Find the surface area
Answer:
pt for the triangles then 2(5x7) and 1(7x6) add it all together
Step-by-step explanation:
What is 25x²-4. What are the factors.
Answer:
(5x-2)(5x+2)
Step-by-step explanation:
Rewrite 25x2 25 x 2 as (5x)2 ( 5 x ) 2 .
Rewrite 4 as 22 .
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 - b 2 = ( a + b ) ( a - b ) where a=5x a = 5 x and b=2 .
What is the y-intercept of the graph of p(x)=-3(x-2)²+4
Answer:
The y intercept is -8, or (0, -8)
Step-by-step explanation:
p(x)=-3(x-2)²+4
p(x)=-3(x²-4x+4)+4
p(x)=-3x²+12x-12+4
p(x)=-3x²+12x-8
This is quadratic
In p(x)=ax²+bx+c
c is the y intercept
Therefore the y intercept is -8, or (0, -8)
Hope this helps! :D
<3
Answer:
(0,-8)
Step-by-step explanation:
The y intercept occurs when x = 0 , so put in x = 0
-3(0-2)^2 + 4 = -8
so y-axis intercept is ( 0, -8 )
Find Each missing measure in the following problem
Answer:
angle 2=62°
angle 3=66°
angle 1=147°
Step-by-step explanation:
ang 2=62° (vertically opposite angle )
62+90+142+angle 3=360° (sum of angle of quadrilateral is 360°)
294+ang 3=360°
angle 3= 360-294
angle 3=66
60+71+62+angle 1=360°
213+angle 1= 360°
angle 1= 147°
Fill in the blank spaces please.
PART A
If 4 pounds = 10 dollars...
4/2 = 2
10/2 = 5
So for 2 pounds, it would cost $5.00
Now for the 1 pound one
4/1 = 4
10/4 = 2.5
For the 1 pound one, it would cost $2.50
PART B
We know that 4 pounds = 10 bucks
Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb
Now for the last blank...
Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb

Mr.simpson is constructing a swing set for his children. He measures that the patform will be 7 feet high and would like to attach an 11-feet slide. How many feet away from the base will it be set? (Round to the nearest tenth.)
Answer:
8.5 ft
Step-by-step explanation:
We assume that Mr. Simpson can model his construction using a right triangle with leg 7 ft and hypotenuse 11 ft, as shown in the attachment. Then the other leg can be found using the Pythagorean theorem.
__
a² +b² = c²
x² +7² = 11²
x² = 121 -49 = 72
x = √72 = 6√2 ≈ 8.485 . . . . feet
The slide will be set about 8.5 feet away from the base.

In your own words describe how you would find the volume of a
figure using unit cubes?
Answer:
Volume = length x width x height.
You only need to know one side to figure out the volume of a cube.
The units of measure for volume are cubic units.
Volume is in three dimensions.
You can multiply the sides in any order.
Which side you call length, width, or height doesn't matter.

Answer:
4). 3
5). 600
Step-by-step explanation:
formula of finding intrest earned is (p×r×t)/100
by putting this formulae____
( HERE p means principal , r means rate , t means time )
(p×r×t) /100= interest
(480×r×5) / 100=100.80
(336×r) / 100 = 100.80
336×r= 100.80×100
r= (100.80×100)/336
r=3
5). (p×r×t)/100=interest
(p×4×5) /100 = 120.00
p×4×5 = 120.00×100
p= 12000 / 4×5
P=12000/20
P=600

A square has an area of 169 square feet. Select ALL the values that could represent the side length of the square in feet.
√169
169/4
169/2
13
√13
Answer:
√169 & 13
Step-by-step explanation:
the area of a square is = to one side squared
Because of this, the side should equal the square root of the area.
13 is the square root of 169, and the square root of the area, 169, are both options, and fulfill the area formula for squares
Cody made 3/4 of a kilogram of trail mix. If he puts 3/8 of a kilogram into each bag, how many bags can Cody fill?
A. 1/4 ÷ 3 = 1/12 and 4 × 3 = 12
B. 1/4 ÷ 3 = 1/12 and 1/4 × 1/3 = 1/12
C. 1/4 ÷ 3 = 1/12 and 3 ÷ 1/4 = 12
D. 3 ÷ 1/4 = 12 and 3 × 4 = 12
Answer:
2
Step-by-step explanation:
Considering x the number of bags he can fill:
x[tex]\frac{3}{8} x = \frac{3}{4} \\x = \frac{3}{4} X \frac{8}{3}\\ x =\frac{24}{12}\\ x = 2[/tex]

