Answer:

13°C

Step-by-step explanation:

The number of hours that the temperature fluctuates is irrelevant to the problem.

This problem is asking how many degrees did the temperature increase in order to go back to 30°C after being decreased by 13°C.

Find the new temperature after it decreased:

If the temperature after decreasing is 17°C, it needs the same amount it was decreased by to go back to 30°C.

Therefore, the temperature subsequently increased by 13°C to go back to 30°C after being decreased by 13°C.

Answer:

the number of additional she needed is 135

Step-by-step explanation:

The computation is shown below:

GIven that

40 flowers of 16%

So for 100% it would be

= 40 ×100 ÷ 16

= 250

Now she needs to make is

= 70% - 16%

= 54%

Now the additional would be

= 250 × 54%

= 135

Hence, the number of additional she needed is 135

Answer:

f(x) = -x + 2x + 5

is odd since f(x) = -5

f(x) = x + 8x

is neither because f(x) = 0

f(x) = -7x² + 5

is odd since f(x) = √5/7

f(x) = 5x + 3x? – 7x + 1

is odd

Answer:

x² + y² = 841

Step-by-step explanation:

Midpoint of diameter is a center of a circle.

Coordinates of midpoint are

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )

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

Equation of a circle with center at (h, k) and radius "r" is (x - h)² + (y - k)² = r²

~~~~~~~~~~

C(20, 21)

D(- 20, 21)

( [tex]\frac{-20+20}{2}[/tex] , [tex]\frac{-21+21}{2}[/tex] ) = (0, 0)

d = [tex]\sqrt{(-20-20)^2 +(21+21)^2}[/tex] = √3364 = 58

r = [tex]\frac{d}{2}[/tex] = 29

x² + y² = 29²

x² + y² = 841

Answer:1. 1.0 1.0 1.4

Step-by-step explanation:

The  length of the sides are given by the 45°–45°–90° triangle theorem.

Correct responses:

The 45°–45°–90° triangle theorem states that the ratio of the lengths of

the sides of triangles having interior angles of 45°, 45°, 90° is 1 : 1 : √2

The lengths of the legs of an isosceles triangle are equal.

The legs of the given isosceles right triangle are AB and AC

Therefore;

AB = AC

Taking the lengths of AB as 1 unit, we have;

AB = 1 = AC

According to Pythagorean theorem, we have;

[tex]\overline{BC}^2 = \mathbf{\overline{AB}^2 + \overline{AC}^2}[/tex]

Which gives;

[tex]\overline{BC}^2 = 1^2 + 1^2 = \mathbf{ 2}[/tex]

Therefore;

BC = √2

Therefore, by setting the length of AB = AC = 1, we have;

The above values are in the ratio 1 : 1 : √2, which corresponds with the

45°-45°-90° triangle theorem.

Answer:

the single decimal multiplier is 1.0058

Step-by-step explanation:

Let us have 100

Decreasing by 6% will be

100 - 0.06(100)

= 94

Increasing by 7%

= 94 + 0.07(94)

= 100.58

So

to get the single decimal multiplier,

we have 100.58/100 = 1.0058

Answer:

Step 1, all the exponents are increased by 4

Step-by-step explanation:

The first incorrect step occurred in Step 1, where all the exponents were increased by 4.

This is mathematically incorrect due to exponential rules. When distributing exponents inside parentheses, we have to multiply the existing exponents inside the parentheses by the exponent outside the parentheses.

For example, (x²)³ is not x²⁺³, but rather, x⁽²⁾⁽³⁾.

We multiply the exponents instead of adding them together.

Therefore, the correct Step 1 should multiply all the variables' exponents by 4.

Steps 2 and 3 are correct since we do add the exponents when multiplying exponents with the same base, and we do subtract exponents with the same base when dividing.  

Answer: left one is no solution and right one is infinite solutions

explanation: the left one the lines don’t touch at all which has no solution and the right one means that both lines are on top of each other

In the first graph, there are ''No solution.''

In the second graph, there are ''Infinitely solution.''

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Now,

For the first graph;

In this graph we can see that there are two parallel lines.

We know that two parallel lines never intersect.

Therefore, we never get any common coordinate for this.

Thus, This system has ''No solutions.''

For the second graph;

There is a single straight line is given.

We know that each point be the solution of this line and a line contains infinitely many pints.

Thus, it has ''infinitely many solutions.''

Hence, The first graph is shows the ''No solution'' and the second graph is shown the ''infinitely many solutions.''

4x + y = 6 => 8x + 2y = 12.

8x + 2y = 12

+ (-5x - 2y = -3)

=> 3x = 9, x = 3.

Therefore 4(3) + y = 6, 12 + y = 6, y = -6.

The solutions are x = 3 and y = -6.
