In circle A shown below, BD is a diameter and the measure of CB is 36°:
What is the measure of angle DBC? (4 Points)
Answer:
54degrees
Step-by-step explanation:
Find the diagram attached
Since the angle of the triangle in a semicircle is a right angle, hence <DCB = 90 degrees
Given
<DBC= 36 degrees
Required
<DBC
Since the sum of angles in the triangle DBC is 180 degrees, hence;
<DBC+<DBC+<DCB = 180
<DBC+36+90 = 180
<DBC + 126 = 180
<DBC = 180 - 126
<DBC = 54degrees
Hence the measure of angle DBC is 54degrees
Use 5 miles = 8 km to convert 18 mph to m/s.
Give your answer as an integer.
Answer:
8 m/s.
Step-by-step explanation:
18 miles = 18*8/5 = 28.8km
28.8 km = 28.8 * 1000
= 28,800 m.
There are 3600 seconds in an hour.
Therefore:
28800 meters per hour = 28800/3600
= 8 m/s.

8a - 3 = 5(a + 7) + 3a
Answer: NO SOLUTIONS
Step-by-step explanation:
8a-3=5a+35+3a
8a-3=8a+35
-8a -8a
-3 does not equal to 35
NO SOLUTIONS
Answer: 8a=38+8a²
Step-by-step explanation:
8a-3=5(a+7)+3a
8a-3=5a+35+3a
8a-3=8a²+35
8a=35+3+8a² (I moved 3 to put it with 35 because they are the same, I couldn't do the same for 8a and 8a² because of the 2)
8a=38+8a²

Jasmine bought a new stereo system for $480.50 if the tax rate is 6 1/2 what was the total cost of the stereo system?
Answer:
$511.7
Step-by-step explanation:
Given data
Cost of stereo system= $480.50
Tax= 6 1/2% = 6.5%
Let us find the amount of the tax
=6.5/100*480.5
=0.065*480.5
=$31.2
Hence the amount of the tax = $31.2
Therefore the total cost is
=31.2+480.50
=$511.7

Graph y = x2 - 8x + 13
Answer:
Step-by-step explanation:
From the given x^2 - 8x + 13 we can find several points to graph to represent this quadratic function.
The y-intercept is (0, 13) and stems from letting x = 0.
b
The axis of symmetry is x = - -----
2a
-8
Since a = 1 and b = -8, the axis of symmetry is x = - ------- = 4
2(1)
and so the vertex is at (4, 4^2 - 8(4) + 13), or (4, -3)
If you want to go the extra mile, find the roots of the given equation. These are also your x-intercepts. One such intercept is (2. 0).
Plot these points and draw a smooth curve through them.

It takes 3/4 of a cup of sugar to make one batch of cookies how many cups of sugar does he need to double the recipe
Answer:
Step-by-step explanation:
3/4 cups → 1 batch
x cups → 2 batches
x = 2(3/4) = 6/4 = 1 1/2 cups
3/4 cups → 1 batch
y cups → 9 batches
y = 9(3/4) = 6 3/4 cups
Anna has a jewelry box that is 10 inches long, 8 inches wide, and 3 inches high. What is the volume of her jewelry box?
No sites-No Free Point's-
Answer:
The box volume is 240 in^3
Step-by-step explanation:
The volume of a rectangular box is V = L*W*H.
Here, that would be V = (10 in)(8 in)(3 in)= 240 in^3
Answer:
Volume is 240 inches
Step-by-step explanation:
Volume = Length x Width x Height
L W H V
10 x 8 x 3 = 240 inches
Quintaveous’s father gave him a baseball card collection for his birthday. He told
Quintaveous that its current value is $250 and that each year the value will grow at
a rate of 10%. What is the approximate value of the card after 6 years?
Group of answer choices
$310
$500
$133
$443
Answer:
the approximate value after 6 years is $443
Step-by-step explanation:
The computation of the approximate value after 6 years is shown below:
= Current value × (1 + rate of interest)^number of years
= $250 × (1 + 0.10)^6
= $250 × 1.1^6
= $442.8903
= $443
Hence, the approximate value after 6 years is $443
Therefore the last option is correct
Kaitlyn makes 65% of her free throws on the basketball court. If she attempts 50 free throws in practice, about how many would you expect her to make?
Answer: Its 33 !
Step-by-step explanation:
Okay so its actually not that bad at all !
So STEP 1
Convert your percent into a decimal : 65% --> .65
STEP 2 you still following me you got this !
since kaitlyn attempts to throw 50 free throws all you need to do is multiply your decimal you converted by 50
it would look like this .65 X 50 = 32.5
Step 3
Depending on what your answer choices are 32.5 is going to have to be rounded upwards remember anything at or above 5 you round up. Anything below 5 you round down so your answer will be 33 in this problem
Summary
when seeing questions like this convert that percent into a decimal then depending on what is being counted for. you multiply your decimal by the number ! Hope this helps thanks for reading <3

