Answer:
=10√5 or 22.36068 as a decimal
the ^ is to the power of
Step-by-step explanation:
2^2 x 5^3
=[tex]\sqrt{2^{2} 5^{3} }[/tex] (you don't need the x it just did not let me put it in otherwise)
apply the exponent rule 2^2 x 5^3= 5^2 x 5 = √2^2x5^2x5
√2^2x5^2x5= √2^2 √5^2 √5= √2^2√5^2√5
next, apply the radical rule
√2^2=2 =2√5^2 √5
√5^2=5 = 2x5√5
=10√5 which is also 22.36068 as a decimal

Kevin and christy both saved money for their class trip . Kevin saved the same amount each week . The total amount that Kevin saved at the end of every two weeks in shown in the table below .
Answer:
D. Christy saved $3 per week more than Kevin.
Step-by-step explanation:
We already know how much Christy saves per week, because of the equation y = 26x. She saves $26 per week.
To find Kevin's per week savings, divide y by x. I'll do (6, 138) as an example.
138 / 6
What multiple of 60 is closest to 138 without going over. That's 120.
138 - 120 = 18
Now we know the constant (k) is greater than 20.
18 / 6
6 goes into 18 three times.
20 + 3 = $23 per week.
$23/week is less than $26/week, so to say Kevin earned more than Christy in one week is wrong. As a result, A and C are out.
Now subtract 23 from 26 to get a $3 per week difference, which is D.

What are the values of m x and a

Step-by-step explanation:
I attached the picture with labels to can solve
In the 2 Δs ADE and ACF
∵ DE // CF
∴ m∠ADE = m∠ACF ⇒ corresponding angles
∴ m∠AED = m∠AFC ⇒ corresponding angles
→ By using the AA postulate of similarity
∴ The two triangles are similar
∴ Their corresponding sides have the same ratio
∴ [tex]\frac{AD}{AC}[/tex] = [tex]\frac{EA}{FA}[/tex] = [tex]\frac{DE}{CF}[/tex]
∵ AD = AB + BC + CD
∵ AB = 3, BC = 6, CD = x
∴ AD = 3 + 6 + x
∴ AD = 9 + x
∵ AC = AB + BC = 3 + 6
∴ AC = 9
∵ AE = AG + GF + FE
∵ AG = 4, GF = 8, FE = 4
∴ AE = 4 + 8 + 4
∴ AE = 16
∵ FA = AG + GF = 4 + 8
∴ FA = 12
∵ DE = 7 and CF = m
→ Substitute them in the ratio above
∴ [tex]\frac{9+x}{9}[/tex] = [tex]\frac{16}{12}[/tex] = [tex]\frac{7}{m}[/tex]
→ By using cross multiplication with the first 2 fractions
∵ 12 × (9 + x) = 9 × 16
∴ 12(9) + 12(x) = 144
∴ 108 + 12x = 144
→ Subtract 108 from both sides
∴ 108 - 108 + 12x = 144 - 108
∴ 12x = 36
→ Divide both sides by 12 to find x
∴ x = 3
→ By using cross multiplication with the second 2 fractions
∵ 16 × m = 12 × 7
∴ 16m = 84
→ Divide both sides by 16
∴ m = 5.25
In the 2 Δs ABG and ACF
∵ BG // CF
∴ m∠ABG = m∠ACF ⇒ Corresponding angles
∴ m∠AGB = m∠AFC ⇒ corresponding angles
→ By using the AA postulate of similarity
∴ The two triangles are similar
∴ Their corresponding sides have the same ratio
∴ [tex]\frac{AB}{AC}[/tex] = [tex]\frac{GA}{FA}[/tex] = [tex]\frac{BG}{CF}[/tex]
∵ AB = 3 and AC = 9
∵ GA = 4 and FA = 12
∵ BG = a and CF = m = 5.25
→ Substitute them in the ratio above
∴ [tex]\frac{3}{6}[/tex] = [tex]\frac{4}{12}[/tex] = [tex]\frac{a}{5.25}[/tex]
→ By using cross multiplication with the second 2 fractions
∵ 12 × a = 4 × 5.25
∴ 12a = 21
→ Divide both sides by 12 to find a
∴ a = 1.75

