Answer:
33
Step-by-step explanation:
Alright, so, let's break it down.
We know that d = negative 6 (-6)
Lets start with -5d.
Since d = -6, we have to do -5 × -6, which is 30.
So, now, we are using fractions. -6 plus 15.
(Which is, negative 6 plus 15)
That is 9. Since we are adding a negative number to a positive number, it will be the same way as 15 minus 6.
Now, we know that we are using division (due to the fraction line, we know that we are using division). Let's divide 9 into 3. That's 3, because 3 times 3 is also 9. Now, if we add 30 plus 3, we get 33, Therefore, the answer is 33.
Answer:
33
Step-by-step explanation:
-5(-6) + (-6) + 15/3
30 + -6 + 15/3
30 + 9/3
30 + 3

The Bridge Problem
A group of four people has to cross a bridge. It is dark, and they have to light the path with a flashlight. No more than two people can cross the bridge simultaneously, and the group has only one flashlight. It takes different time for the people in the group to cross the bridge:
Chris crosses the bridge in 1 minute,
Tracy crosses the bridge in 2 minutes,
Ashley crosses the bridge in 5 minutes,
Jalen crosses the bridge in 10 minutes.
How can the group cross the bridge in 17 minutes?
So, the first thing is that the group requires flashlight to cross the bridge. It also means that each time one person must return to bring back the flashlight.
Chris and Tracy cross the bridge in 2 minutes. ( The maximum time required by both of them would be 2 minutes)
Then Chris would return with flashlight in 1 minute.
Ashley and Jalen then cross the bridge in 10 minutes.
Now, Tracy will return with flash light in 2 minutes.
Then, Chris and Tracy will cross the bridge in 2 minutes.
Total time taken => 2+1+10+2+2 => 17 minutes.
Hope this helps :)
Answer:
Chris and Tracy cross the bridge together = 2 minutes
Chris goes back on his own (leaving Tracy across the bridge) = 1 minute
Chris gives the flashlight to Ashley
Ashley and Jalen cross the bridge together = 10 minutes
They give the flashlight to Tracy (who was waiting across the bridge)
Tracy goes back = 2 minutes
Chris and Tracy cross the bridge together = 2 minutes
Total 17 minutes

three boys share R2100 in ratio 3:5:7 calculate how much each boy will get
The amount each boy receives from the R2100 is R420, R700 and R980 respectively
How to find ratioTotal amount = R2100
Ratio = 3 : 5 : 7
Total ratio = 3 + 5 + 7
= 15
First boy = 3/15 × 2100
= 0.2 × 2100
= R420
Second boy = 5/15 × 2100
= 0.33333333333333 × 2100
= R700

In rhombus ABCD, segments AC and BD are diagonals. If mZDAB = 160°, what is the measure of ZABE?
OA. 190°
ОВ.
170°
OC
10°
D.
100
Answer:
The correct option is OPTION C.
Step-by-step explanation:
Recall that for a rhombus, the diagonals bisect the interior angles.
This means that if we are given that:
m∠DAB=160°
Then:
m∠EAB=m∠DAB/2=160/2=80°
Also, recall that the diagonals of a rhombus are perpendicular. Therefore:
m∠AEB=90°
Hence, we can have a triangle that looks like the one shown below:
Recall that the sum of angles in a triangle is 180°. Therefore, we have that:
m∠AEB+m∠ABE+m∠EAB=180°
Hence, we can calculate m∠ABE to be:
m∠ABE =180-80-90
m∠ABE=10°
The correct option is OPTION C.
What is an equation of the line that passes through the points (-4, -5) and
(-8, -2)?
To find the equation, First step is to find the slope which we can use in the formula and then we will find the equation using the specific formula...
Finding slope ⤵️[tex] \boxed{ \sf \:m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} }[/tex]
(x1,y1) = (-4,-5)(x2,y2) = (-8,-2)[tex] \tt \to \: m = \frac{ - 2-( - 5)}{ - 8 -(- 4)} [/tex]
[tex] \tt \to \: m = \frac{ -2+5}{ -8+4} [/tex]

Now, Put the values in the formula used to find the equation ⤵️[tex] \boxed{ \sf \:y - y_{1} = m(x - x_{1}) }[/tex]
(x1,y1) = (-4,-5)[tex] \tt \nrightarrow \: y - ( - 5) = - \frac{3}{4} (x - ( - 4))[/tex]
[tex] \tt \nrightarrow \: y + 5 = - \frac{3}{4} (x + 4)[/tex]

What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
Here, we have
two points (-4, -5) and (-8, -2)
So, by using the formula of equation of straight line of two-point form, we get,
(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )
=>(y+5)/(x+4)=(-2+5)/(-8+4)
=>(y+5)/(x+4)= 3/ -4
=>-4y - 20 = 3x +12
=> -4y = 3x + 32
=> y = -3x/4 -8
Hence, the required equation is, y = -3x/4 -8

Additional comment
A pattern will have horizontal reflection if there exists a vertical line about which the pattern can be reflected to itself. That is, there exists one (or more) vertical lines of symmetry.
Similarly, the pattern will have vertical reflection if there is a horizontal line about which the pattern can be reflected to itself. Such a line is a horizontal line of symmetry.

Graph the points (3,3) and (2,1) on the coordinate plane.
Answer:
1. Over three, up three
2. Over two, up one
Step-by-step explanation:
Given the following question:
Point A = (3, 3)
Point B = (2, 1)
To find the answer, please understand where the x and y axis is located. Remember that the x is the line intersecting the y axis.
So, in order to plot point A and B, we have to remember that the first value represents x, and the second represents the y value.
(3, 3) = (x, y)
(2, 1) = (x, y)
For the first point we will move over three on the x axis, and then up three on the y axis.
For the second point we will move over two on the x axis, and then up 1 on the y axis.

Please i need help, can someona explain how to solve the problems with the most easiest way to solve? Because this is so confusing
Answer:
Above your sheet, they give you formulas for the rectangular prism.
Method one;
V = L x W x H
Where "L" is length, "W" is width, and "H" is height.
Method 2;
V = B x H
Where "B" is the area of the base, and "H" is the height.
Now let's apply these formula to your questions:-
(Using method 2 for most of these problems)
1. If we look for the area of the base, we can see that 2 is the width and 4 is the length, so we would need to multiply those two to get the area of the base (2 x 4) = 8.
Now the height is 3.
So we plug this into our formula,
V = B x H
V = 8 x 3
V = 24 cubic feet
2. If we look at this question, we can see that this is a cube, meaning that all lengths are the same. To make this easier, we can use method 1 and just multiply the given lengths;
V = L x W x H
V = 4 x 4 x 4
V = 64 cubic inches
3. If we look for the area of the base, we can see that 5 is the width and the length is 20, so we would need to multiply those two to get the area of the base (5 x 20) = 100.
The height is 5.
So we plug this into our formula;
V = B x H
V = 100 x 5
V = 500 cubic yards
4) If we look for the area of the base, we can see that 3.2, if i'm correct, is the width and 5.4 is the length, so we would need to multiply those two to get the area of the base (3.2 x 5.4) = 17.28.
The height is 1.9.
So we plug this into our formula;
V = B x H
V = 17.28 x 1.9
V = 32.832, 32.83 cubic centimeters
