Answer:
7/18
Step-by-step explanation:
If 1/3 of the counters are green that means that 60 counters are 1/3 of the total number of counters. We can multiply 60 by 3 to find the total number (3/3) of counters: 60 × 3 = 180
Next, we can find out how many counters are blue and green by subtracting 60 from 180: 180 - 60 = 120
If there are 20 more red counters than blue counters, we can write this algebraically as x + (x + 20) = 120. x + 20 is the number of red counters and x is the number of blue counters
To find x, simplify the equation:
2x + 20 = 120
2x = 100
x = 50
There are fifty blue counters, therefore there are 70 red counters. The probability of picking a red counter is 70/180 or 7/18.
Hope this helps!
Find the area of the following figure
Answer:
A = 280 ft²
Step-by-step explanation:
the figure is composed of a rectangle and a triangle.
area of rectangle = 20 × 10 = 200 ft²
area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is base and h the height )
b = 20 and h = 18 - 10 = 8 , then
area = [tex]\frac{1}{2}[/tex] × 20 × 8 = 10 × 8 = 80 ft²
total area A = 200 + 80 = 280 ft²
12. In PQR if mP is 14 less than five times x, mQ is five less than x, and mR is nine less
than twice x, find x and the measure of each angle.
Answer:
Step-by-step explanation:
mP=5x-14
mQ=x-5
mR=2x-9
we know that all the angles in a triangle= 180
that means (5x-14)+(x-5)+(2x-9)=180
5x-14+x-5+2x-9=180 we add the variables and the numbers
8x=180+28
8x=108
x=26
mP=130-14=116
mQ=26-5=21
mR=43

Victoria bought 14 chicken wings for 19.60. If victoria spent 23.80, how many chicken wings did she buy
Answer:
17 wings
Step-by-step explanation:
Money/How Many
19.60/14=1.4
1.4 is the unit rate, so we divide 23.80/1.4 to find how many chicken wings

Which quadratic function is represented by the table? f(x) = 3x2 2x – 5 f(x) = 3x2 – 2x 5 f(x) = 2x2 3x – 5 f(x) = 2x2 – 2x 5
For the values of x, the quadratic function f(x) = 3x² – 2x + 5 is satisfied. Then the correct option is B.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
At x = –2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–2)² – 2(–2) + 5
f(x) = 12 + 4 + 5
f(x) = 21
At x = –1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–1)² – 2(–1) + 5
f(x) = 3 + 2 + 5
f(x) = 10
At x = 0, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(0)² – 2(0) + 5
f(x) = 0 + 0 + 5
f(x) = 5
At x = 1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(1)² – 2(1) + 5
f(x) = 3 – 2 + 5
f(x) = 6
At x = 2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(2)² – 2(2) + 5
f(x) = 12 – 4 + 5
f(x) = 13

jon works in the shipping department at crunchy cereal. to find out how many cereal boxes fit in one shipping container, jon divides the volume of the container by the volume of one cereal box. using the diagram and jon's method, determine how many cereal boxes can be packed in the container.
a) 12 boxes
b) 18 boxes
c) 20 boxes
d) 24 boxes
To know the number of boxes that can fit divide the volume of the shipping container by the volume of one cereal box.
How to calculate the number of boxes that can fit in the shipping container?To do this use the formula;
volume of the shipping container/ volume of a box of cereal = number of cereal boxes that can fit.How to calculate the volume of the container and the volume of the cereal boxes?Since both the container and the boxes likely have a defined rectangular shape you can use this formula:
length x width x heightFor example:
Dimensions of the container:
120 cm x 100 cm x 100 cm = 1200000 cubic centimeters
Dimensions of the boxes:
30 cm x 30 cm x 10 cm = 9000 cubic centimeters.
1200000 cc / 9000 cc = 133 boxes.

A right triangle has legs of length 136 cm and 119 cm. What is the length of the hypotenuse of the right triangle? Enter the answer, rounded to the nearest tenth, in the box.
Answer:
Hypotenuse= 180.7 cm
Step-by-step explanation:
Using Pythagoras' theorem:
a^2+b^2=c^2 (let c= Hypotenuse "H")
(136)^2 + (119)^2 = H^2
18496+14161 =H^2
H^2= 32657
Taking square root on both sides

Answer:
Y=6X
Step-by-step explanation:
Step by step explanation is on the pic above
Answer:
y = 6x
Step-by-step explanation:
We can find the relationship by looking at each value for X and Y and finding which number makes the equation true
The first equations says Y = 3 when X = 0.5, Lets put this into an equation
[tex]3= ?*0.5[/tex]
The only number that would make this equation true is 6
[tex]3=0.5*6[/tex]
Lets try another, The Third equation says that Y = 9 when X = 1.5
[tex]9 = 1.5*?[/tex]
Again, the only number that works is 6
[tex]9=1.5*6[/tex]
Hence the equation for this table is [tex]Y=6x[/tex]

Using the net below, find the surface area of the triangular prism.
Answer:
Hi, there! The total surface area of that prism is 118 cm^2.
Step-by-step explanation:
The three rectangles on the side are called the lateral area, and they add up to 98(I'm assuming you know how to find the area of a 2d shape), and as for the triangles on the sides, you can just use the formula which is [tex]b*h/2[/tex].
Hope this helps :)
Answer:
118 cm²
Step-by-step explanation:
Area of rectangle = l x b
= 7 x 5 = 35cm²
=4 x 7 = 28cm²
Add the area of the three rectangles = 35+35+28
=98cm²
Area of triangle = 1/2 x b x h
= 1/2 x 4 x 5
= 10 + 10 = 20
Therefore, area of the prism = 118cm²
