What is the area of triangles in square yards
Answer:
37.625 square yards or 37⅝ square yards
Step-by-step explanation:
Area of the triangle = ½*base*height
Where,
base = 10¾ yd = 10.75 yds
height = 7 yds
Substitute the value of each variable into the equation:
Area = ½*10.75*7
Area = 37.625 square yards or 37⅝ square yards

If a car traveling 40 miles per hour takes 50
feet to stop, then accurate to the nearest
tenth, how many seconds will it take to stop?
Answer:
t = 0.85 s
Step-by-step explanation:
Given that,
The speed of a car, v = 40 mph = 17.8816 m/s
Distance, d = 50 feet = 15.24 m
Let the time be t. The formula for speed is given by distance divided by time. So,
[tex]v=\dfrac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{15.24 }{17.8816 }\\\\t=0.85\ s[/tex]
So, the required time is 0.85 s.

Match the expressions on the left with the right
(a) 21 in by 15 in
Calculate area
[tex]Area = 21in * 15in[/tex]
[tex]Area = 315in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 315in^2 * \frac{1}{3}[/tex]
[tex]1-third = 105in^2[/tex]
Hence:
[tex](21in,15in)=>105in^2[/tex]
(b) 21 in by 30 in
Calculate area
[tex]Area = 21in * 30in[/tex]
[tex]Area = 630in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 630in^2 * \frac{1}{3}[/tex]
[tex]1-third = 210in^2[/tex]
Hence:
[tex](21in,30in)=>210in^2[/tex]
(c) 15 in by 18 in
Calculate area
[tex]Area = 15in * 18in[/tex]
[tex]Area = 270in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 270in^2 * \frac{1}{3}[/tex]
[tex]1-third = 90in^2[/tex]
Hence:
[tex](15in,18in)=>90in^2[/tex]
(d) 15 in by 30 in
Calculate area
[tex]Area = 15in * 30in[/tex]
[tex]Area = 450in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 450in^2 * \frac{1}{3}[/tex]
[tex]1-third = 150in^2[/tex]
Hence:
[tex](15in,30in)=>150in^2[/tex]

Answer:
B. 48 cm²Step-by-step explanation:
The area between the concentric circles:
A = π(R² - r²)If we tale π ≈ 3, we know R = 5 cm, we see r = R - 2 = 5 - 2 = 3 cm, then
A = 3(5² - 3²) = 3(16) = 48 cm²Correct choice is B
Books are identified by an International Standard Book Number (ISBN), a 10-digit code x1 x2...x10, assigned by the publisher. These 10 digits consist of blocks identifying the language, the publisher, the number assigned to the book by its publishing company, and finally, a 1-digit check digit that is either a digit or the letter X (used to represent 10). This check digit is selected so that \sum_{i=1}^{10} ix_i \equiv 0 \text{ mod } 11 and is used to detect errors in individual digits and transposition of digits.
a. The ISBN for a book is 1-32-794182- Q} where Q is the check digit. What is Q?
b. The ISBN of another book is 2-429-39M18-6. Find the digit M.
Answer:
[tex]Q = 1[/tex]
[tex]M = 2[/tex]
Step-by-step explanation:
Solving (a):
Given: 1-32-794182- Q
Required: Find Q
To do this, we first multiply each digit in descending order of 10.
So, we have:
[tex]Product = 1 * 10 + 3 * 9 + 2 * 8 + 7 * 7 + 9 * 6 + 4 * 5 + 1 * 4 + 8 * 3 + 2 * 2 + Q * 1[/tex]
[tex]Product = 208 + Q *1[/tex]
[tex]Product = 208 + Q[/tex]
Equate the modulus of the product by 11 to 0
[tex]Product \% 11 = 0[/tex]
[tex](208 + Q) \% 11 = 0[/tex]
The next number greater than 208 divisible by 11 is 209.
So, we have:
[tex](208 + Q) \% 11 = 209 \% 11[/tex]
Express 209 as 208 + 1
[tex](208 + Q) \% 11 = (208 + 1)\% 11[/tex]
By comparison:
[tex]Q = 1[/tex]
Hence, the checksum is 1
Solving (a):
Given: 2-429-39M18-6
Required: Find M
Apply the same step in (a)
So, we have:
[tex]Product = 2 * 10 + 4 * 9 + 2 * 8 + 9 * 7 + 3 * 6 + 9 * 5 + M * 4 + 1 * 3 + 8 * 2 + 6 * 1[/tex]
[tex]Product = 198 + 4M + 25[/tex]
[tex]Product = 223+ 4M[/tex]
Equate the modulus of the product by 11 to 0
[tex]Product \% 11 = 0[/tex]
[tex](223+ 4M) \% 11 = 0[/tex]
The next number greater than 223 divisible by 11 is 231.
So, we have:
[tex](223+ 4M) \% 11 = 231 \% 11[/tex]
Express 231 as 223 + 8
[tex](223+ 4M) \% 11 = (223 + 8) \% 11[/tex]
By comparison:
[tex]4M = 8[/tex]
Divide both sides by 4
[tex]M = 2[/tex]

[tex]\huge\boxed{\sf Rhombus}[/tex]
Step-by-step explanation:
When we plot the given vertices on a graph, We get a shape which has the following characteristics.
=> Opposite angles are equal.
=> The diagonals are perpendicular to each other.
=> Opposite sides are parallel to each other.
=> Sum of adjacent angles in equal to 90 degrees.
But, the shape does not seem to be like pentagon, square and rectangle. Hence, It's a rhombus.
