one angle= 10°
to find:the remaining 3 angles.
solution:angle sum= 360°
2x10=20
360–20=340
340/2=170
so, the remaining 3 angles are 10, 170 and 170.
Answer:
10, 170, 170
Step-by-step explanation:
Opposite angles of parallelogram are equal
Consecutive angles in a parallelogram are supplementary (add 180°)
Interior angles in a quadrilateral add up to 360°.
10+10=20 (2 opposite angles of 10 each)
360-20= 340
340/2 = 170 (2 opposite angles of 170)
10+170 = 180 (2 consecitive angles supplementary)
10+10+170+170=360

Please help im new here! a library would like to see how many of its patrons would be interested in regularly checking out books from an enlarged print section. they randomly surveyed 200 patrons and 6 patrons responded that they would regularly check out books from an enlarged print section. if the library has a total of 3200 patrons, how many people can they expect to regularly check out books from an enlarged print section?
Answer:
96 people are expected
Step-by-step explanation:
Hello!
We can first convert the surveyed group results into a percentage.
So 3% of the sampled survey were interesetd. To find the actual expected number of patrons, we find 3% of 3200.
3% of 32000.03 * 32009696 people are expected.

What is the volume of plane shapes?The volume of a flat shape resembles a three-dimensional representation of the shape's boundary.
Given:
The figure can be differentiated into two shapes;
A rectangleA triangleThe volume of the rectangle is known as:
= Length × Breadth
= 7 inches × 5 inches
= 35 inches²
The volume of the triangle is:
= 1/2 × base × height
= 1/2 × 2 × 5
= 5 inches²
The total volume of the base of the fish tank now is:
= 35 inches² + 5 inches²
= 40 inches²
Now, the volume of the fish tank is:
= Height × base of the fish tank
= 6 inches × 40 inches²
= 240 in³

Evaluate the function it at x = -1 and x = 5.
P(x)=
x²+2 if x <4
2x+10 if x >4
Answer:
f(-1) = 3
f(5) = 20
Step-by-step explanation:
When evaluating a piecewise-defined function, the first step is to locate the argument value in the correct domain. Then the corresponding function is evaluated in the usual way.
__
For x=-1, the relevant piece is the one defined for x < 4:
f(x) = x² +2
f(-1) = (-1)² +2 = 3
__
For x=5, the relevant piece is the one defined for x > 4:
f(x) = 2x +10
f(5) = 2(5) +10 = 20
_____
Additional comment
The function written in this problem statement is "undefined" at x=4, so the graph would ordinarily show a "hole" there. We're not sure whether that is intentional.
Solve the equation in degrees for all exact solutions where appropriate. Round approximate answers in degrees to the nearest tenth. Write answers using the least possible nonnegative angle measures.
The equation is an illustration of trigonometry ratios, and the non-negative values of x are 30 and 270 degrees
How to solve the equation?The equation is given as:
2sin²(x) + sin(x) = 1
Let y = sin(x)
So, the equation becomes
2y² + y = 1
Rewrite as:
2y² + y - 1 = 0
Expand
2y² + 2y - y - 1 = 0
Factorize
2y(y + 1) - 1(y + 1) = 0
Expand
(2y - 1)(y + 1) = 0
Split
2y - 1 = 0 or y + 1 = 0
Solve for y
y = 0.5 or y = -1
Recall that: y = sin(x)
So, we have:
sin(x) = 0.5 and sin(x) = -1
Take the arcsin of both sides
x = sin⁻¹(0.5) and x = sin⁻¹(-1)
x = 30 degrees and x = 270
Hence, the non-negative values of x are 30 and 270 degrees

What is the first step when rewriting y = 6x2 18x 14 in the form y = a(x – h)2 k? 16 must be factored from 18x 14 x must be factored from 6x2 18x 6 must be factored from 6x2 14 6 must be factored from 6x2 18x
The first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k is to factor out 6 from the first two terms
Writing an equation in vertex formThe standard vertx form of an expression is given as y = a(x – h)^2 + k
Given the quadratic expression given as:
y = 6x^2 + 18x+ 14
Before a quadratic equation can be transformed to its vertex form, the coefiicient of x^2 must be 1.
To do that, you will factor out 6 from the first two terms to have:
6(x^2 + 3x) + 14

Step-by-step explanation:
Answer:
308 in³, 101 in³ (from left to right)
Step-by-step explanation:
Volume of cylinder= πr²h, where r is the radius and h is the height.
Cylinder on left
radius= 7 in
height= 2 in
Volume
= π(7²)(2)
= 98π
= 308 in³ (3 s.f.)
Cylinder of right
radius= 4 in
height= 2 in
Volume
= π(4²)(2)
= 32π
= 101 in³ (3 s.f.)
how do i find a,b and k?
Answer:
a = 1
b = 2
k = -2
Step-by-step explanation:
Given:
[tex]\displaystyle \large{y=k(x-a)^2(x-b)}[/tex]
First, find the a-value and b-value by observing the graph. Notice that once the graph hits x = 1, it just goes up or concave up - that indicates to be the double roots of function. Therefore:
Our a-value is 1
Second, find the b-value. Another x-intercept beside double roots x = 1 is x = 2 as shown in the graph. Therefore:
Our b-value is 2
Third, find the k-value. Right now we have the equation:
[tex]\displaystyle \large{y=k(x-1)^2(x-2)}[/tex]
To find the k-value, simply find a point’s value (x,y) to substitute. According to the graph, you can try substitute (0,4) in:
[tex]\displaystyle \large{4=k(0-1)^2(0-2)}\\\displaystyle \large{4=k(-1)^2(-2)}\\\displaystyle \large{4=k(1)(-2)}\\\displaystyle \large{4=-2k}\\\displaystyle \large{k=-2}[/tex]
Therefore, the value of k is -2
