Sandra brings 6 dolls to her grandma's house. These dolls represent 60% of her collection, as shown in the diagram. What is the total number of dolls in Sandra's collection.
Answer:
10
Step-by-step explanation:
60% of 10 is 6, so if 6 is 60% then 100% of them would be 10

Step-by-step explanation:
Sum exterior measure = ( n-2)*180
( n-2 ) *180
(3-2)*180
180
x+4x-2+5x = 180
10x-2 = 180
10x = 180+2
10x = 182
x = 18.2
A = x
A = 18.2°
B=5x
B = 5(18.2)
B = 91°
C = 4x-2
C = 4(18.2)-2
C = 72.8-2
C = 70.8°

The Pythagorean theorem states that a² + b² = c² for a right triangle with leg lengths, a and b, and hypotenuse length, c.
The hypotenuse of a right triangle is 5 units long and has the points (3, 0) and (0, 4) as end points. One of the legs has length 3.
Use the Point and Segment tools to draw a right triangle at demonstrates the other leg length is 4.
Answer:
Step-by-step explanation:
Draw the third point at (0, 0). This would make the distance from (3,0) to (0,0) equal to 3, and the distance from (0,4) to (0,0) be 4.

A car manufacturer claims that the company’s newest model has a peak power of exactly 329 horsepower. Katherine is a reporter for an automotive magazine. She is testing the manufacturer's claim and says that the population mean peak power is less than the advertised amount. She measures the peak horsepower of 42 randomly selected cars of the new model. The sample mean is 327.74 horsepower with a standard deviation of 2.41 horsepower. Should Katherine reject or fail to reject the null hypothesis given the sample data below? H0:μ=329 versus Ha:μ<329 α=0.05 (significance level) t≈−3.39 with 41 degrees of freedom p-value<0.005
Answer: Katherine should reject the null hypothesis.
Step-by-step explanation:
We reject the null hypothesis when p-value is less than the significance level.
here, H0:μ=329 versus Ha:μ<329
α=0.05 (significance level)
p-value<0.005
so , we should reject the null hypothesis as p-value is less than the significance level.
Hence, Katherine should reject the null hypothesis.

All equilateral triangles are ____
triangles
A. Right
B. Acute
C. Scalene
D. Obtuse
Answer:
Acute
Explanation:
Due to the fact that all the angles of an equilateral triangle have a measure of 60 degrees, the triangle must be acute as the measure of all acute angles are less than 180 degrees.
Answer:
Option B
Step-by-step explanation:
All equilateral triangles are "acute triangles" or option B. Acute triangles have degrees that are less than the degree of a right triangle which is 90 degrees. In this case all equilateral triangles have the sum of 60 degrees, which is less than the degree of a right triangle which means it is indeed a acute angle. It's not option D because obtuse triangles are triangles with angles that are more than 90 degrees, it's also not option C because each side of a scalene triangle is of different length in terms of degrees.
Hope this helps.

A motorboat takes 3 hours to travel 108 kilometers going upstream. The return trip takes 2 hours going
downstream. What is the rate of the boat in still water and what is the rate of the current?
Answer:
45 km/h and 9 km/hStep-by-step explanation:
Let the rate of boat in still water be b and the speed of the current be c
Speed downstream = b + cSpeed upstream = b - cWe got equations for time:
108/(b - c) = 3 ⇒ b - c = 36108/(b + c) = 2 ⇒ b + c = 54Add up the equations:
b - c + b + c = 36 + 542b = 90b = 45 km/hThen finding the values of c
c = 45 - 36 = 9 km/hAn art teacher had 2/3 gallon of paint to pour into containers. If he poured 1/8 gallon of paint into each container untill he ran out of paint. How many containers had paint in them including the one that was partially filled

