14:56 as a simplified ratio
Answer:
1:4
Step-by-step explanation:
To represent 14:56 as a simplified ratio, we need to reduce it by finding the GCF (greatest common factor) and dividing it by both terms.
The GCF of 14 & 56 is 14.
14 / 14 = 1
56 / 14 = 4
Thus we are left with our new simplified ratio, 1:4.

Given :-Here, we have composite figure which is composed of 2 cuboids. The dimensions of larger cuboid is 12cm, 7cm, 7cmThe dimensions of smaller cuboid is 7cm, 2cm , 2cmTo Find :-We have to find the total surface area of the composite figure Let's Begin :-Here,
The dimension of larger cuboid are
Length = 12cmBreath = 7 cmheight = 7 cmWe know that,
Lateral surface area of cuboid
[tex]\bold{\red{ = 2( lb + bh + hl)}}[/tex]
Subsitute the required values,
[tex]\sf{ = 2[(7)(7) + (7)(12) +(7)(12) ]}[/tex]
[tex]\sf{ = 2[ 49 + 84 ]}[/tex]
[tex]\sf{ = 2[ 49 + 168 ]}[/tex]
[tex]\sf{ = 2[ 217 ]}[/tex]
[tex]\bold{ = 434 cm^{2}}[/tex]
Now,We have to find the lateral surface area of smaller cuboid
The dimensions of smaller cuboid are 7cm, 2cm and 2cmTherefore,
Lateral surface area of smaller cuboid
[tex]\sf{ = 2[(2)(7) + (7)(2) +(2)(2) ]}[/tex]
[tex]\sf{ = 2[ 14 + 14 + 4 ]}[/tex]
[tex]\sf{ = 2[ 28 + 4 ]}[/tex]
[tex]\sf{ = 2[ 32]}[/tex]
[tex]\bold{ = 64 cm^{2}}[/tex]
The common base area of both the cuboids
[tex]\sf{ = lb }{\sf{ + lb}}[/tex]
[tex]\sf{ = 14 + }{\sf{ 14}}[/tex]
[tex]\bold{ = 28 cm^{2}}[/tex]
Now,The total surface area of the given composite figure
= SA of larger cuboid + SA of smaller cuboid - common base area
Subsitute the required values,
[tex]\sf{ = 434 + 64 - 28 }[/tex]
[tex]\sf{ = 498 - 28 }[/tex]
[tex]\bold{ = 470cm^{2}}[/tex]
Hence, The surface area of composite figure is 470 cm² .

A running shoe store mounts a new promotional campaign. Purchasers of new shoes may, if dissatisfied for any reason, return them within 7 days of purchase and receive a full refund. The cost to the dealer of such a refund is $105. The dealer estimates that with an 11% probability each purchaser, for whatever reason, will return their pair of shoes and obtain refunds. Suppose that 120 pairs of shoes are purchased during the campaign period. Clearly the exact number of purchasers who return their product is unknown. Answer the following questions:
a. Describe the probability distribution of the number of pairs of shoes that will be returned for refunds.
b. What is the mean and standard deviation of the number of pairs of shoes that will be returned for refunds.
c. What is the mean and standard deviation of the total refund costs that will accrue as a result of these refunds.
Answer:
a
[tex]P(K = k ) = \ ^nC_x * p^k * (1-p)^{n-k}[/tex]
Here k is the random number of number of pairs of shoes that will be returned for refund, which can be k = 0,1 ,2,3,4 ..., 120
b
The mean is [tex]E(K) = np = 13.2[/tex]
The standard deviation is [tex]\sigma = 3.43[/tex]
c
The mean is [tex]E(C) = E(105 K) = 1386[/tex]
The standard deviation is [tex]\sigma = 381.48 [/tex]
Step-by-step explanation:
From the question we are told that
The cost to dealer for each refund is [tex]C = \$105[/tex]
The probability that a shoe will refunded is [tex]P(x) = 0.11[/tex]
The number of shoes purchased is n = 120 pairs
Generally the probability distribution of the number of pairs of shoes that will be returned for refunds is
[tex]P(K = k ) = \ ^nC_x * p^k * (1-p)^{n-k}[/tex]
Here k is the random number of number of pairs of shoes that will be returned for refund, which can be k = 0,1 ,2,3,4 ..., 120
Generally the mean is mathematically represented as
[tex]E(K) = np = 120 * 0.11[/tex]
=> [tex]E(K) = np = 13.2[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{ n* p (1-p)}[/tex]
=> [tex]\sigma = \sqrt{ 120* 0.11 (1-0.11)}[/tex]
=> [tex]\sigma = 3.43[/tex]
Generally the total refund cost is mathematically represented as
[tex]C = 105 K[/tex]
Here K denotes the number of shoes returned
Generally the mean of the total refund cost is mathematically represented as
[tex]E(C) = E(105 K) = 105 E(K)[/tex]
=> [tex]E(C) = E(105 K) = 105 * 13.2[/tex]
=> [tex]E(C) = E(105 K) = 1386[/tex]
Generally the variance of the total refund cost is mathematically represented as
[tex]Var(K) = 105^2 * E(K)[/tex]
=> [tex]Var(K) = 105^2 * 13.2[/tex]
=> [tex]Var(K) = 145530[/tex]
=> [tex]\sigma = \sqrt{145530 }[/tex]
=> [tex]\sigma = 381.48 [/tex]

