Answer:
66.7%
Step-by-step explanation:
Given that,
Weight in first five weeks = 4.5 pounds
Weight at eight weeks = 7.5 pounds
We need to find the increase in precentage. The percentage increase in any value is given by :
[tex]\%=\dfrac{\text{final-initial}}{\text{initial}}\times 100\\\\=\dfrac{7.5-4.5}{4.5}\times 100\\\\=66.7\%[/tex]
So, the increase in precentage is 66.7%.

can someone solve 3y − 3 = 2y + 6
step by step
Answer:
[tex]y = 9[/tex]
Step-by-step explanation:
1) Add 3 to both sides.
[tex]3y = 2y + 6 + 3[/tex]
2) Simplify 2y + 6 + 3 to 2y + 9.
[tex]3y = 2y + 9[/tex]
3) Subtract 2y from both sides.
[tex]3y - 2y = 9[/tex]
4) Simplify 3y - 2y to y.
[tex]y = 9[/tex]
Therefor, the answer is y = 9.
Answer:
3y-3=2y+6
3y-2y=3+6 (You will group like terms)
therefore,y=9
5x+ 1/4= 61/4
I’m trying to figure out what x is
I READ IT WRONG AHH
Answer:
3
Step-by-step explanation:
5x + 1/4 = 61/4
-1/4 -1/4
5x = 15
/5 /5
x = 3
Answer:
x=3
Step-by-step explanation:
5x+1/4=61/4
5x=61/4-1/4(61/4-1/4, they have the same denominator so can subtract them with each other)
5x=60/4 (60/4=15)
5x=15
x=15/5
x=3
Tip :to check your answer simply plug in the value and then solve the equation. If both the sides are equal to each other, the answer is most likely correct.

In isosceles triangle JKL, JK KL. If the measure of
angle J is 47°, find the measure of angle K.
*Note: Do NOT include the degree in your answer.
Answer:
86
Step-by-step explanation:
Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.
<L is opposite to side JK, <J is opposite to side KL.
m<J is given as 47°. Therefore,
m<L = m<J = 47°
m<L = 47°
m<J + m<L + m<K = 180° (sum of triangle)
47° + 47° + m<K = 180° (substitution)
94° + m<K = 180°
m<K = 180° - 94°
m<K = 86°

Show your work please answer asap!
40 points.
Answer:
1. Non equivalent, use the distributive property. 5*3=18, 5*4=20, so the equation is now 18y - 20, which is not equal to 15y - 20
2. Same with this one, -4 * -2p = 8p, and -4 * 4 = -16. Now the equation is 8p - (-16), or 8p + 16. Not equivalent.
3. 3*-7x = -21x, and 3*13 = 39. Now the equation is -21x - 39, not equivalent.
4. -6*-4a = 24a, and -6*8 = -48, the equation is now 24a+ (-48), or 24a - 48

find the value of x in the isosceles triangle shown below.
V80
V80
Answer:
Option A. x = 8
Step-by-step explanation:
Please see attached photo.
From the attached photo,
we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:
(√80)² = 8² + y²
80 = 64 + y²
Collect like terms
80 – 64 = y²
16 = y²
Take the square root of both side
y = √16
y = 4
Finally, we shall determine the value of x. This can be obtained as follow:
From the attached photo,
x = 2y
but:
y = 4
Therefore,
x = 2y
x = 2 × 4
x = 8

C. 1 + one-fifth + StartFraction 1 Over 25 EndFraction + StartFraction 1 Over 125 EndFraction
D. StartFraction 1 Over 125 EndFraction + one-fifth + 5 + 125
Answer:
d
Step-by-step explanation:
The partial sum of the geometric series is;
⇒ 125 + 25 + 5 + 1
Option A is true.
What is Geometric series?
Geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
Given that;
The geometric series.
∑ 125 (1/5)ⁿ⁻¹ ; where, n = 1 to 4.
Now, Calculate the partial sum of the geometric series as;
The geometric series = ∑ 125 (1/5)ⁿ⁻¹
Substitute n = 1, 2, 3, 4, we get;
= 125 (1/5)¹⁻¹ + 125 (1/5)²⁻¹ + 125 (1/5)³⁻¹ + 125 (1/5)⁴⁻¹
= 125 (1/5)⁰ + 125 (1/5)¹ + 125 (1/5)² + 125 (1/5)³
= 125 + 25 + 125/25 + 125/125
= 125 + 25 + 5 + 1
Thus, The partial sum of the geometric series is;
⇒ 125 + 25 + 5 + 1
Option A is true.

Answer:
Answer choice one
Step-by-step explanation:
To find the perpendicular line to a given line, just give the reciprocal of the slope and flip the sign.
In this case, you first put the line into the slope-intercept form which would be y=2x-7.
the slope is 2x and the reciprocal is 1/2 and then you flip the sign to be -1/2.
The only one with that slope is answer choice 1.
What percent of the time will the point be in the shaded region
Answer:
29.4%
Step-by-step explanation:
the whole cirlce is 360 degrees which means 100%
to find the percentage of the shaded area, multiply the degrees by 100
⇒ 10.6 x 100 = 10600
then take the product and divide by 360
⇒ 1060 ÷ 360
⇒ 29.44
round to the nearet tenth of a percent
⇒ 29.4
Triangle DEF has vertices D(0,0), E(7,0), and F(3,7).
The altitudes of triangle DEF intersect at point
Answer:
(3, 1.7)
Step-by-step explanation:
The point at which the vertices of a triangle meet is known as the orthocenter of the triangle. The orthocenter passes through the vertex of the triangle and is perpendicular to the opposite sides.
Two lines are perpendicular if the product of their slopes is -1.
The slope of the line joining D(0,0), F(3,7) is:
[tex]m_1=\frac{7-0}{3-0}=\frac{7}{3}[/tex]
The slope of the line perpendicular to the line joining D and F is -3/7. The orthocenter is perpendicular to the line joining D and F and passes through vertex E(7, 0). The equation is hence:
[tex]y-y_1=m(x-x_1)\\\\y-0=-\frac{3}{7} (x-7)\\\\y=-\frac{3}{7}x+3 \ .\ .\ .\ (1)[/tex]
The slope of the line joining E(7,0), and F(3,7). is:
[tex]m_1=\frac{7-0}{3-7}=-\frac{7}{4}[/tex]
The slope of the line perpendicular to the line joining E and F is 4/7. The orthocenter is perpendicular to the line joining E and F and passes through vertex D(0, 0). The equation is hence:
[tex]y-y_1=m(x-x_1)\\\\y-0=\frac{4}{7} (x-0)\\\\y=\frac{4}{7} x\ .\ .\ .\ (2)[/tex]
The point of intersection of equation 1 and equation 2 is the orthocenter. Solving equation 1 and 2 simultaneously gives:
x = 3, y = 1.7
