Answer:
28 and 49 are the two numbers whose sum is 77.
Step-by-step explanation:
19.87 but there’s a 20% discount what’s the answer now?
19.87 = 100%
If you divide both sides by ten, you would get what ten percent is.
1.987 = 10%
Multiply this by two to get 20%.
3.974 = 20%
Minus twenty percent from the original amount.
18.87 minus 3.974 = 15.886 after the discount.

An advertising flyer shows address labels as 4.3 cm by 1.2 cm. The ratio of the flyer label to the actual label is 2:3. What are the dimensions of the actual address labels?
Answer:
6.45 cm by 1.8 cm
Step-by-step explanation:
Ratio of label to actual measurement ; 2 : 3
For a flyer label size of 4.3
Actual label size equals :
(Flyer ratio / total ratio) * total size = flyer size
2/5 * x = 4.3
2x / 5 = 4.3
2x = 21.5
x = 21.5 / 2
x = 10.75
Actual size =. 10.75 - 4.3 = 6.45 cm
2/5 * x = 1.2
2x / 5 = 1.2
2x = 6
x = 6 / 2
x = 3
Actual size = 3 - 1.2 = 1.8 cm
6.45 cm by 1.8 cm

Ava is in a hot air balloon that has just taken off and is floating above its launching point. Mary is standing on the ground 4 meter away from the launching point. If ava and mary are 5 meters apart, how high up is ava ?
Answer:
Ava's altitude is 3 meters.
Step-by-step explanation:
The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.
So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]
25 = 16 + [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 25 - 16
= 9
x = [tex]\sqrt{9}[/tex]
= 3
x = 3 meters
Thus, Ava's altitude is 3 meters.
A forest covers 58,000 acres. A survey finds that 0.7% of the forest is old-growth trees. How many acres of old-growth trees are there?
Answer:
406
Step-by-step explanation:
0.7 % / 100 = 0.007
58000 * 0.007 = 406 acres
What is the perimeter of a rectangle with a length of 6cm and a width of
5cm?
Answer:
perimeter = 22 cm
Step-by-step explanation:
perimeter = 2(L + W) = 2(6 + 5) = 22 cm
Answer:
22cm
Step-by-step explanation:
P=2(l+b)
so length (l)=6cm
width (b)=5 cm

Matti has one more pencil than Chang-Lin. Renaldo had three times as many as Chang-Lin, and one more than Jorge. Jorge has 5 pencils, how many pencils does Matti Have?
Answer:Matti has 3pencils
Step-by-step explanation:
Given that Jorge has 5pencils
Renaldo has 1more than Jorge that means ,he has 5 +1=6pencils
But also
Renaldo =3Chang-Lin
6==3Chang-Lin
Chang-Lin = 6/3 =2
Since Chang-Lin has 2, Matti having 1more I than Chang-Lin will have 2+1=3pemcils
I will greatly appreciate if you can solve this question!
Answer: The answer would be B
Write out the equation in slope-intercept form:
y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)
Subtract -5/3 from both sides of the equation:
y+5/3x=6
Subtract 6 from both sides:
y+5/3x-6=0
Multiply both sides by 3 to get rid of the fraction:
3y+5x-18=0
Then arrange the numbers to x and y are on one side by itself:
3y+5x=18
And that's your answer!
Hope this helped you!

~AH1807Answer:
[tex](10x + 9 {)}^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.
[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]
2) Use square sum: ( a + b )² = a² + 2ab + b².
[tex](10x + 9 {)}^{2} [/tex]
Hence, the answer is (10x + 9)².

Answer:
1.) 138
2.) 55
Step-by-step explanation:
1.) 8 x 6 = 48 x 2 = 96
(middle) 8 x 3 = 24
(triangles) 6 x 3 = 18 divided by 2 = 9 x 2 = 18
96 + 24 + 18 = 138
2.) (middle) 5 x 5 = 25
(triangles) 5 x 3 = 15 divided by 2 = 7.5 x 4 = 30
30 + 25 = 55

This is ur answer.....
Measure angle 2 = 125M.A 1 = 180 - 125 ( Supplementary angle)
M.A 1 = 55
M.A 3 = 125 (Vertically Opposite Angles)
M.A 4 = 55 (Vertically Opposite Angles)
M.A 5 = 55 ( Corresponding Angle)
M.A 6 = 125 ( Corresponding Angle)
M.A 7 = 125 ( Vertically Opposite Angle)
M.A 8 = 55 ( Vertically Opposite Angle)

Answer:
∠1 = 55°
∠3 = 125°
∠4 = 55°
∠5 = 55°
∠6 = 125°
∠7 = 125°
∠8 = 55°
Step-by-step explanation:
This is the detective case for vertical angles!!(dun-dun-dun!!!!)
Ok the info we have is that Angle 2 is 125°
Ok, quick, take ten seconds, the other group might take the victory coin. What is the vertical angle for angle 2?
-----
3! Correct
3 is the vertical angle because it is one part of the pair of opposite angles made by two intersecting lines.
3 is now 125°
The sum of all angles 1,2,3,4 is 360°
360° - 125° - 125° = 110°
110° / 2 (because 1 and 4 are vertical, they are equal) = 55°
1 = 55° and 4 = 55°
Lets do this for 5,6,7, and 8
Angle 1 = angle 5 because it is the law of same side interior(corresponding) angles, or they are the same because the lines are parallel to each other.
So angle 5= 55°
then angle 8 = 55°
6 = 125° and 7 = 125°
Yay you beat the other team. Great job you win a victory coin(which basically is something that is absolutely nothing)

find the length of side a
Answer:
a = 4
Step-by-step explanation:
a² = 5² - 3²
a² = 25 - 9 = 16
√16 = 4
a = 4
Answer:
a = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 3² = 5²
a² + 9 = 25 ( subtract 9 from both sides )
a² = 16 ( take the square root of both sides )
a = [tex]\sqrt{16}[/tex] = 4

f(x) = –x^2 – 4x
Find f(-1)
Answer:
3
Step-by-step explanation:
Evaluate F(x) = –x^2 – 4x by substituting -1 for x:
F(-1) = –(-1)^2 – 4(-1)
This becomes:
F(x) = –1 + 4 = 3
Eight burgers and three orders of fries cost $79.49. Six orders of fries and twelve burgers cost $125.82.Find the price of one burger and one order of fries .
Answer:
Burgers - $8.29 and fries - $4.39Step-by-step explanation:
Let burgers - b, fries - f
8b + 3f = 79.4912b + 6f = 125.82Double the first equation and subtract the second equation:
16b + 6f - 12b - 6f = 2(79.49) - 125.824b = 33.16b = 33.16/4b = 8.29Find f:
8(8.29) + 3f = 79.493f = 79.49 - 66.323f = 13.17f = 13.17/3f = 4.39Xian plans to run 14 laps around a track, each lap is 400 yards which would make his run a total of 5600 yards. So far Xian has run 1,680 yards around the track. What percentage of the run has Xian completed?
