Answer:

Carter family = 25 hours

Davis family = 31 hours

Step-by-step explanation:

Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.

So combined:

x + y = 45 hours

and we are also told that:

40x + 15y = 1300 L

So we can do simultaneous equations to solve the problem.

With some rearranging, we can figure out that:

y= 45 - x

and by substituting that into the second equation:

40x + 15 (45 -x) = 40x + 675 - 15x = 1300L

25x = 1300 - 675

25x = 625

x = 25 = hours that the Carter family used their sprinkler

and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:

25 + y = 56

y = 31

The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.

Which Is Most Likely To Weigh 4 Tons?
A A Watermelon
B A Man
C A Clothes Dryer
D A Helicopter
(30 points)

Answers

The most likely object to weigh 4 tons will be Helicopter

The correct option is (D) Helicopter

What is ton in kg?

1 ton = 1000 Kg

First, a watermelon weigh= 0.001 to 0.003  tons(i.e., 1-3 Kg)

then, A man weigh= 0.09 to 0.1 tons (i.e., 90 - 100kg)

A clothes dryer weigh= 0.07 to 0.09 tons (i.e., 70- 90 Kg)

lastly, a Helicopter weigh= 0.275- 56 tons (i.e., 275 - 56,000 Kg)

The closest is Helicopter weight 0.275- 56 tons

Answers

The length 11 cm is closer to the length of the diagonal of this square in centimeters.

How to determine the value of x?

The equation is given as:

x^2 = 132

Take the square root of both sides

x = √132

Evaluate the square root

x = 11.49

#6 You want to find out what type of pet is most commonly adopted from the shelter. Over the course of a month, you randomly survey 40 people who have just adopted a pet. Of those 40 people, 23 adopted dogs. If about 4,500 people adopt pets each year, about how many can you predict will dogs?​

Answer:

we predict 2,587 persons will adopt dogs

Step-by-step explanation:

out of 40×25 persons 23×25 adopt dogs

Then

out of 1000 persons 575 adopt dogs

Then

Instructions: Find the measure of the indicated angle.

Answers

Answer:

x = 35

Step-by-step explanation:

As it is an isosceles triangle, two sides are equal (that's why we took two x)

2x = 180- 110

2x = 70

x = 70/2

x = 35

I hope my answer helps you.

The measure of the indicated angle is 35 degrees.

What is the angle sum property?

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

We are given that;

Angle = 110degree

Now,

x+x+110=180

2x+110=180

2x=180-110

2x=70

x=70/2

x=35

Therefore, by the angle sum property of triangles the answer will be 35degree.

It is common knowledge that a fair coin lands heads up 50% of the time and tails up 50% of the time. For fair coins, a probability of 0 is assigned to the coin landing on its edge. But what if several coins were glued together? A teacher claims that if 10 pennies were glued together and flipped many times, the penny stack would land on heads 25% of the time, tails 25% of the time, and on its edge 50% of the time. To investigate this claim, a student glues 10 pennies together and flips the stack 200 times. The student would like to know if there is convincing evidence that the distribution differs from what the teacher claimed. What are the appropriate hypotheses?

The lines represented by these equations are
(1) parallel
(2) the same line
(3) perpendicular
(4) intersecting, but not perpendicular

Answers

Using linear function concepts, it is found that the two lines can be classified as:

(4) intersecting, but not perpendicular.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The slope defines if the lines are parallel or perpendicular, as follows:

If they are parallel, they have the same slope.If they are perpendicular, the multiplication of the slopes is of -1.If the multiplication of -1, and the slopes are different, they are intersecting.

In this problem, the lines in slope-intercept formula are:

[tex]y = \frac{2}{3}x - 2 \rightarrow = m = \frac{2}{3}[/tex]

[tex]y = \frac{3}{2}x + 3 \rightarrow m = \frac{3}{2}[/tex]

Then:

[tex]\frac{2}{3} \times \frac{3}{2} = 1[/tex]

So they are intersecting and not perpendicular, which means that option 4 is correct.

The sum of all but one interior angle of a heptagon is 776°. What is the measure of the final interior angle? 42º 56º 124º 304º.

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 7 ( heptagon has 7 sides ) , then

sum = 180° × 5 = 900°

let x be the final interior angle , then

776° + x = 900° ( subtract 776° from both sides )
