326 divided by 53 sender
Answer: 6.150943396
6.15 if rounded
Step-by-step explanation:
26 divided by 53 equals 6 with a remainder of 8.
To solve 326 divided by 53 using long division, let's go step by step:
6
------------
53 | 326
1. First, we divide 53 into 32. The largest multiple of 53 that fits into 32 is 0. So, we bring down the next digit from 326, which is 6.
6
------------
53 | 326
-
2. We now have 326. We divide 53 into 326, which gives us 6. The quotient is written above the line.
6
------------
53 | 326
- 318
3. We subtract 318 from 326, which gives us 8.
6
------------
53 | 326
- 318
-----
8
4. We have a remainder of 8. Since there are no more digits to bring down, we have our final result.
Therefore, 326 divided by 53 equals 6 with a remainder of 8.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Slope = Rise² + Run²
Slope² = 10² + 15²
The slope is 5√13.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
The slope, rise, and run are in the form of a right triangle.
We will apply the Pythagorean theorem to get the slope.
Sope can be considered as the hypotenuse.
Now,
Slope = Rise² + Run²
Slope² = 10² + 15²
Slope² = 100 + 225
Slope² = 325
Slope = √325
Slope = √(25 x 13)
Slope = 5√13
Thus,
The slope is 5√13.

Jordan solved the equation −7x + 25 = 48; his work is shown below. Identify the error and where it was made. −7x + 25 = 48 Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23 Step 3: negative seven times x over seven = twenty-three over seven Step 4: x = twenty-three over seven Step 1: He should have added 25 to each side. Step 1: He should have divided both sides by −7. Step 3: He should have divided both sides by −7. Step 3: He should have multiplied both sides by −7.
Answer:

The average cost in dollars of producing x units of golf clubs is C(x)=x^2-18x+140. Determine the number of golf clubs to produce each hour to keep the cost below $75 per club
Answer:
At least 6
Step-by-step explanation:
I did guess and check for the formula. I first started with 5 golf balls
C(x)=5^2-18*5+141
C(x)=76 too high
Then I tried 6
C(x)=6^2-18*6+141
C(x) = 69
It would have to be 6 because you need a whole number of golf balls and 5 made the cost too high

Answer:
[tex]-\frac{4}{9}z[/tex]-5
Step-by-step explanation:
You can only combine variables with like terms. Variables with like terms are [tex]\frac{7}{9} ( -\frac{6}{9} ) (-\frac{5}{9})[/tex] so 7/9 - 6/9 is 1/9 and 1/9 - 5/9 is -4/9. The other variables with like terms are 2 and (-7). 2 - 7 = -5. Now combining these two together we get the fraction -4/9 -5

Given: MO bisects ∠PMN and OM bisects ∠PON Prove: ΔPMO ≅ ΔNMO Statements Reasons 1. MO bisects ∠PMN 2. ∠PMO ≅ ∠NMO 3. MO ≅ MO 1. Given 2. Definition of angle bisector 3. Reflexive property 4. OM bisects ∠PON 5. ∠POM ≅ ∠NOM 6. ΔPMO ≅ ΔNMO 4. Given 5. Definition of angle bisector 6. ?
From the given statements and reasons, we can deduce that ΔPMO ≅ ΔNMO because; it fulfils the ASA Congruence postulate.
We are given;
1) MO bisects ∠PMN
2) ∠PMO ≅ ∠NMO which means that ∠PMO is congruent to ∠NMO
3) MO ≅ MO
4) OM bisects ∠PON
5) ∠POM ≅ ∠NOM which means that ∠POM is congruent to ∠NOM
6) ΔPMO ≅ ΔNMO
Now, from all the statements given, we can see that two corresponding angles of both ΔPMO and ΔNMO are equal.
We also see that they share a common side which is MO.
Thus, we can say that both triangles have two corresponding sides that are equal and a corresponding included angle that is also equal.
In conclusion, ΔPMO ≅ ΔNMO because it fulfils the ASA Congruence postulate.

Step-by-step explanation:
I drew a diagram on paper but cant here soooo....
but math checks out i think.
Angles AOD and COB are both 36.
Angles AOC and DOB are both 144.
DOB has to be 4 times angle COB, right? if so, then:
144 = 4*36. That checks out. Now to see if all the angles combined are 360.
36 + 36 + 144 + 144 =360. It works!
