Answer:
Answer to the 1st question is: 16/9 or 16:9 (whichever form you use)
Answer to the 2nd question is: 7/9 or 7:9
Step-by-step explanation:
Key skills needed: Number theory, Ratios, and Fractions
1) Let's look at the first question. A ratio is usually a number of something over a number of another thing. One such example is 5 apples : 4 oranges (or 5 apples/ 4 oranges - whichever form you write in).
Based on that let's look at the first problem. We want to find the ratio of all the marbles in the bag to the blue marbles. So it would be --> the total # of marbles over the number of blue marbles. The total number of marbles is 7+9= 16. This would be our first number, or the numerator. The number of blue marbles is 9. This would be our 2nd number, or the denominator of the ratio.With this information --> The ratio would be 16/9 or 16:92) Now let's look at the 2nd question. The number of red marbles to the number of blue marbles is the ratio we need to find.
The number of red marbles is 7. This would be our first number or the numerator. The number of blue marbles is 9. This would be our second number or the denominator. Therefore, the ratio would be --> 7/9 or 7:9Hope you understood and have a nice day!! :D

In the figure below, ma = 7x + 5 and mb = 28x. The angles are
supplementary
Find the ma
b
a
40 degrees
140 degrees
35 degrees
5 degrees
Step-by-step explanation:
Since the 2 angles are supplementary,
(7x + 5°) + 28x = 180°.
=> 35x + 5° = 180°
=> 35x = 175°
=> x = 5°.
Hence Angle A = 7(5°) + 5° = 40°.
Similar triangles ABC and DEF are shown on the coordinate plane line t passes through points B, E, F, and C
Slope of BC = AB/AC, and Slope of EF = DE/DF
BC and EF both lie on the same line t, therefore the slope of BC equals the slope of EF.
What are Similar Triangles?Similar triangles are two triangles having the same shape but different sizes, however, the ratio of their corresponding sides are equal.
How to Find the Slope of a LineSlope = change in y / change in xSlope between any two points on the same line are the same.Given:
ΔABC ~ ΔDEF
Slope of BC = AB/AC
Slope of EF = DE/DF
BC and EF both lie on the same line t, therefore the slope of BC equals the slope of EF.

Find x & y so that quadrilateral is a parallelogram. (Look at image) please help!!
Answer:
y = 2 and x = -3
Step-by-step explanation:
we know that opposite sides of a parallelogram are equal so
7y + 3 = 12y - 7
12y - 7y = 3 + 7
5y = 10
y = 10 / 5
y = 2
Now
-6x = -4x + 6
-6x + 4x = 6
-2x = 6
x = 6 / - 2
x = - 3

Question
Express the inequality -2 8 using interval notation.
Provide your answer below:
B FEEDBACK
MORE INSTRUCTIO
Content attribution
Answer:
(-2, 8)
Step-by-step explanation:
To express any given inequality, note the following:
✔️< or > means the end value or the beginning value referred to is not included.
✔️ ≤ or ≥ indicates that the end of beginning value is included.
✔️ "( )" when used in writing an inequality in interval notation means an end or beginning value is not included.
✔️. "[ ]" means the end or beginning value is included.
Now let's express -2 < x < 8 using interval notation.
✅The beginning value is -2, which is < x. This means -2 is not included. Therefore, we would start our interval notation by stating this as: "(-2"
✅The end value is 8. x < 8. The "<" sign means 8 is not included. Thus, this statement would be expressed in interval notation as "8)"
✔️Combining both together, the inequality is experessed in interval notation as (-2, 8)

The top speeds for a sample of five new automobiles are listed below. Calculate the standard deviation of the speeds. Round to four decimal places. 170, 160, 130, 165, 125
Answer:
20.92
Step-by-step explanation:
Given the data:
X : 170, 160, 130, 165, 125
Standard deviation (s) :
s = √Σ((X - m)² / n)
m = mean
n = sample size
Mean , m = Σx/n
m = (170 + 160 + 130 + 165 + 125) / 5
m = 750/5
m = 150
((X - m)² / n - 1)
[(170-150)^2 + (160-150)^2 + (130-150)^2 + (165-150)^2 + (125-150)^2] / (5-1)
= 1750 / 4
= 437.5
s = √437.5
s = 20.9165
s = 20.92
lindsey made 400 tarts. she sold 3/5 of them in morning and 1/4 of the remainder in the afternoon. how many tarts did she sell in the afternoon?
Answer:
40 tarts
Step-by-step explanation:
Lindsey had 400 tarts to start with, then she sold off 3/5 of them. Hence find the number of tarts left (2/5 of the original amount). Then she sold 1/4 of the remaining tarts. Therefore, find 1/4 or 2/5 of 400. The equation would be;
[tex](\frac{1}{4})(\frac{2}{5})(400)[/tex]
Now one just has to solve the equation;
[tex]\frac{1}{10}(400)[/tex]

Find the volume, in cubic feet, of the composite solid below, which consists of a pyramid sitting on top of a cube. The pyramid has the same base as the cube.
Answer:
2,112 ft³
Step-by-step explanation:
Volume of composite solid = volume of pyramid + volume of cube
✔️Volume of square pyramid = ⅓(a²)*h
Where,
a = 12 ft
h = 8 ft
Plug in the values
Volume of pyramid = ⅓(12²)*8 = 384 ft³
✔️Volume of cube = a³
Where,
a = 12 ft
Plug in the value
Volume of cube = 1728 ft³
✔️Volume of composite solid = 384 + 1728 = 2,112 ft³
