the sides may not seem to help but it dose go to the other side and try to meser it it would be 4. add 8+4+4 or 8+8=16

Answer:

18.6cm (rounded to 3 s.f.)  

Step-by-step explanation:

You can actually figure out the two bases of the triangles based on the Pythagoras theorem where the slant length of a 90° triangle is [tex]\sqrt{a^{2} + b^{2} }[/tex] where a is one of the bases and b is the other length that is 90° perpendicular to a.

So this means:

[tex]\sqrt{6^{2} + base^{2} }[/tex] = 8cm

6² + base² = 64cm

36 + base² = 64

base² = 64-36

          = 28

base = [tex]\sqrt{28}[/tex]

        ≈ 5.2915 (5 s.f.)

So the two bases are roughly 5.2915, and the middle base is part of a rectangle, so it has the same length as the rectangle's length, which is 8cm.

Thus, x = 5.2915 + 5.2915 + 8

            = 18.6cm (rounded to 3 s.f.)  

Answer:

The division model is 15 ÷ 3

Step-by-step explanation:

Required

Interpret the division model

A division model is of the form: Dividend ÷ Divisor

In the attached figure (in the question), there are 5 vertical partitions.

This vertical partitions represents the result of the model

Also from the question attachment;

The horizontal partitions on the left, if traced to the right side of the diagram means that each vertical partition is divided into 3 and this represents the divisor of the model.

So, we have:

[tex]Divisor = 3[/tex]

To get the quotient of the model, I'll make use of my attached file.

Counting the number of boxes, we can see that there are 15 boxes in total.

So, we have:

[tex]Dividend = 15[/tex]

Hence, the division model is: 15 ÷ 3

negatives are less than the positives so you start with the greatest negative and then go to the positives. The 0 is the origin.

Answer:

The trip is 50 miles long

Step-by-step explanation:

40 percent (or 20 miles) times 2 is 40 miles (80 percent).

Half of 40 percent is 20. And half of 20 is ten. 40 + 10 equals 50 miles! Hope this helps ^^

Answer:

500 grams.

Step-by-step explanation:

1kg = 1000grams.

0.5 * 1000 = 500grams.

Answer:

500 grams

Step-by-step explanation:

Because 1000grams = 1kg so 100 = 0.1

So to get this you multiply 0.5 with 1000

Answer:

about  3.21 hours each

Step-by-step explanation:

First divide 330 by 6 since there are six people.

Every person needs to do 55 decorations.

I would take the average of 2-4 minutes and multiply it by 55.

55 x 3.5 = 192.5 minutes

to convert to hours divide by 60.

192.5 / 60 = 3.21

Step-by-step explanation:

blue line = x

12c-8-2c+10-4=10c-x

(12-2)c+(10-4-8)=10c-x

10c-2=10c-x

Step-by-step explanation:

took the test

The area of the triangle is 15 square units if the triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2) option (b) is correct.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle ABC with altitude CD.

The coordinates for the triangle are A (-3, -4), B (-6, 2), C (0, 0), and

D (-4, -2)

From the figure, the distance between C and D will be the height of the triangle:

We can calculate the distance between the points by using the distance formula:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

h = √20

b = √45

Area of triangle = (1/2)bh = (1/2)√20×√45

= (1/2)30

= 15 square units

Thus, the area of the triangle is 15 square units if the triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2) option (b) is correct.

Onto the Problamo

We purchase 8 books in total. The first two books cost $7. So that 2/8 books purchased. now we need to purchase 6 more. Because It says: $3.50 per book, we do 3.50*6 or 3.50+3.50+3.50+3.50+3.50+3.50. so 7$ from the 2 books from the first statement plus $21 from the leftover 6 books.

7+21=28$

so I owe the school book fair $28 in the end
