Answer:

x + y = 60

Step-by-step explanation:

In the given figure, we have two lines that intersect each other at one point.

Therefore, the opposite angles are equal to each other and we can write them in the form of an equation as:

2y - 5 = 95 --- (1)

3x + 55 = 85 --- (2)

Now solving each of the equations to find the value of x and y.

For y:

2y - 5 = 95

2y = 95 + 5

2y = 100

y = 50

For x:

3x + 55 = 85

3x = 85 -55

3x = 30

x = 10

Therefore, x + y = 10 + 50 = 60.

Answer:

56 = (0.85)w

Final answer:

After converting their completion fractions to decimal form, Jose finished more of the race than Jenna after 30 minutes, with Jose at 2/3 (approximately 0.6667) and Jenna at 7/12 (approximately 0.5833).

Explanation:

Jose and Jenna competed in a bike race. After 30 minutes, Jose had finished 2/3 of the race, and Jenna had finished 7/12 of the race. To determine who had finished more of the race, we can compare these two fractions by finding a common denominator or converting them to decimal form.

First, let's convert them to decimal form:

2/3 is approximately 0.6667

7/12 is approximately 0.5833

Comparing the decimal values, we can see that Jose's completion (0.6667) is greater than Jenna's (0.5833). Therefore, Jose had finished more of the race after 30 minutes.

Answer:

A = 10w

Step-by-step explanation:

In the area formula, the coefficient of width is length. Here, that is ...

... A = 7w

7 is the coefficient of the width. Increasing it by 3 makes it be 10, so we have ...

... A' = 10w

_____

Comment on the problem statement

The problem does not make it clear whether area stays the same as the coefficient increases. We have assumed that it does not.

Also, the coefficient of width in the area formula has units of inches. "Increases by 3" makes no sense in this context. It would make sense for it to increase by 3 inches. The result is very different if the increase is 3 microns, for example.

x = 8.5

The other two sides are given in the diagram.

The Pythagorean theorem tells you ...

... 19² = 17² +x²

Subtracting 17², we have ...

... x² = 361 -289 = 72

Taking the square root gives x.

... x = √72 = 6√2

... x ≈ 8.5

1/3, 1/4, 1/5

40% = 40/100 = 2/5

Any fraction with a numerator of 2 and a denominator larger than 5 will be less than 40%, for example.

So, we can choose 2/6 = 1/3, 2/8 = 1/4, and 2/10 = 1/5 as some such values.

_____

We could also choose something like 39.99% = 3999/10000, or 1% = 1/100.

Answer:

A = 4200 ft^2

Step-by-step explanation:

We know the formula for area is

A = l*w

We need to have the same units

convert yd to ft

1 yd = 3ft

Multiply each by 70

70 yds = 210 ft

A = 210 *20

A = 4200 ft^2

The area of the pavement section is 4200 square feet, computed by converting the length to the same unit as the width and multiplying width by length.

The subject of this question is the calculation of the area of a rectangle. The rectangle in question is a section of pavement with a width of 20 ft and a length of 70 yd. Before calculating, it's important to have the measurements in the same units. Converting 70 yards to feet (since 1 yard equals 3 feet) we get 210 feet. The formula to calculate the area of a rectangle is Area = Width x Length. Substituting the given values into the formula, we get: Area = 20 ft x 210 ft which equals 4200 square feet. Therefore, the pavement section's area is 4200 square feet.

The correct option is the last:

[tex] a_n = -2a_{n-1}+1 [/tex]

In fact, every term in the sequence is one more than twice the opposite of the previous one:

We start with 3. Twice its opposite is -6. Plus one, we get -5.

We start with -5. Twice its opposite is 10. Plus one, we get 11.

We start with 11. Twice its opposite is -22. Plus one, we get -21.

The recursive formula is: [tex]a_n-a_{n-1} = (-8)(-1)^n \times (2)^{n-2}[/tex]

To find a recursive formula for the given sequence, we need to determine the relation between consecutive terms.

Let's denote the sequence as an, where:

[tex]a_1 = 3\\a_2 = -5\\a_3 = 11\\a_4 = -21\\[/tex]

First, let's calculate the differences between consecutive terms:

[tex]a_2 - a_1 = -5 - 3 = -8\\a_3 - a_2 = 11 - (-5) = 16\\a_4 - a_3 = -21 - 11 = -32[/tex]

We observe that each difference is a multiple of 8 and that each difference is twice the previous difference but with alternating signs.

The recursive formula can be defined as:

[tex]a_n-a_{n-1} = (-8)(-1)^n \times (2)^{n-2}[/tex]

Thus the recursive formula is: [tex]a_n-a_{n-1} = (-8)(-1)^n \times (2)^{n-2}[/tex]

Answer:

The distance from he ball to the goal is 11.85 feet (Approx) .

