Determine wether the pair of triangles are similar. Explain your answer.
The three squares below join together to form a right triangle. The area and the perimeter for two of the squares is shown. Find the side length of the largest square.
Answer:
YES
Step-by-step explanation:
by dividing perimeter by 4, we
get the side lengths of 12, 35 and 37.
122 + 352 = 372.
The side length of the largest square is 15 inches.
From the given figure, area of one of the square is 81 square inches and the perimeter of another square is 48 inches.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
We know that, the area of a square = a²
Here, a²=81 square inches
⇒ a=9 inches
The perimeter of square = 4s
⇒ 4s=48
⇒ s = 12 inches
In the given figure, let the hypotenuse of triangle be x
Using Pythagoras theorem, we get
Now, x²=a²+s²
⇒ x²=9²+12²
= 81+144
= 225
So, x=15 inches
Therefore, the side length of the largest square is 15 inches.

Miss Penny inherits £1040
she decides to save some of the money and spend the rest
the ratio of savings to spending money is 5:8
how much does she save and how much does she spend
Answer:
Step-by-step explanation:
first we simplify the ratio
5:8
8/5=1.6
1:1.6 so for every 1 dollar she save she spends 1.6
next we do 1040/1.6=650
1040-650=390
390:650

Solve the linear equation 2(3x + 2) = 2x – 1 + x. State the property that justifies your first step and why you
chose it.
Answer:
x = -5/3
Step-by-step explanation:
2(3x + 2) = 2x - 1 + x
2 × 3x + 2 × 2 = 2x + x - 1
6x + 4 = 3x - 1
3x = -5
x = -5/3

write the equation for this line
If this is for slope-intercept, the equation is: y = 3x + 1
To find the slope, you would find the rise over run ( [tex]\frac{rise}{run}[/tex] ). So, you would start where the graph intersect at the y-axis, which is 1. You would go up 3 times, and right 1 time. So, [tex]\frac{3}{1}[/tex], or 3, would be your slope. To find the y-intercept, you would need to find where the graph intersects at the y-axis, which is 1, so it would be your y-intercept. Plug them into the y = mx + b formula and the answer is y = 3x + 1.

The length of a ribbon roll is 2.5 m. If 50 cm has been used from it, how much is left?
Answer:
200 cm (or 2 meters) or 80% of the original 250 cm is left. let me know if you have any questions.
Step-by-step explanation:
I'm not sure if that's asking for an exact amount or percent, so I will do both.
The trick either way is to match units. we have meters and centimeters. You could make either one match the other. so 2.5 m is 250 cm and 50 cm is .5 m.
You do have to know how many centimeters is in a meter, but once you know that you can set up unit conversions, which are super simple.
there are 100 cm in a m. a unit conversion is basically a fraction that cancels out units. starting with 2.5 m we want to cancel out m so the fraction we use has the m part in the denominator. so 2.5m * (100 cm)/(1 m). (100 cm)/(1 m) is the unit conversion, and just like variables the m in the denominator cancles out the m in the starting value so it turns into 2.5 * 100 cm/1 = 250 cm.
similarly to go from 50 cm to meters you make the unit conversion have cm in the denominator. so 50 cm * (1 m)/(100 cm) = .5 m. again, the cm int he denominator cancels out the cm in the unit being multiplied. Let me knwo if this is still not clear.
Anyway, now we have the numbers we need. let's make them all cm, I think using the smallest unit is usually easiest. so that's 250 cm total and 50 cm used.
In pure numbers, that means 200 cm is left (which is 2 meters) after 50 cm gets used.
percents is a little trickier. if 250 is 100% then 50 is 20%, which you can get by doing 50/250. if you do not know, a fraction a/b gives you the percent a is of b. Or rather it gives you a decimal, and if you multiply it by 100 it gives you the percent.
anyway, if 20% is used then 80% is left. if you did 200/250 you would get that.
