Ten members of the Science Club went to a history muesum. It cost $7.25 for each member of the club. If 90 members went to the muesum, how much would the total cost?
Answer: $652.5
Step-by-step explanation:
If it costs $7.25 for each member of the club, we can multiply this unit value ($7.25) by 90 to find the total cost.
$7.25 * 90 = $652.5

9. The equation of the line parallel to y = 2x+4 and passing through the point (-4, -1) is y = 2 x +7
Given:
line = y = 2x+4
point = (x, y)= (-4,-1)
The given equation is of the form,
y = mx+ c ---- (1)
slope= m = 2
The line parallel to this line will have the same slope,
m = 2
The new line is of the form,
y = 2 x+ c ----(2)
Substituting the given point (-4, -1) in (2)
- 1= 2(-4) + c
c = 7
Substituting c in (2)
y = 2 x +7 is the parallel line equation.

is [tex]1.2345 \: repeating \: \times \sqrt{4} [/tex]irrational or rational?
If we can write this expression as a fraction, then this will be rational. Otherwise, irrational.
First, let's write the repeating decimal as fraction. Excluding the 1 point to the left of the decimal.
We have:
0.234523452345...
We can write it as:
[tex]\frac{2345}{9999}[/tex]Tagging along the "1", we have:
[tex]1\frac{2345}{9999}[/tex]Then, we have square root of 4, which is "2".
If we multiply the fraction shown above by 2, we will definitely have a fraction.
That will be a rational number.

ANSWER :
x = 33.6 degrees
EXPLANATION :
Recall that the cosine function is :
[tex]\cos\theta=\frac{\text{ adjacent}}{\text{ hypotenuse}}[/tex]From the problem, the adjacent to the angle x is 15 and the hypotenuse is 18.
Using the formula above :
[tex]\begin{gathered} \cos x=\frac{15}{18} \\ \\ \text{ take the arccos :} \\ x=\arccos(\frac{15}{18}) \\ \\ x=33.56\sim33.6 \end{gathered}[/tex]*GEOMETRY*please help me find the surface area of the solid along with the volume of it step by step!
Surface area of the solid = 7.1781 in²
Volume of the solid = 0.804 in³
Explanation:
Surface area of the solid = surface area of the square prism - 2(base of the cylinder) + lateral surface of cylinder
surface area of a square prism = 2(lw + lh + wh)
l = length = 1 in
w = length = 1 in
h = height = 1 in
[tex]\begin{gathered} \text{Surface area = 2(1}\times1\text{ + 1}\times1\text{ + 1}\times1) \\ \text{Surface area = 2(1 + 1 + 1) = 2(3)} \\ \text{Surface area = 6 in }^2 \end{gathered}[/tex]using the value π as it is on the calculator
Base area of a cylinder = πr²
2(Base area of cylinder) = 2πr² = 2π(0.25)² = 0.3927
Lateral surface area = 2πrh = 2π(0.25)(1) = 1.5708
Surface area of the solid = 6 - 0.3927 + 1.5708
Surface area of the solid = 7.178 in²
Volume of the solid = Volume of the square prism - volume of the cylinder
Volume of square prism = length × width × height
length = 1 in, width = 1 in, height = 1 in
Volume of the solid = 1 in × 1 in × 1 in = 1 in³
Volume of a cylinder = πr²h
Volume of the cylinder = π × 0.25 × 0.25 × 1 = 0.196
Volume of the solid = 1 - 0.196
Volume of the solid = 0.804 in³
The expression 81√ ⋅ 100√ represents the number of feet between home plate and first base. What is the distance, in feet, between home plate and first base?
Using perfect squares to solve the expression √81-√100 the distance between home plate and first base is 1 feet
Which numbers are perfect square?The perfect square is the number which can be written as the square of some integer.
A number x is a perfect square if x=y² for some y. or y =√x
Given:
The number of feet between home plate and first base = |√81-√100|
|x| absolute function is put because number of feet need to be a positive number
81 is a perfect square ∵ 81 = 9×9 = 9²
As 81 = 9²
⇒ √81 = √9² = 9
100 is also a perfect square ∵ 100= 10×10 =10²
As 100=10²
⇒ √100= √10² = 10
The expression √81-√100 = 9-10 = -1
The distance between home plate and first base = Number of feet between home plate and first base = |√81-√100| = |-1| = 1 feet

