Answer:
7/8
Step-by-step explanation:
Find the common denominator:
4 and 8 are both the least common multiple of 8.
So that would be the common denominator.
To get 3/4 to become a fraction of 8, you would multiply both 3 and 4 by 2.
[tex]\frac{1}{8} + \frac{3}{4} = \frac{1}{8} + \frac{6}{8} = \frac{7}{8}[/tex]

3. Two computers in an office are connected to the same printer. The two computers and the printer form an isosceles triangle. Each computer is 30ft away from the printer. Don wants to connect the two computers to each other and needs to calculate how much cable will be necessary. He knows that 30 feet of cable already joins each computer to the printer and each computer is 40 degrees from the printer. Find the amount of cable needed to connect the two computers
Determine the point estimate. An article in an educational journal discussing a non-conventional high school reading program reports a 95% confidence interval of (520 , 560) for the average score on the reading portion of the SAT. The study was based on a random sample of 20 students and it was assumed that SAT scores would be approximately normally distributed. Determine the sample mean that was used to build this confidence interval.
Answer:
Step-by-step explanation:
CI ( 95 % ) means α = 5 % α = 0,05 α /2 = 0,025
If we have a normal distribution and build a CI by symmetry such CI has as a middle point the mean in this case
CI 95 % = ( 520 ; 560 )
the mean is (520 + 560 ) / 2
mean = 540
Which function is represented by this graph?
Answer:
Which function is represented by this graph?
9
The last option is not even a function, because it ambiguously defines the endpoints.
The first option doesn't define the endpoint, because they are always excluded.
So, the correct option is the second one, because it includes the left endpoint and excludes the right one

716x7 multiply with expanded form
Answer:
The expanded form is y=716x7
Step-by-step explanation:
Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression. 5,325 in expanded notation form is 5,000 + 300 + 20 + 5 = 5,325.

Step-by-step explanation:
The age of a mother is three times the age of her son. If the difference between their
ages 20 years find their present ages.
Answer:
[tex]Mother = 30\ years[/tex]
[tex]Son = 10\ years[/tex]
Step-by-step explanation:
Given
[tex]M = Mother[/tex]
[tex]S = Son[/tex]
From the first statement:
[tex]M = 3S[/tex]
From the second:
[tex]M - S = 20[/tex]
Required
Find M and S
We have:
[tex]M = 3S[/tex] and
[tex]M - S = 20[/tex]
Substitute [tex]M = 3S[/tex] in [tex]M - S = 20[/tex]
[tex]3S -S =20[/tex]
[tex]2S = 20[/tex]
Divide both sides by 2
[tex]S = 10[/tex]
Substitute [tex]S = 10[/tex] in [tex]M = 3S[/tex]
[tex]M = 3 * 10[/tex]
[tex]M = 3 0[/tex]
Hence;
[tex]Mother = 30\ years[/tex]
[tex]Son = 10\ years[/tex]

Write the equation of the graphed circle.
a computer repair company charges an hourly labor rate of $40 in addition to.the cost of oarts needed to.fic a computer. A sales tax rate of 5.5% is assessed on the cost of parts but not on the labor cost nancy had gee computer repaired by the company and the total bill came to $183.30!if it took 3. hours to.do the repair what was the cost of parts needed ti fix her comouter rounded to.the nearest whole.dollar write an equation and explain how yiu use it to find your answer
Answer:
Step-by-step explanation:
Parts + 3($40 labor)=183.30
parts + 120=183.30
parts=63.30 but it includes tax. To find costs of parts before tax you
63.30/1.055=60 so parts are $60
or to solve with one equation:
parts(1.055) + 3($40 labor) = 183.30
parts(1.055) + 120=183.30
parts(1.055)=63.30
Parts = 63.30/1.055
parts = 60
4. If the sides of a square measure 9V3 units, then find the length of the diagonal.
Answer:
Step-by-step explanation:
To find the diagonal, use Pythagorean theorem,
diagonal² = side² + side²
= (9√3)² + (9√3)²
= 9²(√3)² + 9²(√3)²
= 81*3 + 81*3
= 243 + 243
= 486
diagonal = √486 = 22.05 units

What is the equation of a line in slope intercept form parallel to 2x-y=2 and passes through point 1,10
Answer:
Slope intercept form:
y = 2x + 8
Step-by-step explanation:
Parallel lines have same slope. SO find the slope of 2x - y = 2
2x - y = 2
-y = -2x + 2
Multiply both sides by (-1)
-y*(-1) = -2x*(-1) + 2 *(-1)
y = 2x - 2
Slope = 2
m =2 and point (1 , 10)
Slope point form: y - y1 = m(x -x1)
y - 10 = 2(x - 1)
y - 10 =2x - 2
y = 2x - 2 + 10
y = 2x + 8

The ratio of cherry trees to apple trees at an orchard is 4 to 9. If there are 184 cherry trees, use a proportion to find a, the number of apple trees.
The formula v= u + at can be used to calculate
Rearrange the formula to make u the subject.
Answer:
u = v - at
Step-by-step explanation:
v = u + at
v - at = u + at - at
v - at = u
u = v - at

Find the area of a trapezoid with a base of 21.6 m, a height of 4.5 m, and top of 11.9 m. Round your answer to the nearest hundredth. 11.9 m 14.5 m 21.6 m
Answer:
[tex]A=75.37\ m^2[/tex]
Step-by-step explanation:
Given that,
The base of a trapezoid, b = 21.6 m
Height of the trapezoid, h = 4.5 m
The tope of the trapezoid, a = 11.9 m
We need to find the area of a trapezoid. The formula for the area of a trapezoid can be given by :
[tex]A=\dfrac{1}{2}\times (sum\ of\ parallel\ sides)\times height[/tex]
Put all the values,
[tex]A=\dfrac{1}{2}\times (21.6+11.9)\times 4.5\\\\=75.37\ m^2[/tex]
Hence, the area of a trapezoid is equal to [tex]75.37\ m^2[/tex].
