Answer:

A.) 3m=r where M is the months he will read and R is the total number of books read.

B.) is 36 Because the equation is 3m=r you factor in the m as 12 because there are 12 months in a year. you get the new equation 3*12=R Finish the equation and you get 36=r

Answer:

7/8

Step-by-step explanation:

The value of c in cents when he bought 3 cakes for c cents and 2 loaves of bread for 2c - 11 cents each is 87 cents.

He buys 3 cakes that cost c cents each.

Therefore,

cost of the 3 cakes = 3c

2 loaves of bread that cost 2c - 11 cents each. Therefore,

cost of the two loaf of bread = 2(2c - 11) = 4c - 22

Hence, the total amount he spends can be represented as follows:

5.87 dollars = 587 cents

Therefore,

3c + 4c - 22  = 587

7c = 587 + 22

7c = 609

c = 609 / 7

c = 87

Step-by-step explanation:

V=1/3 πr²h

700 π=1/3 πr²×21

r²=100

r=√100=10 units

Answer:

r = 10

Step-by-step explanation:

Using the formula:

[tex]V = \pi r^{2} \frac{h}{3}[/tex]

We make r the subject to get:

[tex]r = \sqrt{3 \frac{V}{\pi h} }[/tex]

Now we substitute values given and simplify:

r = [tex]\sqrt{3 \frac{700\pi }{21\pi } }[/tex]

We can cancel out pi from top and bottom:

r = [tex]\sqrt{3 \frac{700 }{21 } }[/tex]

We can do 700÷21 = 33.3333333333

Now we have:

[tex]r = \sqrt{3 *33.3333333333}[/tex]
Simplify to get :

r ≈ 10

Answer:

Step-by-step explanation:

Angle 5 is opposite to 37 => It's equal to 37.
Angle 6 and 7 are supplementary to angle 5 => They are equal to 180 - 37 = 143 each.

Angle 4 is corresponding to Angle 7, and since the 2 lines are parallel, it's equal to 143.

Angle 1 and 3 is supplementary to Angle 4, so they are equal to 180-143 = 37 each

Angle 2 is opposite to Angle 4, so it's equal to 143.


Answer : Angle 1,3,5 = 37
Angle 2,4,6,7 = 143

Hello!

Let's solve this question by using elimination.

5x + 10y = 7

4x + 8y = 3

Let us solve for "y" first by making our "x" variables cancel each other out.

4(5x + 10y = 7)

-5(4x + 8y = 3)

20x + 40y = 28

-20x -40y = -15

0 = 13

Since both the "x" and "y" variables were canceled out after trying to eliminate one of the variables, we can't find a solution since we now have no variables to solve for, therefore there is no solution.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The figure of triangle is shown.

Here, The length of perpendicular distance = x mm

And, The hypotenuse = 178 mm

Hence, We get;

⇒ sin 34° = x / 178

⇒ 0.72 = x/178

⇒ x = 0.72 × 178

⇒ x = 128.2 mm

We know if we multiply 6x2=12 and 6x5=30. After 6 you can not multiply anything else higher than that. For example 15x2=30 but 15 is not a GCF of 12 and 4x3=12 3 and 4 are not GCFs of 30. So 6 is the GCF of 12 and 30.

Answer:

As with any function, the domain of a quadratic function f(x) is the set of x -values for which the function is defined, and the range is the set of all the output values (values of f ). Quadratic functions generally have the whole real line as their domain: any x is a legitimate input. The vertex will be the minimum (lowest point) of the graph if and the maximum (highest point) of the graph if

Answer:

The time it'd take for the element to have 15 g of mass is approximately 68 min.

Step-by-step explanation:

The radioactive decay of a substance is given by the following formula:

Since the element has a half life of 12 minutes, this means that after this time the mass of the element will be half of it was originally, therefore:

Therefore the mass of the element is given by:

If the initial mass is 760 g and the final mass is 15 g, we have:

The time it'd take for the element to have 15 g of mass is approximately 68 min.

Answer:

What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000

To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000

She used 29.8 feet of fencing for the fence -> The circumference of the circular garden is 29.8ft

Formula for circumference : 2πr

So, the radius is equal to : 29.8 : 2 : π = 4.74281730414... (round to 4.7)

Recheck : 4.7 x 2π = 29.5309709437... (close to 29.8)

The (2x,2y) column data is: A'=(-2,-6), B'=(-2,2), C'=(10,2) and D'=(10,-6). See the sketch of the (x,y) column and the (2x, 2y) column in the image 5.

The Cartesian graph presents x-axis (horizontal) and y-axis (vertical) that intercept in the origin (0,0). This type of graph is used to plot x and y coordinates.

The points, in the plane, are represented as (x,y).

Hence for your question:

A=(-1,-3) ⇒ -1 is x-coordinate and -3 is y-coordinate.

B=(-1,1) ⇒ -1 is x-coordinate and 1 is y-coordinate.

C=(5,1) ⇒ 5 is x-coordinate and 1 is y-coordinate.

D=(5,-3) ⇒ 5 is x-coordinate and -3 is y-coordinate.

For solving this question, you should plot the given points on a Cartesian graph.

      The result of this step you can see in the image 1.

         The result of this step you can see in the image 2.

         The result of this step you can see in the image 3. Now you see a rectangle.

       Thus, you should multiply x-coordinate and y-coordinate by 2.

       A=(-1,-3) ⇒ A'=(-2,-6)

       B=(-1,1)   ⇒ B'=(-2,2)

       C=(5,1)   ⇒ C'=(10,2)

       D=(5,-3) ⇒ D'=(10,-6)

       The result of this step you can see in the image 4.

         The result of this step you can see in the image 5. Now you see a new red rectangle with dimensions greater than the black rectangle plotted from (x,y) column.
