Four times a number,decreased by two is five.

The measure of angles are 22.5 degree and 67.5 degree

Solution:

Given that, measures of two complementary angles are in ratio 1 : 3

one angle : another angle = 1 : 3

Let the first complementary angle 1x

Let the another complementary angle be 3x

If the angles are complementary, then their sum is 90 degrees

Therefore,

1x + 3x = 90

4x = 90

x = 22.5

Then, first angle = 1x = 1(22.5) = 22.5

Another angle = 3x = 3(22.5) = 67.5

Thus the measure of angles are 22.5 degree and 67.5 degree

Price of the book in her store is $ 25

Solution:

Given that, The bookstore buys a book for 20$

She marked up the price by 25% to sell it in her store

To find: Price of book in her store

From given,

Cost price = $ 20

Markup rate = 25 %

Which means, 25 % of $ 20 is markup price

[tex]Markup\ Price = 25 \% \text{ of } 20\\\\Markup\ Price = \frac{25}{100} \times 20\\\\Markup\ Price = 0.25 \times 20\\\\Markup\ Price = 5[/tex]

Thus markup price is $ 5

Price of the book in her store = cost price + markup price

Price of the book in her store = 20 + 5 = 25

Thus Price of the book in her store is $ 25

Base of triangle is: 8 cm

Step-by-step explanation:

Let h be height of triangle and

b be the base

According to given statement "The height of a triangle is 7 cm longer than its base."

[tex]h = b+7[/tex]

Area of triangle = 60 square cm

The formula for the area of triangle is given by:

[tex]A = \frac{1}{2} * b * h\\60 = \frac{1}{2} * b * (b+7)\\120 = b(b+7)\\120 = b^2+7b\\b^2+7b-120 = 0\\b^2+15b-8b-120 = 0\\b(b+15)-8(b+15) = 0\\(b+15)(b-8) = 0\\Now\\b+15 = 0 => b=-15\\b-8 = 0 => b = 8[/tex]

As the length cannot be negative,

Base = 8 cm

Height = b+7 = 8+7 =15 cm

Answer: Square.

Step-by-step explanation:

First it is important to know the following definitions:

1. A Quadrilateral is defined as a polygon that has four sides and, therefore, four vertices.

2. A Square is a Regular Quadrilateral that has the following properties:

- All its sides have equal length.

- Its opposite sides are parallel.

- The measure of each Internal angle is 90 degrees (which are also called "Right angles").

According to the information given in the exercise, the poster Cecily made has the shape of a Quadrilateral. All the angles of this quadrilateral are congruent (this means that they have equal measure) and all the sides are also congruent (they have the same length).

Therefore, based on the explained before, you can conclude that it is a Square.

Final answer:

To determine the cost of each bottle in a $3.48 six pack of soda, divide the total cost by the number of bottles, which results in each bottle costing $0.58.

Explanation:

To find out how much each bottle of soda costs when a six pack of soda costs $3.48, we need to divide the total cost by the number of bottles in a pack. Since there are six bottles in a six pack, we take the total cost of $3.48 and divide it by 6.

The calculation will look like this:

Cost per bottle = Total cost of six pack ÷ Number of bottles

Cost per bottle = $3.48 ÷ 6

Cost per bottle = $0.58

Therefore, each bottle of soda costs $0.58.

The equation of a straight line is

-3 x+5 y=15

Step-by-step explanation:

Given x - intercept of (-5,0) and y- intercept is (0,3)

here (-5,0 ) point lie on x- axis and (0,3) this point lie on y- axis

we know that the x- intercept  'a' and y- intercept 'b'  formula is

[tex]\frac{x}{a} +\frac{y}{b} = 1[/tex]

so given x - intercept a =-5 and y- intercept is b= 3

now the straight line equation is [tex]\frac{x}{-5} +\frac{y}{3} =1[/tex]

now simplify [tex]\frac{-3 x+5 y}{15} =1[/tex]

[tex]-3 x+5 y=15[/tex]

Step-by-step explanation:

On January 1, 2006, I have $100 in a savings account that earns interest at a rate of 1% per month. On the last day of every month, I deposit $75 in the account, beginning in January.

So, at the end of the month of January, the added amount to the account is $75 and 1% of $100 i.e. 1$.

Then, total $(75 + 1) = $76 is being added at the end of each month.

So, the recursive rule for account balance at the beginning of the nth month will be given by [tex]b_{1} = 100[/tex] and [tex]b_{n + 1} = b_{n} + 76[/tex] where, n = 1, 2, 3, ..... (Answer)

The amount of water already in the jug is 5.29 L. To fill the jug up to 5.85 L, 0.56 L more water is needed.