The angles opposite the congruent sides of an isosceles triangle are congruent. Find the value of x in the triangle. Show all your work.
The figure shows a triangle with 2 congruent sides. The angle between the congruent sides measures x degrees and a different angle measures 70 degrees.
Answer:
40
Step-by-step explanation:
Angles opposite congruent sides in a triangle are congruent, so the other base angle is also 70 degrees.
This means that the interior angles are 70, 70, and x
Since the sum of the measures of the angles of a triangle is 180 degrees,
70+70+x=180
140+x=180
x=40
Farmland A farmer has a rectangular plot of land shaped like the figure in the graph. There is another identical plot of land 100 yards east and 120 yards north of the original plot. Graph both plots of land. Then find the combined area of the two plots of land
The graph of both plots would be the one graph in option C.
Combined area = 2(area of one rectangular plot) = 720 sq. yds.
What is the Area of a Rectangular Shape?Area of a rectangular shape = length × width
From the graph given, 1 unit represents 20 yards. Therefore:
100 yards east of the original plot is going to be 5 units to the left on the x-axis.120 yards north of the original plot would be 6 units upwards on the y-axis.Therefore, the graph of both plots would be the one given in option C.
The plot is rectangular in shape having 60 yards × 60 yards. Therefore:
Area of 1 plot = length × width = 60 × 60 = 360 square yards.
Combined area = 2(area of one rectangular plot) = 2(360) = 720 sq. yds.

What is the volume of the triangular prism? *
Pleaseeeee answer
Answer:
360 ft³Step-by-step explanation:
The formula for calculating the volume of a right triangular prism is:
(1/2 x b x h) x lLet's use the formula to calculate the volume of the right triangular prism.
(1/2 x 15 x 6) x 8⇒ (15 x 3) x 8⇒ 45 x 8⇒ 360 ft³First, rewrite 5/7 and 8/11 so that they have a common denominator.
common denominator = 7x11 = 77
5/7 = (5x11) / (7x11) = 55/77
and
8/11 = (8x7) / (11x7) = 56/77
5/7 and 8/11 can be rewritten as 55/77 and 56/77, respectively, so that they have a common denominator of 77.
What is a fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
To rewrite 5/7 and 8/11 with a common denominator:
We can find the least common multiple (LCM) of the denominators 7 and 11, which is 77.
Then, we can multiply each fraction by the appropriate form of 1 so that the denominators are equal to 77.
Here are the steps:
5/7 = (5/7) x (11/11) = 55/77 (multiply the numerator and denominator of the first fraction by 11)
8/11 = (8/11) x (7/7) = 56/77 (multiply the numerator and denominator of the second fraction by 7)
Therefore, 55/77 and 56/77 are the required fractions.

A US nickel has a mass of 5.00 g a US penny has a mass of 2.50 g what is the mass in kilograms of the coins in the
bag contending 186 nickels in 72 pennys
Answer:
1110 g
Step-by-step explanation:
Here is the fastest way to solve this problem: (5 x 186) + (2.5 x 72)
However, if you want a step-by-step explanation, here it is:
The total mass of the coins in the bag is the mass of the nickels plus the mass of the pennies.
Let's start by finding the mass of the nickels in the bag.
We know that one nickel has a mass of 5 g, and that there are 186 nickels. So, the total mass of all the nickels in the bag will be 186 x 5 = 930 g.
Now, let's find the mass of the pennies in the bag.
We know that one penny has a mass of 2.5 g, and that there are 72 pennies in the bag. So, the total mass of all the pennies in the bag will be 2.5 x 72 = 180.
We now add these two masses (930 + 180) to get our final answer, 1110 g.
