Answer:

Lesley purchased 1 oval bead and 4 round beands.

Step-by-step explanation:

Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :

5 x 0.20 + 0 x 0.15 = 1

4 x 0.20 + 1 x 0.15 = 0.95

2 x 0.20 + 3 x 0.15 = 0.85

1 x 0.20 + 4 x 0.15 = 0.80

Therefore, Lesley purchased 1 oval bead and 4 round beands.

Equivalent expressions are expressions that have equal values

The equivalent expressions of [tex]y^{-8}y^3x^0x^{-2}[/tex] are [tex]x^{-2}y^{-5}[/tex] and [tex]\frac{1}{x^2y^5}[/tex]

The expression is given as:

[tex]y^{-8}y^3x^0x^{-2}[/tex]

Express x^0 as 1

[tex]y^{-8}y^3x^0x^{-2} = y^{-8}y^3 \times 1 \times x^{-2}[/tex]

Apply law of indices

[tex]y^{-8}y^3x^0x^{-2} = y^{-8 + 3}\times x^{-2}[/tex]

[tex]y^{-8}y^3x^0x^{-2} = y^{-5}\times x^{-2}[/tex]

Remove the product sign (x)

[tex]y^{-8}y^3x^0x^{-2} = y^{-5}x^{-2}[/tex]

Rewrite as:

[tex]y^{-8}y^3x^0x^{-2} = x^{-2}y^{-5}[/tex]

Rewrite as positive exponents

[tex]y^{-8}y^3x^0x^{-2} = \frac{1}{x^2y^5}[/tex]

Hence, the equivalent expressions of [tex]y^{-8}y^3x^0x^{-2}[/tex] are [tex]x^{-2}y^{-5}[/tex] and [tex]\frac{1}{x^2y^5}[/tex]

Answer:

y = (x² + 1) / (1 – x²)

Step-by-step explanation:

x = √[(y – 1)/(y + 1)]

We can make y the subject of the expression as shown below:

x = √[(y – 1)/(y + 1)]

Take the square of both side

x² = (y – 1) /(y + 1)

Cross multiply

x²(y + 1) = (y – 1)

Clear bracket

x²y + x² = y – 1

Rearrange

x² + 1 = y – x²y

Factorise

x² + 1 = y(1 – x²)

Divide both side by (1 – x²)

y = (x² + 1) / (1 – x²)

Answer:28.4

Step-by-step explanation:

Delta Math

The diameter of the asked hemisphere is 28.38 in.

The half of a sphere is called a hemisphere.

Given that, a hemisphere with a volume of 5990 in³

Volume of a hemisphere = 2/3πr³

2/3πr³ = 5990

r³ = 5990x7x3/22x2

r³ = 125790/44

r³ = 2858.8636

r = 28.38

Hence, The diameter of the asked hemisphere is 28.38 in.

area of rectangle (a1)=b×h

area of triangle=1/2 ×b×h

total area of arrow=a1+a2

Answer:

Step-by-step explanation:

You will find authentic some of the areas of 3 shapes, two of them are triangles, and one is rectangle.

The formula for calculating the area of right angle triangle is A= 1/2bh

The formula used to find the area of rectangle is A= W×L

A1+A2+A3

= 1/2b1h1+ 1/2b2h2+ W×L

1/2(10inches)(30inches)+ 1/2 (10 inches)(30 inches)+ (30 inches)(20 inches)

=150 inches²+ 150 inches²+ 600inches²

=900 inch²

Answer:

x = 7

x = 3

Step-by-step explanation:

(x - 5)² - 4 = 0

Take the (x - 5)² and foil it. By doing that, you're going to set them both against each other to multiply. The squared part means that (x - 5) is being multiplied by itself. Like so:

(x - 5) (x - 5)

Multiply the x by the x, the x by the -5, the -5 by x, and the -5 by -5.

The x times x would be x². The x times -5 would be -5x. The -5 times x would be -5x. And the -5 and -5 would be 25.

To put it in an equation: x² - 5x - 5x + 25 - 4

Simply the equation: x² - 10x + 21

Now that it's a quadratic equation, we can factor. Looking at the final term, the 21, we can find factors of 21 that add up to -10, which would be -7 and -3. They both multiply to a positive 21 and add up to a -10.

Taking this new information, we can split the equation up like so: (x -7), (x - 3)

Set both equations equal to 0.

So: x - 7 = 0

Add seven to both sides.

x = 7

x - 3 = 0

Add three to both sides

x = 3

Final Answer: x = 3, x = 7, both are real solutions

Answer:

slope=0

Answer:

87.2

Step-by-step explanation:

Answer:

46.6.

Explination:

99.2 - 6 is 93.2. 93.2 divided by 2 is 46.6.

A. 13

Step-by-step explanation:

What we are given....

∠A = 26° + x

∠B = 38° + x

∠A and ∠B are complementary

If complementary angles add up to equal 90° and ∠A and ∠B are complementary to each other

Then 26 + x + 38 + x = 90

                      ^ ( Note that we just created an equation that we can use to                              solve for x )

Now its just basic algebra

26 + x + 38 + x = 90

step 1 combine like terms

26 + 38 = 64

x + x = 2x

we now have 64 + 2x = 90

step 2 subtract 64 from each side

64 - 64 cancels out

90 - 64 = 26

we now have 26 = 2x

step 3 divide each side by 2

26 / 2 = 13

2x / 2 = x

we're left with x = 13
