5x + 2y = 20
5 X 0.3 + 2y = 20
1.5 + 2y = 20
2y = 20 - 1.5
2y = 18.5
y = 18.5/2
y = 9.25

Thus, y equals 9.25

To solve this equation, firstly substitute 0.3 for x and then work out y.

5(0.3) + 2y = 20

We’ll start by multiplying the numbers on the left side.

1.5 + 2y = 20

The next step involves subtracting 1.5 from both sides to isolate the variable.

2y = 18.5

Finally, we divide each side by 2 to solve for y completely.

y = 9.25

Thus, the resulting value for y is 9.25.

I hope this assists!

babunello [3635]

The sale price S (in dollars) of an item is calculated using the formula

S = L - rL, where L represents the list price (dollars) and r denotes the discount rate.

Rearranged, this becomes:

rL = L - S

and thus

r = $\frac{L-S}{L}$

which simplifies to

r = $1-\frac{S}{L}$

Given the shirt's list price is $30, we will compute the discount rate accordingly.

Hence, the discount rate r equals $1-\frac{S}{30}$ .

Scarlett is trying to find the height of a dam. She stands 90 meters away from the dam and records the angle of elevation to the

Inessa [3907]

Response:

45.54m

Step-by-step breakdown:

See the provided figure

Scarlett's height is represented as AB = 1.65 meters

She stands 90 meters away from the dam, so BE = AC = 90 m

Scarlett measures the angle of elevation to the dam's summit at 26º, which is ∠DBE = 26°

Height of the Dam = DC = EC+DE

AB = EC = 1.65

In triangle BDE

$Tan \theta = \frac{Perpendicular}{Base}$

$Tan 26^{\circ} = \frac{DE}{BE}$

$Tan 26^{\circ} = \frac{DE}{90}$

$0.48773 \times 90=DE$

$43.89=DE$

Height of the Dam = DC = 1.65 + 43.89 = 45.54 m

Therefore, the dam's height is 45.54 m.

A national survey of 50,000 sixth graders asked if they know what they would like to do when they get older. Suppose you ask 350

AnnZ [3877]

You surveyed 350 students, out of which 182 were unsure.

The calculation gives: 182/350 = 0.52, indicating that 52% of the students were uncertain.

Now, apply this percentage to the national survey total:

50,000 x 0.52 = 26,000

The final result is 26,000 students who wouldn't know.

Samir is an expert marksman. When he takes aim at a particular target on the shooting range, there is a 0.950.950, point, 95 pro

PIT_PIT [3919]

The question appears to be incomplete. Here’s the complete inquiry:

Samir is quite skilled with the gun. When he targets a specific aim at the shooting range, he has a 0.95 probability of striking it. On one occasion, Samir sets out to shoot 10 targets consecutively.

If he has the same chance of hitting each of the 10 targets, what is the likelihood that he will miss at least one?

Response:

40.13%

Step-by-step breakdown:

Let 'A' represent the event of successfully hitting all targets in 10 trials.

The complement of 'A' is $\overline A=\textrm{Missing a target at least once}$

Now, since Samir has a consistent probability of hitting each target at 0.95.

Now, $P(A)=0.95^{10}=0.5987$

We know that the combined probability of an event and its complement equals 1.

<pThus, $P(A)+P(\overline A)=1\\\\P(\overline A)=1-P(A)\\\\P(\overline A)=1-0.5987\\\\P(\overline A)=0.4013=40.13\%$

Consequently, the probability that he misses at least one target among 10 attempts is 40.13%.
