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)
Answers
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

[tex]0.15 \times 0.3[/tex]
Answers
Explanation:
0.15=x0.3
We move all terms to the left:
0.15-(x0.3)=0
We add all the numbers together, and all the variables
-(+x0.3)+0.15=0
We get rid of parentheses
-x0.3+0.15=0
We move all terms containing x to the left, all other terms to the right
-x0.3=-0.15
x=-0.15/1
x=-0.15

Step-by-step explanation:
Luis plans to purchase some new baseball bats and gloves before spring training begins. Luis wants to buy the same bats and gloves he purchased last spring, but he can’t remember the price of each item. Luis recalls making two purchases last spring, each totaling $135 and both tax exempt. The first purchase was for a glove and three bats. The second purchase was for two gloves and a bat. If the current prices of these items are the same as last spring, how much will Luis pay this spring for three gloves and four bats?
Answers
Answer:
Luis will pay for three gloves and four bats = $ 270
Step-by-step explanation:
Let the bats be represented by b and gloves by g, then according to the given conditions
3b+ g= $135----equation 1
b+ 2g= $135------equation 2
Subtracting equation 2 from eq. 1 gives
3b+ g= $135----equation 1
-b -2g= -$135------equation 2
2b -g = 0 --------- equation3
2b-g= 0
or 2b= g------ equation4
This means price of 2 bats is equal to price of 1 glove.
Putting value of g in eq. 1 from eq. 4
3b+ 2b= $ 135
5b= $135
b= 135/5= 27
Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54
Luis will pay for three gloves and four bats
= 54*3 + 4*27
= 162+ 108
= $ 270

6a+12 = 3
Subtract 12 from each side
6a+12-12 = 3-12
6a = -9
Divide by 6
6a/6 = -9/6
a = -3/2

Find the measure of C for the circle :
Answers
Answer:
x = 72
Step-by-step explanation:
∠DBC is an included angle and arc DB is its corresponding arc
Relationship between an included angle and its corresponding arc: an included angle is equal to one half of its corresponding arc
so
∠DBC = [tex]\frac{1}{2}[/tex] arc DB
we are given that arc DB = 144
so we exchange arc db with 144
∠DBC = [tex]\frac{1}{2} 144[/tex]
[tex]\frac{1}{2} 144=72[/tex]
so we can conclude that ∠DBC (x) = 72

Bananas cost 0.59 per pound. Create an equation that could be used to find the total cost of y of x bananas
Answers
Answer:
y = 0.59x
Step-by-step explanation:
Cost per pound of banana = $0.59
If Number of banana's = x
Total Cost of an item = price per item * number of items
Therefore,
Total cost, y = price per pound of banana * number of bananas
y = 0.59 * x
y = 0.59x
