What is the approximate probability that next years temperature ( year 16) will be in the 90s?

Answer:

x ≥ -15/2

Step-by-step explanation:

-2x - 4 ≤ 11

Add 4 to each side

-2x - 4+4 ≤ 11+4

-2x   ≤ 15

Divide each side by -2, remembering to flip the inequality since we are dividing by a negative

-2x/-2 ≥ 15/-2

x ≥ -15/2

Answer:

x≤-7.5

Step-by-step explanation:

-2x - 4 ≤ 11

Add 4 to both sides

-2x≤15/-2

Divide

x≤-7.5

Answer:

r = 1.0 cm to the nearest tenth

Step-by-step explanation:

The formula for the area of a circle of radius r is A = (pi)r².  So, from the given information we need to determine the radius of the orange.  The volume formula is V = (4/3)(pi)r³ and in this case V = 113.1cm³.  Thuis,

(4/3)(pi)r³ = 113.1cm³

                                                3                              3(113.1 cm³)

Multiplying both sides by ------------ , we get r³ = --------------------- , and so

                                              4(pi)                                12.57

r³ = 339.3 cm³ / 12.57 ≈ 0.997, so that r ≈ ∛(0.997 cm³) ≈ 0.9999, or

r = 1.0 cm to the nearest tenth.

Step-by-step explanation:

We know that tan=sin/cos, so tan(x+π/2)=

[tex]\frac{sin(x+pi/2)}{cos(x+pi/2)}[/tex]

Then, we know that sin(u+v)=sin(u)cos(v)+cos(u)sin(v),

so our equation is then

[tex]\frac{sin(x)cos(\pi/2)+cos(x)sin(\pi/2)}{cos(x+\pi/2)} = \frac{cos(x)}{cos(x+\pi/2) }[/tex]

Then, cos(u+v)=cos(u)cos(v)-sin(u)sin(v), so our expression is then

[tex]\frac{cos(x)}{cos(x)cos(\pi/2)-sin(x)sin(\pi/2)} = \frac{cos(x)}{-sin(x)} = -cot(x)[/tex]

C. (-3, -10)

Step-by-step explanation:

First label the 2 equations.

y=5x +5 -----(1)

x= -3 -----(2)

subst. (2) into (1):

y= 5(-3) +5

y= -15 +5 (expand)

y= -10 (simplify)

Thus, the answer is (-3, -10).

Answer:

THe answer is C

Step-by-step explanation:A

As seen by the last answer when we substitute the variable we can get (-3,-10)

x=-3------(2)

y=5x+5-----(1)

y=5(-3)+5

y=-15+5

y=-10

so (-3,-10) is the correct answer

Answer:

12

Step-by-step explanation:

1. Write out s+14=26

2. Subtract 14 by both sides to isolate s.

3. s = 12

Answer:

s = 12

Step-by-step explanation:

s + 14 = 26

  - 14   - 14         Subtract 14 from both sides

s = 12

Plug this back into the equation to make sure it works

12 + 14 = 26        Add

26 = 26               This solution does work

I got it right on the quiz.

We have been given that in triangle ABC angle A=45 angle B =40 and a=7. We are asked to find the equation that we can use to solve for 'f'.

We have two angles and opposite sides to these angles.

We will use Law of Sines to solve our given problem.

[tex]\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}[/tex], where a, b and c are opposite sides corresponding to angles A, B, and C respectively.

The angle opposite to side b is 40 degrees and angle opposite to side a is 45 degrees.

Upon substituting these values in Law of Sines, we will get:

[tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex]

Therefore, our required equation would be [tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex].

Answer:

total area of the garden and walkway = 2a² + 21a + 54

Step-by-step explanation:

The walkway surrounds the rectangular garden. The width of the garden is 9 ft and the length is 12 ft. Since the width of the walkway around the garden is the same on every side let us use a to represent the width around the garden.

The garden is rectangular and the width of the walkway around the garden is uniform. The width added on both end of the width of the rectangle will be 2a while the width added to the both length of the rectangle will be 2a also.

Therefore

total area of the garden and walkway = length × width

length of garden and the walkway = 2a + 12

width of garden and the walkway = 2a + 9

total area of the garden and walkway = (2a + 12)(2a + 9)

total area of the garden and walkway = 4a² + 18a + 24a + 108

total area of the garden and walkway = 4a² + 42a + 108

divide through by 2

total area of the garden and walkway = 2a² + 21a + 54

16. B

17. B

Step-by-step explanation:

Answer:

C; D; B; B

Step-by-step explanation:

14) 1/((1/4) + (1/7)) = 1/(11/28) = 28/11 (C)

15) 1/((1/x) + (1/3x)) = 3--> (1/x) + (1/3x) = 1/3 --> 4/3x = 1/3 --> x = 4 (D)

16) 56 - 28 = 28 --> 28/(4*2) = 3.5 hours --> 56/3.5 = 16mph (when adding the stream's speed)--> 16mph - 4mph = 12mph (B)

17) 540 - 480 = 60 --> 60/(9*2) = 10/3 hours --> 540/(10/3) = 162 (when adding the current) --> 162mph - 9mph = 153mph (B)

Answer:

umm is there something else we need to see

Answer:

Step-by-step explanation:

The problem states

Let's call [tex]x[/tex] one kilogram bananas and [tex]y[/tex] one kilogram oranges. The cost is related by

[tex]x=2y[/tex]

Also, we know by given

[tex]45x+30y=360[/tex]

Replacing the first equation into the second one, we have

[tex]45(2y)+30y=360\\90y+30y=360\\120y=360\\y=\frac{360}{120}\\ y=3[/tex]

Then, we find the other value

[tex]x=2(3)=6[/tex]

Therefore, one kilogram of oranges cost $3.

Answer: A ) She only used the additive inverse of 10m when combining like terms .

Step-by-step explanation:

Holly only used the additive inverse of 10m when combining like terms. The equality is erroneous because the equation was evaluated well. The calculations should be as follows:

11m -13n + 6mn - 10m + 7n - 3mn = 1m - 6n +3mn

She should have subtracted 13n and 7n then take the negative value. Also, subtract 6mn and 3mn.

Step-by-step explanation:

i took test

Answer:

a. 85.5 sq ft

b. 3 bottles

Step-by-step explanation:

a. The cardboard is rectangular in shape. How much he needs to paint is the same as the cardboard that he needs to paint.

The area of a rectangle is given as:

A = L * B

where L = length and B = breadth

Therefore, the area of the cardboard having dimensions 14 1/4 feet by 6 feet is:

A = 14 1/4 * 6

A = 57 / 4 * 6 = 85.5 sq feet

He needs to paint 85.5 sq feet of the cardboard.

b. On bottle of paint covers 40 sq feet. The number of bottles he will need for his backdrop will be the area he needs to paint divided by the amount of paint that can cover 40 sq feet:

85.5 / 40 =  2.14

Since the number of bottles he will need is a whole number and its greater than 2, then it must be 3.

To paint the entire cardboard, he must have 3 bottles of paint.

Answer:

75 feet

Step-by-step explanation:

The expression into an equivalent form [tex]5^{10} \times 5^5[/tex] is  [tex]5^{15}[/tex].

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need the expression into an equivalent form.

This expression could also be given by;

[tex]5^{10} \times 5^5[/tex]

Now plug the values then we get;

[tex]5^{10} \times 5^5\\\\= 5^{10+ 5} \\\\= 5^{15}[/tex]

Hence, the expression into an equivalent form [tex]5^{10} \times 5^5[/tex] would be; [tex]5^{15}[/tex]
