Which set of equivalent measures does not indicate that two triangles must be congruent?
A anglo-angle-angle B. side-angle-side
C. angle-side-angle D. angle-angle-side
Answer:
C. angle-side-angle
D. angle-angle-side
Step-by-step explanation:
A triangle is bounded by three sides, thus it has three angle. When two triangles are compared, the length of sides and angles could be similar or not. Thus, the triangle may be congruent or not congruent.
The relationship between congruent triangles can be expressed as regards to their sides, angles, or both.
From the given question, when the three angles of two given triangles are the same, then the two triangles are congruent. This relationship can be expressed as Angle-Angle-Angle.
Also, when two triangles have two equal sides and an included angle to be equal (i.e Side-Angle-Side), then they are congruent.
Biologists have found that the number of chirps some types of cricket make per minute depends upon the temperature this relationship can be represented by a linear function when the temperature is 60° Fahrenheit to crickets chirp 92 times per minute if it is 75 Fahrenheit they will chirp 152 times per minute what will the number of chirps be per minute if the temperature is 80 degrees Fahrenheit
Answer: Crickets make 172 chirps/min at 80 degrees Fahrenheit
Step-by-step explanation:
Step 1
Using the point slope formulae for Linear functions , we have that
y - y1 = m(x - x1)
where x and y are two points representing the temperature and chirps /min respectively
And
m= slope
Step 2 : Finding the slope , m
where x1=60
y1=92
x2= 75
y2=152
m= (y2-y1)/ (x2-x1)
= (152- 92)/(75-60)
=60/15 =4
Bringing down the point/slope formula and imputing the known values to find our equation to show the relationship cricket make per minute and the temperature
y - y1 = m(x - x1)
y - 92= 4(x - 60)
y - 92 = 4x -240
y = 4x - 240 + 92
y = 4x - 148
Step 3
To find the number of chirps be per minute (y) if the temperature is 80 degrees Fahrenheit( x)
y = 4(80) - 160
y = 320 - 148
y = 172 chirps/min at 80 degrees Fahrenheit

Two out of 8 kittens have white feet. What percentage of the litter had white feet?
Answer:
2 out of 4
Step-by-step explanation:
Answer:
Is 25%
Step-by-step explanation:
2/8=1/4 1/4 as a percent is 25%
х+бу =20
x+3y = 14
Solve the simultaneous equations
х+6у =20
x+3y = 14 //-1
-----------------------
х+6у =20
-x-3y = -14
------------------------
3y = 6
y = 2
x + 3(2) = 14
x + 6 = 14
x = 14 - 6
x = 8
The proportion
75/w = 150/100 can be used to find the whole, w.
Use the language of percent to explain whether
w is less than or greater than 7
Answer:
w is greater than 7
Step-by-step explanation:
Given
[tex]\frac{75}{w} = \frac{150}{100}[/tex]
Required
Determine if w is less than or greater than 7
[tex]\frac{75}{w} = \frac{150}{100}[/tex]
Cross Multiply
[tex]w * 150 = 75 * 100[/tex]
[tex]150w = 7500[/tex]
Solve for w
[tex]w = \frac{7500}{150}[/tex]
[tex]w = 50[/tex]
Convert to percentage
[tex]w = 50 * 100\%[/tex]
[tex]w = 5000\%[/tex]
w is greater than 7 because 50 or 5000% is greater than 7

Fernie has $400 he received for his birthday. Evey month ,$32 is removed from his account to go to his college savings . (no other transactions are made). Create and solve an equation to find the number of months it takes for the account balance to reach $176.
HELPPPPPPPP
Answer:
y = 400-32x where y is the amount left and x is the number of months
Step-by-step explanation:
y = 176$
x =?
176 = 400 -32x
32x = 400 - 176
32x = 224
x = 7 months

Tell whether a triangle can have sides with lengths 3, 4, and 8.
Answer:
Yeah a triangle can have any measurements as long as it makes sense. Your not gonna put the mesurment 8 on the shortest side but the longest, and then the next longest will be 4, and then 3 as the shortest.
Step-by-step explanation:
You'd be lookin for a scalene triangle, Acute triangle, or obtuse triangle, (I'm not so sure about a right triangle, but you might be lookin at that too)
I hope this helps!!!!

A retail store makes k%
profit on the selling price. What is the least integer value of k
that will enable the store to make a profit of at least 30%
of the cost of the item?
Please answer as soon as possible. i do not understand. me and my friends dont uderstand.
Answer:
10
Step-by-step explanation:
The store wants to make a 20% profit:
Multiply the cost of the toy by 1.20 ( cost plus 20%).
6.25 x 1.20 = $7.50
This means when the toy is sold at 25% off, it needs to be $7.50 to make the 20% profit.
When the item is 25% off, that means it would sell for 75% of the original price.
Now to find what the price needs to be before the 25% off divide the profit price by 75%
7.50 / 0.75 = $10
K = $10

Can someone pls help me
9514 1404 393
Answer:
y > 1/2x + 2
Step-by-step explanation:
The points shown on the line are separated by a "rise" of 1 unit vertically, and a "run" of 2 units horizontally. Its slope is rise/run = 1/2.
The line crosses the y-axis at y=2, so the y-intercept is 2.
The boundary line is then ...
y = mx + b . . . . . . . where the slope is m and the y-intercept is b
y = 1/2x + 2 . . . . . . the equation of the boundary line
__
The line is dashed, and the shaded area is above the line, where y-values are greater than the y-value on the line. Then the y-values on the line are NOT included in the solution set. The inequality is ...
y > 1/2x + 2
