Answer:

4/15

Step-by-step explanation:

1x4= 4

3x5=15

1/3 x 4/5 as a fraction is 4/15.

To find the product of fractions, you simply multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator.

Here's how you can apply this process to calculate 1/3 multiplied by 4/5:

Step 1: Multiply the numerators.

1 x 4 = 4

Step 2: Multiply the denominators.

3 x 5 = 15

Step 3: Combine the new numerator and denominator to form the product.

The product of 1/3 and 4/5 is 4/15.

Therefore, 1/3 x 4/5 = 4/15.

Therefore, 1/3 x 4/5 as a fraction is 4/15.

Answer:

128 ÷ 4 = [tex]\frac{128}{4}=32[/tex]

Step-by-step explanation:

Total number of photos = 128

Number of photo albums = 4

Alex has 128 photos of his friend to display equally in 4 photo albums.

Equation that can be used to find number of photos in each album =

Number of photo albums ÷ Total number of photos

= 128 ÷ 4

= [tex]\frac{128}{4}=32[/tex]

Step-by-step explanation:

Assuming the speed of car B to be x and the speed of car A to be x+20

156 = 208

x. x+20

156(x+20)= 208x

156x+3120=208x

3120=208x-156x

3120=52x

x=60

The speed of car A is (x)= 60

The speed of car B is(x+20)= 80

Answer:

[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]

Step-by-step explanation:

Multiply 4/3 to both sides to cancel out the 3/4 on the left.

Next, subtract 8 from both sides to cancel out the 8 on the left.

This should result in the equation x = 4!

Answer:

AC = 12

Step-by-step explanation:

From the question, we have that BD is perpendicular to AC

This means that it is at 90 degrees to the base

so we have two similar right triangles

Let us use Pythagoras’ theorem to get the measure of one of the legs (AD and DC)

Let us call the leg x

We have the Pythagoras’ theorem stating that the square of the hypotenuse (the side facing the right angle; 10 here) is equal to the sum of the squares of the two other sides

10^2 = x^2 + 8^2

100 = x^2 + 64

x^2 = 100-64

x^2 = 36

x = √36

x = 6

AD = DC = 6

AC = 2 * AD

AC = 2 * 6

AC = 12

Answer: ( -2, 7 )

Step-by-step explanation:

Solve 4x + y = -1 for y:

Add -4 to both sides:

4x + y + -4 = -1 + -4

y = -4x - 1

Now plug -4x -1 in the other equation with y:

-5x - 2 ( -4x -1 ) = -4

3x + 2 = -4

Add -2 to both sides:

3x + 2 - 2 = -4 + -2

3x = -6

Now divide both by 3:

3x/3 = -6/3

x = -2

Now plug in -2 in the first equation with x:

y = - 4 ( -2 ) - 1

y = 7

Answer:

A Bill le pagan $14 cada hora.

Step-by-step explanation:

Para conocer la cantidad que a Bill le pagan cada hora, se define una ecuación.

Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos. Es decir, una ecuación se define como una igualdad establecida entre dos expresiones, en la cual puede haber una o más incógnitas que deben ser resueltas.

En este caso, es conveniente definir la siguiente incógnita:

Si cada hora que trabaja Bill aparta $6 para dárselos a su mamá, entonces cada hora recibirá: x - 6

Bill trabaja 3 horas al día, por lo que en ese día recibirá 3horas*(x-6). Y si la cantidad total con que se queda cada día es $24, entonces la ecuación a resolver será:

3*(x -6)= 24

Resolviendo, obtienes:

3*x - 3*6= 24

3*x - 18= 24

3*x= 24 +18

3*x= 42

x= 42÷ 3

x= 14

Entonces, a Bill le pagan $14 cada hora.

Answer:

x=28

Step-by-step explanation:

Sum of all the angles in the triangle add up to equal 180

90 + x + 6 + 2x = 180

combine like terns

96 + 3x = 180

subtract 96 from each side

180-96=84

96-96 cancels out

3x=84

divide each side by 3

84/3=28

3/3 cancels out

x=28

=========================================

Explanation:

The quadrilateral shown is a kite since we have adjacent sides that are the same length (due to the similar tickmarks). The diagonals of any kite intersect to form a 90 degree angle.

The triangle in the lower left corner has the three angles of

Those three interior angles must add to 180. This is true of any triangle.

90+(x+6)+(2x) = 180

3x+96 = 180

3x = 180-96

3x = 84

x = 84/3

x = 28

Answer:

t = 36 minutes

Step-by-step explanation:

Given that,

Distance Andrea drive from home, d = 21 miles

The speed of Andrea, v = 35 mph

We need to find how many minutes will it take er to get to work. Let the time is t. We know that,

speed = distance/time

[tex]v=\dfrac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{21}{35}\\\\t=0.6\ h[/tex]

or

t = 36 min

So, the required time is 36 minutes.
