Answer:
Yes he is Correct
Step-by-step explanation:
When multiply with numbers like 10,100,1000 ect or even like 20,200,2000 then you have to break it down. Since multiply by zero equals 0 anyways you will only have to focus on the number that is in front of it. And just and the zeros to the back of the number.
Answer:
Yes he is correct
Step-by-step explanation:
Whenever we are multiplying any number with 10 or multiples of ten we simply add the zeros to the end of that number.
For example:
134 x 10 = 1340
As you can see, to get the answer, you simply need to add 0 to the end of 134
Also 10 x 10 = 100
To get the answer we simply added zero to the end of ten which then give us 100
12 x 10= ? all you need to do is to add zero to the end of 12 which will give us 120
13 x 100 =? In this case, since the zeros are two, you will simply add two zeros to the end of 13 which will give you the answer 1300
So Marcel can find 52 times 10 by simply adding a 0 to the end of 52 to get 520 as the correct answer.
About how many feet of fencing are needed to enclose a rectangular garden with a 30 foot pond side and a 40 foot long diagonal
Answer:
140
Step-by-step explanation:
30+30=60
40+40=80
60+80=140
Answer: Hello there!
If you want to enclose a rectangular garden, then the feet of fencing that you need are equal to the perimeter of the rectangle, this is, the sum of all the sides of the rectangle.
We know that the rectangle has a 30ft pond side and a 40ft long diagonal.
this 40ft diagonal is the hypotenuse of a triangle rectangle where the cathetus is the sides of the rectangle; we know that one of the sides are of 30 ft, and we want to find the other:
Using the Pythagorean theorem; we know that:
[tex]40^{2} = 30^{2} + x^{2}[/tex]
where x is the length of the other side that we don't know yet.
[tex]x = \sqrt{40^{2} - 30^{2} } = 26.5ft[/tex]
Then your rectangle has a 30ft side, and a 26.5ft side (and has two of both)
Then the perimeter is:
30ft + 30ft + 26.5ft + 26.5ft = 113ft

3.7 ÷ 1.1 = ? Round to the nearest hundredth. A. 4.8 B. 0.297 C. 4.07 D. 3.36
The answer is D.
Hope this helps!
Answer:
D. 3.36
Step-by-step explanation:
Just by intuition, we can see that 3.7 / 1.1 will give a result somewhere around 3.3 (forget the decimal point, think 37 / 11). That automatically allows you to zoom in on the correct answer, based on the other choices.
But let's verify it too.
3.7 / 1.1 = 3.363636
They ask to round to the nearest hundredth, so 3.363636 becomes 3.36

A chemical company makes two brands of antifreeze. The first brand is 45% pure antifreeze and the second brand is 70% pure antifreeze. In order to obtain 150 gallons of a mixture that contains 55% pure antifreeze, how many gallons of each brand of antifreeze must be used?
First brand: ____ gallons
Second brand: ___ gallons
Answer:
First brand(45%): 90 gallons
Second brand(70%): 60 gallons
Step-by-step explanation:
"The first brand is 45% pure antifreeze and the second brand is 70% pure antifreeze. In order to obtain 150 gallons of a mixture that contains 55% pure antifreeze, how many gallons of each brand of antifreeze must be used?
First brand: ____ gallons
Second brand: ___ gallons"
We know that 70 is 15 away from 55, and 45 is 10 away, making this a 10: 15 ratio of 70 to 45 (because the 70 can only counteract the 45 by 10, and the 45 can only counteract the 70 by 15 unless they want to overshoot the 55% average ).
This means that .4*150 is 70% and .6*150 is 45%
This means there is First brand: 90 gallons
Second brand: 60 gallons

3n-7/6=2n+5/3 n=what
[tex]\frac{3n-7}{6}=\frac{2n+5}{3}[/tex] Multiply 3 and 6 on both sides to get rid of the fraction (or cross multiply)
[tex]\frac{3n-7}{6}(3)=\frac{2n+5}{3} (3)[/tex]
[tex]\frac{3n-7}{6}(3)(6)=(2n+5)(6)[/tex]
3(3n - 7) = 6(2n + 5) Distribute/multiply 3 into 3n-7, and 6 into 2n+5
(3)3n - (3)7 = (6)2n + (6)5
9n - 21 = 12n + 30 Subtract 9n on both sides
-21 = 3n + 30 Subtract 30 on both sides
-51 = 3n Divide 3 on both sides

Step 6 :
When a fraction equals zero :
6.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
6n-17
————— • 6 = 0 • 6
6
Now, on the left hand side, the 6 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
6n-17 = 0
Solving a Single Variable Equation :
6.2 Solve : 6n-17 = 0
Add 17 to both sides of the equation :
6n = 17
Divide both sides of the equation by 6:
n = 17/6 = 2.833
One solution was found :
n = 17/6 = 2.833
I haven’t done area in a while and now we have to do with algebra, can anyone please help me with this? Thanks!
Answer: The area of the triangle is:
____________________________________________________
→ " (4x² + 6x) cm³ " .
____________________________________________________
Step-by-step explanation:
____________________________________________________
The formula for the "Area, "A" ; of a triangle is:
A = (1/2) * (baselength) * (perpendicular height) ;
→ that is:
→ A = (1/2) * b * h ;
____________________________________________________
The Area, "A" ; should be in "cubic units" ; in our case, "cubic centimeters" ;
or; " cm³ " .
____________________________________________________
Given: baselength: "b" = " 4x " ;
perpendicular height: " h = (2x + 3) " ;
____________________________________________________
Plug in these values into the equation/formula:
A = (1/2) * b * h ;
→ A = (1/2) * (4x) * (2x + 3) ;
→ (1/2) * 4x = 2x ;
→ A = 2x (2x + 3) cm³
____________________________________________________
→ 2x (2x + 3) = ?
____________________________________________________
Note the "distributive property" of multiplication:
→ a(b + c) = ab + ac .
____________________________________________________
As such:
→ 2x (2x + 3) = 2x(2x) + (2x)(3) ;
= 4x² + 6x ; ____________________________________________________
The area of the triangle is: " (4x² + 6x) cm³ " .

