Answer:

1) c and d

2) 44

3) a and c

1: if 96 is the 100% price and 32% is what you need to find, it is 32 out of 100. 0.32 is the same, as well as 32/100.

2: if you divide the shape into different pieces, i find it easier to find the area. 9 x 3 = 27. 4 x 2= 8. 3 x 3 = 9. 27+8+9=44.

3: the ratio 8:20 can be simplified down to 2:5 which makes A true. if the ratio is originally blue:red, then for c, 10:4 is the same as 4:10 since it states red to blue instead of blue to red, meaning c is also true.

Answer:

1. C and D.

2. 34

3. A and C

Step-by-step explanation:

1. All you have to do is solve each equation in order to see which ones are equal to the same answer

A. 32 * 96 = 3072

B. 3.2 * 96 = 307.2

C. 0.32 * 96 = 30.72

D. 32/100 * 96 = 30.72

Both C and D have the same answer.

2. Add up all the sides

9+6+5+4+3+3+2+2= 34

3. Look at each answer carefully.

A. There are 2 blue cubes for every 5 red cubes. True

B. When the game has 56 cubes in all, there are 40 red cubes. False

C. The ratio of red to blue cubes is 10:4. True

D. The ratio of all cubes to blue is 28:20. False

450 g in the ratio 2:13

jonny [76]

450 g in 2:13

Total proportion asked for =2+13=15

Now comparing g with ratio, or whatever

450/15=30g $\implies$ Therefore 1 in ratio depicts of 30g

So final answer = $\boxed{60g : 390g}$

More to know, daily bit of knowledge: The Binomial Theorem:

$\boxed{{(a+b)} ^n= \sum_{k=0}^{n}\binom{n}{k} a^{n-k}b^{k}}$

Country days scholarship rounds receive a gift of $135000. The money is invested in stock, bonds, and CDs. CDs pay 2.75% interes

Vsevolod [243]

Answer:

CDs — $10,000
bonds — $80,000
stocks — $45,000

Step-by-step explanation:

Let the variables c, b, s represent the dollar amounts invested in CDs, stocks, and bonds, respectively. Then the problem statement gives us 3 relations between these 3 variables:

c + b + s = 135000 . . . . . . . . . . . . . . . . . total invested

0.0275c +.045b +0.104s = 8555 . . . . . total income earned

-c + b = 70000 . . . . . . . . . . . . . . . . . . . . . 70,000 more was in bonds than CDs

Using the third equation to write an expression for b, we can substitute into the other two equations.

b = 70000 +c . . . . . . . . . . . . . . . . expression we can substitute for b

c + (70000 +c) +s = 135000 . . . . substitute for b in the first equation

2c +s = 65000 . . . . . . . . . . . . . . . . [eq4] simplify

.0275c +.045(70000 +c) +.104s = 8555 . . . . . substitute for b in 2nd eqn

.0725c +.104s = 5405 . . . . . . . . . . [eq5] simplify

Using [eq4], we can write an expression for s that can be substituted into [eq5].

s = 65000 -2c . . . . . . . expression we can substitute for s

0.0725c +0.104(65000 -2c) = 5405

-0.1355c = -1355 . . . . . . . . . . . . . . . . . . . . subtract 6760, simplify

c = 1355/.1355 = 10,000

s = 65000 -2×10000 = 45,000

b = 70000 +10000 = 80,000

The amounts invested in stocks, bonds, and CDs were $45,000, $80,000, and $10,000, respectively.

Alternatively, you can reduce the augmented matrix for this problem to row-echelon form using any of several calculators or on-line sites. That matrix is ...

$\left[\begin{array}{ccc|c}1&1&1&135000\\0.0275&0.045&0.104&8555\\-1&1&0&70000\end{array}\right]$
