Houses cost £100 000 one year ago
They now cost £
This is a 25% increase
How much does it now cost ?
Answer:
£125000
Step-by-step explanation:
Original cost of house = £100 000
Percent increase = 25%
Increase in price = 25% of 100,000
Increase in price = 0.25 * 100,000
Increase in price = 25000
New cost = original cost + Increment
New cost = 100,000 + 25,000
New cost = 125,000
Hence it now cost £125000

The perimeter of a triangle is 19 units. The second side is four units longer than the first side and the third side is three times the length of the first side. What are the lengths of the sides?
Answer:
First: 3 units Second: 7 units Third: 9 units
Step-by-step explanation:
19=x+(x+4)+3x
19=5x+4
15=5x
x=3
first side is 3 units
3+4=7
second side is 7 units
3*3=9
third side is 9 units
solve : 3x - 3 = 2x
if you can show workings that would be great thank you !
Answer:
3
Step-by-step explanation:
3x-3=2x
3x-2x=3
x=3
Answer:
x=3
Step-by-step explanation:
3x - 3 = 2x
-3x -3x
-3 = -x
The x cannot be a negative so you divide both sides by -1 and then the answer becomes x=3

A billiard ball is struck by a cue. It travels 100 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the ball approaches the rail and the path after it strikes the rail is 45 degrees. How far is the corner pocket from where the cue initially struck the ball?
Answer:
76.53 cm
Step-by-step explanation:
From the question, the triangle formed has 2 sides and an included angle ;
Angle, θ = C = 45°
We use cosine rule :
Taking the side to find as c
a = 100 ; b = 100
From cosine rule :
c = sqrt(a² + b² - 2abCosC)
c = sqrt(100² + 100² - 2(100*100)Cos45
c = sqrt(10000 + 10000 - 20000 * 0.7071067)
c = sqrt(20000 - 14142.135)
c = sqrt(5857.865)
c = 76.536690
c = 76.53 cm
What is the area of this quadrilateral?
8 ft
6 ft
3.ft
A. 33 square feet
B. 42 square feet
C. 17 square feet
D. 66 square feet
Answer:
a. 33 sqft
Step-by-step explanation:
The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles
Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)
The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24
The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9
Total area is sum of these two or 24 + 9 = 33
Quadrilateral FGHI is similar to quadrilateral JKLM. Find the measure of side KL. Round your answer to the nearest tenth.
Answer:
The answer is "31.888".
Step-by-step explanation:
When their respective angles were congruent or their side lengths have a constant relation, they know that two quadrilaterals are similar
FGHI is similar to JKLM because of quadrilateral
[tex]\to \frac{FG}{JK} =\frac{GH}{KL}=\frac{HI}{LM}=\frac{FI}{JM}\\\\\to \frac{GH}{KL} =\frac{HI}{LM}\\\\\to \frac{7}{KL}= \frac{9}{41}\\\\\to KL=\frac{7 \times 41}{9}=31.888\\\\[/tex]

A)frozen yogurt
B)frozen custard
plz show the work i really need help and this is Compare rates: word problems
Answer:
A. Frozen yogurt
Step-by-step explanation:
The frozen yogurt costs less than the frozen custard, even though you get the same amount (3 ounces)
No matter how much money Marco has, he would be able to buy more of the frozen yogurt because it has a cheaper unit rate.
So, the answer is A, frozen yogurt

N/-3 - 2 = 8 n=___ help
Answer:
-30
Step-by-step explanation:
[tex]\frac{N}{-3} -2 =8[/tex] ( Add 2 on both sides)
[tex]\frac{N}{-3} = 10[/tex] ( Multiply by -3 on both sides)
[tex]N = -30[/tex]
Verify:
[tex]\frac{-30}{-3} =10[/tex] (Correct)
Answer:
[tex] \frac{n}{ - 3} - 2 = 8 \\ \frac{n}{ - 3} = 8 + 2 \\ = 10 \\ n = 10 \times - 3 \\ n = - 30[/tex]

