what is 3/4b>15 solution
The solution set of the given inequality is {b| b > 20}.
How to solve the inequality?Here we have the inequality (3/4)b > 15 and we want to solve it. To do so, we just need to isolate the variable b.
And to do it, we can work with this like we would do with any equation, we can just multipy both sides by (4/3) so we get:
(4/3)*(3/4)*b > 15*(4/3)
b > 20
Then the solution set can be written as {b| b > 20}
That is the set of all values larger than 20.

A rectangle has side lengths of x+1 and 1. What is an expression for the area of the rectangle?
These are the choices...
3
x + 1
x + 2
2x + 3
Thank You!!!
Answer:
x+1 SQUARE units
Step-by-step explanation:
Area of a rectangle is height times width or you could just say the length on one side times the length of a side right next to it.
If the rectangle is x+1 units long and 1 unit high, then the answer is (x+1) x 1 = x +1 because anything times 1 is always just what you started with.
the measure of the seven angles in a pentagon measure 87, 105, 135, and 92. what is the measurement of the last angle
Answer:
121
Step-by-step explanation:
If you add them all up, 87+105+135+92= 419
the pentagon is equal to 540 degrees so minus 540 by 419
then you get 121

1 Jesy invests £8000 for n years in a savings account.
To find the value, V, of her investment after n years she uses the formula:
V = 8000 × (1.025)n
(a) Write down the annual rate of interest Jesy earns.
(b) Find the total amount of interest Jesy earns in three years.
(Total for question 1 is 3 marks)
Answer:
2.5% , $8608
Step-by-step explanation:
Given data
From the given the expression V = 8000×(1.025)^n
The rate is given as
2.5%
For n= 3
The total amount is
V = 8000 × (1.025)^3
V= 8000*1.076
V= $8608
Hence the final amount is $8608

which of the following quadratic will have a maximum value at x=3
(A) y=x^2-6x+19
(B) y=-4x^2+24x-21
(C) y=-2x^2+20x-49
(D) y=2x^2-3x+7
The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.
The maximum and minimum values of a function:
The maximum and minimum values are the highest and lowest values that a function can reach over a particular domain.
For example, in a quadratic function, the maximum or minimum value is the highest or lowest point on the graph, respectively.
If a function has a maximum value, it means that the function reaches its highest point at a certain value of x.
On the other hand, if a function has a minimum value, it means that the function reaches its lowest point at a certain value of x.
Here we have
(A) y = x²-6x +19
At x = 3
y = (3)² - 6(3) + 19
= 9 - 18 + 19 = 10
(B) y = -4x²+24x -21
At x = 3
y = -4 (3)² + 24(3) - 21
= - 4(9) + 72 - 21
= 15
(C) y= -2x² +20x -49
At x = 3
y = - 2 (3)² + 20(3) - 49
= - 18 + 60 - 49
= - 7
(D) y = 2x² -3x +7
At x = 3
y = 2(3)³ - 3(3) + 7
= 18 - 9 + 7
= 16
Therefore,
The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.

pls help fast also need steps
Answer:
x= 2
Step-by-step explanation:
7x = 13x -12
0= 13x-12-7x
12= 13x-7x
12= 6x
2= x
you need to bring all the X's to one side then solve from there
Answer:
x=2
Step-by-step explanation:
7x=13x-12
Subtract 13x from both sides
7x-13x=13x-12-13
-6x=12
Divide both sides by -6

Find the value of the missing base:
Answer:
25 (with assumptions)
Step-by-step explanation:
ASSUMING ES=SD and FT=TG, then the difference between EF and ST is the same as the difference between ST and DG. Since ST - EF = 19 - 13 = 6, then DG - ST = 6 or DG - 19 = 6, add 19 to both sides and DG = 25
Find Sin D and sin E! Write the answer as a fraction and as a decimal. Round to four decimal places, if necessary! Please help me!
Answer:
sine D = 0.9459
sine E = 0.3243
Step-by-step explanation:
Mathematically, sine is the ratio of the opposite to the hypotenuse
The hypotenuse is the longest side and we have it as 37 in the diagram given
the opposite to angle E is 12
So the sine of E = 12/37 = 0.3243
For D , its opposite is 35
The sine of D = 35/37
sine of D = 0.9459

If Earth's total mass is 6 x 10^24 kg, what proportion of this is lost every year?
Step-by-step explanation:
This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.

Chenelle has a savings account that earns 5% simple interest each year. She can only deposit small amounts into her account each month. Should Chenelle keep her account open even though she can deposit only a small amount each month?
Answer:
Yes, she should.
Step-by-step explanation:
5% may not seem like a lot. Lets say she deposits $20 per month. That's $240 a year. Lets also say you keep this for 6 years, you'll have $72 from interest. The more amount she puts in the more she'll gain.
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 240 × 0.05 × 6 = 72
I = $ 72.00
The simple interest accumulated
on a principal of $ 240.00
at a rate of 5% per year
for 6 years is $ 72.00.
Yes, she should keep her account open even though she can deposit only a small amount each month.
Calculation of keeping the account:Since Chenelle has a savings account that earns 5% simple interest each year.
So here we assume that she deposit $20 per month
So for year it should be 240
And the number of years should be 6 so the interest be like 72
Now
I = 240 × 0.05 × 6
I = 72
Hence, Yes, she should keep her account open even though she can deposit only a small amount each month.
