Answer:
-0.753Step-by-step explanation:
Given
log₃4 ≈ 1.262 and log₃7 ≈ 1.771To find
log₃(7/16)Solution
log₃(7/16) = log₃7 - log₃16 = log₃7 - 2log₃4 =1.771 - 2*1.262 = -0.753So
log_3(7/16)log_3(7)-log_3(16)log_3(7)-log_3(4²)log_3(7)-2log_3(4)1.771-2(1.262)-0.753A bus travels two different routes: the Green Route and the Blue Route. The routes are different lengths.
● On Monday the bus traveled the Green Route 6 times and the Blue Route 5 times, traveling a total of 52
miles.
● On Tuesday the bus traveled the Green Route 12 times and the Blue Route 13 times, traveling a total of
119 miles.
What is the length of the Green Route in miles?
A .4.4 mi
B. 4.5 mi
C. 6.4 mi
D. 6.8 mi
Answer:
B. 4.5 mi.
Step-by-step explanation:
Let g = length of green route
b = length of blue route
(1) 6g + 5b = 52 (2) 12g + 13b = 119
Mult. (1) by -2 -12g - 10b = -104
3b = 15
b = 5
6g + 5(5) = 52
6g + 25 = 52
6g = 27
g = 27/6 = 9/2
The length of the Green route is 4.5m and the length of the Blue route is 5m and this can be determined by forming the linear equation.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
On Monday the bus traveled the Green Route 6 times and the Blue Route 5 times, traveling a total of 52 miles.
On Tuesday the bus traveled the Green Route 12 times and the Blue Route 13 times, traveling a total of 119 miles.
Let the length of the Green route be 'a' and the length of the Blue route be 'b' then on Monday bus traveled:
6a + 5b = 52 ---- (1)
On Tuesday the bus traveled:
12a + 13b = 119 ----- (2)
Now, solve the equation (1) for 'a'.
a = (52 - 5b) /6 ------ (3)
Now, put the value of 'a' in equation (2).
12 (52 - 5b) / 6 + 13b = 119
b = 5 m
Now, put the value of b in equation (1).
6a + 5b = 52
a = 4.5 m

Answer:
A = 65, B = 75
Step-by-step explanation:
x + x + 10 + 40 = 180
2x + 50 = 180
2x= 130
x = 65
Answer:
∠A = 65°
∠B = 75°
Step-by-step explanation:
The sum of all the angles in a triangle is 180°, so we need to add all of the angles and make them equal to 180, then solve for "x".
x + x + 10 + 40 = 180
2x + 50 = 180
2x = 130
x = 65
Now, we replace "x" with 65 to get ∠A and ∠B.
∠A = x = 65°
∠B = x + 10 = 65 + 10 = 75°

ME NEED HELP HERE SO CONFUSED
Answer:
106°
Step-by-step explanation:
By exterior angle theorem:
[tex]m \angle \: 1 = 62 \degree + 44 \degree \\ \\ m \angle \: 1 = 106 \degree[/tex]
Step-by-step explanation:
Let the unknown angle in the triangle be x.
x + 44 + 62 = 180(sum of angles in a triangle)
x + 106 = 180
x = 180 - 106
x = 74
Angle 1 + x = 180 (Sum of angles on the same straight line)
angle 1 + 74 = 180
Angle 1 = 180 - 74
= 106

The run is the__
change between two points on a line.
A. rising
B. horizontal
C. average
D. vertical
Answer:
Horizontal
Step-by-step explanation:
The mathematical definition of slope is very similar to our everyday one. In math, slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run.
This February only one quarter of the days had an average temperature above freezing (32 degrees). How many days in February were below freezing?
Answer:
21 days
Step-by-step explanation:
February has 28 days
28/4=7
1 quarter of 28 is 7
Since one quarter was above freezing, 3 were below freezing
3x7=21
21 days is the final answer
Answer:
21 days
Step-by-step explanation:
There are 28 days in February.
If one quarter of the days had a temperature above freezing, that means that three quarters of the days had a temperature below freezing.
Find how many days were below freezing by multiplying 28 by 3/4
28(3/4)
= 21
So, 21 days in February were below freezing.

