Answer:
b = 4.5 m
Step-by-step explanation:
Since we have 2 sides of the shape and the total volume, we can easily find the measurement of the third side which is the breadth by:
volume = 160.875
v = l×h×b
160.875m=(6.5m)×(5.5m)×b
160.875m=35.75b
b = 4.5 m
Answer:
4.5m
Step-by-step explanation:
v=lbh
b=v/lh
= 160.875/(6.5×5.5)
=160.875/35.75
=4.5m

Michael read 14 books in 26 months. At the same rate, about how many books can he read in 48 months?
Answer:
336/13 books in 48 months
Step-by-step explanation:
14 books : 26 months
first, find how many books he reads in one month (by dividing the given rate by the number of months)
14 books : 26 months
/26 /26
7/13 books : 1 month
now multiply by the number of months that this problem requires
7/13 books : 1 month
*48 *48

Answer:
x = 12 and y = 24 Can I get brainiiest
Step-by-step explanation:
We know (3x + 34) and (2x + 46) are vertical to each other so they equal the same measure. We will solve it like this.
3x + 34 = 2x + 46 (subtract 34 on each side)
3x = 2x + 12 (subtract 2x on both sides)
x = 12
Now plug in
3(12) + 34 = 2(12) + 46
36 + 34 = 24 + 46
70 = 70
Now all you have to do is do the other pair of angle
4y + 14 + 70 = 180 (we are using what we already know about 70)
(collect like terms)
4y + 84 = 180 (subtract 84 on both sides)
4y = 76 (divide by 4)
y = 24
(plug in)
4(24) + 14 = 6(24) - 34
96 + 14 = 144 - 34
110 = 110

It was -8°F in the morning. The temperature increased throughout the day, and in the afternoon, it was 11°F. How much did the temperature change?
Answer:
19
Step-by-step explanation
This is simple
I will teach you a simple technique
Count them, don't count the -8
-8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
You are just subtracting, but instead counting.
I said not to count -8, because normally in subtraction, we normally don't count the number we are subracting.
for example
8 - 7 = 1
so counting technique
8 - 7, 6, 5, 4, 3, 2, 1
there are 7 numbers, if i didn't count the 8
so it is right.

Answer:
A and C
Step-by-step explanation:
When you are dividing exponents you subtract. So for this problem -8 - -4 = -8 + 4 = -4. This means that the new exponent would be -4.
When you have a negative exponent, the equation is a fraction. As an example x^-5 would be equal to 1/x^5. For this equation, since you know that the new exponent is -4, an equivalent equation would be 1/3^4.
Hope this helps
Jim is investing in the stock market. Jim is hoping to earn $2,000 in interest in order to take a trip to Mexico. Stock A earns 4% interest and Stock B earns 7% interest, and Jim has a total of $32,000 to invest. How much should he invest in each in order to earn $2,000 interest?
Given:
Total amount for investment = $32000
Rate of interest for Stock A = 4%
Rate of interest for Stock B = 7%
Jim is hoping to earn $2,000 in interest.
To find:
The amount of investments in Stock A and Stock B.
Step-by-step explanation:
Let amount of investments in Stock A = $x
Amount of investments in Stock B = $y
Total amount for investment = $32000
[tex]x+y=32000[/tex] ...(i)
Rate of interests in Stock A and Stock B are 4% and 7%. Total interests is $2000.
[tex]0.04x+0.07y=2000[/tex] ...(ii)
From (i) and (ii), we get
[tex]0.04x+0.07(32000-x)=2000[/tex]
[tex]0.04x+2240-0.07x=2000[/tex]
[tex]-0.03x=2000-2240[/tex]
[tex]-0.03x=-240[/tex]
Divide both sides by -0.03.
[tex]x=\dfrac{-240}{-0.03}[/tex]
[tex]x=8000[/tex]
Put x=8000 in (i).
[tex]8000+y=32000[/tex]
[tex]y=32000-8000[/tex]
[tex]y=24000[/tex]
Therefore, the amount of investments in Stock A and Stock B are $8000 and $24000 respectively.
Select all the equations where b=11b=11b, equals, 11 is a solution. Choose 2 answers: Choose 2 answers: (Choice A) A 2b=2112b=2112, b, equals, 211 (Choice B) B b+18=7b+18=7b, plus, 18, equals, 7 (Choice C) C 77=7b77=7b77, equals, 7, b (Choice D) D 9=b-29=b−29, equals, b, minus, 2 (Choice E) E 11=33\div{b}11=33÷b
Answer:
Step-by-step explanation:
We are to choose all the equation that evaluates b to be 11. The following equations are true;
77 = 7b
To get b, we will divide both sides by 7
77/7 = 7b/7
11 = b
b = 11
This shows that the equation is correct since b = 11
Also 9 = b-2
To get b, we will add 2 to both sides of the expression
9+2 = b-2+2
11 = b
b = 11
This shows that the equation is correct since b = 11
Hence option C and D are correct

Write an interpretation of the statement f(3) = 75.
Given:
The statement is
[tex]f(3)=75[/tex]
To find:
The interpretation for the given statement.
Solution:
We know that,
[tex]f(x)=y[/tex] ...(i)
Here, x is the input value and y is the output value.
We have,
[tex]f(3)=75[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]x=3,y=75[/tex]
It means, the output value of the function f(x) is 75 at x=3.
true or false, the ratios 4:10 and 8:20 are equivalent
PLEASE HELP IF I FAIL MY MOM IS GONNA-
Answer:
True
Step-by-step explanation:
If you multiply both 4 and 10 by two, you get 8 and 20
The ratios 4:10 and 8:20 are Equivalent.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
As, when the two ratios are equal after simplifying then they are equivalent ratio.
So, 4/10
= 2/5
and, 8/20
= 2/5
As, both ratios are giving equal value after simplifying.

Identify the most precise name for the angle pair shown in the picture.
1. Adjacent Angles
2. Supplementary Angles
3. Vertical Angles
4. Linear Pair
5. Complementary Angles
Answer:
Complementary Angles
Step-by-step explanation:
Complementary angles are angles whos measures add up to 90 degrees! The angles in the picture can also be described as adjacent angles, because they share the same vertex.
So these angles are technically both complementary and adjacent, but they are more specifically, complementary.

(e) If f(x+3) = f(x) + f(5) then prove that: f(2)= 0 and f(5) = -f(-1)
Answer:
See below.
Step-by-step explanation:
f(x + 3) = f(x) + f(5) (Given) so:
f(2 + 3) = f(2) + f(5)
and f(2) = f(2 + 3) - f(5)
= f(5) - f(5) = 0.
f(-1) = f(-1 +3) - f(5)
= f(2) - f(5)
= f(-3)
So - f(-1) = f(3)
Also:
f(5) = f(x + 3) - f(x)
= f(x + 3 - x)
= f(3).
But f(3) = -f(-1) ( shown above),
So f(5) = -f(-1).
