Answer:

0.45 is more

Step-by-step explanation:

:)

The square root of the number is √0.45 = 0.670 is greater than 0.229

Given data ,

Let the first number be represented as p

where the value of p = 0.45

Let the second number be represented as q

where q = 0.229

Now , the square root of the number is expressed as

A = √p

The radical form of a number refers to expressing a number using a radical symbol (√) to represent a root.

It is used to express the roots present in the number.

So , A = √0.45

On simplifying , we get

A = 0.670

And , the value of A > q

So , 0.670 > 0.229

Hence , the square root is A = √0.45 = 0.670

Answer:

Length = 6.1 inches and Width = 3.4 inches

Step-by-step explanation:

We are told that the diagonal measures 7 inches.

We are also told that the length of the screen is 2.7 inches more than the width.

Let the length be L and width be W.

Thus, L = W + 2.7

Now, since length = W + 2.7 and width = W and diagonal = 7 inches, we can use pythagoras theorem to solve.

Thus;

W² + (W + 2.7)² = 7²

W² + W² + 5.4W + 7.29 = 49

2W² + 5.4W - 41.71 = 0

Using quadratic formula, we have;

W = [-5.4 ± √(5.4² - 4(2 × -41.71))]/(2 × 2)

W = [-5.4 ± √(362.84)]/4

W = -5.4/4 ± 19.05/4

W = (-1.35 + 4.7625) or (-1.35 - 4.7625)

W ≈ 3.4 inches or -6.1

W cannot be negative, thus, W = 3.4 inches

From earlier, we saw that L = W + 2.7

Thus,L = 3.4 + 2.7 = 6.1 inches

So, Length = 6.1 inches and Width = 3.4 inches

Answer:

1. -9

2. -6

3. -4

4. -14

Step-by-step explanation:

if you add a negative and a negative it is still a negative. when you have a number minus a negative, it can be positive or a negative. you change the -(- to a + this is what I call chop slash. then you do -8 + 2 = -6 because you are at -8 and then go to the right of the number line 2 spaces. numbers 1 and 4 have the same rules and numbers 2 and 3 have the same rules.

Step-by-step explanation:

(hog)(x) = h(g(x))

= h(3x + 7)

h(x) = x + 8

h(3x + 7) = 3x + 7 + 8

h(3x + 7) = 3x + 15

(hog)(x) = 3x + 15

Answer:

-50 feet

Step-by-step explanation:

The trout is swimming 30 ft below sea level,if it were above sea level it would be positive but since its below it is negative. It then swims 20 feet lower so it would be -50 as a short cut you can use in problems like this one is to ignore the sign's and add it regularly then add the sign after the equation is done.

Answer:

-50 is the answer

0.40 ___0.04

We are given with two decimal numbers. Compare the numbers and complete the blank by < or > or =

To compare the decimals , compare each digit from left to right

0 is equal to 0

4 is greater than 0

so we can say 0.40 is greater than 0.04

0.40 > 0.04

Both decimal numbers are not equal

Answer:

0.40 > 0.04

Step-by-step explanation:

First of all, your question is very clear. Excluding 0 is a needed restriction.

f(1) = 3*1 + 1 = 3 + 1 = 4

f(2) =3*2 + 1 = 6 + 1 = 7

f(3) = 3*3 + 1 = 9 + 1 = 10

f(4) = 4*3 + 1 = 12 + 1 = 13

Answer: B

Step-by-step explanation:

To find r, we need to use the formula to find slope. The formula is [tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]. Since we are given the coordinates and slope, we can plug them into the formula and solve for r.

[tex]\frac{2}{3} =\frac{3-5 }{r-4}[/tex]               [multiply both sides by r-4]

[tex]\frac{2r-8}{3}=3-5[/tex]        [subtract]

[tex]\frac{2r-8}{3}=-2[/tex]           [multiply both sides by 3]

[tex]2r-8=-6[/tex]        [add both sides by 8]

[tex]2r=2[/tex]                 [divide both sides by 2]

[tex]r=1[/tex]

Now that we found that r=1, we know that the answer is B.

Answer:  The numbers are 172  and 43

Step-by-step explanation:

We will represent the numbers by x and y  

where x is the positive number and y is the other number.

So x the positive number is 4 times the other number which could be represented by the equation x = 4y  

And the difference between x and y is 129  which could also be represented by the equation  x - y = 129  

Now use both equations to solve for y and x  

x = 4y  

x-y = 129   Substitute the value for x into the second equation

4y - y = 129

 3y = 129  

   y =  43  so we know that y is 43  and  x is 4 times it

x = 4(43)

x= 172  

So the numbers are 172 and 43 .

Check:

172 - 43 = 129

   129 = 129

Answer:

2.9 units

Step-by-step explanation:

Length of the radius = ½ of the distance between the two endpoints

Distance between (-2, 4) and (3, 1) using the formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] (-2, 4) = (x_1, y_1) [/tex]

[tex] (3, 1) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(3 - (-2))^2 + (1 - 4)^2} [/tex]

[tex] d = \sqrt{(5)^2 + (-3)^2} [/tex]

[tex] d = \sqrt{25 + 9} = \sqrt{34} [/tex]

[tex] d = 5.8 [/tex]

Length of radius = ½ of 5.8 = 2.9 units.

Postcard C is the same shape as the painting because they are in the same proportion.

It is defined as the law to prove that the two figures have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.

It is given that:

A museum sells postcards of famous paintings.

Applying similarity law that states: The ratio of the corresponding sides is in the same proportions.

In poster A:

5/30.25 = 5/25.25

1/6.05 = 1/5.05

In the poster B:

8/30.25 = 4/25.25

1/3.78 = 1/6.312

In poster C:

6.05/30.25 = 5.05/25.25

1/5 = 1/5 (they are in the same proportion)

Thus, postcard C is the same shape as the painting because they are in the same proportion.

An expression that is equivalent to 3(5x-4) is: D. 15x-12.

The distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a given numerical value or factor, the same output would be produced as when each addend is multiplied respectively by the numerical value or factor, and the products are added together.

Mathematically, the distributive property of multiplication is given by this expression:

a(b + c) = ab + ac.

By applying the distributive property of multiplication to the given expression, we have:

3(5x - 4) = 3(5x) - 3(4)

3(5x - 4) = 15x - 12

Therefore, the correct answer option is: D.) 15x - 12.
