Answer:
C=20
Step-by-step explanation:
This is for question 3
For perpendicular lines , the product of their gradient should give -1 for the answer and thus,
3×x=-1
x=-⅓, the gradient for the line.
Therefore c =
-2-3/c- 5 =-⅓
-1(c-5)=3(-2-3)
-c+5=-6-9
-c=-6-9-5
-c=-20
The negatives cancel each other leaving c as 20

My Samsung charger broke so I went to Five Below to get a new one. They were on sale for $15,35 (not so five below). There
was a 6% tax too. How much did the new charger cost?
( I don’t need the explanation, only the right answer)
Answer:
The answer to your question is 16.27
Explanation:
You would start with the equation,
15.35 + 6% = C (Cost)
15.35 · 6% = 0.921
15.35 + 0.921 = 16.271
Round the one down, since it is less than four, and you get 16.27

Answer:
1) A segment is a "part" of a line that is delimited by two points, such that it starts in a point and ends in another.
In segments the "endpoints" can commute, so is the same DA as AD.
In the image we can see 3 segments:
DA
AS
DS
2) A ray starts in a point and passes through another point, extending infinitely.
In this case, the ray DA is different than the ray AD, because the ray DA starts in D and extends to the right (because point A is at the right of point D) infinitely.
And the ray AD starts in A and extends to the left infinitely (because point D is at the left of point A).
Also, because A and S are colinear, the rays:
ray DA = ray DS
Both of them start on D and extend infinitely to the right.
Then the rays we can see on this image are:
ray DA = ray DS
ray AS
ray SA = ray SD
ray AD.
4 rays in total.
3) The names of the segments are the ones we wrote in point 1.
DA
DS
AS
4) The segment that connects point D with point S is the segment DS.
5) The ray AS starts at A and goes to the right, then the one that goes toward the opposite of AS would be one that starts at A and goes to the left.
That one is the ray AD.
Izzy has 354 grapes and 600 red grapes. The man in the store is selling apples. How many grapes are there in all?
.
Sadie buys milk and apples at the store.
She pays a total of $47.92.
She pays a total of $3.05 for the milk.
She buys 7 bags of apples that each cost the same amount.
How much does each bag of apples cost?
Answer:
$6.41
Step-by-step explanation:
47.92 - 3.05 = 44.87
44.87/7 = $6.41
Identify the figure, name the bases,faces,edges, and vertices
Answer:
It’s a square-based pyramid
base(1) is the square on the bottom- ABCD
Faces(4) are the triangles on the sides eg- AED, DEC, CEB, BCA
There are 8 edges, four being at the bottom around the base and the other four being alone the faces
Finally there are 5 vertices, four being at the corners of the base and the fifth being the tip of the pyramid

The top of the cake to be triangular with one side length 10cm, one side length 12cm and a 90-degree angle between these sides
Answer:
See attachment
Step-by-step explanation:
Given
[tex]Side\ 1 = 10cm[/tex]
[tex]Side\ 2 = 12cm[/tex]
[tex]\theta = 90^\circ[/tex]
Required [Missing from the question]
Draw the top of the cake
See attachment for reference.
From the attachment,
[tex]2cm = 1\ unit[/tex]
So:
[tex]Side\ 1 = 10cm[/tex]
[tex]Side\ 1 = 5 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 1 = 5 * 1unit[/tex]
[tex]Side\ 1 = 5\ units[/tex]
[tex]Side\ 2 = 12cm[/tex]
[tex]Side\ 2 = 6 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 2 = 6 * 1unit[/tex]
[tex]Side\ 2 = 6\ units[/tex]
This means that, the given side lengths will be represented by 5 units and 6 units on the grid, respectively.

A rectangle with area 36 square inches has a length that is 3 less than 3 times the width. Find the length and the width of the rectangle.
Answer:
length = 9 in ; width = 4 in
Step-by-step explanation:
1) formula of the area of a rectangle
A = base x width
2) write an equation with the given informations:
w x (3w-3) = 36
3) solve the equation
- multiply W by 3w and -3
3w^2 -3w = 36
- divide the two members by 3
w^2 - w = 12
- add up -12 at the two members
w^2-w -12 = 12 -12
w^2 - w - 12 = 0
- find two numbers whose sum is -1 and whose product is -12 and factorise the equation
(w-4)(w+3) = 0
- find the two solutions
w-4 = 0
w = 4
w+3 = 0
w = -3
4)remember that a length can’t be negative.
w = 4 is the only solution
5) find the length
4x3 - 3 = 9

An endocrinologist is interested in the effects of depression on the thyroid. It is believed that healthy subjects have a mean thyroxin (a hormone related to thyroid function) level of 7.0 micrograms/100 ml and a standard deviation of 1.6 micrograms/100 ml. The endocrinologist wants to assess whether the mean thyroxin level is different for those with depression. She samples 35 subjects with depression and obtains a sample mean of 7.82 micrograms/100 ml for thyroxin. What null and alternative hypotheses should she test
Answer:
H0: μ = 7.0
H1: μ > 7.0
Step-by-step explanation:
The null hypothesis will equal and take up the value of the population mean value ;
The population mean value, μ is 7.0
Null hypothesis ; H0: μ = 7.0
The alternative hypothesis will align with the claim ; which will take up and side with the value and direction of the sample mean ; 7.82 micrograms/100 ml
7.82 > 7.0 (sample mean is greater Than the population mean).
Hence, the alternative hypothesis, H1 will be ;
H1 : μ > 7.0
