Answers

Answer 1

Answer: Another way of looking at it!

y

=

Explanation:

This is a ratio question in disguise.

By parts of the question:

"When y varies directly with x"

y

x

"if y=8 when x=4"

.

.

y

x

=

8

4

"how do you find y when x=5"

y

x

=

8

You count 100 chirps in 1 minute. What is the temperature?

Answers

Answer:

T = 50 + 100 - 40/4

T = 50 + 60/4

T = 50 + 15

T = 65

96 = 50 + x - 40/4

Subtract 50 from both sides:

46 = x - 40/4

Multiply by 4:

184 = x - 40

Add 40:

224 = x

Well, birds don't tend to like certain temperatures, and there seemed to be a lot of chirping, so I assume the temperature is the temperature a bird would like.

Answers

Answer:

2a²

Step-by-step explanation:

Pair 'like' terms with 'like' terms, ie numbers go with numbers, and 'a's go with 'a's.

Lets deal with the top of the fraction first:

4ax3a³

Rearrange it so you have numbers beside numbers and 'a's beside 'a's:

(4x3)x(axa³)

12x(a⁴) (because nᵃxnᵇ=nᵃ⁺ᵇ)

12a⁴

Now, instead of (4ax3a³)/6a², we have 12a⁴/6a²

First divide the numbers: 12/6 =2

Now divide the 'a' parts: a⁴/a²=a² (because nᵃ/nᵇ=nᵃ⁻ᵇ)

Now we have 2a²

Felicity’s dog eats no more than two cups of dog food per day. Felicity’s dog eats at least one-quarter cup more than one-half of the amount Martin’s dog eats. If the amount of food that Martin’s dog eats is represented by using m, which inequality represents the situation?
2 greater-than-or-equal-to one-half m + one-fourth
2 less-than-or-equal-to one-half m + one-fourth
2 + one-fourth greater-than one-half m
2 minus one-fourth greater-than one-half m

Answers

Answer:

2>_1/2m+1/4

Step-by-step explanation:

u

[tex]\frac{1}{4}+\frac{m}{2}[/tex] ≤ [tex]x[/tex] ≤ 2

[tex]x[/tex]  denotes amount of food that Felicity's dog eats.

What is inequality?

The mathematical expressions in which both sides are not equal are called inequalities. In inequality, unlike in equations, we compare two values. The equal to sign in between is replaced by less than, greater than or not equal to sign. Olivia is selected in the 12U Softball.


Given:

Felicity's dog eats no more than two cups of dog food per day.

Felicity's dog eats at least one-quarter cup more than one-half of the amount Martin's dog eats.

The amount of food that Martin's dog eats is represented by using [tex]m[/tex]

To find: the inequality that represents the situation

Solution:

Amount of food that Martin's dog eats = [tex]m[/tex]

Amount of food that Felicity's dog eats ≤ 2

Also,

Amount of food that Felicity's dog eats ≥  [tex]\frac{1}{4}+\frac{m}{2}[/tex]

Therefore,

[tex]\frac{1}{4}+\frac{m}{2}[/tex]  ≤ Amount of food that Felicity's dog eats ≤ 2

let [tex]x[/tex] denotes amount of food that Felicity's dog eats.

[tex]\frac{1}{4}+\frac{m}{2}[/tex] ≤ [tex]x[/tex] ≤ 2

Hence,  [tex]\frac{1}{4}+\frac{m}{2}[/tex] ≤ [tex]x[/tex] ≤ 2

[tex]x[/tex]  denotes amount of food that Felicity's dog eats.

Answer:

a. x is equal to the number of sweat shirts made

b. $1100 is I think the base cost it takes to produce shirts

c. x=30

d. $5845

hope I helped.

Step-by-step explanation:

a. context

b. if x=the number of sweat shirts made then 65×x means that it costs $65 to produce one shirt and in that case to make any shirts it would cost $1100 to get the process set up so that they can make the shirts.

c. if c(x)=3050 then that means that that is the total cost to make all the shirts they made at that time. We know x is the number of shirts and because of that we want to solve for x. to do that we need to isolate x, the first step would be to take 3050 and sub that into the first equation

3050=1100+65x

subtract 1100 from both sides

3050-1100=65x

1950=65x

divide both sides by 65

1950÷65=x

simplify

30=x

d. you take the equation at the top c(x)=1100+65x and sub in 73 for x.

1100+(65×73)

simplify

1100+4745=5845

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, The vertical or opposite distance is 2 feet and it has an angle of 5°.

∴ The horizontal or adjacent distance can be obtained by tan(theta).

Assuming horizontal distance to be x feet.

∴ tan(5°) = 2/x feet.

x = 2/tan(5°).

x = 22.9 feet.
