Answer:
60
Step-by-step explanation:
hello there!
If you didn't know an exterior angle of a triangle is equal to the sum of its opposite interior angles
to be more specific ∠5=∠4+∠3
we are given ∠5 and ∠4 and we need to find ∠3
So we plug in what we have and solve for ∠3
130 = 70 + ∠3
subtract 70 from each side
130 - 70 = 60
we're left with ∠3 = 60

[tex](d)[/tex] [tex]\frac{4}{8}>\frac{2}{6}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{4} <\frac{1}{6}[/tex]
[tex]\frac{5}{10}<\frac{3}{6}[/tex]
[tex]\frac{1}{2}>\frac{1}{3}[/tex]
[tex]\frac{4}{8}>\frac{2}{6}[/tex]
[tex]\frac{3}{5}>\frac{4}{5}[/tex]
Required
Select the unit fractions
If we are to go by what a unit fraction means: it means that the numerator of the fraction must be 1 and must be written as a single fraction i.e. [tex]\frac{1}{2}[/tex] and not as an inequality i.e. [tex]\frac{3}{5}>\frac{4}{5}[/tex]
Given the format of the question, what is required of the question is to select all correct inequality.
[tex](a)[/tex] [tex]\frac{1}{4} <\frac{1}{6}[/tex]
Convert to decimals
[tex]0.25 < 0.167[/tex] ---- This is not true because [tex]0.25 > 0.167[/tex]
[tex](b)[/tex] [tex]\frac{5}{10}<\frac{3}{6}[/tex]
Convert to decimals
[tex]0.5 < 0.5[/tex] ---- This is not true because [tex]0.5 = 0.5[/tex]
[tex](c)[/tex] [tex]\frac{1}{2}>\frac{1}{3}[/tex]
Convert to decimals
[tex]0.5 > 0.33[/tex] ---- This is true
[tex](d)[/tex] [tex]\frac{4}{8}>\frac{2}{6}[/tex]
Convert to decimals
[tex]0.5 > 0.33[/tex] ---- This is true
[tex](e)[/tex] [tex]\frac{3}{5}>\frac{4}{5}[/tex]
[tex]0.6 > 0.8[/tex] --- This is not true because [tex]0.6 < 0.8[/tex]
So: the true inequality is:
[tex](d)[/tex] [tex]\frac{4}{8}>\frac{2}{6}[/tex]
A bus and a car both drive 145 miles from town A to town B. The bus drives 8 miles per hour faster than the car. If it takes the car 2 hours and 54 minutes to arrive, how long does it take for the bus to arrive?
Answers
Answer: 2.5 hours
Step-by-step explanation:
Given
Distance between A to B town is [tex]d=145\ miles[/tex]
Bus speed is 9 miles per hour faster than car
time taken by car is 2 hours and 54 minutes i.e.
[tex]t=2+\dfrac{54}{60}=2+0.9=2.9\ hr[/tex]
Speed of car is v
[tex]\Rightarrow v=\dfrac{d}{t}=\dfrac{145}{2.9}=50\ mph[/tex]
Speed of bus is [tex]v+8=50+8=58\ mph[/tex]
time taken by bus is t'
[tex]\Rightarrow t'=\dfrac{d}{v+8}=\dfrac{145}{58}=2.5\ hr\\\\\\\Rightarrow t'=2\ hr\ \text{and}\ 30\ \text{minutes}[/tex]

Answer:
B. 200 cubic feet
Step-by-step explanation:
There are two prisms: the triangular prism and the rectangular prism
first lets start with the triangular one:
remember that for a right triangular prism (this one), the area is 1/2 x base x height x length
another way to think about it is to find the area of the triangle and then multiply that by the thickness
The base is 4 feet and the height is the same as the rectangular prism, which is 5
and the length is 4 ft (same as rectangular prism)
so 1/2 x 4 x 5 x 4 is 40
next lets do the rectangular prism
remember the volume is length x width x height
8 x 4 x 5 = 160
now we simply add the volume of the two prisms
40 + 160 = 200
and there's you're answer :)
hope that helps!
Answer:
Step-by-step explanation:
Area of triangular face = 0.5×4×5 = 10 ft²
Volume of triangular prism = 10×4 = 40 ft³
Volume of rectangular prism = 8×4×5 = 160 ft³
Total volume = 40+160 = 200 ft³

Step-by-step explanation:
B shows a parabola, which is a quadratic equation, not a linear one.
The association between two numerical variables measured for the same individuals is displayed in a scatterplot. One variable's values are displayed on the horizontal axis, and the other variable's values are displayed on the vertical axis. On the graph, each individual in the data is represented by a point.
What is scatter plot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.

What is margin of error?In statistics, the margin of error is the level of inaccuracy in the findings of surveys using random samples. Less reliance on survey or poll results is indicated by higher statistical margins of error.
Given that,
[tex]\^p[/tex] = 0.5
1 - [tex]\^p[/tex] = 1 - 0.5= 0.5
margin of error = E = 5% = 0.05
At 90% confidence level

0.10/2 =0.05
Z/2 = 1.645 ( Using z table )
Sample size = n = (Z/2 / E)² x (1 - [tex]\^p[/tex])²
