Answer:

He should make the hypotenuse 5 in

Step-by-step explanation:

the pythagorean heoreom states that a^2+b^2=c^2. c is the hypotenuse. You already have a and b, 3 and 4. Plug it in

3^2+4^2=c^2

9+16=c^2

25=c^2

square root each side to isolate

c=5

Answer:

x ≈ 55.9°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{24}{29}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{24}{29}[/tex] ) ≈ 55.9° ( to 1 dec. place )

Step-by-step explanation:

factor the coefficients into primes

18 = 3 * 3 * 2

42 = 3* 2 * 7

- 12 = - 2 * 2 * 3

The primes that are underlined are 2 * 3 which is 6

The primes not in the brackets are what is inside the brackets.

Answer:

a=8

c=5.5

Step-by-step explanation:

solve simultaneously:

2a + 4c = 38.00

3a + 3c = 40.50

times the first eq. by 3 and the second by 2

6a + 12c = 114

6a +6c = 81

subtract from one another

6a + 12c = 114

-6a +6c = 81

6c = 33

c=5.5

3a + 3x5.5 = 40.50

3a= 24

a=8

Answer:

0.85c

Step-by-step explanation:

Given :

Discount on sale = 15%

Price of gift card at discounted price = c - 0.15c

Equivalent expression could be :

(100% - 15%) * price

Price = c

Answer:

x=9

JKL = 108 degrees

KLJ = 27 degrees

LJK = 45 degrees

Step-by-step explanation:

Add all the values of the triangle angles together to get 20. Then divide 180 by  20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).

JKL = 12x = 12(9) = 108

KLJ = 3x = 3(9) = 27

LJK = 5x = 5(9) = 45

Given:

A person on a moving sidewalk travels 24 feet the in 7 seconds.

The moving side walk has a length of 180 feet.

To find:

Time taken by the person to move from one end to the other.

Solution:

A person on a moving sidewalk travels 24feet the in 7 seconds.

The speed of the person is

[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]

[tex]\text{Speed}=\dfrac{24}{7}[/tex]

[tex]\text{Speed}=\dfrac{24}{7}[/tex]

The moving side walk has a length of 180 feet.

[tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]

[tex]\text{Time}=\dfrac{180}{\dfrac{24}{7}}[/tex]

[tex]\text{Time}=\dfrac{180}{1}\times \dfrac{7}{24}[/tex]

[tex]\text{Time}=52.5[/tex]

Therefore, the time taken by the person to move from one end to the other is 52.5 seconds.

Answer:

707 feet above sea level

Step-by-step explanation:

2 hours and 25 minutes is about 2.4167 hours.

Therefore:

y=8.77x+686

y=8.77(2.4167)+686

y=21.1944+686

y=707.1944

So the hiker's elevation will be approximately 707 feet above sea level

Answer:

Step-by-step explanation:

Example: Solve this triangle

right angled triangle 5 12 c

Start with: a2 + b2 = c2

Put in what we know: 52 + 122 = c2

Calculate squares: 25 + 144 = c2

25+144=169: 169 = c2

Swap sides: c2 = 169

Square root of both sides: c = √169

Calculate: c = 13

Given:

One midsegment of an equilateral triangle.

To find:

The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.

Solution:

All sides of an equilateral triangle are same.

Let a be the each side of the equilateral triangle.

Length of the midsegment is equal to the half of the non included side or third side.

[tex]Midsegment=\dfrac{a}{2}[/tex]

The sum of two side is

[tex]a+a=2a[/tex]

Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is

[tex]\text{Required ratio}=\dfrac{\text{Length of midsegment}}{\text{sum of two sides}}[/tex]

[tex]\text{Required ratio}=\dfrac{\dfrac{a}{2}}{2a}[/tex]

[tex]\text{Required ratio}=\dfrac{a}{4a}[/tex]

[tex]\text{Required ratio}=\dfrac{1}{4}[/tex]

[tex]\text{Required ratio}=1:4[/tex]

Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.

The required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk.
Let the total cost be t for the w walks.
So, the expression is given as,
t = 27w + 30

Where 27w represents the cost of w walks.

Thus, the required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

Answer:

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Step-by-step explanation:

Let be an exponential function of the form [tex]y = a\cdot b^{x}[/tex] that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex]. Then, we have the following system of equations:

[tex]20 = a\cdot b^{0}[/tex] (1)

[tex]720 = a\cdot b^{2}[/tex] (2)

By dividing (2) by (1), we obtain the value for [tex]b[/tex]:

[tex]\frac{720}{20} = b^{2}[/tex]

[tex]b = \sqrt{\frac{720}{20} }[/tex]

[tex]b = 6[/tex]

And the value for [tex]a[/tex] is found by (1):

[tex]a = 20[/tex]

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

easy y is 120

Answer:

1020 students

Step-by-step explanation:

We have the equation y = 0.1x + 18

If we have a school of 120 staff members, we can just set y = 120 and solve for the predicted total number of students, x.

120 = 0.1x +18

0.1x = 102

x = 1020 students

Answer:

55,000 milliliters

Step-by-step explanation:

So if washing machine uses 5 times more than dishwasher

Dishwasher: 11 litters of each cycle

Washing machine: 11 x 5= 55 litters for each machine in litters

If 1 litter is equal to 1000 milliliter then 55 x 1000 = 55,000 milliliters

FORMULA for milliliter: multiply the volume value by 1000
