Ieryl spends a total of $68.82 for 2 pairs of sneakers

1 answer:

7 0

Each pair of sneakers cost 30.25 because if you add the $3 plus the $5.32 it’s $8.32 so you do $68.82-$8.32 which is $60.05 and you divide it by 2 so it’s $30.35

Y=x+3over 8 proportional or nonproportional

Inessa [10]

Answer:

nonproportional

Step-by-step explanation:

x + 3

------- is definitely nonproportional. The reason for this is that the graph (a

8 straight line) does not pass through the

origin; it's offset by 3/8 unit up from the

origin.

mrs.saledo wants to buy 1 1/2 quarts of whipping cream if whipping cream is sold in only 1 pint containers , how many containers

hram777 [196]

Answer:

She needs to buy 3 such containers.

Step-by-step explanation:

Mrs. Saledo wants to buy $1\frac{1}{2}$ quarts of whipping cream.

Now, $1\frac{1}{2}$ quarts = $\frac{3}{2}$ quarts = $\frac{3}{2} \times 2 = 3$ pints.

Since we know that 1 US liquid quart = 1 US liquid pints.

If the whipping cream is sold in only 1 - pint containers, then she needs to buy 3 such containers. ( Answer )

Jerome, Kevin, and Seth shared a submarine sandwich.

Elanso [62]

Seth at 1 - 1/2 - 1/3 = 1/6 of the sandwich.

Therefore the ratio is:

1/2 : 1/3 : 1/6

Multiply everything by 6:

3: 2: 1 D

2^5×8^4/16=2^5×(2^a)4/2^4=2^5×2^b/2^4=2^c A= B= C= Please I'm gonna fail math

Answer:

a = 3, b = 12, c = 13

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

(a^b)^c = a^(bc)

___

You seem to have ...

$\dfrac{2^5\times8^4}{16}=\dfrac{2^5\times(2^3)^4}{2^4}\qquad (a=3)\\\\=\dfrac{2^5\times2^{3\cdot4}}{2^4}=\dfrac{2^5\times2^{12}}{2^4}\qquad (b=12)\\\\=2^{5+12-4}=2^{13}\qquad(c=13)$

_____

Additional comment

I find it easy to remember the rules of exponents by remembering that an exponent signifies repeated multiplication. It tells you how many times the base is a factor in the product.

$2\cdot2\cdot2 = 2^3\qquad\text{2 is a factor 3 times}$

Multiplication increases the number of times the base is a factor.

$(2\cdot2\cdot2)\times(2\cdot2)=(2\cdot2\cdot2\cdot2\cdot2)\\\\2^3\times2^2=2^{3+2}=2^5$

Similarly, division cancels factors from numerator and denominator, so decreases the number of times the base is a factor.

$\dfrac{(2\cdot2\cdot2)}{(2\cdot2)}=2\\\\\dfrac{2^3}{2^2}=2^{3-2}=2^1$

Evaluate the expression. 6 to the third power + 5( 8 + 15)

olya-2409 [2.1K]

Answer:

5083

Step-by-step explanation:

6^3 + 5(8 + 15)

Simplify the bracket first

6 x 6 x 6 + 5 (23)

216 + 5 (23)

221 (23)

221 x 23 = 5083
