Solve for x in the diagram below.
35°
5x°
Answer:
11
Step-by-step explanation:
5x° + 35° = 90°
(complementary angles)
5x° = 90° - 35°
5x° = 55°
x = 55/5
x = 11
Answer:
11
Step-by-step explanation:
35+5x = 90
5x = 90- 35
5x = 55
x = 55/5 = 11
I hope im right!!
y = x + 2
y = -5/2x-5
Does anyone know about Number Base? If so, please calculate this 11₂ + 10₂
Please answer it accurately or even close to it.
Answer:
101₂
Step-by-step explanation:
11₂ + 10₂
This is currently in base 2. The subscript tells you that. In the base 2 system, the only numbers allowed are; 0 and 1. This means if you were to have; 1 + 1, rather than getting 2, you have 10.

is -5(x+8) equal to -5x-40 pleaseeee i need helppp
Answer:
yes
Step-by-step explanation:
The distributive property of multiplication over additions is:
a(b + c) = ab + ac
You multiply the number outside the parentheses, the a, by each of the numbers inside the parentheses, the b and the c. Then you add the products.
Now we can do it with your example.
-5(x + 8)
We multiply -5 by x and multiply -5 by 8. Then we add the products and simplify.
-5(x + 8) = -5 * x + (-5) * 8 = -5x + (-40) = -5x - 40
Answer: yes
Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
13
5
6.5
Step-by-step explanation:
step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi
step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi
step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3
step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).
step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.

the cost of cereal is 35rand for 1 kg , calculate the cost of 25g
Answer:
7.14*10^-4rand
Step-by-step explanation:
If the cost of cereal is 35rand for 1 kg, this can be expressed as;
35 and = 1kg
To get the cost of 25grams, we can write
25g = x
0.025 kg = x
Divide both expressions
35/0.025 = 1/x
35x = 0.025
x = 0.025/35
x = 7.14*10^-4rand
Hence the cost of 25g is 7.14*10^-4rand

The question is in the picture below
9514 1404 393
Answer:
30 units
Step-by-step explanation:
Make use of the formula for the volume of a sphere. Solve for the radius. (You can solve for the radius before or after you put the numbers in the formula.)
V = (4/3)πr³
36000π = 4/3πr³ . . . . put the numbers in the formula
27000 = r³ . . . . . . . . . multiply both sides by 3/(4π)
30 = r . . . . . . . . . . . . . .take the cube root
The radius of the sphere is 30 units.
Answer:
radius = 30 units
Step-by-step explanation:
The radius of the sphere is 30 units.
Answer pls. question in photo
1/3 ( x - 10) = -4 ???
Answer:
[tex]x = - 2[/tex]
Step-by-step explanation:
1) Simplify 1/3 ( x - 10) to x-10/3.
[tex] \frac{x - 10}{3} = - 4[/tex]
2) Multiply both sides by 3.
[tex]x - 10 = - 4 \times 3[/tex]
Simplify 4 × 3 to 12.
[tex]x - 10 = - 12[/tex]
4) Add 10 to both sides.
[tex]x = - 12 + 10[/tex]
5) Simplify -12 + 10 to -2.
[tex]x = - 2[/tex]
So, therefor, the answer is, x = -2.

Maggie made 3kg of fudge. She and her friends ate some and now there are 1 3/4 kg left. How many kg of fudge did maggie and her friends eat?
Answer:
1 1/4 kg
Step-by-step explanation:
Maggie made 3kg of fudge. She and her friends ate some and now there are 1 3/4 kg left. How many kg of fudge did maggie and her friends eat?
The kg of fudge thay maggie and her friends ate is calculated as:
Initial kg of fudge - kg of fudge left
= 3 kg - 1 3/4 kg
3/1 kg - 7/4 kg
Lowest common denominator = 4
= 12 - 7/4 kg
= 5/4 kg
= 1 1/4 kg
