Answer:

One senior citizen ticket costs 4 dollars and one child ticket costs 7 dollars

Step-by-step explanation:

Let x be the cost of a senior ticket and y be the cost of a child ticket then...

3x+9y=75

8x+5y=67

We can simplify the first equation by dividing everything by 3...

x+3y=25

Now, isolate x by subtracting 3y from both sides

x=25-3y

We can solve this system of equations using substitution (substitute 25-3y for x)...

8(25-3y)+5y=67

200-24y+5y=67

Combine like terms

-19y+200=67

Subtract 200 from both sides

-19y=-133

Divide both sides by -19

y=7

Plug 7 back in for y to solve for x

x=25-3(7)=25-21=4

One senior citizens ticket costs 4 dollars and one child ticket costs 7 dollars.

Answer:

x = 35°

Step-by-step explanation:

The three angles in a triangle add up to 180°.

The little square in the corner of one angle means that is a right angle and is 90°.

90° + 55° + x = 180°

145° + x = 180°

Subtract 145° from both sides.

x = 180° - 145°

x = 35°

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:

Congruent triangles have congruent corresponding sides and angles, while similar triangles may or may not be congruent

The congruence statement is given as:

ΔPOG ≅ ΔSOR

The above means that:

Points P, O and G correspond to the points S, O and R

Hence, the corresponding side of PO in ΔPOG ≅ ΔSOR is SO

The congruence statement is given as:

ΔPOG ≅ ΔSOR

Hence, the congruent triangles are ΔPOG ≅ ΔROS

In figure 2, we have:

2 congruent sides, and 1 congruent angle between the congruent sides

Hence, the congruence postulate is SAS

The congruence statement is given as:

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:

4 and 5

Step-by-step explanation:

The total percent of decrease in price of the shares of Selena's stock which Selena first buys and then sold is 11.5 percent.

Percentage decrease in a number is the ratio of total decrease in the original value of a number to the decreased value in the percentage form.

Given information-

The total stock buy by the Selena in $32.

The total stock sold by the Selena in $28.32.

As the total stock buy by the Selena in $32, and the total stock sold by the Selena in $28.32. Thus the total decrease in the price of stock is,

[tex]C_s=32-28.32\\C_s=3.68[/tex]

Thus the total decrease in the price of stock is $3.68.

As the cost price of the stock is $32 and the total decrease in the price of stock is $3.68. Thus the total percent of decrease in the price of the stock is,

[tex]\Delta C_s=\dfrac{3.68}{32}\times100\\\Delta C_s=11.5[/tex]

Thus the total percent of decrease in the price of the stock is 11.5 percent.

Given :

To Find :

Solution :-

Let us take that ,

→ number of flags sold = f

→ number of pennant sold = p

Money earned by selling flags

→ Money = $6 * f = $6f

Money earned by selling pennants

→ Money = $1*p = $1p

Total money earned

→ Total Money = $6f + $1p

Total items sold

→ Total items = f + p = 50 . . . . . (i)

According to the question ,

→ 6f + p = 115 . . . . . (ii)

Solving equations (i) and (ii) ,

On subtracting them ,

→ 6f - f = 115 -50

→ 5f = 65

→ f = 65/5

→ f = 13

Substitute this in equation (i) ,

→ 13 + p = 50

→ p = 50 -13 = 37

Hence they sold 13 flags and 37 pennants .

According to the given confidence interval, we have that:

a) Since 12 ounces is part of the confidence interval, the interval does not provide convincing evidence that the true mean volume is different than 12 ounces.

b) Since 12 ounces is part of the confidence interval, the interval provides convincing evidence that the true mean volume is 12 ounces.

It is being tested if the true mean volume is different of 12 ounces, hence:

In this problem, the interval is (11.97, 12.05), hence it provides convincing evidence that the true mean volume is 12 ounces, and basically, item a is False and item b is True.
