Mathematics

Answer:

≈23.66

Step-by-step explanation:

Height ---> x

base ---> 5x

<em>Formula for area of triangle: (base*height)/2</em>

((5x)(x))/2 = 1400

5x^{2}/2 = 1400

5x^{2} = 1400 · 2 = 2800

x^2 = 2800/5 = 560

x= √560 ≈ 23.66

At a shelter, 15% of the dogs are puppies. there are 60 dogs at the shelter. How many are puppies?
frutty [35]
So for this you need to find 15% of 60. There are a few ways to do this but I prefer to do it like this.

First, find 10% of 60. This can be found by dividing 60 by 10, because 100%/10% is 10.

This gives 10%=6

5% is half of 10%, so divide your answer for 10% (6), by 2.

This gives 5%=3

We needed 15%, so we add our 10% and 5% together, to get 9.

15% of 60 is 9, meaning there are 9 puppies.

Hope this helps!

HELP IM DESESPERATED PLSSSSSSSS ITS THE 4TH TIME I POST PLSSSSSSSS 6th GRADE MATH
Serga [27]

Answer:

Step-by-step explanation:

Three times a number plus 8 girls would be

3x+8

The variable is x

The constant is 8

and the coefficient is 3

If Trey now has 9 times as many cards as he did when he began collecting, we can use the number of cards he had before as x.

Trey has 9x cards.

The variable in this equation is x and the constant is 9

If Nina has 3 dimes and 1 nickel in her pocket, we can say the dimes are b and the nickel is c

If she found some quarters on the ground, we can say the quarters are A, but we don't know how many, so we need x to represent how many quarters. the Variables in this equation are B, C, and A (b, c, and a)

We can write this in an equation as

3b+c +(ax) the coefficient is x, and the constant is 3

In the equation 2n+4, the variable is n, the coefficient is 4, and the constant is 2

A word problem for this equation could be:

Ray collects marbles. Ray's friend gave him 2 times as many marbles as he already had, and he found 4 marbles on the way home from his friend's house.

11111nata11111 [884]

Answer:

Required probability is 0.784 .

Step-by-step explanation:

We are given that in a large statistics course, 74% of the students passed the first exam, 72% of the students pass the second exam, and 58% of the students passed both exams.

Let Probability that the students passed the first exam = P(F) = 0.74

     Probability that the students passed the second exam = P(S) = 0.72

     Probability that the students passed both exams = P(F \bigcap S) = 0.58

Now, if the student passed the first exam, probability that he passed the second exam is given by the conditional probability of P(S/F) ;

As we know that conditional probability, P(A/B) = \frac{P(A\bigcap B)}{P(B) }

Similarly, P(S/F) = \frac{P(S\bigcap F)}{P(F) } = \frac{P(F\bigcap S)}{P(F) }  {As P(F \bigcap S) is same as P(S \bigcap F) }

                          = \frac{0.58}{0.74} = 0.784

Therefore, probability that he passed the second exam is 0.784 .
