Answer:
28
Step-by-step explanation:
DI is a radius, which is half of a diameter. CJ is a diameter, so you just double toe radius which is 14, to get 28.
Answer:
28
Step-by-step explanation:
Since DI is 14, then DJ would be the same length, and so would DC. So we add DJ plus DC, which is 14+14. 28 is our answer.

Answer:
144 cm²
Step-by-step explanation:
for the triangle sides: 3 x 4 = 12 ((3 x 4/2)x 2)
for the front: 5 x 11 = 55
for the back: 3 x 11 = 33
for the base: 4 x 11 = 44
12 + 55 + 33 + 44 = 144
Answer:
144 units²
Step-by-step explanation:
We can see this shape is made of 2 shapes that we are familiar with 3 rectangle's and 2 triangles. In order to work out the surface of the prism we need to know how to work out the area of a rectangle and a triangle.
→ Area of triangle = 0.5 × Base × Height
→ Area of rectangle = Length × Width
First let's work out the area of the triangle and then double it to find the added area of the 2 triangle's
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
Area of triangle = 0.5 × 4 × 3
→ Simplify
Area of triangle = 6
Then double this value to find the combined value of the 2 triangle's
6 × 2 = 12
Now the area of the large rectangle
Area of rectangle = Length × Width
→ Substitute in the values
Area of rectangle = 11 × 5
→ Simplify
Area of rectangle = 55
Now the area of the medium rectangle
Area of rectangle = Length × Width
→ Substitute in the values
Area of rectangle = 11 × 4
→ Simplify
Area of rectangle = 44
Now the area of the small rectangle
Area of rectangle = Length × Width
→ Substitute in the values
Area of rectangle = 11 × 3
→ Simplify
Area of rectangle = 33
Now we add all the area's together,
33 + 44 + 55 + 12 = 144
NEEEDDD HHEELLPP NNOOWW. URGENTT giving 100 points and brainliest The mass of an empty jar is 470 g. 6 marbles are placed in the jar. The total mass of the jar and marbles is now 1.1 kg. Two of the marbles are removed. What is the mass of the jar and marbles now?
Answer:
890
Step-by-step explanation:
Well, first we should put 1.1 kg into grams (1 kg = 1000g)
1.1kg= 1100g
[tex]1100-470= 630[/tex] this is how much was added by the marbles
630/ # of marbles gives the mass of each marble
[tex]\frac{630}{6} = 105[/tex]
each marble has a mass of 105 g
1100- 2m(marble)=
1100-2*105
1100-210=
890
Answer:
890 grams
Step-by-step explanation:
Remember that one kilogram is equal to 1000 grams. Therefore, 1.1 kilograms is equal to 1,100 grams. (remember 0.1 means one tenth, and one tenth of 1000 is 100)
1,100 grams is the total measure of the jar with the marbles. Subtract the weight of the jar, 470 grams, to find the measure of the marbles.
1100 - 470 = 630
Now, we can divide 630 grams by the total number of marbles, 6, to find the weight of each marble.
630/6 = 105.
Therefore, each marble weighs 105 grams.
Now, we know that two marbles were removed from the jar that weighs 1100 grams.
Multiply 105 by 2 to find the number of grams that were taken out of the jar:
105*2 = 210
Now, we subtract 210 from 1100
1100 - 210 = 890 grams

A text message can have a maximum of 160 characters. If Daisy has typed 3 sentences with 45
characters each, then which equation can be solved to find the number of characters she can still
type. Let "c" equal number of Daisy characters left.
Answer:
c = 160 - 3(45)
Step-by-step explanation:
if c = the number of characters left;
160 = maximum number of characters that can be used in a text
3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)
(# of char left) = (max # char) - (# char already used) so:
c = 160 - 3*(45)
c = 160 - 135
c = 25

What is the surface area of the regular pyramid given below?
A. 144 units2
B. 352 units2
C. 176 units2
D. 208 units
Answer:
The surface area of the pyramid is 208 units²
Step-by-step explanation:
Luckily, since this is a square pyramid, we only need to find two numbers. These two numbers are the area of the base and the area of one triangular side. After we find them, we need to add them all together.
First, the base:
Since it's a square, we can just do 8 · 8 and get 64. Now we have one of the two needed numbers.
Second, one of the triangles:
To start, we multiply the base (8) by the height (9) giving us 72. After we divide that by 2, we have the area of the triangle, which is 36. Now we have the second number down. Now we can...
Finally, add them all together:
Now that we have the area of the base (64) and one of our triangles (36), we need to add them together. We add the base once and the triangle four times (because there are four triangles) to get the total surface area. Our expression looks like this:
64 + 36 + 36 + 36 + 36
After doing some simplifying, we get our final number, 208.
The surface area of the pyramid is 208 units²
The surface area of the regular pyramid in the diagram is 208 units².
What is the Area of a Pyramid?The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base.
Surface area of the pyramid = 2bh + b²
Where b is the base
and h is the perpendicular height of each triangular faces
In the given diagram,
b = 8
h = 9
∴ Surface area of the pyramid = 2×8×9 + 8²
Surface area of the pyramid = 144 + 64
Surface area of the pyramid = 208 units²
Hence, the surface area of the regular pyramid in the diagram is 208 units².

Mention a few number systems and explain in brief
Answer:
Step-by-step explanation:
The system is common use is the decimal system which is based on 10;
So for example the number 45 :
45 = 4 * 10^1 + 5 * 10^0 and
132 = 1*10^2 + 3*10^1 + 2*10^0.
The single digits in the decimal system are 0,1,2,3,4,5,6,7,8 and 9 .
Then we have 10, 11 and so on
Then there is the binary system which is based on 2 digits
In this system there are only 2 digits 0 and 1, so
10 binary = 1*2^1 + 0*2*0 which is equivalent to 2 in the decimal system.
111 binary = 1*2^2 + 1*2^1+ 1*2*0 = 4 + 2 + 1 = 7 decimal
Another system is the octal system, based on 8.
The digits are 0,1,2,3,4,5,6,7
So 10 octal = 8 + 0 = 8 decimal
and 17 octal = 1*8^1 + 7* 8^0 = 8 + 7 = 15 decimal.
