A park has a ratio of basketballs
to soccer balls that is 7:10. What
fraction of these balls are soccer
balls?

Answer:

The answer is 4,380

Step-by-step explanation:

I took the test

The final altitude of the hot air balloon is 4380 feet.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its value and then multiply it by 100.percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.

As per the given data:

Initial altitude of the balloon = 4000 feet

First altitude reduces by 3%.

Second time it increases by 500 feet.

Decrease in altitude for first time = 4000 × (3/100) = 120 feet.

Altitude after first time = 4000 - 120 = 3880 feet

Altitude after second time = 3880 + 500 = 4380 feet

final altitude of the hot air balloon = 4380 feet

Hence, the final altitude of the hot air balloon is 4380 feet.

THE A N S QW ER

Answer:

The Energizer Pack

Step-by-step explanation:

To figure this out I would divide to find the price per thing then compare.

So 2.97 divided by 4 is 0.7425. We'll round that later if we have to.

12. 39 divided by 10 is 1.239

Now we compare. Which is cheaper, or less - 0.74 or 1.24?

0.74 is less, so that means the Energizer pack is the better buy since it's cheaper.

Please mark brainliest if possible and i hope you get a good grade on youe homework! :)

Answer:

Step-by-step explanation:

We know that:

Solution:

Looking at the cost per battery pack, we can say that 4 packs of Energizer is a better buy because its cost per pack is lower than the cost of 10 packs of Duracell batteries.

Hoped this helped!

Answer:

2.04

Step-by-step explanation:

100% + 104% = 204%

204 ÷ 100 = 2.04

Answer:

s = 4

Step-by-step explanation:

3(s + 8) = 36

Simplify the distributive property:

⇒ 3s + 24 = 36

Subtract 24 both sides:

⇒ 3s = 36 - 24

⇒ 3s = 12

Divide 3 both sides:

⇒ 3s/3 = 12/3

⇒ s = 4

Answer:

3

Step-by-step explanation:

1. open the bracket

i.e_ 2(a)=6

is 2×a=6

2. sum it up

2×a=6

=2a=6

3. divide both sides by the co-efficient of a which is 2.

2a\2a = 6\2a

=3a

therefore, a is 3

From the information given, the differential equation will be di/dt = (E - Ri) / L.

From the information given, we can set up the differential equation as:

-E(t) = Ldi(t)/Dr + Ti(t) = 0.

Here, i(t) = I

E(t) = E

Therefore, this will be:

= -E + Ldi/dt + Ri = 0

We'll now solve for di/dt

Ldi/dt = E - Ri

di/dt = (E - Ri) / L

Answer: D. 5 - x^4

Step-by-step explanation: We can see that the blue function is translated three units up, and inverted, so its leading coefficient is negative. The blue function can be rewritten as -x^4 + 3 to reflect these transformations. The only difference between the blue and the red function is that the red is two units higher, or five units total from the origin. Since they are the same shape, it will have a -x^4 in the formula, but since it is translated five units up its formula will be -x^4 + 5, which is also equal to 5 - x^4.

[tex]tan(x)=2.5\implies \measuredangle x=tan^{-1}(2.5)\implies \measuredangle x\approx \begin{cases} \stackrel{I~Quadrant}{68.2^o}\\\\ \stackrel{III~Quadrant}{248.2^o} \end{cases}[/tex]

Make sure your calculator is in Degree mode, Check the picture below on the left side.

well, the tangent recall is sine/cosine, or namely y/x, for that fraction if either of them is negative, the whole fraction is negative, if both are either positive or negative, the fraction is positive.

given such, on the 1st quadrant and 3rd quadrant that fraction y/x is positive because on the 1st quadrant both are positive and on the 3rd quadrant both are negative, yielding the fraction, namely tangent, positive.

[tex]cos(x)=-0.7\implies \measuredangle x=cos^{-1}(-0.7)\implies \measuredangle x\approx \begin{cases} \stackrel{II~Quadrant}{134.43^o}\\\\ \stackrel{III~Quadrant}{225.57^o} \end{cases}[/tex]

now, check the picture below on the right side, cosine or namely "x", is negative on the 2nd and 3rd quadrants only, the first angle you'd get from your calculator will be 134.43°, now, this one is on the 2nd quadrant, so it has a margin from 180° of 180 - 134.43 = 45.57, that means the angle of reference is 45.57° in red in the picture.

to get the 2nd angle on the 3rd quadrant, we add to 180° the reference angle, so 180 + 45.57 = 225.57°.
