Answer:

∠ A = 68°

Step-by-step explanation:

The sum of the interior angles of a kite = 360°

The opposite angles A and C are congruent

360° - (123 + 101)° = 360° - 224° = 136°

Thus since ∠ A = ∠ C, then

∠ A = [tex]\frac{136}{2}[/tex] = 68°

Answer:

-90

Step-by-step explanation:

The full circle is 360 degrees, so is you turn one way say 10 degrees, then you would need to move 350 degrees in opposite direction.

So, in this case moving 270 one way would be equivalent to moving 360-270=90 degrees in the opposite direction

Answer:

$2.34

Step-by-step explanation:

Cost of 4 boxes

The cost of 4 boxes must be the difference between the total and the strawberries

total-strawberries

12.25-2.89=9.36

4 boxes costs $9.36

Cost of 1 box

You bought 4 boxes for $9.36, and each box costs the same, so we can divide the cost by the number of boxes

cost/boxes

9.36/4=2.34

Each box of cereal costs $2.34

Answer:

$2.34

Step-by-step explanation:

So first you have to subtract 2.89 from 12.25. then you should get 9.36. After you get that you have to divide 9.36 by 4 because there are 4 boxes of cereal and we need to know how much is the cost of one box of cereal. ONce you get that the answer would be $2.34.

Answer:

15

Step-by-step explanation:

An isosceles triangle has equal base angles.

Hence,

[tex] 3x=5x-30\\

\implies 30=2x\\

\implies x=15[/tex]

Answer:

C

Step-by-step explanation:

Well all triangles need to be equal to 180°. When you substitute a, b, and d in for x, the result are bigger than 180 not including the 3rd angle. With C the angles equal 45° and 45° angle which leave the appropriate sized angle for the 3rd angle at 90°. So x is equal to 15.

The correct option is c. 637 cm is not equal to 63.7 mm.

To solve this problem, we need to convert each of the given units to millimeters (mm) and then compare them to 63.7 mm.

a. [tex]\(6.37 \times 10^4 \, \mu m\)[/tex] to mm:

Since 1 mm = \(1 \times 10^3 \, \mu m\), we have

\[6.37 \times 10^4 \, \mu m \times \frac{1 \, mm}{1 \times 10^3 \, \mu m} = 63.7 \, mm\]

This is equal to 63.7 mm.

b. [tex]\(6.37 \times 10^{-5} \, km\)[/tex] to mm:

Since 1 km = [tex]\(1 \times 10^6 \, mm\)[/tex], we have

[tex]\[6.37 \times 10^{-5} \, km \times \frac{1 \times 10^6 \, mm}{1 \, km} = 63.7 \, mm\][/tex]

This is also equal to 63.7 mm.

c. 637 cm to mm:

Since 1 cm = 10 mm, we have

[tex]\[637 \, cm \times \frac{10 \, mm}{1 \, cm} = 6370 \, mm\][/tex]

This is not equal to 63.7 mm.

d. 0.637 dm to mm:

Since 1 dm = 100 mm, we have

[tex]\[0.637 \, dm \times \frac{100 \, mm}{1 \, dm} = 63.7 \, mm\][/tex]

This is equal to 63.7 mm.

Therefore, the only option that is not equal to 63.7 mm is 637 cm.

Answer:

$260

Step-by-step explanation:

you multiply $65 by 4 for the set of four and the product is $260.

Answer:

A set of 4 tires cost $260.

Step-by-step explanation:

It is given that each tire is sold for $65. In order to find a set of 4 tires, you have to multiply it by 4 :

1 tire = $65

4 tires = $65×4

= $260

Answer:

Step-by-step explanation:

The wording "a rate proportional to its size" is an indication that growth (or decay) is exponential.

1) For many problems involving exponential growth, I like to use the numbers given in the problem statement as follows.

  population = (initial population) × (growth factor)^(t/(growth period))

where the "growth period" is the period of time in which the population is multiplied by the "growth factor".

Here, we're given ...

  (initial population) = 400

  (growth factor) = 800/400 = 2

  (growth period) = 2 . . . . hours

So, our population function can be written as ...

  P(t) = 400×2^(t/2)

__

2) Putting t=8 into the formula, we get ...

  P(8) = 400×2^(8/2) = 400×16 = 6400

After 8 hours, the population will be 6400.

__

3) Fill in the given number and solve for t.

  2270 = 400×2^(t/2)

  2270/400 = 2^(t/2)

Taking logs, we have ...

  log(227/40) = (t/2)log(2)

  t = 2×log(227/40)/log(2) ≈ 5.009

After 5.0 hours, the population will reach 2270.

Answer:

B) It decreases 22% per year.

Step-by-step explanation:

We are given that The value, v(.r), of his  portfolio can be modeled with the function : [tex]y(x) = 30,000(0.78)^x[/tex]

Where x is the number of years since he made his investment.

Formula :[tex]P(1-r)^t=A[/tex]

Where P = Principal

r = rate of decrease

t = time

A = Amount after t years

So, On comparing

P = 30000

t=x

A=y(x)

[tex]1-r=0.78[/tex]

[tex]\Rightarrow 1-0.78=r[/tex]

[tex]\Rightarrow 0.22=r[/tex]

So, r = 0.22

r=22%

So, Rate of decrease is 22%

So, Option B is true,

It decreases 22% per year.

Answer:

A. 37 degrees

Step-by-step explanation:

Since QR is tangent to the circle, it means that is in a right angle. Meaning that angle Q is equal to 90 degrees.

