Answer:
80 cc.
Step-by-step explanation:
We work in amounts of salt in the solutions:
0.09x + 0.17*80= 0.13(x+ 80) where x is the required volume of 9% solution.
0.09x + 13.6 = 0.13x + 10.4
13.6 - 10.4 = 0.13x - 0.09x
3.2 = 0.04x
x = 3.2 / 0.04
x = 80

SOLVE FOR X!!
(will mark brainliest)
Answer:
19
Step-by-step explanation:
Since it is a 90° angle we can say that 3x-15+2x+10 = 90.
3x-15+2x+10 = 90
5x-5=90
5x=95
x=19
By solving this we find that x is equal to 19.
Answer:
19
Step-by-step explanation:
3*19 = 57
57 - 15 = 42
2*19 = 38
38 + 10 = 48
48 + 42 = 90
(As this is a 90 degree angle)

The ratio of the interior angles of a triangle is 2 : 3 : 4. What are the angle measures? Write the angle measures from least to greatest.
9514 1404 393
Answer:
40°, 60°, 80°
Step-by-step explanation:
The total of ratio units is 2+3+4 = 9.
The total of angles in a triangle is 180°, so each ratio unit stands for 180°/9 = 20°.
The angle measures are ...
20° × 2 = 40°
20° × 3 = 60°
20° × 4 = 80°
Aaron currently earns $1,400 per month working. Each year he will get a $150 per month raise. How much money will Aaron earn per month in 7 years?
the correct answer is 10290000
Answer:
130,200
Step-by-step explanation:
Earnings for 7yrs= $1,400 × 12 months × 7yrs
= $117,600
Raise for 7 yrs= $150 × 12 months × 7yrs
=$ 12,600
Earnings in 7yrs= $117,600 + $12,600
= 130,200

Answer:
Isosceles right
Step-by-step explanation:
And isosceles triangle has 2 congruent sides, and since 90° is a right angles, it is a right triangle.
Answer:
isosceles acute I believe, since the two even sides are acute angles, however it could also be right since the top angle is a right angle and therefore the other two equal a right angle sorry if this didn't come in very useful

Answer:
1) -3/2
Step-by-step explanation:
The common ratio is the amount you multiply by to get to the next number in the sequence. To calculate this you will need to divide the term by its preceding term.
For example (3/4) / (-1/2)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (3/4) x (-2/1) = -3/2
Check this by doing the next term (-9/8) / (3/4)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (-9/8) x (4/3) = -3/2

Function Modeling
The behavior of some parameters that depend on a set of variables can be modeled in several ways, like linear, quadratic, exponential, logarithmic, among many others.
The selection of the model is often a complex decision that involves statistics and data analysis.
The question provides us with four points where the volume of popcorn bags and the price in dollars. The easiest function that can be used is the line.
The equation of a line of the volume V and the price p can be found with the expression
We'll use the first two values (6,10) (8,20)
Simplifying and rearranging, we get the model
To test the accuracy of the model, we compute the values of p for V=35 and for V=48
Since the computed values are equal to those of the table, the model is accurate. We can now predict the price for V=60
The price for a 60-ounce bag of popcorn would be $16

Answer: 13.7ft (1 decimal place)
Step-by-step explanation:
For this question you will have to use Pythagoras theorem.
The formula for the short side is x²=c²-b² and when you put the numbers from this question into it you get x²=15²-6²
15²=225
6²=36
x²=225-36
x²=189
Then, as you want to find x on its own, you would have to square root 189 which is 13.7 (1 decimal place).
Hope this helps :)
How many angles do 5 triangles and 3 rectangles have?
(1) 7
(2) 17
(3)
18
(4) 27
Answer:
27
Explanation:
5 * 3 = 15 (5 triangles with 3 angles each)
3 * 4 = 12 (3 rectangles with 4 angles each)
15 + 12 = 27
Answer:
the answer is 27 because a triangle has 3 sides so multiply 3 tomes 5 because of how many triandles and then the same with the rectangle that has 4 sides then multiply by 3 because of the number of triangles you have
Mariel says that a jewelry box that is 3 inches high, 4 1/2 inches wide, and 5 inches long has a volume of 67 1/2 inches. Katie says that answer is not quite correct. What is the error in Mariel's answer?
Answer: inside width, length and heights may be smaller
Step-by-step explanation. Walls of box have certain thickness, assume 0.1 inches. Then inner measures would be 2.8 in, 4.3 in and 4.8 in. You need to reduce thickness of wall from both sides.

Which statement is true based on the diagram?
O PQR - STR
O RST ~ RQP
O QR corresponds to TR.
O PR corresponds to RS.
Answer: B
O RST ~ RQP
Step-by-step explanation:
The statement that is true based on the diagram is: "QR corresponds to TR."
Based on the given information, we have the following:
1. PQ = 8 cm
2. QR = 12 cm
3. RT = 18 cm
4. ST = x cm (length not specified)
Now, let's analyze the statements:
1. [tex]\( \triangle PQR \sim \triangle STR\)[/tex] - This statement is not necessarily true because we don't have enough information to determine if the two triangles are similar.
2. [tex]\( \triangle RST \sim \triangle RQP\)[/tex] - This statement is not necessarily true because we don't have enough information to determine if the two triangles are similar.
3. QR corresponds to TR - This statement is true based on the fact that QR and TR are corresponding sides of the triangles [tex]\(\triangle PQR\)[/tex] and [tex]\(\triangle STR\)[/tex] that are intersected by transversal QRST.
4. PR corresponds to RS - This statement is not necessarily true because we don't have enough information to determine if PR and RS are corresponding sides of the triangles [tex]\(\triangle PQR\)[/tex] and [tex]\(\triangle STR\)[/tex].
So, the correct answer is: QR corresponds to TR.

What is ur minecraft usernaem
Answer:
consistent
A consistent and independent solution to a system of linear equations is one point
A consistent and dependent solution to a system of linear equations is where they are the same line ( they could also be called equivalent)
An inconsistent solution is where there is no solution, the lines do not cross
Since the lines cross at exactly one point, this is a consistent and dependent solution
The solution is at x = 3 ( 3 units to the right of the origin)
and y = 2 ( 2 units up from the origin)
