1c. Find the volume of the child's toy shown below. Use 3.14 for pi . Round all answers to 1 decimal place.
Please help!!!
Answers
The volume of top solid is 1570cm³, the volume of bottom solid is 157cm³and the total volume of toy is 1727cm³.
What are solids?Solids or three-dimensional shapes are defined as any shape or figure with three dimensions or more. Solid geometry is the study of the characteristics, volume, and surface area of three-dimensional shapes.
The toy can be divided into two solids :
The top solid is a cone and the bottom solid is a cylinder.
The total volume of the toy can be found by adding the volumes of the cone and cylinder.
Volume of cone
Length of the cone l= 13cm
The radius of the base of the cone r = 5cm
Height of cone h = = 12cm
Volume of cone = = = 1570 cm³
Volume of cylinder
Radius r = 5cm
Height h = 2cm
Volume of cylinder = = 157cm³
Therefore the total volume of toy = 1570 + 157 = 1727 cm³

If x is the least common multiple of the set {6, 8, 12} and y is the greatest common factor
of the set {20, 42, 72), what is the value of x/y ?
Answers
Answer:
12
Step-by-step explanation:
The least common multiple of {6,8,12} is 24. This can be intuitively figured by noting that any multiple of 12 is a multiple of 6 and that 12 is 1.5x larger than 8. That means we only have so multiple 12 by 2 and 8 by 3 for them to be equal. The GCF of {20,42,72} is 2 as the prime factorization of 20 is 2x2x5 and 42 is 2x3x7. That means even without having to check 72 (which is clearly even so 2 is a factor), we know that 2 is the greatest common factor that they could share. So X/Y = 24/2 = 12

What is the equation of a line that passes through the point (0, -2) and has a slope of -3?
y = -2
y = -2x - 3
y = -3x - 2
y = -3
Answers
Answer:
y = -3x - 2
Step-by-step explanation:
Since the line passes through the point (0, -2), -2 is the y-intercept
Using the slope-intercept form for a line we have
y = -3x - 2
Liz's math test included a survey question asking how many hours students spent studying for the test. The scatter plot below shows the relationship between how many hours students spent studying and their score on the test. A line was fit to the data to model the relationship.
Answers
Complete question :
Liz's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and regression line below show the relationship between how many hours students spent studying and their score on the test.
The fitted line has a slope of 15.
What is the best interpretation of this slope?
Answer:
C.)
The model predicts that the score will increase 15 points for each additional hour of study time.
Step-by-step explanation:
The slope of a regression line represents the rate of change :
From the formula :
Rise / Run = (y2 - y1) / (x2 - x1).
The slope is a Coefficient which shows how much the dependent variable changes per unit change in the independent variable.
Hence, for a slope value of +15, which is positive, meaning an increase ; then the score obtained will increase by 15 per additional unit increase in hour of study.
