Answer:
320
Step-by-step explanation:
multiples of -4
Answer:
320
Step-by-step explanation:
it looks as if it is multiplied by -4 every time.
-5 x -4 = 20

A person has a rectangular board 12 inches by 16 inches around what she wants to put a uniform border of shells if she hasn't of shells were border whose area is 128 square in determine the width of the Border
Answer:
2 inches
Step-by-step explanation:
Given that:
Dimensions of rectangular board = 12 inches by 16 inches
Area of uniform border around the rectangular board = 128 square inches
To find:
Width of the border = ?
Solution:
Let the width of the uniform border = [tex]x[/tex] inches
Now, there are two rectangular shapes after the addition of border.
One rectangle with the border, one without the board.
Area of border can be found by subtracting the area of board from the area of rectangle with the board.
Dimensions of the rectangle with the border = (12+2[tex]x[/tex]) inches by (16+2[tex]x[/tex]) inches
Area of rectangle = Length [tex]\times[/tex] Width
So, area of border = ((12+2[tex]x[/tex]) [tex]\times[/tex] (16+2[tex]x[/tex])) - 16 [tex]\times[/tex] 12 = 128 square inches
[tex]\Rightarrow 4x^2+56x+192-192=128\\\Rightarrow 4x^2+56x-128=0\\\Rightarrow x^2+14x-32=0\\\Rightarrow (x+16)(x-2)=0\\\Rightarrow x = 2, -16[/tex]
Width can not be negative, so possible value of width = 2 inches

I believe the awnser is negative
What is the slope of the line that passes through the points (4, -1)
And (-2,4)
Answer:
-5/6
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
4-(-1)/-2-4
5/-6
-5/6
Best of Luck!
Answer:
5/-6
Step-by-step explanation:
The slope formula is (y2 - y1)/(x2-x1).
Plug in the numbers.

If the measure of angle 1 is (3 x minus 4) degrees and the measure of angle 2 is (4 x + 10) degrees, what is the measure of angle 2 in degrees?
A horizontal line. A line extends from the line to form a 90 degree angle. Another line cuts through the 2 lines to form angles 1 and 2, which total 90 degrees.
32 degrees
38 degrees
58 degrees
66 degrees
Answer:
58 degrees
Step-by-step explanation:
3x-4+4x+10=90
7x+6=90
7x=84
x=12
4(12)+10=angle 2
58 degrees = angle 2
Answer:
C. 58 Degrees

Your brother has a bag of marbles. He has 8 green marbles, 3 blue marbles, 7 red marbles, and 2
yellow marbles.
What is the ratio of blue and yellow marbles to red marbles?
(Write your ratio as a
fraction)
Answer:
3+2:7
Step-by-step explanation:
Answer:
1/5
Step-by-step explanation:
Blue mables: 3
green and red marbles: 8 + 7 = 15
then, the radio blue:(green+red) is:
3 : 15
simplified unit rate is:
3/3 = 1
15/3 = 5
then:
3:15
is equal to:
1:5
=
1/5
t÷5/12= -3/10
Thank you if you help :)
Answer:
t = -1/8.
Step-by-step explanation:
t / 5/12 = -3/10 Invert the 5/12 and multiply:
12t / 5 = -3/10
Cross multiply:
12t * 10 = 5 * -3
120t = -15
t = -15/120 = -1/8.

Twenty people each had 36 carrots. How many carrots are there altogether?
You know that there are 25 people and each person had 36 carrots. To find how many carrots everyone has in total, you have to multiply 25 by 36.
25 times 36 is 900.
There are 900 carrots altogether.
In Triangle JKL, ∠J is congruent to ∠L. Triangle J K L is shown. Ray L K extends beyond point K to form an exterior angle that is labeled sixty-seven and eight tenths degrees. What is the measure of ∠L? Enter the correct answer in the box.
Answer:
m<L = [tex]33.9^{o}[/tex]
Step-by-step explanation:
Triangle JKL is an isosceles triangle, given that <J ≅ <L. An isosceles triangle has two of its angles and sides to be equal.
The exterior angle formed = [tex]67.8^{0}[/tex]
But,
<J + <L = [tex]67.8^{0}[/tex] (the sum of two opposite interior angles is equal to the exterior angle)
Let <J ≅ <L be represented by a, so that;
a + a = [tex]67.8^{0}[/tex]
2a = [tex]67.8^{0}[/tex]
a = [tex]\frac{67.8^{o} }{2}[/tex]
= [tex]33.9^{o}[/tex]
The measure of <L is m<L = [tex]33.9^{o}[/tex] (m<L =
Thus,
m<J ≅ m<L = [tex]33.9^{o}[/tex]

A bottle of water contains 450ml. How many litres of water are there in 8 of these bottles
Answer:
3.6 litres
Step-by-step explanation:
1 bottle = 450ml
8 bottles = 450 × 8
= 3600ml
1000ml = 1 litre
3600ml = 3.6 litres (3600÷1000)
Answer:
3.6 litres
Step-by-step explanation:
1 bottle = 450ml
8 bottles = 450 × 8
= 3600ml
1000ml = 1 litre
3600ml = 3.6 litres (3600÷1000)
