The length of my outdoor volleyball net is 6 m plus half its own length. How long is the net?

Answer:

x = 90 , y = 43

Step-by-step explanation:

Since AB and AC are congruent , then Δ ABC is isosceles with base angles congruent , that is

∠ ABD = ∠ ACD = 47°

AD is the perpendicular bisector of BC , so

∠ ADB = x = 90

the sum of the 3 angles in Δ ABD = 180° , then

y = 180° - (90 + 47) = 180 - 137 = 43

Answer:

To calculate the interest rate for your account, you will need to use the formula for simple interest:

Interest = Principal x Rate x Time

In this case, the principal is the amount of money you deposited, or $600. The time is the number of months the money was in the account, or 18 months. And the interest is the amount of money you earned, or $31.50.

Plugging these values into the formula, we get:

$31.50 = $600 x Rate x 18

To solve for the rate, we can divide both sides of the equation by $600 and 18:

Rate = $31.50 / ($600 x 18)

Simplifying this expression gives us:

Rate = 0.01625

So, the interest rate for your account is approximately 1.625%.

The correct values for A, B and C are given as follows:

The table shows the ratios of black to white keys on pianos of various sizes, and these ratios are constant, meaning that the following proportional relationship is established:

A/13 = 18/B = 45/65 = 72/C

Then the value of A can be obtained as follows:

A/13 = 45/65

Applying cross multiplication, we have that:

65A = 13 x 45

A = 13 x 45/65

A = 9.

The value of B can be obtained as follows:

18/B = 45/65

Applying cross multiplication, we have that:

45B = 18 x 65

B = 18 x 65/45

B = 26.

Finally, the value of C can be obtained as follows:

72/C = 45/65

Applying cross multiplication, we have that:

45C = 72 x 65

C = 72 x 65/45

C = 104.

Therefore, coin is unfair ,It is true that the coin can be considered unfair.

Calculating or estimating how likely or "possible" something is to occur is the subject of probability. Words like "certain," "impossible," or "probable" can be used to express the likelihood of an event occurring. Probabilities in mathematics are always expressed as fractions, decimals, or percent with values ranging from 0 to 1.

Here,

Step 1: We see that a coin is tossed 100 times, but we only receive heads 27 times.

In other words, the odds of a head are 27/100 or 0.27.

It is thought that there will be an equal number of heads and tails on a fair coin (or very close, if not equal).

So, using a fair coin:

P(H)=P(T)=0.5

Step 2

But in this instance, P(H)=0.27, which is a long way from 0.5.

Therefore, coin is unfair.

The minimum score Sam needs to get on his final exam to get a "C" in the course is 82.

What is a probability?

A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

Given that, Sam's test scores are 62, 71, and 65.

The total score in three test is (62 + 71 + 65) = 198

Assume that, he scored x in the final test.

Total score of Sam is 198 + x.

He needs to score 70% means he needs to score 70 out of 100.

According to question,

(198 + x)/ 400 ≥ 70/100

Multiply both sides by 100:

(198 + x)/ 4 ≥ 70

Multiply both sides by 4

198 + x ≥ 280

By solving an inequality, we will see that option a is cheaper for more than 60 miles.

We know that option A charges $25 per day plus $0.15 per mile, so the cost for x miles is given by the linear equation:

A(x) = $25 + $0.15*x

While for option B the fixed cost is $10 and the cost per mile is $0.40, so the cost equation is:

B(x) = $10 + $0.40*x

The cost of option a will be smaller when:

$25 + $0.15*x < $10 + $0.40*x

$25 - $10 < $0.40*x - $0.15*x

$15 < $0.25*x

$15/$0.25 < x

60 < x

So for 60 miles the cost is the same, for x > 60 miles the cost of option a will be smaller (because the slope is smaller).

Answer:

y = 0

Step-by-step explanation:

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

x = 2 - 2y → (1)

x = - 4y + 2 → (2)

substitute x = 2 - 2y into (2)

2 - 2y = - 4y + 2 ( add 4y to both sides )

2 + 2y = 2 ( subtract 2 from both sides )

2y = 0 , then

y = 0

Equation used to represent the relation between the number of pages written to the number of hours used with constant of proportionality is

x = 4y.

As given in the question,

Let us consider number of pages write by Bill be 'x'

And number of hours represented by 'y'

Number of hours used by Bill to write 4 pages = 1 hour

Number of pages written by Bill in 1 hour = 4

Given :

Number of pages is proportional to the number of hours

⇒ x ∝ y

⇒ x = ky

Where 'k' is the constant of proportionality.

When x = 4 , y = 1

substitute the value in the equation,

4 = k(1)

⇒ k = 4

Now the required equation with the constant of proportionality k = 4 is:

x = 4y

The equation of line through the origin and (-5, 6 ) is y = [tex]-\frac{6}{5}x[/tex]

The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.

the coordinates of the origin is (0, 0) and h other coordinates are (-5, 6)

at x = 0 and y = 0

using the equation of straight line y = mx + c

0 = 0(m) + c

so c = 0

at x = -5, y = 6

6 = -5m +c

but c = 0

6 = -5m

Comparing two amounts of the same units and determining the ratio tells how much of one quantity is in the other.

when evaluating the relationship between two quantities or numbers. In general, x: y, which can be interpreted as "x is to y," is used to denote a ratio between two quantities.

Here we have

15 Cookies need 80g Oats

=> Amount of Oats for 1 cookie = 80g/15 gms

So the amount Oats for 36 Cookies = 80g/5 × 36 = 192 grams

15 Cookies need 340 grams of Maple syrup

=> Amount of Maple syrup for 1 cookie = 340/15 gram

So the amount of Maple syrup for 36 cookies = (340/15)×36 = 816 grams

By the above calculations,

For 36 Cookies we need 192 grams of Oats and 816 grams of Maple syrup

The Ratio of Oats to Maple syrup = 192 gram: 816 gram

Therefore,

The ratio of Oats to Maple syrup for 36 cookies is 192 grams: 816 grams. So the answer is Option C. 192 grams: 816 grams.

Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.

When moved, they are parallel to one another.

So, we have two sets of angles and one common side.
