Answer:
4/3 kg
Step-by-step explanation:
Let x represent a half brick, let y represent a 1 brick.
We know that 1 brick and 1/2 brick weigh 1 kg. so we represent this as
[tex]x + y = 1[/tex]
We know that obviously x is half of y. so
[tex]x = \frac{1}{2} y[/tex]
Subsitur this for x.
[tex] \frac{1}{2} y + y = 1[/tex]
[tex] \frac{3}{2} y = 1[/tex]
[tex] y = \frac{2}{3} [/tex]
This means one block weight 2/3 kg. So how much 2 weigh.
[tex] \frac{2}{3} \times 2 = \frac{4}{3} [/tex]

hi these are geometry questions, :)
========================================================
Explanation:
For any inscribed quadrilateral like this, the opposite angles are always supplementary. This means the angles add to 180
B+D = 180
(2x-1) + (3x-59) = 180
(2x+3x) + (-1-59) = 180
5x-60 = 180
5x = 180+60
5x = 240
x = 240/5
x = 48
Use this x value to find angle A
A = 2x+4
A = 2*48+4
A = 96+4
A = 100
This then means,
A+C = 180
C = 180-A
C = 180-100
C = 80 degrees
Side note: The term "cyclic quadrilateral" is the same as "inscribed quadrilateral".

What makes a trapezoid an isosceles trapezoid
Answer:
A trapezoid is a quadrilateral with exactly one pair of parallel sides. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.
The cost price of a box and a pen is Rs 120. The box is sold at 10% profita the pen is sold at 10% loss. If the selling price of the box is Rs 52 more than of the pen, calculate the profit or loss percent in the whole.
Answer:
3.803% Profit
Step-by-step explanation:
First let us calculate total sales, then calculate the total cost, and then divide the two.
Sale: 120*1.1=132 and 52*.9=46.8
Cost: 120 and 52
Profit equation:
[tex]\frac{Net sales-COGS}{Net Sales} =Profit[/tex]
[tex]\frac{(132+46.8)-(120+52)}{(132+46.8)}[/tex]
Simplify:
[tex]\frac{6.8}{178.8} =.03803[/tex] or 3.803% Profit
An American sausage is 4/3 inches long. How many pieces of sausage can be cut from the 4/3 inch piece of sausage if each piece is two-thirds of an inch?
Answer:
2 Pieces can be cut
Step-by-step explanation:
We know that our sausage is 4/3 inches and we want to know how many 2/3 pieces can be cut. we start by examining our fractions.
4/3 & 2/3, since they have the same denominator we can simply divide the total length by how big each cut should be!
4/3 ÷ 2/3 = 2

find the range. 130,131,132,134,135136,137,138,139,141,142,143,144,146,148,146,149,158,169
Answer:
The answer is 12
Step-by-step explanation:
The range is the difference between the lowest and highest values. In this case, this means 142 - 130 which equals 12.
Answer:
12
Step-by-step explanation:
Range = Largest number - Smallest number
Larger number = 142 ; Smallest number = 130
142-130 = 12
Range = 12
A cash register at a store contains $277 bills. There are six more $5 bills than $10 bills. The number of $1bills is two more than 24 times the number of $10 bills. How many bills of each kind are there
Answer: See explanation
Step-by-step explanation:
Your question isn't well written, the store contains $227 and not $277.
let c be the number of $1 bills
let f be the number of $5 bills
let t be the number of $10 bills.
Therefore, the equation will be:
1c + 5f + 10t = 227
Since there are six more $5 bills than $10 bills, therefore,
f = t+6
Also, the number of $1 bills is two more than 24 times the number of $10 bills and this will be:
c = 24t + 2
Now, we substitute the equation for f and c into the main equation and this will be:
1c + 5f + 10t = 277
1(24t + 2) + 5(t + 6) + 10t = 227
24t + 2 + 5t + 30 + 10t = 227
39t + 32 = 227
39t = 227 - 32
39t = 195
t = 195/39
t = 5
Therefore, there are 5 $10 bills
Since c = 24t + 2
c = 24(5) + 2
c = 120 + 2
c = 122
Therefore, there are 122 $1 bills
Since f = t+6
f = 5+6
f = 11
Therefore, there are 11 $5 bills.
Line r is parallel to line c.

D. $512,68
9514 1404 393
Answer:
A. $674.43
Step-by-step explanation:
The account balance is given by ...
A = P(1 +r/12)^(12t) . . . . . principal P invested at annual rate r for t years
A = $500(1 +0.06/12)^(12·5) = $500(1.005^60)
A ≈ $674.43
Please solve this problem 9p-10=6+p?
Answer:
p=2
Step-by-step explanation:
9p-10=6+p
Subtract p from each side
9p-p-10=6+p-p
8p -10 =6
Add 10 to each side
8p -10+10 =6+10
8p =16
Divide each side by 8
8p/8 = 16/8
p =2
Answer:
p = 2
Step-by-step explanation:
1. 9p - 10 = 6 + p
2. 8p - 10 = 6
3. 8p = 16
4. p = 2

If triangle LMQ is similar to triangle LNP, calculate the length of segment LP.
Answer:
LP = 15
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{LM}{LN}[/tex] = [tex]\frac{LQ}{LP}[/tex] , substitute values
[tex]\frac{4}{10}[/tex] = [tex]\frac{LQ}{LQ+QP}[/tex]
[tex]\frac{2}{5}[/tex] = [tex]\frac{LQ}{LQ+9 }[/tex] ( cross- multiply )
5LQ = 2(LQ + 9) = 2LQ + 18 ( subtract 2LQ from both sides )
3LQ = 18 ( divide both sides by 3 )
LQ = 6
Then
LP = LQ + QP = 6 + 9 = 15
state the dimensions of the matrix. identify the indicated element
Answer:
D; 2 * 3; -4
Step-by-step explanation:
The dimension of the matrix refers to the number of elements in a row multiplied by the number of elements is a column
In a row, we have 2 elements, in a column , we have 3 elements
So the matrix is of 2 * 3 dimension
a21, refers to the element in the matrix that is in the row 2 column 1 and that is -4

Pedro signed up for a streaming music service that costs $13 per month. The service
allows Pedro to listen to unlimited music, but if he wants to download songs for
offline listening, the service charges $0.75 per song. How much total money would
Pedro have to pay in a month in which he downloaded 45 songs? How much would he
have to pay if he downloaded s songs?
Cost with 45 songs:
Cost with s songs:
Answer:
Cost with 45 songs: $46.75
Cost with s songs: $13 + (s * $0.75)
Step-by-step explanation:
First multiply the number of songs by the cost per song (45 * $0.75 = $33.75), then add the monthly service cost to that number ($13 + $33.75 = $46.75) to get the total monthly cost to Pedro.

Answer:
7/3-3y = 7/3x - 3Step-by-step explanation:
1) The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-3))/(3 -0) = 7/3
__
2) The y-intercept is the point where x=0:
(x, y) = (0, -3) . . . . . y = -3
__
3) Then the slope-intercept equation is ...
y = mx + b . . . . . . . line with slope m and y-intercept b
y = 7/3x -3
