Answer : 34

Step-by-step explanation:

Solution,

Given,

base = 16

perpendicular = 30

hypotenuse = ?

Now,

By the formula of Pythagoras Theorem,

h^2 = p^2 + b^2

h^2 = 30^2+16^2

h^2 = 900+256

h = sqrt ( 1156 )

h = 34

Therefore, the value of x (hypotenuse) is 34.

4y -9x =-23 x=y-3 what is the y-value

Answers

Answer:

y = 10

Step-by-step explanation:

Use the substitution method since you already know what x equals.

4y - 9(y - 3) = -23

Simplify:

4y - 9y + 27 = -23

Combine like terms:

-5y + 27 = -23

Isolate y by subracting 27 from both sides:

-5y = -50

Divide by -5 to get y by itself:

-5/-5 = y

-50/-5 = 10

The hospital has found that if a patient is being visited on average at least 8.4 times per day, they can give the same patient care with 3 less nurse visits per day. How many nurse visits per day can the hospital reduce for these 13 patients?

Answers

Answer:

6

Step-by-step explanation:

the number of patients that get visted 8.4 times is 1 and another 1 at 8.3 add those up and mutiply by the 3 less nurses visits you get 6

Number of nurse hours  the hospital can reduce is 6.

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Number of patients visited on average at least 8.4 times per day = 2 patients

Now for each of the 2 patients the hospital can reduce 3 nurse visits.

Thus,

Number of nurse hours the hospital can reduce = 3 x 2

⇒ Number of nurse hours the hospital can reduce = 6 hours

Thus, Number of nurse hours  the hospital can reduce is 6.

25 POINTS!!! The equation y=470x represents the relationship between x, the time that a plane flies in hours, and y, the distance the plane flies in miles for plane A. The table represents the relationship for plane B. Find the slope of the graph for each plane and the plane's rate of speed. Determine which plane is flying at a faster rate of speed. Look at the photo.

Answers

Answer:

Step-by-step explanation:

For plane A,

Equation that represents the relationship between time 'x' and distance 'y' is,

y = 470x

By comparing this equation with the slope-intercept form of the equation,

y = mx + b

m = slope = 470

b = 0

Here, slope represents the speed of plane A.

Therefore, speed of plane A = 470 mi per hour

For plane B,

From the given table,

Slope of the graph = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

                                = [tex]\frac{960-480}{2-1}[/tex]

                                = 480

Speed of plane B = 480 miles per hour

Since, speed of plane B is more than plane A,

Plane B is flying faster.

The ration of child to teen to adult tickets sold at a water park on Saturday was 4:1:2. A total of 294 tickets were sold. How many child tickets were sold?

Answers

Answer:  168 child tickets were sold.

Step-by-step explanation:

Given: The ratio of child to teen to adult tickets sold at a water park on Saturday was 4:1:2.

Let the number of child tickets = 4x , teen tickets = x , adult tickets = 2x

Total tickets = x+4x+2x = 7x =294

[tex]\Rightarrow\ x=\dfrac{294}{7}\\\\\Rightarrow\ x=42[/tex]

Number of child tickets = 4(42) = 168

Hence, 168 child tickets were sold.
