Answer:

132.4m^2

a) 1/8(1/6)= 1/48

b) 1/2(1/8)= 1/16

c) 1/4(1/3)= 1/12

A) 2/45

B) 1/45

C) 1/30

D) 1/15

E) 2/15

F) 4/45

Step-by-step explanation:

1) 6.2m(12m)= 74.4m^2

10m(5.8m)= 58m^2

74.4m^2 +58m^2= 132.4m^2

2)

a) 1/8(1/6)= 1/48

b) 1/2(1/8)= 1/16

c) 1/4(1/3)= 1/12

3)

a) 4/10(1/9)= 4/90= 2/45

b) 2/10(1/9)= 2/90= 1/45

c) 3/10(1/9)= 3/90= 1/30

d) 3/10(2/9)= 6/90= 2/30= 1/15

e) 4/10(3/9)= 12/90= 4/30= 2/15

f) 2/10(4/9)= 8/90= 4/45

Find the value of X.
andriy [413]

Answer:

x=3

Step-by-step explanation:

All the angles added together must equal 360 degrees.

74+43+50+37+12x+12x+11x+17x = 360

Simplify the equation by adding like numbers.

204+52x=360

Subtract 204 from both sides of the equation.

204+52x-204=360-204

52x=156

Now, divide both sides by 52.

52x/52=156/52

x=3

tyra has 12 2/3 cups of sugar. if r is the amount of sugar needed for one batch of cookies, the expression 12 2/3 ÷ r can be use
olga nikolaevna [1]

ANSWER

She can make 19 batches of oatmeal.

EXPLANATION

First we can change the mixed number into an improper fraction:

12\frac{2}{3}=12+\frac{2}{3}=\frac{12\cdot3}{3}+\frac{2}{3}=\frac{36}{3}+\frac{2}{3}=\frac{38}{3}

In this problem, r = 2/3. The division is:

12\frac{2}{3}\div r=\frac{38}{3}\div\frac{2}{3}

Using the KFC rule:

\frac{38}{3}\div\frac{2}{3}=\frac{38}{3}\times\frac{3}{2}

Solving we can see that the denominator of the first fraction can be simpliied with the numerator of the second fraction:

\frac{38}{3}\times\frac{3}{2}=\frac{38}{1}\times\frac{1}{2}=\frac{38}{2}=19

Tyra can make 19 batches of oatmeal with 12 2/3 cups of sugar.

Where is the hole for the following function located?
Drupady [299]

<em>At x = -3 is located a hole. </em>

<h2>Explanation:</h2>

In this problem, we have the following function:

f(x)=\frac{x+3}{(x-4)(x+3)}

A hole will lie at the x-values that makes the function undefined, that is, when the denominator is zero. In a mathematical language:

(x-4)(x+3)=0

From this equation, we get two solutions:

x=4 \\ \\ x=-3

At those x-values the function will have a hole. From the choices:

<em>At x = -3 is located a hole. </em>

A circle has a radius of 3. An arc in this circle has a central angle of 20°
Alla [95]

Answer:

The length of the arc is 1.0467

Step-by-step explanation:

First of all to solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 3

π = 3.14

c = 2π * r

we replace with the known values

c = 2 * 3.14 * 3

c = 18.84

The length of the circumference is 18.84

Now we have to divide the 20° by the 360​​° that a circle has, to know what part of the circle it represents

20° / 360° = 1/18

Now we multiply this fraction by the circumference and obtain the length of the arc

1/18 * 18.84 = 1.0467

The length of the arc is 1.0467
