THERE ARE 3 BAGS OF APPLES WEIGHING A TOTAL OF 22 1/2 POUNDS. TWO OF THE BAGS WEIGH 6 3/8 POUNDS AND 3 1/4 POUNDS. HOW MUCH DOES

Paraphin [41]

22 1/2= 6 3/8+ 3 1/4+ x
22 1/2= 6+3(3/8+1/4)+x
22 1/2= 9 (3/8+2/8) +x
22 1/2= 9 5/8 +x
22 1/2 -9 5/8 =x
22-9(1/2-5/8)=x
13(4/8-5/8)=x
13 (-1/8)=x
12 7/8

The ratio of the number of Jackie's pink T-shirts to the number of her purple T-shirts is 4:3. Which of the following cannot be

Sidana [21]

Since the number of T-shirts must be a whole number (she cannot use half a t-shirt), the total number must be a multiple of 7 (at least 4 pink t-shirts + 3 purple t-shirts must exist). The only answer choice which is not a multiple of 7 is D) 48.

Brandon has two credit cards and would like to consolidate the two balances into one balance on the card with the lower interest

Nostrana [21]

The amount which Brandon have saved in interest by consolidating the two balances on the card with the lower interest rate is $256.12.

<h3>What is monthly payment?</h3>

Monthly payment is the payment which has to paid against the loan amount or the borrowed money calculated with interest rate.

It can be calculated with the following formula.

$M=P\left (\dfrac{r}{1-(1+r)^{-nt}}\right)$

Here, (P) is the principal amount, (r) is the interest rate and (t) is time.

Brandon has two credit cards and would like to consolidate the two balances into one balance on the card with the lower interest rate.

The table below shows the information about the two credit cards Brandon currently uses.

Cards Amount APR Monthly Payment
Card a $1,463.82 13% $24.60
Card b $1,157.98 17% $22.14

Interest rate for the card a is,

$r=\dfrac{13}{12\times100}=0.01083$

The time period is 8 years and there are 12 months in one year. Thus, the monthly payment of card A will be,

$M=1157.98\left (\dfrac{0.01083}{1-(1+0.01083)^{-12(8)}}\right)\\M=19.47$

In the 8 years, there is total 96 monthly payments. Thus, the total payment by card A is,

$P_a=19.47\times96=1869.12$

For the card B the monthly payment is $22.14. Thus the total payment by card B is,

$P_b=22.14\times96=2125.44$

The difference in the payment is,

$d=2125.44-1869.12\\d=256.12$

Hence, the amount which Brandon have saved in interest by consolidating the two balances on the card with the lower interest rate is $256.12.

Write an equation to represent the relationship shown in the graph. Use the graph below

Lostsunrise [7]

Answer:

$y=x+3$

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

First, we could determine the slope (m). The slope is the $\displaystyle\frac{rise}{run}$ of the line, or the number of units it travels up over the number of units it travels to the right.

Notice how each consecutive point moves up 1 unit and right 1 unit. This makes the slope of the line 1/1, which is just 1:

$y=1x+b\\y=x+b$

Now, to find the y-intercept, we must identify the value of y when the line crosses the y-axis.

The line crosses the y-axis at y=3, so therefore, the y-intercept is 3:

$y=x+3$

I hope this helps!

Saby used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables b

Degger [83]

Short Answers
P(Both) = 0.1792
Givens
The total number of roles = 100
Total number of heads = 56
Number of times rolled a four = 32 [check this for me].

Set up the probabilities.
P(H) = 56/100
P(4) = 32/100
P(H)*P(4) = P(Both)

Substitute and solve
P(Both) = 56/100 * 32/100 = 1792/10000
P(Both) = 112/625 because there are many cancellations. Or you could just express it as 0.1972
