Las longitudes de las diagonales son √41 dm y 10 cm respectivamente
La medida de la diagonal de un rectángulo: de lado l1 y l2 es igual a
d² = (l1)² + (l2)²
La diagonal entonces es: utilizamos la fórmula dadas para los lados dados y aplicando raíz en la ecuación
A. 5dm y 4dm
d = √((5 dm)² + (4 dm)²) = √(25 + 16) dm = √41 dm
B. 8cm y 6cm
d = √((8 cm)² + (6 cm)²) = √(64 + 36) cm = √100 cm = 10 cm .

What is the summation notation for the geometric series 1/2+2 + 8 +32+128
Answer:
D
Step-by-step explanation:
Edge
The summation of the given geometric series is 70.5.
What is geometric series ?
Geometric series is the sum of an infinite number of terms that have a constant ratio between the successive terms.
Formula for the sum of the nth term of a geometric series[tex]s_{n}= a\frac{(r^{n} -1)}{(r-1)}[/tex] (when r>1)
or
[tex]S_{n} =\frac{a(r^{n}-1) }{1-r}[/tex] (when r<1)
where,
r is the common ratio
a is the first term of first term of the series.
n is the total number of terms.
According to the given question
we have
geometric series [tex]\frac{1}{2} +2+8+32+128[/tex]
total number of terms, n=5
first term a =[tex]\frac{1}{2}[/tex]
[tex]r=\frac{2}{\frac{1}{2} }=4[/tex]
therefore,
summation of the given geometric series calculated as
[tex]s_{n} =\frac{1}{2} \frac{4^{5}-1 }{4-1}[/tex]
[tex]s_{n} =\frac{1023}{6}[/tex]
[tex]s_{n} = 170.5[/tex]
Hence, the summation of the geometric series is 170.5.

If two numbers HCF is 5 and LCM is 60. One number is 15 then what is the second number
Answer:
LCM x HCF = Product of the two numbers.
Step-by-step explanation:
HCF = 5
LCM = 60
Therefore, 5 x 60 = 15x the other number.
300 = 15x the other number
the other number = 300/15
The other number = 20

At a coffee shop, the first 100 customers'
orders were as follows.
Small
Medium
Large
Hot
5
48
22
Cold
8
12
5
What is the probability that a customer ordered
a medium given that he or she ordered a cold drink
Answer:
12%
Step-by-step explanation:
P(cold, med) = 25/100 x 12/25 = 12/100 or 12%
The probability that a customer ordered a small given that he or she ordered a cold drink is, 32%
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Since, The probability is represented as:
P(Small | Cold)
This is calculated using:
P(Small | Cold) = n(Small and Cold)/n(Cold)
Using the data on the given table, we have:
P(Small | Cold) = 8/(8 + 12 + 5)
Evaluate
P(Small | Cold) = 0.32
Express as percentage
P(Small | Cold) = 32%
Hence, the probability that a customer ordered a small given that he or she ordered a cold drink is 32%

Jessica made 6 19/20 cups of punch. Her punch had two different types of juices in it. If the lunch had 4 1/5 cups of one type of juice, how many cups of the other type of juice did it have?
Answer:
2 3/4 cups
Step-by-step explanation:
Jessica made 6 19/20 cups of punch. Her punch had two different types of juices in it. If the lunch had 4 1/5 cups of one type of juice, how many cups of the other type of juice did it have?
We solve this question using the Subtraction operation
Total cups = cups of first type of juice + cup of other type of juice
6 19/20 = 4 1/5 cups + x
x = 6 19/20 - 4 1/5 cups
Lowest Common Denominator = 20
x = 6 - 4 + (19/20 - 1/5)
x = 2 + (19 - 4/20)
x = 2 15/20 cups
x = 2 3/4 cups
Other type of juice had 2 3/4 cups of juice

8 yd
2 yd
Answer:
2 * 8 for the first section, and then the last one is 16.
Step-by-step explanation:
area for a parallelogram is base times height.
8 yd is the height, 2 yd is the base. so 2 would be that first blank.
second blank is 16, simply cause 2 * 8 = 16.

3(−4)=12x What is the value of ?
Answer:
x = -1
Step-by-step explanation:
When given the following equation:
3(-4) = 12x
Simplify the left, side to perform the given operations. Remember, when there are parentheses but no operations between the two parentheses, then the operation is mutliplciation.
-12 = 12x
Inverse operations, divide both sides by (12) to undo the operation on the left side,
-1 = x
Answer:
as there is a braket add the distributive law soo it will be -12=12x and rhen u will move the the 12 from x to the other side of the equation u dived it with -12 so u

The price of 2 ratios are in x:y when the prices both increase by £20, the ratio becomes 5:2 when the prices both reduce by £5 the ratio becomes 5:1 express the x:y ratio in the lowest form
Answer:
x:y = 4:1
Step-by-step explanation:
Since their ratios are x:y, when they both increase by £20, their ratio is 5:2.
So, x + 20/(y + 20) = 5/2 (1)
When they both decrease by £5, their ratio is 5:1.
So, x - 5/(y - 5) = 5/1 (2)
Simplifying (1) and (2), we have
x + 20/(y + 20) = 5/2 (1)
cross-multiplying, we have
2(x + 20) = 5(y + 20)
expanding the brackets, we have
2x + 40 = 5y + 100
2x - 5y = 100 - 40
2x - 5y = 60 (3)
So,
x -5/(y - 5) = 5/1 (2)
cross-multiplying, we have
(x - 5) = 5(y - 5)
expanding the brackets, we have
x - 5 = 5y - 25
x = 5y - 25 + 5
x = 5y - 20 (4)
Substituting (4 into (3), we have
2x - 5y = 60 (3)
2(5y - 20) - 5y = 60
10y - 40 - 5y = 60
10y - 5y = 60 + 40
5y = 100
y = 100/5 = 20
substituting y = 20 into (4), we have
x = 5y - 20 (4)
x = 5(20) - 20
x = 100 - 20
x = 80
So, x/y = 80/20 = 4
x/y = 4/1
x:y = 4:1
solve for x

Answer:
128/15 min or 8.5 min
Step-by-step explanation:
By using unitary method,
Time required to paint 5/8 of wall = 16 min.
Time required to paint 1/1 of wall = 16*8/5
Hence, Time required to paint 1/3 of wall = 16*8/5*1/3

3x + 5 = 2x -17
Solve it and show the work because i need to show the work
Answer:
x = -22
Step-by-step explanation:
Subtract 5 from both sides
3x + 5 (-5) = 2x - 17 (-5)
3x = 2x - 17
Subtract 2x from both sides
3x (-2x) = 2x (-2) -22
x = -22

Step-by-step explanation:
A fishbowl shaped like a sphere is filled with water. The fishbowl has a diameter of 16 inches. Which measurement is closet to the volume of water in the fishbowl in cubic inches?
Volume of a sphere = 4/3πr³
Diameter = 16 in
Radius = Diameter/2 = 16 in/2 = 8 in
Volume of a Sphere = 4/3 × π × 8³
= 2144.66 cubic Inches