Step-by-step explanation:

As given

The angle of elevation from a soccer ball on the ground to the top of the goal is 34° .

If the goal is 8 feet tall.

Now by using the trigonometric identity .

[tex]tan \theta = \frac{Perpendicular}{Base}[/tex]

As shown in the diagram given below

[tex]\theta = 34^{\circ}[/tex]

Perpendicular = AB = 8 feet

Base = BC

Put all the values in the identity .

[tex]tan\ 34^{\circ} = \frac{AB}{BC}[/tex]

[tex]tan\ 34^{\circ} = \frac{8}{BC}[/tex]

[tex]tan\ 34^{\circ} = 0.675\ (Approx)[/tex]

[tex]BC = \frac{8}{0.675}[/tex]

BC = 11.85 feet (Approx)

Therefore the distance from he ball to the goal is 11.85 feet (Approx) .

To calculate the distance from the soccer ball to the goal with an angle of elevation of 34 degrees and a goal height of 8 feet, use the tangent trigonometric ratio. The distance is found to be approximately 11.86 feet.

Given the angle of elevation is 34 degrees and the goal's height is 8 feet, we're looking to calculate the adjacent side (distance from the ball to the goal) in a right-angled triangle where the opposite side (goal's height) and the angle are known.

To calculate the distance (let's call it d), we use the tangent function:

So, d = 8/tan(34 degrees).

Calculating this, we find:

Therefore, the distance from the soccer ball to the goal is approximately 11.86 feet.

Answer :

The proof is as follows :

Step-by-step explanation:

Let NC = x

⇒ AB = 3x and AN = 2x

In Δ ABN, By using Pythagoras theorem,

AB² = BN² + AN²

⇒ BN² = AB² - AN²

⇒ BN² = (3x)² - (2x)²

⇒ BN² = 5x²

⇒ BN = x√5  .......................(1)

Now in ΔANC , Using Pythagoras theorem We have,

AC² = NC² + AN²

⇒ AC² = x² + (2x)²

⇒ AC² = 5x²

⇒ AC = x√5   ....................(2)

From equations (1) and (2) We get,

Answer:

‪0.155922‬

Step-by-step explanation:

Answer: 0.1562 kilograms

Step-by-step explanation: To convert 5.5 ounces into kilograms, we first convert 5.5 ounces into grams using the conversion factor 1 oz = 28.4 g.

Since we are going from a larger unit "ounces" to a smaller unit "grams" we multiply 5.5 by the conversion factor which is 28.4 to get 156.2.

This means that 5.5 ounces is equal to 156.2 grams.

Next, we convert 156.2 grams into kilograms using the conversion factor

1 kilogram = 1,000 grams. Since we are going from a smaller unit "grams" to a

larger unit "kilograms" we divide 156.2 by the conversion factor which is 1,000

and we get 0.1562 kilograms.

Therefore, 5.5 ounces is equal to approximately 0.1562 kilograms.

Answer:

2^(8/9) in²

Step-by-step explanation:

Make use of the identity ...

... (a^b)^c = a^(bc)

Here, you have a=2, b=4/9, c=2. There is an additional factor (units of inches) inside the parentheses on the left. For that, you use the identity

... (ab)^c = a^c·b^c

In this case a = 2^(4/9), b = in, c = 2.

So, the working of your problem is ...

... Area = (side length)^2 = (2^(4/9) in)^2 = (2^(4/9))^2 in^2

... = 2^(4/9·2) in^2 = 2^(8/9) in^2

Answer:

Steplo-by-step explanation:loan is 1200.

The interest rate is 6.50

Pp 46.90

Cumulative payment $53.4

Total payments$1,282.93

Final answer:

Lane will pay a total of $156 in simple interest on the loan of $1200 over 2 years, calculated using the simple interest formula: I = PRT.

Explanation:

Lane borrowed $1200 at a simple interest rate of 6.5% for a period of 2 years. To calculate the total amount of interest that will be paid on the loan, we can use the simple interest formula, which is:

I = PRT

where I is the interest, P is the principal amount borrowed, R is the interest rate per year (expressed as a decimal), and T is the time in years the money is borrowed for.

First, we convert R to a decimal by dividing it by 100:

R = 6.5% / 100 = 0.065

Next, we substitute the values into the formula:

I = $1200 × 0.065 × 2

I = $1200 × 0.13

I = $156

Therefore, the total amount of interest that Lane will be paying on the loan over the next 2 years is $156.

Using the smallest number she has, 9 daisies..

9 students did not study in either the cafeteria or the student lounge.

How to find the number

To find the number of students who did not study in either the cafeteria or the student lounge, we solve as follows

Let

C = 92

L = 86

C ∩ L = 40

We find the number in either C, L or C ∩ L

= (92 - 40) + (86 - 40) + 40

= 52 + 46 + 40

= 138

The number  did not study in either the cafeteria or the student lounge

= 147 - 138
