Ms. Murray has a collection of 25 dimes and nickels. How many nickels does Ms. Murray have if she has a total of $2.30?

Answers

Answer 1
Answer: four nickels,
because 1 dime=10¢ and so 21 x .10 = 2.10 and 1 nickel=5¢ so .05 x 4 = .20

2.10 + .20 = 2.30

I’m not sure if the explaining made sense but it’s 4 nickels :)

Two cylindrical containers are shown. Container A has radius r and height h and holds a maximum of 42 ounces of water. Container B has radius r and height 1.5h. What is the maximum amount of water that Container B can hold?

Answers

Volume of a cylindrical container=πr²h
Container A:
πr²h=42 ounces of water.

Countainer B.
Volume of Container B=πr²(1.5 h)=1.5(πr²h)=1.5(42 ounces of water)=63 ounces of water.

Answer: the maximum amount of water that Container B can hold is 63 ounces of water. 

Triangle XYZ has been dilated to form triangle LMN. What is the least amount of information needed to prove the two triangles are similar?A.Two pairs of corresponding angles and one pair of corresponding sides

B.Two pairs of corresponding sides and one pair of corresponding angles

C.Two pairs of corresponding angles

D.Two pairs of corresponding sides

Answers

Answer:

Option C is correct.

Two pairs of corresponding angles

Step-by-step explanation:

Given triangle XYZ has been dilated to form triangle LMN.

Dilation states that it is a transformation that produces an image that is the same shape as the original, but of a different size.

therefore, the triangle XYZ  by a dilation is similar to triangle LMN

Similar figures have the

*same shape

*equal corresponding angle measures, and

*have proportional sides.

Therefore, the information which is needed to prove that two given triangles are similar is two pairs of corresponding angles

Two pairs of corresponding angles

Is 56/5, 21, 119/5 a right triangle?

I will mark the CORRECT answer Brainiest.

Answers

Answer:

Yes

Step-by-step explanation:

Step 1) Again - recall back to Pythagoras' Theorem: A^2+B^2=C^2 - when the squares of two of the sides of the triangle are equal to the square of the hypotenuse - then it is a Right Triangle.

Step 2) the equation will be written as such: (56/5)^2 + (21)^2 = (119/5)^2 and you render the exponents as: 125.44 + 441 = 566.44

Step 3) Add the numbers on the left: 566.44 = 566.44 - since the left equals the right, it is therefore a Right Triangle.

Name the shaded angle in three different ways

Answers

Answer:

1. "angle HGJ" or "angle JGH" (∠HGJ or ∠JGH)

2. "angle G" (∠G)

3. "angle 3" (∠3)

Step-by-step explanation:

Three ways the shaded angle can be named:

1. We can use capital letters to name the shaded angle. The middle letter indicates the vertex. Thus, we would name the shaded angle as: "angle HGJ" or "angle JGH". G is the middle letter, which indicates the vertex of the angle. Most often, the symbol "∠" is usually used to represent the word "angle". In short form, the shaded angle can be named as:

"∠ HGJ" or "∠ JGH"

2. The shaded angle can also be named according to the vertex. Thus, G is the vertex. The angle can be named "angle G" or "∠G"

3. Numbers can be placed at the vertex of the angle, and named accordingly. Thus, the shaded angle of which the vertex is labelled "3" can be named as "angle 3" or "∠3"

(6^4/12^4)^2 as a single power

Answers

Answer: 6^8 / 12^8

Step-by-step explanation:

To simplify the expression (6^4/12^4)^2 as a single power, you can use the properties of exponents.

First, simplify the numerator and denominator separately:

(6^4/12^4)^2 = (6^4/12^4) * (6^4/12^4)

Now, use the fact that (a/b)^2 = a^2 / b^2:

= (6^4 * 6^4) / (12^4 * 12^4)

Next, use the properties of exponents to combine the like bases:

= 6^(4+4) / 12^(4+4)

= 6^8 / 12^8

Now, you can simplify further by dividing both the numerator and denominator by a common power of 12 (in this case, 12^8):

= (6^8 / 12^8) / (12^8 / 12^8)

= (6^8 / 12^8) / 1

= 6^8 / 12^8

So, (6^4/12^4)^2 simplifies to 6^8 / 12^8 as a single power.
