The tape diagram represents the ratio of the numbers of planets in two different solar systems. There are 8 planets in Solar System B. How many planets are in Solar System A?
Answers
The correct answer is 6 planets
Explanation:
The image presented shows the ratio of planets in solar system A vs those in solar system B. In this way, the general ratio is 3 : 4 or 3 to 4; this means for each 4 four planets in solar system B there are 3 planets in solar system A and vice versa. Now, to find the total of planets in system A if there are 8 planets in system B, follow this process:
8 planets / 4 = 2 planets - This means each of the sections in the diagram represents 2 planets
2 section x 3 = 6 planets as in the solar system A there are 3 sections and each of this represents 2 planets, the total of planets in this system are 6
This result can also be found by converting the ratio to a fraction and multiplying this by the 8 planets
8 planets x [tex]\frac{3}{4} = \frac{24}{4} = 6[/tex]
At 8:00 am, the temperature was -10°F. The temperature dropped 3 degrees per hour for the next 5 hours. What was the temperature at 1:00 pm?
Answers
Answer:
-25 °F
Step-by-step explanation:
First, we would be multiply 3 by 5 to find the number we would be subtracting from the original
3 * 5 would give us 15
Then we subtract -10 by 15 and get -25 °F
The temperature at 1:00 PM would be -25 °F

Answer:
[tex]\boxed {x = 4}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]7x - 21 = x + 3[/tex]
-Take [tex]x[/tex] and subtract it from [tex]7x[/tex]:
[tex]7x - 21 - x = x - x + 3[/tex]
[tex]6x - 21 = 3[/tex]
-Add both sides [tex]21[/tex]:
[tex]6x - 21 + 21 = 3 + 21[/tex]
[tex]6x = 24[/tex]
-Divide both sides by [tex]6[/tex]:
[tex]\frac{6x}{6} = \frac{24}{6}[/tex]
[tex]\boxed {x = 4}[/tex]
Thus, the value of [tex]x[/tex] is [tex]4[/tex].

A ladder is placed against a wall such that the top is 8 feet above the ground. If the ladder is 10 feet long, how far away from the wall is the base of the ladder
Answers
Answer:
6 feet
Step-by-step explanation:
Consider the right triangle formed by the wall, ladder and ground.
Let the distance the ladder is from the wall be d , then
Using Pythagoras' identity in the right triangle
The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then
d² + 8² = 10²
d² + 64 = 100 ( subtract 64 from both sides )
d² = 36 ( take the square root of both sides )
d = [tex]\sqrt{36}[/tex] = 6
That is the ladder is 6 feet away from the wall
1/2 (2y-6) = 24
1/4 (4-y) = 10 + 24
2 (2y-3) = 4y-6
