Answer: the answer is A

Step-by-step explanation: 400 times 2.5 is 1000 and 250 times 2.5 is 625 and together they equal 1625

Answer:

So for the triangle, we have x = 25 and the angles 45-75-60.

So for the quadrilateral, we have x = 75 and the angles 70-110-75-105.

Step-by-step explanation:

For each of these problems, we can simply add the expressions of the angles given matched to the sum of the angles for the shape given below.  Once we do this, we can solve for x, and then state the given measures of each angle of the shapes.

For the triangle:

60 + ( x + 20 ) + 3x = 180

60 + x + 20 + 3x = 180

60 + 20 + x + 3x = 180

80 + x ( 1 + 3 ) = 180

80 + x ( 4 ) = 180

80 + 4x = 180

4x = 100

x = 25

We have the given angles:

x + 20 ==> 25 + 20 ==> 45

3x ==> 3 (25) ==> 75

60

So for the triangle, we have the angles 45-75-60.

For the quadrilateral:

( x - 5 ) + ( x + 35 ) + x + 1.4x = 360

x - 5 + x + 35 + x + 1.4x = 360

35 - 5 + x + x + x + 1.4x = 360

30 + x ( 1 + 1 + 1 + 1.4 ) = 360

30 + x ( 4.4 ) = 360

30 + 4.4x = 360

4.4x = 330

x = 75

So, we have the given angles:

x - 5 ==> 75 - 5 ==> 70

x + 35 ==> 75 + 35 ==> 110

x ==> 75

1.4x ==> 1.4(75) ==> 105

So for the quadrilateral, we have the angles 70-110-75-105.

Cheers.

Answer:

Step-by-step explanation:

Every 1 hour, 7 screams are caused

the first part is 6 hours, so that means we multiply 6 x 7, which is 42

The second one has 56 screams, so this means we divide 56 and 7 to get 8

The last one is the same as the first one, we multiply 7 and 12 to get 84

Hope this helps : ]

For 6 hours, there are 42 screams, for 8 hours, there are 56 screams and for 12 hours, there are 84 screams.

A proportion is an equation in which two ratios are set equal to each other.

Given that two number lines, one is moving like, 0,1,2,...

And second one is moving like 0,7,14....

Therefore, studying the number lines, we get,

6 hours = 7*6 = 42 screams

8 hours = 7*8 = 56 screams

12 hours = 7*12 = 84 screams

Hence, For 6 hours, there are 42 screams, for 8 hours, there are 56 screams and for 12 hours, there are 84 screams.

Answer:

It is the last one. (16 for 2 tickets)

Step-by-step explanation:

To make it a unit fraction you have to divide the denominator by itself to get 1. 2 divided by 2 equals 1. To keep the fraction equivalent divide the numerator by 2 as well. That equals 8. This makes the unit rate

Step-by-step explanation:

2 times 2=4

The two numbers such that their square roots about 40 apart will be 2401 and 81.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Let's consider the number 8² = 64

Now, 64 - x = 40

x = 64 -40 = 24 and it is not a square of any number.

Take, 7² = 49

49 - x = 40

x = 9 it is a square of 3.

Thus, 7² - 3² = 40

So, 49² = 2401 and 9² = 81

Hence "The two numbers such that their square roots about 40 apart will be 2401 and 81".

Answer:

See Below

Step-by-step explanation:

Take the the given information and compare to the question being asked

[tex]\frac{y}{x}[/tex]. So insert the x & y's of both equations (ima do y over x to make it easier)

[tex]\frac{14}{4} =\frac{y}{40}[/tex]

divide 14/4

3.5 = [tex]\frac{y}{40}[/tex]

then multiply both sides by 40 to isolate y

140 = y

Check by reinserting 140 and divide it by 40

Answer:

y= 140

Step-by-step explanation:

if they are directly proportional, that means when one increases/decreases the other does as well.

x increased by multiplying itself by ten. Like before, since they are both directly proportional that means that y is multiplied by 10.

14*10= 140, y=140
