Answer:
$75.60
Step-by-step explanation:
Given:
Remi buys a fish tank for $70. The sales tax is 8%To Find:
What is the total cost of the fish tank, including sales tax?
Note:
Sales Tax ⇒ Increase ⇒ Add
8% = 0.08
Solve:
$70 × 0.08 = 5.60
$70 + 5.60 = 75.60
Hence, total cost of the fish tank including sales tax is $75.60

Find the area of the figure below.
I am stuck on this too...
Maybe we can figure it out together
F(x)=(x-6)2(x+2)2
Determine number of roots
Answer:
(x - 6)^2 = 0 or (x + 2)^2 = 0
Take the square root of both sides:
x - 6 = 0 or (x + 2)^2 = 0
Add 6 to both sides:
x = 6 or (x + 2)^2 = 0
Take the square root of both sides:
x = 6 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 6 or x = -2
Step-by-step explanation: the answer is x= 6 or = -2

B) x - 5y = 20
C) 20x - 2y = 1
D) 5y = 2
Answer:
B) x-5y=20
Step-by-step explanation:
y-y1=m(x-x1)
y-(-5)=1/5(x-(-5))
y+5=1/5(x+5)
y=1/5x+5/5-5
y=1/5x+1-5

Answer: 33 degrees
Step-by-step explanation:
Since J and K are midpoints, JK must be parallel to GH.
If the linese are parallel, then angle IHG would equal angle IKJ because they would be corresponding angles. We can now set up an equation.
-7x + 75 = -4x + 57
Combine like terms:
3x = 18
Divide both sides by 3:
x = 6
Therefore, -7x + 75 = -7*6 + 75 = -42 + 75 = 33

Find the value of y in the diagram.
ΔLMN ~ ΔABC
Answer:
y = 6.3
Step-by-step explanation:
ΔLMN ~ ΔABC
The two triangles are similar which means the sides have the same proportions. To put it simply, one shape is just an enlargement of the other.
In this case, triangle ABC is an enlargement of triangle LMN so we can work out a scale factor.
To work out the scale factor, we can do 10 ÷ 7 = 1.4285714... To find y, all we have to do is divide 9 by the scale factor to get 6.3.
Hope this helps!
Ratio remains same as triangles are similar

The figure shows 3 semicircles and a right-angled triangle, Find the total area of the shaded parts. (Take a = 3.14)
Answer:
A semicircle is drawn with AC as diameter. If AB = BC = 7 cm, find the area of the shaded region. Take π = 22/7. 25. A circular field has perimeter 660 m.
Using the formula for area of circle and right angled triangle, we find that area of shaded region is 96[tex]cm^2[/tex].
Area of circle = [tex]\pi r^2[/tex]
where, r is the radius of circle.
Area of right angled triangle = [tex]\frac{1}{2} * base *height[/tex]
The area of shaded region is given by =
= area of semicircle with AB as diameter + area of semicircle with BC as diameter + area of triangle ABC - area of semicircle with AC as diameter
Now,
area of semicircle with AB as diameter =
AB = diameter = 12cm
radius = 6 cm
area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 6^2 = 56.52[/tex]
area of semicircle with BC as diameter =
BC = diameter = 16cm
radius = 8 cm
area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 8^2 = 100.48[/tex]
area of semicircle with AC as diameter =
AC = diameter = 20cm
radius = 10 cm
area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 10^2 =157[/tex]
area of triangle ABC =
AB = base = 12cm
BC = perpendicular = 16 cm
area(ABC) = [tex]\frac{1}{2}*12*16 = 96[/tex]
The area of shaded region is given by = 56.52 + 100.48 + 96 - 157 = 96[tex]cm^2[/tex]

Would using the commutative property of addition be a good strategy
for simplifying 35 +82 +65? Explain why or why not.
Answer:
Yes
Step-by-step explanation:
Without using the property, you would have to do 35+82+65 which is messy. 35+82=117+65=182 ugh
Using the property however, tells you that you can do 35+65+82 which is easier to solve! 35+65=100+82=182

The height of the mast on the bridge is 148 feet. Using the conversion 1 foot=30cm calculate the height of the mast in metres
Any help would be very useful, thank you
Answer:
44.4 meters
Step-by-step explanation:
Using 1 foot = 30 cm
convert 148 feet to centimeters by multiplying.
148ft × 30cm/1ft
= 148 × 30
= 4440 cm
Then convert cm to meters by dividing by 100.
1 meter = 100cm
4440cm × 1m/100cm
= 4440/100
= 44.4m
148 feet is 44.4m

Janae and Jerome each have m marbles. Gwen has 4(m 2) marbles. John has 8m 4 marbles. If John has more marbles than Janae, Jerome, and Gwen combined, how many marbles might Janae and Jerome each have? Select each possible answer.
Janae and Jerome each have either 3, or 4 or 5 marbles. Option C, D and E are correct.
How do you calculate the value of integer m?Given that the number of marbles has:
Janae = m
Jerome = m
Gwen = 4(m+2)
John = 8m+4
John has more marbles than Janae, Jerome, and Gwen combined, So this can be written as,
[tex]8m+4 \geq m + m + 4(m+2)[/tex]
[tex]8m+4\geq 2m + 4m+8[/tex]
[tex]8m+4 \geq 6m+8[/tex]
[tex]2m\geq 4[/tex]
[tex]m\geq 2[/tex]
It means that the value of m is greater than 2, it can be 3, 4 or 5.
Hence we can conclude that Janae and Jerome each have either 3, or 4 or 5 marbles. Options C, D and E are correct.

When dividing a monomial by another monomial, we divide the coefficients and apply the quotient law of exponents, x m ÷ x n = x m – n to the variables. If both the monomials have negative coefficients, the negative signs cancel out and the answer so obtained will be having a positive coefficient only.
For example, the binomial 2x +4 can be multiplied by the monomial 4x so that (2x) (4x) equals 8x2 and 4·4x equals 16x, using the distributive property. Therefore, (2x +4) (4x) equals 8x2 + 16x.Mar 15, 2016
Use the Quotient Property. When we divide monomials with more than one variable, we write one fraction for each variable. Use fraction multiplication. Simplify and use the Quotient Property.
