Which value of x makes the equation 1.25(6x - 20) = 50 true?
A. x = 6
B. X = 12
C. x = 2
D.X = 10​

The area should be 47.5 CM.

Answer:

Step-by-step explanation:

The figure you see here is a trapezoid.

Area = \(\frac{(a + b)h}{2}\) = \(\frac{(6 + 13)(5)}{2}\) = \(\frac{(19)(5)}{2}\) = \(\frac{95}{2}\) = 47.5 cm

840 different numbers can be created selecting 4 of the digits from the number

From the question, we have the following parameters that can be used in our computation:

Number =  8712395

Digits = 4

The count of digits in the number is 7

Using the above as a guide, we have the following:

So, we have

Numbers = 7 * 6 * 5 * 4

Evaluate

Numbers = 840

Hence, 840 numbers can be formed

Note that given the proof of congruence by SAS, the only thing remaining to know is that "2 corresponding sides and the corresponding included angles of both triangles are equal."

The definition of SAS Congruency is as follows:

The SAS postulate states that two sides and the included angle of one triangle are identical to the corresponding two sides and the included angle of another triangle.

As demonstrated in the triangle, the angles mCAD and mACB are congruent. Thus; m∠CAD ≅ m∠ACB

Because m∠CAD and m∠ACB are congruent, AD and BC must also be congruent. Now, because AC is shared by both triangles ABC and ADC, we get two matching equal sides with the included corresponding equal angles.

As a result, the SAS Congruence postulate is proven.

Weight of Omar after 4 weeks is 9.4375 pounds.

The same attribute is expressed using a unit conversion, but in a different unit of measurement.

For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

Weight of Omar at the time of birth = 8 pound 3 ounces

Weight gained by Omar in 4 weeks = 5 × 4 = 20 ounces

New weight of Omar

= (8 lb 3 ounces) + 20 ounces

= 8 lb + 23 oz

As, we know 16 ounces = 1 pound

23 ounces = 1.4375 pound

Now, total weight of Omar after 4 weeks = 8 lb + 23 oz

                                                                  ≈ 8 lb + (1.4375) lb

                                                                   ≈ 9.4375 pounds

Step-by-step explanation:

In a triangle, the angle that is supplementary to one angle is equal to the other two angles' degrees added together.

In this case, angle 4 is supplementary to angle 3, which means that angle 4 is equal to angle 1 + angle 2. We can see that this is the third option.

Answer:

40%

Step-by-step explanation:

x = # of values below x/n * 100

14 = 4/10 * 100

14 = 40

In the data set 10,10,10,12,14,16,16,18,18,18, 40 percentile is 14.

A percentile is a comparison score between a particular score and the scores of the rest of a group

The given data set is

10,10,10,12,14,16,16,18,18,18

ten, ten , ten, twelve, forteen , sixteen, sixteen, Eighteen, Eighteen, Eighteen

The formula to find percentile is given below

Percentile rank of X=# of values below x/n ×100

Percentile rank of 14=4/10×100

Percentile rank of 14=0.4×100

=40%

Hence 40 Percentile is 14 in given data.

The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.

The correct answer choice is option B.

Malcolm's gift card = $50.

Cost Malcolm's car wash per visit = $7

Martha's gift card = $180

Cost Martha's car wash per visit = Difference between gift card balance of first and second visit

= $180 - $160

= $20

How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7

= $13

Therefore, Malcolm's car wash is cheaper than Martha's car wash by $13

Answer:

I think answer is D but it could be wrong not sure

Based on the fact that the sum of the interior angles need to be equal to 180°, the missing angle is 110°

The sum of all the interior angles need to add up to 180° which means that to find the missing angle, you should subtract the known angles from 180°.

The missing angle is:

= Total angle - Known angles

Solving for the missing angle gives:

= 180 - 21 - 49

= 180 - 70

Answer:

Step-by-step explanation:

The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).

In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.

Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

The logarithmic equation will be \(x=\) \(log_{5} 12\).

What is a logarithmic equation?

A logarithmic equation is an equation that contains a variable in the form of a logarithm. Logarithmic equations are used to solve various types of equations and problems that involve exponential growth or decay. Solving a logarithmic equation involves “un-logging” the equation, or reversing the logarithmic operations. The process of un-logging involves using the inverse of the logarithmic operation to solve for the unknown variable. Logarithmic equations are commonly used in fields such as mathematics, engineering, finance, and science.

Given: \(12\) = \(5^{x}\)

According to the Logarithm Property,

\(a=b^{x}\) ⇔ \(log_{b} a=x\)

Here, a = 12 and b = 5

So, we get:

⇒ \(log_{5} 12=x\) ⇔ \(x=\) \(log_{5} 12\)

Therefore, (A) \(x=\) \(log_{5} 12\) is the correct answer.