Convert z = 8cos72° + 8isin72° from polar form to rectangular form.
Answer:
The rectangular form of z = 8 cos72° + 8 sin72° is z = (2.5 , 7.6)
Step-by-step explanation:
* Lets revise how to change from polar form to rectangular form
- Cartesian Coordinates (x , y) and Polar Coordinates (r , θ)
- Where x = r cosФ , y = r sinФ
* To convert from Polar Coordinates (r , θ) to Cartesian Coordinates (x , y)
# x = r × cos( θ )
# y = r × sin( θ )
* In the problem
∵ z = 8 cos72° + 8 sin72°
∴ r = 8
∴ Ф = 72°
∵ x = r cosФ
∴ x = 8 cos72° = 2.5
∵ y = r cosФ
∴ y = 8 sin72° = 7.6
* The rectangular form of z = 8 cos72° + 8 sin72° is z = (2.5 , 7.6)
A basketball coach claims that the team's players commit, on average, no more than 10 fouls per game. Let µ represent the team's average number of fouls per game. Another coach thinks that these players create more fouls.
What is the null hypothesis, H0, for this situation?
(B) u ≤ 10
What is the alternative hypothesis, Ha, for this situation?
(B) u > 10
What type of significance test should be used for this situation?
A right-tailed test
These are the correct answers but I don't know the explanations for them someone help me out
Answer:
H0: u ≤ 10
Ha: u > 10
A right-tailed test
Step-by-step explanation:
In hypothesis testing there are two types of hypotheses;
The null hypothesis, H0 and the alternative hypothesis, Ha. The null hypothesis is the hypothesis of no difference and as such it always has an equality sign;
=, ≤, ≥
On the other hand the alternative hypothesis complements the null hypothesis meaning that if the null hypothesis is rejected then we take the alternative hypothesis to be true.
In order to identify the null and alternative hypothesis we look out for specific key words that will provide us with information on the type of inequality sign. In this scenario, the coach claims that the average number of fouls committed per game is no more than 10. Since µ represents the team's average number of fouls per game, this statement can be written in mathematical symbols as;
u ≤ 10, that is u is no more than 10; average number of fouls committed per game is no more than 10.
This statement will be our null hypothesis since it contains an equality sign.
H0: u ≤ 10
The complement of this statement will enable us deduce the alternative hypothesis. The complement of this statement can be found in the claim of the second coach who thinks that these players create more fouls, to be specific more than 10 fouls. In mathematical notation this claim can be written as;
u > 10, more than 10 fouls.
This statement will be our alternative hypothesis since it complements the null hypothesis;
Ha: u > 10
The type of significance test to be carried out in hypothesis testing emanates from the inequality sign of the alternative hypothesis. The following are the key points to note, if the alternative hypothesis contains;
≠, then this automatically becomes a two tailed test
<, then this automatically becomes a left tailed test since the inequality sign is pointing towards the left.
>, then this automatically becomes a right tailed test since the inequality sign is pointing towards the right.
Our alternative hypothesis contains >, hence this will be a right-tailed test .

Find the slope and y-intercept of the line. y=-x+7
Answer:
slope = - 1, y- intercept = 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x + 7 ← is in slope- intercept form
with slope m = - 1 and y- intercept c = 7
The slope of the line y = -x + 7 is -1, and the y-intercept is 7.
To determine the slope and y-intercept of the line given by the equation y = -x + 7, we first recognize that it is in slope-intercept form, which is y = mx + b.
Identify the slope (m): In the equation y = -x + 7, the coefficient of x is -1. Thus, the slope of the line is -1.
Identify the y-intercept (b): The constant term in the equation is 7. Thus, the y-intercept is 7, meaning the line intersects the y-axis at the point (0, 7).
The slope of the line y = -x + 7 is -1, and the y-intercept is 7.
One half the difference of the cube of a number, x, and three
Answer:
(1/2)(x³ - 3)
Step-by-step explanation:
That would be (1/2)(x³ - 3).
The expression ' one-half difference of a number cubed and one' is written as [tex]\frac{1}{2} (x^3 - 1)[/tex].
Let the number be [tex]x[/tex].
The cube of the number is [tex]x^3[/tex].
Difference of the cube of the number with [tex]1[/tex] is [tex]x^3 - 1[/tex].
Now, one-half difference of a number cubed and one is represent as,
[tex]\frac{1}{2} (x^3 - 1)[/tex].
So, the expression ' one-half difference of a number cubed and one' is written as [tex]\frac{1}{2} (x^3 - 1)[/tex].

What’s the future value of a $1,000 investment compounded at 8% semiannually for five years?
Answer:
$1480.24
Step-by-step explanation:
This will be solved by the formula:
[tex]FV=I(1+r)^t[/tex]
Where
FV is the future value (what we are looking for)
I is the initial amount (which is $1000)
r is the rate of interest per period (8% is annual interest, but the period is SEMI-ANNUAL, that's 6 months, half of yearly. So r would be half of 8%, which is 4% or r = 0.04)
t is the times compounding occurs in the whole time (The whole time period is 5 years, but compounding occurs semi-annually, so 5*2 = 10 times. Thus, t = 10)
plugging the info into the formula we will get our answer.
[tex]FV=I(1+r)^t\\FV=1000(1+0.04)^{10}\\FV=1000(1.04)^{10}\\FV=1480.24[/tex]
