A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 34
centimeters, and the length of the other leg is 24 centimeters. The student incorrectly says that the
length of the hypotenuse is 7.6 centimeters. Answer parts a and b.
a. Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.

Answers

Answer:

41.6 centimeters

Step-by-step explanation:

The right triangle formula: c^2 = a^2 + b^2

                                  c is the hypotenuse side of the triangle

                                  a and b are the legs of the triangle.    

 Find the hypotenuse :   c^2 = (24)^2 + (34)^2

                                          c = square root of (  (24)^2 + (34)^2)

                                          c = square root of ( 576 + 1,156)

                                          c = 41.6173

f(x) = 9x+7
find 20-3)

0 18c + 20
18c + 7
O -
180 - 20

Someone help?

Answers

Answer:

18c - 20

Step-by-step explanation:

substitute 2c - 3 into x,

f(2c - 3) = 9(2c - 3) + 7

=> f(2c - 3) = 18c - 27 + 7

=> f(2c - 3) = 18c - 20

The perimeter is the total distance of the sides of the rectangle. Since parallel sides in a rectangle are equal, we can calculate the perimeter using the length and width given. The area can be found by multiplying the length by the width.

(a)
Perimeter: 2l + 2w = 2(77 yd) + 2(24 yd) = 154 yd + 48 yd = 202 yd.

Area: 77 yd × 24 yd = 1848 yd².

———
(b) To determine how long it will take to walk around the field, one would need to know the total distance of the edges that make up the field. That would be the perimeter, which is the measure that would be used here.

(c) To determine the amount of turf needed to cover the field, one needs to know the size or extent of the surface of the region to be covered. That is the definition of area, which is the measure that would be used here.

What is the area of the classroom?
A. 36 m2
B. 48 m2
OC.-64 m2
OD. 72 m2

Answers

Answer:

64 m2

Step-by-step explanation:

12x6=72m2

2x4=8m2

72-8=64m2

The area for the given dimensions of Jared's classroom is, 64 m²

What is the area?

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Given that,

The dimensions of Jared's classroom are,

12 m, 4 m, 6 m, 4 m, 2 m, 8 m

we can divide the area of classroom in two parts,

first A₁, having side lengths of 6 m & 8 m

second A₂, having side lengths of 4 m & 4 m

Jared's classroom area =  A₁ +  A₂

A₁ = 6 × 8

      =  48

A₂ = 4 × 4

     = 16

A =  A₁ +  A₂

  = 16 + 48

  =  64

The area of classroom is 64 m²

Select ALL choices that are zeros of this function y=x2 +12x +32
​

Answers

Answer:

{-8, -4}

Step-by-step explanation:

Rewrite this function y=x2 +12x +32 as y = x^2 + 12x + 32; " ^ " indicates exponentiation.

Set this x^2 + 12x + 32 equal to zero (to find the zeros):  

x^2 + 12x + 32 = 0.  Let's solve this using the quadratic formula, which applies when ax^2 + bx + c = 0:

       -b ± √(b^2 - 4·a·c)

x = -------------------------------

                    2a

The coefficients of the given quadratic are {1, 12, 32}.  Thus, the discriminant is

b^2 - 4ac, or 12^2 - 4(1)(32), or 144 - 128, or 16. Therefore, we have:

       -12 ± √16                                                     -12 ± 4

x = --------------------    which simplifies to:    x = --------------- = { -8, -4}

              2                                                                  2

The zeros are {-8, -4}

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

mpho is the 50th fastest and slowest runner in her school.

Now,

Since, mpho is the 50th fastest and slowest runner in her school.

Hence, Total number of students = (50 + 50) - 1

                                                   = 100 - 1

                                                   = 99

Thus, There are 99 students in her school.

which of the at eight o'clock, which of is the angle between the hour and the minute hands

Answers

Answer:

At 8 o'clock angle between the two hands is 120 degree.

Step-by-step explanation:

For even hours, it’s easy. There are 12 numbers on the 360 degree clock face so each number is 30 degrees. Now, if you are after 6 then “the angle” is the other way so for 8:00, 12–8 = 4*30 = 120 degrees.

The problem comes in when you are not at an even hour. At, say, 8:20, the minute hand has moved 120 degrees and the hour hand has moved 1/3 of 30 or 10 degrees so, the angle is now 8*30 - 4*30 + 10 = 240 - 120 +10 = 130 degrees.

At 8:40 the minute hand has moved 8*30 = 240 degrees and the hour hand has moved 2/3 of 30 or 20 degrees so the angle is now 8*30 - 8*30 + 20 = 20 degrees
