Answer 1

Answer: I believe it is D. Im sorry If I got you to fail

Answer 2

Answer:

B. 7/9 and 0.7

Step-by-step explanation:

Since 7 is inside the box that means 7 is being divided by 9 so 7/9, which eliminates C and D.

Since there are infinite more 0s in 7.000, there will be infinitely more 7s when you continue to try and divide. which means there must be a little line above the 7 in the 0.7, so the answer is B

Answers

Answer:

The correct option is;

The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects

Step-by-step explanation:

With the assumption that that the question meant that ΔACD and ΔBCD are congruent, we have;

Segment [tex]\overline {AC}[/tex] is congruent to segment [tex]\overline {BC}[/tex] by Congruent Parts of Congruent Triangles are Congruent, CPCTC

Similarly, segment [tex]\overline {DA}[/tex] is congruent to segment [tex]\overline {DB}[/tex] by Congruent Parts of Congruent Triangles are Congruent, CPCTC

Therefore, the points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects

$99 to $74 increase or decrease

Answers

Answer:

decrease, 25% percent change

Step-by-step explanation:

99 - 74 = 25 25 / 99 = 0.25 0. 25 × 100 = 25.25%

From $99 to $74, it is 25.25 percent decrease.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, $99 and $74.

From 99 to 74 it is decreased

Difference 99-74=25

Now, 25/99 ×100

= 0.2525×100

= 25.25%

Therefore, from $99 to $74, it is 25.25 percent decrease.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A salad dressing recipe calls for 3⁄4 cup of olive oil for every 1⁄2 cup of vinegar.

So, For 1 cup olive oil the vinegar used

= (1/2) / (3/4)

= 1/2 x 4/3

= 2/3 cup

Now, For 2 cups of Olive oil

= 2/3 x 2

= 4/3 Cups if Vinegar used.

Answers

Answer:

y= 1/4x -3

Step-by-step explanation:

point-slope form: y-y1=m(x-x1)

y-2=1/4(x-4)

y-2= 1/4x - 1

y= 1/4x - 3

The equation of a line in point-slope form with slope 1/4 and point (4, 2)

is y - 2 = (1/4)(x - 4).

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

The equation of a line is point-slope form is y - y₁ = m(x - x₁).

Given, Slope is 1/4 and has point (x₁, y₁) = (4, 2).

∴ The equation of the given line is y - 2 = (1/4)(x - 4).

A function is a relationship between inputs where each input is related to exactly one output.

f(2) = 194

f(3) = 291

Where f(x) is the calories burned.

x is the number of miles walked.

Yes, the given relation in the table is a function.

What is a function?

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Function:

Miles walk = input

Calories burned = output

We know that,

A function can have many-to-one and one-to-one.

A function can not have one-to-many.

Now,

From the table,

f(1) = 97

f(2) = 194

f(3) = 291

We see that the relation is a function.

The relation is a one-to-one relation.

Thus,

The given relation in the table is a function.

PLS revise and grammaratize asap plsHave you ever thought jellyfish were bad? Imagine a swarm of jellyfish came at you. What would you do? Jellyfish are becoming a concern; they are swarming fishing nets and affecting power plant pipes. These fish have reduced the number of fish and are clogging power plant pipes. These fish pose a threat to our economy, what will we do about it? The jellyfish has ruined fish harvesting and drastically decreased fish numbers. The jellyfish have affected the fish population and ruined the power plants. The jellyfish sting and harm the fish, so they are swarming the fish away. The jellyfish continue to clog the pipes in the power plants, so they are forced to shut down the plant. The fish have caused many problems for fishers and for power plant workers. The fish are dangerous and are becoming the pests of the ocean. The solution to some of these problems are to use some extra precaution and smaller nets. These fish are a harmful and pesty problem for today's Economy. The workers should not be the people to worry about the jellyfish. The major solution to this problem is to cut down on pollution. The reason for this is so the jellyfish have nothing to feed on. The reason for these swarms and clogging is because the jellyfish feed on the trash and pollution. These fish are a threat to our economy and are a danger to humans and animals. The jellyfish solution should be started immediately. The jellyfish problem should be solved soon because if it doesnt the jellyfish will take over. The jellyfish could continue to harm the fish and clog the power plant pipes.
