Answer:
24 drops of food coloring
Step-by-step explanation:
First, since there are 30 ounces, divide by 5, because there are 4 drops in every 5 ounces of icing. Since 30÷5=6, You have to multiply it by 4 to get 24. You multiply by 4 because there are 4 drops in 5 ounces of icing.
24 drops of food colouring are needed if you are using 30 ounces oficing.

A loan of £5200 gains interest of £2340 in 5 years.
Find the simple interest rate.
= ? % p.a.
Answer:
We have the formula to get the amount of money after 5 years:
A = Principal x (1 + rate)^year
or
5200 + 2340 = 5200 x (1 + rate)^5
=> (1 + rate)^5 = (5200 + 2340)/5200 = 1.45
=> 1 + rate = 1.077

Points X(6, 8), Y(3, 3), and Z(13, –3) form a triangle. What is the area of △XYZ?
Answer:
34
Step-by-step explanation:
area = bh/2
The area of the triangle with vertices X(6,8), Y(3,3), and Z(13,-3) is 34 square units.
Coordinates of vertices are:
X≡(6,8)
Y≡(3,3)
Z≡(13,-3)
What is the area of a triangle with vertices [tex](x_1,y_1), (x_2,y_2),(x_3,y_3)[/tex]?The area of a triangle with the above vertices is given by:[tex]\frac{1}{2} [x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)][/tex]
So the area of the triangle with vertices X(6,8), Y(3,3), and Z(13,-3)
=[tex]\frac{1}{2} [6(3+3)+3(-3-8)+13(8-3)][/tex]
=34 square units.
Hence, the area of the triangle with vertices X(6,8), Y(3,3), and Z(13,-3) is 34 square units.

You must create a triangular Animal pen that covers 40 square yards however it has to contain a 30-degree angle. Give the lengths of two sides of a triangle that include the angle but has an area of 40 sq yards.
Answer:
a=16 b =10 or any other combination that gives 160
a = 20 b=8
a = 32 b = 5
Step-by-step explanation:
The area of a triangle using the lengths of two sides and the sine of the included angle is ½ ab sin C where a and b are sides and C is the angle.
A =40 = 1/2 ab sin 30°
sin 30° = 1/2 so
40 = 1/2*ab*1/2
40 =1/4 ab multiply each side by 4
160 = ab
any combination of sides that gives you 160 will work
Let's check if a=16 b =10
A = 1/2*16*10 sin 30°
A = 1/2*160*1/2
A = 40
Find the lateral area of the right prism with height 0.3 dm, if the base of the prism is Isosceles trapezoid with bases of 3 cm and 5 cm, and legs of 4 cm;
Answer:
48 cm²
Step-by-step explanation:
The lateral area (L) of a trapezoidal prism is the area of the four rectangles that connect the top and bottom trapezoids.
The four rectangles make one large rectangle with length equal to the sum of the four sides — the perimeter (p).
1. Convert the height to centimetres
[tex]h = \text{0.3 dm} \times \dfrac{\text{10 cm}}{\text{1 dm}} = \text{3 cm}[/tex]
2. Calculate the perimeter
p = 3 cm + 4 cm + 5 cm + 4 cm = 16 cm
3. Calculate the lateral area
L = ph = 16 cm × 3 cm = 48 cm²
The lateral area of the prism is 48 cm².

The paper cup is 9 cm tall and the circular opening has a radius of 2.5 cm.
What is the minimum amount of paper needed to make the paper cup to the nearest whole cm² assuming no overlap in the paper?
Answer:
Step-by-step explanation:
Assume that the cup is a cylinder of height 9 cm and radius 2.5 cm.
The side area is A = (circumference)(height), or A = 2πrh, which here is:
A = (3.14)(2)(2.5 cm)(9 cm) = 141.37 cm²
and
The area of the bottom is A = πr², or (here) A = (3.14)(2.5 cm)² = 19.63 cm²
Adding together the area of the sides and the area of the bottom, we get
Total area of cup = 141.37 cm² + 19.63 cm² = 161 cm²

What is the true solution to l n 20 + l n 5 = 2 l n x x = 5 x = 10 x = 50 x = 100
Answer: x = 10
Step-by-step explanation:ln20+ln5=2lnx
ln(20x5)=lnx^2
ln100=1nx^2
100=x^2
square root
x=10
The true solution is x = 10 of the expression ln 20 + ln 5 = 2 ln x which is correct answer would be option (B).
What are the properties of logarithms?There are four basic properties of logarithms:
logₐ(xy) = logₐx + logₐy.
logₐ(x/y) = logₐx - logₐy.
logₐ(xⁿ) = n logₐx.
logₐx = logₓa / logₓb.
According to the problem, we will use some of the basic logarithmic properties,
Given expression,
⇒ ln 20 + ln 5 = 2 ln x
⇒ ln(20×5) = lnx²
⇒ ln100 = lnx²
Take anti logarithms on both sides,
⇒ 100 = x²
Taking the square root,
⇒ x = 10
Hence, the true solution is x = 10.

2x – 7y = - 14
Answer: A! x=-1 2/5, y= 1 3/5
Step-by-step explanation:
First put -3x+3y=9 into slope-intercept form(y=mx+b)
3y=-3x+9
then solve for y
y=-1x+3
enter your y-intercept into the equation below..
2x-7(-1x+3)=-14
2x+7x-21=-14
2x+7x=-14+21(when changing sides it changes signs that's why 21 is now a positive)
2x-7x=7
-5x=7 divide -5 into 7
7/5
x=-1 and 2/5
then input x back into the first equation
-3(7/-5)+3y=9
21/5+3y=9
3y=9-21/5
3y=24/5
divide 3 into 24/5
=24/15=1 and 9/15 reduce it anddd
y=1 and 3/5
