Which of the following shapes are quadrilaterals?
please help asap I'll make brainliest
Explanation:
A quadrilateral has four sides, and each side is a straight line.
Quad = 4
Lateral = side
This means we go for choices A and C.
Choice B is ruled out because of the curved side on the right.
Choice D is ruled out because it has 5 sides instead of 4.
Julian is working two summer jobs, making $8 per hour washing cars and making
$13 per hour tutoring. In a given week, he can work a maximum of 13 total hours and
must earn no less than $130. If a represents the number of hours washing cars and y
represents the number of hours tutoring, write and solve a system of inequalities
graphically and determine one possible solution.
Answer:
Jacob should work minimum of 14 hours washings cars to meet his requirement.
Step-by-step explanation:
Let the number of hours of washing cars be 'x'.
Let the number of hours of landscaping be 'y'.
Given:
Cost for Per hour for washing cars = $10
Cost for per hour Landscaping = $8
Total number of hours of working
Amount to be earned this weekend
So we can say that;
Also,
Amount to be earned this weekend should be greater than or equal to sum of Cost for Per hour for washing cars multiplied by number of hours of washing cars and Cost for per hour Landscaping multiplied by number of hours of landscaping.
framing in equation form we get;
Now Number of hours he worked for landscaping
So we get;
Subtracting both side by 32 we get;
Dividing both side by 10.
Hence Jacob should work minimum of 14 hours washings cars to meet his requirement.

Answer:
[tex]f^{-1}[/tex] (59) = 20
Step-by-step explanation:
[tex]f^{-1}[/tex] (x) is the inverse of f(x)
to find the inverse function, let f(x) = y and rearrange to make x the subject.
y = 3x - 1 ( add 1 to both sides )
y + 1 = 3x ( divide both sides by 3 )
[tex]\frac{y+1}{3}[/tex] = x
change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+1}{3}[/tex] , then
[tex]f^{-1}[/tex] (59) = [tex]\frac{59+1}{3}[/tex] = [tex]\frac{60}{3}[/tex] = 20
For each 15mm of coloured fabric Gavyn uses to make his curtains he also uses 2 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form
Answer:
Step-by-step explanation:
2cm = 2 * 10 mm
2 cm = 20 mm
for every 15 mm of colored fabric, Gavyn uses 20 cm of white fabric.
The ratio is expressed as white fabric to colored fabric.
Answer: Ratio white to colored = 20 / 15 = 4 / 3

50 PTS!!A right triangle has a leg measuring 16in. And 28in.
What is the length of the hypotenuse?
Round your answer to the nearest tenth.
1)23.0 in.
2)32.2 in.
3)44.0 in.
4)1040.0 in
Answer:
2) 32.2 in (nearest tenth)
Step-by-step explanation:
Pythagoras’ Theorem
[tex]\sf a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = 16 inb = 28 inc = hypotenuseSubstituting these values into the formula and solving for c:
[tex]\implies \sf 16^2+28^2=c^2[/tex]
[tex]\implies \sf 256+784=c^2[/tex]
[tex]\implies \sf c^2=1040[/tex]
[tex]\implies \sf c=\pm\sqrt{1040}[/tex]
[tex]\implies \sf c=\pm 32.2\:in\:(nearest\:tenth)[/tex]
As distance is positive, c = 32.2 in (nearest tenth)
Step-by-step explanation :
Here, A right angled triangle is given with the measure of two sides and we are to find the measure of the third side.
We'll find the measure of third side with the help of the Pythagorean theorem,
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}} \\ \\ [/tex]
Here,
The base (BC) is 16 inThe perpendicular (AB) is 28 inThe hypotenuse is AC.[tex] \: [/tex]
So, substituting the values in the formula we get :
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (AC {)}^{2}= (16) {}^{2} + (28 {)}^{2} }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad (AC {)}^{2}=256 + 784 }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad (AC {)}^{2}=1040 }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad AC = \sqrt{1040} }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\frak {\qquad AC = 32.24 }}} \\ \\[/tex]
Therefore,
The length of the hypotenuse (AC) is 32.2 in (Rounded to nearest tenth)he quadratic function h(t)=-16.1t^2 + 150 models a balls height, in feet, over time, in seconds, after it is dropped from a 15 story building. From what height, in feet, was the ball dropped? AND After how many seconds, rounded to the nearest hundredth, did the ball hit the ground?
Answer:
The time it takes the ball to hit the ground is 3.05secs
step - by - step explanation:
In order to find height from where ball is dropped, you have to find height or h(t) when time or t is zero.So plug in t=0 into your quadratic equation:h(0) = -16.1(0^2) + 150h(0) = 0 +150h(0) = 150 ft is the height from where ball is dropped. When ball hits the ground, the height is zero. So plug in h(t) = 0 and solve for t.0 = -16.1t^2 + 15016.1 t^2 = 150t^2 = 150/16.1t = sqrt(150/16.1)t = ± 3.05Since time cannot be negative, your answer is positive solution i.e. t = 3.05

The value of the exponential equation is A = ( 1/343 ) = ( 1/7 )³
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( 1/7 ) x ( 1/7 ) x ( 1/7 ) be equation (1)
On simplifying the equation , we get
A = ( 1/7 )³
Now , on further simplification , we get
A = ( 1/343 )
And , the value of A = 0.002915
Hence , the exponential equation is A = ( 1/7)³

The group wants to travel from its current location on the map to the South Pole, and then directly back to base camp, passing through their current location. There are 5 people in the group and they expect to travel an average of 10 miles per day. Remember that each person needs 6000 calories per day. Based on your response to item 3, what is the minimum number of calories the group is expected to consume during the entire trip?
the answer to number 3 is 75 miiles
The minimum number of calories the group is expected to consume during the entire trip from current location to southpole and back to camp is 375 kilo calories.
What is Pythagoras theorem?Pythagoras theorem says that in a right angle triangle the square of hypotenuse side is equal to the sum of square of other two legs of right angle triangle.
There are total 5 miles in one block and current location to the South Pole there are 5 blocks on map. Thus, the total distance from current location to the South Pole is,
[tex]x=5\times5\\x=25\rm\; miles[/tex]
There are total 12 blocks from current location to the camp on map. Thus, the total distance from current location to the camp is,
[tex]y=12\times5\\y=60\rm\; miles[/tex]
The shortest distance from South Pole to camp is,
[tex]z=\sqrt{25^2+60^2}\\z=\sqrt{4225}\\z=65\rm\; miles[/tex]
Total distance group travel from if it wants to travel from its current location on the map to the South Pole, and then directly back to base camp, passing through their current location is,
[tex]n=65+60\\n=125\rm\; miles[/tex]
The group travel an average of 10 miles per day. Thus, number of days to cover distance,
[tex]\dfrac{125}{10}=12.5\rm\; days[/tex]
There are total 5 people in group and they consume each person needs 6000 calories per day. Thus, total calories,
[tex]C=12.5\times6000\times5\\C=375000 \rm\;C\\C=375 \rm\; kC[/tex]
Thus, the minimum number of calories the group is expected to consume during the entire trip from current location to southpole and back to camp is 375 kilo calories.