This is a simple arithmetic problem involving addition and subtraction. Given that you need to fill a jug with 5.85 L of water, you have already filled it with 2.45 L and then added 2.84 L more. The total amount of water in the jug now can be found by adding these two amounts together, giving 2.45 L + 2.84 L = 5.29 L. To find out how much more water you need, subtract this amount from the total capacity of the jug: 5.85 L - 5.29 L = 0.56 L. Therefore, you need 0.56 L more water to fill the jug.

In order to find the slope, we may use the formula:

Slope = (y2−y1)/(x2-x1)

Now, let's identify the values. Say, point a is the first point and b is the second. This means that:

x1 = 3

y1 = 2

x2 = 7

y2 = 10

Let's plug in the values:

=(10-2)/(7-3)

=8/4

=2

Now, to determine if the slope is downward or upward, positive slope means upward from left to right while negative slope means downward from left to right.

So since our slope is positive 2, it is upward.

FINAL ANSWER:

Slope = 2

It slopes upward from left to right.

The correct answer is (C) $48. Hence the correct option is c.

1. Identify the relevant information:

From the table, we know Alfred earns $8 per time he weeds the garden.

He weeded the garden 6 times.

2. Calculate his total earnings from weeding:

To find the total amount Alfred earned, we multiply the amount he earns per weeding session by the number of times he weeded:

Total earnings = Number of times weeded * Earnings per weeding

Total earnings = 6 times * $8/time = $48

Therefore, Alfred earned $48 from weeding the garden.

Hence the correct option is c.

Complete question:

Alfred does chores to earn money in the summer. The table shows the amount he earns per chore.

Chore Amount Earned ($)

mow lawn $10

wash car         $5

weed garden  $8

Suppose Alfred weeded the garden 6 times in the summer. How much did he earn weeding?

(A) $30

(B) $60

(C ) $48

(D) $75

The answer is option B - $48. Alfred earned $48 from weeding the garden 6 times, as each weeding earned him $8 and $8 multiplied by 6 gives $48.

The question involves a basic arithmetic calculation to determine how much money Alfred earned for weeding the garden multiple times. We need to multiply the amount Alfred earns per instance of weeding by the number of times he performed the task.

Given that Alfred earns $8 for weeding the garden once and he weeded the garden 6 times over the summer, the total earning from weeding can be calculated as:

Amount Earned Weeding = Earned per Weeding × Number of Weedings

Amount Earned Weeding = $8 × 6 = $48

Therefore, Alfred earned $48 from weeding the garden 6 times in the summer.

The question is:

Alfred does chores to earn money in the summer. The table shows the amount he earns per chore.

Answer:

The player throws 127.3 ft from second base to home plate.

Step-by-step explanation:

Given:

Distance from home to first base = 90 ft

Distance from first base to second base = 90 ft

We need to find the distance from second base to home.

Solution:

Now we can assume the complete scenario to be formed as a right angled triangle with two sides given and to find the third side.

Now by using Pythagoras theorem which states that;

Square of the hypotenuse side is equal to sum of squares of other two sides.

framing in equation form we get;

distance from second base to home = [tex]\sqrt{90^2+90^2}= 127.27 \ ft[/tex]

Rounding to nearest tent we get;

distance from second base to home = 127.3 ft

Hence The player throws 127.3 ft from second base to home plate.

The distance from second base to home plate is calculated using the Pythagorean theorem because it's the diagonal of the square formed by the bases, which are 90 feet apart. The resulting diagonal (hypotenuse) is approximately 127.3 feet, rounding to the nearest tenth.

The question seems to imply that the distance is known in the context of a standard baseball diamond, but unfortunately, it has not provided us with the exact distance from second base to home plate. However, if we refer to the standard dimensions of a baseball field, the distance from home plate to second base is not a straight line but the diagonal of a square formed by the bases. Each base in professional baseball is 90 feet apart, so to find the distance from second base to home plate, which is the hypotenuse of the square (assuming perfect square dimensions), we would use the Pythagorean theorem.

Using the theorem a² + b² = c², where 'a' and 'b' are the sides of the square (90 feet each) and 'c' is the hypotenuse (distance from second base to home plate), we can calculate:

a² = b² = 90²

Therefore,
c² = 90² + 90² = 8100 + 8100 = 16200

Then, solving for 'c' gives us:

c = √16200 ≈ 127.3 feet

So the baseball player throws the ball approximately 127.3 feet from second base to home plate, rounding to the nearest tenth.

Answer:

  24 cm

Step-by-step explanation:

The triangle formed by the chord, its bisector, and a radius is a right triangle with hypotenuse 13 and one side of length 5. These are two of the numbers in the 5-12-13 Pythagorean triple, so we know that half the chord has length 12.

The chord is 24 cm long.

_____

In case you haven't memorized some of the more commonly used Pythagorean triples, you can find the half-chord length (h) using the Pythagorean theorem:

  13² = 5² + h²

  169 -25 = h²

  √144 = h = 12

The half-chord length is 12, so the full chord length is 24 centimeters.
