One-half times 22 times 23.1

One-half ties 15.9 times 31.9

The area of triangles is One-half times 22 times 23.1 and One-half ties 15.9 times 31.9. Then the correct options are A and E.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Triangle X Y Z has a base of 22 and a height of 23.1.

Then the area of the triangle will be

[tex]\rm Area\ triangle = \dfrac{1}{2} \times 22 \times 23.1[/tex]

The triangle also has a base of 31.9 and a height of 15.9.

Then the area of the triangle will be

Answer:

Step-by-step explanation:

Average Speed = Total Distance / Total Time

Total Distance = 50+ 70 + 10 + 60 = 190 Miles

Total Time = 1 + 1 + 1/2 + 1/2 =  3 hours

Average speed = 190 / 3 = 63.3 mph

Answer:

[tex]Quarters = 41[/tex]

[tex]Dimes = 18[/tex]

Step-by-step explanation:

Given

[tex]Coins = 59[/tex]

[tex]Worth = \$12.05[/tex]

[tex]d = dimes[/tex]

[tex]q = quarters[/tex]

Required

The number of each coin

The total coins can be represented as:

[tex]d + q = 59[/tex]

[tex]1\ quarter = \$0.25 \\ 1\ dime = \$0.10[/tex]

So, the worth of the coin is:

[tex]0.25q + 0.10d = 12.05[/tex]

The equations to solve are:

[tex]0.25q + 0.10d = 12.05[/tex]

[tex]d + q = 59[/tex]

Make d the subject in: [tex]d + q = 59[/tex]

[tex]d =59 - q[/tex]

Substitute [tex]d =59 - q[/tex] in [tex]0.25q + 0.10d = 12.05[/tex]

[tex]0.25q + 0.10(59 - q) = 12.05[/tex]

[tex]0.25q + 5.9 - 0.10q = 12.05[/tex]

Collect like terms

[tex]0.25q - 0.10q = 12.05 - 5.9[/tex]

[tex]0.15q = 6.15[/tex]

Solve for q

[tex]q=\frac{6.15}{0.15}[/tex]

[tex]q=41[/tex]

Substitute [tex]q=41[/tex] in [tex]d =59 - q[/tex]

[tex]d = 59 - 41[/tex]

[tex]d = 18[/tex]

So:

[tex]Quarters = 41[/tex]

[tex]Dimes = 18[/tex]

Answer:

38.42cm

Step-by-step explanation:

Given that the length of the sides of a rectangle are 30 cm and 24 cm.

The length of the diagonal can be obtiaed using Pythagoras rule

Length of the diagonal = hypotenus

Hypotenus = sqrt(opposite ² + adjacent ²)

Opposite and adjacent sides are 30cm and 24 cm

Hypotenus = sqrt(30² + 24²)

Hypotenus = sqrt(900 + 576)

Hypotenus = sqrt(1476)

Hypotenus = 38.419

Length of diagonal = 38.42cm

Answer: x = 13.4

Step-by-step explanation:

1. Subtract 90 degrees and 33 degrees to get angle X, which is 57 degrees.

2. Using Laws of Sine, plug in the known elements of the triangle:

(16) / (sin(90)) = (x) / (sin(57))

3. Cross multiply, this will leave 16sin(57) = xsin(90)

4. Divide sin(90) to the other side, leaving x = (16sin(57)) / (sin(90))

5. Plug this into a calculator and your final answer should be 13.4

Answer:

Step-by-step explanation:

Answer:

The decrease is exponential.

Step-by-step explanation:

An exponential decrease is something like:

f(x) = A*(r)^x      with 0 < r < 1

A linear decrease is something like:

g(x) = -a*x + b               with a > 0

First ai general formula.

If you have a quantity Q, decreased by an X%, the new quantity will be:

New Quantity = Q - Q*(X%/100%)

Now let's look at the question:

Suppose that the original price of the computer component is K

And the price as a function of the year is P(y)

Then we know that, in the year zero, the price is K.

P(0) = K

One year after, the price decreases by 2.25%

Then:

P(1) = K - K*(2.25%/100%) = K*(1 - 0.0225)

After another year, we will have another decrease of 2.25%

Then:

P(2) =  K*(1 - 0.0225) -  K*(1 - 0.0225)*(2.25%/100%)

P(2) = K*(1 - 0.0225)*(1 - 0.0225) = K*(1 - 0.0225)^2

We already can see the pattern, we can expect that in the year y, the price of the component will be:

P(y) = K*(1 - 0.0225)^y

This clearly is an exponential decrease.

Answer:

The answer is B 5.4 units

Step-by-step explanation:

The approximate value of PQ in the right angle triangle is 5.4 units.

A right angle triangle has one of its angles as 90 degrees. Therefore, the sides can be found by trigonometric ratios.

Hence,

sin 50 = opposite / hypotenuse

sin 50 = PQ / 7

cross multiply

PQ = 7 sin 50°

PQ = 7 × 0.76604444311

PQ = 5.36231110183

PQ = 5.4 units
