What are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.?
*
P = 35 inches, A = 300 square inches
P = 70 inches, A = 300 square inches
P = 300 inches, A = 70 square inches
P = 35 inches, A = 200 square inches

Answer:

140.4ft^2

Step-by-step explanation:

since all four sides are equilateral triangles, you only need to find one triangle and multiply by 4.

area of triangle = 0.5×base×height = 0.5×7.8ft×9ft =35.1ft^2

surface area of pyramid= 35.2ft^2 × 4 = 140.4ft^2

The amount of water in Glass B to equal to 3 times of the amount water in Glass A

The volume is a measurement of three-dimensional space that is utilized.

Let r be the radius and h be the height of the cylinder and cone. Then the volume of the cylinder will be given as,

Volume of A = π r²h cubic units                       ...1

And the volume of the cone will be given as,

Volume of B = (1/3) × r²h cubic units       ...2

From equations 1 and 2

Volume of B = 3 x volume of A

The amount of water in Glass B to equal to 3 times of the amount water in Glass A

Answer:

yes it is possible

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Whenever you see a variable with an exponent (in parentheses) with another exponent (outside of the parentheses), you need to multiply them together.

[tex]2 \times 6 = 12[/tex]

Now that we only have b^4 x b^12, you might think we need to multiply the exponents again, but that would be wrong.

The only case where you should be multiplying exponents would be in the case of the first step.

Instead, we need to add them.

[tex] { b}^{4 + 12 = 16} [/tex]

Now we know our answer is C.

Answer:

B

Step-by-step explanation:

If you are not altering the triangle in any way and just moving it (translating), they should be the same size and shape. Thus, both triangles are similar (the same shape) and congruent (equal to each other)

Answer:

1, 000, 000

Step-by-step explanation:
There are 6 zeros, so add them to the 1.

The product of given numbers is 1,000,000.

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.

We need to find the product of 1000×1000.

Now, 1000×1000

= 1,000,000

Therefore, the product of given numbers is 1,000,000.

Answer:

I think it's the 2nd choice. Hopefully I got this correct :)

Step-by-step explanation:

I think you wrote that z will represent the number of hours spent babysitting but I think you meant x.

It's the 2nd choice because $30 is the flat rate for Julia and $10 is the flat rate for Kelsey. Julia has a rate of $5 per hour so that will be the number with the x. And Kelsey has a rate of $15 per hour so that will be the number with the x.

Julia: y = 5x + 30

Kelsey: y = 15x + 10.

Answer:

A. 35°

Step-by-step explanation:

Step 1: Derive an Equation

To answer this question, we will use what's called the Triangle Sum Theorem, which states that the sum of all of the interior angles of a triangle is 180°.

By this theorem, in ΔSRT (the triangle, not the angle), the sum of m∠TSR, m∠RTS, and m∠SRT is 180°. Putting this into a mathematical equation gives us the following:

m∠TSR + m∠RTS + m∠SRT = 180°

Now, from the picture, we can see that m∠TSR = 20° and m∠RTS = 125°. Substituting these values into our original equation gives us:

20° + 125° + m∠SRT = 180°

Step 2: Solve the Equation

Solving for m∠SRT, we get:

20° + 125° + m∠SRT = 180°

145° + m∠SRT = 180° (Simplify the LHS by combining like terms)

m∠SRT = 35° (Subtract 45° from both sides of the equation to isolate m∠SRT)

Answer:

[tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex]

Step-by-step explanation:

y= mx +c, where m is the slope and c is the y-intercept.

We need to find the value of m and c, which can be done by using the slope formula and by substituting a pair of coordinates respectively. Find m first before finding the value of c.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

[tex]slope = \frac{7 - ( - 4)}{5 - ( - 8)} [/tex]

[tex]slope = \frac{7 + 4}{5 + 8} [/tex]

[tex]slope = \frac{11}{13} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{11}{13} x + c[/tex]

Substitute a pair of coordinates:

When x= 5, y= 7,

[tex]7 = \frac{11}{13} (5) + c[/tex]

[tex]c = 7 - \frac{55}{13} [/tex]

[tex]c = \frac{91}{13} - \frac{55}{13} [/tex]

[tex]c = \frac{36}{13} [/tex]

[tex]c = 2 \frac{10}{13} [/tex]

Thus, the equation of the line is [tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex].

Step-by-step explanation:

Answer:

x = 37°

x = 40°

x = 260°

Step-by-step explanation:

To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.

Question 1

[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]

Question 2

To find the bigger arc, subtract the smaller arc from 360°

⇒ 360° - 140° = 220°

[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]

Question 3

The smaller arc can also be found by subtracting the external angle from 180°

Smaller arc = 180° - 80° = 100°

[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]

[tex]160^{\circ}=x-100^{\circ}[/tex]

[tex]x=260^{\circ}[/tex]

#1

#2

Bigger Arc=360-140=220°

#3

Smaller arc=180-80=100°
