Brian invests £6500 into his bank account.

Mathematics
1 answer:
Mashcka [7]3 years ago
8 0

Answer:

approximately 11 years

Step-by-step explanation:

Use the compound interest formula:

A = P(1+r)^n, where r is the annual interest rate as a decimal fraction and t is the number of years.

Here we have:

(10000 pounds) = (6500 pounds)(1 + 0.04)^t and must find the value of t.

Solve for (1.04)^t by dividing both sides of this equation by (6500 pounds):

1.5385 = 1.04^t

Take the log of both sides:

log 1.5385 = t*log 1.04, or

       log 1.5385

t = --------------------  = (0.1871)/0.0170  =  10.98, or approximately 11 years

         log 1.04

Elanso [62]

Answer:

The correct option is A. 198 degrees

Step-by-step explanation:

Consider the provided information.

87 percent of students worked at least sometime during their undergraduate career and 13 percent did not work at all.

Another question showed that 32 percent of the students worked throughout their undergraduate career.

87 percent  of the students worked at least sometime during the college. Out of them 32% worked throughout the college.

Therefore, the students who worked sometime during their undergraduate career, but not throughout are:

(87-32)% = 55% .

As we know the angle measure in circle  is 360 degrees.

55% of 360° is:

\frac{55}{100}\times360= 198

Hence, the measure of central angle would be 198 degrees

Therefore, the correct option is A. 198 degrees

First of all, your fractions that you wrote were wrong. You flipped the numbers over. When you're finding the slope of a graph, the number on the y-axis is always the numerator while the x-axis is the denominator. 

Your first answer would be the actual slope- which is 3.

Your second answer would be the number of products that company would sell if the got 1,000 web views So just multiply 3 by 1,000. That means that the company will sell 3,000 products.

Can you help me in this plz ​
Kipish [7]

Answer:

£ 38,110

Step-by-step explanation:

We need to find salary for 1 year (12 months).

  • Monthly Salary = 1410, so yearly would be:

1410 * 12 = 16,920

  • 26% of total profit. Let's find the profit first:

Profit is Income - Cost

So, that would be (from table):

Profit = 549000 - 473500 = 75,500

26% of that would be:

26/100 = 0.26

0.26 * 75,500 = 19,630

  • 390 bonus for each month she sells atleast 16 cars

Out of 12 months (1 year), she sold at least 16 cars in 4 months, so she gets bonus of 390 for those 4 months, that would make:

390 * 4 = 1560

Total Pay for the year would be summation of all these:

Total Pay = 16,920 + 19,630 + 1560 = £ 38,110
