Answer:
40% of the student is 160
30% of the students is 120
10% of the students is 40
the remain is ___
160 + 120 + 40= 320
400 -320 = 80
meaning 160 students passes only math (40%). 120 students passed on science (30%). 40 students fail both subjects (10%) and 80 students passes both subjects (20%)
Ms. Buback is competing in a race in which she both runs and rides a bike. She runs 5 kilometers in 0.5 hours and rides her bike 20 kilometers in 0.8 hours. At the rate given, how many kilometers can she bike in one hour?
Answer:
25.02 km/h
Step-by-step explanation:
60 min × 0.8 = 48 min
20 km÷48 = 0.417 km/min
0.417 × 60 = 25.02 km
chuck was chopping wood.when he was done he had 25 kg of firewood what was most likely the weight of the wood before he chopped it
Answer:
The weight of the wood before he chopped it is 245 N
Step-by-step explanation:
The law of conservation of mass states that for a given isolated system, mass (or matter) can not be created neither can it be destroyed, but it can be transformed into different forms
Therefore, whereby all the wood Chuck chops is taken as firewood, (wood which is dry is about 100% consumable as firewood) the mass of the wool before he chopped the wood = The mass of the firewood he had after chopping the wood = 25 kg
Weight = Mass × The acceleration due to gravity, g
g = Constant = 9.8 m/s²
The weight of the wood before he chopped it = 25 kg × 98 m/s² = 245 N.
Answer:
as much as it wants

#2: Given the geometric sequence 200, 100, 50, 25... (This one is tricky)
Write the explicit formula.
• Determine the 15th term of the sequence?
Answer:
see explanation
Step-by-step explanation:
The explicit formula for a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 200 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{100}{200}[/tex] = [tex]\frac{1}{2}[/tex] , then
[tex]a_{n}[/tex] = 200 [tex](\frac{1}{2}) ^{n-1}[/tex] ← explicit formula
The 15 th term is then
a₁₅ = 200 × [tex](\frac{1}{2}) ^{14}[/tex]
= 200 × [tex]\frac{1}{16384}[/tex]
= [tex]\frac{200}{16384}[/tex] ← divide numerator/ denominator by 8
= [tex]\frac{25}{2048}[/tex]

if ordered pair (k, -3) lies on the graph of 5x - 2y = -24 then what is the value of k
Answer:
given,
(x y)= (k -3)
so ,
5x- 2y= -24
or, 5k +6 =-24
or,5k =-24 - 6
or,5k= -30
therefore,
k=-6
A shirt is priced at $12. What is the price after a 15% discount and 7% sales tax?

Answer:
10) 15,794
11) 20,306
Step-by-step explanation:
10) Sin(33) = x÷29
Multiply with 29 on both sides.
x = Sin(33) × 29 = 15,794
11) Tan(55) = 29÷x
Multiply with x on both sides.
xTan(55) = 29
Divide with Tan(55) on both sides.
x = 29 ÷ Tan(55) = 20,306
Ms. Semuskie is buying bagels for her family. How many bagels can she buy for 50$

The surface area of a cube is represented by the expression below, where s is the side length of the cube. Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.
Answer:
486 centimeters³
Step-by-step explanation:
Surface area of a cube = 6s²
Where,
s = side length
Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.
s = 9 centimeters
Surface area of a cube = 6s²
= 6 × 9²
= 6 × 81
= 486 centimeters³
Surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters 486 centimeters³

Solve for X-B(5,0.85), for x = 3.
Answer:
Solve for X-B(5,0.85), for x = 3.*25*
delete my question if it's wrong
The value of the expression is,
X = 0.138
We have to give that,
An expression is,
⇒ X ~ B (5, 0.85)
for, x = 3
Now, simplify the expression for x = 3 as,
X = ⁵C₃ (0.85)³ (1 - 0.85)³⁻¹
X = (5!/3!2!) (0.85)³ (1 - 0.85)²
X = 10 × (0.85)³ (0.15)²
X = 0.138
Hence, The value of the expression is,
X = 0.138

Therefore, the correct option is A.
In the year 2010, a person bought a new car for $26000. For each consecutive year after that, the value of the car depreciated by 10%. How much would the car be worth in the year 2014, to the nearest hundred dollars?
Answer:
$17,100
Step-by-step explanation:
Set up an equation where y is the worth of the car and t is the number of years since 2010:
y = 26000(0.9)^t
Plug in 4 as t, since it is asking about 2014:
y = 26000(0.9)^t
y = 26000(0.9)^4
y = 17058.6
Round to the nearest hundred dollars:
17058.6
= 17,100
So, the car will be worth approximately $17,100

Here's a graph of a linear function. write the equation that describes that function.
Answer:
y = 1/4x + 5
Step-by-step explanation:
Here, we want to write the equation of the function
Generally we can have the equation of a straight line as;
y = mx + b
m is slope, b is the y-intercept
From the graph we have the y-intercept as 5
To get the slope, we select any two points and apply the slope formula
Let us have the points;
(8,7) and (4,6)
the slope will be;
m = (y2-y1)/(x2-x1) = (6-7)/(4-8) = 1/4
So the equation of the line is;
y = 1/4x + 5
