(1 / 4) + (1 / 2)
= (1 / 4) + {(1 × 2) / (2 × 2)}
= (1 / 4) + (2 / 4)
= 1 + (2 / 4)
= 3 / 4
(1 / 2) + (3 / 8)
= {(1 × 4) / (2 × 4)} + 3 / 2
= (4 / 8) + (3 / 8)
= (4 + 3) / 8
= 7/8
Answer:
#3 is [tex]\frac{3}{4}[/tex] #4 is [tex]\frac{7}{8}[/tex]
Step-by-step explanation:
you must find a common denominator in both problems.
For #3 the common denominator is 4 so you would multiply [tex]\frac{1}{2}[/tex] by [tex]\frac{2}{2}[/tex] to get [tex]\frac{2}{4}[/tex] then add the numerators together to get 3 and the denominator stays 4.
[tex]\frac{1}{4} + \frac{2}{4} = \frac{3}{4}[/tex]
For #4 the common denominator is 8 so you would multiply [tex]\frac{1}{2}[/tex] by [tex]\frac{4}{4}[/tex] to get [tex]\frac{4}{8}[/tex]
then add the numerators together to get 7 and denominator stays 8.
[tex]\frac{4}{8} + \frac{3}{8} = \frac{7}{8}[/tex]

∆ABC has coordinates A(3, 1), B(5, 5) and C(4, 1). After a translation, the coordinates of A' are (0,0). What are the coordinates of B' and C'?
Answers
Answer:
B'(2,4) & C'(1,0)
Step-by-step explanation:
According To the Question,
Given, We have an ∆ABC that has coordinates A(3, 1), B(5, 5) and C(4, 1).
Now, After a translation, the coordinates of A' are (0,0) .
Then, the coordinate of B' & C' Also changes the same as like A' .
A(3,1) ⇒ A'(0,0) {here from x-axis it reduce 3 and from y-axis it reduce 1}
Same as Above,
B(5,5) ⇒ B'(2,4)
&, C(4,1) ⇒ C'(1,0) .

Answer:
[tex](9\pi - 18)cm^2[/tex]
Step-by-step explanation:
To find the area of this section of the triangle, we will have to find the area of the sector, and then subtract the area of the triangle. To first find the area of the sector of the circle. Remember that the sector of a circle can be found using a proportion of angles. Since there is an angle of 90 degrees in the center. We will take that and divide it by 360 degrees, which is an entire circle. [tex]\frac{90}{360} = \frac{1}{4}[/tex], so the sector is one-quarter of the entire circle. Now find the area of the entire circle which will be [tex]\pi r^{2}[/tex]× [tex]\frac{1}{4}[/tex], where r is 6 since it is the radius of the circle. So therefore the area of the sectore will be a quarter of 36[tex]\pi[/tex], which is 9[tex]\pi[/tex].
Now you must find the area of the triangle with side length 6. Remember, this is an isosceles triangle with sides length of 6 because two of the sides are radii. Also, remember that this is a 90 degree triangle, so the area of the triangle is simply [tex]\frac{6*6}{2}[/tex], which is 18 cm^2.
Now to find the area of just the yellow segment, just take the area of the sector we found, and subtract the area of the triangle. Therefore, the answer is [tex](9\pi - 18)cm^2[/tex]

In a fundraising event for every $3 by basketball players the football players raised $2.50 if the basket ball players use $6 what will the football players raise?
Answers
Answer: $5
Step-by-step explanation:
For every $3 raised by basketball players, football players would raise $2.50.
If basketball players raised $6 therefore, we can use direct proportion to find out what football players raised:
3 : 2.50
6 : x
Cross multiply:
3x = 15
x = 15 / 3
x = 5
Football players raised $5.
At Mike’s Pet shop there are 300 total animals and the ratio of cats to dogs is 7:3. At Pets R Us there are 150 total animals and the ratio of cats to dogs is 6:4. What fraction of the total animals at both stores are cats? Show your work
Answers
Mikes pet shop: add the ratio: 7+ 3 = 10
Divide total animals by the sum:
300/10 = 30
The ratio of cats is 7
Total cats = 30 x 7 =210
Do the same for Pets R Us:
Ratio: 6 + 4 = 10
150/10 = 15
Cats = 15 x 6 = 90
Total cats = 210 + 90 =300
Total animals = 300 + 150 = 450
Fraction that are cats = 300/450 = 2/3
2/3 of the animals are cats

y+94=180
y=180-94

y is 8/5 when x = -4.
Step-by-step explanation:
If the value of "Y" varies directly with "X", we can write y = kx, where k is the constant of proportionality.
If "y=-8,when x=20," then we can find k: -8 = 20k, or k = -2/5.
Then y = (-2/5)x.
If x = -4, then y = (-2/5)(-4) = 8/5
y is 8/5 when x = -4.

in the function f(x) is translated 3 units
Answers
==========================================================
Explanation:
Imagine that we're able to move the xy grid freely but keep the f(x) curve fixed in place. Now imagine that we move the xy grid 3 units to the left. This would give the illusion the f(x) curve moves 3 units to the right.
If we replace each input x with x-3, then that will effectively move the xy grid 3 units to the left. So that's why f(x-3) is a translation of 3 units to the right.
The negative out front will reflect the curve over the x axis. Points of the form (x,y) become (x,-y). For example, if (1,2) is on the curve then (1,-2) is on the reflected curve.
Putting this all together and it leads us to -f(x-3) which is choice D.

If an relationship is proportional what is the missing value from the table?
Answers
Explanation :
In the first row of the table, we find that the -2 is the change, and in the third row -6 is the change.
Using this, we can find that the second row should have -4 subtracted from 16.
We know this because from looking at the changes from the first and second row, the differences multiply by two, as the rows increase. So -2 multiplied by 2 is -4, and 16 subtract 4 is 12.

Answers
Answer:
Surface area of four outer sides = 1,320 inch²
Step-by-step explanation:
Given:
Height of trap = 30 inches
Length of trap = 12 inches
Width of trap = 10 inches
Find:
Surface area of four outer sides
Computation:
Lateral Surface area of cuboid = 2h[l + b]
Surface area of four outer sides = Lateral Surface area of cuboid
Surface area of four outer sides = 2h[l + b]
Surface area of four outer sides = 2(30)[12 + 10]
Surface area of four outer sides = 2(30)[22]
Surface area of four outer sides = 1,320 inch²
