Hey there!
We can see we are subtracting 2 every time, and we have 95 terms left fo figure out, so we multiply 95 by 2 and get 190, then subtract that from 15.
15 - 190 = -175, therefore, that's the the 100th term.
Have a terrifcly amazing day!
Answer:
you keep subtracting 2 every time, that's the pattern
Pythagorean theorem - please help
answer:
x = 4[tex]\sqrt{2}[/tex] or 5.6568
step-by-step explanation:
know the formula and plug informula: a^2 + b^2 = c^2
now plug in what we havewhatever the RIGHT ANGLE points to is the HYPOTENUSE or cthe other two sides are the "legs" or a and ba^2 + b^2 = c^2
7^2 + b^2 = 9^2
49 + b^2 = 81
b^2 = 32
b = 4[tex]\sqrt{2}[/tex]
in this case, b would be used as xx = 4[tex]\sqrt{2}[/tex] or 5.6568 (exact value)
Find the distance between C(-5,4) and Q(2,0)
9514 1404 393
Answer:
√65 ≈ 8.06
Step-by-step explanation:
The distance formula is used for the purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)
d = √65 ≈ 8.0622577
The distance between C and Q is √65, about 8.06 units.

y - 7.74 = 9.1
solve for y
Answer:
y = 16.84
Step-by-step explanation:
y - 7.74 = 9.1
=> y = 9.1 + 7.74
=> y = 16.84
If HF=4x+9, EF=5x + 3, and FG EH, solve for X (pictures included)
Answer:
[tex]\boxed{\textsf{ The value of x is \textbf{6}}}.[/tex]
Step-by-step explanation:
Given that in the given figure , HF = 4x + 9 and EF = 5x +3 . And FG [tex]\perp[/tex] EH . we need to find the value of x .
And here the two triangles must be congruent to each other . That is ,
[tex]\sf \triangle EGF \cong HGF [/tex]
So we can say that
EF = HF ( by cpct )Using this equation we have ,
[tex]\sf\implies EF = HF \\\\\sf\implies 4x +9=5x+3\\\\\sf\implies 4x - 5x = 3-9\\\\\sf\implies -x=-6\\\\\sf\implies \boxed{\pink{\sf x = 6}}[/tex]

you do 90 sit-ups in 2 minutes .Your friend does 126 sit-ups in 2.8 minutes .Do these rates form a proportion?
Brainiest
Answer:
Yes
Step-by-step explanation:
90/2 = 45
126/2.8 = 45
Therefore these rates do form a proportion
Step-by-step explanation:
so we will find the number of sit-ups the friend should do, if it is a direct proportion
let the number of friend's sit-ups be x
2 : 2.8
90 : x
cross multiply
we get x=126 sit-ups
so the rates do form a (direct) proportion

Equation that has a slope of -4 and passes through the point (-2, 2) show work too
Answer:
y=-4x-6
Step-by-step explanation:
y=mx+b, where m is the slope and b is the y-intercept
Slope is given as -4, so:
y=-4x+b
To find b, sub in the point we were given (-2,2):
2=-4(-2)+b
2=8+b
b=2-8=-6
So we have: y=-4x-6
a class has 28 students the ratio of girls to boys is 4:3 how many girls are in the class
Answer:
What are the answer choices?
Step-by-step explanation:
Answer:
16 girls
because 4+3=7 when you add the ratios which is the total number of parts in the ratio.
then you divide 28/7=4 which is equal to one part
then you multiply 4x4 because you are trying to find out the number of girls and there are 4 part girls in the ratio. 4x4=16 so therefore there are 16 girls in the class
what is the answer to this question you will need to be good at maths and you need to know how to do inequalities
28>6x-2
Answer:
5 > x
Step-by-step explanation:
28 > 6x -2
(add 2 to both sides)
30 > 6x
(divide through by 6)
5 > x
Answer:
x < 5
Step-by-step explanation:
Given
28 > 6x - 2 ( add 2 to both sides )
30 > 6x ( divide both sides by 6 )
5 > x , that is
x < 5

1.
y = x + 11 y = 1 + 11
y = 12x y = 12
x + 11 = 12x
11 = 11x
x = 1
(1, 12)
2.
y = 2x - 1
y = x + 1
2x - 1 = x + 1
x = 2
y = 2(2) - 1
y = 3
(2, 3)
3.
4x + 6 = 2x +2
2x = - 4
x = -2

The world's fastest man, Usain Bolt,
sprinted an amazing 62. 64 meters in 6
seconds. At this rate, how many meters
did Usain Bolt travel in 4 seconds? 1
Answer:
41.76 meters
Step-by-step explanation:
Usain Bolt's speed = [tex]\frac{62.64}{6}[/tex]= 10.44m/s
=> In 4 seconds Usain Bold can run: 10.44 x 4 = 41.76m
The figure below shows a line graph and two shaded triangles that are similar:
A line is shown on a coordinate grid. The x axis values are from negative 20 to positive 20 in increments of 4 for each grid line. The y axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 16, negative 4, and 0, 0, and 16, 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to negative 8, negative 2 labeled as A, one leg is from 0, 0 to 0, negative 2, and the second leg is from 0, negative 2 to negative 8, negative 2. Another shaded right triangle is formed with the hypotenuse from negative 8, negative 2 to negative 12, negative 3 labeled as B, one leg is from negative 8, negative 2 to negative 8, negative 3, and the second leg is from negative 12, negative 3 to negative 8, negative 3.
Which statement about the slope of the line is true?
A. The slope from point O to point A is fraction 1 over 4 times the slope of the line from point A to point B.
B. The slope from point O to point A is 4 times the slope of the line from point A to point B.
C. It is 4 throughout the line.
D. It is fraction 1 over 4 throughout the line.
The answer should be D

11. The slope of a line is 1/5. Label the two right
triangles with dimensions that would allow the
triangles to lie on the same line.
Answer:
Step-by-step explanation:
If the slope is 1/5, we can interpret this as rise/run = 1/5. We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:
hypo = +sqrt( 1^2 + 5^2)
In this case we dilate the triangle defined by the slope 1/5:
2/10, 1/10/(1/2), 10/50, etc., all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).
The two right triangles are shown in the graph
What are coordinates?The coordinates in rectangular cartesian system are of the form -
(x, y)
where -
{x} - distance along x - axis.
{y} - distance along y - axis.
Given is the slope of the line as - {m} = 1/5.
Refer to the graph attached. The line -
y = (1/5)x
is plotted. It can be seen that (0, 0) and (10, 2) lie on the line. For two right triangles to lie on the same line, draw two perpendiculars from point (10, 2) along the {x} axis and {y} axis. Refer to the triangles shown in the graph.
Therefore, two right triangles are shown in the graph.
