Answer:
16 sweets
Step-by-step explanation:
Number of sweet that Sekhar had = x
Sweets given to Renu = (1/4) of x = [tex]\frac{1}{4}x[/tex]
Sweets given to Raji = 5
Remaining sweets = 7
[tex]x = \frac{1}{4}x +5 + 7\\\\x -\frac{1}{4}x = 12\\\\\frac{4*x}{1*4}x-\frac{1}{4}x = 12\\\\\frac{4x}{4}-\frac{1}{4}x= 12\\\\\frac{3x}{4}=12\\\\x = 12*\frac{4}{3}\\\\x=4*4\\\\x=16[/tex]

A linear sequence (i.e. where the 1st difference is always the same) has 5th term 6 and 92nd term 354. What is the 57th term?
Answer:
I dont know xDDDDDDDDDD
Answer:
a₅₇ = 214
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₅ = 6 and a₉₂ = 354 , then
a₁ + 4d = 6 → (1)
a₁ + 91d = 354 → (2)
Subtract (1) from (2) term by term to eliminate a₁
0 + 87d = 348
87d = 348 ( divide both sides by 87 )
d = 4
Substitute d = 4 in (1) and solve for a₁
a₁ + 4(4) = 6
a₁ + 16 = 6 ( subtract 16 from both sides )
a₁ = - 10
Then
a₅₇ = - 10 + (56 × 4 ) = - 10 + 224 = 214
What is the y-intercept of the line that is perpendicular to y = −3x − 5 and passes through the point (−3, 7)?
NEED BEFORE 11:59 ASAP
Answer:
b=8
Step-by-step explanation:
Perpendicular lines are negative and reciprocal; when you multiply the slopes together, the result is -1.
we are given the line y=-3x-5
we need to find the slope of the new line. To do that, we can use this equation:
-3m=-1
divide by -3 on both sides
m=1/3
so the slope of the perpendicular line is 1/3
We can write our line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, which is what we need
so far our equation is:
y=1/3x+b
we need to find b
we can substitute the point (-3,7) into the equation, since the line will pass through it to solve for b
so:
7=1/3(-3)+b
7=-1+b
8=b
so the y intercept of the line is 8; as a point it's (0,8)
hope this helps!
2.In ABC, BD is perpendicular to AC. The dimensions are shown in centimeters.
What is the length, in centimeters, of AC?
ASAP BEFORE TOMORROW 11
Answer:
AC = 12
Step-by-step explanation:
From the question, we have that BD is perpendicular to AC
This means that it is at 90 degrees to the base
so we have two similar right triangles
Let us use Pythagoras’ theorem to get the measure of one of the legs (AD and DC)
Let us call the leg x
We have the Pythagoras’ theorem stating that the square of the hypotenuse (the side facing the right angle; 10 here) is equal to the sum of the squares of the two other sides
10^2 = x^2 + 8^2
100 = x^2 + 64
x^2 = 100-64
x^2 = 36
x = √36
x = 6
AD = DC = 6
AC = 2 * AD
AC = 2 * 6
AC = 12

Use f(x) and g(x) to answer the question.
f(x) = x +4
g(x) = x – 2
What is the product (fºg)(x)?
Answer:
Correct answer is the first one x^2 + 2x - 8
because (x + 4) (x - 2)
= x ^2 + 4x - 2x - 8
= x^2 + 2x - 8

area->60m²+20m²=80m²
Car A travels 20 mph faster than Car B. In the same time that Car A travels 208 mi, Car B travels 156 mi. Find their speeds. The speed of Car A is and the speed of Car B
Step-by-step explanation:
Assuming the speed of car B to be x and the speed of car A to be x+20
156 = 208
x. x+20
156(x+20)= 208x
156x+3120=208x
3120=208x-156x
3120=52x
x=60
The speed of car A is (x)= 60
The speed of car B is(x+20)= 80
Answer:
[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:equationPEMDASlet's solve:let the speed of car A be A
let the speed of car B be B
according to the first condition:
[tex]\quad A=B+20[/tex]
according to the second condition:
[tex]\quad 156(A)=208B[/tex]
[tex]\text{substitute the value of A into the equation:}\\ \sf \implies 156(B+20)=208(B)[/tex][tex]\sf distribute:\\ \implies 156B+3120=208B[/tex][tex] \sf \: substract\: 156B \: from \: both \: sides : \\ \implies \: 156 B -156 B + 3120 = 208 B - 156 B \\ \implies \: 3120 = 52 B[/tex][tex] \sf divide \: both \: sides \: by \: 52 : \\ \implies \frac{52B}{52} = \frac{3210}{52} \\ \therefore \: B = 60[/tex]therefore
[tex]\text{the speed of car A is 60+20=80}[/tex]
Solve the right triangle. Round decimal answers to the nearest tenth. what is angle a and angle b
Answer:
b = 12.6
Step-by-step explanation:
a*2 + b*2 = c*2
6*2 + b*2 = 14*2
36 + b*2 = 196
Subtract 36 from both sides
36 + b*2 = 196
-36 -36
b*2 = 160
Find the square root of both
b = 12.64911064 or 12.6
Yesenia buys milk to make milkshakes for all her friends. She buys 1 quart of milk and
1/2 gallon of milk. How many cups of milk does she buy?
Answer:
12 CUPSExplanation:
1 quart = 4 cups
1 gallon = 16 cups
Yesenia buys 1 quart -> 4 cups
AND 1/2 a gallon -> 8 cups
4 cups from quart + 8 cups from 1/2 gallon = 12 cups total!
A regular pentagon with sides each measuring 6 inches is dilated by a scale factor of 3.1. What is the length of each side of the dilated pentagon?
Answer:
18.6inches
Step-by-step explanation:
Given the length of a side of a pentagon to be 6 inches.
If this length is dilated by a factor of 3.1, the new length will be;
New length = Old length * dilation factor
New length = 6 * 3.1
New length = 18.6inches
Hence the length of each side of the dilated pentagon is 18.6inches

Answer:
So the answer is 2^-3
Step-by-step explanation:
The principle is the same no matter what the base.
Log_2 (7) + Log_2(3/28) - Log_2(6)
+ means multiply
- means divide
Log_2(7 * 3/28 /6)
Log_2(7/6 * 3/28)
Log_2(1/2 * 1/4) 3 divides into 6 twice. 7 divides into 28 four times
log_2 (1/8)
This is equivalent to 2^(-3)
