Answer:

1/100 to 25/100

or

0.01 to 0.25

Step-by-step explanation:

Pennies are also known as one per cent. Cent refers to 100 and pennies are called one per cent because they value 1 out of 100. 100 pennies equal one dollar.

Similarly, one quarter is 1/4 of a dollar and 1/4 equals 25/100 when multiplying the numerator and denominator by 25.

Answer:

Step-by-step explanation:

The function f(x)=x2 is not one-to-one because f(2) = f(-2). Its graph is a parabola, and many horizontal lines cut the parabola twice. The function f(x)=x 3, on the other hand, IS one-to-one. If two real numbers have the same cube, they are equal.

Answer:

1 and 1/10 from the school

3/5=6/10

1/2=5/10

6/10+5/10= 11/10

11/10=1 1/10

Solution :

It is given that the distance between the two lights is 30 feet.

The angle of elevation of the upper light from the boat, ∠ ABP = 32 degree

The angle of elevation of the lower light from the boat, ∠ ABQ = 14 degree

∴ ∠ PBQ = ∠ ABP - ∠ ABQ

              = 32 - 14

              = 18 degree

In triangle PAB

∠ PAB = 180 - (90 + 32)

           = 58 degree

Similarly in triangle AQB

∠ AQB = 180 - (90 + 14)

           = 76 degree

Now considering triangle PBQ and applying the sine theorem,

[tex]$\frac{PQ}{\sin 18}=\frac{BQ}{\sin 58}$[/tex]

we know PQ = 30 feet

∴ [tex]$BQ =\frac{\sin 58}{\sin 18} \times 30$[/tex]

        = 82.33 feet

Again taking the right triangle ABQ and applying sine theorem,

[tex]$\frac{BQ}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

[tex]$\frac{82.33}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

∴ [tex]$AB = 82.33 \times \sin 76$[/tex]

         = 79.88 ft

         = 80 feet

Step-by-step explanation:

here's your solution

=> x^2 + 15x + 50

=> By using middle term split

=> x^2 + 10x + 5x + 50

=> taking common from each

=> x(x + 10) + 5(x + 10)

=> (x + 5) (x + 10

Answer:

6x+2y=-78

Step-by-step explanation:

8x-3y=-70

-2x+5y=-8

6x+2y=-78

Answer:

(-11, -6).

Step-by-step explanation:

8x-3y=-70

-2x+5y=-8     Multiply this equation by 4:

-8x+20y=-32

Now add this last equation to the first equation:

17y = -102   - we see that we have eliminated x.

y = -102/17

= -6.

Now plug y=-6 in the first equation to get x:

8x-3(-6)=-70

8x =-70 -18

8x =-88

x = -11.

Answer:

6 Oranges and 2 bottles of juice.

Step-by-step explanation:

For the amount of oranges: 18÷3=6 (take 1/3 of 18).

For the bottles of of Juice: 18÷9=2 (take 1/9 of 18).

in this question, if the numerator is 1, then just divide the number of girls by the denominator (eg. 3 and 9 in this case).

There are six oranges and two bottles of juice will she needs for all 18 girls.

In mathematics, divides left-hand operands into right-hand operands in the division operation.

For example 4/2 = 2

There are the total number of girls is 18. Each girl will eat 1/3 of an orange and one serving of juice, or 1/9 of the amount in a bottle.

To determine the number of oranges and the bottles of juice.

We have to divide the number of girls by the denominator (eg. 3 and 9 in this case).

For the number of oranges:

1/3 of 18

18 ÷ 3

18 / 3 = 6

For the bottles of Juice:

1/9 of 18

18 ÷ 9

18 / 9 = 2

Hence, there are six oranges and two bottles of juice will she needs for all 18 girls.

Answer:

16

Step-by-step explanation:

(2 means squared) (c is the hypotenuse)

a2+b2=c2

a2+ (12×12) = (20×20)

a2+144=400

a2=256

a=16

Answer:

25% markup

Step-by-step explanation:

they bought 200 shirts for 1600, which is 8$ per shirt

if they sell then at 10$ they get 2 dollars profit.

if you do 2/8 you get 25%

Also 1/4 of 8$ is 2$ and that is what your profit is.

Answer:

25%

Step-by-step explanation:

Cost of one short:

1600 : 200 = $8

8 + 8(x/100)= 10

800 + 8x= 1000

8x = 200

x = 25 %

Answer:

AB = sqrt 74 = 8.602

Step-by-step explanation:

simple:

a^2+b^2=c^2

5^2+7^2=74

ab=sqrt 74

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(8−3)2+(2−9)2(8-3)2+(2-9)2

= √52+(−7)252+(-7)2

= √25+4925+49

= √7474 = 8.6023

Distance between points (3, 9) and (8, 2) is 8.6023

Answer:

y =  x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y =  x + 7 ← is in slope- intercept form

with slope m =

Parallel lines have equal slopes

line M crosses the y- axis at (0, 3) ⇒ c = 3

y =  x + 3 ← equation of line M