1. Andre is building a tower out of different foam blocks. These blocks come in three different thicknesses: -foot, -foot, and foot. Andre stacks two-foot blocks, two-foot blocks, and two-foot blocks to create a tower. What will the height of the tower be in foot? Explain or show how you know.
Height of the tower = 1.75 ft
Explanations:The thickness of the blocks are 1/2 ft, 1/4 ft, and 1/8 ft
Two 1/2 ft blocks will have a thickness of:
2 x 1/2 = 1 ft
Two 1/4 ft blocks will have a thickness of:
2 x 1/4 = 1/2 ft
Two 1/8 ft blocks will have a thickness of:
2 x 1/8 = 1/4 ft
The height of the tower = 1 + 1/2 + 1/4
The height of the tower = (4 + 2 + 1) / 4
The height of the tower = 7/4 = 1.75 ft

A model of a dinosaur was created using a scale factor of 1:20. The model is 3.75 feet long. How long is the actual dinosaur in feet?
ANSWER
75 feet
EXPLANATION
The scale factor means that the ratio of the model to the actual size of the dinosaur is 1 : 20.
The model is 3.75 feet long.
Let the actual length of the dinosaur be x.
So, it means that:
[tex]\begin{gathered} \frac{1}{20}\text{ = }\frac{3.75}{x} \\ \text{Cross}-\text{ multiply:} \\ 1\cdot\text{ x = 20 }\cdot\text{ 3.75} \\ x\text{ = 75 feet} \end{gathered}[/tex]The actual length of the dinosaur is 75 feet.

Suppose contact lenses cost $300 for a year’s supply or $30 for a month’s supply. Which is less expensive to order per year, paying for 12 months at one time or paying for 1 month at a time?
The cost that is less expensive is paying for 12 months at one time for $300.
How to calculate the value?From the information, contact lenses cost $300 for a year’s supply or $30 for a month’s supply.
In this case, for the $30 for a month’s supply, the amount that will be paid yearly will be:
= $30 × 12
= $360
In this case, the one time payment for $300 is cheaper.

What is the equation of the following line written in slope-intercept form.
y = 2 /3 x + 9 /2
y = 3 /2 x - 9 / 2
y = - 3 /2 x - 3 / 2
Answer:
y = -3/2x - 9/2
Step-by-step explanation:
The general form of a line in slope-intecept form is given by:
y = mx + c
where: m = slope, c = intercept.
from the graph, slope is calculated as:
m = (-3 - 0)/(-1 -(-3))
m = -3/2
To obtain c, choose any value of x, and corresponding y value.
we choose: (-3, 0)
using y = mx + c
0 = -3/2(-3) + c
simplify
c = -9/2
Therefore, y = -3/2x - 9/2

Which of the following symbol will make a true sentence when inserted in the blank?
5/7___0.6
a. <
b. >
C. =
Answer:
b: >
Step-by-step explanation:
We know that 4/6 = 2/3 = 0.6667
This is bigger than 0.6.
Since 5/7 > 4/6, we directly see that 5/7 > 0.6
In fact, 5/7 is approximately 0.714 which tells us that we have found the correct answer
Added: A better method might be: 5/7 = 10*5 / (7 * 10) = 50/70,
where 0.6 = 6/10 = 6*7/(10*7) = 42 / 70.
Since 50/70 > 42/70, it follows that 5/7 > 0.6 so B is the right answer
which system of linear equations has the ordered pair (-4,-12)as it's solution?
In order to find which system has the ordered pair (-4, -12) as a solution, let's check this pair in each system.
We can see that the first two options have the function x = (1/3)y and the last two have the function y = (1/3)x.
Looking at the ordered pair, we have that x is 3 times smaller than y, therefore the correct equation is x = (1/3)y.
Then, the second equation has a constant value for the sum "x + y".
Calculating x + y using the coordinates of the ordered pair, we have a value of -16.
Therefore the correct equation is x + y = -16.
So the option that has the correct system is the second one.

The domain of the inverse function f-1(x) is [-2, oo)
How to determine the representation of the domain of the inverse function ?The graph represents the given parameter
On the graph, we can see that:
The y values starts from y = -2 and it extends upwards to the positive axis
This means that the range of the function is
Range = [-2, oo)
When the function is inverted, the range becomes the domain
This implies that
Domain of the inverse function = Range of the function = [-2, oo)
Hence, the inverse function has a domain of [-2, oo)

Determine the x-intercepts of the graph represented by the following quadratic function. Recall that y = f(x).f(x) = x2 − 4x − 21(x, y) = (smaller x-value)(x,y)= (larger x-value)
For this problem, we are given the expression for a quadratic equation and we need to determine the x-intercepts of its graph.
The x-intercepts coincide with the zeros of the equation, which are obtained when f(x) = 0. So we have:
