An artist mixes colors for a painting. She mixes 1.5 ounces of blue with 2.5 ounces of yellow to get the perfect shade of green. If she determines that she will need 12 ounces of green, how much yellow paint will she need?
Answer:
4.5 ounces of yellow and 7.5 ounces of blue will create 12 ounces of the perfect shade of green.
Step-by-step explanation:
1.5 + 2.5 = 4 ounces.
Multiply by 3
4.5 + 7.5 = 12 ounces
So, she needs 4.5 ounces of yellow.
A cylindrical container can hold 4 quarts of water if its radius and height are both tripled how much water can it hold?
Answer:
108quartz
Step-by-step explanation:
Volume of a cylinder = πr²h
r is the radius
h is the height
If A cylindrical container can hold 4 quarts of water, then;
4 = πr²h ...... 1
Let the volume be x of the radius and height at tripled
h1 = 3h
r1 = 3r
X = πr1²h1
X = π(3r)²(3h)
X = 9πr²(3h)
X = 27πr²h .... 2
Divide 1 by 2
4/x = πr²h/27πr²h
4/x = 1/27
Cross multiply
x = 4×27
x = 108
Hence the container can hold 108quartz of water of the radius and height was tripled.

The perimeter of a triangle is 69Cm. Side a is 5cm shorter then side b. side c is 5 more than twice side b. Find the length of each side
Step-by-step explanation:
Given parameters:
Perimeter of triangle = 69cm;
Unknown:
Length of each side = ?
Solution:
Side a is 5cm shorter than side b;
b = a + 5 ----- i
Side c is 5 more than twice side b;
c = 2b + 5
The three sides of triangle are a, b and c;
Perimeter is the sum of sides of a body;
a + b + c = 69
From i;
a = b - 5
b
c = 2b + 5
so;
b - 5 + b + 2b + 5 = 69
4b = 69
b = 17.25cm
a = b -5 = 17.25 - 5 = 12.25cm
c = 2(17.25) + 5 = 39.5cm

What is the slope and equation of a line perpendicular to the y-axis passing through point (–5, –3)?
Answer:
Slope: m = 0
Equation: y = -3
Step-by-step explanation:
A line perpendicular to the y-axis always has a slope of 0. Slope is calculated by (y2-y1)/(x2-x1) or rise/run or delta y/delta x (they're all the same thing, delta means difference and is notated with a triangle). When there is no change in y (perpendicular to the y-axis), no matter what the change in x is, the slope will be 0.
Since it is given that one of the points has a y-value of -3, the equation for this line would be y = -3. The formula for a linear equation is y=mx+b. Since the slope is 0, the value of mx is 0, and therefore not needed in the equation. b represents the y-intercept and in this case would be -3.

Which fractions are equivalent to 9 6
Answer:
2/3
Step-by-step explanation:
The fractions which are equivalent to the fraction [tex]\frac{9}{6}[/tex] from the given options are [tex]\frac{3}{2}[/tex] and [tex]\frac{12}{8}[/tex], which are options (A) and (C).
Given a fraction [tex]\frac{9}{6}[/tex].
It is required to find the fraction which is equivalent to the given fraction.
If two fractions are equivalent, then they will be proportional.
The fraction [tex]\frac{9}{6}[/tex] can be written as [tex]\frac{3*3}{2*3}[/tex].
Here, when 3 gets canceled, the resulting fraction is [tex]\frac{3}{2}[/tex].
So, [tex]\frac{3}{2}[/tex] is equivalent to [tex]\frac{9}{6}[/tex].
And, [tex]\frac{3}{2}[/tex] is the simplest fraction that cannot be simplified further.
So, any number multiplied by it both on the numerator and denominator will be an equivalent fraction.
Multiplying both the numerator and denominator of the fraction [tex]\frac{3}{2}[/tex] by 4, the resulting fraction is [tex]\frac{12}{8}[/tex].
Hence, the correct options are (A) and (C).
