Answer:
80+80=160
80+80+80=240
240 >160
so no it is not equal
thank you for your time!
Step-by-step explanation:
In Mathematics, the order of operations (BOMDAS or BIDMAS) dictates that multiplication operations should be performed before addition. Hence, in the mathematical expression '80 + 80 equals 80 + 80 * 80 equals', the multiplication operation (80*80) is performed first, resulting in '80 + 6400 = 6480'. Therefore, 80 + 80 equals 6480.
Explanation:In Mathematics, the operation order matters, this order is known by the acronym BOMDAS or BIDMAS, which stands for Brackets, Orders, Multiplication and Division, and Addition and Subtraction. it is used to clarify which procedures should be performed first in a given mathematical expression.
In your question, '80 + 80 equals 80 + 80 * 80 equals', we have both addition and multiplication operations. According to BIDMAS rules, we perform multiplication first before addition. Hence, the given expression is equivalent to 80 + 80 equals 80 + (80 * 80), where (80*80) should be calculated first.
Putting this into practice, we get: 80 + (80 * 80) = 80 + 6400 = 6480. Therefore, 80 + 80 equals 6480, based on the principles of BIDMAS or BOMDAS.

in the diagram below, <AFB = <EFD. if m<EFD = (5x+6)°, m<DFC = (19x-15)°, and m<EFC = (17x+19)°, find m<AFE
Answer:
m<AFE = 128°.
Step-by-step explanation:
Step 1: Find the value of x
Angle EFD + Angle DFC = Angle EFC
5x + 6 + 19x - 15 = 17x + 19
24x - 9 = 17x + 19
7x = 28
x = 4
Step 2: Find all angles
Angle AFB=Angle EFD= 5x + 6
5(4) + 6 = 26°
Angle DFC = 19x - 15
19(4) - 15 = 61°
Step 3: Find angle AFE
Line BD is a straight line and all angles on a straight line are equal to 180°.
Angle AFB + Angle AFE + Angle EFD = 180°
26 + BFC + 26 = 180°
BFC = 180 - 52
BFC = 128°
Therefore, m<AFE is equal to 128°.
!!
The measure of m<AFE if m<EFD = (5x+6)°, m<DFC = (19x-15)°, and m<EFC = (17x+19)° is 128degrees
Angle is the point where two or more lines meet. From the given diagram:
m<EFC = m<EFD + m<DFC
Given the following:
m<EFC = 17x + 19
m<EFD = 5x+6
m<DFC = 19x - 15
Substitute the given values into the expression
17x + 19 = 5x + 6 + 19x - 15
17x - 5x - 19x = -19 - 9
12x - 19x = -28
-7x = - 28
x = 28/7
x= 4
Get the angle m<AFE
m<AFE + m<ABF + m<EFD = 180
Since <AFB = <EFD
m<AFE + m<EFD + m<EFD = 180
m<AFE + 2m<EFD = 180
m<AFE + 2(5x+6) = 180
m<AFE + 2(5(4) + 6) = 180
m<AFE +2(26) = 180
m<AFE + 52 = 180
m<AFE = 180 - 52
m<AFE = 128 degrees
Hence the measure of m<AFE is 128degrees