there is a distributive property error because they did not multiply both terms in the parenthesis by 2.
Factor the trinomial 6x²-5x-6, then find the sum of the factors.
Answer:
5x - 1
Find Factors:
6x²-5x-66x²-9x+4x-63x(2x-3)+2(2x-3)(2x-3)(3x+2)Factors: (2x-3)(3x+2)
Their sum:
(2x-3)+(3x+2)2x + 3x -3 + 25x - 1Factor the trinomial 6x²-5x-6, then find the sum of the factors .
Given : -An equation = 6x² - 5x - 6To Find : -Sum of their factors .Concept : -This question belongs to factorising the trinomial with the help of different methods such as middle term splitting .
Solution : -[tex] \longrightarrow \: 6x {}^{2} - 5x - 6[/tex]
Now , by splitting the middle term that is - 5 x :
[tex] \longrightarrow \: 6x {}^{2} - 9x + 4x - 6[/tex]
Now , taking 3x and -2 as common :
[tex] \longrightarrow \: 3x(2x - 3) + 2(2x - 3)[/tex]
So ,
[tex] \longrightarrow \: ( 3x + 2 ) ( 2x - 3 )[/tex]
Therefore , factors are ,
( 3x + 2 )( 2x - 3 )In the question we have ask to find the sum of their factors . So adding them ,
3x + 2 + 2x - 35x - 1Therefore , 5x - 1 is the sum of the factors .
#Keep LearningFind the measurements
Step-by-step explanation:
1) to calculate the measurement of Unlabeled angle:
180-90-27=63°;
2) to calculate the measurement of y:
180-51-63=66°
Answer:
y= 66
the angle that the arrow is pointing to = 63
Step-by-step explanation:
you can subtract 90 by 27 to get the angle measure that the arrow is 63
we know that all of the angles in a triangle are 180
so we can add up 51 and 63 to get 114
we subtract 180 by 114 to get 66
66 degrees

plss helpppppppppppppp
math problem answer sceenshot please
Answer:
Tbh I am not sure but it's a semi-circle prism or like semi cylinder (I think) but usually semi-circles themselves will not tessellate bc circles have no angles and when u line them up next to each other there will be gaps between them and one of the tessellation rules is that no overlapping or gaps so yeah
I am sorry lol if that's all wrong but my answer is no, I don't think that this figure is a tessellate plane

3yd is the diameter of this circle so
3yd × pi= 9.42yd
negative decimals on the number line 5
Answer:
B
Step-by-step explanation:
Since there is 10 lines separating -3 and -4, that means the space between 2 lines in 1 tenth, and b is 3.5 lines away from -3. Making it -3.35
have a nice day :)
Answer:
B
Step-by-step explanation:
Each section represents 0.1
You would count 3 sections to the left of -3 because -3.35 is less than -3. You would end up at -3.3. Move to the left half a section for 0.05 and you would end up at point B, which is equal to -3.35.
I hope this helps and please mark me as brainliest!
Is this line of best fit?
Answer:
No, it is not.
Step-by-step explanation:
The line of best fit is a line that runs across a scatter plot of data points and best reflects the connection between them. It must pass through the points on the graph for it to be the line of best fit.
Point H has coordinates (–7, 2). What are its coordinates after it is rotated 180° about the origin?

Step-by-step explanation:
question below......
Answer:
12π, option C is correct.
Using a shorter form of pi, the first step is to assign the default value for every circumference-radius problem. The r is the same value as radius, so in this case, that would be 6 m.[tex]C = 2\pi r[/tex]
Next, split this value into an equation, breaking down all 3 parts.[tex]2\pi r = 2 * \pi * 6[/tex]
Using the short form of pi, if you multiply all 3 numbers, your answer rounds to 37.68 m(Which is not on-the-nose, just an estimate that is extremely close to the real number).________________________________________________________
With the previous information, your answer is C.

what is the mean absolute deviation (MAD) of the data set? 79, 80, 82,84,87
Answer: 2.64
79 + 80 + 82 + 84 + 87 = 412
412/5 = 82.4
|79 - 82.4| = 3.4
|80 - 82.4| = 2.4
|82 - 82.4| = 0.4
|84 - 82.4| = 2.4
|87 - 82.4| = 4.6
3.4 + 2.4 + 0.4 + 2.4 + 4.6 = 13.2
13.2/5 = 2.64

Answer:
125˚
Step-by-step explanation:
The angles given are supplementary. So we can set up the equation :
(3x+5)+(x+15)=180
Then we can solve for x.
Combine like terms:
4x+20=180
4x+20-20=180-20
4x=160
4x/4=160/4
x=40
Now we plug in 40 for x.
3(40)+5=<A
120+5=<A
<A=125
