Emily wants to cover her kitchen floor with ceramic tile. The diagram below shows the layout of her kitchen.
What is the area of her kitchen floor, in square feet, that will be covered with ceramic tile?
411 ft2
381 ft2
255 ft2
567 ft2
Answer:
381 ft
Step-by-step explanation:
first get the area of the kitchen
22 x 18= 396 ft
now get the area of the island which is 3x 5= 15 ft
to know how much she would need to cover (not including the island), subtract 396 to 15
that would be 381 ft
Jessica is returning home from a trip. The function d(t)=458-60t models the distance, in miles, that Jessica is from her house t hours after she began returning home. How far is Jessica from her home 5 minutes after she began returning home?
A.
5 miles
B.
158 miles
C.
300 miles
D.
453 miles
Answer: D. 453 miles .
Step-by-step explanation:
Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.
At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour [1 hour = 60 minutes],
Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]
[tex]=458-5=453\ miles[/tex]
Jessica is 453 miles from her home after 5 minutes she began returning home.
Hence, the correct option is D. 453 miles .
Rewrite the problem using fewer words. Leave out information that you do not need to solve the problem. Then solve the problem. For a science project, you record the high temperature each day. The high temperature on Day 1 was 6°less than on Day 4 and 4°less than on Day 10. The high temperature on Day 10 was 62°F. What was the high temperature on Day 1?
Answer:
Each day, you record the high temperature* (you don't necessarily need to say that it is for a science project). On Day 1, it was 4* less than Day 10**. It hit 62* F on Day 10. What was the high temperature on Day 1?
Because we know that on Day 1, the temperature was 4* less than on Day 10, and the high temperature on Day 10 was 62*, the high temperature on Day 1 was therefore 58*. Because 62 - 4 = 58.
Step-by-step explanation:
*You don't necessarily need to say that it was for a science project.
**The information for Day 4 is irrelevant too because we are not given the temperature for Day 4, therefore it does not help us find the answer.
Which equation represents a line with a slope of -6/5
and a y-intercept of 1?
Answer:
y = -6/5x + 1
Step-by-step explanation:
The equation that represents a line with a slope of -6/5 and a y-intercept of 1 is y = -6/5x + 1
How to determine the equation?The given parameters are:
Slope, m = -6/5y-intercept = 1Let the variable of the equation be x.
A linear equation is represented as:
y = Slope * x + y-intercept
So, we have:
y = -6/5 * x + 1
Evaluate
y = -6/5x + 1
Hence, the equation is y = -6/5x + 1

Identify the parent function.
a. cube root
b. reciprocal
c. square root
d. absolute value
Answer:
The answer is C. Square root
Step-by-step explanation:
The parent function of given graph is a square root function
The correct answer is an option (c)
What is a function?"It defines a relation between input and output values.""In function, for each input there is exactly one output."What is cube root?"The function of the form [tex]f(x)=\sqrt[3]{x}[/tex] "
What is reciprocal function?"This function obtained by finding the inverse of a given function."
What is square root function?"The function of the form [tex]f(x)=\sqrt{x}[/tex] "
What is an absolute value function?"The function of the form f(x) = |x| "
For given question,
We have been given the graph of a function.
We need to identify the parent function for the given the graph.
We can observe that the graph increases slowly.
The range of the function is set of all positive values.
We know that the range of square root function is always positive.
If we draw the graph for following functions
i) cube root function
ii) reciprocal function
iii) square root function
iv) absolute value function
Then the parent function of given graph is a square root function
Therefore, the correct answer is an option (c)

If 3(x + 5) = 39, then what is x?
Answer:
x=8
Step-by-step explanation:
X=8 because 39/3 is 13 and 13- 5 is 8 and 5 and 8 add up to make 13 inside the parenthesis.
x = 8
Explanation:3(x + 5) = 39Divide Both Sides By 33(x + 5) / 3 = 39 / 3
Simplifyx + 5 = 13
Subtract 5 From Both Sidesx + 5 - 5 = 13 - 5
