Determine whether the given value is a solution of the equation.
b
6; b =78
13
78 (select) a solution.
is 78 the solution or not
Answer:
78 is a solution
Step-by-step explanation:
The given equation is b/13 = 6
Therefore, by applying the multiplication property of equality, we have by multiplying both sides by 13, we have;
b/13 × 13 = 6 × 13
The 13 in the denominator of b/13 divides the 13 in the multiplicand to give 1, and we get the following equation
b/13 × 13 = b × 1
Therefore;
b/13 × 13 = b × 1 = 6 × 13 = 78
b × 1 = 78
By the multiplicative identity property of '1', we get;
b × 1 = 1 × b = b
∴ b × 1 = b = 78
b = 78
∴ 78 is a solution of the equation.

Answer:
2z(4z^2+1)(2z+1)(2z-1)
Step-by-step explanation:
here is just some basic polynomial factoring where you find something both the numbers have in common and you take that out of the equation. here i just went a little bit deeper and after taking out the common factor i also expanded my answer further as this would be the fully correct answer.

The longest side of triangle is 10 cm which group of line segments could form the other 2 sides of the triangle
Answer
A 5cm and 5 cm
B 7cm and 8cm
C 4cm and 4cm
D 9cm and 10 cm
Please i need to know
Answer:
The group of line segments that could form the other 2 sides of the triangle is;
B. 7 cm and 8 cm
Step-by-step explanation:
The triangle inequality theorem states that the sum of the length of any two sides of a triangle is larger than the length of the third side
The given parameter of the triangle is that the length of the longest side of the triangle = 10 cm
Let, 'a', and 'b', represent the remaining two sides of the triangle
Therefore, by the triangle inequality theorem, we have;
(1) a + b > 10 cm
(2) 10 cm + a > b
(3) 10 cm + b > a
The option that satisfies condition (1), (2), and (3) are options 'B' and 'D', for which we have;
7 cm + 8 cm = 15 cm > 10 cm
10 cm + 7 cm = 17 cm > 8 cm
10 cm + 8 cm = 18 cm > 7 cm
9 cm + 10 cm = 19 cm > 10 cm
10 cm + 9 cm = 19 cm > 10 cm
10 cm + 10 cm = 20 cm > 9 cm
Therefore, the possible combination of the other two sides are;
7 cm and 8 cm or 9 cm and 10 cm
However, a side of option 'D' is 10 cm and given that the longest side of the triangle = 10 cm, the length of each of the other two side should be less than 10 cm and the only given possible combination of the other two side should be option 'B', 7 cm and 8 cm.
Answer:
B 7cm and 8cm

Answer:
[tex]y = 7.3[/tex]
Step-by-step explanation:
Solve the quadratic equation.
m^2/15 -3 = 2
The answer is [tex] 5 \sqrt{3} [/tex]
Explanation :[tex] \frac{ {m}^{2} }{15} - 3 = 2[/tex]
[tex] \frac{ {m}^{2} }{15} = 2 + 3[/tex]
[tex] \frac{ {m}^{2} }{15} = 5[/tex]
[tex] {m}^{2} = 5 \times 15[/tex]
[tex] {m}^{2} = 75[/tex]
[tex]m = \sqrt{75} [/tex]
[tex]m = \sqrt{25 \times 3} [/tex]
[tex]m = \sqrt{25} \times \sqrt{3} [/tex]
[tex]m = 5 \sqrt{3} [/tex]

Calculate the measures of spread for Mrs Hampton's class data. Justify your
response by describing the process used to find each measure, (2 points)
The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.
Interquartile Range:
Given the Data -> First Quartile = 2, Third Quartile = 5
Interquartile Range = 5 - 2 = 3
Range: 8 - 1 = 7
Variance:
We start by determining the mean,
[tex]\:1+\:2+\:3+\:3+\:3+\:5+\:8 / 7 = 3.57[/tex]
n = number of numbers in the set
Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.
[tex]\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n-1},\\\\=> SS/n - 1\\\\=> 31.714/7 - 1\\=> 5.28571[/tex]
5.3
Standard Deviation
We take the square root of the variance,
[tex]\sqrt{5.28571} = 2.29906[/tex]
2.3
If you are not familiar with variance and standard deviation, just leave it.

Step-by-step explanation:
since a triangle's total angle is 180 degrees,
(5x + 18) + (3x + 2) + (x + 16) = 180
9x + 36 = 180
9x = 144
x = 16
m<D = (3x + 2)
m<D = 3(16) + 2
m<D = 48 + 2
m<D = 50 (your answer)

Find the values of x and y.
Answer:
y=180-63-63/2=27degree...in triangle mln
x=180-27-63=90....in triangle mon
Answer:
y=27, x=80
Step-by-step explanation:
∠N= 63°(angles opposite to equal sides)
2∠y+63+63=180°(angle sum property)
2∠y=54°
∠y=27°
27°+63°+∠x=180°(ASP)
∠x=180°-90°=90°

a. 5t+4t =9t
b. t+5+4= t+9
c. 9t
d. 4×5×t= 20t
e. t(5+4)- do the inside the parenthesis first. =9t
the answer would me B and A because the answer isn't 9t so it would be those!! also the boxes on the right you multiply t×5 and t×4 and that would be 5t + 4t =9t

find the volume of metal required to make a closed box of thickness 1 cm with external measurements 12 cm × 7 cm × 10
Answer:
The volume of the metal is:
[tex]V_{t}=548\: cm^{3}[/tex]
Step-by-step explanation:
First, let's find the volume of the front face of the square:
[tex]V_{1}=12*7*1=84\: cm^{3}[/tex]
The back face is the same, so we have:
[tex]V_{2}=84\: cm^{3}[/tex]
The volume of the side faces will be:
[tex]V_{3}=7*10*1=70\: cm^{3}[/tex]
[tex]V_{4}=70\: cm^{3}[/tex]
And finally, the volume of the top and bottom side faces of the box will be:
[tex]V_{5}=12*10*1=120\: cm^{3}[/tex]
[tex]V_{6}=120\: cm^{3}[/tex]
The total volume of the metal will be:
[tex]V_{t}=V_{1}+V_{2}+V_{3}+V_{4}+V_{5}+V_{6}[/tex]
[tex]V_{t}=2(84)+2(70)+2(120)[/tex]
[tex]V_{t}=548\: cm^{3}[/tex]

If, on their own, it takes 6 hours for Person A to complete a task and 9 hours for Person B to complete the same task, then how many hours would it take if they worked together? Estimate your answer to 4 places after the decimal, if necessary.
Answer:
Step-by-step explanation:
A does 1/6 of the task per hour.
B does 1/9 of the task per hour.
Together, they do 1/6+1/9 = 5/18 of the task per hour, finishing in 18/5 hours.
18/5 = 3.6 hours
