Solution:In order to determine the value of x that makes the equation true, we need to subtract 10 from both sides:x+10=18x=18-10x=8Therefore, when x=8, the equation x+10=18 is true.Hope it helps.

ummi and julio each have a bag that contains 2 blue marbles, 2 green marbles and 2 purple marbles. Ummi selects a marble from her bad, replaces it, and then selects another. julio selects a marble from her bag, replaces, it and then selects another. who has a greater probability of selecting 2 marbles of the same color from the bag? explain.
Answer:
None.
Step-by-step explanation:
Let blue, green and purple be B, G, and P respectively.
Sample Space = 2+2+2 = 6
p(B) = p(G) = p(P) = 2/6 = 1/3
Probability that the two marbles Ummi selected are of the same color (note that the marbles were replaced after selection)
B = (1/3)•(1/3)
+
G = (1/3)•(1/3)
+
P = (1/3)•(1/3)
= 3•(1/9) = 1/3
.
The same thing goes for Julio.
They have the same chance/probability of picking two marbles of the same color.

Which pair of triangles are similar?

B
Triangles 3 and 4 each have a 42° angle.
с
Triangle 5 has a 70 angle and a 95° angle. Triangle 6 has a 30° and a 75º.
a
D
Triangle 7 has a 30 angle and a 90°. Triangle 6 has a 30° and a 60°.
Answer:
[tex] \sf \fbox{Option D have pair of triangles are similiar}[/tex]
Step-by-step explanation:
To prove triangles are pair we will use AAA property.
ln option A the given triangles 1 & 2 have a 36° Angle, but the remaining two angles of both the traingle are not mentioned, as long as we don't know the measure of other two angle of both the traingle we can't say that pair of triangles are similar.
Similarly In option B triangles 3 & 4 can't be pair of similar triangle
In option C triangle 5 & 6 don't have any common angle, hence it does not follows AAA property and the given pair of traingles are not similar.
In option D Two angles of each triangle are given so we can easily find the third angle of both the triangle. let's solve for the third angles of triangle 7 and 8.
in triangle 7,
given angles are 30° and 90°let the third angle be X,now,30+90+X = 180(sum of all angles of triangle is 180)X= 180-90-30X= 60All three angles of triangle 7 are 30, 60 & 90
Now in triangle 8,
given angles are 30° and 60°let the third angle be Y,now,30+60+Y = 180(sum of all angles of triangle is 180)Y= 180-90Y= 90All three angles of triangle 8 are 30, 60 & 90
Hence, both the triangles have same measure of all three angles we can say that triangle 7 & 8 are similar triangle.

Answer:
18.8
Step-by-step explanation:
Hey there!
In order to find the solution to this question, we need to find the circumference
To find the circumference, you need to take the diameter and multiply it by 3.14 which is pi
In this case, the diameter is 6
6 x 3.14 is 18.84 so this means that the circumference of the circle, or in this case, a cookie, is 18.84
Also, it says to round to the tenth so our final answer will be 18.8
So the answer to this question is 18.8
C=18.8
Solution:Circumference = C=πdPlug in the value of d:C=π×6C=6π (in terms of pi)C=18.8Hope it helps.

The interest will the CD has earned more than the savings account after 1 year will be $49.90. Then the correct option is B.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Greg invests $2,680 in a CD paying 7.0% interest, and $3,060 in an online savings account paying 4.5% interest.
The amount of the interest on the CD will be
→ 2680 × 0.07 = $187.6
The amount of the interest by the online savings will be
→ 3060 × 0.045 = $137.7
Then the interest will the CD has earned more than the savings account after 1 year will be

A trail around a river is 3 1/4 miles long. What is the length, in feet, of the trail?
Answer: 17160 feet
Step-by-step explanation:
We know that 5280 feet = 1 mile
So all we have to do is multiply 3 1/4 by 5280
Let's split the 3 and 1/4 up to make the multiplication easier
3×5280=15840
[tex]\frac{1}{4}[/tex]×5280=[tex]\frac{5280}{4} =1320[/tex]
Now add them together

how should Kim classify the water?
Using the table at the right, Kim would have to classify the water as gaseous matter in this case.
What are the states of matter?The states of matter are the distinct form in which matter exists. There are 5 states of matter Solids; Liquids; Gaseous; Plasma; and Bose-Einstein condensate.
Kim classify the water as gaseous because she boiled all the liquid away. Hence in their evaporated state, the water now assumes a gaseous form.

Which comparison is true?
A 5,000 pounds < 2 tons
B 6 pounds > 98 ounces
C 36 ounces < 2 pounds
D 4 pounds > 60 ounces
Answer: 4 pounds > 60 ounces (D)
Step-by-step explanation:
Since there are 16 ounces in a pound, you just multiply 16 (ounces) by 4 (pounds). If you evaluate 16*4, you would get 64 ounces, so 64 is greater than 60. So the answer is D.

Jaleesa bought 2 notebooks for $8. 75 each and 1 textbook for $74. 95. If the sales tax was 7%,
what was the total cost of Jaleesa's purchases?
Write the answer as a decimal to 2 places
Answer:
Step-by-step explanation:
First calculate the amount of notebooks and textbook
Cost of 2 notebooks = 2 *8.75
= $ 17.5
Cost of 1 textbook = $ 74.95
Total cost = 17.5 + 74.95
= $ 92.45
Tax = 7% of total cost
= 0.07 * 92.45
= $ 6.47
Total cost = 92.45 +6.47
= $ 98.92
Jaleesa bought 2 notebooks for dollar 8. 75 and 1 textbook for dollar 74.95 . If the sales tax was 7[tex]{\%}[/tex],
what was the total cost of Jaleesa's purchases?
Explanation -;In this question we are provided with the cost of each textbook and notebook and it is given that Jaleesa bought 2 notebook and 1 textbook and the sale tax was.7% and we are asked to calculate the total cost of Jaleesa's purchases
First we will calculate the cost of two notebooks
Rate of 1 notebook = $8.75
Cost of 2 notebook = $(8.75 × 2) = $17.5
Now, we will calculate the total cost
Total cost of 2 notebook and 1 textbook = $(17.5 + 74.95) = $92.45
Sales tax was 7%
7% of $92.45
→ [tex]\dfrac{7}{100}[/tex] × 93.45
→ $6.47
Total cost = $(92.45 + 6.47) = $98.92.
