Answer:
73%
Step-by-step explanation:
if 100% of the skittles are there, and 27% are red, then you would just subtract to find out how many aren't red.
100-27=73
Rewrite the equation 3r - 6 = 39 by factoring the side that contains the variable r. Pls help
Answer:
r=15
Step-by-step explanation:
you would add 6 to the right side of the equation which would make it 3r = 45. Then you would divide 45 by 3, equaling 15. So that ends up with r = 15.

How many millimeters are there in 7.89 meters?
O 7,890 millimeters
O 78,900 millimeters
O 789 millimeters
O 789,000 millimeters
Answer:
The first choice: 7,890 millimeters
Step-by-step explanation:
Remember that there are 100cm in a meter; there are 10mm in a centimeter.
100*10=1000
There are 1000 millimeters in a meter.
7.89*1000=7890
There are 7890 millimeters in 7.89 meters.

Answer:
-3(2x-5)<5(2-x)
Step-by-step explanation:
hope this helps
Answer:
x ≥ -3/4
Step-by-step explanation:
3(2x + 5) ≥ 2(x + 6)
Distribute
6x+15 ≥ 2x + 12
Subtract 2x from each side
6x-2x+15 ≥ 2x-2x + 12
4x+15 ≥ 12
Subtract 15 from each side
4x+15-15 ≥ 12-15
4x ≥ -3
Divide each side by 4
4x/4 ≥ -3/4
x ≥ -3/4
Write
in simplest form.

Help plz:))) I’ll mark u brainliest
Answer:
x = 4
Step-by-step explanation:
( 31x + 6 ) + ( 12x + 2 ) = 180
31x + 12x + 6 + 2 = 180
43x + 8 = 180
43x + 8 -8 = 180 -8
43x = 172
43x/43 = 172/43
x = 4
Answer:
x=4
Step-by-step explanation:
31x+6+12x+2=180
43x+8=180
43x=172

Kirby is packing granola bars for a field
trip. He already packed two bags with five granola bars in each bag. He has ten more to pack. How many granola bars will Kirby pack
Answer:20
Step-by-step explanation:
If I'm understanding the questions correctly it is asking how many granola bars in total. So you take the 5 in the 2 bags which is 2•5 which is ten and add those to the ten more he has to pack which is 20.
solve 2x < 10 and plz explain plz .
Answer:
x < 5
Step-by-step explanation:
You can solve an inequality much like you would solve a normal equation.
There are 2x on the left side of the inequality, so divide both sides by two to find what x equals:
2x < 10
(2x)/2 < (10)/2
1x < 5
x < 5
Please give the correct answer and explain im really trying to learn this so I need the explanation not just an answer. Thankyou!
Answer:
x = tan⁻¹(⅘)
Step-by-step explanation:
We can solve for x by using trigonometric ratios (sin, cos, and tan)
We need to apply the appropriate ratio that uses the two sides 8 and 10 from the perspective of x. See attached image for information about ratios. (Source: Math is Fun)
The tangent ratio is opposite divided by adjacent. It will relate x to the two sides. So we would write
tan(x) = ⁸⁄₁₀
Then we simplify and move the tan to the other side by multiplying both sides by the inverse of tan (since you cannot divide by tan)
tan(x) = ⅘
x = tan⁻¹(⅘)
Then we can use a calculator to evaluate x
If you want to find y, now that you have two angles of the triangle, you can find the sum of 90 + x and subtract that from 180 (since all angles of a triangle add up to 180) to find y.

Answer:
(1). [tex]h(t)=-4(t-1)^2+36[/tex]
(2). 1 minute
Step-by-step explanation:
They want you to factorize the equation in such a way that the vertex appears as a number in the equation; and you do that by using a method called completing the squareHere is our equation: [tex]h(t)=-4t^2+8t+32[/tex]We factor it by completing the square: But first remember this:A quadratic equation has the general form [tex]f(x)=ax^2+bx+c[/tex] Where a and b are the numbers before x squared and x respectively, and c is the number without an x, and f(x) is the value dependent on xIn this case x is tSo the steps are as followsEquate the equation to zero: [tex]-4t^2+8t+32=0[/tex] Divide each term by the (a) of the equation in this case is it -4, and we get: [tex]t^2-2t-8=0[/tex] Then take the new (c) to the other side of the equation, in the case we add 8 to both sides to get: [tex]t^2-2t=8[/tex] Now the tricky part, you have to add to both sides of the equation the square of half of the coefficient of t or number before t, not t squared just t and you get: [tex]t^2-2t+(-1)^2=8+(1)^2[/tex] Now the left side is in the square form, or it just means when you factor the left side, you get it as the square of a certain single term, in this case we get: [tex](t-1)^2=8+1[/tex] When we simplify we get: [tex](t-1)^2=9[/tex] Now any equation in this form, will give you the vertex when you equate the term in parenthesis to zero, and simplify: [tex]t-1=0,t=1[/tex] [tex]t=1[/tex] is the value of the t or time at the vertex To write the equation again, multiply every term with the (a) you used to get: [tex]h(t)=-4(t-1)^2+36[/tex] , and this is the equation for #(1)Now here is why we needed to get the vertex; the vertex tells us at what point the height either reaches its maximum/highest level, or where it reaches its minimum/lowest level So since the time (t) at the vertex is 1, in order to find the height at this time, just plug it into the equation:[tex]h(1)=-4((1)-1)^2+36\\h(1)=-4(0)+36\\h(1)=36[/tex] So that's the height at the vertexNow it can either be the maximum/highest height or the minimum/lowest height, in order to know this we check as followsRemember the (a) we used to factor the equation? -4, if the (a) value of a quadratic function is less than 0, then it is a maximum equation, mean whatever vertex you get will be the point where the equation reaches its biggest value.So at a height of 36 meters, and a time of 1 minute, the craft reaches its highest point.Which expression is the factored form of 2/3x+4

What is the slope of y<1/2x-5
Answer:
1/2 is the slope
Step-by-step explanation:
y=mx+b
Answer:
1/2
Step-by-step explanation:
y=mx+b
b= y-intercept
mx=slope
so whatever is mx is the slope for example
y=1/3x+2
1/3 would be the slope because it's mx

Whats the domain???
Answer:
HERE IT IS...
Step-by-step explanation:
the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. It is the set X in the notation f: X → Y, and is alternatively denoted as. Since a function is defined on its entire domain
Answer:
Very simple!
Step-by-step explanation:
The domain of a function is where the function is defined, for the values of x.
Long story short, see the function? Where the blue line passes over the x-vales is the domain. Where there is no blue line over the x-values does not belong to the domain.
Thus, the function is defined for [tex]-8\leq x\leq 8[/tex], or [tex][-8, 8][/tex].
Sorry about the bad explanation.
