Answer:
squid, crab, tuna, eel
Step-by-step explanation:
Just make each sushi piece into an equation, then solve it.
For example, for the squid: (s stands for squid)
[tex]2s = 3.5\\ s=1.75[/tex] Divide both sides by 2 to get "s" by itself
Eel: (e stands for eel)
e = 3.25
Tuna: (t stands for tuna)
[tex]3t=6.75\\ t=2.25[/tex] Divide both sides by 3 to get "t" by itself
Crab: (c stands for crab)
[tex]4c=8\\ c=2[/tex] Divide both sides by 4 to get "c" by itself
**Then order from least to greatest**

Seventy-five 6 th-grade students chose to watch a movie on the last day of school. This is 25% of the 6 th-grade class. How many total students are in the 6 th grade?
The total number of students in the 6th grade is 300.
What is a percentage?A percentage is a number or ratio expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
For the given situation,
25% of the 6th-grade class students is 75
Let x be the total number of students, say 100%.
⇒ [tex]25\%=\frac{1}{4}[/tex]
Here, 1 part is 25% then 4 parts are 100%
Thus 1 part = 75, then
⇒ [tex]4 parts = 4(75)[/tex]
⇒ [tex]4 parts = 300[/tex]
Hence we can conclude that the total number of students in the 6th grade is 300.

Which shape could be thought of as being created by stacking congruent polygons?
cone
rectangular prism
square pyramid
triangular pyramid
Answer:
its B
Step-by-step explanation:
Final answer:
A rectangular prism can be thought of as being created by stacking congruent polygons, as its faces are identical rectangles or squares. Pyramids, on the other hand, have a consistent base but their side faces are triangles that converge, not congruent polygons. A cone does not consist of stacking polygons since it has a continuous curved surface.
Explanation:
The shape that could be thought of as being created by stacking congruent polygons is the rectangular prism. When you stack identical polygons directly on top of each other, you are essentially creating the sides of a prism. Rectangular prisms are made up of congruent rectangles (or squares if it's a cube). Each face is identical, and they are stacked in a way that the height of the prism adds dimensionality but does not change the consistency of each face being a congruent polygon.
In contrast, when you consider shapes like pyramids, they do not have congruent faces all around. For example, a square pyramid has a square base, but the side faces are triangles that converge at a point. Similarly, a triangular pyramid (also known as a tetrahedron) also does not have congruent faces all around since it consists of equilateral triangles that meet at a point. The cone is a special case where the base is a circle (an infinite number of infinitesimally small sides), and the surface is a continuously curved shape, so it does not consist of stacking congruent polygons.
Suppose a parabola has vertex (–8, –7) and also passes through the point (–7, –4). Write the equation of the parabola in vertex form.
a.y=(x+8)^2-7
b.y=3(x-8)^2-7
c.y=3(x+8)^2-7
d.y=3(x+8)^2+7
We have been given that a parabola has vertex [tex](-8,-7)[/tex] and also passes through the point [tex](-7,-4)[/tex]. We are asked to write the equation of the parabola in vertex form.
We know that vertex form of parabola in format [tex]y=a(x-h)^2+k[/tex], where point (h,k) represents vertex of parabola.
Let us write equation of parabola using our given information as:
[tex]y=a(x-(-8))^2-7[/tex]
[tex]y=a(x+8)^2-7[/tex]
Now we will substitute the coordinates of point [tex](-7,-4)[/tex] to solve for a as:
[tex]-4=a(-7+8)^2-7[/tex]
[tex]-4=a(1)^2-7[/tex]
[tex]-4=a-7[/tex]
[tex]-4+7=a-7+7[/tex]
[tex]3=a[/tex]
Therefore, our required equation would be [tex]y=3(x+8)^2-7[/tex] and option 'c' is the correct choice.

Answer:
Step-by-step explanation:
its 1
The given function f(x) = (1/4)ˣ, the initial value of the function when x is substituted in the function is , 1
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
Graph of function f(x) = (1/4)ˣ
when value of x is substituted in given function,
f(0) = (1/4)⁰
f(0) = 1
So, the initial value of the function is 1

