Answer:
AC = 7.5 cm
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AC}{DE}[/tex] = [tex]\frac{BC}{DE}[/tex] , substitute values
[tex]\frac{AC}{3.5}[/tex] = [tex]\frac{7+8}{7}[/tex] , that is
[tex]\frac{AC}{3.5}[/tex] = [tex]\frac{15}{7}[/tex] ( cross- multiply )
7AC = 52.5 ( divide both sides by 7 )
AC = 7.5 cm
Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided. 4(3 - 2x) = 15
Answer:
x = -3/8
Step-by-step explanation:
4(3 - 2x) = 15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 =15-12
-8x =3
Divide by -8
-8x/-8 = 3/-8
x = -3/8
The correct answer is: -3/8
Write the algebra expression: six times the sum of four and a number
Answer:
6(4+x)
Step-by-step explanation:
Answer:
6(x+4)
Step-by-step explanation:
We want to write an algebraic expression for "six times the sum of four and a number"
Let's break this down.
The sum of four and a number:
The words "sum" indicates addition. We can call " a number" x, since it is unknown.
So, the sum of four and a number is: (x+4).
Six times:
The word "times indicates multiplication. We are multiplying six and the sum of four and a number.
So, we have: 6(x+4)
The algebra expression for "six times the sum of four and a number" is 6(x+4)

Answer:
9
Step-by-step explanation:
The reason why it is 9 is because if you look to the bigger triangle, you can see that 15 is 3/4 the size of 20, so once you find what number is 3/4 of 12, you have the answer, 9! Hope this helps!

what is the answer to g+3=17
Answer:
g=14
Step-by-step explanation:
do 17-3, the answer is 14, meaning 14=g
Answer:
g = 14
Step-by-step explanation:
g+3 = 17
Subtract 3 from each side
g+3-3 = 17-3
g = 14
There are 7 more sweaters than shirts in the drawer. There are 15 sweaters and shirts in the drawer in all. How many shirts are there in the drawer? Let S represent the number of shirts. Which equation represents the situation
Answer:
7 + 2s = 15
4 shirts
Step-by-step explanation:
Let's say w denotes sweaters and s denotes shirts.
Since there are 7 more sweaters than shirts:
w = 7 + s
There are a total of 15 sweaters and shirts in all, so:
w + s = 15
Substitute 7 + s in for w in the second equation:
w + s = 15
7 + s + s = 15
7 + 2s = 15
Solving for s:
7 + 2s = 15
2s = 15 - 7 = 8
s = 8/2 = 4 shirts
Thus, the equation is 7 + 2s = 15, and there are 4 shirts.

The circumference of a quarter is approximately 7.54 mm. What is its diameter to the nearest tenth of a millimeter? (π = 3.14)
Answer:
2.40mmStep-by-step explanation:
In this problem. we are required to solve for the diameter of a circle.
Given data
circumference of circle c= 7.54mm
we know that the expression for the circumference is given as
c= 2πr
We can substitute our given data to solve for r
7.54= 2*3.142*r
7.54=6.284*r
divide both sides by 6.284 we have
r= 7.54/6.284
r= 1.199
diameter = 2*r
diameter= 1.199*2
diameter= 2.399
to the nearest tenth
diameter= 2.40mm

The length of an alligator in a zoo is 14 5/6 feet.The everglades national parks list the longest alligator ever reocord in florida at 17 5/12 feet. Which is the differnce in their lenghth
Answer:
The difference in the lengths of the two alligators = 3
Step-by-step explanation:
First, let us make the lengths improper fractions, then we will find the difference from there.
Alligator 1:
Length = [tex]14\frac{5}{12} = \frac{173}{12}[/tex]
To convert to improper fraction, multiply the denominator by the whole number, and then add the denominator [(12 × 14) + 5]
Alligator 2:
Length = [tex]17\frac{5}{12} = \frac{209}{12}[/tex]
Now Let us find the difference between the lengths:
[tex]\frac{209}{12} - \frac{173}{12} = \frac{36}{12} =3[/tex]
Therefore the difference in the lengths of the two alligators = 3
9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing
through the point (5,9). Is either of them correct? Explain your reasoning?
Krista:
9 = 3(5) + b
9 = 15 + b
-6 = b
y = 3x - 6
Emily:
y- 9 = 3(x - 5)
y- 9 = 3x - 15
y = 3x - 24
Answer:
Explanation:
Step-by-step explanation:
Hey there!
The equation, of a st. line that passes through point (5,9) is,
[tex](y - y1) = m1(y - y1)[/tex]
Put the values,
[tex](y - 9) = m1(x - 5)[/tex]
It is 1st equation.
Now, another equation is,
y = 3x-1.........(ii)
Comparing the equation with y = mx+c.
Slope (m2)= 3
As per the parallel lines,
m1=m2=3
Putting,
the value of m1 in equation(i)
(y-9)= 3(x-5)
y-9= 3x - 15
y = 3x - 6.
So, Krista equation is correct.
Hope it helps...
HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Answer:
3
Step-by-step explanation:
So we have the function:
[tex]f(x)=3x^2+2x-5[/tex]
To evaluate the value of f(-2), substitute -2 for x. Thus:
[tex]f(-2)=3(-2)^2+2(-2)-5[/tex]
Square first:
[tex]f(-2)=3(4)+2(-2)-5[/tex]
Multiply:
[tex]f(-2)=12-4-5[/tex]
Now, subtract:
[tex]f(-2)=8-5=3[/tex]
So:
[tex]f(-2)=3[/tex]

What is
the circumference of a circle with radius 3.5cm. Take [Pi=22/7]
Answer:
22cm
Step-by-step explanation:
Circumference of a circle = 2πr
π = 22/7
r = 3.5
Circumference of a circle = 2 × (22/7) × 3.5
Circumference of a circle = 22cm.
Hugh bought some magizines that cost 3.95 each and some books that cost 8.95 each. He spent a total of 47.65.If Hugh bought 3 magazines,how many books did he buy
Answer:
4 books
Step-by-step explanation:
We are told that: Hugh bought some magazines that cost 3.95 each
Hugh bought 3 magazines.
Hence, total cost of magazines = 3 magazines × 3.95
= 11.85.
Total cost of magazines = 11.85
From the question, we know that, the total amount Hugh spent = 47.65
Hence, The total cost for books =
Total amount spent - Total cost of magazines
= 47.65 - 11.85
= 35.80
Therefore, the total cost of books = 35.80
We are told in the question that the cost of books is 8.95 each or 8.95 per book.
Hence, the number of books that Hugh bought is calculated as :
35.80/8.95
= 4 books
Therefore, Hugh bought 4 books

Answer:
x=5/16
Step-by-step explanation:
Let's solve your equation step-by-step.
4x(−4)=−2−(−3)−6
Step 1: Simplify both sides of the equation.
4x(−4)=−2−(−3)−6
−16x=−2+3+−6
−16x=(−2+3+−6)(Combine Like Terms)
−16x=−5
−16x=−5
Step 2: Divide both sides by -16.
−16x
−16
=−5/−16
x=5/16
