There are only green yellow blue cubes in a bag

Answers

Answer 1

Answer:

1 ÷ 11

Step-by-step explanation:

The computation is shown below:

let us assume the yellow cubes be x

So, blue cubes be 2x

And, green cubes be 2x (4) 8x

Now the ratio is

Yellow: Blue: green

x:2x:8x

1:2:8

Now the probability of yellow cubes is

= 1 ÷ (1 + 2 + 8)

= 1 ÷ 11

How do I solve 2/3x-1=-3

Answers

first of all you’d add 1 to both sides hence the -1, to get 2/3x=-2. then multiply both sides by the reciprocal of 2/3 which is 3/2. the left cancels out to get x and the right multiplies to get -3. so your answer is x=-3

Answers

Answer:

y = 6/5x - 2 (or y = 1.2x - 2)

Step-by-step explanation:

To find the slope-intercept form ( = mx + b) you need to rearrange the equation of the line:

Step 1 - Add 18x to both sides

15y = 18x - 30

Step 2 - Divide both sides by 15.

How far away is the ladder from the house?
Round to the nearest tenth.

Answers

Answer:

1. 23.8

2. 7.7

Step-by-step explanation:

for the first blank

use sin because x is opposite and 25 is hypotenuse

set up an equation:

sin(72)= (x/25)

multiply both sides by 25:

25(sin(72))= (x/25)25

25(sin(72))= x

multiply 25 by sin(72):

23.8 = x

for the second blank

use cos because x is adjacent and 25 us hypotenuse

set up an equation:

cos(72)= (x/25)

multiply both sides by 25:

25(cos(72))= (x/25)25

25(cos(72))= x

multiply 25 by cos(72):

7.7= x

1. Let the side length of each small square on the grid represent 1 unit. Draw two different triangles, e. Ach with base 5 1/2 units and area 19 1/4 units2. 2. Why does each of your triangles have area 1914 units2?

Answers

Answer:

Step-by-step explanation:

Given that:

Each small square on a grid represents 1 unit

Base of triangle = 5 1/2 units = 11/2

Area of triangle = 19 1/4 unit² = 77/4

The Area, A of a triangle is obtained thus :

77/4 = 1/2 * 11/2 * h

77/4 = 11/4 * h

h = 77/4 ÷ 11/4

h = 77/4 * 4 /11

h = 7 units

Step-by-step explanation:

June was thinking of a number. June subtracts 5.6 from the number and gets an answer of 76.9. Form an equation with x from the information.

Answers

Answer: x - 5.6 = 76.9

Step-by-step explanation:

The number June thought of would give a result of 76.9 if 5.6 were subtracted from it.

Assume that number is x.

If you subtract 5.6 from x, you would get 76.9.

Equation is therefore:

x - 5.6 = 76.9

Solving for x would make x:

x - 5.6 = 76.9

x = 76.9 + 5.6

x = 82.5

abdel purchased a candy bar for $1.47 and ice cream for $3.48. How much change did he receive if he paid a ten-dollar bill.

Answers

1.47+3.48=4.95
10-4.95=5.05
Answer:
$5.05 is the change Abdel will receive if paid by a ten dollar bill.


Candy bar price plus ice cream price = the total amount / $3.48 + $1.47 = $4.95
Ten dollar bill subtracted by the total amount = the change / $10 - $4.95 = $5.05

A postcard has a perimeter of 20 inches. Its area is 21 square inches. What are the dimensions of the postcard?

Answers

Answer:

Length = 3 inches

Width = 7 Inches

Step-by-step explanation:

The shape of a postcard = Rectangle

L = Length

W = Width

A postcard has a perimeter of 20 inches.

Formula for perimeter of a rectangle = 2L + 2W

Hence:

2L + 2W = 20.... Equation 1

Its area is 21 square inches.

The formula for Area of a rectangle = LW

Hence:

LW = 21

L = 21/W

We substitute 21/W for L in Equation 1

2L + 2W = 20.... Equation 1

2(21/W) + 2W = 20

42/W + 2W = 20

Multiply both sides by W

42 + 2W² = 20W

2W² - 20W + 42 = 0

2W - 14W - 6W + 42 = 0

(2W - 6)( W - 7) = 0

2W - 6 = 0

2W = 6

W = 6/2 = 3

W - 7 = 0

W = 7 inches

Solving for L

L = 21/W

W = 7

L = 21/7

L = 3 inches

The dimensions of the postcard are:

Length = 3 inches

Width = 7 Inches

What is the equation of the line that passes through the point
(
7
,
2
)
(7,2) and has a slope of
1
1?

Answers

Answer:

(y+2)= -3(x-7)

Step-by-step explanation:

We can use the slope-intercept formula to write this equation. The slope-intercept form of a linear equation is:  

y = m x + b

 Where  m  is the slope and  b  is the y-intercept value.

We can substitute the slope into the formula giving:

y = − 3 x + b

Next, we can substitute the values from the points in the problem for  x  and  y  and solve for  b :

− 2 = ( − 3x 7 ) + b  

− 2 =  − 21 + b

21 − 2 = 21  − 21 + b

 19 = 0 + b

19 = b

We can now substitute the slope from the problem and the value for  b  we calculated into the formula to write the equation.

y = − 3 x + 19

Another process is to use the point-slope formula. The point-slope formula states:

 ( y − y 1 ) = m ( x − x 1 )

 Where  m  is the slope and  ( x 1 , y1 )  is a point the line passes through.

Substituting the slope and values from the points in the problem gives:

(y − − 2 ) = − 3 (x-7)

( y + 2 ) =  − 3 ( x − 7 )

A spaceship to the moon covered the 386,400 km in 72 hours. What was the average speed?

Answers

Answer:

289300 miles/72 hours * 1.60934 km/mile* 1 hour/3600 seconds = 1.48 km/second. Answer 6: To get average speed, we divide the total distance by the total time it takes to travel that distance. If we assume the distance to the moon is 238,900 miles then we divide by 72 hours to get roughly 3318 mph.

solve the right triangle (45-45-90)

Answers

Answer:

[tex]HI=HJ=\sqrt{30}[/tex]units

[tex]\angle I=45^{\circ}[/tex]

Step-by-step explanation:

We are given that

[tex]\angle J=45^{\circ}[/tex]

[tex]JI=2\sqrt{15}[/tex]units

We know that

[tex]sin\theta=\frac{Perpendicular\;side}{hypotenuse}[/tex]

Using the formula

[tex]sin45=\frac{HI}{2\sqrt{15}}[/tex]

[tex]\frac{1}{\sqrt{2}}\times 2\sqrt{15}=HI[/tex]

Where [tex]sin45^{\circ}=\frac{1}{\sqrt{2}}[/tex]

[tex]\frac{2\sqrt{15}\times \sqrt{2}}{\sqrt{2}\times \sqrt{2}}=HI[/tex]

By using rationalization

[tex]HI=\sqrt{30}[/tex] units

[tex]Cos45=\frac{HJ}{2\sqrt{15}}[/tex]

Using the formula

[tex]cos\theta=\frac{base}{hypotenuse}[/tex]

[tex]\frac{1}{\sqrt{2}}\times 2\sqrt{15}=HJ[/tex]

[tex]\frac{2\sqrt{15}\times \sqrt{2}}{\sqrt{2}\times \sqrt{2}}=HJ[/tex]

[tex]HJ=\sqrt{30}[/tex] units

When two sides are equal then angle made by two equal sides are equal

Therefore,

[tex]\angle J=\angle I=45^{\circ}[/tex]
