On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday

Finger [1]

Answer: $-8^{\circ}C$

Step-by-step explanation:

Given

The temperature on Tuesday is $1^{\circ}C$

Temperature drops to $-2^{\circ}C$ on Wednesday

Net drop in temperature $1-(-2)=3^{\circ}C$

The temperature drops twice from Wednesday to Thursday

$\Delta T=2\times 3=6^{\circ}C$

Temperature on Thursday

$\Rightarrow -2-6=-8^{\circ}C$

1. The ratio of the number of boys to the number of girls on the swim team

Papessa [141]

Answer:

Step-by-step explanation:

Sum the parts of the ratio 4 + 2 = 6 parts

Divide 24 by 6 to find the value of one part of the ratio

24 ÷ 6 = 4 ← value of 1 part, thus

number of boys = 4 × 4 = 16

number of girls = 2 × 4 = 8

Hence there are 8 more boys than girls

Give an example of a set of five different numbers whose mean is 290

leva [86]

Answer:

200,300,290,320,340

Step-by-step explanation:

If the mean of five numbers = 290

Then the total sum of the five numbers should be= 290*5

= 1450

an example of a set of five different numbers whose mean is 290

= 200,300,290,320,340

Summation of the above

=( 200+300+290+320+340)

= 1450

So the above set of numbers is a good example of a set of five different numbers whose mean is 290

What is the inequality?

crimeas [40]

Answer:

$y\leq \frac{1}{2}x+2$

Step-by-step explanation:

we know that

The solution of the inequality is the shaded area below the solid line (the inequality is of the form $y\leq mx+b$ )

The y-intercept of the solid line is (0,2)

The x-intercept of the solid line is (-4,0)

The slope of the solid line is

$m=(0-2)/(-4-0)=\frac{1}{2}$

The equation of the solid line is $y=\frac{1}{2}x+2$

therefore

The linear inequality represented by the graph is

$y\leq \frac{1}{2}x+2$