Step-by-step explanation:
Oof, all 6? That's not fun.
I'm going to show you one for the first bunch, (4-12) and hopefully you can get the rest. If not let me know and I can more carefully work you through some others on here.
4) So first we need the angle. How do we find that? Well, we know it's somewhere between 270 and 360 degrees (or 3pi/2 and 2pi radians) since it's in the fourth quadrant. The method to finding the angle is ifferent for each quadrant, but it's nice to know around where you'll get. Anyway,, if we take 360 and subtract that little space that is unlabeled we will know the rest. Hopefully that makes sense, but let me know if not, it's important to understand. Maybe think of what happens if you add the two together, you get around the whole circle then.
Anyway, to find that little sliver, we are going to construct a right triangle wherethe x axis is one side. If you draw a line connecting point p and the x axis you have this right triangle. I am going to call this sliver we don't know s. ANyway, now we use trig here.
s = arcsin(3/5) (you can find 5 pretty easily but let me know if you don't see it.)
You may think to use -3 instead of 3, and it wouldn't be a huge mistake, it will just give you the negative version of what we want.
Anyway, now we know theta is 360-s (or 2pi-s). You can solve s or leave it as arcsin(3/5) so you don't have to round.
Now we can solve the trig functions. If you don't know the sum and difference trig identities you will have to round. They are pretty simple formula though. For instance, sin(2pi - arcsin(3/5)) = sin(2pi)cos(arcsin(3/5))-cos(2pi)sin(arcsin(3/5)) = 0 - 3/5 = -3/5 You will also want to know that s = arcsin(3/5) = arccos(4/5) = arctan(3/4). ROunding will get you close but not exact.
Again, let me know ifyou need any more help, they should just be a lot of doing the same thing over and over and over again though.
14) For 14 and 16 you just need to know how the graphs of sin, cos and tan look. Is this something you have trouble with? Like could you draw the graphs at the intervals of increasing/ decrasing and all. if not I can give a quick explanation.
What type of number is -5.41? 1. Whole number 2. integer 3. Rational 4. Irrational
The number -5.41 can be classified as a Rational number because it can be expressed as a fraction where both the numerator (-541) and the denominator (100) are integers and it's not a whole number or an integer because it's negative and has a decimal part.
Explanation:The number -5.41 is a type of number classified as a Rational number. Rational numbers are numbers that can be written as a fraction, where both the numerator and the denominator are integers (whole numbers), and the denominator is not zero. They can also be positive, negative, or zero, and they can be represented as decimals that terminate (like 0.2 or -1.75) or repeat (like 0.333... or -0.666...).
The number -5.41 is not a positive whole number nor an integer because it is negative and has a decimal part, which disqualifies it from both categories. An irrational number, on the other hand, is a number that cannot be expressed as a simple fraction, which clearly does not apply to -5.41 as it can be easily expressed by the fraction -541/100.

A pond is being drained through an outlet pipe, then will be filled through an inlet pipe. If the inlet pipe can fill the pond in 9 hours and the outlet pipe can empty the pond in 15 hours, how long would it take to fill the pond if the outlet pipe was left open?
Answer:
22.5 hours
Step-by-step explanation:
I am using "1 pond" to mean the volume of water that fits in the pond.
The inlet pipe fills the pond in 9 hours.
The filling rate is (1 pond)/(9 hours) = 1/9 pond/hour
The outlet pipe empties the pond in 15 hours.
The emptying rate is (1 pond)/(15 hours) = 1/15 pond per hour
The difference in rates is the net rate at which the pond is filling up.
1/9 pond/hour - 1/15 pond/hour =
= 5/45 pond/hour - 3/45 pond /hour
= 2/45 pond/hour
The pond is filling at a rate of 2/45 pond/hour.
To find the time it takes to fill the pond, we divide 1 pond by the rate.
(1 pond)/(2/45 pond/hour) = 45/2 hour = 22.5 hours

Hello!
So, let's go over some information we know. We know that all the interior angles of a triangle add up to 180 degrees. We know that a line measures 180 degrees. We, therefore, know that angles which make up a line are supplementary, and must add up to 180 degrees.
So, first, we can find angle ABC. We can find this because angle ABC and ABT add up to 180 degrees, and we know the measure of ABT to be 125 degrees. Therefore:
ABC + 125 = 180
ABC = 55 degrees
Now, we can find angle ACB. We can find this as we have angle ABC and CAB, and angle ACB + ABC + CAB = 180 degrees (as they are the three interior angles of triangle ABC). ABC measures 55 degrees, and CAB 60 degrees. Therefore:
55 + 60 + ACB = 180
115 + ACB = 180
ACB = 65 degrees
Finally, we can find angle ACR based off of ACB, as ACB and ACR make up one line, and, therefore, add up to 180 degrees. ACB measures 65 degrees.
ACR + 65 = 180
ACR = 115 degrees
Therefore, your answer is choice 2, or 115 degrees.
Hope this helps!
Answer:
115°
Step-by-step explanation:
m∠ABC = 180° - 125° = 55° (angles in a straight line add up to 180°)
Given that m∠CAB = 60°,
Then m∠ACR = m∠CAB + m∠ABC (exterior angle is equal to the sum of opposite interior angles).
m∠ACR = 60° + 55° = 115°

4∣x−9∣+9 = −3∣x−9∣+9
cancel equal terms on both sides of the equation
4∣x−9∣+9 = −3∣x−9∣+9the statement is true but only if both sides equal 0
4∣x − 9∣= −3∣x − 9∣4 x | x - 9| = 0−3∣x − 9∣= 0solve the equation for x
4x |x -9| = 0divide both sides of the equation by 4
