Answer:
7640 Students are Girls
Step-by-step explanation:
10% of all students is 1,910
We know 60% is male so we do 1910 x 6 = 11460
Now we take the total - the amount of guys
19,100 - 11460 = 7640
40% is female = 7,640
Answer:
45%
40 yellow chips
Step-by-step explanation:
Total chips: 9 + 11 = 20
P(Male) = 9/20 × 100 = 45%
60% of 100
60/100 × 100
60 red
100 - 60 = 40 yellow chips

Find The surface area of the pyramid
Answer:
85 ft^2
Step-by-step explanation:
Let us calculate the area of the triangles and the base.
For the triangles, we can use the area formula and get 5 • 3 which is 15. Since there are 4, we multiply it by 4 and get 60.
For the base, we have 5 • 5, which is 25. Adding it together, we get 85.
If you are stuck on how to find surface area, all you have to do is find the area of each side and add.

Option A is to be paid one cent on the first day of the month, with your wages doubling each day (2 cents on day 2, 4 cents on day 3, 8 cents on day 4, etc.) for the rest of this 30 day month. Option B is to be paid $1 on the first day of the month, with your wages increasing $100 each day ($101 on day 2, $201 on day 3, $301 on day 4, etc.). Which option will give you more money by the end of the month? Make sure to support your answer.
Answer:
Option B.
Step-by-step explanation:

The first option (A) will give you more money than option (B).
What are the geometrical progression series and arithmetic progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
Given that
Case A). Doubling each day
1 + 2+ 4 + 8 + 16 .... it is form a GP series with common ratio (r) 4/2 = 2
Number of terms (n)
Sum = 30( [tex]2^{30}[/tex] - 1)/(2 - 1) = $2147483464.
Case B). Adding $100 each day
1 + (101 + 201 + 301 ....) it is form a ap series with common difference d = 201 - 101 = 100.
Number of terms = 29
Sum = 1 + 29/2 + [ 2 (101) + 28(100)] = $43530
Hence it is clear that case (A) will give you more money.

Answer:
[tex]y=\frac{-5}{2}x+1.5[/tex]
Step-by-step explanation:
Well the equation we have [tex]y-4=\frac{-5}{2}(x-2)[/tex] is in slope-point form so we have to transfer it to slope intercept look at the first image below to see how I got [tex]y=\frac{-5}{2}x+9[/tex].
So we know that line T which is parallel to line S crosses through point (-1,4)
and we know that the slope stays the same and that its the y intercept has to change so the answer is [tex]y=\frac{-5}{2}x+1.5[/tex]. Look at the image second below.
Every minute 2.5 gallons of water flows from the shower a family of four people showers for an average five minutes per person every morning how many gallons of water does a family use for showering every morning
Answer:
number of gallons of water the family will use every morning = 50 gallons
Step-by-step explanation:
Every minutes 2.5 gallons of water flows from the shower . The amount of water disperse by the shower for every 1 minutes is 2.5 gallons. The family using the shower are 4 in numbers . And each of them spend on average of 5 minutes showering .
Let us find how many gallons of water will flow for 5 minutes since family member spent an average of 5 minutes bathing every morning/. Therefore,
2.5 gallons = 1 minutes
? gallons = 5 minutes
cross multiply
number of gallons of water each family member uses every morning = 2.5 × 5 = 12.5 gallons
They are 4 family members in number since each person uses 12.5 gallons of water , 4 of them will use 4 × 12.5 = 50 gallons
In triangle △JKL, ∠JKL is right angle, and KM is an altitude. JL=25 and JM=5, find KM.
HELP ME PLEASE!!!!!!
Answer:
KM = 15
Step-by-step explanation:
From the diagram, ΔJKL and ΔJKM are similar to each other because they share the same angle J and they are both right angle triangle. Therefore they are similar by AA property.
Since JL=25 and JM=5, JM = JL + JM= 25 + 5 = 30
Since ΔJKL and ΔJKM are similar to each other, therefore:
[tex]\frac{JK}{JL}=\frac{JM}{JK}\\ Substituting:\\\frac{JK}{30}=\frac{5}{JK}\\JK^2=150\\JK=\sqrt{150}\\ \\From\ hypotenuse:\\JK^2=JM^2+KM^2\\Substituting:\\(\sqrt{150} )^2=5^2+KM^2\\150=25+KM^2\\KM^2=150-25=125\\KM=\sqrt{125}\\ KM=15[/tex]

