Find the value of x. 120
Answer:
x = 25
Step-by-step explanation:
2x + 70 = 120 {Subtract 70 from both sides}
2x = 120 -70
2x = 50 {divide both sides by 2}
x = 50/2
x = 25

The radius of a cylindrical gift box is (3x+1) inches. The height of the gift box is twice the radius. What is the surface area of the cylinder? Write your answer as a polynomial in standard form.
Answer:
56πx² + 36πx + 6π square inches
Step-by-step explanation:
The radius of a cylindrical gift box is (3x+1) inches. The height of the gift box is twice the radius. What is the surface area of the cylinder? Write your answer as a polynomial in standard form.
The surface area of a cylinder is given as:
2πr(r + h)
The radius of a cylindrical gift box is (3x+1) inches.
The height of the gift box is twice the radius = 2(3x + 1) inches
= 6x + 2 inches
The surface area of the cylinder is:
= 2 × π × 3x + 1( 3x + 1 + 6x + 2) square inches
= 2 × π × 3x + 1(9x + 3) square inches
= 2π × 3x + 1(9x + 3) square inches
= 6πx + 2π( 9x + 3) square inches
= 6πx (9x + 3) + 2π( 9x + 3) square inches
= 56πx² + 18πx + 18πx + 6π square inches
= 56πx² + 36πx + 6π square inches
The surface area of the cylinder is 56πx² + 36πx + 6π square inches

If each quadrilateral below is a trapezoid, find the missing measures.
#1
Answer:
C = 101
E = 46
Step-by-step explanation:
79 + 134 = 213
180 - 79 = 101 (C+F has to equal 180)
79 + 134 + 101 = 314
360 - 314 = 49 (trapezoids have a total degree of 360)
The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.
It is given in the picture that measures the angles of a trapezoid.
It is required to find the other angles.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.
We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°
We know in trapezoid:
∠C+∠F = 180° and
∠D+∠E = 180°
For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°
For ∠E = 180° - ∠E ⇒ 180° - 134° ⇒46°
We have another trapezoid JKLM in which ∠K = 83°
We know in isosceles trpezoid:
∠K = ∠J = 83° and
∠L = ∠M
∠L = 180° - ∠K ⇒ 180° - 83° ⇒ 97° ⇒ ∠M
Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

RESEARCH STUDY 11.2: Dr. Bloedorn is a health psychologist who researches nutrition. She is curious as to whether a new drink additive will help people consume fewer calories during a meal. The drink additive is a white, odorless, tasteless powder that a person can add to any drink. She collects a random sample of 63 overweight students on campus and measures the calories they eat during lunch using a bomb calorimeter. She then gives this additive to the same 63 participants to use at dinner and measures how many calories they eat (again using the bomb calorimeter). Imagine that Dr. Bloedorn finds no difference between the calories consumed with the drink additive and without. This is known as
Answer:
This is known as null effect
Step-by-step explanation:
A null effect is the outcome of an experiment that does not give the effect or result expected. Although an experiment with a null effect has a result, however the result of the experiment does not support the hypothesis
An example of a null result that remains importantly useful is the Michelson-Morley experiment from that partly made possible the formulation of special relativity theory
Find the value of x.
Answer:
x= 128*
Step-by-step explanation:
180*-52*=128*
Answer:
x = 128
Step-by-step explanation:
well we know that for a polygon, the interior angles always add up to 360.
One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128
Math help please answer question a and b ( show work please)
Answer:
a) 24 degrees
b) 50 degrees
Step-by-step explanation:
part a : use sine-1
sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]
sine-1 = [tex]\frac{17}{42}[/tex]
sine-1 = 0.405
missing angle = 23.89
round to the nearest degree = 23.89 = 24
part b : use cosine-1
cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]
cos-1 = [tex]\frac{16}{25}[/tex]
cos-1 = 0.64
missing angle = 50.208
round to the nearest degree = 50.208 = 50

Answer:
14.9 dollars
Step-by-step explanation:
1. There are 30 students and if everyone pay the same, it will be 14.9 dollar. Because the total is 447 dolar and if everyone pay equally, then everyone have the same amount. So, 447 dollar divided to 30 student equal 14.9 per student.
2. The essential information is the total cost of money and the amount of student.
3. 30m = 447
/30 /30
m= 14.9 dollar
4. 14.9*30 = 447

James ran 4 laps and walked 2 laps When running his average speed was 2.5 minutes per lap When walking his average speed was 4.9 minutes per lap How long did it take James to complete 6 laps? 7.4 minutes 9.9 minutes 14.8 minutes Or 19.8 minutes
Answer:
19.8 minutes
Step-by-step explanation:
Total time the 4 laps was completed = 4 x 2.5 = 10 minutes
Total time the 2 laps was completed = 2 x 4.9 = 9.8 minutes
total time = 10 minutes + 9.8 minutes = 19.8 minutes

can someone please help I need it right now!!
Answer:
y=9x
Step-by-step explanation:
First let's find the slope of this.
To find the slop we can take two points.
(1,9) & (3,27)
27-9/ 3-1 (slope equation) = 18/2=9
The slope of the equation is 9.
Now let's use point-slope form to find the equation.
(1,9)
y-9=m(x-1) (substitute the x2 and y2 values for the coordinate values)
y-9=9(x-1) (substitute m for the slope)
y=9x-9+9
y=9x
State the domain, the range, and the intervals on which function is increasing, decreasing, or constant in interval notation
Answer:
Domain: [tex][-1,\infty)[/tex]
Range: [tex](-\infty, 3][/tex]
Decreases over: [tex](-1,-\infty)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = -\sqrt{x + 1} + 3[/tex] --- Missing from the question
Solving (a): The domain
To get the domain, the expression under the square root must not be negative.
In other words:
[tex]x + 1 \ge 0[/tex]
Solve for x
[tex]x + 1 -1\ge 0-1[/tex]
[tex]x \ge -1[/tex]
Hence, the domain is:
[tex][-1,\infty)[/tex]
To get the range, we plot the values of the domain in the expression.
[tex]x = -1[/tex]
[tex]f(x) = -\sqrt{x + 1} + 3[/tex]
[tex]f(-1) = -\sqrt{-1+1} +3[/tex]
[tex]f(-1) = -\sqrt{0} +3[/tex]
[tex]f(-1) = -0 +3[/tex]
[tex]f(-1) = 3[/tex]
[tex]x = \infty[/tex]
[tex]f(\infty) = -\sqrt{\infty +1}+3[/tex]
[tex]f(\infty) = -\sqrt{\infty}+3[/tex]
[tex]f(\infty) = -\infty+3[/tex]
[tex]f(\infty) = -\infty[/tex]
So, the range is: [tex](-\infty, 3][/tex]
To get the interval where the function increases or not, we simply plot the graph of f(x).
See attachment for graph.
From the attachment, it will be observed that the graph of f(x) continuously decreases from x = -1, and it never increased.
This implies that, the graph decreases over the interval [tex](-1,-\infty)[/tex]

Step-by-step explanation:
To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.
Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.
The radius is half of the diameter. So for number 8, the answer would be 2.
hope this helps and that it wasn't to confusing :)
