Leonora is incubating eggs. For the eggs to hatch, the temperature in the incubator (t) needs to be at least 77°F. Which statement represents the temperature it must be in the incubator for the eggs to hatch, in °F?

Answers

Answer 1

Answer: If the temperature is represented by variable T, the statement will be t ≥ 77°. Because the temperature can be greater or equal to 77°.

What is the answer to this problem... f(x)3x+7=

Answers

There really isn't a answer. Let me explain, this is a function. A function shows what operation you have to do to get a y value or any kind of value. Whenever it has a f(x) or any variable in the 'x' part you will automatically know that it's a function. So what you do is substitute any number for the variable that's there, any number, whether it's 100 or 1. So in this case a x is what we have to put in a substitute for. So let's try 1. 1x3 = 3, 3+7 is 10. So the function of x for 1 is 10. Now keep doing that and you'll get numbers which will turn into points in a graph (when we substituted in a 1 and got a result that's the y value) and that's the "answer".

Answer:

$m\angle M = 98\degree$

Step-by-step explanation:

As we know that:

Sum of the measure of all interior angles of a triangle is always 180°.

$\therefore (3x-16)\degree+(x+6)\degree+ x\degree = 180\degree\n\therefore (5x-10)\degree = 180\degree\n5x-10 = 180\n5x = 180 + 10\n5x = 190\nx= (190)/(5)\nx= 38\n\because m\angle M = (3x-16)\degree\n\therefore m\angle M = (3* 38 -16)\degree\n\therefore m\angle M = (3* 38 -16)\degree\n\therefore m\angle M = (114 -16)\degree\n\therefore m\angle M = 98\degree$

Find the value of the expression below for r = 4 and t = 2
t^3 - r + 20 divided by r

Answers

Answer:

The value of the expression $t^3-r+(20)/(r)$ is, 9

Step-by-step explanation:

Given: The expression $t^3-r+(20)/(r)$

Substitute the value of r=4 and t=2 in above expression to find its value;

$t^3-r+(20)/(r) = (2)^3-4+(20)/(4)$

Cube: the cube of a number t is its third power, the result of the number multiplied by itself twice. i.e, $t^3 = t * t * t$

Now, solve further we have;

$(2)^3-4+(20)/(4) = 8 -4+(20)/(4)$

Further, divide the number 20 by 4 we get the result 5 ;

⇒ 8-4+5 = 4+5 =9

Therefore, the value of the expression $t^3-r+(20)/(r)$ is, 9.

Your local minor League baseball team has 120 ball caps 180 miniature baseball keychains and 240 glow-in-the-dark bracelets to give away to the children on opening day the items will be split into identical sets with no items left over each child will receive one set of items. what is the greatest number of children that will receive a set of items on opening day please show all work due today

Answer:

greatest number of children that will receive a set of items on opening = 60

Step-by-step explanation:

We are told that local minor League baseball team has 120 ball caps 180 miniature baseball keychains and 240 glow-in-the-dark bracelets to give away to the children on opening day.

We are also told the items will be split into identical sets with no items left over.

Now, we want to find the greatest number of children that will receive a set of items on opening.

This implies that we have to find TH highest common factor of 120, 180 and 240

To do this, we will list out all the factors of each of the 3 numbers and then select the highest one that is common to the 3 of them.

Factors of 12 = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

Factors of 180 = 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

Factors of 240 = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240.

From all the factors listed above, the one that is the highest and appears in all three is 60

Thus, greatest number of children that will receive a set of items on opening = 60

Algebra help please!A high-speed train travels 480 km from Paris to Grenoble, France, at an average speed of 180 km/h. How long will it take to reach Grenoble?

A. 0.66 h

B. 3.8 h

C. 0.38 h

D. 2.7 h

Answers

To solve this you would use the equation, d=r*t. So you would take 480=180*t. Or you could use t=480/180. The answer would come out to 2.66 hours, which means the answer would round up to 2.7 hours. The answer would be D.
