Last one is correct.
1/4 divide 5/6 = 1/4 x 6/5 (flip the fraction upside down to multiply the fraction)

Answer:

$a=4,b=6,c=5$

Step-by-step explanation:

Recall that to divide fractions, you take the dividend and multiply it by the divisor's reciprocal, therefore:

$\frac{1}{4}\div\frac{5}{6}=\frac{1}{4}*\frac{6}{5}=\frac{6}{20}=\frac{3}{10}$

It's easy to see now that $a=4,b=6,c=5$ .

I need help solving this

Stolb23 [73]

Step-by-step explanation:

So in the equation given, y = 2x - 3

you substitute x for whats given in the table in the x column.

Example

In the graph the first number under the x colum is -1.

y = 2x - 3 in the equation you take out x and put -1.

So now the equation becomes y = 2 × -1 - 3.

Using bedmas to solve the question you should get -5

Which now means y = -5

To plot the point now x would be -1 and y would be -5 (-1, -5)

Same thing for the second number in the x Column.

y = 2 × 1 - 3 which equals -1

To plot it

x = 1 y = -1. (1, -1)

And for the last number 3.

Agai. You substitute x for 3 which makes the equation y = 2 × 3 - 3

this gives you 3 and to plot it

x would be 3 and y would be 3

Sue is upholstering a rectangular ottoman that measures 21 centimeters by 18 centimeters by 15 centimeters. What will be the tot

Anika [276]

Answer:

1926cm²

Step-by-step explanation:

Given

Dimension = 21cm by 18cn by 15cm

The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:

$Surface\ Area =2(LB + LH + BH)$

Where L, B and H are the dimensions.

So,

$Surface\ Area = 2(21 * 18 + 21 * 15 + 18 * 15)$

$Surface\ Area = 2(378 + 315 + 270)$

$Surface\ Area = 2(963)$

$Surface\ Area = 2 * 963$

$Surface\ Area = 1926cm\²$

Hence, 1926 cm² of fabrics are needed to cover all surfaces.

The YTM on a bond is the interest rate you earn on your investment if interest rates don’t change. If you actually sell the bond

AURORKA [14]

Answer / Step-by-step explanation:

(a) The rate of return you expect to earn if you purchase a bond and hold it until maturity is the YTM.

If we recall the bond price equation for this bond is, we have

P0 = $1,060 = $100(PVIFAR%,21) + $1,000(PVIFR%,21)

Using a spreadsheet, financial calculator, or trial and error we find:

R = YTM = 9.42%

b) To find our HPY, we need to find the price of the bond in two years. The price of the bond in two years at the new interest rate, will be:

P2 = $100 (PVIFA 8.42%,17) + $1,000(PVIF 8.42%,17)

Therefore, P2 = $1,139.6

(b2) To calculate the HPY, we need to find the interest rate that equates the price we paid for the bond with the cash flows we received. The cash flows we received were $100 each year for two years and the price of the bond when we sold it. The equation to find our HPY is therefore:

P0 = $1,060 = $100(PVIFAR%, 2) + $1,139.69(PVIFR%, 2)

Solving for R, we get:

R = HPY = 13.52%

Therefore, the realized HPY is greater than the expected YTM when the bond was bought because interest rates dropped by 1 percent; bond prices rise when yields fall.
