Answer:
45
Step-by-step explanation: 180-90=90
90/2=45
Answer:
x= 45
Step-by-step explanation:
There are 180 degrees in a triangle
The box in the corner is 90
180-90 = 90
There are 90 degrees left
The lines means that the two sides are equal so the angles must be equal
The two angles are x and x
x+x = 90
2x=90
Divide by 2
2x/2 = 90/2
x = 45

24m
22m
Answer:
You distribute the 2 to the m=2m
Then you distribute the 2 to the 11 which gives you 22
ANSWER: 2m+22
Rationalise the denominator. Simplify your answer fully. 22 /√ 15 + 2
Answer: [tex]\frac{22\sqrt{15}-44 }{11}[/tex]
Step-by-step explanation:
[tex]\frac{22}{\sqrt{15}+2 } *\frac{\sqrt{15}-2}{\sqrt{15}-2} =\frac{22\sqrt{15}-44 }{(\sqrt{15})^2-(2)^2 } =\frac{22\sqrt{15}-44 }{15-4} =\frac{22\sqrt{15}-44 }{11}[/tex]

Harry’s teacher begins each class with a head problem. One day, Harry is late to class so he misses the beginning of the problem. The instructor ends with “Take the absolute value of your number. Your answer shouldn’t be zero. If your answer is positive, raise your right hand. If your answer is negative, raise your left hand.” Even though Harry has missed all the computations, can he still get the answer correct? Why or why not? (Assume Harry is an intelligent guy, and does his homework.) Which hand should Harry raise? Why?. *
A.Harry knows enough about solutions to absolute value that he raises his right hand to show his solution is positive
B.Harry knows enough about solutions to absolute value that he raises his left hand to show his solution is negative
C.Harry cannot determine the solution if he missed the question at the begining

How do you write 3.0 × 10^2 in standard form?
Answer:
300
Step-by-step explanation:
First you would find 10^2, which is 100. Then you just multiply 100 by 3.0 and get 300 :)
Answer:
To write in standard form, we have to move the decimal point in 3.14 over 2 places to the left since our exponent is −2. This gives us our answer of 0.0314.
I might be wrong.
The number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.
There were 10{,}00010,00010, comma, 000 people using the older version of the spreadsheet program when the new version first came out. The number of people still using the older version decreases by 20\%20%20, percent every 666 months.
Answer:
The decrease in the use of older version is given by,[tex]y = 10000 \cdot0.60^{t}[/tex].
Step-by-step explanation:
It is provided that the number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.
The exponential decay function is given as follows:
[tex]y=a(1-r)^{t}[/tex]
Here,
y = final value
a = initial value
r = decay rate
t = time taken
It is provided that there were 10,000 people using the older version of the spreadsheet program when the new version first came out. And the number of people still using the older version decreases by 20% every 6 months.
So, every half-yearly the decrease in the number of people using the older version is 20%. This implies for a year the decay rate is 40%.
Then the decrease in the use of older version is given as follows:
[tex]y=10000(1-0.40)^{t}\\\\y=10000\cdot 0.60^{t}[/tex]

I WILL GIVE YOU BRAINLIEST!!!!! The first side of a triangle is three times as long as the second side, and the third side is 50 cm shorter than the first side. Find all sides of the triangle if its perimeter is 370 cm. PLS HELP ME!!!!!!!
Answer:
The first side of the triangle = 180 cm
The second side of the triangle = 60 cm
The third side of the triangle =130 cm
Step-by-step explanation:
To solve this, we will follow the steps below;
First, re-write the question in a mathematical format and then solve;
let a=the first side of the triangle
b=the second side of the triangle and
c=the third side of the triangle
"The first side of a triangle is three times as long as the second side" can be re-write mathematically as:
a=3b ------------------------------------------------(1)
"the third side is 50 cm shorter than the first side" can be re-write as :
c=a-50-----------------------------------------------(2)
"perimeter is 370" can be re-write as:
a + b + c = 370 --------------------------------------(3)
from equation (2), make b subject of the formula; a= 3b
b=a/3 ------------------------------------(4)
substitute equation (2) and (4) into equation (3)
a + b + c = 370
a+[tex]\frac{a}{3}[/tex] + a-50 = 370
add 50 to both-side of the equation
a+[tex]\frac{a}{3}[/tex] + a-50 + 50= 370 + 50
a+[tex]\frac{a}{3}[/tex] + a= 420
[tex]\frac{3a + a + 3a}{3}[/tex] = 420
[tex]\frac{7a }{3}[/tex] = 420
multiply both-side of the equation by 3
[tex]\frac{7a }{3}[/tex] ×3= 420×3
7a = 1260
Divide both-side of the equation by 7
[tex]\frac{7a}{7}[/tex] = [tex]\frac{1260}{7}[/tex]
a= 180
from equation (4) b = a/3
b = 180/3 = 60
from equation (2) c= a- 50
c= 180 - 50
c= 130
a= 180 cm
b = 60 cm
c= 130 cm
Therefore,the first side of the triangle = 180 cm
the second side of the triangle = 60 cm
the third side of the triangle =130 cm

Answer:
The first option, the mayor will lose by a large percentage.
Step-by-step explanation:
If you look at the numbers, You can see that the two best answers which are excellent and satisfactory are low, and in total equal 28.
Being compared to the lower ratings which are needs improvement and unsatisfactory are high, and in total equal 52.
Seeing this, this shows that the mayor will lose the election the with more than half of the people voting for someone else.
All the other options excluding the first one, say that he will win by a close call, a big percent, or a close call again.
which just leaves the first option saying that he will lose by large percent, which is true.
Mr. Franco's records show that 44% of his students bring their own lunches to school. What is the percent and decimal of the students who DO NOT bring their own lunches.
Answer:
Percentage 56%
Decimal 0.56
Step-by-step explanation:
As percentages are out of 100, to work out the people who did not bring their own lunches you would simply minus the percentage of people that do which is 44 by 100, this gives you 56. this is because subtracting it from 100 we are removing the people that did from the total and so will leave us with the percentage of people that did not.
To work out the percentage who did not bring in their own lunches as a decimal you would divide the percentage of 56 by 100, this gives you 0.56. This is because percentages are out of 100%.
1) Minus 44 from 100.
[tex]100-44=56%[/tex]
2) Divide 56 by 100.
[tex]56/100=0.56[/tex]
Find the area of the irregular figure. Round your answer to the nearest hundredth if necessary.
Answer:
Step-by-step explanation:
Area of the figure = Area of semicircle + area of rectangle
Area of semicircle:
d = 14 mm
r = 14/2 = 7 mm
Area = (1/2)πr²
[tex]=\frac{1}{2}*\frac{22}{7}*7*7\\[/tex]
=11 *7
= 77 mm²
Area of rectangle:
length = 14 mm
Width = 10 mm
Area = length *width
= 14 * 10
= 140 mm²
Area of the figure = 77 + 140 = 217 mm²
