Answer:
Your answer is in the screenshot! :)
Step-by-step explanation:
1. Solve for yy in y+7x=50y+7x=50. y=50-7x
y=50−7x
2. Substitute y=50-7xy=50−7x into 14x-5y=-2814x−5y=−28. 49x-250=-28
49x−250=−28
3. Solve for xx in 49x-250=-2849x−250=−28. x=\frac{222}{49}
x= 49 222
4. Substitute x=\frac{222}{49}x= 49 222 into y=50-7xy=50−7x.
y=\frac{128}{7} y= 7 128
5. Therefore, \begin{aligned}&x=\frac{222}{49}\\&y=\frac{128}{7}\end{aligned} x= 49 222 y= 7 128 Hope this helped!! :))
Choose the correct comparison for the numbers below.
0.85, 3/4, 91%
a. 3/4 > 0.85 > 91%
c. 91% > 3/4 > 0.85
d. 0.85 < 3/4 < 91%
Answer:
A
Step-by-step explanation:
In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.
The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.
Since 0.85 is already in decimal form, leave it as it is.
3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:
[tex]\frac{3}{4} * \frac{25}{25} = \frac{75}{100}[/tex]
Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.
91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.
Now that you can see the numbers, just rearrange them from least to greatest
0.75<0.85<0.91
equal to A
1) Jayden states that based on the Congruent Supplements Theorem, if
mZ1 +mZ2 = 90° and if mZ1 +mZ3 = 90°, then 22 =23. What is
the error in Jayden's reasoning?
Answer:
The congruent supplements theorem states that 2 angles are supplementary if they add up to 180 degrees, not 90 degrees.
He should have stated the complimentary theorem instead.
Step-by-step explanation:
The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.
Given:
∠1 +∠2 = 90° and if ∠1 +∠3 = 90°, then ∠2 =∠3
To find:
The error in Jayden's reasoning
Solution:
According to Congruent Supplements Theorem, the sum of supplementary angles is equal to 180°, not 90°.
[tex]\angle 1 +\angle 2 = 180^o\\\angle 1 +\angle 3 = 180^o\\\text{From this, we can conclude that}:\\\angle 2 = \angle 3[/tex]
The error in Jayden's reasoning was 90°.
The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.

Step-by-step explanation:
(1)
Calculate the circumference (C) of the wheel
C = πd (d is the diameter )
= 3.14 × 8 = 25.12 cm
Now divide the distance travelled by the circumference.
times rotated = 12560 ÷ 25.12 ≈ 500
----------------------------------------------------------------
(2)
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Find r by using the circumference (C)
2πr = 50.24 ( divide both sides by 2π )
r = 50.24 ÷ 6.28 = 8 , then
A = 3.14 × 8² = 3.14 × 64 ≈ 200.96 ft² ( student 3 )
-----------------------------------------------------------------
(3)
C = πd = 3.14 × 30 = 94.2 ≈ 94 m

A. -4
B. 4
C. -1/4
D. 1/4
Answer:
D
Step-by-step explanation.
The slope is the change in y over the change in x. If you look at the change in y, it goes from 2 to 3, and 3-2=1. If you look at the change in x, it goes from -1 to 3, and 3-(-1)=4 (if you subtract a negative it adds the number instead). IF you put the change in y over the change in x, you get 1/4, which is D