A mechanic has sockets with sizes shown below. Write each fraction in the correct box.
Missing Details:
Write each fraction in the correct box.
1/8in, 5/8in, 8/16in, 9/16in, 15/16in, 5/6in
Less than: 1/2inch,
Equal to: 1/2inch
Greater than: 1/2inch
Answer:
Less than: 1/2inch---> 1/8 in
Equal to: 1/2inch ---> 8/16 in
Greater than: 1/2inch ---> 5/8in, 9/16in, 15/16in, 5/6in
Step-by-step explanation:
Given
Sizes: 1/8in, 5/8in, 8/16in, 9/16in, 15/16in, 5/6in
Required
Match the size with the correct inequalities
Convert 1/2in to decimal
[tex]\frac{1}{2}\ in = 0.5\ in[/tex]
Next, we convert each size to decimal and compare the decimal equivalent to 0.5in
Convert 1/8in to decimal
[tex]\frac{1}{8}\ in = 0.125\ in[/tex]
0.125 is less than 0.5in
Convert 5/8in to decimal
[tex]\frac{5}{8}\ in = 0.625\ in[/tex]
0.625 is greater than 0.5in
Convert 8/16in to decimal
[tex]\frac{8}{16}\ in = 0.5\ in[/tex]
0.5 is equal to 0.5in
Convert 9/16in to decimal
[tex]\frac{9}{16}\ in = 0.5625\ in[/tex]
0.5625 is greater than 0.5in
Convert 15/16in to decimal
[tex]\frac{15}{16}\ in = 0.9375\ in[/tex]
0.9375 is greater than 0.5in
Convert 5/6in to decimal
[tex]\frac{5}{6}\ in = 0.833\ in[/tex]
0.833 is greater than 0.5in
So, we have:
Less than: 1/2inch---> 1/8 in
Equal to: 1/2inch ---> 8/16 in
Greater than: 1/2inch ---> 5/8in, 9/16in, 15/16in, 5/6in

Use Desmos to graph the following system of equations. Paste a link to your Desmos graph.
y = 2/3x-2
y = 2/3x+5
How many solutions does the graph have?
Answer:
it has 5 hopefully this helps you with work
Answer:
No solutionsStep-by-step explanation:
Given lines:
y = 2/3x-2 y = 2/3x+5These have same slopes of 2/3 and therefore are parallel, so no intersection. There is no solution if lines don't intersect.
The graph is attached as well to show lines are parallel.
Find the values of b such that the function has the given minimum value.
f(x) = x2 + bx − 21;
Minimum value:
−70
Answer: b = 14.
Step-by-step explanation:
We have the function:
f(x) = x^2 + b*x - 21
The minimum of a quadratic function will be at the vertex, and the vertex is at the value of x such that:
f'(x) = 2*x + b = 0
then the vertex is at:
x = -b/2
Then the minimum of the function f(x) will be:
f(-b/2) = (-b/2)^2 + b*(-b/2) - 21
and we know that the minimum value is -70, then:
f(-b/2) = -70 = (b^2)/4 - (b^2)/2 - 21
Now we need to solve this equation for b.
-70 = (b^2)/4 - (b^2)/2 - 21
-70 = -(b^2)/4 - 21
-70 + 21 = -(b^2)/4
49 = (b^2)/4
49*4 = b^2
196 = b^2
√196 = b = 14
The value of b is 14.

The population of deer in a forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 percent per year.
Based on this prediction, about how many years will it take for the population to double in size?
Use the equation P = P.(1 + r)
in which Po represents the initial population size, rrepresents the growth rate, trepresents the number
of years, and Prepresents the final population size.
A.
5.0 years
B.
1.8 years
OC. 0.3 year
OD.
3.8 years
Answer:
35 years
Step-by-step explanation:
Given that:
Current deer population, P0 = 800
Growth rate = 20% yearly
For the population to double in size, P = 2 * P0 = 2 * 800 = 1600
t = number of years
Using the relation :
P =P0(1 + r)^t
1600 = 800(1 + 0.2)^t
1600 / 800 = (1.02)^t
2 = (1.02)^t
t = log2 / log(1.02)
t = (0.3010299 / 0.0086001)
t = 35.003069
t = 35 years

A standard sheet of paper in the United States is 11 inches long and 8.5 inches wide
Each inch is 2.54 centimeters. How long and wide is a standard sheet of paper in centimeters?
A standard sheet of paper in Europe is 21.0 cm wide and 29.7 cm long. Which has the greater area, the standard sheet of paper in the United States or the standard sheet of paper in Europe?
Answer:
Step-by-step explanation:
1 in = 2.54 cm
Part (a)
Answer: 8.268 in
Part (b)
Answer: 11.693 in
Part (c)
In SI units standard-sized paper is 21.0 cm by 29.7 cm, which is equivalent to 8.268 in by 11.693 in.
Answer: 8.268 in by 11.693 in.
Part (d)
The U.S sized standard paper is 8.0 in by 11.0 in. Therefore the SI (internationally) sized paper is longer.
Part (e)
If the U.S> adopts the SI standard for letter-sized paper, both the width and length of standard paper will have to be increased. Therefore letter-sized paper will occupy a larger area and will be heavier if the thickness and density do not change.
g(1) if g(x) = x^2 + 1.
Answer:
g(1)=2
Step-by-step explanation:
g(1)= 1^2+1 (you fill in 1 for x)
g(1)=1+1 (1 to the second power is 1 times 1 which is 1 and then you add 1 and 1)
g(1)=2
