Triangles have a total of 180°. Use the triangle below to determine the value of X.
Answer:
3x=105
x=35
Step-by-step explanation:
40+3x+x = 180 (Angle sum property)
40 +4x=180
4x = 180-40
140
x = 140/4
=35
3x = 35 x 3
105
x = 35

a grid of a hundred square show 7 shaded squares what decimal number is represented
Answer:
0.07
Step-by-step explanation:
From the question, a given grid was divided into a definite number of squares with some of the squares shaded.
Total number of squares in the grid = 100
number of shaded squares in the grid = 7
Thus, 7 squares are shaded out of 100 square in the grid.
So that this can be expressed in fraction as;
[tex]\frac{number of shaded squares}{total number of squares}[/tex] = [tex]\frac{7}{100}[/tex]
= 0.07
The decimal number of the squares represented is 0.07.

The part of a cylindrical soup can that is covered by the label is 8.5 cm tall and has a diameter of 6.5 cm. What is the area of a label that covers the entire side of the can and that need a 0.8-cm overlap to glue the ends of the label? Round to the nearest tenth.
Answer:
[tex]180.4~cm^2[/tex]
Step-by-step explanation:
Surface Area
The surface area of a cylinder of height h and radius r is given by:
[tex]A=2\pi rh[/tex]
It only covers the lateral side of the cylinder. If both the top and the bottom sides are to be included, then:
[tex]A=2\pi rh+2\pi r^2[/tex]
The label will cover only the lateral side of the soup can that has a height of h=8.5 cm and a diameter of 6.5 cm. We need to calculate the radius which is half of the diameter r=6.5 cm / 2 = 3.25 cm.
Now we calculate the side area of the can:
[tex]A=2\pi (3.25)(8.5)[/tex]
[tex]A=173.6~cm^2[/tex]
We need to add the 0.8 cm overlap to the total area already calculated. This overlap has 0.8 cm of width and 8.5 cm of height, so this overlap area is:
[tex]A_o= 0.8*8.5=6.8~cm^2[/tex]
The total area of the label is:
[tex]A=173.6~cm^2+6.8~cm^2=180.4~cm^2[/tex]
The area of the label is [tex]\mathbf{180.4~cm^2}[/tex]

Anjelica is using synthetic division to divide 2x3−9x2−21x+10 by x+2 .
Which answer is correct?
Answer:
B I the answer I just did the same question
Anjelica is using synthetic division to divide
[tex]\:\frac{\left(2x^3-9x^2-21x+10\right)}{x+2}[/tex]
Steps given in option B are correct
Given :
Divide the given expression
[tex]\:\frac{\left(2x^3-9x^2-21x+10\right)}{x+2}[/tex]
Apply synthetic division
In synthetic division , we write all the coefficient inside the division
then solve the denominator for x and write it outside
[tex]x+2=0\\x=-2[/tex]
so we write -2 outside the division sign
Take down first number 2 as it is . Then multiply with -2 and put it below the second number . Add it and write it down . Continue the process.

5. €1575 was shared among three people in the ratio 1:2:1/2
Calculate the smallest share.
Answer:
€225
Step-by-step explanation:
Given that:
1575 shared in the ratio 1 : 2 : 1/2
Total sum of ratio = (1 + 2 + 1/2) = 3 1/2
Ratio 1 amount :
(1 / 3.5) * 1575 = 450
Ratio 2 amount :
(2 / 3.5) * 1575 = 900
Ratio 1/2 amount :
(1/2 ÷ 3.5) * 1575 = 225
Smallest share = $225
A circle has a radius of 13cm . Find the radian measure of the central angle 0 that intercepts an arc of length8cm . Do not round any intermediate computations, and round your answer to the nearest tenth.
Answer:
The measure of the center angle is 0.6 radians
Step-by-step explanation:
Mathematically, the length of an arc can be calculated using;
L = theta/360 * 2 * pi * r
where theta is the central angle
In this case, theta = ? , pi = 22/7 and r is 13
cm, length of arc is 8 cm
So we have ;
8 = theta/360 * 2 * pi * 13
360 * 7 * 8 = theta * 2 * 22 * 13
20,160 = 572 theta
theta = 20,160/572
theta = 35.24
let us convert this to radian measure
Mathematically, 1 degree = 0.0175 radian
Thus 35.24 degrees will be 35.24 * 0.0175 = 0.62 radians
To the nearest tenth, this is 0.6 radians
Why do plants provide animals with fruits such as strawberries, apples, and mangoes?
Answer:
For seed transfer. If an animal gathers fruit and eats it or just carries it away for later consumption, it will move the seed further away from the parent plant. That way, the new plants do not take from the parent plant's resources.

At the time this question was written, one US Dollar equaled 0.88 Euros. What would 50 Euros equal in US Dollars? Round your answer to the nearest cent.
Answer:
$56.82 US dollars
Step-by-step explanation:
Set up a proportion where x is how many US dollars there are in 50 Euros:
[tex]\frac{1}{0.88}[/tex] = [tex]\frac{x}{50}[/tex]
Cross multiply and solve for x:
0.88x = 50
x = 56.82
So, 50 Euros is approximately equal to $56.82 US dollars