Eliminate y-term
[tex](x + 2x) + (4y - 4y) = 9 - 6 \\ 3x = 3 \\ x = \frac{3}{3} \\ x = 1[/tex]
Substitute x = 1 in any given equations.
I choose to substitute in the first equation.
[tex]x + 4y = 9 \\ 1 + 4y = 9 \\ 4y = 9 - 1 \\ 4y = 8 \\ y = \frac{8}{4} \\ y = 2[/tex]
Answer Check
Substitute both x-value and y-value in any given equations.
[tex]x + 4y = 9 \\ 1 + 4(2) = 9 \\ 1 + 8 = 9 \\ 9 = 9[/tex]
The first equation is true. However, we have to check the second equation as well. (Although the first true equarion has already raised the high possibility of right answer.)
[tex]2x - 4y = - 6 \\ 2(1) - 4(2) = - 6 \\ 2 - 8 = - 6 \\ - 6 = - 6[/tex]
Both equations are true for (1,2). Thus the answer is (1,2)
An Ice Cream Factory makes 3:1 tubs of ice cream to boxes of ice cream bars. If the factory makes 165 tubs of ice cream in a day, how many boxes of ice cream bars were made?
Answer:
55 boxes of ice cream
Step-by-step explanation:
Tubs of ice cream : boxes of ice cream = 3 : 1
If the factory makes 165 tubs of ice cream in a day, how many boxes of ice cream bars were made?
Boxes of ice cream made in a day = x
Tubs of ice cream : boxes of ice cream = 165 : x
Equate both ratios to find x
3 : 1 = 165 : x
3/1 = 165/x
Cross product
3 * x = 1 * 165
3x = 165
x = 165/3
x = 55
Boxes of ice cream made in a day = 55
Which choices are real numbers. Check all that apply. A. (-1024)^1/4. B. (-131072)^1/16. C. (-256)^1/9. D. (-531441)^1/13
Answer:
B and C
Step-by-step explanation:
Because it is raised to the ^Power of 13. This choice makes the most sense.
The real numbers are [tex](-256)^{1/9}[/tex] and [tex](-531441)^{1/13}[/tex]. Then the correct options are C and D.
What is a real number?All the numbers are real number.
If the number is having iota (i), then the number becomes complex number.
A. [tex](-1024)^{1/4} = 4 * (-2^2)^{1/4} = 4\sqrt2 \iota[/tex]
B. [tex](-131072)^{1/16} = 2*(-2)^{1/16} = 2 \sqrt[16]{2} \iota[/tex]
C. [tex](-256)^{1/9} = -1.85[/tex]
D. [tex](-531441)^{1/13} = -2.76[/tex]
Then the real numbers are [tex](-256)^{1/9}[/tex] and [tex](-531441)^{1/13}[/tex].
Then the correct options are C and D.

The population of a small town increased 23% from its population in 2000 to its population in 2003. If the population of the town in 2000 was 25,314, what was its population in 2003?
Answer:
31136
Step-by-step explanation:
To find the how much an number increased by a percent. Divide the percent by 100. 23/100=0.23.
Then multiply 0.23 by the original number which is 25,314. Which gives us about 5822.
Then since it INCREASED, we are going to add that number it increased to the original. 25314+5822= 31136.
Answer:
Good Luck, hope it helps:)
Step-by-step explanation:
23% of 25,314 = 25,314 x .23 = 5822 then add that to the original population. 25,314 + 5,822 = 31,136

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1LaTeX: \frac{3}{5}3 5 doors. How many liters of paint are needed for 1 door?
Answer:
1 1/4 liters of paint
Step-by-step explanation:
Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1LaTeX: \frac{3}{5}3 5 doors. How many liters of paint are needed for 1 door?
From the above question, we can deduce that:
2 liters of paint covers 1 3/5 doors
Hence:
1 3/5 doors = 2 liters of paint
1 door = x liters of paint
Cross Multiply
1 3/5 doors × x liters = 2 liters × 1 door
x liters = 2 liters × 1 door/ 1 3/5 doors
x liters = 2 ÷ 1 3/5
x liters = 2 ÷ 8/5
x liters = 2 × 5/8
x liters = 5/4 liters
x liters = 1 1/4 liters of paint
Hence: 1 1/4 liters of paint is needed for 1 door

The value of fraction will be 1/3.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
The expression is,
''A fraction of 60 is 20.''
Now,
Let the value of fraction = x
So, We can formulate;
⇒ x of 60 = 20
⇒ x × 60 = 20
⇒ x = 20/60
⇒ x = 2/6
⇒ x = 1/3
Thus, The value of fraction = 1/3
