Answer:

shaded part = 116cm² (3sf)

Step-by-step explanation:

area of larger circle:  

a = πr²

  = π x 6.5cm²  

  = 132.7322896cm²

area of smaller circle:

a = πr²

  = π x 2.3cm²  

  = 16.61902514cm²

132.7322896 - 16.61902514 = 116.1132645

shaded part = 116cm² (3sf)

Hope this helps. :)

The shaded part of the circle is 116cm² (3sf)

How to find the shaded region?

To find a shaded region, First, take the area of the larger circle and the area of the smaller circle. Then subtract to find the shaded region.

Area of a larger circle:  

a = πr²

= π x 6.5cm²  

= 132.7322896cm²

Area of a smaller circle:

a = πr²

= π x 2.3cm²  

= 16.61902514cm²

= 132.7322896 - 16.61902514 = 116.1132645

Shaded part = 116cm²

The area of a circle is pi times the radius squared (A = π r²).

[tex]\frac{1}{48} \pi[/tex] units cubed

Step-by-step explanation:

The volume of a sphere is: [tex]\frac{4}{3}\pi r^{3}[/tex]

We know the radius r = 1/4, so we just plug this into the equation:

(4/3)*[tex]\pi[/tex]*(1/4)^3 = (4/3)*[tex]\pi[/tex]*(1/64) = [tex]\frac{1}{48} \pi[/tex]

So, the answer is  [tex]\frac{1}{48} \pi[/tex] units cubed.

Answer:

Step-by-step explanation:

[tex]volume=\frac{4}{3} \pi r^3\\=\frac{4}{3}\pi (\frac{1}{4} )^3\\=\frac{\pi }{48} ~units^3[/tex]

The TV is 27 inches tall.

Step-by-step explanation:

Given,

The diagonal length of the TV = 45 in

The width of the TV = 36 in

To find the length the the TV.

Formula

By Pythagoras theorem,

h²=l²+b², where h be hypotenuse, b be base and l be height.

Now,

Putting, h=45, b= 36 we get,

45²=l²+36²

or, l²= 45²-36²

or, l²= 729

or, l = √729

or, l = 27

Hence,

The TV is 27 in tall.

Answer:

13 divided by 6

Step-by-step explanation:

Final answer:

The situation where Chad is buying cupcakes and brownies with a budget of $13 is represented by the inequality 3x + 2y ≤ 13, where x is the number of cupcakes and y is the number of brownies.

Explanation:

To express Chad's purchasing situation at the bakery within his budget constraint in inequality form, we need to consider the cost per cupcake and brownie and how many of each he can buy without exceeding his budget of $13. Given that a cupcake costs $3 and a brownie costs $2, the inequality in standard form will reflect the price of each item multiplied by the quantity purchased.

The inequality representing this situation is 3x + 2y ≤ 13, where 'x' is the number of cupcakes and 'y' is the number of brownies. This inequality means that the total cost of cupcakes and brownies combined must not exceed $13, which corresponds to Chad's budget constraint.

Answer: Here we are going to use the equation y=15x2+3x+56.

x=0 in 2,000 so x=10 in 2010.  

Substitute 10 for x.

Answer:

her total is $140

Step-by-step explanation:

turn 12% into a decimal (0.12) then multiply that by the amount she paid (125*0.12) that gives you 15. then add 15 to 125 to get the total amount ($140)

hope this helps!

Answer:

$140

Step-by-step explanation:

The total before the 12% tip is $125

To find 12% of $125, we will change 12% to a decimal, 0.12

0.12 * 125=15

15$ is the tip.

125+15=140

Hi,

In a triangle, all angles must add up to 180*.

73 + 40 = 113

180 - 113 = 67

Thus, the measure of Z is equal to 67

Answer:

See below

Step-by-step explanation:

I see the term 2x being repeated 5 times, and repeated addition is multiplication, so we can do 5(2x) to get 10x, and we can set that equal to 11 to get 10x=11. Dividing both sides by 10 gets us x=11/10 or x=1.1

Answer:

No

Step-by-step explanation:

Sum the parts of the ratio, 2 + 3 + 5 = 10 parts

Divide 220 Kg by 10 to find the value of one part of the ratio.

220 Kg ÷ 10 = 22 Kg ← value of 1 part of the ratio, thus

2 parts = 2 × 22 = 44 Kg ← quantity of cement needed

3 parts = 3 × 22 = 66 Kg ← quantity of sand needed

5 parts = 5 × 22 = 110 Kg ← quantity of gravel needed

He has the required amounts of cement and sand but not of gravel.

Thus he cannot mix the concrete

Terry requires 44 kg of cement, 66 kg of sand, and 110 kg of gravel for the concrete mix. He has enough cement and sand but is short of gravel by 10 kg, so he cannot make the complete mix with the materials he currently has.

First, we calculate the total parts of the mix by adding the ratio numbers: 2 (cement) + 3 (sand) + 5 (gravel) = 10 parts in total. Next, we find out how much each part weighs: 220 kg ÷ 10 parts = 22 kg per part. Then we multiply the number of parts for each material by the weight per part: Cement needed = 2 parts × 22 kg/part = 44 kg, Sand needed = 3 parts × 22 kg/part = 66 kg, Gravel needed = 5 parts × 22 kg/part = 110 kg. Now, let's compare these requirements with what Terry has:

In conclusion, Terry does have enough cement and sand, but he does not have enough gravel for the mix.

Based on the choices provided, it appears that Sebastian used the information that 'The table shows two x-intercepts and it changes from increasing to decreasing' in his deduction. An x-intercept in a function table happens where the y-value equals zero. Two x-intercepts imply that there are two points where the function crosses the x-axis. A function's pattern shifting from an increasing pattern to a decreasing pattern is indicative of a maximum point. This suggests that Sebastian may be working with a quadratics or an inverted expressional function.

Answer:

616 cm²

Step-by-step explanation:

To find the area of a circle you use the formula A = π · r²

So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.

196 × (22/7) = 616

Answer:

616 square centimeters

Step-by-step explanation:

Diameter of circle = 28 centimeters

π = 22/7

Area of a circle, A = π [tex]\frac{D^{2} }{4}[/tex]

A =  [tex]\frac{22}{7}[/tex] * [tex]\frac{28^{2} }{4}[/tex]

A =  [tex]\frac{22}{7^{1} }[/tex] * [tex]\frac{(4 * 7)^{2} }{4}[/tex]

A =  [tex]\frac{22}{7^{1} }[/tex] *  [tex]\frac{4^{2} *7^{2} }{4}[/tex]

A = 22 * 28

A = 616 square centimeters

The real square roots of -121 are ±11i, where 'i' represents the imaginary unit.

When dealing with square roots of negative numbers, it's important to recognize that the square root of a negative number is an imaginary number. In this case, the square root of -121 is found by taking the square root of the positive value of 121 and then multiplying the result by 'i'. The square root of 121 is 11, so the square root of -121 becomes ±11i.

In the context of real numbers, square roots of negative values do not exist. However, in the realm of complex numbers, the introduction of the imaginary unit 'i' allows for the representation of square roots of negative numbers. The number 'i' is defined as the square root of -1. When squared, 'i' multiplied by itself yields -1.

Hence, the square root of -121, which is a negative number, results in ±11i, representing two imaginary numbers with opposite signs. These imaginary square roots are crucial in various fields, including mathematics, physics, and engineering, where complex numbers play a significant role in modeling and solving problems involving quantities with both real and imaginary components.
