saniyah collected a total of 9 seashells she gave 1/3 to her sis how many seashells did Saniyah have left?

Answers

Answer: The answer is 3.

Step-by-step explanation: You would multiply 9x1/3 which would give you 3. If you want to understand even better here's how to do so: Put 3(the answer that you got from multiplying 9x1/3) into the fraction 1/3 as 1. In other words,  it would look something like this 3/3. Then, just multiply the two numbers 3x3 and that equals 9, the number you started with.

Hope that this helped!!:)

Considering the provided information in the given question, we have :

Total seashells Saniyah have = 9Number of seashells Saniyah gave to her sister = [tex]\sf \dfrac{1}{3} [/tex] of total.

We need to find how many seashells did Saniyah have left.

⇒ Number of seashells Saniyah have left = Total seashells – Number of seashells she gave to her sister

⇒ [tex] \sf {Left \: seashells = 9 - \Bigg \lgroup \dfrac{1}{3} \times 9 \Bigg \rgroup } [/tex]

⇒ [tex] \sf {Left \: seashells = 9 - \Bigg \lgroup 1 \times 3 \Bigg \rgroup } [/tex]

⇒ Left seashells = 9 – 3

⇒ Left seashells = 6

Therefore, Saniyah have left [tex] \bf {6 \: seashells } [/tex].

Based on these results, what is the probability that Kristie's spinner will land on Mexico the next time?

Answers

Answer:

3 / 10

Step-by-step explanation:

The required outcome = mexico ; number of spins = 6 spins

Total possible outcomes = sum. Of all spins = (6 + 4 + 5 + 5) = 20

P(Mexico on next spin) = required outcome / Total possible outcomes

P(Mexico on next spin) = 6 / 20 = 3 / 10

Answers

Answer:

the top wpuld be 73.14 and i cant see the numbers at the bottom

Step-by-step explanation:

The total surface area of the given figure which has cone and hemisphere is 944.08 square inches

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Let us find the height of the cone by using pythagoras theorem

7²+h²=15²

49+h²=225

Subtract 49 from both sides

h²=225-49

h²=176

h=13.2

Now let us find surface area of cone

A=πr(r+√(h²+r²))

A = 482.5

The surface area of hemisphere is 3πr²

A=3×3.14×(7)²

=3×3.14×49

=461.58

The total surface area = 482.5+461.58

=944.08 square inches

Hence, the total surface area of the given figure which has cone and hemisphere is 944.08 square inches

ABCD m angle ACD=2x+4 and m angle ACB=5x-5 . For what value of ABCD rhombus?


Please help quick ! This is a timed test

Answers

Answer:

I don't have a picture but since it is a rhombus, I'll give it my best shot.

IF those two angles are across from each other, they are equal, then:

2x+4 = 5x-5

add 5 to each side of the equation:

2x+9 = 5x

subtract 2x from each side:

3x = 9

divide both sides by 3:

x = 3

IF those two angles are adjacent, their sum is 180°, then:

2x+4 + 5x-5 = 180°

combine like terms:

7x - 1 = 180

add 1 to each side of the equation:

7x = 181

divide both sides by 7:

x = 25.86

Use the net to find the surface area of the prism.



96 in2

12 in2

24 in2

84 in2

Answers

Answer:

a. 96 in²

Step-by-step explanation:

The surface area of the prism = the sum of the area of each part of the net shown

✔️Area of the 2 equal triangles = 2(½*b*h)

b = 4 in

h = 3 in

Area of the two triangles = 2(½*4*3) = 12 in²

✔️Area of the rectangle 1 with the following dimensions:

L = 7 in

W = 3 in

Area = L*W = 7*3 = 21 in²

✔️Area of the rectangle 2 with the following dimensions:

L = 7 in

W = 4 in

Area = L*W = 7*4 = 28 in²

✔️Area of the rectangle 3 with the following dimensions:

L = 7 in

W = 5 in

Area = L*W = 7*5 = 35 in²

✅Surface area of the prism = 12 + 21 + 28 + 35 = 96 in²

Answer:

perimeter of square=4×side

perimeter of square =4×13cm

perimeter of square = 52cm

area of square = side²

area of square = (13cm)²

area of square = 169cm²

Answer:

52 cm / 169 cm²

Step-by-step explanation:

To find the perimeter, we can add together the lengths of all the sides. Since the height and width of the square are the same length, we can tell all four sides are equal.

13 + 13 + 13 + 13 = 52

The perimeter is 52 cm.

The area is the length times the width of the shape, so we have to multiply 13 by 13.

13 · 13 = 169

The area is 169 cm².

The answer is the third option, 52 cm / 169 cm².
