Answer:
the coordinate of B is (-1;1)
Answer: 1/4, 4/7, 5/8
Step-by-step explanation: There are three ways:
1. <u>Convert each to a decimal: </u>
1/4 = 0.25
4/7 = 0.571
5/8 = 0.625
2. <u>Convert to a common denominator:</u>
It looks like we can multiply each by a whole number that will result in a denominator of 56:
1/4 *(14/14) = 14/56
4/7*(7/7) = 35/56
5/8 *(8/8) = 32/56
Now they can be directly compared to get the answer.
3. <u>Estimate the values. </u>
5/8 is clearly larger than 1/4. 4/7 is somewhere in between. Therefore, 1/4, 4/7, 5/8
Answer:
The sum of all the sides to this quadrilateral will equal a total of 20 inches, so you set up the equation:
2 + 2x + 7 + x + 2 = 20
Solve for x by combining like terms;
(2 + 7 + 2) + (2x + x) = 20
Which simplifies to;
11 + 3x = 20
Get rid of constants;
-11 -11
3x = 9
Isolate x by getting rid of it's coefficient;
/3 /3
<u>x = 3</u>
Now, to find the length of PQ, we plug in the value of x(3) into the equation that contains the line PQ.
x + 2
<u>3</u> + 2
= <u>5 inches.</u>
Now, to find the length of RS, we plug in the value of x(3) into the equation that contains the line RS.
2x
2(3)
= <u>6 inches.</u>
Answer:
y=3. (-1)-1
y= -3-1
y= -4
Step-by-step explanation:
<span>Dayson has 1 m2 of wrapping paper, which is 10000 cm2:
1 m = 100 cm
1 m^2 = (100 cm)^2
</span>1 m^2 = 10000 cm^2
<span>The package has a surface area of cm2:
A = 2*(50*20) + </span>2*(50*18) + 2*(18*20)
A = <span>
<span>4520 cm^2
</span></span>The area of the package is less than the area of the wrapping paper (4520 cm^2 < 10000 cm^2<span>). So, Dayson cover the package with the wrapping paper.</span>