In all, 54 children were assigned to the Montessori school and 115 to other schools at age three. When the children were five, parents of 38 of the Montessori children and 34 of the others could be located and agreed to and subsequently participated in testing. This information reveals a possible source of bias in the comparison of outcomes. Explain why. (Round your answers to the nearest whole number.) About % of Montessori parents participated in the study, compared to about % of the other parents. (c) One of the many response variables was score on a test of ability to apply basic mathematics to solve problems. Here are summaries for the children who took this test:
Full question attached
Answer:
Option C: because the percent of children compared differ too much
Explanation:
Sample Proportion of students from Montessori = students that participated from Montessori /total number of students assigned to Montessori
=30/54= 0.56
Sample proportion of students from other schools = students that participated I'm the study /total number of students assigned to other schools
=25/112
=0.22
We observe that there is a large difference(0.56-0.22) between the two sample proportions hence the bias
For each part, first decide which of the three methods sections will most easily enable you to sketch the surface. These are the generalized cylinder method, the surface of revolution method, and the method of slices (traces) for general quadric surfaces. Then apply that method to sketch the surface.
a. x^2 = 4z +8
b. x^2 - 4y^2 – 4z^2 = 16
c. y^2 = x^2 + 2z^2
Answer:
Step-by-step explanation:
We use these three methods
1. Generalized cylinder method
2. Surface of revolution method
3. Method of slices general quadratic
1. For A = x² = 4z + 8
We use the method of slices for general quadratic
2. X²-4y²-4z² = 16
We use the generalized cylinder method
3. Y² = z² + 2z²
We use surface of revolution

Given that f(x) = 3x + 2 and h(x) = x3, find (h o f)(2).
Answer/Step-by-step explanation:
This is what we know...
f(x) = 3x + 2 and h(x) = 3x and that h(2) or x=2
Given that info we can input our values into the variables.
f(2) = 3(2) + 2
Now according to the Order of Operations, we should multiply next.
f(2) = 6 + 2
Now according to the Order of Operations, we should add.
f(2) = 8
I don't know if your question wants it as a ordered pair or not so ignore this if there is any of those. The answer in an ordered pair would be (2,8)
Now we have to do the other equation.
Input our values into the variables
h(2) = 3(2)
Now according to the Order of Operations, we should multiply next.
h(2) = 6
I don't know if your question wants it as a ordered pair or not so ignore this if there is any of those. The answer in an ordered pair would be (2,6)
Hope this Helps! :)

28y^2 - 23y + 4 /28y^3 + 19y^2 - 20y
Answer:
42y^2 - 43y + 1/7y^3
Step-by-step explanation:
Solve the following system of equations two ways:
First solve using elementary row operations (you may use back-substitution if you like). Make sure you annotate your work clearly.
Second solve by expressing the system as a matrix equation of the form Ax=b (make sure you provide some explanation of where this matrix comes from.), find A^-1, and then multiply both sides of the equation with A^-1.
Here is your system of equations:
x + y - 2 = 4
2x – y + z = 2
-3x + y + 5z = 2

Which sequences are geometric? Select three options.
Answer:
there are no sequences pls edit or repost so i can help : )
Please answer these two questions!
Answer:
the answer is B. this is because since they are on the same horizontal line, the distance is the value of the 3 plus the value of 6. so 6+3=9.
If you think about it in positives like 5 and 2, you'd subtract to get that the distance is 3. It's the same for -6 and 3.
Let's find
(-6,4)(3,4)y=4

|-6|+36+39unitsWhat is the vertex of this
quadratic function?
y = 4(x-3)2 – 8
Answer:
The vertex of [tex]y = 4\, (x - 3)^{2} - 8[/tex] is at [tex](3,\, -8)[/tex].
Step-by-step explanation:
Consider a quadratic function with the point [tex](h,\, k)[/tex] as the vertex (for some constants [tex]h[/tex] and [tex]k[/tex].) It would then be possible to express this function in the vertex form [tex]y = a\, (x - h)^{2} + k[/tex] for some constant [tex]a[/tex] where [tex]a \ne 0[/tex]. (Note the minus sign in front of [tex]h[/tex].)
For example, the quadratic function [tex]y = 4\, (x - 3)^{2} - 8[/tex] in this question is expressed in this vertex form:
[tex]y = 4\, (x - 3)^{2} + (-8)[/tex].
The values of [tex]h[/tex] and [tex]k[/tex] are [tex]h = 3[/tex] and [tex]k = (-8)[/tex], respectively. Thus, the vertex of this parabola would be at the point [tex](3,\, -8)[/tex].
Answer:
[tex]\displaystyle [3, -8][/tex]
Explanation:
First off, this equation came from the quadratic equation [tex]\displaystyle [y = Ax^2 + Bx + C],[/tex]in which it was [tex]\displaystyle y = 4x^2 - 24x + 28.[/tex]In the vertex equation [tex]\displaystyle [y = A(x - h)^2 + k],[/tex]the vertex is represented by [tex]\displaystyle [h, k],[/tex]in which −h gives you OPPOCITE TERMS OF WHAT THEY REALLY ARE, so be careful there.
