Answer:
x = 23
Step-by-step explanation:
7x - 11 = 4x + 58
(7x - 4x) - 11 = (4x - 4x) + 58
3x - 11 = 58
3x (- 11 + 11) = 58 + 11
3x = 69
3x/3 = 69/3
x = 23
Find mEC.
5x - 27)
(2x - 5)
D
Answer:
Arc EC = 58°
Step-by-step explanation:
First, find the value of x.
m<D = ½(arc EC) => Inscribed Angles Theorem
Substitute
2x - 5 = ½(5x - 27)
Multiply both sides by 2
2(2x - 5) = 5x - 27
4x - 10 = 5x - 27
Collect like terms
4x - 5x = 10 - 27
-x = -17
Divide both sides by -1
x = 17
Find arc EC:
Arc EC = 5x - 27
Plug in the value of x
Arc EC = 5(17) - 27 = 85 - 27
Arc EC = 58°
Solve the following equation for x: 6( 4X +5) = 3( X +8) +3

suppose 3 years ago Rose was 24 years older than her daughter at present Rose is 5 times as old as her daughter how old will be the daughter in three years time
Answer:
Let Rose be R
Let her daughter be D
"3" yrs ago.
Subtract 3 from their ages
Rose was then (R-3) yrs old.
Daughter ..........(D-3)yrs old
So 3yrs ago.... Rose was 24yrs older than D.
Meaning
R=24+D
Which 3yrs ago can be expressed as
(R-3)=24+(D-3)
R - 3 = 24 + D - 3
R - D=24-3 + 3
R-D=24--------1
Now
At present.
R is 5times as old as Daughter
Meaning R = 5D-------2
Substituting into eqn 1
R-D=24
5D-D=24
4D=24
D=6yrs
Substitute D=6 into any equation of choice to get R
R-D=24
R=24+D
R=24+6
R=30yrs
Now we have Roses's age to be 30yrs and Daughter's age to be 6yrs.
We're asked to find the daughter's age in 3yrs time...
Meaning ....D+3
=6+3 = 9yrs
DAUGHTER WOULD BE 9YRS OLD IN 3YRS TIME.
(t+5)(t+2),make t the subject of the formula
Answer:
t= 2p+5/p-1
Step-by-step explanation:
The question is not well writen
Assume p = t+5/t-2
We are to make t the subject of the formula
Cross multiply
p(t-2) = t+5
pt - 2p = t+5
pt - t = 2p+5
t(p-1) = 2p+5
t= 2p+5/p-1
Hence the value of t is 2p+5/p-1
Determine how many people will fit in a building with a width of 105 feet and a length of 250 feet, if we use a standard of 16 people per 25 square feet.
Answer:
16,800 people
Step-by-step explanation:
105 * 250 = 26,250
p = 26250ft² * (16 people / 25ft²)
p = 16,800 people
Answer:
16800
Step-by-step explanation:
105 x 250 = 26250 and then divide it by 25 which is 1050 then multiply by 16 which is 16800

Find the slope on the line?
Answer:
slope=0
Step-by-step explanation:
Hi there!
We're given a graph with a line and two marked points on the graph: (-1,3) and (3,3)
the formula given for slope calculated from two points is (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are points
we have our two points: (-1,3) and (3,3) and we can label them:
x1=-1
y1=3
x2=3
y2=3
now substitute into the formula
note: Remember the formula shows SUBTRACTION, even though we have NEGATIVE numbers. When we simplify, we'll add the numbers.
slope=(3-3)/(3--1)
simplify
slope=0/4
divide
slope=0
Hope this helps!
How does the distance traveled and time elapsed compare for Carrie and Kevin as they traveled from mile marker 225 to mile marker 230?
Answer:
This implies that they traveled the same distance and they spend the same amount of time from 225 to 230 mile marker
Step-by-step explanation:
Given
See attachment for graph
Required
Compare the distance and time travel
From the attached graph, we have the origin to be (0,0).
This represents the mile marker 225
Mile marker 230 is represented by point 5 on the y-axis.
Kevin's line at point 5 is represented as: (16,5)
Carrie's curve at point 5 is represented as: (16,5)
Both points are equal; i.e.
[tex](16,5) =(16,5)[/tex]
This implies that they traveled the same distance and they spend the same amount of time from 225 to 230 mile marker
−10x 2 +70x
factor the expression completely
Answer:
[tex]-10x^2 + 70 x = 10x(-x + 7)[/tex]
Explanation :
[tex]-10x^2 + 70x = -10\cdot x\cdot x + 7 \cdot 10 \cdot x[/tex]
'x' and '10' are common in the first and second term. so we take them outside the parenthesis and write the remaining terms inside.
That is, 10 x (-x + 7)

