Answer:

The metric system is an alternative system of measurement used in most countries, as well as in the United States. The metric system is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurement, such as meter, liter, or gram.

The solution of the given inequality   c < - 36

Step-by-step explanation:

Explanation:-

Given inequality

               [tex]\frac{c}{9} < -4[/tex]

  Multiply '9' on both sides, we get

          [tex]9 X \frac{c}{9} < -4 X 9[/tex]

   ⇒   c < - 36

The solution of the given inequality   c < - 36

Answer:

15/70, first option

Step-by-step explanation:

if you multiply the numerators and denomenators together, you get 15/70. you're able to reduce this, but it looks like the answer doesn't want you to reduce it :)

=======================================================

Explanation:

We multiply the numbers across the top (numerator) to get 3*5 = 15

Then across the bottom (denominator), we multiply the values to get 10*7 = 70

So we get [tex]\frac{3}{10}\times\frac{5}{7} = \frac{3\times 5}{10\times7} = \frac{15}{70}[/tex]

That's how we end up with 15/70

------------------------------

Extra info:

Note how 15 and 70 have the GCF 5, so we can divide both values by 5

This means 15/70 reduces to 3/14; however, your teacher has decided not to reduce (since 3/14 is not one of the answers). So that means we should stick with 15/70 instead.

my class worked on this today im pretty sure its the first one!! good luck❤❤

Answer:

Step-by-step explanation:

The function f(x) = 10x + 50 models the total amount he has saved after 'x' months.

The domain is x-values, which is the number of the months.

x can only be zero or positive integers (since you can save after the month is complete), therefore the last option is correct.

Answer:

1/2

Step-by-step explanation:

1 3/4 is equal to 7/4.

7/4 times 2/7;

you can cancell to get rid of the sevens so it is 1/4 times 2/1

you can also cancel the two and convert the 4 to a two; 1/2 times 1

so the answer is 1/2.

Answer:

62.8

Step-by-step explanation:

To find the area of metal required, we calculate the area of the outer circle and subtract the area of the two inner semicircles. The area of the outer circle is,

AOC=πr2=π(62)=113.0973 in2

The area of the inner semicircles is,

AIC=2⋅12πr2=π(42)=50.26548 in2

The total area of the sign is,

A=113.0973−50.26548=62.83182 in2

Rounded to one decimal place, the area of metal required is 62.8 square inches.

The area of metal required is 62.8 square inches.

The area of a circle is the area covered by the circle in a two dimensional plane .

Area of the outer circle is,

=[tex]\pi[/tex]r²=[tex]\pi[/tex](6²)=113.04  square inches

The area of the inner semicircles is,

=[tex]\pi[/tex](4)²=50.24 square inches

The total area of the sign is,

=113.04−50.24=62.8 square inches

Hence, the area of metal required is 62.8 square inches.

Answer:

f = 3

Step-by-step explanation:

Given the equation cos(22f − 1) = sin(7f + 4), the following steps must be followed in order to get the value of f;

From the trigonometry identity, sin(90-theta) = cos theta.

cos(22f-1) = sin (90-(22f-1))

cos(22f-1) = sin (90-22f+1)

cos(22f-1) = sin (91-22f)... 3

substituting eqn 3 into the original equation given, we will have;

sin (91-22f) = sin(7f + 4)

91-22f = 7f+4

7f+22f = 91-4

29f = 87

f = 87/29

f = 3

Answer:

12

Step-by-step explanation:

Answer:12

Step-by-step explanation:

Solution for What is 60 percent of 20:

60 percent * 20 =

(60:100)* 20 =

(60* 20):100 =

1200:100 = 12

Now we have: 60 percent of 20 = 12

Question: What is 60 percent of 20?

Percentage solution with steps:

Step 1: Our output value is 20.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$20=100\%$.

Step 4: Similarly, $x=60\%$.

Step 5: This results in a pair of simple equations:

$20=100\%(1)$.

$x=60\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{20}{x}=\frac{100\%}{60\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{20}=\frac{60}{100}$

$\Rightarrow x=12$

Therefore, $60\%$ of $20$ is $12$

The sides of which diagram are correctly labeled with respect to angle A is Figure II.

Sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec) are the six trigonometric ratios . A branch of mathematics called trigonometry in geometry deals with the sides and angles of a right-angled triangle. Trig ratios are therefore assessed in relation to sides and angles.

Trigonometric ratios are based on the value of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions. The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.
