20% of what number is 18?

Answer:

no

Step-by-step explanation:

first you make the denominator the same:

2/5=6/15

2/3=10/15

2/5<2/3

or

2/3>2/5

Answer:

37.5%

Step-by-step explanation:

divide 9 by 24 and you get .375 abd then move 2 decimal places to the left to get a percentage

Answer:

Step-by-step explanation:

I know this is probably wrong but

I think she spends 37.8% of her day at work. 100% is the maximum for percentages. 100/24=about 4.2

9x4.2=37.8

Answer:

The ladder needs to be 26 ft long.

Step-by-step explanation:

So pythag is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]

We have the height and distance from the window, so we need to find c

[tex]10^{2}[/tex]+[tex]24^{2}[/tex]=[tex]c^{2}[/tex]

100+576= 676

[tex]\sqrt{676}[/tex] = 26

Answer:

-4<=x<=3

Step-by-step explanation:

the <= is greater or equal to but i dont have that on my key board

Answer:

-4 ≤ x ≤ 3

Step-by-step explanation:

Since it is a closed circle, x can be equal to -4 or 3 or any numbers in between

Answer:

(x+2)^2 - 6x+2

(x+2)^2 = (x+2).(x+2)

            = x(x+2) + 2(x+2)

           = xx + x2 + 2x +4 ( x2 = 2x)

           = x^2+ 4x +4

(x+2)^2 - 6x+2

x^2+ 4x +4- 6x+2

x^2+ 4x - 6x+2 +4

x^2- 2x+2 + 6 (b)

Answer:

3rd one

Step-by-step explanation:

[tex]sin = \frac{opposite}{hypotenuse}[/tex]

find sin f

the opposite of f is 96 and the hypotenuse is 100

so [tex]sinF=\frac{96}{100} or.96[/tex]

find sin g

the opposite of g is 28 and the hypotenuse is 100

so [tex]sinG=\frac{28}{100} or.28[/tex]

so your correct answer would be the third one

Answer:

[tex]x^{6}[/tex] + 1

Step-by-step explanation:

If exponents have the same base, then you could add the exponents together. The exponents have the same base of x.

4 + 2 = 6

[tex]x^{6}[/tex] + 1

Answer:

173

Step-by-step explanation:

supplementary means adding up the 2 angles make 180

7+173=180

Answer:

173 degrees

Step-by-step explanation:

Supplementary angles are angles that form 180 degrees. So subtract 7 from 180 to get the measure of the other angle (which would be 173 degrees).

Hope this helps!

s=30(3)/5

s=90/5

s=$18

Answer:

B

Step-by-step explanation:

An equation of a circle:

(x - a)² + (y - b)² = r²

(a; b) - a coordinates of a center

r - a radius

r = 5; P(6; 1) ⇒ a = 6 and b = 1

therefore

(x - 6)² + (y - 1)² = 5²

check:

A) Q(1; 11)

L = (1 - 6)² + (11 - 1)² = (-5)² + 10² = 25 + 100 = 125

R = 25

L ≠ R

B) R(2; 4)

L = (2 - 6)² + (4 - 1)² = (-4)² + 3² = 16 + 9 = 25

R = 25

L = R - CORRECT

C) S(4; -4)

L = (4 - 6)² + (-4 - 1)² = (-2)² + (-5)² = 4 + 25 = 29

R = 25

L ≠ R

D) T(9; -2)

L = (9 - 6)² + (-2 - 1)² = 3² + (-3)² = 9 + 9 = 18

R = 25

L ≠ R

Answer: B) R(2; 4).

Answer:

C. 748

Step-by-step explanation:

25 rows x 12 zucchini plants = 300 zucchini plants total

32 rows x 14 tomato plants = 448 tomato plants total

300 zucchini plants + 448 tomato plants = 748 plants total

Answer:

280 miles

Step-by-step explanation:

It is given that :

Scale : 1.25 inches = 50 miles

In the map the distance between Piedmont and Tulsa is = 3.5 inches

So the actual distance between Piedmont and Tulsa in miles is given by :

  1.25 inches = 50 miles

So, 3.5 inches = [tex]$\frac{50 \times 3.5}{1.25}$[/tex] miles

                       = 140 miles.

So when we go from Piedmont to Tulsa, it is 140 miles and we go back from Tulsa to Piedmont, it is another 140 miles.

Therefore, total distance = 140 + 140

                                         = 280 miles

Answer:

Step-by-step explanation:

for x then 4 = (x1+7)/2

8 = x1 + 7

1 = x1

for y then -3 = (y1+0)/2

-6 = y1

C = ( 1,-6 )

Answer:

Area of the remaining board = 403 cm²

Step-by-step explanation:

Area of the remaining paper board = Area of the rectangle - Area of the semicircle

Area of the rectangle = Length × Width

                                    = 28 × 20

                                    = 560 cm²

Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

                                     = [tex]\frac{1}{2}(3.14)(\frac{20}{2})^2[/tex]

                                     = 3.14 × 50

                                     = 157 cm²

Area of the remaining board = 560 - 157

                                                = 403 cm²

Answer:

10641.777 feets

Step-by-step explanation:

To obtain the distance to be traveled across the sea, we use trigonometry :

Cosθ = adjacent / hypotenus

Adjacent = 10000

Hypotenus = d

θ = 20°

Cos 20° = 10000 / d

0.9396926 = 10000 / d

d = 10000 / 0.9396926

d = 10641.777

The jet fighter will travel 10641.77 ft far across the sea.

It is given that angle of depression it land at is 20°.

It is required to find how far the sea will travel.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

We have an angle of depression = 20°

The height from the sea level = 10,000 ft

From the figure:

[tex]\rm cos20 = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\rm 0.939 = \frac{10000}{d}[/tex]

d = 10641.77 ft

Thus, the jet fighter will travel 10641.77 ft far across the sea.
