Answer:

1: c

2: 114

Step-by-step explanation:

Answer:

Part 1 is C

Part 2 is B

Step-by-step explanation:

Part 1: First convert 35% into a decimal (.35)

Then convert it into a fraction ([tex]\frac{7}{20}[/tex])

Now convert 10% into a fraction (.10)

Convert into a fraction ([tex]\frac{1}{10}[/tex] or [tex]\frac{2}{20}[/tex])

Part 2: Convert 15% into a decimal (.15)

Multiply .15 by 760 (114)

[tex]\sf 100x^2 + 180x+81\\\\= (10x)^2 + 2(10x)(9)+ (9)^2\\\\Using \ Formula \ a^2 +2ab+b^2 = (a+b)^2\\\\= (10x+9)^2\\\\\rule[225]{225}{2}[/tex]

Hope this helped!

Answer:

[tex](10x + 9 {)}^{2} [/tex]

Step-by-step explanation:

1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.

[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]

2) Use square sum: ( a + b )² = a² + 2ab + b².

[tex](10x + 9 {)}^{2} [/tex]

Hence, the answer is (10x + 9)².

Answer:

The total value of the liquid in the container is about $41,866,666.67.

Step-by-step explanation:

A spherical container has a diameter of 100 centimeters.

It is filled with a liquid that costs $80 per cubic centimeter.

And we want to determine the total value of the liquid in the container.

We can start by finding the volume of the container.

Since the container has a diameter of 100 centimeters, its radius if 50 centimeters.

The volume of a sphere is given by:

[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]

Substitute. We will also use 3.14 for π. So:

[tex]\displaystyle =\frac{4}{3}(3.14)(50)^3=523333.33...\text{ cm}^3[/tex]

(Try not to round intermediate values.)

Since each cubic centimeter costs $80, we will multiply the total volume by the cost per cubic centimeter to find the total value. Thus, the total value is:

[tex](523333.\overline{3})(80)\approx \$41, 866, 666.67[/tex]

The total value of the liquid in the container is about $41,866,666.67.

Answer:

-9

Step-by-step explanation:

(x + 89)° + (x + 109)° = 180°

(interior angles on the same side of transversal)

(2x + 198)° = 180°

2x + 198 = 180

2x = 180 - 198

2x = - 18

x = - 18/2

x = - 9

Answer:

Actually, 20 divided by 2 1/3 equals 8.57 repeating (8.571428...), which can be rounded to 8.57 to two decimal places.

To see why, we can convert the mixed number 2 1/3 to an improper fraction:

2 1/3 = (2 * 3 + 1) / 3 = 7/3

Then, we can rewrite the division as a fraction and simplify:

20 / (7/3) = 20 * (3/7) = 60/7 = 8.571428...

So, 20 divided by 2 1/3 is approximately 8.57.

Answer:

61°

Step-by-step explanation:

In order for triangle LMN and PQR to be congruent, angle M and angle Q must equal. thus, we can set 2x-26=x+16

with basic algebraic manipulation, x=42. we then plug it back into the angle M or Q, getting angle M/Q= 58°

since this is a isoceles, the 2 base angle are identical, so 180= 58+2(angle P)

thus, angle P= 61

Answer:

x=10

Step-by-step explanation:

Mean (Average) 62.333333333333

Median 60

oWhat can I say execpt your welcome

The mean is greater than the median.

Option (B) is correct.

To find the statements is true.

A branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data.

Half the students scored 55.

The next highest score is 60. So the median is (55+60) / 2 = 57.5.

A few students scored 72, so the mean is slightly greater than the mean of 55 and 60.

Therefore, the mean is greater than the median.
