In the figure shown above, all the corners form right angles. What is the area of the figure in square units?
9514 1404 393
Answer:
70 square units
Step-by-step explanation:
The overall outline is 15 units wide and 8 units high, for an area of ...
A = WH
A = (15 units)(8 units) = 120 units²
__
The white space taken out of that overall area is 5 units high and 15-4-1 = 10 units wide. The area of the white space is ...
A = (5 units)(10 units) = 50 units²
__
The shaded area is the difference between the overall area and the white space taken out:
shaded = 120 units² -50 units² = 70 units²

solve the inequality please
Answer:
The solution is 4 >/= -21
4 is greater than or equal to negative 21
Step-by-step explanation:
7x + 4 >/= 7(x - 3)
We'll start by distributing the y7 to the items in parentheses
7x + 4 >/= 7x - 21
Subtract 7x from both sides
4 >/= -21

6th grade, the problem solving is on the image
Answer:
y = x + 3
Step-by-step explanation:
Equation of the line can be written as y = mx + b (slope-intercept form)
Let's find the slope (m) and the y-intercept (b)
Slope (m) = change in y/change in x
Using two points on the line, (0, 3) and (1, 4),
Slope (m) = (4 - 3)/(1 - 0) = 1/1
m = 1
y-intercept (b) = 3 (the coordinate of the point where the y-axis is intercepted by ye line)
To write the equation, substitute m = 1 and b = 3 into y = mx + b
y = 1(x) + 3
y = x + 3

the area of a sector is a secotor = n/360 degrees pie r 2^ what does the term n/360 degrees
Answer:
4th option
Step-by-step explanation:
[tex]\frac{n}{360}[/tex] represents the fraction of the circle occupied by the sector , that is
The ratio of degrees in the sector's central angle to the total number of degrees in the circle
Option 4 is correct. The ratio of degrees in the sector's central angle to the total number of degrees in the circle.
What is the fraction?Fraction is defined as the number of composition constitute the Whole.
area of a sector is a secotor = n/360 degrees pie r^2
n =number of fraction at which the circle is divided
mean n = in degrees x number of angles.
and the ratio n/360 degrees
describes the number of partition to the circle.
Thus, the ratio n/360 degrees defines The ratio of degrees in the sector's central angle to the total number of degrees in the circle.

Solve for z 7-√3z+2=4 What is the root? If there is no root, choose none. z = 7/3 z = 11/3 none
Answer:
Desmos is Function Calculator is a great tool for this, the correct answer is z= 7/3
7/3= 2.333~ and so √(3*2.333~) + 2= 2.9999999833333~
Now 7- 2.9999999833333~= 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little weird, just plug (7/3) in for z and you will get 4, trust me

41. How would the graph of the function
y=x2- 3 be affected if the function were
changed to y=x2 + 2?
A. The graph would shift 2 units up.
B. The graph would shift 5 units up.
C. The graph would shift 5 units down.
D. The graph would shift 1 unit up,
Answer:
B. The graph would shift 5 units up.
Step-by-step explanation:
Before the change:
Before the change, the function was given by:
[tex]y = x^2 - 3[/tex]
After the change:
After the change, the function was given by:
[tex]y = x^2 + 2[/tex]
Considering the function as it was before the change, it can also be written as:
[tex]y = x^2 - 3 + 5[/tex]
Which means that 5 was added to the function, and when a number n is added to a function, there function is shifted n units up. So the correct answer to this problem is given by option B.
Mikos family drove at a constant speed as they left home and traveled to the restaurant where they stopped for lunch. Does the relationship between hours elapsed x and distance traveled y represent a proportional relationship? Explain why or why not
(100 points and brainliest)
Answer:
yes,
distance = time * speed
the more hours you spend in the road, the longer distance you took
Step-by-step explanation:
Answer:
Yes, the relationship between hours elapsed x and distance traveled y represent a proportional relationship.
Step-by-step explanation:
This is because he continuously stayed at a constant speed and didn't change. Once you stay at a constant speed then it will always be a proportional relationship.
The theater sells two types of tickets: adult tickets for $11 and child tickets for $9.
Last night the theater sold 262 tickets for a total of $2482. How many adult tickets did the theater sell last night?
Answer:
a=62
Step-by-step explanation:
11a + 9c=2482 equation 1
a + c = 262 equation 2
a=262-c isolate value of a in equation
11(262-c) + 9c = 2482 substitute value of a (262-c) into equation 2
2882-11c + 9c= 2482 solve
-2c=-400
c=200
a+c=262
a+200=262
a=62
Check answer:
11a + 9c=2482
11(62)+9(200)=2482
682+1800=2482
2482=2482
A survey was conducted to compare the mean cost of a meal at fast food restaurants in two different cities.
City n x s
A 26 $4.05 $0.55
B 32 $5.15 $0.85
Assume that the population variances of both groups are different. Test if there is sufficient evidence that the mean costs of a meal at fast food restaurants in two different cities are different. Conduct the hypothesis testing (optional) in paper.
Answer:
We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.
Step-by-step explanation:
Given :
City n x s
A 26 $4.05 $0.55
B 32 $5.15 $0.85
H0 : μ1 - μ2 = 0
H0 : μ1 - μ2 ≠ 0
n1 = 26 ; x1 = 4.05 ; s1 = 0.55
n2 = 32 ; x2 = 5.15 ; s2 = 0.85
Tstatistic :
(x1 - x2) / √(s1²/n1 + s2²/n2)
(4.05 - 5.15) / √(0.55²/26 + 0.85²/32)
-1.1 / 0.1849668
= - 5.947
Using the smaller n;
df = n - 1 ; 26 - 1 = 25
Pvalue = (-5.947, 24)
Pvalue = 0.000001
Since Pvalue < α ; We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.
prove that 1-cosA/sinA=cosecA-cotA
Answer:
See the proof below
Step-by-step explanation:
prove that 1-cosA/sinA=cosecA-cotA

cosecA-cotA
From trig identty
cosec theta = 1/sintheta and cot theta = cos theta/sin theta
Hence;
cosecA-cotA
= 1/sinA - cosA/sinA

what is the probability that the third spinner lands on a perfect square or a gray space?
6/12 or 1/2
Answer:
There are 6 gray spaces (12, 2, 4, 6, 8, 10) and 3 perfect squares (4, 9, 1). However, 4 is repetitive (it is gray and a perfect square) so there are only 8 we want. There are 12 numbers/spaces in total. The probability formula is (# of desired outcomes)/(# of total outcomes). In this case, there are 8 desired outcomes and 12 total outcomes. So, our answer is 8/12, or 2/3.
