Answer:

1x + 4y = 4 ⇒ 6x + 24y = 24

6x - 8y = 0 ⇒ 6x - 8y = 0

32y = 24

32 32

y = 3/4

x + 4(3/4) = 4

x + 3 = 4

-3 -3

x = 1

(x, y) = (1, 3/4)

Step-by-step explanation:

Daniel uses \large \frac{2}{3}cup of orange juice for every \large \frac{1}{4}cup of carrot juice to make his drink. Enter the n

USPshnik [31]

Answer:

$\dfrac{8}{3}\ \text{cups of orange juice}$ or $2\dfrac{2}{3}\ \text{cups of orange juice}$ is used

Step-by-step explanation:

Daniel uses the proportions of $\dfrac{2}{3}$ cups of orange juice and $\dfrac{1}{4}$ cups of carrot juice to make a mixed juice.

Now, in the question 1 cup of carrot juice is used. So 4 times of the proportion of the carrot juice is used. Accordingly 4 times of the cups of orange juice will be used.

$\dfrac{2}{3}\ \text{cups of orange juice}=\dfrac{1}{4}\ \text{cups of carrot juice}\\\Rightarrow 4\times \dfrac{2}{3}\ \text{cups of orange juice}=4\times \dfrac{1}{4}\ \text{cups of carrot juice}\\\Rightarrow \dfrac{8}{3}\ \text{cups of orange juice}=1\ \text{cup of carrot juice}$

So for one cup of carrot juice $\dfrac{8}{3}\ \text{cups of orange juice}$ or $2\dfrac{2}{3}\ \text{cups of orange juice}$ is used.

Answer pls thank you

frosja888 [35]

Answer:

d = 5/6t

Step-by-step explanation:

5 stories every 6 seconds

at 12 seconds, it would have travelled 10 seconds.

using this 2 data in this formula

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

Note : d = y, t = x;

d1 = 5, t1 = 6, d2 = 10, t2 = 12

we have

(d - 5)/(t-6) = (10-5)/(12-6)

(d - 5)/(t-6) = 5/6

d = 5/6(t-6) + 5

d = 5/6t -5+5

d = 5/6t

25% of all who enters a race do not complete. 30 haveentered.

nikklg [1K]

Answer:

The probability that exactly 5 are unable to complete the race is 0.1047

Step-by-step explanation:

We are given that 25% of all who enters a race do not complete.

30 have entered.

what is the probability that exactly 5 are unable to complete the race?

So, We will use binomial

Formula : $P(X=r) =^nC_r p^r q^{n-r}$

p is the probability of success i.e. 25% = 0.25

q is the probability of failure = 1- p = 1-0.25 = 0.75

We are supposed to find the probability that exactly 5 are unable to complete the race

n = 30

r = 5

$P(X=5) =^{30}C_5 (0.25)^5 (0.75)^{30-5}$

$P(X=5) =\frac{30!}{5!(30-5)!} \times(0.25)^5 (0.75)^{30-5}$

$P(X=5) =0.1047$

Hence the probability that exactly 5 are unable to complete the race is 0.1047

How do I solve out 5x188

mihalych1998 [28]

Answer:

940

Step-by-step explanation:

188

× 5

940

--------------------------------------------------------

8 * 5 = 40

Carry the 4 to the next 8

8 * 5 = 40

Add the 4 to the 40

40 + 4 = 48

Carry the 4 to the 1

1 * 5 = 5

Add the 4

5 + 9

= 940

*Hope this helps .^.*

CAN SOMEONE HELP ME UNDERSTAND THIS PLEASE

ICE Princess25 [194]

YEAH OFC SHAWTY!

so for A its -4^11 because if the powers have the same base and they are being multiplied you add the powers

For B its the same idea, they have the same base, and are being multiplied so you add the powers- 13^9

For C its similar, you have the same base, but since its Dividing, you subtract the powers. So, 9^5
for D you pretend like the denominator has a power of 1 and subtract. So its -24^5-24^1 which hopefully puts it into perspective of being -24^4 becuase we subtracted the powers

I cant do 2 right now, but i will in a minute

And for 3 his mistake is that they arent the same bases so he cant add the powers, he should have converted them to the same base first.
