Answer:

In 30 days the rainfall level will be 30 × (2.3 +- 0.05 mm) or 69.0 +- 1.5 mm

Answer:

2.25

Step-by-step explanation:

A picture is 4 inches 6 inches long

The length at which it would be reduced to can be calculated as follows

6/x= 4/1.5

Cross multiply

4x= 9

x= 9/4

= 2.25

Hence the length would be reduced by 2.25

Answer:

6:18

Step-by-step explanation:

Answer:

About 8.5 hours

Step-by-step explanation:

Divide the total number of miles by the number of miles driven per hour. 470 divided by 55 is about 8.5, so it took her about 8.5 hours to get to the conference.

Answer:

x = 3   or  x = -2

Step-by-step explanation:

(x - 5)(x + 4) = [tex]x^{2} - x - 20[/tex] = -14

                      [tex]x^{2} - x -6 = 0[/tex]

                      (x - 3)(x + 2) = 0

                       x = 3   or  x = -2

Answer:

The correct end behavior are;

As x approaches positive infinity, y approaches positive infinity (D)

As x approaches negative infinity, y approaches positive infinity (B)

Step-by-step explanation:

Here, we want to get the end behavior of the graph

Kindly note that the upward arrow represents a movement toward infinity

Thus, we have it as follows;

As the value of x increases (towards the right); the value of y tends toward positive infinity

secondly: as the value of x decreases, tends toward the left, the value of y also tends toward positive infinity

Answer:

A

Step-by-step explanation:

The sides GH and FH are congruent, so Δ FGH is isosceles and the 2 base angles G and F are also congruent, then

∠ F = 65° → A

Answer:

x = 12

Step-by-step explanation:

10x+24 = 6x+72

10x - 6x = 72 - 24

4x = 48

x = 12

Answer:

144

Step-by-step explanation:

10x+24=6x+72

-6x          -6x

4x+24=72

     -24  -24

4x=48

/4   /4

x=12

<A=10(12)+24

<A=120+24

<A=144

Answer:

[tex]A=830\ ft^2[/tex]

Step-by-step explanation:

Given that,

The length of one base is 37 feet, and the length of the other base is 46 feet. The height is 20 feet.

We need to find the area of this section of the deck that is shaped like a trapezoid.

The area of a trapezium is given by :

[tex]A=\dfrac{a+b}{2}\times h[/tex]

a = 37 ft, b = 46 ft and h = 20 ft

Put all the values,

[tex]A=\dfrac{37+46}{2}\times 20\\\\A=830\ ft^2[/tex]

So, the area of this section of the deck is equal to [tex]830\ ft^2[/tex].

Answer:

Supplementary angles add to 180 degrees. So of the measure of the angle is x, the measure of its supplement is 2x. Angle = 60, supplement = 120

Step-by-step explanation:

Answer:

139.5º

Step-by-step explanation:

The sum of supplementary angles is 180º

s + 40.5 = 180

Subtract 40.5 from both sides

s = 139.5º

Answer:

3x^4-24x^3+72x^2-96x+48

Step-by-step explanation:

1. (x-2)^4

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

=x^4-8x^3+24x^2-32x+16

2. 3(x^4-8x^3+24x^2-32x+16)

=3x^4-24x^3+72x^2-96x+48

Answer:

Z'(9, - 1)

Step-by-step explanation:

For a 90 degree counterclockwise rotation about the origin,

The original coordinates of point P (x,y) will now be positioned as P' (-y,x).

Hence, given :

Triangle XYZ with X(-7,-9), Y(-10,-3), and Z(-1,-9)

The new position of Z denoted as Z' will be :

Z(-1, - 9) ; X = - 1 ; y = - 9

-y = - - 9 = 9

x = - 1 will remain as - 1

Z(-1, - 9) - - - > Z'(9, - 1)

The probability of drawing a red face card from a deck of cards is 3/26

Explanation:

In a deck of cards, there are 6 red-faced cards.

Probability = No. of favourable events / Total no. of events

So, the probability of drawing a red-faced card is 6 out of 52 cards.

Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.
