The temperatures recorded were -18.072 Celcius and -11.927 Celcius.

Step-by-step explanation:

Step 1; Assume one of the temperatures is given a value of x. One of the measurements that Mark measured was 2/3 of the other. So if one value is x then the other is 2/3x.

Step 2; Now we equate the two temperatures to find their values. it is given their sum is -30 Celcius so the sum of x and 2/3x is -30. The equation is as follows

x + 2/3 x = -30, x + 0.666x = -30, 1.666x = -30, x= -18.072

Step 3; After solving x we have found the value of one of the temperatures. The other can be found by multiplying 2/3 with x i.e. 2/3 * -18.072 which equals -11.927. So temperatures are -18.072 Celcius and -11.927 Celcius.

5) Phillip earns $11.25 per hour. During Week 1, he worked h hours. During Week 2, he worked 8
Naddik [55]

Answer:

2,160 Hours

Step-by-step explanation:

Ok so usual i would split $540 in half so a number multiplied by two would end up as 540, and i got 270. So since each week we know Phillip earned $270 and $11.25 a hour, we can divide 270 by 11.25, which gives us $24, so that means h = 24, but on week 2 it says Phillip worked 8 hours more on week 2, so that gives us a equation of 8 x 11.25, which comes out to 90, so now we can move on to our final equation, 90 x 24, which equals 2160. Im so sorry if this is wrong

Helen's house is located on a rectangular lot that is1 1-8 miles by 9/10 mile.Estimate the distance around the lot
klemol [59]

Answer: The distance around the lot is given by

4\frac{1}{20}\ miles

Step-by-step explanation:

Since we have given that

Length of rectangular lot is given by

1\frac{1}{8}\\\\=\frac{9}{8}\ miles

Width of rectangular lot is given by

\frac{9}{10}\ mile

We need to find the distance around the lot.

As we know the formula for "Perimeter of rectangle":

Perimeter=2(Length+Width)\\\\Perimeter=2(\frac{9}{8}+\frac{9}{10})\\\\Perimeter=2(\frac{45+36}{40})\\\\Perimeter=2\times \frac{81}{40}\\\\Perimeter=\frac{81}{20}\\\\Perimeter=4\frac{1}{20}\ miles

Hence, the distance around the lot is given by

4\frac{1}{20}\ miles
