Answers:
EG = 26 unitsangle IFG = 40 degreesInput the numbers only.
=========================================================
Explanation:
In any rectangle the diagonals are the same length. Also, the diagonals cut each other in half (aka bisect).
This means EI and FI are the same length
EI = FI
4x+5 = 6x+1
4x-6x = 1-5
-2x = -4
x = -4/(-2)
x = 2
This then leads to
EI = 4x+5 = 4(2)+5 = 13FI = 6x+1 = 6(2)+1 = 13Both are 13 units long to help confirm we have the correct x value.
If EI = 13, then EG = 2*EI = 2*13 = 26 since EG is twice as long as EI. This goes back to the fact that the diagonals cut each other in half.
-------------
If angle EIH is 100 degrees, then so is angle FIG (they are vertical angles).
Focus on triangle FIG. We just found that angle i = 100. This triangle is isosceles with FI = IG being the two equal sides. The angles opposite these congruent sides are angles F and G. Let's call them x for now.
So we have
i = 100F = xG = xThe three angles of this triangle add to 180
F+I+G = 180
x+100+x = 180
2x+100 = 180
2x = 180-100
2x = 80
x = 80/2
x = 40
So angle F, of triangle FIG, is 40 degrees
This is the same as saying angle IFG is 40 degrees.
Answer:
EG = 26 units
angle IFG = 40 degrees

If BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6, what are the values of x and AC?
Answer: x=7 and AC = 44 unuts.
Step-by-step explanation:
We know that the diagonals of a parallelogram bisect each other. (i)
Here in parallelogram ABCD , AC and Bd are diagonals intersecting at E.
BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6
Using (i)
[tex]BE=\dfrac{BD}{2}\\\\2x+2=\dfrac{5x-3}{2}\\\\ 2(2x+2)=5x-3\\\\ 4x+4= 5x-3\\\\ 5x-4x=4+3\\\\ x= 7[/tex]
Now , AE = 4(7)-6 = 28-6 = 22
AC =2 AE = 2 (22) =44 units.
Hence, x=7 and AC = 44 unuts.

Write 15% as a fraction in simplest form:
Answer:
3/20
Step-by-step explanation:
15 / 100
divide both the numerator and denominator by 5: 3 / 20
Answer:
3/20 is it's simplest form.
Step-by-step explanation:
How can we solve this?
we know we can simplify this if we can divide the numerator and denominator by the same number.15% is equal to 15/100.
15 divided by 5 equals 3.100 divided by 5 equals 20.Therefore, 15/100 can be simplified to 3/20.

Chloe compares the growth of plant species A and B. Part A What do the box plots tell you about the growth of a typical plant of each species? Choose the correct response. Plant B typically grows 1 cm taller than Plant A, since the range for Plant B is 1 cm greater. Plant B typically grows 1 cm taller than Plant A, since the IQR for Plant B is 1 cm greater. Plant A typically grows 1 cm taller than Plant B, since the median for Plant A is 1 cm greater. Plant A typically grows 1 cm taller than Plant B, since the mean for Plant A is 1 cm greater.
Answer:
Type A Type B
Median 52 grams 52 grams
Lower Quartile 49 grams 51 grams
Upper Quartile 57 grams 54 grams
Range 14 grams 8 grams
Interquartile Range 8 grams 3 grams
From this table we can see that both types of tomato have the same average mass because their medians are the same.
Comparing the medians and interquartile ranges shows that there is far more variation in the masses of the type A tomatoes, which means that the masses of type B are more consistent than those of type A.
However, comparing the two box and whisker plots, and the upper quartiles, shows that type A tomatoes will generally have a larger mass than those of type B.
Nevertheless, there will be some type A tomatoes that are lighter than any of type B.
Taking all this together, the gardener would be best advised to plant type A tomatoes in future as he is likely to get a better yield from them than from type B.

Evaluate (98 x 102) by using suitable identities.
Answer:
The answer is 9996
Step-by-step explanation:
Using the identity (x+a)(x+b) = x ^2 +(a+b)x+ab
Writing 102 as 100+2 and 98 as 100−2
Hence (100+2)(100−2) = 100 ^2 +[2+(−2)]100+(2)(−2)
= 10000+(0)100−4
= 9996
The answer is 9996
Answer:
9996
Step-by-step explanation:
by using suitable identities ;
(98) × (102)(100 - 2) × (100 + 2)10000 - 49996identity used here is :
[tex](a + b) \times (a - b) = (a {}^{2} - b {}^{2} )[/tex]

If 2 > -a, then _____
Answer:
-2 < a
Step-by-step explanation:
Because each roll has six possible even values (2, 4, 6, 8, 10, and 12) and only five possible odd values (3, 5, 7, 9, and 11), the dice should show even values more often than odd values. Do you agree with this statement? Explain.
