Answer:

c

Step-by-step explanation:

7^5 means that there are 5 7s eg 2^4 would be 2×2×2×2

The solution set of the given inequality is  {b| b > 20}.

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.

Answer:

m=-2

Step-by-step explanation:

the formula for slope (m) is (y2-y1)/(x2-x1)

the given points are (3,-7) and (4,-9)

label the points;

x1=3

y1=-7

x2=4

y2=-9

substitute into the equation:

m=(-9--7)/(4-3)

m=(-9+7)/(1)

m=-2/1

the slope is -2

Answer:

8 batches

Step-by-step explanation:

A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?

From the above question, 1 recipe = 1 batch of cookies

Hence:

2/3 cup of sugar = 1 batch of cookies

5 1/3 cups of sugar = x batches of cookies

Cross Multiply

2/3 cup × x batches = 5 1/3 cup × 1 batch

x batches = 5 1/3 cup × 1 batch/2/3 cup

x batches = 16/3 ÷ 2/3

x batches = 16/3 × 3/2

= 8 batches

Therefore she made 8 batches

Answer: -2x²+2x-10

Step-by-step explanation:

Rephrase the expression

Subtract 4x²-7x+6 from 2x²-5x-4

(2x²-5x-4)-(4x²-7x+6)

Expand parenthesis

2x²-5x-4-4x²+7x-6

Put like terms together

(2x²-4x²)+(7x-5x)-(4+6)

Combine like terms

-2x²+2x-10

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.

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.

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

Answer:

tan y°

Step-by-step explanation:

by using the Sine Rule (See attached), we can form the equation:

[tex]\frac{r}{sin (y)} = \frac{p}{sin (x)}[/tex]

rearranging this, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(x)}[/tex]   ---------------------eq 1

Recall that all internal angles of a triangle must sum to 180°. we observe that we have a right triangle where one of the angles is 90°. It then follows that the sum of the other two angles must sum to 90°

i.e x + y = 90°

with a little rearranging, we get

x = (90° - y)

Substituting this into eq 1 above, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(90- y)}[/tex]  ---------eq 2

recall that from the trigonometric co-function identities,

sin (90°- y) = cos y

substituting this into eq 2 gives :

[tex]\frac{r}{p} =\frac{sin(y)}{cos(y)} = tan(y)[/tex]   (answer)
