Answer:
x = 15 x = -13
Step-by-step explanation:
|x-1|=14
There are two solutions to the absolute value equation, one positive and one negative
x-1 = 14 and x-1 = -14
Add 1 to each side
x-1+1 = 14+1 x-1+1 = -14+1
x = 15 x = -13
Answer:
x= 13 or -13
Step-by-step explanation:
Substitute x for 13
|13+-1|=14
13+1=14
14=14
Now try -13
|-13+-1|=14
13+1=14
14=14

Answer:
216 2/3
Step-by-step explanation:
yoys : frents
6 : 13
We have 100 yoys
100/6 =50/3
Multiply by 50/3
yoys : frents
6 *50/3 : 13*50/3
100 : 650/3
As a mixed number
650/3 frents

How many water do you need to mix with 200ml of shampoo? How many water should you mix with 500ml of shampoo? If the correct amount of water is mixed with 400ml of shampoo will the mixture fit in a 2500ml container?
Answer:
200 mL shampoo - 1050 ml water
500 mL shampoo - 2625 mL water
Step-by-step explanation:
1) 400 ml shampoo , should be mixed 2500 - 400 = 2100 mL of water.
2) 400 mL shampoo - 2100 mL water
200 mL shampoo - x mL water
x = 200*2100/400 = 1050 mL water
3) 400 mL shampoo - 2100 mL water
500 mL shampoo - x mL water
x = 500*2100/400 = 2625 mL water
A smart-phone is thrown upwards from the top of a 240-foot building with an initial velocity of 32
feet per second. The height h of the smart-phone after t seconds is given by the quadratic equation
h = - 16t2 + 32t + 240. When will the smart-phone hit the ground?
Answer:
t = 5 sec
Step-by-step explanation:
h = - 16t² + 32t + 240
On the ground h = 0.
- 16t² + 32t + 240 = 0 / : (- 16)
t² - 2t - 15 = 0
(t-5)(t+3) = 0
t = 5, t = - 3
Time can be only positive, so t = 5 sec

Can you help me out on this question?
Answer:
4. x= 18
Step-by-step explanation:
We solve the problem like this:
Since 3 is proportional to 6 and 9 is proportional to x, we set up a proportion.
3/9 = 6/x
We then use cross-multiplication to solve for x.
The surface area of a cube is 24 square inches.
What is the side length of the cube?
Answer:
2 inches
Step-by-step explanation:
A cube has 6 faces. Therefore, each face is 4 square inches. (24/6) The side length of the square (face of the cube) is the square root of the area. The square root of 4 is 2. There is your answer :)

A briefcase in the shape of a rectangular prism has a height of 10 cm and a volume of 4,875 Centimeters cubed. What is the area of the base of the briefcase?
243.75 centimeters squared
487.5 centimeters squared
2,437.5 centimeters squared
4,865 centimeters squared
Answer:
Step-by-step explanation:
the correct question is
A briefcase in the shape of a rectangular prism has a height of 10 cm and a volume of 4,875 cm³. What is the area of the base of the briefcase?
we know that
volume of a rectangular prism=area of the base*height
volume=4875 cm³
h=10 cm
area of the base=volume/height
area of the base=4875/10-----> 487.5 cm²
the answer is
the area of the base is 487.5 cm³
Answer:
487.5 cm³

Find the value of x. If necessary, round to the nearest tenth
Answer:
8
Step-by-step explanation:
→ Use trigonometry to find x, we have no hypotenuse so we utilise the TOA formula
TOA = Tan = Opposite ÷ Adjacent
→ The opposite of the triangle is 8√3 and we want to find the adjacent of this triangle so we rearrange
Opposite ÷ Tan
→ Substitute in the values
8√3 ÷ tan(60) = 8

Step-by-step explanation:
Answer: A
Step-by-step explanation:
list the first 3 terms, then evaluate
Answer:
[tex]\sum\limits_{i=1}^{10}(1-2i)=-100[/tex].
Step-by-step explanation:
The given expression is
[tex]\sum\limits_{i=1}^{10}(1-2i)[/tex]
We need to find first 3 terms, then we have evaluate the value.
Here,
[tex]a_i=1-2i[/tex]
For i=1,
[tex]a_1=1-2(1)=1-2=-1[/tex]
For i=2,
[tex]a_2=1-2(2)=1-4=-3[/tex]
For i=3,
[tex]a_3=1-2(3)=1-6=-5[/tex]
So first three terms are -1,-3,-5. It is an AP with first term -1 and common difference -2. So, next 7 terms are -7,-9,-11,-13,-15,-17,-19.
Now,
[tex]\sum\limits_{i=1}^{10}(1-2i)=(-1)+(-3)+(-5)+(-7)+(-9)+(-11)+(-13)+(-15)+(-17)+(-19)[/tex]
[tex]\sum\limits_{i=1}^{10}(1-2i)=-100[/tex]
Therefore, the value of [tex]\sum\limits_{i=1}^{10}(1-2i)[/tex] is -100.

8x + 9y = 9 3x – 5y = 20 a. (3.36, –1.99) c. (0, –1.99) b. (–1.11, 2.79) d. (3.36, 2.79)
Answer:
x = 225/67 , y = -133/67 or decimal x≈3.3582 and y≈-1.9851, thus a. is the answer rounded.
Step-by-step explanation:
Solve the following system:
{8 x + 9 y = 9 | (equation 1)
3 x - 5 y = 20 | (equation 2)
Subtract 3/8 × (equation 1) from equation 2:
{8 x + 9 y = 9 | (equation 1)
0 x - (67 y)/8 = 133/8 | (equation 2)
Multiply equation 2 by 8:
{8 x + 9 y = 9 | (equation 1)
0 x - 67 y = 133 | (equation 2)
Divide equation 2 by -67:
{8 x + 9 y = 9 | (equation 1)
0 x+y = -133/67 | (equation 2)
Subtract 9 × (equation 2) from equation 1:
{8 x+0 y = 1800/67 | (equation 1)
0 x+y = -133/67 | (equation 2)
Divide equation 1 by 8:
{x+0 y = 225/67 | (equation 1)
0 x+y = -133/67 | (equation 2)
Collect results:
Answer: {x = 225/67 , y = -133/67

Answer:
B. 5.81
Step-by-step explanation:
So to get this answer, you'd first find how much square inches are on the cheese. We know its 9/10 of the pizza and the pizza is 215 square inches. To find out what is 9/10 of the pizza you'd multiply 215 by 9 then divide by 10. That'd leave you with 193.5 then you multiply that by the cost $0.03 then get 5.805 which rounds up to 5.81.
