Step-by-step explanation:
x+1 = 7
Subtract 1 from each side
x+1-1 =7-1
x =6
x^2 + 22 +1
6^2 +22+1
36+22+1
36+23
59
Answer:
[tex]x + 1 = 7 \\ x = 7 - 1 = 6 \\ putting \: the \: value \: of \: x = 6 \\ 6 \times 2 + 22 + 1 = 34[/tex]
A rope is 255 centimeters long you need the rope to be 1.5 meters long. How many centimeters should you cut off
Answer:
105cm
Step-by-step explanation:
first convert 1.5 metres to cm;
1m = 100cm
1.5 =?
1.5×100= 150cm
we then subtract:
255-150=105cm

Today Nia completed her sixth hour of training which represents her sixth hour of training, which represents 7.5% of the total number of hours in the training. How many hours will Nia spend in training in all?
The times spent in training is an illustration of proportions
The times spent in training is 80 hours
The given parameters are:
Time spent = 6 hours
Time spent as a percentage = 7.5%
Let the total time spent in training be x.
The scenario is represented by the following equation
Time spent = Time spent as a percentage * Total Time
So, we have:
6 = 7.5% * x
Express percentage as decimal
6 = 0.075 * x
Divide both sides by 0.075
80 = x
Rewrite as:
x = 80
Hence, the times spent in training is 80 hours

HELPP YALL! ILL MARK BRAINIEST!!! LOOK AT PICTURE!!!
Answer:
x=11
y=118
Step-by-step explanation:
pls can i have brainliest if im right
Answer:
x = 34°
y = 118°
Step-by-step explanation:
As ∠y and 62° are on the same line but lines P and Q are parallel to each other, they both add up to 180:
y + 62 = 180
y = 180 - 62
y = 118°
As this angle and 4x - 18 are corresponding angles, they both equal the same so:
4x - 18 = 118
4x - 18 + 18 = 118 + 18
4x = 136
[tex]\frac{4x}{4} = \frac{136}{4}[/tex]
x = 34°

An art gallery is increasing the asking price of its paintings by 60%. A painting now costs $400.00. How much was the painting before the increase??
$
Answer:
$250
Step-by-step explanation:
The goal here is to find the cost of the painting BEFORE the 60% increase.
To find the cost of the painting, we must take in the information we already have:
Increase percent: 60%
Original price: unknown
Price after increase: $400
$400 is the price of the painting AFTER the increase has been added. So this equals the cost of the painting before the increase, plus the total amount of the increase (which is 60% of the original price).
The total must be (100% + 60% = 160%) 160% of the original painting price.
To find the original price, we must divide the increased price by the new percentage (160%). But how do we get here?
Well, we have 160% and our (fraction) $400/1%. We will have to switch the 160% and the 1%, giving us..
1% $400/160%
We take 400/160, which is 2.5. But this is only 1% of the original price! We want 100%.
So now, we multiply the 2.5 by 100 to get our answer: $250.

Find the area of the shaded
figure.
Answer:
58 sq. units
Step-by-step explanation:
1. split them into 3 shapes
of course it is possible to count them all out, but the more efficient way would be to find the area of each shape and the add them all up.
2. find the area of rectangle a
so you can split one into a recantagle that separates itself from the 2 squares at the bottom
area formula: L x W
so the length of that rectangle is going to be 5, once you count the scares of that side. the width would be 10 when you count the top side of how wide it is.
5 × 10 = 50
3. find the area of the 2 squares
you don't need to find both, because one you find one, you find the other. so the length for the square would be 2 while the width is 2 as well.
2 × 2 = 4
so the area is 4, for each square.
50 + 4 + 4 = 58

pasagot please
answer it please
Answer:
Step-by-step explanation:
Let's start by looking at the graph of the two equations.
Since you are not looking for where the lines cross, I have chosen any 3 points for each equation almost randomly. I have not used either the x or y intercepts except once.
As a sample for the method of calculation
Let x -2y = 4
Let x = -2. Find y and put it in the table
-2 - 2y = 4 Add 2 to both sides
-2+2-2y = 4 + 2 Combine
-2y = 6 Divide by -2
y = 6/-2
y = - 3
Put that in the table under the first equation.
The other 5 points are done the same way.

12 ≥ p + 7 > 5
Answer:
-2 < p ≤ 5
Step-by-step explanation:
You can separate this into two inequalities and solve for each.
p + 7 ≤ 12
Solving for p, you get p ≤ 5
p + 7 > 5
Solving for p, you get p > -2
Combining the two equalities back together, you get -2 < p ≤ 5

Answer:
Below in bold.
Step-by-step explanation:
If the 3 points are on the circle with the given center then the distance from each point to the center will all be equal. This distance will be the radius of the circle.
Distance of P (2, 5) from the center (4, 2)
= √( (5-2)^2 + (2-4)^2)
= √(9 + 4)
= √13.
For Q (6, -1)this distance is:
= √(6-4)^2 + (-1-2)^2)
= √13.
For R (7, 4) his distance is:
= √(7-4)^2 + (4-2)^2)
= √13
These distances are the same so the points P, Q and R lie on the circle.
The midpoint of PQ
= (2+6)/2 , (5 - 1)/2
= (4, 2).
Which is the center so this verifies the second part.
Answer:
steps below
Step-by-step explanation:
P(2,5) Q(6,-1) R(7,4)
PQ² = (6-2)² + (-1 - 5)² = 16+36 = 52
QR² = (7-6)² + (4 - -1)² = 26
RP² = (7-2)² + (4-5)² = 26
PQ² = QR² + RP²
∴PQR is a right angle triangle and PQ is hypotenuse and it's the diameter of circumscriber triangle
∴P,Q,R are on a circle centered at the mid-point of PQ (4,2) - bisector of PQ
** property of right triangle: For any right triangle, the hypotenuse is a diameter of the circumscribed circle, i.e. the center of the circle is the midpoint of the hypotenuse

You are taking a true/false quiz with 9 questions. What is the probability of getting all 9 questions correct?
Answer:
If you guess do this -
.5(9)
Basically about a 4.5% chance of getting all right.
Answer:
Step-by-step explanation:
each question has 2 answer choices, so 1 or the 2 is correct, and to get all 9 in a row correct would be like this
1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2
because theres a 1 in 2 chance of getting each question right, and there are 9 questions
1/2^9 = 0.00195 = 0.195%
