David has a rectangle and a right triangle.
The length of the rectangle is 5 more than its width, w.
The length of the shorter leg of the triangle is equal to the rectangle's
width.
The length of the longer leg of the triangle is twice the length of the
rectangle.
Which function, f(w), represents the combined area of the rectangle and the
triangle?
A f(w) = 2w2 + 10w
B. f(w) = 3w2 + 15w
С f(w) = W2 + 10w + 25

of Tank A, which measures 80 cm by 30 cm by 50 cm, is filled with water
and of Tank is nilled with water. The ratio of the volume of water in
Tank A to that in Tank Bis 5. 2. How much more water is needed to up
Tarik ?
Answer:
72L
Step-by-step explanation:
I'm assuming Tank A and Tank B have the same volume. The question has many typos and is a bit hard to understand
Tank A Volume
V = l × w × h
= 80 × 30 × 50
= 120,000cm²
Tank A Capacity = 120,000ml
=120L
The Question states that Tank A is filled to capacity which means Tank A currently holds 120L of water
Tank A:Tank B = 5:2 = 120:x
120 ÷ 5 = 24L
24 × 7 = 168
168 × [tex]\frac{2}{7}[/tex] = 48
This means Tank B currently holds 48L of water
120 - 48 = 72L
∴72 more litres of water is needed to fill Tank B

The graph shows the distance a bicyclist traveled from a starting point in 10-second increments. Which of these is closest to the average speed of the bicyclist during 30 seconds of motion?
A. 0.3m/s
B. 3m/s
C. 10m/s
D. 30 m/s
PLEASE HELP QUICK!
Answer: 3m/s
Step-by-step explanation:
the formula for speed is distance divided by time, the question tells us the time is referring to the first 30 seconds, so just divide the distance by time (the answers you’d get are 3, 3, 1) so 3 m/s is closest to the average speed
The average speed of the bicyclist during 30 seconds of motion is mathematically given as
v'=3m/s
What is the average speed of the bicyclist during 30 seconds of motion?Question Parameter(s):
During 30 seconds of motion
Generally, the equation for the speed is mathematically given as
v=d/t
Therefore
v'=(30/10+60/20+30/30)3
v'=3m/s
In conclusion, Average speed
v'=3m/s

Select all the statements about the situation that are true. Elena makes more money for making 10 calls than Diego makes for washing 10 windows. Diego makes more money for washing each window than Elena makes for making each call. Elena makes the same amount of money for 20 calls as Diego makes for 18 windows. Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls. The equation y = 910x, where y is number of dollars and x is number of windows, represents Diego's situation. The equation y = x, where y is number of dollars and x is number of calls, represents Elena's situation.
Answer:
B, C, E
Step-by-step explanation:
Elena’s aunt pays her $1 for each call she makes to let people know about her aunt’s new business. The table shows how much money Diego receives for washing windows for his neighbors.
Select all the statements about the situation that are true.
A. Elena makes more money for making 10 calls than Diego makes for washing 10 windows.
Elena:
$1 = 1 call
$10 = 10 calls
Diego:
27 windows = $30
10 windows = $x
Cross product
27*x = 30*10
27x = 300
x = 300/27
x = $11.11
Statement A not true
B. Diego makes more money for washing each window than Elena makes for making each call.
Diego:
10 windows = $11.11
Each window = $11.11/10
= $1.11
Statement B is true
C. Elena makes the same amount of money for 20 calls as Diego makes for 18 windows
Elena:
20 calls = $20
Diego:
18 windows = 18 × $1.11
= $19.98
Approximately $20 to the nearest whole dollar
Statement C is true
D. Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls.
Diego
35 × $1.11 = $38.85
Approximately $39
Elena:
40 calls = $40
Statement D is not true
E. The equation y = x, where y is the number of dollars and x is the number of calls, represents Elena’s situation.
Statement E is true

Lines a and b are parallel. What is the measure of angle s?
S= Enter your answer in the box.
Answer:
Step-by-step explanation:
t = 158 Corresponding angles
t + s = 180 They are supplementary angles
158 + s = 180 Subtract 158 from both sides
s = 180 - 158
s = 22
As a note, all angles in this situation are either 158 or 22.

(a) 1.2 kg
(b) 2.4 kg
(c) 3.8 kg
(d) 3 kg
I also need explanation
(b) 2.4kg
Known15 books = 6kg
Question6 books = ?kg
Way to do#Find the weight of 1books first
6kg : 15 = 0.4kg
#After that you times 6 to find the weight of 6 books
0.4kg × 6 = 2.4kg
#So the weight of 6 books is 2.4kg
A silo has a radius of 10 meters, like the one shown, and is filled from top to bottom with rice. If rice sells for $75 a cubic meter, what is the total value of rice in this silo?
Answer:
$1500
Step-by-step explanation:
Since the radius of the silo is 10 meters, then the total length of the silo is 20 meters. So now we multiply 75 by 20
75 x 20 = 1500
So the value of the rice in the silo is $1500

5^9.969
Answer:
A.
Step-by-step explanation:
got it right on test
The provided expression is equivalent to the expression mentioned in option (A), and option (A) is correct.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
We have:
[tex]= 5^{9.969}[/tex]
We can write it as:
[tex]= 5^{\dfrac{9969}{1000}}[/tex]
or
[tex]= 5^{\dfrac{9000+900+60+9}{1000}}[/tex]
[tex]= 5^{{9}} \ 5^{\dfrac{9}{10}} \ 5^{\dfrac{6}{100}} \ 5^{\dfrac{9}{1000}}[/tex]

If k/3 – 9 = 12, what is the value of k?
Answer:
k = 63
Step-by-step explanation:
k/3 - 9 = 12
isolate variable + 9 both sides
k/3 = 21
multiply both sides by three, therefore
k = 63
check:
63/3 - 9 = 12
21 - 9 =12
12 = 12
hope this helps!
The solution of the linear equation k/3 – 9 = 12 will be 63 which is the value of the variable k.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given below.
k/3 – 9 = 12
Add 9 on both sides, then the equation will be
k/3 = 12 + 9
k/3 = 21
Multiply the equation by 3 on both sides, then the value of the variable k will be
k = 21 x 3
k = 63
The solution of the linear equation k/3 – 9 = 12 will be 63 which is the value of the variable k.
