Answer:

140

Step-by-step explanation:

Let the number = x

Hence, the expression can be written has:

0.4 of x = 56

0.4x = 56

Divide both sides by 0.4

0.4x / 0.4 = 56 / 0.4

x = 140

Hence, 56 is 0.4 of 140

which number in front of the decimal if the biggest

Answer:

87.4°

Step-by-step explanation:

(3x + 8) + (3x + 18) + (7x + 9) = 180

3x + 8 + 3x + 18 + 7x + 9 = 180

add the common numbers

13x + 35 = 180

subtract 35

13x = 145

divide 13

x = 11.2

then plug it back in to m<3

7(11.2) + 9

78.4 + 9

= 87.4°

Answer:

AA similarity

Step-by-step explanation:

Your question is not well presented.

See attachment

Given

Triangles ABC and DBE

Required

Which postulate supports the similarities of ABC and DBE

At the first transformation (180 degrees rotation) both triangles maintain SSS and AAA relationships. i.e Side-Side-Side and Angle-Angle-Angle

This is so because rotations do not alter the side lengths; neither does it alter the angles.

When the second transformation (dilation) takes place, the lengths of both triangles ABC and DBE become different because dilation alters side lengths.

However, angle measurements remain unaltered.

Hence, AAA similarity answers the question

Answer:

D

Step-by-step explanation:

This question is written very poorly because it is hard to know what x represents, as well as the end equation. I have come to the conclusion that x represents the amount of days and the end equation represents the exact same equation given (as it asks to rewrite the equation)

So, it is obvious that only one equation matches the one given -- as (1.03)^7 is approximately 1.23, which is close enough to 1.25 (compared to the other options), D is our answer

A and B have both 1.25^7 = around 4.77 (480% ish), and C has 1.03^x, which is not very close to 1.25

The growth of the weed is shown by each day will be f(x) = 197(1.03)⁷ˣ. Then the correct option is D.

Consider the function:

y = a (1 ± r)ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

Initially, there were only 197 weeds at the park. The weeds grew at a rate of 25% each week. The following function represents the weekly weed growth:

f(x) = 197(1.25)ˣ

If the growth of the weed is shown by each day will be given as,

r = 0.25 / 7

r = 0.03

Then the function is given as,

f(x) = 197(1.03)⁷ˣ

The growth of the weed is shown by each day will be f(x) = 197(1.03)⁷ˣ. Then the correct option is D.

Let me know if I'm wrong.

Answer:

x = 26, y = 19

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{ST}{NP}[/tex] = [tex]\frac{RS}{MN}[/tex] , substitute values

[tex]\frac{x}{13}[/tex] = [tex]\frac{32}{16}[/tex] = 2 ( multiply both sides by 13 )

x = 26

and

[tex]\frac{MP}{RT}[/tex] = [tex]\frac{MN}{RS}[/tex] , substitute values

[tex]\frac{y}{38}[/tex] = [tex]\frac{16}{32}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 38 ( divide both sides by 2 )

y = 19

Answer: i think its 4

Step-by-step explanation:

answer: 1

step-by-step explanation:  n + 8 = 9

therefore 9-8 = 1

The solution to the equation n+ 8 = 9 is 1 from the set {0,1,17,72} n = 1 satisfy the provided equation.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a linear function in terms of n:

n + 8 = 9

Subtract 8 both side:

n + 8 – 8 = 9 – 8

n = 1

From the set, we can see the element 1 is the solution to the given equation.

Thus, the solution to the equation n+ 8 = 9 is 1 from the set {0,1,17,72} n = 1 satisfy the provided equation.

Husfivhuisfhvkusdhvkufadhvkudshfukdahf

Step-by-step explanation:

Answer:

∠A =  115°

∠B =  65°

∠C =  115°

∠D =  65°

Step-by-step explanation:

The figure given is of parallelogram.

We need to find measure of each interior angle.

We are given:

∠A = (2x-15)°

∠B = x°

∠C = (2x-15)°

∠D = x°

We need to find measure of ∠A , ∠B, ∠C, ∠D

We know that sum of all angles of parallelogram = 360°

So, we can write: ∠A +∠B+ ∠C+ ∠D = 360°

Now putting their values and finding value of x first:

[tex]2x-15+x+2x-15+x=360\\Combining\:like\:terms:\\2x+x+2x+x-15-15=360\\6x-30=360\\6x=360+30\\6x=390\\x=\frac{390}{6}\\x=65[/tex]

So, we get x= 65

Now finding measure of each angle:

∠A = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠B = x° = 65°

∠C = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠D = x°= 65°

Answer is:

∠A =  115°

∠B =  65°

∠C =  115°

∠D =  65°