Which graph represents a line with a slope of and a y-intercept equal to that of the line y = x – 2? A coordinate plane with a line starting at (negative 2, negative 4), passing through (0, negative 2) and (2, 1). A coordinate plane with a line passing through (negative 3, 0) and (0, 2). A coordinate plane with a line passing through (0, 2) and (2, negative 1). A coordinate plane with a line passing through (negative 3, 0) and (0, negative 2).
The slope of a line is the average rate of change of the line.
The graph that represents [tex]\mathbf{y = x - 2}[/tex] is graph (a)
The line equation is given as:
[tex]\mathbf{y = x - 2}[/tex]
To do this, we simply test the options until we get the correct graph
(a) Line that passes through (-2,-4) and (0,-2)
This means that:
[tex]\mathbf{(x_1,y_1) = (-2,-4)}[/tex]
[tex]\mathbf{(x_2,y_2) = (0,-2)}[/tex]
Substitute values for x1 and y1 in [tex]\mathbf{y = x - 2}[/tex]
[tex]\mathbf{-4 = -2 - 2}[/tex]
[tex]\mathbf{-4 = -4}[/tex]
This point is true for [tex]\mathbf{y = x - 2}[/tex]
Substitute values for x2 and y2 in [tex]\mathbf{y = x - 2}[/tex]
[tex]\mathbf{-2 = 0 - 2}[/tex]
[tex]\mathbf{-2 = - 2}[/tex]
This point is also true for [tex]\mathbf{y = x - 2}[/tex]
Hence, the graph that represents [tex]\mathbf{y = x - 2}[/tex] is graph (a)
See attachment for the graph of [tex]\mathbf{y = x - 2}[/tex]

please help ! Find all the missing angel measures in angel 1,4,7,10,13 the picture is attached above please help !! It’s for geometry (:
Answer: ∠1 = 52°, ∠4 = 40°, ∠7 = 100°, ∠10 = 49°, ∠13 = 65°
Step-by-step explanation:
There are three formulas you need to find the angles. Each formula is based on where the vertex lies.
On the circle: Measure of the angle = (1/2) the arc (Images 1-3)
∠4 = (1/2)°80 ∠10 = (1/2)(18° + 80°) ∠13 = (1/2)130°
= 40° = (1/2)98° = 65°
= 49°
Inside the circle: (1/2) Sum of the Big arc and Little Arc (Image 4)
∠7 = (1/2) (130° + 70°)
= (1/2)200°
= 100°
Outside the circle: (1/2) Difference of Big arc and Little Arc (Image 5)
∠1 = (1/2)[(62° + 130°) - (70° + 18°)]
= (1/2) (192° - 88°)
= (1/2)104°
= 52°
I can only add 5 attachments. If you want to see image 6 (which contains the measures for all of the angles), you will need to ask the question again. Sorry!

a) (Triangle)ABC, given that AB = 16 cm, BC = 63 cm and
AC = 65 cm how do we find if it is a right angled
Answer:
Δ ABC is right angled
Step-by-step explanation:
If the triangle is right then the longest side squared will equal the sum of the squares on the other 2 sides.
longest side = 65, then
65² = 4225
16² + 63² = 256 + 3969 = 4225
Since 65² = 16² + 63² then Δ ABC is right
Answer:
We can know if it is a right angled triangle by using the Pythagoras theorem ( a²+b²=c²)
Step-by-step explanation:
To identify, we can take the largest length of the triangle as hypotanuse( that is, AC:65) And the rest as base and perpendicular ( 63 and 16 cm)
By applying Pythagoras theorem,
AB²+BC²= AC² ; (63)²+(16)²= (65)²
63² is 3969, 16² is 256… 65² is 4225.
Now, if 63²+16²:65²… then the triangle mentioned is a right angled triangle.
3969+256=4225
LHS = RHS, So, triangle ABC is a right angled triangle as it satisfies the condition of Pythagoras theorem.

Cylinder a has a radius 2 cm and contains water to a height of 10cm cylinder b has a radius 5cm and is empty. Some of the water is poured from cylinder a to b the height is now the same
Answer:
h = 1.38 cm
Step-by-step explanation:
The question is at what value is the height of both cylinders the same:
The area of the circular base on each cylinder is:
[tex]Area=\pi r^2\\A=4\pi \ cm^2\\B=25\pi \ cm^2[/tex]
The initial volume in cylinder A is:
[tex]V=4\pi *10\\V=40\pi\ cm^3[/tex]
We have that Va + Vb = 40π. The height of water in each cylinder as a function of volume is:
[tex]h_A=\frac{V_a}{4\pi}\\h_B=\frac{V_b}{25\pi}[/tex]
If both heights are the same:
[tex]\frac{V_a}{4\pi}=\frac{V_b}{25\pi}\\V_b=\frac{25}{4}V_a \\V_a+V_b=40\pi\\V_a+\frac{25}{4}V_a=40\pi\\V_a=5.5172\pi\ cm^3[/tex]
The height 'h' is:
[tex]h=\frac{5.5172\pi}{4\pi}\\ h=1.38\ cm[/tex]