Answer:
Length of Line AC = 26 units
Step-by-step explanation:
Given:
Line AC = [3x + 1] + 8
Line BC = [x - 2] + 2
Find:
Length of Line AC
Computation:
Line AB ║ Line L
So,
Using Mid-Point theorem;
[3x + 1] / 8 = [x - 2] / 2
2[3x + 1] = 8[x - 2]
6x + 2 = 8x - 16
8x - 6x = 16 + 2
2x = 18
x = 9
So,
Line AC = [3x + 1] + 8
Line AC = [3(9) + 1] + 8
Line AC = [27 + 1] + 8
Line AC = 28 + 8
Length of Line AC = 26 units

A die is rolled 2 times. What is the probability of getting a 2 on the first roll and a 5 on the second roll?
Answer:
1/36
Step-by-step explanation:
the chance of rolling a 2 on a 6-sided die is 1/6 and rolling a 5 on a 6-sided is also 1/6.
So, 1/6 * 1/6 = 1/36
Hope this is helpful
Answer:
Step-by-step explanation:
six sided die gives you 6 possibilities
probability of rolling a 2 is 1/6
probability of rolling a 5 on the second roll is 1/6
Order from least to greatest
1/8, 11/12, 9/8
Answer:
Step-by-step explanation:
First make the denominators the same.
Take the LCM of (8, 12 , 8) = 24
So,
[tex]\frac{1}{8}, \frac{11}{12}, \frac{9}{8} \ becomes \ \frac{3}{24}, \frac{22}{24}, \frac{27}{24}[/tex]
[tex]Order \ from \ least \ to \ greatest \ \\\\\frac{3}{24} < \frac{22}{24} < \frac{27}{24}[/tex]
That is,

Use the volume formula to find the volume of the prism.
A. 9 cubic units O
B. 18 cubic units
C. 4 cubic units O
D. 7 cubic units
9514 1404 393
Answer:
A. 9 cubic units
Step-by-step explanation:
We interpret the smudges in your attachment to be dimensions of 1 1/2, 4, and 1 1/2. The volume is the product of these.
V = LWH
V = (4)(1.5)(1.5) = 9 . . . . cubic units
The volume of the prism is 9 cubic units.

The spread of a rumor in a town can be modeled as , where N is the number of people who have heard of the rumor, and t is time (in days). How long will it take until 2000 people know about the rumor?
Answer:
the time is 16 days
Step-by-step explanation:
The computation of the time period is given below:
N = 500 √t
2000 = 500 √t
√t = 4
Now do the square on both the sides
SO,
t = 16
Hence, the time is 16 days
We simply applied the above method to determine the time period

Combine any like terms in the expression. If there are no like terms, rewrite the expression.
5t+t–2t
Answer:
4t
Step-by-step explanation:
Note that teach term has the variable t in it. Also, note that if t is by itself, it actually means 1t. Combine the given constants:
5t + 1t - 2t
= (5t + 1t) - 2t
= (6t) - 2t
= 4t
4t is your answer.

If the above cube is a container with an inside length of 25cm, how many
3.3.3
litres will it hold?
Answer:
Capacity of cube in liter = 15.625 liter
Step-by-step explanation:
Given:
Side of cube = 25 cm
Find:
Capacity of cube in liter
Computation:
Volume of cube = Side³
Volume of cube = 25³
Volume of cube = 15,625 cm³
We know that
1 cm³ = 0.001 liter
Capacity of cube in liter = Volume of cube in cubic cm x 0.001
So,
Capacity of cube in liter = 15,625 x 0.001
Capacity of cube in liter = 15.625 liter
