Answer:
1 : 3
Step-by-step explanation:
¼ of the biscuits are chocolate while the rest are plain.
Since a fraction is a part of a whole, 1, then it means that the fraction that are plain is:
1 - ¼ = ¾
Therefore, the ratio of chocolate biscuits to plain biscuits is:
¼ : ¾
To put this in simplest dorm, multiply both sides by 4, we have:
1 : 3
This is the ratio of chocolate biscuits to plain biscuits.

When three squares are joined at their vertices to form a right triangle, the combined area of two smaller squares is the same as the area of the largest square find the side of the third square
Answers
Answer:
b = 12 cm
Step-by-step explanation:
The Pythagora's Theorem
The area of a square of side length x is
[tex]A = x^2[/tex]
We have three squares, two of which have side lengths of a=5 cm and b= 13 cm.
The combined area of the smaller squares is the same as the area of the largest square. We cannot say at first sight which square is the largest, we'll assume the square of side length of 13 cm is the largest one. Thus:
[tex]5^2+b^2=13^2[/tex]
Where b is the unknown side length.
The above expression corresponds to the Pythagora's Theorem formula. Solving for b:
[tex]b^2={13^2-5^2=169-25=144[/tex]
[tex]b=\sqrt{144}[/tex]
b = 12 cm
If the circumference of a circle is x, then what is the area of the circle in terms of x?
Answers
Answer:
x^2 / 4pi
Step-by-step explanation:
The area of a circle is (pi x r)^2
The circumference of a circle is 2pi x r
The find the radius, you need to divide x by 2pi, so x / 2pi
Then just plug it in as the radius:
(pi x (x / 2pi))^2 = x^2 / 4pi

Pascha is factoring the polynomial, which has four terms.

(3x2 – 5) (x + 8)
(3x2 – 8) (x + 5)
(3x2 + 8) (x – 5)
(3x2 + 5) (x – 8)
Answers
Answer:
[tex](3x^2 + 8)(x - 5)[/tex]
Step-by-step explanation:
Given
[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
Required
Complete the factorization
[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
When an equation is factorized as:
[tex]a(b + c) + d(b + c)[/tex]
The complete expression is:
[tex](a + d)(b + c)[/tex]
Apply this logic in [tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
By comparison:
[tex]a = 3x^2; b = x; c = -5; d = 8[/tex]
So, we have:
[tex]3x^3 - 15x^2 + 8x - 40 = (3x^2 + 8)(x - 5)[/tex]
Hence,
[tex](3x^2 + 8)(x - 5)[/tex] is the complete factor

What is the decimal equivalent of - 2/5

what is the slope-intercept equation of the line that goes through the points 1, 5 and 2, 8
Answers
Answer:
The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]
Step-by-step explanation:
We need to find the slope-intercept equation of the line that goes through the points (1, 5) and (2, 8)
The general equation for slope intercept form is [tex]y=mx+b[/tex] where m is slope and b is y-intercept
Finding slope
Slope can be found using formula [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x _1=1, y_1=5, x_2=2, y_2=8[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-5}{2-1}\\Slope=\frac{3}{2}[/tex]
So, we get slope [tex]m=\frac{3}{2}[/tex]
Finding y-intercept
y-intercept can be found using slope [tex]m=\frac{3}{2}[/tex] and point (1,5)
[tex]y=mx+b\\5=\frac{3}{2}(1)+b\\b=5- \frac{3}{2}\\b=\frac{10-3}{2}\\b=\frac{7}{2}\\[/tex]
So, we get y-intercept [tex]b=\frac{7}{2}[/tex]
Equation of line
So, equation of line having slope [tex]m=\frac{3}{2}[/tex] and y-intercept [tex]b=\frac{7}{2}[/tex] is:
[tex]y=mx+b\\y=\frac{3}{2}x+\frac{7}{2}[/tex]
The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]

Christian opened a savings account with $3250. His account will earn 5.2% simple interest.
How much money will be in his account after 6 years?
Answers
The total amount of money will be in his account after 6 years is $4264.
Given that, principal = $3250, rate of interest = 5.2% and time period = 6 years.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.
Substitute P=$3250, R=5.2% and T=6 years in simple interest formula
That is, S.I. = (3250 × 5.2 × 6)/100
= $1014
Amount = Principal + Simple interest
= 3250 + 1014
= $4264
Therefore, the total amount of money will be in his account after 6 years is $4264.

7(3x + 5) - x = 75
Answers
Answer:
x = 2
Step-by-step explanation:
7(3x + 5) - x = 75
1. Distributive property
multiply 7 by whatever is in the parenthesis
7*3x + 7*5 - x = 75
21x + 35 - x = 75
2. Combine like terms
21x - x = 20x
20x + 35 = 75
3. Subtract 35 on both sides
20x + 35 - 35 = 75 - 35
20x = 40
4. Divide both sides by 20 since u want to isolate the variable
20x/20 = 40/20
x = 2
And thats ur answer
Hope this helped!
