the morning and went to -13°C at noon. It stayed at that temperature for six
hours and then rose 7°C. Which ADDITION expression shows the change in
temperature

Answer:Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Answer:

No.

Step-by-step explanation:

For polygon PQRST to be considered a scaled copy of polygon ABCDE, it means every segments of polygon ABCDE were increased proportionally by a scale factor.

The segments in polygon PQRST were not gotten using the same scale factor, hence, it is not a scaled copy of the original polygon, ABCDE.

Segment CD = 2 units, it corresponds to segment RS = 4 units. Scale factor = RS/CD = 4/2 = 2

Segment BC = 1 unit, it corresponds to segment QR = 1 unit. Scale factor = QR/BC = 1/1 = 1 units.

Varying scale factor shows polygon PQRST is not a scaled copy of polygon ABCDE.

Answer:

An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.

Step-by-step explanation:

That's what I think because the Basset Hound is 13.8 in. in height right? So he's two inches taller if we round up both numbers. Basset hound would be 14 and welsh corgi would be 11....................okay im not sure i give up but it's either

"An adult Welsh Corgi is always going to be shorter than an adult Basset Hound."

"Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

whichever just not the other ones good luck!

Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

Mean is actually the average of all the observations.

Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

of a data set is the average distance between each data value and the mean.

According to the problem,

Here we can say, the average height of Basset hounds is 13.8 and is highly dispersed in comparison to Welsh Corgis

So, we can say Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

Answer: C=(44,29).

Step-by-step explanation:

The given points are A = (-4 , -7)  and B = (12 , 5).

It is given that Point B is 1/3 of the way from A to C.

AB:AC=1:3

AB:BC=AB:(AC-AB)=1:(3-1)=1:2

It means point B divides the line segment AC in 1:2.

Let coordinates of C are (a,b).

Section formula: If a point divides a line segment in m:n, then

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Using section formula, we get

[tex]B=\left(\dfrac{1(a)+2(-4)}{1+2},\dfrac{1(b)+2(-7)}{1+2}\right)[/tex]

[tex](12,5)=\left(\dfrac{a-8}{3},\dfrac{b-14}{3}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{a-8}{3}=12[/tex]

[tex]a-8=36[/tex]

[tex]a=36+8[/tex]

[tex]a=44[/tex]

[tex]\dfrac{b-14}{3}=5[/tex]

[tex]b-14=15[/tex]

[tex]b=15+14[/tex]

[tex]b=29[/tex]

Therefore, the coordinates of C are (44,29).

Answer:

AB

A ray has one endpoint and the rest is a line, so AB would be the only answer that would make sense in this situation (because it's starting from A and B is a point on the ray).

Answer:

4 bowls

Step-by-step explanation:

Conversion rate :

1 liquid pint = 16 fluid ounces

From the question, we are told that :

4 fluid ounces of bubble mix = 1 bowl

16 fluid ounces of bubble mix(1 liquid pint) = y bowl

Cross Multiply

4 fluid ounces × y bowl = 16 fluid ounces × 1bowl

y bowl = 16 fluid ounces × 1bowl/4 fluid ounces

= 4 bowls

Therefore, he can fill 4 bowls with 1 pint of bubble mix

Answer:

The humpback whales are 37 times bigger than the krills they eat

Step-by-step explanation:

In this question, we are interested in knowing how much bigger are humpback whales compared to krill.

what is simply happening here is to divide the weight of the humpback whales by the weight of the krills.

From the question, weight of humpback whales = 8 * 10^4 while the weight of the krills are 2.1875 * 10^3

So the number of times the humpback whales are bigger is;

(8 * 10^4)/(2.1875 * 10^3) = 36.57 which are approximately 37 times bigger

Answer:

perpendicular

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x = y - 5 ( add 5 to both sides )

3x + 5 = y ← in slope- intercept form

with slope m = 3

------------------------------------------------

9y + 4x = x - 9 ( subtract 4x from both sides )

9y = - 3x - 9 ( divide all terms by 9 )

y = - [tex]\frac{1}{3}[/tex] x - 1 ← in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

-----------------------------------------------

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

Thus

the slopes are not equal, thus not parallel lines.

3 × - [tex]\frac{1}{3}[/tex] = - 1 , hence lines are perpendicular

Answer:

yes

-2(2-2x)-4(x+5) is less than or equal to -24

-2(2-2x)-4(x+5) <_ -24        Divide the expression by the #'s outside the ()

2-2x+x+5>_-3                     This is the quotient from dividing it by -8 (-2 and -4)