Since you know what two angles are equal to, you can use the triangle angle sum theorem by setting them all up to 180.

53+90+x=180

Simplify the answer

143+x=180

Subtract 143 from both sides

X=37

:

The measure of angle ∠QRP = 37°.

Tangent to a circle is a straight line which touches the circle at only one point and the point of contact is perpendicular to the radius drawn from the center of the circle.

In the given question

Line segment PQ is radius, Line segment QR is is a tangent to the circle(P) at point Q.

Here QR is perpendicular to PQ because tangent to a circle is perpendicular to the point of contact and a line (PQ) drawn from the center of the circle (P).

∴ ∠PQR = 90° given ∠QPR = 53° We have to find ∠QRP .

We know the sum of all the interior angles in a triangle is = 180°

∠PQR + ∠QPR + ∠QRP = 180°

         90° + 53° + ∠QRP = 180°

∠QRP = 180° - (90° + 53°)

∠QRP = 180° - 143°

∠QRP = 37°

Answer:

BC = 15.01

Step-by-step explanation:

Solve this question using a trigonometry ratio, which you can remember them all with SohCahToa, which says:

sinθ = opp / hyp

cosθ = adj / hyp

tanθ = opp / adj

θ means the "angle of reference" (angle we are talking about).

In this problem, θ is A = 65°,

To decide which trig. ratio to use, find out which sides we want to use. We will use AC = 7 because we know it.

We also use BC because we need to find it.

In relation to ∠A or θ, AC is adjacent and BC is opposite.

The ratio with adjacent and opposite is tangent.

tanθ = opp / adj              Substitute the variables for this question

tanA = BC / AC               Substitute the values you know

tan65° = BC / 7               Rearrange this and isolate C

BC = 7tan65°                  Multiply 7 and tan65 to find the missing side

BC = 15.011548......          Exact answer on your calculator

A Quick Guide to the 30-60-90 Degree Triangle

The 30-60-90 degree triangle is in the shape of half an equilateral triangle, cut straight down the middle along its altitude. It has angles of 30°, 60°, and 90°. In any 30-60-90 triangle, you see the following: The shortest leg is across from the 30-degree angle, the length of the hypotenuse is always double the length of the shortest leg, you can find the long leg by multiplying the short leg by the square root of 3.

Note: The hypotenuse is the longest side in a right triangle, which is different from the long leg. The long leg is the leg opposite the 60-degree angle.

Two of the most common right triangles are 30-60-90 and the 45-45-90 degree triangles. All 30-60-90 triangles, have sides with the same basic ratio. If you look at the 30–60–90-degree triangle in radians, it translates to the following:

30, 60, and 90 degrees expressed in radians.

The figure illustrates the ratio of the sides for the 30-60-90-degree triangle.

A 30-60-90-degree right triangle.

A 30-60-90-degree right triangle.

If you know one side of a 30-60-90 triangle, you can find the other two by using shortcuts. Here are the three situations you come across when doing these calculations:

Type 1: You know the short leg (the side across from the 30-degree angle). Double its length to find the hypotenuse. You can multiply the short side by the square root of 3 to find the long leg.

Type 2: You know the hypotenuse. Divide the hypotenuse by 2 to find the short side. Multiply this answer by the square root of 3 to find the long leg.

Type 3: You know the long leg (the side across from the 60-degree angle). Divide this side by the square root of 3 to find the short side. Double that figure to find the hypotenuse.

Finding the other sides of a 30-60-90 triangle when you know the hypotenuse.

Finding the other sides of a 30-60-90 triangle when you know the hypotenuse.

In the triangle TRI in this figure, the hypotenuse is 14 inches long; how long are the other sides?

Because you have the hypotenuse TR = 14, you can divide by 2 to get the short side: RI = 7. Now you multiply this length by the square root of 3 to get the long side:

The long side of a 30-60-90-degree triangle.

We know angle P is 90 degrees because of Thales Theorem, and angle N is 60 degrees. Because the angles in a triangle have to add up to 180 degrees, angle PMN has to be 30 degrees.

Angle QMO is half of angle PMN, so it's 15 degrees. Angle MQO is equal to angle QMO because the radii make Triangle OQM isosceles, so angle MQO is 15 degrees.

Answer:

yes this is right

The final simplified expression is 2 over the square root of 5, represented as  [tex]\( \frac{2}{\sqrt{5}} \).[/tex]

Let's break it down step by step:

1. Simplify the square roots:

[tex]- \(\sqrt{4}\) equals 2 because \(2 \times 2 = 4\). So, \(\sqrt{4} = 2\).[/tex]

  - We have [tex]\(\sqrt{5}\)[/tex] in the denominator, which cannot be simplified further because 5 is a prime number and doesn't have any perfect square factors.

2. Substitute the simplified square roots:

  - After simplifying [tex]\(\sqrt{4}\)[/tex] to 2, the expression becomes [tex]\(\frac{3 \times 2}{3\sqrt{5}}\).[/tex]

3. Cancel out the common factor:

  - Both the numerator and the denominator have a factor of 3. So, we can cancel out 3 from both sides:

[tex]\[\frac{3 \times 2}{3\sqrt{5}} = \frac{2}{\sqrt{5}}\][/tex]

4. Final simplification:

  - The expression [tex]\(\frac{2}{\sqrt{5}}\)[/tex] is simplified as far as it can go because the square root of 5 cannot be simplified further.

So, the simplified expression is [tex]\(\frac{2}{\sqrt{5}}\).[/tex]
