Select the three ratios that represent the numbers of blue marbles to red marbles, there are 6 blue marbles and 9 red marbles
Answer:
6:9 or (2:3)
Step-by-step explanation:
A ratio is a term that gives comparison of values. It helps to determine
how much of a particular thing that is compare to other thing.
Given:
numbers of blue marbles= 6
numbers of red marbles= 9
Hence, ratios that represent the numbers of blue marbles to red = 6:9
We can reduce it using factor of 3, hence the ratio becomes(2:3)

Answer:
Acute angle, doesn't have a 90 degree angle to be a right triangle, neither a wide angle to be an obtuse triangle.
I took a pic, I hope that's fine
Answer:
Well in order to find the y-intercept, the “x” has to be 0. To find that we need to find the pattern and to ind the pattern you would need to find the slope. The slope is -4 or 4/ -1
So the Y is 4 and the X is -1
So use that to add or subtract for the pattern
1, -4
0, 0
The y- Intercept is 0 or option (A)

Compare and contrast pyramids and cones.
Be sure to use mathematical terms to describe parts of the solids.
a. In what ways are they alike?
b. In what ways are they different?
Choose either pyramids or cones, and explain how the formula for their volume can be described using other solids.
Answer:
Similarities: both have a base which extends into a single vertex.
Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).
the base of a pyramid is a polygon - the base of a cone is a curve
(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).
Step-by-step explanation:
brainliest?
The key difference between Pyramids and cones are:
A pyramid is basically a code that has a base in the form of a polygon.
Pyramids and cones are alike in the following ways:
Because a cone can be made from a right angle triangle, their formulas are also alike in some ways. Notice that both formulas are related to the height of the object.
The formula for the area of a right angle triangle is:
A = hb/2
The area of a cone is given as:
A = [tex]\pi[/tex] r (r + [tex]\sqrt{(h²+r²)}[/tex]

Naomi's bill for breakfast at a restaurant was $82.She left a15% tip.What was the amount of the tip?
Answer:
$12.30 is the tip
Answer:
$12.30 is the answer.
Step-by-step explanation:
82 * 0.15 = 12.3
What is the measure of ∠A, the exterior angle of the triangle shown below?
F. m∠A = 92°, because 180 – (50 + 38) = 92.
G. m∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.m∠A=78°,because 50–38=12and90–12=78.
J. m∠A = 88°, because 50 + 38 = 88.
Answer: A is 88
Step-by-step explanation: Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88

Find the nth term for each sequence
5,9,13,17,21
1,8,15,22,29
10,6,2,-2,-6
Please help
Answer:
A) -p + 38
B) k + 1
C) a_n = 4n + 1
D) a_n = 7n - 6
E) a_n = 14 - 4n
Step-by-step explanation:
A) 5(p + 6) - 2(3p + 4)
Multiply out the bracket to get;
5p + 30 - 6p + 8
>> -p + 38
B) 7(k - 2) - 3(2k - 5)
Multiply out the bracket to get;
>> 7k - 14 - 6k + 15
>> k + 1
C) Sequence is;
5, 9, 13, 17, 21
This is clearly an AP(arithmetic progression) because the difference between each term is 4.
Formula for nth term of an AP is;
a + (n - 1)d
Where d is difference and a is first term
Thus;
a_n = 5 + (n - 1)4
a_n = 5 + 4n - 4
a_n = 4n + 1
D) Sequence is 1, 8, 15, 22, 29.
This is also an AP.
Difference is 7.
Thus,nth term is;
a_n = 1 + (n - 1)7
a_n = 1 + 7n - 7
a_n = 7n - 6
E) 10, 6, 2, -2, -6
This is also an AP.
Difference is -4
Thus,
a_n = 10 + (n - 1)(-4)
a_n = 10 - 4n + 4
a_n = 14 - 4n
Identify all integers less than -14.

Step-by-step explanation Cause -14 is more closer to 0 then all 4 of those negative numbers so that mean all 4 of these negative numbers are greater than -14 :) if that makes sense
Marco got 15 questions wrong on his 30-question test. What is his grade as a percent?
Answer:
15
Step-by-step explanation:
The grade percentage of Marco is 50%.
What is percentage?A percent is a dimensionless number, meaning that it has no units of measurement, since it represents a part of whatever whole is being measured.
Given that, Marco got 15 questions wrong on his 30-question test.
We need to find his grade as a percent,
So,
Since he got 15 answers wrong,
Therefore, his correct answers = 30-15.
That mean his grade in marks = 15
Now, his grade in percent = 15/30 x 100 = 50%
Hence the grade percentage of Marco is 50%.

5 divided by 14?
......................................
Answer:
0.3571
Step-by-step explanation:
Step 1: Start by setting it up with the divisor 14 on the left side and the dividend 5 on the right side like this:
14[tex]\sqrt{x}[/tex]5
Step 2: The divisor (14) goes into the first digit of the dividend (5), 0 times(s).
Therefore, put 0 on top:
14[tex]\sqrt{x}[/tex]0 5
Step 3: Multiply the divisor by the result in the previous step (14 x 0 =0) and write that answer below the dividend.
14 0
[tex]\sqrt{x}[/tex]5
0
Step 4: Subtract the result in the previous step from the first digit of the dividend (5-0 = 5) and write the answer below.
14 0
[tex]\sqrt{x}[/tex] 5

Ice cream cones cost $1.10 and sundaes cost $2.35. One day, the receipts for a total of 172 cones and sundaes were $294.20. How many cones were sold.
Answer:88
Step-by-step explanation:
1.10c+2.35s=294.20
C+S=172
1.10c+2.35s=294.20 if you multiply by 100.
110c+235s=29420
-110 (cones + sundaes =172)
-110c-110s=-18920
125s/125=10500/125
S= 84
C+84=172
-84. -84
C= 88

Answer:
<ABT = 43°<TBC = 43°Step-by-step explanation:
Given,
Line BT is the bisector of <ABC
So,
3x + 13 = 5x - 7
=> 13 + 7 = 5x - 3x
=> 20 = 2x
[tex] = > x = \frac{20}{2} [/tex]
=> x = 10
As,
We got the value of x = 10
Therefore,
<ABT = 3x + 13 °
= 3×10 + 13 °
= 30 + 13°
= 43°
<TBC = 5x - 7°
= 5 × 10 - 7°
= 50 - 7°
= 43°
Hence,
Value of <ABT = 43° and value of <TBC = 43° (Ans)
