A full tub of water weighs 3 1/8 pounds. If the tub is filled up only 1/7 full how much would it weigh?
Answer:
[tex]\frac{25}{56}[/tex] pounds
Step-by-step explanation:
By using unitary method,
∵ 1 full tub of water weighs = [tex]3\frac{1}{8}[/tex] pounds
∴ [tex]\frac{1}{7}[/tex] of a water tub will weigh = [tex]3\frac{1}{8}\times \frac{1}{7}[/tex]
= [tex]\frac{(24+1)}{8}\times \frac{1}{7}[/tex]
= [tex]\frac{25}{56}[/tex] pounds
Therefore, water filled in [tex]\frac{1}{7}[/tex]th part of the tub will weigh [tex]\frac{25}{56}[/tex] pounds.
The weight of the tub if filled up to 1/7 full is 25/56 pounds
How to find product of fractionGiven:
Full weight of tub = 31/8 poundsIf filled halfway:
= 1/7 × 3 1/8
= 1/7 × 25/8
= (1 × 25) / (7 × 8)
= 25/56 pounds
Therefore, the weight of the tub if filled to 1/7 of the capacity is 25/56 pounds

how do you solve this two step equation? 5 -2/3x =3
Answer:
x = 3
Step-by-step explanation:
I will assume you meant 5 - (2/3)x = 3. This simplifies to -(2/3)x = -2, or
(1/3)x = 1, so that x = 3.

"2/3x" could be interpreted as --------- which would give us a very different
3x result. Use parentheses to

Kosey needs to get 80% of his
questions correct on his math test
to get a B for the quarter. If his
test has 60 questions, how many
questions will he need to get right?
Answer:
48 questions
Step-by-step explanation:
There are 60 questions on the test
to see how many questions he needs to solve to get 80% we multiply 60 with 80 and divide it by 100
60 x 80 ÷ 100 = 48
Solve the system.
2x + y = 3
-2g = 14 – 6x
Write each equation in slope-intercept form.
Answer:
x = 2, y = -1
Step-by-step explanation:
Assuming it should be y not g
y = -2x + 3
-2y = -6x + 14
y = 3x - 7
-2x + 3 = 3x - 7
10 = 5x
x = 2
y = -1

The price of a watch was increased by 20% to £198.
What was the price before the increase?
Answer:
$165 Hope this helps! May I have brainliest? I need to level up?
Step-by-step explanation:
To find the original price before the increase, divide the new price by 1 + the percent of increase.
198 / 1.20 = 165

C. 68 + 2x = 180
D. 34 + 2x = 180
please help me this is geometry and i am so clueless!!!!!
Answer/Step-by-step explanation:
Problem 1:
E is the centroid of the triangle.
Centroid theorem states that the centroid is ⅔ of the distance of each vertex to the midpoint of the side opposite each vertex.
This implies that:
AE = ⅔(AD)
AE = 21
Therefore:
21 = ⅔(AD)
3*21 = 2(AD)
(3*21)/2 = AD
31.5 = AD
AD = 31.5
Problem 2: Apply the centroid theorem. Thus:
DE = ⅓(AD)
DE = 12
Therefore,
12 = ⅓(AD)
12*3 = AD
36 = AD
AD = 36

If ARST is an equilateral triangle, find x and y.
Answer:
x = 120
y = 30
Step-by-step explanation:
Given that RST is equilateral, each of its interior angles will be 60 degrees
Looking at x, it lies on a starting line with one of the interior angles of RST
The sum of angles on a straight line is 180
Thus;
x + 60 = 180
x = 180-60
x= 120
Looking at triangle RSU, the markings indicates that we have an isosceles triangle
For an isosceles triangle, the base angles are equal in value
This means that SRU is also y
Mathematically, the sum of angles in a triangle is 180
Hence;
x + y + y = 180
x + 2y = 180
120 + 2y= 180
2y = 180-120
2y = 60
y = 60/2
y = 30
A population of 130,000 grows 4% per year for 16 years.
How much will the population be after 16 years?
Let's consider the scenario after each year:
After the zeroth year, the population is: 120 000(1 + 0.04)⁰
After the first year, the population is: 120 000(1 + 0.04)¹
After the second year, the population is: 120 000(1 + 0.04)²
...
Thus, we can find the general rule:
After the nth year, the population is: 120 000(1 + 0.04)ⁿ
And after the 16th year, the population is 120 000(1 + 0.04)¹⁶ = 224 758 (rounded to nearest whole number)
If Circle A has a radius that is five more than twice as long as the radius of circle B and the sum of the diameters of the circle is 88 inches, find the area and circumference of circle A
Answer:
Circumference of a circle A = [tex]389.7 \,\,inches[/tex]
Area of a circle A = 12081.1 square inches
Step-by-step explanation:
Let [tex]r[/tex] denotes radius of circle B.
Circle A has a radius that is five more than twice as long as the radius of circle B.
So,
Radius of circle A = [tex]5+2r[/tex]
Diameter of circle = 2 (radius of circle)
So,
Diameter of circle B = 2r
Diameter of circle A = [tex]2(5+2r)[/tex]
Sum of the diameters of the circles A and B = [tex]2r+2(5+2r)[/tex]
[tex]=2r+10+4r[/tex]
[tex]=6r+10[/tex]
As sum of the diameters of the circles is 88 inches,
[tex]6r+10=88\\6r=78[/tex]
[tex]r=13[/tex] inches
Radius of a circle A = [tex]2(5+2r)[/tex]
[tex]=2[5+2(13)][/tex]
[tex]=2(5+26)[/tex]
[tex]=2(31)[/tex]
[tex]=62[/tex] inches
Let R denotes radius of a circle A.
R = 62 inches
Circumference of a circle [tex]=2\pi R=2\pi (62)=124\pi =124(\frac{22}{7})=389.7 \,\,inches[/tex]
Area of a circle [tex]=\pi r^2=\pi (62)^2=3844\pi=3844(\frac{22}{7})=12081.1[/tex] square inches
Can someone help me please
