)^{2}[/tex]

[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{\cancel{4}} \times \cancel{144} \: units^{2}[/tex]

[tex] \tt : \implies Area = \sqrt{3} \times 36 \: units^{2}[/tex]

[tex] \tt : \implies Area = 36\sqrt{3} units^{2}[/tex]

So, Area of given triangle is 36√3 units².

Answer:

y = - [tex]\frac{1}{4}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

2x + 8y = 24 ( subtract 2x from both sides )

8y = - 2x + 24 ( divide all terms by 8 )

y = - [tex]\frac{1}{4}[/tex] x + 3 ← in slope- intercept form

Answer:

60 cm ( squared )

Step-by-step explanation:

you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).
