A shape is made of 9 right triangles of equal size and three identical rectangles.
Each rectangle measures 7 mm wide by 3 mm high. The rectangles are each
7 mm wide by 3 mm high. What is the total area, in square millimeters,
of the shape?
Answers
Answer:
The area of the figure is 157.5 square millimeters.
Step-by-step explanation:
Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:
Area of a rectangle: base x height
Area of a triangle: (base x height) / 2
7x3 = 21 = Rectangle area
7x3 / 2 = 10.5 = Triangle area
21 x 3 + 10.5 x 9 = 157.5
Thus, the area of the figure is 157.5 square millimeters.

Draymond has $10.00 for lunch. He and his friend order pizza for $6,90 and two drinks for $1.50 each. Does he have enough money? Explain how you know below for full credit.
Answers
Answer:
yes. the total when added together is $9.90, meaning that he has just enough for them to get a pizza and one drink each.
Step-by-step explanation:
6.90
1.50
1.50
9.90
Answer:
Yes, he has enough money.
Step-by-step explanation:
He will have .10 left over. The pizza is $6.90 and the drinks are $1.50 each.
1.50 + 1.50 = 3.00
6.90 + 3.00 = 9.90
He spends $9.90, so he will be 10 cents short of spending all of his lunch money. Therefore, he has enough money.

Answer:
240
Step-by-step explanation:
The generic k-th term of the expansion of the binomial ...
(a +b)^n
is given by ...
(nCk)a^(n-k)b^k . . . . . where nCk = n!/(k!(n-k)!) and 0 ≤ k ≤ n
For this problem, we have ...
a=2x, b=y, n=6, k=2
Then the 2nd term (counting from 0) is ...
6C2×(2x)^4×y^2 = (6·5)/(2·1)·16x^4·y^2
= 240x^4y^2
The desired coefficient is 240.

Additional comment
The coefficients for the expansion match the numbers in a row of Pascal's triangle. The row beginning with 1, n will have the coefficients for the expansion to the n-th power.

Miguel compró 253 Kilos de pescado para venderlo en su negocio, si decide vender cada kilo de pescado en Bs 1.900.000. Entonces, ¿Cuánto dinero recaudó en total por la venta del pescado?
Answers
Answer:
Miguel recaudó Bs 480.700.000 por la venta del pescado.
Step-by-step explanation:
Con la información proporcionada puedes calcular el dinero que recaudó en total por la venta del pescado multiplicando el precio de venta de cada kilo de pescado por el número de kilos que Miguel compró:
Número de kilos comprados=253
Precio de venta por kilo=1.900.000
Total vendido=253*1.900.000
Total vendido=480.700.000
De acuerdo a esto, la respuesta es que Miguel recaudó Bs 480.700.000 por la venta del pescado.
4. Write the ratio 25c to R3,50 in its simplest form.
Answers
Answers:
25c= 1/2
Then R3.50 is 3/50
Step-by-step explanations:
25c as a fraction is 25/50, so you have to simplify 25/50 to its simplest form , and you get the result of 1/2
For this you have to first find the GCD (or HCF) of numerator and denominator. GCD of 3 and 50 is 1.
3 ÷ 150 ÷ 1.
Reduced fraction: 350. Therefore, 3/50 simplified to lowest terms is 3/50.

While attending a major league baseball game, you think you can guess the
attendance within 10% of the actual value. If the announced attendance is
35,000, within what number of people would your guess have to be in order for you to support your claim?
Answers
Answer:
You would have to have guess a number larger than 31500 and smaller than 38500
Step-by-step explanation:
The answer will look something like
35000 +/- 10% (35000)
What that means is that the attendance would be smaller than 35000 or larger than 35000.
10% * 35000 = 10/100 * 35000 = 350000 / 100 = 3500
So you would have to estimate
35000 - 3500 ≤ attendance ≤35000 + 3500
31500 ≤ attendance ≤ 38500

x⁰ = 360 degree- ( 246⁰ + 66⁰)
= 360 degree- 312⁰
= 48 ⁰
Answer:
x = 114
Step-by-step explanation:
Remark
You are trying to figure out what the arc is in degrees. The arc formula is
Intersect angle = 1/2( the furthest arc - the smaller closer arc).
Givens
Intersect angle = 66 degrees
Closer arc = x
Further or largest Arc = 246
Solution
66 = 1/2 (246 - x) Multiply both sides by 2 and remove the brackets.
132 = 246 - x Subtract 246 from both sides.
132 - 246 = - x
- 114 = - x Multiply both sides by -1
-1 (-114) = -1 * (-x)
x = 114

Harriet had a remote control car every 4/15 of a second the remote control car travels 4/5 of a foot how many feet per second does the remote control car travel
Answers
Answer:
3 ft/s
Step-by-step explanation:
The rate or speed of the remote control car, v = distance/time
Now, the distance travelled by the remote control car = 4/5 of a foot = 4/5 × 1 ft = 4/5 ft and the time it takes to cover this distance is 4/15 of a second = 4/15 × 1 s = 4/15 s.
So, v = distance/time
= 4/5 ft ÷ 4/15 s
= 4/5 ft × 15/4 s
= 3 ft/s
If a fair coin is tossed 6 times, what is the probability, rounded to the nearest thousandth, of getting at least 3 heads?
ANSWER IS 0.656
Answers
Answer:
Step-by-step explanation:
For each outcome there are
s!/(n!(s-n)!) combinations
where s is the number of selections and n is the number of specific outcomes
The probability of any specific outcome for 6 tosses of a coin is (1/2)^6
[(1/2)^6]*[(6!/6!)+(6!/(5!)+(6!/(4! 2!)+(6!/(3! 3!)]
(1/2)^6*(1+6+15+20)
42(1/2)^6
42(1/64)
42/64
21/32 which is 0.65625
