Answer:

x = 6

Step-by-step explanation:

5x - 7 and 23 are vertical angles and are congruent , then

5x - 7 = 23 ( add 7 to both sides )

5x = 30 ( divide both sides by 5 )

x = 6

Answer: 11.38

Step-by-step explanation:

I just did this math nation question and that’s what they said the answer was

The solution is, Length of the shadow = 11.4 m.

Trigonometry can be stated as the study of the relationships between the angles and the lengths of the sides of triangles.

here, we have,

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

here, we have,

Given the graph:

The length of the shadow = y - x.

• To find x:

tan 21 = x/25

so, we get,

x = 25 * tan 21

  =9.6m

• To find y:

tan 40 = y/25

so, we get,

y = 25* tan40

  = 21m

Length of the shadow:

length = 21 - 9.6 m

           = 11.4m

so, we get,

Length of the shadow = 11.4 m

40

just do 5 × 8

i remember this lesson when i was grade 4:)

Answer:

5 = side a

3 = side c

angle B = 62 degrees

JK is side b

Use the Law of Cosines to find the length of side b.

b^2 = a^2 + c^2 − 2ac cos(B)

b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)

b^2 = (25 + 9) − 30 x 0.469

b^2 = 34 - 30 x 0.469

b^2 = 34 - 14.084

b^2 = 19.916

b = √19.916

b = 4.463

Answer:

Step-by-step explanation:

If 2p + 6a = $14

and 3p + 9a = $21

then the following would also be true:

1p + 3a = $7

If p = pear and a = apple, how much would each cost?  The unit prices can be determined by looking at the pattern. You can use multiplication to solve the problem.  

For example, 1p + 3a*2 = $7

p = $1/each

a = $2/each or $6 total

I hope this helps you out.

Answer:

the unit for pears and apples are : 35

Step-by-step explanation:

14 + 21 = 35

Answer: 2000

Step-by-step explanation:

Percentage supporting home team = 65%

Percentage supporting visiting team = 35%

Number of people supporting home team = 1300

Let the total number of people attending the game be represented by x.

Therefore, 65% of x = 1300

65/100 × x = 1300

0.65 × x = 1300

0.65x = 1300

x = 1300 / 0.65

x = 2000

Therefore 2000 people attended the game.

Answer:

its 105 yw pls mark me brainliest pls

Step-by-step explanation:

105 students  prefer cheese pizza.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

If Larry surveyed 20 students then 14 students prefer cheese pizza.

So, the fraction for students who choose prefer cheese pizza is

= 14/20

Now, there are 150 students then number of students who prefer cheese pizza

= 14/20 x 150

=  2100/20

= 105

Hence, 105 students  prefer cheese pizza.

1) In 1910, Halley's Comet was 21.37 million kilometers close to Earth.

2) Given that Halley's Comet orbits the sun at about 75 years, and that the last time it passed near the Earth was in 1986, the years in which it will happen again will be 2061, 2136 and 2211.

3) Earth is 794 times larger in diameter than Halley's Comet.

Since in 1910, Halley's Comet traveled close to Earth about 1/7 of the distance from the Earth to the Sun, and Earth's distance from the Sun is 149.6 million kilometers, to determine 1) how close was Halley's Comet to Earth in 1910, 2) estimate the next 3 years when Halley's Comet will appear, and 3) if the core of Halley's Comet is oblong in shape, with its longest dimension 16 km long, and Earth's diameter is about 12,700 km, how many times larger in diameter is Earth than Halley's Comet, the following calculations must be performed:

The relationship between Halley's comet and the earth is an illustration of proportions

The given parameters are:

(a) The distance

The distance which Halley's comet get to is calculated using:

[tex]d = \frac 17 \times 149.6\ million\ km[/tex]

So, we have:

[tex]d = 21.37\ million\ km[/tex]

Hence, Halley's comet was 21.37 million kilometers close to the earth in 1910.

(b) The next three years it will appear

From the complete question, the comet is visible every 74 years.

It appears in 1910.

So, the next three years are:

[tex]Year\ 1 = 1910 + 74 = 1984[/tex]

[tex]Year\ 2 = 1984 + 74 = 2058[/tex]

[tex]Year\ 3 = 2058 + 74 = 2132[/tex]

Hence, the comet will appear in 1984, 2058 and 2132.

(c) The number of times the earth is larger

The diameter of the earth is given as: 12700 km, while the longest dimension of the oblong shaped comet is 16 km.

So, the number of times (n) which the earth is greater than the comet is:

[tex]n = \frac{12700}{16}[/tex]

[tex]n = 794[/tex] --- approximated

Hence, the diameter of the earth is 794 times larger than Halley's Comet.
