Answer:
a = 44.1
Step-by-step explanation:
Do the addition in the parentheses first.
a / (3.15) = 14
Multiply both sides by (3.15) to isolate a.
3.15(a/3.15)=14(3.15)
a = 44.1

Which fraction and decimals forms match the long division problem?
Answer:
A
Step-by-step explanation:
the numerator always goes into the dividend, and in this case the dividend is 7, so 7/9 is correct rather than 9/7. and the decimal form is 0.7777777+ it is not 0.7 because the question keeps adding zeros when the whole number is supposed to be 7, not 7.000. hope that helps.

Answer:
a. = x > 3
b. = x < 2
c. = x > -5
d. = x > 10
Step-by-step explanation:
Solve means to find x.
a.
3x - 3 > 6
+3 each side
3x > 9
Divide by 3 each side
x > 3
b.
24x + 4 < 52
-4 each side
24x < 48
Divide by 24 each side
x < 2
c.
-2x - 2 < 8
+2 each side
-2x < 10
Divide by -2 each side (Causing the inequality sign to flip, dividing or multiplying by a negative causes it to.)
x > -5
d.
10x - 100 > 0
+100 each side
10x > 100
Divide by 10 each side
x > 10

A plant is 5cm tall and growing at a rate of 3cm a month. What is the right equation?
1. y= 5 - 3x
2. y=3x+5
3. y= 5x+3
Answer:
C. y=3x+5
Step-by-step explanation:
It is at a growing rate of 3cm a month.
x = centimeters a month
y = total amount
Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those surveyed, do not want a new mall. How many people did Annette survey?
We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.
We will find that the number of people that Annette survey is 480.
To get the solution:
Let's assume that she surveyed a total of X people.
Then we can write the equivalence:
100% = X
We know that the 37.5% is equivalent to 180 people, then we can write:
37.5% = 180
The two equations are:
100% = X
37.5% = 180
Now we can take the quotient between these two equations to get:
(100%/37.5%) = X/180
Solving for X we get:
(100%/37.5%)*180 = X = 480
So the total number of people surveyed is 480.
Answer:
480 people
180/X × 100 = 37.5%
180 × 100 = 37.5 × X
18000 ÷ 37.5 = 37.5 × x ÷ 37.5
480 people = x

7a + 50 = 247
Answer:
a = 28.14 (Estimated)
Step-by-step explanation:
7a + 50 = 247
=> 7a = 197
=> a = 28.1428571429 (Using Calculator)
=> a = 28.14 (Estimated)
Hoped this helped.
Answer:
a= 190
Step-by-step explanation:
7a+50=247
=7a = 247-50
= a = 197-7
= a = 190

Green is with C, Blue is with A, Orange is with D, Purple is with B
Step-by-step explanation:
Hi!
So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)
(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)
1(left)-7/1/4 is the same as 7/ .25. This is 28.
2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating
3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating
4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)
1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.
2(right) 1/4 x 7 is the same as .25*7. This is 1.75
3(right) 7*4 is 28.
4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533
Now, we can match.
Green is with C.
Blue is with A
Orange is with D
Purple is with B

Find the value of x in the isosceles triangle shown below
Answer:
x = 10
Step-by-step explanation:
if there 2 same triangle then they are right triangle
By using Pythagorean theorem for 1 of right triangle, we have
[tex]\sqrt{74} ^{2}[/tex] = [tex]7^{2}[/tex] + [tex](\frac{x}{2}) ^{2}[/tex]
74 = 49 + [tex]\frac{x^{2}}{4}[/tex]
74 - 49 = [tex]\frac{x^{2}}{4}[/tex]
25 = [tex]\frac{x^{2}}{4}[/tex]
therefore, x = [tex]\sqrt{25*4}[/tex] = [tex]\sqrt{100}[/tex] = 10

F(x) = 6 (1/8)^x is an example of
An exponential growth function
A logarithmic growth function
An exponential decay function
A logarithmic decay function
Answer:
Exponential decay. Your growth factor is 1/8, which is between 0 and 1. Thus, the value is decreasing exponentially.
If the growth factor is greater than 1, you have exponential growth. Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.
