Answer:

h = 11.3 cm

use tane rule:

[tex]\sf tan(x)= \dfrac{opposite}{adjacent}[/tex]

Here:

=========

[tex]\hookrightarrow \sf tan(37)= \dfrac{h}{15}[/tex]

[tex]\hookrightarrow \sf h = tan(37) * 15[/tex]

[tex]\hookrightarrow \sf h = 11.3 \ cm[/tex]

The approximate value of the speed of the car in feet per second is A. 5.32 ft/s.

An equation is an expression that shows the relationship between two or more numbers and variables. In this case, tan(θ) = s² / 49

sinθ = 1/2

θ = sin⁻¹ (0.5) = 30⁰

tan(30) = s² / 49

s = 5.32 ft/s

Therefore, the approximate value of the speed of the car in feet per second is 5.32 ft/s.

Step-by-step explanation:

Answer:

102 miles

Step-by-step explanation:

In 2 hours there are 7200 seconds ([tex]60*60 = 3600 * 2 = 7200[/tex])

In one second the bus travels 25 yards, so; [tex]7200 * 25 = 180,000 yards[/tex]

Converting yards to miles is:  [tex]x (yards) / 1760[/tex]

[tex]180000/1760 = 102.2727272...[/tex]

∴ The bus will travel 102 miles in 2 hours.

A

Step-by-step explanation:

a. 4350 * 0.25 = 1087.50, food + transportation = 500 + 150 = 650, 650<1087.50, correct

b. 4350*0.5=2175, 1600 doesnt equal 2175, wrong

c. 4350 * 0.2 = 870, 500<870, wrong

d. 200<1087.50, wrong

Step-by-step explanation:

you multiply both the top and bottom by the root if it was alone.

let's say if we had (1 - sqrt(2)) in the denominator. here we multiply both the numerator and the denominator by the conjugate.

the conjugate is formed by changing the sign between two terms in a binomial. so in this case the conjugate is

(sqrt(2) -1)

Answer:

Option A

Step-by-step explanation:

Area of shaded region

Square:

   Side = 12 m

Area of square = Side *side

                        = 12 *12

                         = 144 square m

Circle:

  diameter = side of the square

                  = 12 m

             r    = 12/2

                r = 6 m

  Area of circle = πr²

                         = 3.14 *6 * 6

                         = 113.04 m²

Area of the shaded part = area of square - area of circle

                                        = 144 - 113.04

                                        = 30.96 m²

We can try for loops along with conditional statements to get the indices of the needed numbers.

Zero-based indexing indexes the elements of an array or such container starting from 0, instead of starting from 1 (which is what we usually do in real life).

For this case, assuming we want to write code in python, and array being simple list, plus we want the index of only first two numbers found which add up to the target, we have:

for idx_1 in range(len(arr)//2 + 2):

   num_1 = arr[idx_1]

   found = 0

   for idx_2 in range(idx_1 + 1, len(arr)):

       num_2 = arr[idx_2]

       if target == num_1 + num_2:

               print(idx_1, idx_2)

               found = 1

               break

   if found: break

Here we used 'range' function for first loop, which defaulty generates integers from 0, but can generate integers from whatever integer. Like in the second loop, it generates number from idx_1 + 1. Also, it doesn't include the last integer, given by the upper limit for the range.

This python code gives the indices of a pair of two numbers from the array given which adds up to the target.

Thus, we can try for loops along with conditional statements to get the indices of the needed numbers.

Answer:

161

Step-by-step explanation:

It's a system of equations, let's solve it step-by-step!

Equation: [3 * 2^5 + 13 * (-2)] + 7[8 - (4 - 9)]

2^5 = 32

so we have [3 * 32 + 13 * (-2)] + 7[8 - (4 - 9)].

3 * 32 = 96

so we have [96 + 13 * (-2)] + 7[8 - (4 - 9)].

13 * (-2) = -26

so we have [96 - 26] + 7[8 - (4 - 9)].

96 - 26 = 70

so we have 70 + 7[8 - (4 - 9)].

4 - 9 = -5

so we have 70 + 7[8 - (-5)].

8 - (-5) = 13 (the signs cancel out)

so we have 70 + 7[13].

7 * 13 = 91

so we have 70 + 91.

70 + 91 = 161

Therefore our answer is 161.

[tex]circumference = 2 \times \pi \times r[/tex]

[tex]circumference = 2 \times \pi \times 7[/tex]

[tex]circumference = 14\pi[/tex]

Answer:

14π

Step-by-step explanation:

Given:

To determine the circumference of the circle, we need to use the formula 2πr, where "r" represents the radius of the circle.

Substitute the radius in the formula:

[tex]\implies 2\pi (r) = \text{Circumference}[/tex]

[tex]\implies 2\pi (7) = \text{Circumference}[/tex]

Simplify the circumference:

[tex]\implies 2\pi (7) = \text{Circumference}[/tex]

[tex]\implies 14\pi = \text{Circumference}[/tex]

Thus, the circumference is 14π.

Answer:

(- 2, - 3 )

Step-by-step explanation:

y = 3x + 3 → (1)

y = x - 1 → (2)

substitute y = 3x + 3 into (2)

3x + 3 = x - 1 ( subtract x from both sides )

2x + 3 = - 1 ( subtract 3 from both sides )

2x = - 4 ( divide both sides by 2 )

x = - 2

substitute x = - 2 into either of the 2 equations and evaluate for y

substituting into (2)

y = - 2 - 1 = - 3

solution is (- 2, - 3 )

Answer:

y = -3, x = -2

Step-by-step explanation:

1. Substitute "y = x - 1" in for y in the first equation:

x - 1 = 3x + 3

2. Isolate x:

x = 3x + 3 + 1

3. Combine like terms:

-2x = 4

4. Solve for x:

-2x/-2 = 4/-2

x = -2

5. Solve for y with substitution (using the second equation):

y = -2 - 1

y = -3

The graph that represents the solution set for x > -6 is Graph D.

In mathematics, a number line is a straight line that represents numbers and their relative positions. It is a visual representation of the real number system.

To find the solution set for the inequality 2x + 3 > -9,

2x + 3 > -9

Subtract 3 from both sides:

2x > -12

Divide both sides by 2:

x > -6

The solution set for the inequality is x > -6, which means that x is greater than -6.

So, Among the given graphs, the graph that represents the solution set for x > -6 is Graph D.