A. David notices that the shape of the Ligersville toxic dumpsite is somewhat like a triangle. He claims that he can approximate the perimeter of the dumpsite without doing any extra measurements. What assumption about side AB of the dumpsite would David need to make in order to justify his claim?
B. Based on the assumption in part A, determine the approximate length of side AB of the dumpsite. Explain your reasoning in at least two sentences.
C. Determine the approximate perimeter of the Ligersville toxic dumpsite. Explain your reasoning.
Answer:
A) AB is approximately straight line
B) 40 yards
C) 96 years
Step-by-step explanation:
A) For the toxic dump site to be traingular, AB must be a straight line to form hypotneuse of the traingle and that the traingle is right angle triangle
B) assuming a right angle triangle, using pythagoras theorem
H²=P²+B²
H²= 24²+ 32²
H= 40 yards
C) Parameter= 24+32+40=96 yards
Answer:
A. Side AB is approximately straight and forms the hypotenuse side of the right triangle
B. 40 yards
C. 96 yards
Step-by-step explanation:
A. The assumption about the curved side AB that David would need to make in order to justify his claim is that the side AB is straight and is the hypotenuse side of the right triangle.
B. The length of AB is thus;
√(24² + 32²) = 40 yard
C. The approximate perimeter is therefore;
24 + 32 + 40 = 96 yards
Suppose ACT Reading scores are normally distributed with a mean of 21.4 and a standard deviation of 5.9. A university plans to award scholarships to students whose scores are in the top 9%. What is the minimum score required for the scholarship? Round your answer to the nearest tenth, if necessary.
To find the minimum score required for the scholarship, we need to find the z-score that corresponds to the top 9% of the normal distribution.
Explanation:To find the minimum score required for the scholarship, we need to find the z-score that corresponds to the top 9% of the normal distribution.
Step 1: Convert the top 9% to a z-score using the standard normal distribution table.
Step 2: Use the z-score formula to find the corresponding ACT Reading score.
Step 3: Round the answer to the nearest tenth.
The minimum score required for the scholarship is the score that corresponds to the z-score found in Step 1.
To be in the top 9% for ACT Reading scores, a student needs a minimum score of approximately 29.3.
To determine the minimum ACT Reading score required for the top 9%, we need to find the z-score that corresponds to the 91st percentile in a standard normal distribution. According to z-tables, the z-score for the 91st percentile is approximately 1.34.
Next, we use the z-score formula to find the required ACT score:Formula:⇒ Z = (X - μ) ÷ σ
Given values:⇒ Mean (μ) = 21.4,
⇒ Standard Deviation (σ) = 5.9,
⇒ Z = 1.34
Solve for X:⇒ X = Z × σ + μ
⇒ 1.34 × 5.9 + 21.4 = 7.906 + 21.4
≈ 29.3
Therefore, to be in the top 9%, the minimum ACT Reading score required is approximately 29.3.

What is the measure of angle 4?
Answer:
45 degrees
Step-by-step explanation:
∠1 and ∠4 are on a straight line. Therefore, they are supplementary and add to 180 degrees.
∠1+∠4=180
We know that the m∠1 is 135 degrees. We can substitute 135 in for ∠1.
135+∠4=180
Now we have to solve for ∠4. To do this, we need to get ∠4 by itself. 135 is being added on to ∠4. To undo this, subtract 135 from both sides, because subtraction is the opposite of addition.
135-135+∠4=180-135
∠4=180-135
∠4=45
The measure of ∠4 is 45 degrees.

Why?[Contractions] AA woman's feedback system goes haywire when she goes into labor incorrect answer BThough painful, the contractions help women give birth incorrect answer CThe feedback system also releases special hormones to kill the pain incorrect answer DThe baby's feedback system causes the contractions to continue, not the mother's feedback system
Answer:
the correct answer is b.) though painful, the contractions help women give birth
Step-by-step explanation:
The contractions in labor are part of a feedback system involving the uterus, hypothalamus and posterior pituitary gland, resulting in the release of oxytocin. This hormone triggers increased uterine contractions which helps in the birthing process, continuing until the baby is born.
Explanation:The contractions experienced by women in labor, despite being painful, are a necessary part of the birth process, and the body has a feedback system that encourages this process to continue. The basis for this is a feedback relay between the uterus, hypothalamus, and the posterior pituitary gland in the brain. The first contractions of labor, which are the stimulus, push the baby toward the cervix, the lowest part of the uterus. The cervix contains stretch-sensitive nerve cells that monitor the degree of stretching, these sensors then send messages to the brain, which in turn causes the pituitary gland at the base of the brain to release the hormone oxytocin into the bloodstream.
Oxytocin causes stronger contractions of the smooth muscles in the uterus, which are the effectors, pushing the baby further down the birth canal. This causes even greater stretching of the cervix. The cycle of stretching, oxytocin release, and increasingly more forceful contractions only stops when the baby is born. At this point, the stretching of the cervix halts, thereby stopping the release of oxytocin.
