Solve for x.
8.7 + X = 7
=
1.1
x = [?]
Answer:
-1.7
Step-by-step explanation:
8.7 + X =7
incorporate the shoes and socks method. We must do the opposite of what is being done. If we are adding X, we will subtract X on both sides leaving you with 8.7=7-x. We want X on one side of the equation so now we take the 8.7 and subtract on both sides giving 7-x-8.7. we must add X on both sides so we can have a X on one side thus X= 7-8.7. we can ordinary subtract and will give us -1.7.
X=-1.7
8.7+(-1.7) =7
find the HCF of 50and70 by using euclids algorithm
Answer:
10
Step-by-step explanation:
To find,
HCF of 50 & 70 using Euclid's Division Algorithm.
Solution,
HCF(50 & 70) -- 70 = 50 × 1 + 20.
50 = 20 × 2 + 10
20 = 10 × 2 + 0.
Therefore their HCF is 10.
Answer:
10
Step-by-step explanation:
According to Euclid's Algorithm, c = dq + r , 0 ≤ r < d (where r is the remainder)
As 70 > 50, c = 70 and d = 50
Substituting values of c and d:
70 = (50 x 1) + 20
⇒ 50 = (20 x 2) + 10
⇒ 20 = (10 x 2) + 0
Therefore, the HCF is 10

Step-by-step explanation:
about circle R
arc angle MP = angle MRP = 78°
angle M = angle LMP.
according to the rules of inscribed angles, LMP is half of angle LRP.
LRP + MRP = 180° because together they cover the whole LM segment (half-circle).
LRP = 180 - MRP = 180 - 78 = 102°
so, LMP = angle M = 102/2 = 61°
also circle R (with arc ULNP)
the arc ULNP = arc UL + arc LN + arc NP = 160°
due to the congruent definition of JU and MP we know that arc UL = arc NP.
and we know arc LN = arc JM = 18°.
so,
160 = 2×arc NP + 18
142 = 2×arc NP
arc NP = 71° = arc UL
now, because arc MP + arc LP = 180 (half-circle),
arc MP = 180 - arc LP = 180 - arc LN - arc NP =
= 180 - 18 - 71 = 91°
about the circle R with 2 congruent chords :
the second answer : they are equidistant from R (the center of the circle).
about circle W
arc MK + arc KL = 180° (half-circle).
and we see
arc HL = arc KL = 53°.
so,
arc MK + 53 = 180°
arc MK = 180 - 53 = 127°
about circle M
arc QTS = 204°.
therefore, arc QRS = 360 - arc QTS = 360 - 204 =
= 156° = angle QMS.
according to the rules of inscribed angles
angle QTS = QMS/2 = 156/2 = 78°

How do I solve for x and y?
Answer:
x = 69y = 21Step-by-step explanation:
To solve for x and y, take advantage of the relationships between angles and diagonals in a rhombus. Each diagonal bisects the vertex angle, and the acute angles in each right triangle are complementary.
__
The angles created by the diagonal at the lower left vertex are congruent:
y° = 21°
__
The angles x° and y° are complementary:
x° = 90° -21°
x° = 69°

The amount which Brandon have saved in interest by consolidating the two balances on the card with the lower interest rate is $256.12.
What is monthly payment?Monthly payment is the payment which has to paid against the loan amount or the borrowed money calculated with interest rate.
It can be calculated with the following formula.
[tex]M=P\left (\dfrac{r}{1-(1+r)^{-nt}}\right)[/tex]
Here, (P) is the principal amount, (r) is the interest rate and (t) is time.
Brandon has two credit cards and would like to consolidate the two balances into one balance on the card with the lower interest rate.

