Answer:

173 + h

Step-by-step explanation:

173 + h

Answer:

31.869 kg.

Step-by-Step Explanation:

Inner radius,r=12/2=6cm

thickness=1cm

so,outer radius,R=6+1=7cm

height,h=1m=100cm

volume=pi×(R^2-r^2)×h

=22/7×(7^2-6^2)×100

=22/7×(49-36)×100

=22/7×13×100

286/7×100

=28600/7

since,density=7.7gm/cm^3

also,weight=volume×density

weight=28600/7×7.7gm

=31460gm

or,31.46 kg

Answer:

2:20 p.m.

Step-by-step explanation:

Let's start with what we know

Tiana starts at 12:30 and spends 55 minutes at archery and 55 minutes sailing.

This question wants us to find what time does sailing end. To find this, we add 12:30 with 55 minutes for archery, then another 55 minutes for sailing

So,

12:30 + 55 minutes = 1:25

Then,

1:25 + 55 minutes = 2:20

So, she will end sailing at 2:20 p.m.

Answer:

cm

Step-by-step explanation:

if using centimeters to determine the perimeter then it's just cm.

If you're using centimeters to determine area it would be cm^2.

If you're using centimeters to determine volume it would be cm^3.

Answer:

She bought 46 highlighters and was given 15 for free

Step-by-step explanation:

Divide 92 by 2, which gives you 46

46 is the number of ens you bought

next Divide 46 by 3 to calculate how many she was given for free

46 ÷ 3 = 15.333

you will round down which gives you 15.

Answer:

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

to find the slope of two points the formula is (y2-y1)/(x2-x1) so if you plug in the numbers given into that formula you get (3-4)/(7-10), then simplifying that you get (-1)/(-3) and the negatives cancle out so you get 1/3

The slope is the inclination of a line and can be calculated by the ratio of the difference of y's coordinate to x's coordinate thus the slope of the line passing through points  (10,4)and (7,3) is 1/3.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines . The slope could be positive or negative.

The slope of the lines passing through points  (x₁, y₁) and (x₂, y₂) is,

⇒ (y₂ - y₁)/(x₂ - x₁)

As per the given points  (10,4)and (7,3)

Slope = (3 - 4)/(7 - 10)

Slope = -1/-3 = 1/3

Hence "The slope is the inclination of a line thus the slope of the line passing through points  (10,4)and (7,3) is 1/3".

Answer:

x is (-infinite, -12) and (-6, infinite)

Step-by-step explanation:

Meaning that x is less than -12 and greater than 6. I think...

Applying the inscribed angle theorem, we have:

1. m∠ABC = 79°

2. x = 10

The inscribed angle theorem states that the measure of an inscribed angle = 1/2(measure of intercepted arc).

Thus:

1. Find m∠ABC:

m∠ABC = 1/2(measure of arc AC) [inscribed angle theorem]

Substitute

m∠ABC = 1/2(360 - 94 - 108)

m∠ABC = 79°

2. Find the value of x:

m∠DEF = 1/2(DF) [inscribed angle theorem]

Substitute

51 = 1/2(14x - 38)

2(51) = 14x - 38

102 = 14x - 38

102 + 38 = 14x

140 = 14x

10 = x

x = 10

The percentage of these test scores that are less than 81 will be 60%.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The quantity of anything is stated as though it were a fraction of a hundred.

A fraction of 100 can be used to express the ratio.

Values less than 81 =  (59, 57, 75, 57, 65, 77),n=6

Total no of values, N=10

Percentage = n/N×100

=6/10×100

=60%

Hence, the percentage of these test scores that are less than 81 will be 60%.

Answer:

520 - 303.93 - (10.99 * 4) - 25.25 - 73.43x ≥ 0

-

1) Parentheses

520 - 303.93 - 43.96 - 25.25 - 73.43x ≥ 0

-

2) Combine like terms

146.86 - 73.43x ≥ 0

-

3) Get the variable term alone

-73.43x ≥ -146.86

-

4) Divide to solve

x ≤ 2

** dividing by a negative number, the inequality sign flips **

ANSWER :

x ≤ 2

Step-by-step explanation:

303.93+(4×10.99 )+25.25+73.43x = 520

303.93 + 43.96 + 25.25 + 73.43x = 520

373.14 + 73.43x = 520

73.43x = 520 - 373.14

73.43x = 146.76

x = 146.76 ÷ 73.43

Step-by-step explanation:

I got 63% wrong :') it showed that 97% was right.

The percent increase between the total without and the total with Tristi's employer's contribution is 97% option (D) is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that;

Tristi contributes a set percentage of her gross pay to a 401k account and will have a total of $133,473.00 by retirement.

Using the formula of percentage increase:

= [($262,612.00 - $133,473.00)/ $133,473.00] x 100

= 97 %

Thus, the percent increase between the total without and the total with Tristi's employer's contribution is 97% option (D) is correct.
