River needs to buy a shade for a window in his house. He measured the width of the window as 27 inches. The actual measurement is 24 inches. What is rivers percent error?
Answer:
12.5%
Step-by-step explanation:
Actual measurement of the window = 24 inches
Measured measurement of the window = 27 inches
We need to find the Rivers percent error. It can be calculated as follows :
% = (|actual value-measured value|)/actual value × 100
[tex]\%=\dfrac{27-24}{24}\times 100\\\\\%=12.5\%[/tex]
So, River's percent error is 12.5%.
Laura has to three cats: The ratio of Socks weight to princess weight is 4:5 The ratio of princesses weight to Luna's weight is 6 :7. What is the ratio of socks weight to Luna's weight?
Answer:
s : l = 24 : 35
Step-by-step explanation:
Let
Socks weight = s
Princess weight = p
Luna's weight = l
The ratio of Socks weight to princess weight is 4:5
s : p = 4 : 5
s / p = 4 / 5
The ratio of princesses weight to Luna's weight is 6 :7
p : l = 6 : 7
p / l = 6 / 7
What is the ratio of socks weight to Luna's weight
Multiply both given ratios
s / p * p / l = 4 / 5 * 6 / 7
p cancel out
s / l = 24 / 35
s : l = 24 : 35
Ratio of socks weight to Luna's weight is 24 : 35

The equation that represents the road is y= ______
Answer:
[tex] y = \frac{1}{6}x - 5 [/tex]
Step-by-step explanation:
The equation that represents the road can be written as [tex] y = mx + b [/tex]
Find, m = slope, and b = y-intercept of the line.
Using two points on the line, (-6, -6) and (6, -4), find the slope:
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-6)}{6 -(-6)} = \frac{2}{12} = \frac{1}{6} [/tex]
Substitute x = -6, y = -6, and m = ⅙ into [tex] y = mx + b [/tex] to find b.
[tex] -6 = \frac{1}{6}(-6) + b [/tex]
[tex] -6 = -1 + b [/tex]
Add 1 to both sides
[tex] -6 + 1 = b [/tex]
[tex] -5 = b [/tex]
Substitute m = ⅙, and b = -5 into [tex] y = mx + b [/tex].
✅The equation that represents the road would be:
[tex] y = \frac{1}{6}x + (-5) [/tex]
[tex] y = \frac{1}{6}x - 5 [/tex]

What are the rules of exponents?Some of the rules of exponents are as follows,
The product of two exponents having the same power is equal to the power of their base multiplied.
The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.
The given expression is 0.2³.
It can be evaluated using the expression a³ = a × a × a.
Thus, the value of the given expression is given as,
0.2³ = 0.2 × 0.2 × 0.2
= 0.04 × 0.2
= 0.008
Hence, the given expression can be evaluated to get the result as 0.008.

The value of angle 'a' will be 40° for the given polygon.
What is a polygon?A polygon is a closed polygonal chain made up of a finite number of straight line segments and is a type of plane figure in geometry. A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both.
Given that the polygon has three sides and the two angles are 56° and 84°. The value of the third angle will be calculated as:-
Angle ∠ a = 180 - 84 - 56
Angle ∠ a = 40°
Hence, the value of the angle 'a' is 40°.

Sahil has a fish tank in the shape of a cuboid, as shown in the diagram
Answer:
12
bcz he can't put a 0.725 fish so it will be rounded up back to 12
The greatest number of neon tetra fish he puts in the tank is 12.
What is cuboid?A cuboid is a solid in three dimensions with six rectangular faces, eight vertices, and twelve edges. Three dimensions, including length, breadth, and height, define a cuboid. A cuboid with integer edges is referred described as being perfect.
Given:
Sahil has a fish tank in the shape of a cuboid, as shown in the diagram.
The tank is 55 cm wide, 28 cm long and height is 33 cm.
And the surface of the water in the tank is 3 cm below the top of the tank.
That means,
to determine the volume,
So, the volume of cuboid
= 55 x 28 x 33
= 50820 cubic centimeters.
And we know 1000 cubic centimeters is 1 liter of water.
So, 50820 = 50.820
And divide by 4
We get the greatest number of neon tetra fish he puts in the tank.
50.820 / 4
= 12.705
≈ 12
Therefore, 12 is the required number for neon tetra fish.

A rectangular swimming pool has a volume of 1750 ft.³ water is being added to the pool at a rate of about 20 ft.³ per minute. use an equation in point slope form to determine about how long will it take to fill the pool completely if there were already 1125 gallons of water in the pool use the fact that one cubic foot of space holds about 7.5 gallons of water round the answer to the nearest integer if necessary
Answer:
You have a rectangular pool 15 X 30 X 5 feet
The floor of the pool is 15X30 = 450 ft2
Two sides are 5X15 = 2(75) = 150 ft2
Two sides are 5X30 = 2(150) = 300 ft2
Total area to be painted: 900 ft2
(900 ft2)/(250 ft2/gal) = 3.6 gallons
Since we can't purchase .6 gallons we
must purchase 4 gallons of paint
The volume of the pool is 15X30X5 = 2250 ft3
1 ft3 = 7.48 gallons
2250(7.48) = 16,830 gallons of water

The slope that passes through the points (–2, 1) and (–4, –7) is 4.
The slope formula can be represented below:
m = y₂ - y₁ / x₂ - x₁Therefore, the slope that passes through the points (–2, 1) and (–4, –7) can be found below
m = - 7 - 1 / -4 - (-2)
m = - 8 / -4 + 2
m = -8 / -2

Jael has a monthly budget of x dollars. She spends $1,500 on her mortgage every month. One-fourth of her remaining budget is spent on recreational activities. Which equation below can be used to determine the amount, in dollars, spent on recreational activities?
A. y=1500+x/4
B. y=(x-1500)/4
C. y=1500-x/4
D.y=(x+1500)/4
And show work so I could understand!
Answer:
B. y=(x-1500)/4
Step-by-step explanation:
Given that:
Monthly budget = x dollars
Monthly mortgage = $1500
Recreational activities = 1/4 of remaining budget
Amount in dollar spent on recreational activities =
(Monthly budget - monthly mortgage) * 1/4
(x - 1500) * 1/4
Hence,
y = (x - 1500) / 4