Step-by-step explanation:
Marcus purchase 3 pounds of apples in 4 pounds of strawberries for a total of $12.50 Shannon purchase 5 pounds of apples in 1 pound of strawberries for a total of $13.75 right and solve a system of equations that can be used to find the cost of 1 pound of apples in 1 pound of strawberries
Answer:
Step-by-step explanation:
1. 3x+4y=12.5
5x+1y=13.75
Answer:
1 pound of apple costs $2.50
1 pound of strawberries costs $1.25
Step-by-step explanation:
System of Equations
Let's define the following variables:
x = cost of 1 pound of apples
y = cost of 1 pound of strawberries
.........................................
Marcus purchased 3 pounds of apples and 4 pounds of strawberries for a total of $12.50. Thus:
3x + 4y = 12.50 [1]
Shannon purchased 5 pounds of apples and 1 pound of strawberries for a total of $13.75, thus:
5x + y = 13.75 [2]
We need to solve the system of the equations [1] and [2].
Solving for y in [2]:
y = 13.75 - 5x [3]
Substituting in [1]
3x + 4(13.75 - 5x) = 12.50
Operating:
3x + 55 - 20x = 12.50
-17x = -55 + 12.50 = -42.50
Dividing by -17:
x = -42.50/(-17)
x = 2.5
Substituting in [3]:
y = 13.75 - 5*2.5
y = 1.25
Solution:
1 pound of apple costs $2.50
1 pound of strawberries costs $1.25

PLEASE HELP! The question is in the attachment.
Answer:
x > 1
Step-by-step explanation:
15 - 1 = 14
The inequality is 15 - 1 < 14, but this is incorrect. 14 can not be less than 14. In order for the left side to be less than 14, the x value (currently representing 1) should be larger than what it currently is to make the statement true.
Therefore, x>1

Step-by-step explanation:Firstly set the argument in which (x² + 3) is Greater than 0 , to see where the expression is defined .
[tex]\bf \implies (x^2+3) > 0 [/tex]
Now ,let's simplify this
[tex]\bf \implies (x^2+3)>0 \\\\\bf\implies x^2 > 0 - 3 \\\\\bf\implies\boxed{\red{\bf x^2 > (-3) }}[/tex]
Since the left side has even Power , it is always positive for all real numbers.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Karl’s watering system rotates at a constant. One complete rotation takes 72 hours. Following the circular motion of the watering system, how many degrees was watered after TWO DAYS?
Answer:
After two days, 240 degrees was water.
Step-by-step explanation:
24 hours = 1 day
72 hr/24 hr = 3 days
Therefore, one full rotation takes 3 days.
1 rotation = 360 degrees
360 degrees/ 3 days = 120 degrees per day
120 degrees x 2 days = 240 degrees
240 degrees was watered after two days

Triangle ABC is rotated 180 degrees around point B and then dilated to form triangle DBE as shown. Which postulate or theorem establishes that the triangles are similar? AA Similarity SSS Similarity SAS Similarity ASA Similarity
Answer:
AAA Similarity
Step-by-step explanation:
Given:
Triangles ABC and DBE
Required
Which postulate shows ABC and DBE similarity
From the question, we understand that the following transformation were done on ABC
RotationDilationIt should be noted that, when a triangle (e.g. triangle ABC) is rotated, the length of the sides and angle measurements remain unchanged.
However, when this triangle is dilated, the sides of the triangle change, but the angles remain unchanged.
Having said that,
When ABC is rotated and dilated to form DBE, we have:
[tex]\angle A = \angle D = a[/tex]
[tex]\angle B = \angle B = b[/tex]
[tex]\angle C = \angle E = c[/tex]
[See Attachment]
Hence, the postulate that answers this question is AAA (Angle-Angle-Angle).
