Answer:

I believe it should be the second answer

Answer:

A. 24

Step-by-step explanation:

We know that the formula for find the area of right triangle is (1/2) × (b × h)

Using this formula, we can find the area of this right triangle given the side lengths

the base of this right triangle is 8

the height of this right triangle is 6

(1/2) × (8×6)

(1/2) × (48)

48/2

Answer:

28 students

Step-by-step explanation:

Let number of students in cooking club = x

Number of students in fencing club = 1/5 x

Number of students in chess club = 2(1/5)x

Since, There are 42 more students in the cooking club than in the chess club

Then ;

Number of students in chess club = Number of students in cooking club - 42

2(1/5)x = x - 42

(2/5)x - x = - 42

(2/5)x - x = - 42

-0.6x = - 42

x = 42 / 0.6

x = 70

Hence, number of students in chess club :

(2/5) * 70 = 28

Answer:

Step-by-step explanation:

Ok, well the first thing you need to do is make -4/13 have the same numerator as 9/26. Thankfully, 26 is a multiple of 13, so that step is easy:

-4/13 -> -8/26

Then you can add them together with ease.

9/26 + -8/26 = 1/26

Adding a negative number to anything is the same thing as subtracting.

Answer:

Riley's hourly rate is $10

Step-by-step explanation:

Riley earned $5 for 1/2 of an hour babysitting. What is her hourly rate?

1/2 of an hour = $5

1 hour = $x

Cross Multiply

1/2 × x = $5 × 1

x = $5 ÷ 1/2

x = $5 × 2

x = $10

Hence, Riley's hourly rate is $10

Answer:

1/10

Step-by-step explanation:

Because there is ten different numbers so therefore it would be 10/1

Thankyou

Answer:

1. y = [tex]\frac{-A}{By}[/tex]x + [tex]\frac{C}{By}[/tex]

2. Divide the Opposite of A and B

3. Doesn't make sense the y-intercept is C/By sry I can't help that one

Step-by-step explanation:

1. Ax + By = C

By = -Ax + C

y = [tex]\frac{-A}{By}[/tex]x + [tex]\frac{C}{By}[/tex]

2. No explanation

Answer:

Calories per cup = 120 calories

Calories in 2 cups = 240 calories

Step-by-step explanation:

Given that:

Number of calories in a [tex]\frac{3}{4}^{th}[/tex] cup serving = 90 calories

To find:

Unit rate for calories per cup = ?

Number of calories in 2 cups of cereal = ?

Solution:

Here we are given the number of calories in a [tex]\frac{3}{4}^{th}[/tex] cup serving.

To find the calories in one cup, we need to divide 90 calories with [tex]\frac{3}{4}[/tex].

So, unit rate for calories per cup can be given as:

[tex]\dfrac{90}{\frac{3}4}\\\Rightarrow \dfrac{90}{3}\times 4\\\Rightarrow \bold{120 \ calories}[/tex]

To find the calories in 2 cups of cereal, we need to multiply the unit rate for calories per cup with 2.

So, calories in 2 cups of cereal = [tex]120 \times 2[/tex] = 240 calories

Therefore, the answer is:

Calories per cup = 120 calories

Calories in 2 cups = 240 calories

Answer:

4/3 (answer choice b)

Step-by-step explanation:

first, you convert the equation to slope intercept form as well as make sure y doesn't have a coefficient by dividing the whole equation by 4. (y=-3/4x+6) Next, you find the reciprocal of the slope which in this case is -4/3 ,and divide it by -1 giving you 4/3.

[tex]125y {}^{5}(7x {}^{5}y)[/tex]

Answer:

233 seconds

Step-by-step explanation:

When h = 0 the jumper ends his/her jump. Therefore let h = 0 so that we can solve for t; forming a quadratic equation

0 = 3t^2 - 700t + 200

I am going to solve  using the quadratic formula, but there are other approaches--

[tex]t_{1,\:2}=\frac{-\left(-700\right)\pm \sqrt{\left(-700\right)^2-4\cdot \:3\cdot \:200}}{2\cdot \:3},\\\\\sqrt{\left(-700\right)^2-4\cdot \:3\cdot \:200} = 20\sqrt{1219},\\\\t_{1,\:2}=\frac{-\left(-700\right)\pm \:20\sqrt{1219}}{2\cdot \:3}[/tex]

[tex]\:t_2=\frac{-\left(-700\right)-20\sqrt{1219}}{2\cdot \:3}[/tex]

[tex]t=\frac{10\left(35+\sqrt{1219}\right)}{3},\:t=\frac{10\left(35-\sqrt{1219}\right)}{3}[/tex]

Now the solutions are around 233 and 0.3 seconds. Given these two solutions I would find the first one more predictable.

Answer:

33 hotdogs and 225 drinks on Monday

Step-by-step explanation:

We would use the ratio of 1:3 hotdogs to drinks

Split the ratio in 450 and we get 112.5:337.5

$112.5 would be the earnings of hotdogs

$337.5 would be the earnings of the drinks

Now we divide each individually by its cost

$112.5/3.5

= 32 1/7,

$337.5/1.5

= 225

We will round the hotdogs to 33 as the word problem says "sold enough to make."

Explanation:

We'll use the zero product property. This is the idea where if A*B = 0, then either A = 0 or B = 0.

So if

-0.7(x+3)(x-4) = 0

then either

x+3 = 0 or x-4 = 0

Both of those equations solve to

x = -3 or x = 4

The roots are the locations of the x intercepts, which is where the graph crosses or touches the x axis.
