Answer:

7.99- no

8.162- no

8.074- yes

8.13- yes

8.012- no

Step-by-step explanation:

7.99 to the nearest tenth = 8.0

8.162 to the nearest tenth= 8.2

8.074 to the nearest tenth=8.1

8.13 to the nearest tenth=8.1

8.012 to the nearest tenth=8.0

When rounding to the nearest tenth look at the place after it. If it is less than five then the number in the tenth will be rounded to 0. However if the following digit is 5 and above, 1 is added to the number you are rounding.

Answer:

x = 5, -4

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

Answer:

x = 5, x = -4

Explanation:

Solve with the quadratic formula

[tex]x_{1,2} =\frac{-(-1)+-\sqrt{(-1)^2-4*1*(-20)} }{2*1}[/tex]  =  [tex]x_{1,2} = \frac{-(-1)+-(9)}{2*1}[/tex]

Separate the solutions

[tex]x_1 = \frac{-(-1)+9}{2*1} , x_2 = \frac{-(-1)-9}{2*1}[/tex]

[tex]x_1 = 5\\x_2 = -4[/tex]

Answer:

[tex]w + \frac{5}{6} t - \frac{2}{3} r[/tex]

Step-by-step explanation:

[tex] \frac{2}{3} w + \frac{5}{6} t + \frac{1}{3} w - \frac{2}{3} r[/tex]

[tex] \frac{2}{3} w + \frac{1}{3} w = \frac{2w}{3} + \frac{1}{3} w[/tex]

[tex] \frac{2w}{3} + \frac{w}{3} = \frac{2w + w}{3} [/tex]

[tex] \frac{3w}{3} = w[/tex]

[tex] = w + \frac{5}{6} t - \frac{2}{3} r[/tex]

n(AUB)=n(A)+n(B)-n(AnB)

=25+27-10

=52-10

=42

n(AUB)=n(A)+n(B)-n(AnB)

=25+27-10

=52-10

=42

The formula for the number of elements in A union B is n(A U B) = n(A) + n(B) - n(A ∩ B).

What is AUB A ∩ B?

The union of two sets A and B, written A U B, is the combination of the two sets. Intersection The intersection of two sets A and B, written AnB, is the overlap of the two sets.

Answer:

9.6 square inches.

Step-by-step explanation:

We are given that ΔBAC is similar to ΔEDF, and that the area of ΔBAC is 15 inches. And we want to determine the area of ΔDEF.

First, find the scale factor k from ΔBAC to ΔDEF:

[tex]\displaystyle 5 k = 4[/tex]

Solve for the scale factor k:

[tex]\displaystyle k = \frac{4}{5}[/tex]

Recall that to scale areas, we square the scale factor.

In other words, since the scale factor for sides from ΔBAC to ΔDEF is 4/5, the scale factor for its area will be (4/5)² or 16/25.

Hence, the area of ΔEDF is:

[tex]\displaystyle \Delta EDF = \frac{16}{25}\left(15\right) = 9.6\text{ in}^2[/tex]

In conclusion, the area of ΔEDF is 9.6 square inches.

Answer:

the play area is a circle with radius = 12

Step-by-step explanation:

Circle area = A= π r²

r = radius

A = 144 π = 452.39

Diameter = 2r

= 24

circumference = C = 2π r

= 24 π = 75.4

Q2)

Area = π r²

r = 15

r²= 225

area = 706.5

Answer:

the answer will be 4x²...last option

Answer:

Answer is 4x² = 36

Step-by-step explanation:

Let that number be x:

[tex]4 \times x {}^{2} = 36 \\ {4x}^{2} = 36[/tex]

further more:

[tex] {x}^{2} = \frac{36}{4} [/tex]

take a square root:

[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{36}{4} } \\ \\ x = \frac{ \sqrt{36} }{ \sqrt{4} } \\ \\ x = \frac{6}{2} \\ \\ x = 3[/tex]

Answer:

c = -25

Step-by-step explanation:

1. 23 - 6c = 48 - 5c

(add 5c to both sides)

2. 23 - c = 48

(subtract 23 from both sides)

3. -c = 25

(divide by -1 to both sides)

c = -25