A sphere has a surface area of 803.84 cm^2. What is the volume?
Answer:
V≈2143.03cm³
Step-by-step explanation:
The volume of the sphere is 2143.57 cm³.
What is the surface area of the sphere?A = 4 × π × r², where 'r' is the radius of the sphere.
What is the volume of the sphere?V = (4/3) × π × r³
For given example,
a surface area of the sphere is 803.84 cm^2.
⇒ A = 803.84 cm²
Using the formula of the surface area of the sphere,
⇒ 4πr² = 803.84
⇒ r² = 64
⇒ r = 8 cm
Using the formula of the volume of the sphere,
⇒ V = (4/3) × π × r³
⇒ V = (4/3) × 3.14 × 8³
⇒ V = 2143.57 cm³
Therefore, the volume of the sphere is 2143.57 cm³.

Answer:
117 ft³
Step-by-step explanation:
The tent is composed of a cuboid and a triangular prism
V ( cuboid) = 6 × 8 × 2 = 96 ft³
V(prism) = Ah ( A is the area of triangle and h is length )
= [tex]\frac{1}{2}[/tex] × 6 × (5.5 - 2) × 2

A function g models a relationship in which the dependent variable doubles for every 3 units the independent variable increases.
Answer:
x-intercept = 3
y-intercept = -2
Step-by-step explanation:
P.S - The exact question is -
Given - A function g models a relationship in which the dependent variable doubles for every 3 units the independent variable increases.
To find - Graph g when g(0) = -2. Identify the y-intercept and x-intercept.
Proof -
By using the given information , we get
g(x) = [tex]\frac{2}{3} x - 2[/tex]
g(0) = 0 - 2 = -2
It also satisfy the condition g(0) = -2
Here,
by comparing with general form of slope-intercept form y = mx + c
where m = slope, c = y-intercept
Slope, m = [tex]\frac{2}{3}[/tex]
For x-intercept,
Put y = 0
⇒[tex]\frac{2}{3} x - 2[/tex] = 0
⇒[tex]\frac{2}{3}x = 2[/tex]
⇒x = 3
So,
x-intercept = 3
For y-intercept,
Put x = 0
⇒y = 0 - 2
⇒y = 2
∴
y-intercept = -2
A pool is 6/7 full of water. If 1/6 of the water leaks out, how full will the pool be?
Subtract 1/6 from 6/7
First rewrite the fractions to have a common denominator:
6/7 = 36/42
1/6= 7/42
Now you have 36/42 - 7/42 = 29/42
The pool is 29/42 full
You receive an A 40% of the time, a B 20% of the time, a C 15% of the time , and a D the rest of the time. For any random test, what is your expected grade point average? (Use the following values for X: A=4, B=3, C=2, D=1)
The grade you receive on a test is a discrete random variable with probability mass function
[tex]f_X(x)=P(X=x)=\begin{cases}0.4&\text{for }X=4\text{ (i.e. scoring an A)}\\0.2&\text{for }X=3\text{ (B)}\\0.15&\text{for }X=2\text{ (C)}\\0.25&\text{for }X=1\text{ (D)}\\0&\text{otherwise}\end{cases}[/tex]
where the probability of getting a D is 25% because there are only 4 possible grades, and the probabilities must sum to 1 :
0.4 + 0.2 + 0.15 + 0.25 = 1
The expected test score/GPA is then
[tex]\displaystyle\sum_x x\,f_X(x)=\sum_{x=1}^4 x\,P(X=x)=1\cdot0.25+2\cdot0.15+3\cdot0.2+4\cdot0.4=\boxed{2.75}[/tex]
so your average would fall between a B and a C.
