The students will colour the 1/8th part of the sheet given to them by their teacher.
What is a fraction?The fraction is defined as the division of the whole part into an equal number of parts.
Given that:-
The art teacher, ms. garcia gave each student half a sheet of paper. then she asked the students to colour one-fourth of their sheets of paperNow the sheet student have = 1 / 2
Students will colour 1/4th of the sheet they have = ( 1/2 x 1/4 )
= 1 / 8

Answer:
∠ABC = 55°
Step-by-step explanation:
Alternate Interior Angles Theorem
If a line (AC) intersects a set of parallel lines (m and n) in the same plane at two distinct points, the alternate interior angles that are formed are congruent.
⇒ ∠BAC = ∠DCA
⇒ ∠BAC = 50°
The interior angles of a triangle sum to 180°
⇒ ∠BCA + ∠BAC+ ∠ABC = 180
⇒ 75 + 50 + ∠ABC = 180
⇒ ∠ABC = 180 - 75 - 50
⇒ ∠ABC = 55°

In this figure: the value of “y” that makes the quadrilateral “A B C D” a parallelogram is:
Answer:
y = 10
Step-by-step explanation:
if the figure is to be a parallelogram, then
∠ ACB and ∠ DAC are alternate angles and are congruent , that is
5y - 13 = 7 + 3y ( subtract 3y from both sides )
2y - 13 = 7 ( add 13 to both sides )
2y = 20 ( divide both sides by 2 )
y = 10

Line v passes through points (10, 9) and (1, 13). Line w is perpendicular to v. What is the slope of line w?
Answer:
9 / 4
Step-by-step explanation:
The slope of line V can be found using the formula for slope: (y2 - y1) / (x2 - x1).
(y2 - y1) / (x2 - x1)
(13 - 9) / (1 - 10)
(4) / (-9)
Two slopes are perpendicular when the values are reciprocals. The slope of line V is 4 / (-9). The reciprocal of this is: 9 / 4.

A high-interest savings account pays 5.5% interest compounded annually. if $300 is deposited initially and again at the first of each year, which summation represents the money in the account 10 years after the initial deposit? sigma-summation underscript n = 1 overscript 10 endscripts 300 (0.055) superscript n minus 1 sigma-summation underscript n = 1 overscript 10 endscripts 305.5 (1.055) superscript n minus 1 sigma-summation underscript n = 1 overscript 10 endscripts 316.5 (0.055) superscript n minus 1 sigma-summation underscript n = 1 overscript 10 endscripts 316.5 (1.055) superscript n minus 1
The summation that represents the money in the account 10 years after the initial deposit is P(10) = 300(1.055)^10
Exponential equationsExponential equations are equations that increase geometrically
The formula for calculating the compound. interest is expressed as:
P(t) = P0(1+r)^t
Given the following
P0 =. $300
r = 5.5% = 0.055
t = 10years
Substitute
P(10) = 300(1+0.055)^10
P(10) = 300(1.055)^10
Hence the summation that represents the money in the account 10 years after the initial deposit is P(10) = 300(1.055)^10

Solve the following equation for b.
13b=6b+14
[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}[/tex]
❖ First of all, we need to make sure that all the variables are on one side (the left-hand side, LHS) and numbers are on the right-hand side, RHS.
Here we have variables on the right-hand side, so we can move that term to the left-hand side, making sure to use the opposite operation:-
13b=6b+14 Subtract 6b on both sides, which results in:-
7b=14 Divide by 7 on both sides, which results in:-
b=2 We've found the value of b. Now, we need to check our solution by replacing b with the value of b, 2, and seeing whether or not we end up with a true statement:-
13(2)=6(2)+14 Multiply.
26=12+14 Now add.
26=26 Since the left-hand side does equal the right-hand side, we conclude that our solution, b=2, is correct.

Select the correct expressions. 1 Identify each expression that represents the slope of a tangent to the curve y= * +1 at any point (x, y)
The expressions which represents the slope of a tangent to the curve [tex]y=\frac{1}{x+1}[/tex] at any point (x, y) are:
[tex]f'(x) =limh \rightarrow 0\frac{-h}{h(x+1)(x+h+1)}\\\\f'(x) =limh \rightarrow 0\frac{-h}{x^2h+2xh+xh^2+h^2 +1}[/tex]
The slope of a tangent to the curve.Mathematically, the slope of a tangent line to the curve is given by this equation:
[tex]f'(x) =limh \rightarrow 0\frac{f(x+h)-f(x)}{h}[/tex]
Given the function:
[tex]f(x)=y=\frac{1}{x+1}[/tex]
When (x + h), we have:
[tex]f(x+h)=y=\frac{1}{x+h+1}[/tex]
Next, we would find the derivative of f(x):

two boys decided to buy a computer. The second boy had 5/6 of the amount of money the first had. The first boy had 7/8 of the price of the computer. Together they had $696 more than they needed to pay. What was the price of the computer
Answer:
1152$
Step-by-step explanation:
b1 = 7/8 C
b2 = 5/6 b1 = 35/ 48 C
7/8 C + 35/48 C = C + 696
42/48 C + 35/48 C = 48/48 C + 696 * 48/48
(42 + 35 - 48 ) C = 696 * 48
29 C = 33408
C =1152.

Book-club members are required to buy a minimum number of books each year. Leslee bought 3 times the minimum. Denise bought 7 more than the minimum. Together, they bought 23 books. What is the minimum number of books?
Answer: 4 books
Step-by-step explanation:
x = minimum number of book
Leslee
= 3x (bought 3 times the minimum)
Denise
= x + 7 (bought 7 more than the minimum)
Together
= (3x) + (x + 7)
(3x) + (x + 7) = 23 (books they bought together)
3x + x + 7 = 23
3x + x = 23 - 7 (isolate the like variables together)
4x = 16 (divide both sides by 4)
x = 4
4 is the minimum number of books
To check:
