The measure of ABD is (0.18x + 67) degrees and the measure of CBD is (0.07 + 48) degrees. Find the value of X
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]ABD = 0.18x +67[/tex]
[tex]CBD = 0.07x + 48[/tex]
Required
Find x
The question is incomplete as the relationship between ABD and CBD is not stated.
Assume ABD = CBD
The solution is:
[tex]0.18x + 67 = 0.07x + 48[/tex]
Collect like terms
[tex]0.18x - 0.07x= - 67 + 48[/tex]
[tex]0.11x= -19[/tex]
Solve for x
[tex]x = -\frac{19}{0.11}[/tex]
[tex]x = -172.72[/tex]
Assume ABD and CBD are supplementary
The solution is:
[tex]ABD + CBD=180[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 180[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 180[/tex]
[tex]0.25x = 65[/tex]
Solve for x
[tex]x = \frac{65}{0.25}[/tex]
[tex]x = 260[/tex]
Assume ABD and CBD are complementary
The solution is:
[tex]ABD + CBD=90[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 90[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 90[/tex]
[tex]0.25x = -25[/tex]
Solve for x
[tex]x = \frac{-25}{0.25}[/tex]
[tex]x = -100[/tex]

Two six-sided number cubes are rolled at the same time. What is the probability that the result will have at least one two in it?
(A)7/36
(B)1/5
(C)11/36
(D)1/6
Answer:
1/6
Step-by-step explanation:
There are 12 numbers in total. There is a 2 on each cube so there are two possible chance. 2/12=1/6 2/2=1 and 12/2=6 therefore 2/12=1/6
The solution is, the probability that the result will have at least one two in it is, 1/6.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Two six-sided number cubes are rolled at the same time.
so, we get,
There are 12 numbers in total.
There is a 2 on each cube so there are two possible chance.
2/12=1/6
2/2=1
and 12/2=6
now, we have,
therefore 2/12=1/6.
Hence, The solution is, the probability that the result will have at least one two in it is, 1/6.

On parallelogram ABCD, if A(3,-4) B(10,-2) C(8,-9) and D(1,-11), what are the coordinates of E?
Answer:
(5.5 , - 6.5)
Step-by-step explanation:
Diagonals of a parallelogram bisect each other.
E (x , y) : midpoint of segment AC or segment BD
x = (3 + 8) / 2 = 11/2 = 5.5
y = (-4 + -9) /2 = -13/2 = - 6.5
Answer:
E(5.5,-6.5)
Step-by-step explanation:
We simply draw the parallelogram in coordinate system and read the coordinates of E.
Hosting a breakfast brunch for 25 people, you plan to serve scrambled eggs. The grocery sells eggs in cartons, and each carton can feed four people. How many cartons of eggs must you buy to ensure each guest a serving? A. 4c = 25 B. 25c > 4 C. 4c < 25 D. 25 _> 4c E. 4c _> 25
Answer:
75
Step-by-step explanation:
First, a cartoon of eggs has 12 eggs so if a carton feeds 4 people each person gets 3. Multiply 3x25 to see how many cartons you will need.

1) The product of two numbers is 8. One of the numbers is x. Write an expression for the other number.
2) Fiifi is 3 years older than JoJo. If JoJo is x years old, write an expression for the sum of their ages.
Answer:
1 ) y = 8 / x
2 ) 3 + 2x
Step-by-step explanation:
1 )
One number = x
Let the other number be y.
The product of two numbers is 8,
( x ) ( y ) = 8
xy = 8
y = 8 / x
Expression for the other number is,
y = 8 / x
2 )
JoJo = x years old
Fiifi = ( 3 + x ) years old
Expression for the sum of their ages
= 3 + x + x
= 3 + 2x
If 1 serving of stir fry use 3/5 cup of rice how many cups are in 11 servings?
Answer:
11 servings include 11(3/5), or 33/5, or 6 3/5, cups of rice.
Step-by-step explanation:
If 1 serving includes 3/5 cup of rice, then multiplying both numerals here by 11 produces a similar statement for 11 servings:
11 servings include 11(3/5), or 33/5, or 6 3/5, cups of rice.
CAN SOMEONE PLEASE HELP ME
Answer:
38 degrees
Step-by-step explanation:
this is an isosceles triangle, meaning that the base angles are congruent.
the total triangle is equal to 180
so the equation would be: x=180 - (71+71)
evaluate:
x=180-142
x=38 degrees

Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Given:
Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls.
[tex]\dfrac{4}{5}th[/tex] of this amount is blue paint and the rest is white paint.
To find:
The pints of white paint did she use to paint her bedroom walls.
Solution:
We have,
Total paint used = 6.3 pints
Blue paint = [tex]\dfrac{4}{5}th[/tex] of total paint used
= [tex]\dfrac{4}{5}\times 6.3[/tex]
= [tex]5.04[/tex]
White paint = Total paint used - Blue paint
= [tex]6.3-5.04[/tex]
= [tex]1.26[/tex]
Therefore, Sharon uses 1.26 pints of white paint to paint her bedroom walls.