Jessica is planting a garden. It has the shape of a right triangle. She wants 4 plants for each square yard of area. How many plants does she want in the garden?
A right triangle has a base of length 9 yards and a height of 12 yards. The longest side has length 15 yards
Answer:
216 plants
Step-by-step explanation:
To answer this question :
Determine the area of a triangle Multiply the area of the triangle by the number of plants per square yardArea of a triangle = 1/2 x base x height
1/2 x 9 x 12 = 54 yards²
54 x 4 = 216 plants

Find the value of X in this hexagon
Answer:
x = 130°
Step-by-step explanation:
number of sides = 6
the sum of the total interior angles = (6 x 180) - 360 = 720°
x = 720 - 125 - 120 - 100 - 120 - 125 = 130°
PLEASE HELP I WILL MARK BRAINLIEST!!
Answer:
79 degrees.
Step-by-step explanation:
There are 7 total temperatures, 68, 82, 81, 82, 74, 75, and 91 degrees. To find the mean, we add all of the temperatures together and divide it by the number of tempuratures-- 7.
68+82+81+82+74+75+91 = 553.
553 / 7 = 79.

Triangle XYZ is inscribed in semicircle O shown below such that YZ = 7 and YX = 10. Which of the following
is closest to the radius of the semicircle?
(1) 5.8
(2) 6.1
(3) 11.6
(4) 12.2
Answer:
(2) 6.1
tep-by-step explanation:
∠Y is a right angle, so ΔXYZ is a right triangle
[tex]XZ^{2} = XY^{2} + YZ^{2}[/tex]
[tex]XZ^{2} = 7^{2} + 10^{2}[/tex] = 49 + 100 = 149
XZ = [tex]\sqrt{149}[/tex] = 12.2
XZ is the diameter of the semicircle, therefore, the radius is 12.2/2 = 6.1
You roll a 6-sided die.
What is P(5)?
Answer:
1/6
Step-by-step explanation:
you have a 6 sided die that is numbered 1, 2, 3, 4, 5, and 6.
you roll it once, so the probability that you will roll a five is 1/6
this is because you only want one specific number so that goes on the numerator of the fraction.
then, you have to multiply how many sides you have on the die to the number of rolls. in this case we have one roll and six sides. so the six goes on the denomerator side of the fraction
PLEASE HELP !!!!!!! what is the coordinate of the vertex of the following parabola: (x-1)^2=12(y+2)
a. (-1, 2)
b. (1, 2)
c. (1, -2)
d. (0, 12)
The coordinate of the vertex of the parabola is option (C) (1,-2) is the correct answer.
What is the equation of the parabola?The set of all points in a plane that are equidistant from a fixed line and a fixed point (not on the fixed line) in the plane is a parabola. The fixed line is the ‘directrix’ and the fixed point is the ‘focus’. The point of intersection of the parabola with the axis is the vertex.
For the given situation,
The equation of parabola is [tex](x-1)^2=12(y+2)[/tex] ------ (1)
The diagram below shows the parabola and the vertex of the equation of parabola.
The general form of the equation of parabola is
[tex](x-h)^{2} =4a(y-k)[/tex]
Here the vertex is (h,k)
Now compare the equation 1 with this general form, we get
⇒ [tex]h=1[/tex] and [tex]k=-2[/tex]
Hence we can conclude that the coordinate of the vertex of the parabola is option (C) (1,-2) is the correct answer.
