Answer:

David's height is 57 inches.

Step-by-step explanation:

x/11=55

x=605

x/10=54.8

x=548

605-548=57

Answer:

57 inches

Step-by-step explanation:

undo the problem

55 x 11 = 605

54.4 x 10 = 548

605 - 548 = 57

hope I helped :)

Answer:

x=7

Step-by-step explanation:

since its a square, all sides are the same so 5x-11 = 6x-18 and then solve it :)

Answer:

x=15°

Step-by-step explanation:

We can see angle 6x-5 has a corresponding angle above it, which is congruent to it. That angle is supplementary with angle 7x-10. We can tell because it forms a straight angle with it. Supplementary angles add to 180°.

(7x-10)+(6x-5)=180

7x-10+6x-5=180

13x-15=180

13x=195

x=15

Answer:

56.73 ft

Step-by-step explanation:

Given:

51° (angle)

73ft (hypotenuse)

With the given information use sin to determine the height of the kite.

sin51° = x/73

solve for x (height)

x= 73*sin51°

x= 56.73ft

Answer:

115 degrees

Step-by-step explanation:

because a line is 180 degrees so you take 65 from 180 which gives you 115, and we know that thats the x on the top because the bottom line (which has 65 degrees) are the same with the top line (the one with the missing x) since the transversal line is evenly cut thru

Answer:

We reject H0 and conclude that local average time on the internet is

different from the national average

Step-by-step explanation:

H0 : μ = 6

H0 : μ ≠ 6

Test statistic :

(xbar - μ) ÷ (s/√(n))

(6.5 - 6) / (2 / √64)

0.5 / (2/8)

0.5 / 0.25

Test statistic = 0.5 / 0.25

Test statistic = 2

We obtain the Pvalue :

Using the Pvalue from test statistic (Z) score calculator :

Pvalue = 0.0455

α = 0.05

Since Pvalue < α ; We reject H0 and conclude that local average time on the internet is

different from the national average

4 or 2.5

Step-by-step explanation:

x+2x=3x

12/3=4=x

13+1=14

14/2=7=y

13+/-3=16/10

16/4=4

10/4= 2.5

this one depends wether 3 is negative or positive

The inequality the represents the expression -12d < - 6 is d < 1/2.

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign. Equations are not always balanced on both sides using a "equal to" sign in mathematics. Occasionally it might be about a "not equal to" connection, meaning that something is superior to or inferior to another.

The given inequality is -12d < - 6.

The inequality can be written as:

d < -6/ -12

d < 1/2

Hence, the inequality the represents the expression -12d < - 6 is d < 1/2.

there's really no explanation

Answer:

C) 25.13

Step-by-step explanation:

The formula for circumference is 2(pi)r.

In order to find r, or the radius, we can divide the diameter by 2.

d/2=r

8/2=4

r=4

Plug the radius into the formula

2(pi)4

And finally, plug it into your calculator.

2(pi)4 = ~25.13

Answer:

$50,000

Step-by-step explanation:

We have an average of 10 livestock units per hectare

The number of units in 250 hectares will be;

250 * 10 = 2,500 units

Amount earned per unit is $20 per year

So, for 2,500 units, we have

2500 * $20 = $50,000

Answer:

the radius of the sphere is 12 cm.

Step-by-step explanation:

IN A CONE

vertical height (h) = 27 cm

radius (r) = 32 / 2 = 16 cm

Now the volume of cone is

= 1/3 *h*π*r²

= 1/3 * 27 *π *16²

= 2304π cm³

Also by the question the cone and the sphere have equal volumes so

volume of sphere = volume of cone

                             = 2304 π cm³

OR, 4/3 πr³ = 2304 π

4/3 * r³ = 2304

r³ = 2304 * 3 / 4

r³ = 1728

r = ∛1728

r = 12 cm

So supplementary angles are ones that add up to 180degrees and complementary ones add up to 90degrees.

So for the left side, you find what angle is supplementary to the given one. For the angle of 35, another angle of 145 will add up to 180.

The right side want you to find the complementary angles, so for the angle of 18, another angle of 72 will add up to 90.

I always forget supplementary vs complementary, but a little bit of practice will help a lot.

Explanation:

There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.

If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.

The empirical probability of it not raining on the first of May is therefore...

1 - (probability it rains)

1 - (3/10)

(10/10) - (3/10)

(10-3)/10

7/10

We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.
