What is the messure of angle 4
Answer:
m∠4 = 40°
Step-by-step explanation:
Using the vertical angle theorem we can find that...
m∠6 ≅ m∠7
[tex]11x+8=12x-4 \\ \\ x=12[/tex]
[tex]11(12)+8 \\ 132+8 \\ 140[/tex]
Using this, we know that angle 6 and 8 are supplementary so...
m∠6 + m∠8 = 180°
140° + m∠8 = 180°
m∠8 = 40°
Then, we can use the corresponding angle theorem to find that...
m∠8 ≅ m∠4
m∠4 = 40°
the measure of angle 4 is 40

Step-by-step explanation:
[tex]7\left(\sqrt[3]{2x}\right)-3\left(\sqrt[3]{16x}\right)-3\left(\sqrt[3]{8x}\right)[/tex]
WE need to simplify this equation.
Solve the parenthesis of each term.

F(x) = x^2. What is g(x)?
Answer:
The correct answer is C. g(x) = 1/4x^2
Step-by-step explanation:
In order to determine if the graph fits, take the point that is given on the parabola and see if it fits the equation. To do that we plug it in and see if it gives a true statement.
(2, 1)
g(x) = 1/4x^2
1 = 1/4(2)^2
1 = 1/4(4)
1 = 1 (TRUE)
Answer:
C, g(x) = 1/4x²
Step-by-step explanation:
the parent function of g(x) is the function f(x) = x² as shown on the graph
with the coefficient 1/4 in front of the parent function, we can determine its transformation.
it is a vertical shrink by 1/4 of the original graph. the reason why we know this is because a vertical shrink/stretch has a coefficient on the outside of the parent function (as shown in g(x)) and if we follow the rule:
b > 0 < this is a vertical stretch
b < 0 < this is a vertical shrink
b in this function is 1/4, which is less than 0

Solve 3^x+1 = 15 for x using the change of base formula log base b of y equals log y over log b
Answer:
x= 1.46497
Step-by-step explanation:
[tex]3^{x+1} = 15[/tex]
To solve this , first we convert the exponential form in to log form
[tex]if \ a^x=b \ then \ log_a(b)=x[/tex]
[tex]3^{x+1} = 15[/tex] becomes [tex]log_3(15)= x+1[/tex]
now we apply change of base formula to remove base 3
[tex]log_b(y)= \frac{log y}{log b}[/tex]
like that log_3(15) becomes
[tex]log_3(15)= \frac{log 15}{log 3}[/tex]
[tex] \frac{log 15}{log 3}= x+1[/tex]
2.46497=x+1
subtract 1 from both sides
x= 1.46497

A man can make 12 birdhouses in eight hours how many hours will it take to make 30
To find out how long it will take to make 30 birdhouses, first find the man's rate of work (1.5 birdhouses per hour) by dividing the total number of birdhouses he can make in eight hours (12) by the time (8 hours). Then divide the total number of birdhouses needed (30) by the rate to find the total time needed
Explanation:The question is asking how long it will take a man to make 30 birdhouses if he can make 12 birdhouses in eight hours. This is a classic rate problem in mathematics that can be solved by setting up a ratio. The first step is to find the rate of work that the man can perform. If the man can make 12 birdhouses in eight hours, then the man can make 1.5 birdhouses in one hour (12 birdhouses ÷ 8 hours).
Next, we want to find out how many hours it will take to make 30 birdhouses. Since his rate is 1.5 birdhouses per hour, we can divide the total number of birdhouses needed (30) by the rate (1.5 birdhouses per hour), which yields 20 hours.

x = 20 hours.
To find out how many hours it will take to make 30 birdhouses, we can set up a proportion using the given information:
12 birdhouses / 8 hours = 30 birdhouses / x hours
Cross multiplying gives us: 12 × x = 30 × 8
Therefore, x = 20 hours.
A cylindrical plastic pipe’s length is 12 cm and it’s radius is 2.5 cm. To the nearest tenth, what is the volume of the pipe?
Answer:
V = 235.6 cm³
Step-by-step explanation:
the formula for the volume of a cylinder of radius r and length h is
V = πr²h.
Here, r = 2.5 cm and h = 12 cm, so the volume is:
V = π(2.5 cm)²(12 cm) = 75π cm³
To the nearest tenth, this volume would be V = 235.6 cm³
Answer:
volume = 235.7 cm³
Step-by-step explanation:
To find the volume of the cylindrical plastic pipe, we simply use the formula:
volume of a cylinder = π r ² h
where r is the radius , and h is the height
From the question above, radius r = 2.5cm h =12 cm and π is a constant which is always equal to [tex]\frac{22}{7}[/tex] unless specified otherwise.
Now all we need to do is to insert our values into the formula;
volume of a cylinder = π r ² h
volume of a cylinder = [tex]\frac{22}{7}[/tex] × 2.5² × 12
= [tex]\frac{22}{7}[/tex] × 6.25 × 12
= [tex]\frac{1650}{7}[/tex]
= 235.714
≈235.7 cm³ to the nearest tenth
Therefore the volume of the cylindrical plastic pipe is 235.7 cm³

Logan bought 30 pounds of ground beef. He then cooks 12 pounds of it it for supper. The next day he cooks 17 pounds of the meat for lunch. How many pounds of ground beef does Logan has?
Answer:
1
Step-by-step explanation:
Logan bought 30 pounds of ground beef so then he cooks 12 pounds so 30-12=18
the next day he cooks 17 pounds of meat for lunch so 18-17=1
pls mark as brainliest
After cooking the beef for supper and lunch, Logan has 1 pound of
ground beef remaining.
Initial Amount: Logan bought a total of 30 pounds of ground beef.
Cooking for Supper: He cooked 12 pounds for supper.
To find out how much he has after this meal, we subtract the weight of
the cooked beef from the initial amount
[tex]30 \text{ pounds} - 12 \text{ pounds} = 18 \text{ pounds}[/tex]
Cooking for Lunch: The next day, he cooked 17 pounds for lunch.
We need to subtract this amount from the remaining beef:
[tex]18 \text{ pounds} - 17 \text{ pounds} = 1 \text{ pound}[/tex]

A single Rhinovirus is 2 × 10-8 meters long, and a single E. coli bacterium is 2 × 10-6 meters long. How many times larger is an E. coli bacterium than a Rhinovirus?
Multiply it by using scientific notation then multiply 2X0.00000010 and compare it to the coil which is 2X0.000010
Answer:
E coli bacterium is 200times larger than Rhinovirus
Step-by-step explanation:
Length of a single Rhinovirus is 2×10^-8m
Length of E coli bacterium is 2×10^-6m
This shows that E coli is larger than Rhinovirus.
To determine the number of times the E. coli bacterium is larger than a Rhinovirus, we will divide the length of E coli bacterium by that of single Rhinovirus to have:
2×10^-6/2×10^-8
= 2×10^(-6-(-8))
= 2×10^-6+8
= 2×10²
= 200
This shows that E coli bacterium is 200times larger than Rhinovirus
