6th grade math help me please...
Answer:
B and D
Step-by-step explanation:
a. 5t+4t =9t
b. t+5+4= t+9
c. 9t
d. 4×5×t= 20t
e. t(5+4)- do the inside the parenthesis first. =9t
the answer would me B and A because the answer isn't 9t so it would be those!! also the boxes on the right you multiply t×5 and t×4 and that would be 5t + 4t =9t

Answer:
√53
Step-by-step explanation:

base (b) = 6
perpendicular (p) = ?
we know by using Pythagoras theorem
p = √(h² - b²)

The longest side of triangle is 10 cm which group of line segments could form the other 2 sides of the triangle
Answer
A 5cm and 5 cm
B 7cm and 8cm
C 4cm and 4cm
D 9cm and 10 cm
Please i need to know
Answer:
The group of line segments that could form the other 2 sides of the triangle is;
B. 7 cm and 8 cm
Step-by-step explanation:
The triangle inequality theorem states that the sum of the length of any two sides of a triangle is larger than the length of the third side
The given parameter of the triangle is that the length of the longest side of the triangle = 10 cm
Let, 'a', and 'b', represent the remaining two sides of the triangle
Therefore, by the triangle inequality theorem, we have;
(1) a + b > 10 cm
(2) 10 cm + a > b
(3) 10 cm + b > a
The option that satisfies condition (1), (2), and (3) are options 'B' and 'D', for which we have;
7 cm + 8 cm = 15 cm > 10 cm
10 cm + 7 cm = 17 cm > 8 cm
10 cm + 8 cm = 18 cm > 7 cm
9 cm + 10 cm = 19 cm > 10 cm
10 cm + 9 cm = 19 cm > 10 cm
10 cm + 10 cm = 20 cm > 9 cm
Therefore, the possible combination of the other two sides are;
7 cm and 8 cm or 9 cm and 10 cm
However, a side of option 'D' is 10 cm and given that the longest side of the triangle = 10 cm, the length of each of the other two side should be less than 10 cm and the only given possible combination of the other two side should be option 'B', 7 cm and 8 cm.
Answer:
B 7cm and 8cm

Consider this system of equations, which equation represents the first equation written in slope-intercept form? 5x - 2y = 10 O y=x-5 oy-x+10 o y--x+10 O y=-5x -5 ..... brainlyist for who is right
Answer:
The answer is A
Step-by-step explanation:
this isnt my answer it is someone named baylee in the comments, i tried it and it was right .
As per the given data, the slope-intercept form of the first equation is y = x - 5, which is represented by option A.
What is slope-intercept?The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept.
The equation that represents the first equation written in slope-intercept form is:
y = x - 5
To convert the equation 5x - 2y = 10 into slope-intercept form, we need to isolate y on one side of the equation.
Starting with 5x - 2y = 10:
Subtract 5x from both sides: -2y = -5x + 10
Divide both sides by -2: y = (5/2)x - 5
Now, we can simplify the expression (5/2)x - 5 to the form y = mx + b, where m is the slope and b is the y-intercept.
Therefore, the correct option is A.

find the volume of metal required to make a closed box of thickness 1 cm with external measurements 12 cm × 7 cm × 10
Answer:
The volume of the metal is:
[tex]V_{t}=548\: cm^{3}[/tex]
Step-by-step explanation:
First, let's find the volume of the front face of the square:
[tex]V_{1}=12*7*1=84\: cm^{3}[/tex]
The back face is the same, so we have:
[tex]V_{2}=84\: cm^{3}[/tex]
The volume of the side faces will be:
[tex]V_{3}=7*10*1=70\: cm^{3}[/tex]
[tex]V_{4}=70\: cm^{3}[/tex]
And finally, the volume of the top and bottom side faces of the box will be:
[tex]V_{5}=12*10*1=120\: cm^{3}[/tex]
[tex]V_{6}=120\: cm^{3}[/tex]
The total volume of the metal will be:
[tex]V_{t}=V_{1}+V_{2}+V_{3}+V_{4}+V_{5}+V_{6}[/tex]
[tex]V_{t}=2(84)+2(70)+2(120)[/tex]
[tex]V_{t}=548\: cm^{3}[/tex]

A wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. Find the speed of the boat as she paddles if the river current is 2 km/h (2 answers)
Answer:
Step-by-step explanation:
5 km/h or 6 km/h
Step-by-step explanation:
Let the speed of the boat be x
Speed against the current in the river is x - 2
Time in the river:
6/(x - 2)
Time in the lake:
15/x
The difference:
6/(x - 2) = 15/x - 1
Solve for x to find the speed of the boat
Multiply both sides by x(x - 2) to clear the fraction:
6x = 15(x - 2) - x(x - 2)
6x = 15x - 30 - x² + 2x
x² - 11x + 30 = 0
(x - 5)(x - 6) =0
x -5 = 0, x - 6 = 0
x = 5 km/h, x = 6 km/h
b. x +6 <-8 and x-1 > -1

since a triangle's total angle is 180 degrees,
(5x + 18) + (3x + 2) + (x + 16) = 180
9x + 36 = 180
9x = 144
x = 16
m<D = (3x + 2)
m<D = 3(16) + 2
m<D = 48 + 2