Cards Amount APR Monthly PaymentCard a $1,463.82 13% $24.60Card b $1,157.98 17% $22.14
Interest rate for the card a is,
[tex]r=\dfrac{13}{12\times100}=0.01083[/tex]
The time period is 8 years and there are 12 months in one year. Thus, the monthly payment of card A will be,
[tex]M=1157.98\left (\dfrac{0.01083}{1-(1+0.01083)^{-12(8)}}\right)\\M=19.47[/tex]
In the 8 years, there is total 96 monthly payments. Thus, the total payment by card A is,
[tex]P_a=19.47\times96=1869.12[/tex]
For the card B the monthly payment is $22.14. Thus the total payment by card B is,
[tex]P_b=22.14\times96=2125.44[/tex]
The difference in the payment is,
[tex]d=2125.44-1869.12\\d=256.12[/tex]

Answer:
y=4x-9
Step-by-step explanation:
Slope-intercept form is y=mx+b where y is the y vale, m is the slope, x is the x value and b is the y-intercept.
We need to find the slope and y-intercept.
To find slope we will do rise/run
If we start from (3,3) and go up 4 and over 1 we get to (4,7)
4 over 1 is also 4
So m=4 or slope is 4
Now lets find the y-intercept
We can plug in our values and solve for b
3=4*3+b
3=12+b
-9=b
y-intercept is -9
so our answer will be y=4x-9
Answer:
y = 4x -9
Step-by-step explanation:
The equation of this line is requested in slope-intercept form. The y-intercept is off the bottom of the graph, so we much develop the equation from what we can see.
Exact values are best determined from points where the line crosses grid intersections. We observe two of those are (1, -5) and (2, -1). The slope formula can tell us the slope:
m = (y2 -y1)/(x2 -x1)
m = (-1 -(-5))/(2 -1) = 4/1 = 4
The formula for the y-intercept can be used with the first point:
b = y -mx
b = -5 -4(1) = -9
Then the equation of the line y = mx +b is ...
y = 4x -9
Ms. fudge recently gave an algebra 1 test. the scores were normally distributed with a mean of 74 and a standard deviation of 8. find each of the following. write as a percent.
Using the Empirical Rule, it is found that there is a 68% probability that a student scored between 66 and 82.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, considering the mean of 74 and the standard deviation of 8, we have that:
74 - 8 = 66
74 + 8 = 82.
Hence, there is a 68% probability that a student scored between 66 and 82.

VOL_cone is 70.7
which is LESS THAN
the vol of cylinder. VOL_cyl is 71.6
Step-by-step explanation:
Volume of a cone:
V= (1/3)pi•r^2 • h
=(1/3)pi•3^2 • 7.5
= 70.7 cubic inches
(rounded to tenths this is the same if you use a pi key on the calculator or if you use 3.14)
The Volume of a cylinder:
V = pi•r^2 • h
= pi• 2.25^2 • 4.5
= 71.6 cubic inches
(more accurate with pi key, using 3.14 it rounds to 71.5)
The last blank could be the words "less than" but if they are asking for a fraction or percent, calculate by putting the big number on the bottom and the smaller number on top.

Answer:
14x + 23
Step-by-step explanation:
The lengths of three sides of a triangle are 5x + 9 feet, 2x + 14 feet, and 7x feet.
The perimeter of a triangle: the sum of all of its sides.
5x + 9 + 2x + 14 + 7x
14x + 23
It's the expression of the perimeter of the triangle. Once you will be asked to find x, you'll probably be given the exact perimeter of the triangle.

Answer:
A: geometric; 4 times
B: arithmetic: 4 more
Step-by-step explanation:
An arithmetic model is a linear model, where the rate of change is constant. Growth or decay is by a constant amount from one interval to the next.
A geometric model is an exponential model, in which the rate of change is proportional to the amount. Growth or decay is by a constant factor from one interval to the next.
__
A)The equation for the sequence is given in "explicit" form:
[tex]A_n=2^{2n}[/tex]
The exponent can be split so this can be rewritten as ...
[tex]A_n=(2^2)^n=4^n[/tex]
If this were written in recursive form, it would look like ...
[tex]A_0=1,\ A_n=4\times A_{n-1}[/tex]
The fact that terms are related by a constant factor tells you the model is geometric. The factor tells you each hour the population is 4 times what it was in the previous hour.
__
B)The given equation is in "recursive" form. It tells you each term is 4 more than the previous one. This constant difference between terms means the model is arithmetic.
