Answer:
C.) 2×10²
Step-by-step explanation:
(Sun dia) / (Mars dia) = (1.4 x 10⁶ km) / (0.7 × 10⁴ km) = (1.4/0.7) × 10²
The ratio of diameters is about 2 × 10².
_____
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
__
The diameter of Mars can be expressed several ways.
7000 = 7×1000 = 0.7×10,000 = 0.7×10⁴

The art room at a school is made up of 3 sections which are a pottery section a painting section and a sculpture section. Art work will be on display for an art show in all sections of the art room except the sculpture section, how much space is available for the art section ?
Answer:
2/3 or 66.6%
Step-by-step explanation:
Based on the information provided we see that there are a total of 3 sections that make up the entirety of the art room. Since the artwork will only be displayed on 2 sections out of the 3 that are available then there is 2/3 of the total amount of space available for the art section. In other words, only 66.6% of the art room is available for the art to be displayed on, while 33.3% is currently occupied and unavailable.
The sum of a number y and 9 is a least -1
Answer:
Y+9>= -1
Step-by-step explanation:
The sum of a number y and 9 means that we wanna add Y and 9, but since y is a variable and 9 is just a number, we can't add them.
Now we have Y+9
Now, we plug in our inequality sign which is at least.
at least is >=
Now we have Y+9>=
And all you have to do is place the negative one after the inequality sign, and you get Y+9>= -1
Hope this helps! :)

Answer:
What s your question?
Step-by-step explanation:
the school cafeteria is offering a choice of two side dishes at lunch today either watermelon or french fries the ratio of the number of orders of french fries to the total number of side dishes ordered is 9:14
A: there are 9 orders of french fries for every 14 orders of watermelon
B:there are 5 orders of watermelon for every 9 orders of french fries
C: there are 14 orders of french fries for every 9 orders of watermelon
D: there are 5 orders of french fries for every 9 orders of watermelon
Answer:
B
Step-by-step explanation:
Here, we are to select the best option that defines the ratio given in the question;
From the question, we are told that the ratio of french fries to the number of side dishes ordered is 9:14
Since 9 represents the french fries, then the ratio representing water melon orders will be 14-9 = 5
Hence, the ratio of french fries orders to water melon orders will be 9:5
The correct option is thus;
There are 9 orders of french fries for every 5 orders of watermelon
Or
There are 5 orders of watermelon for every 9 orders of french fries
Tell weather it is possible to draw a triangle with the given side lengths
a. 3 in, 4 in, 5 in.
b. 1 cm, 7cm, 8cm
c. 3ft, 5ft, 9ft
Answer:
The set of numbers 3 in, 4 in, and 5 in can form a triangle. a) is correct
Explanation:
A triangle is possible to be drawn only if the sum of the lengths of any two sides is greater than the length of the third side.
a) Is correct.
Testing all the posible combinations: 3+4>5, 4+5>3, 3+5>4. True. Hence, Option a is the correct choice,
b) Is incorrect
Since 1+7>8 is false, this choice is not correct
c) Is incorrect
Since 3+5>9 is false, this choice is not correct
5-4x=6+2x I need help right now SOMEBODY ANSWER STEP BY STEP PLZ HELP
Answer:
-1/6
Step-by-step explanation:
5-4x=6+2x
Add 4x to each side
5-4x+4x=6+2x+4x
5 = 6+6x
Subtract 6x from each side
5-6 = 6+6x-6
-1 = 6x
Divide by 6
-1/6 = 6x/6
-1/6 =x
Answer:
x = -1/6

Melinda made a scale model of an airplane. In the scale model, the length of the wingspan is 8 inches. The length of the wingspan of the actual airplane is 56 feet in length. Which scale did melinda usr to create the scale model of the airplane?
Answer: 1 inch =7 feet
Step-by-step explanation:
Scale factor = [tex]\dfrac{Image \ size}{original \ size}[/tex]
The length of the wingspan in model is 8 inches.
The length of the wingspan of the actual airplane is 56 feet in length.
Scale factor = [tex]\dfrac{56}{8}=7\text{ feet per inch}[/tex]
i.e. 1 inch of model gives 7 actual feet.
Required Scale: 1 inch=7 feet

Hernando ate StartFraction 2 Over 8 EndFraction of a pizza for a dinner. He gave his 6 friends the rest of the pizza and told them to share it equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below. StartFraction 6 Over 8 EndFraction divided by 6 = StartFraction (6 divided by 6) Over 8 EndFraction = one-eighth He concluded that each person received One-eighth of the whole pizza. Are Hernando's calculations correct? Explain why or why not. Yes, they are correct. Hernando divided 6 by 6. Yes, they are correct. Hernando divided Two-eighths by 6. No, they are not correct. Hernando should have multiplied by 6, not divided by 6. No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.
Answer:
Yes, they are correct. Hernando divided 6 by 6.
Step-by-step explanation:
Given that:
Hernando ate 2/8 of a pizza for dinner.
Let the pizza be x. Then:
Hernando ate [tex]\dfrac{2}{8} \ \ o f \ \ x[/tex]
Then he gave the rest of the pizza to his friends
Hernando now carried out the following calculations to support his activities;
[tex]\dfrac{6}{8} \div 6= \dfrac{6 \div 6}{8}= \dfrac{1}{8}[/tex]
[tex]\dfrac{6}{8} \times \dfrac{1}{6}= \dfrac{6 \div 6}{8}= \dfrac{1}{8}[/tex]
From the above calculation; we will see that Hernando divided 6 by 6 in both cases to get [tex]\dfrac{1}{8}[/tex].
Thus, the correct answer is:
Yes, they are correct. Hernando divided 6 by 6.
Answer:
A Yes, they are correct. Hernando divided 6 by 6. on edge
Step-by-step explanation:
hope this helps:)
