Step-by-step explanation:

413 is the same as a number decreased by 11 because when you say 11 is decreased by a number that means we are subtracting a number from 11 but when you say a number is decreased by 11 it means 11 is being subtracted from a certain number to give 413

» From the trigonometric identities:

[tex]{ \tt{ \sin {}^{2} \theta + \cos {}^{2} \theta = 1 }}[/tex]

» Substitute to the formular:

[tex]{ \tt {( \frac{ \sqrt{7} }{4} )}^{2} + { \cos }^{2} \theta = 1 } \\ \\ { \tt{ \frac{7}{16} + { \cos}^{2} \theta = 1 }} \\ \\ { \tt{ \cos {}^{2} \theta = 1 - \frac{7}{16} }} \\ \\ { \tt{( \cos\theta) {}^{2} = \frac{9}{16} }} \\ \\ { \tt{ \sqrt{ {( \cos \theta}^{2}) } = \sqrt{( \frac{9}{16}) } }} \\ \\ { \tt{ \cos \theta = \frac{ \sqrt{9} }{ \sqrt{16} } }} \\ \\ { \boxed{ \tt{ \cos \theta = \frac{3}{4} }}}[/tex]

Ratio compares two quantities. The amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.

Given to us

The solubility of calcium carbonate is 14.

We know that to dissolve 14 milligrams of calcium carbonate we will need 1 liter of water. therefore, the ratio of water and calcium carbonate can be written as,

[tex]\rm \dfrac{calcium\ carbonate}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]

We need to find the amount of water needed to dissolve 14 grams of water, therefore, we will convert grams to milligrams,

1 gram = 1000 milligram

14 gram = 14,000 milligram

Using the same ratio,

[tex]\rm \dfrac{14,000\ milligram}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]

[tex]\rm {water} = \dfrac{14000\ milligram \times 1\ liter}{14\ milligram}[/tex]

water = 1000 liters

Hence, the amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.

Answer:

Aviva deposited $4,000

Step-by-step explanation:

Given:

Solving:

We'll create an equation to find the amount of money Aviva deposited.

D = 240(50/3)

D = the amount of money she has deposited.

50/3 represents 94% of D.
Since 240 is 6% of the deposit Aviva has deposited, multiplying 50/3 by 240 will equal 100% of D.

Solve:

4,000 = 240(50/3)

The amount of money Aviva deposited is $4,000.

*This is one method to solve.

(a) 60° (b) 125°

Step-by-step explanation:-

Given are three [tex]x[/tex]'s, so,

[tex]3x = 180[/tex](As all sides of triangle add upto 180°)

[tex] = > x = \frac{180}{3} [/tex]

[tex] = > x = 60[/tex]

Hence, value of x is 60°

Given two interior angles(55°,70°) & one exterior angle([tex]x[/tex]°)

[tex] = > x° = (55 + 70)°[/tex]

[tex] = > x° = 125°[/tex]

Hence, value of x is 125°

Answer:

$180

Step-by-step explanation:

  Simple interest → ( principal * rate of interest * time in years ) ÷ 100

Here the principal is $3,000, rate of interest is 12%, years in years will be

(6/12) = 0.5 years

Using the formula:

Interest charge →  ( 3,000 * 12  * 0.5 ) ÷ 100

                          → ( 18000 ) ÷ 100

                          → $180

Answer:

the zeroes are -2 and 8

Step-by-step explanation:

Therefore, the zeroes are -2 and 8

Velocity can be represented in horizontal and vertical components

The horizontal component form of the velocity is 12.5 mph

The given parameters are:

Velocity = 25 mph

Angle = 60 degrees

The horizontal component form of the velocity is then calculated as:

[tex]v_x = 25 * \cos(60)[/tex]

Evaluate the product

[tex]v_x = 12.5[/tex]

Hence, the horizontal component form of the velocity is 12.5 mph

Answer:

11700 m²

Step-by-step explanation:

Split the shape in two. One rectangle 150x30 and one triangle 180x80.

Find the areas of both and add them:

A = bh + 1/2bh

A = 150(30) + 1/2(180)(80)

A = 4500 + 7200

A = 11700

Answer:

-84

Step-by-step explanation:

Let the number be x. Then we have,

[tex]\frac{x}{-7}[/tex] (the quotient of a number and -7)

[tex]\frac{x}{-7}-2[/tex] (decreased by 2)

[tex]\frac{x}{-7}-2=10[/tex] (is 10)

Now we can solve for x,:

[tex]\frac{x}{-7}-2=10[/tex]

[tex]\frac{x}{-7}=12[/tex]

[tex]x=-84[/tex]

So, the original number is -84

Answer:

-84

Step-by-step explanation:

[tex]\frac{n}{-7}[/tex] -2 = 10

add 2 to each side to get:

[tex]\frac{n}{-7}[/tex] = 12

multiply each side by -7 to get:

n = -84

Translation along x axis is ~

[tex]\qquad \sf  \dashrightarrow \:1 + 3[/tex]

[tex]\qquad \sf  \dashrightarrow \:4 \: \: units \: \: towards \: \: left[/tex]

Translation along y axis ~

[tex]\qquad \sf  \dashrightarrow \: - 8 + 13[/tex]

[tex]\qquad \sf  \dashrightarrow \:5 \: \: units \: \: towards \: \: down[/tex]

So, same goes with translation of (-5 , 9)

[tex]\qquad \sf  \dashrightarrow \: x \: \:coordinate = - 5 - 4 = - 9[/tex]

[tex]\qquad \sf  \dashrightarrow \: y \: \:coordinate = 9 - 5 = 4[/tex]
