Answers

Answer 1

Answer:

D) [tex]1\frac{21}{40}m^2[/tex]

Step-by-step explanation:

We can first change the area of his garden into an improper fraction:

[tex]7\frac{5}{8} m^2 = \frac{61}{8}m^2[/tex]

Since Eric wants to split his garden into five equal sections, we divide the area of his garden by [tex]5[/tex]:

[tex]\frac{61}{8}\div 5 = \frac{61}{40}[/tex]

[tex]=1\frac{21}{40}m^2[/tex]

∴ The area of each new section is [tex]1\frac{21}{40}m^2[/tex]

Hope this helps :)

A plastic ball with a volume of 19.7
cm3 has a mass of 15.8 g. Would this
ball sink or float in a container of
gasoline (density of gasoline is 0.66-
0.69 g/cm3).

Answers

Answer:

as the density of the plastic ball is greater than the density of the gasoline it sinks

Step-by-step explanation:

D = 15.8 / 19.7

D = 0.80 g / c ^ 3

0.8> (0.66-0.69)

The density of the plastic ball is greater than the density of gasoline, the ball would sink in a container of gasoline.

Given that a plastic ball with a volume of 19.7 cm³ has a mass of 15.8 g.

We need to check if the ball sink or float in a container of gasoline if the density of gasoline is 0.69 g/cm³.

To determine whether the plastic ball would sink or float in a container of gasoline, we need to compare the density of the ball with the density of gasoline.

Density is defined as the mass of an object divided by its volume. In this case, the density of the plastic ball can be calculated as:

Density of ball = Mass of ball / Volume of ball

Given that the mass of the ball is 15.8 g and the volume is 19.7 cm³, we can calculate the density of the ball:

Density of ball = 15.8 g / 19.7 cm³

Density of ball ≈ 0.8 g/cm³

Now, we can compare the density of the ball with the density of gasoline, which is stated to be between 0.66 g/cm³ and 0.69 g/cm³.

Since the density of the ball (0.8 g/cm³) is greater than the density range of gasoline (0.66-0.69 g/cm³), the ball would sink in a container of gasoline.

y is inversely proportional to x. Given that y = 12 and x = 6. Find the value of y when x = 8.

Answers

Answer:

Step-by-step explanation:

formula for inverse proportion is y = [tex]\frac{k}{x}[/tex]

k is the constant of probability

to find k,

y is 12, x is 6

12 = [tex]\frac{k}{6}[/tex]

so x = 12 × 6

∴ k is 72

so y = [tex]\frac{72}{8}[/tex]

∴ y is 9

His weekly allowance would be $14 ; first you have to do 15-8= $7, because he got 8 dollars from cleaning the oven. Then you multiply the $7 by 2 because he had this much left after buying clothes, making his allowance twice as much, so 7 x 2= $14

Answer:

Step-by-step explanation:

250 for place 4 for books each.

If they charge 14 per person, 4 of that goes for the books and 10 will be applied to the rental fee.

250/10= 25 people to break even. Any people beyond that is a profit of 10.00 since the other 4 will still go to the books.

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?

Answers

The statement that best explains why Maricella's strategy is incorrect based on the distribution property and order of operation is option A.

Recall:

When given an equation involving brackets, the distribution property must be applied first which involves multiplying every term in a bracket by the term outside the bracket.

In the equation given, to solve for x, Maricella needs to apply the distribution property by using -2 to multiply each term in (3x - 4) and using +3 to multiply every term in (x + 1).

The next step will now be addition and subtraction of like terms.

Therefore, the statement that best explains why Maricella's strategy is incorrect based on the distribution property and order of operation is option A.

Marissa bought 4 cans of corn and 8 cans of green beans for a total of $7.00. Bob bought 8 cans of corn and 7 cans of green beans for a total of $8.60. Determine how much each can green beans cost.

Answers

Step-by-step explanation:

1 can of corn = c

1 can of green beans = b

Marissa-> 4c+8b=7

Bob-> 8c+7b=8.60

form a simultaneous equation:

4c+8b=7

8c+7b=8.60

find a common coefficient, e.g. make the number of cans of corn that Marissa has, equal to the number of cans of corn that Bob has, so you would multiply the top equation by 2, so both people have 8 cans of corn

8c+16b=14

8c+7b=8.60

now you can cancel out the cans of corn, and subtract the second equation from the first one, so you would get:

16b-7b=9b

14-8.60= 5.4

so, 9b=5.4, and b= 0.6

so 1 can of green beans would cost $0.60

Determine how (if possible) the triangles can be proved similar.

Answers

Answer:

It's not similar :)

hope this helps<3

The triangles are not similar because the sides are not proportional.

What are Similar Triangles?

Similar triangles are those triangles which has the same shape but different size.

The length of sides and angles are proportional in similar triangles.

So we know that length of sides are proportional.

If we find the ratio of corresponding sides of the two triangles, then they must be equal to a common value.

We have only the length of two sides of each triangle.

If those sides are proportional, we must have an angle of each triangle to be equal.

Here, the angles formed by the intersecting lines are vertical angles and are thus equal.

Let's look if the sides are proportional.

20 / 36 = 5/9

24 / 42 = 4/7

Sides are not proportional.

Hence the given triangles are not similar.
