The sum of two positive integers is 40. When the smaller integer is subtracted from twice the larger, the result is 41. Find the two integers.
Answer:
13 and 27
Step-by-step explanation:
x+y=40
x- smaller
2y-x=41
x=2y-41
Now to plug it into our first equation:
3y-41=40
3y=81
y=27
x=13
The dimensions of a right rectangular prism are 2 m, 2.5 m, and 4.5 m.
What is the volume of the prism? Enter the answer in the box.
Answer:
volume= length ×width×height
2×2.5×4.5
22.5
The volume of a right rectangular prism with sides 2 m , 2.5 m and 4.5 m will be 22.5 m³.
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
All the sides of a rectangle are;
2 m , 2.5 m and 4.5 m
Now,
Since, we know that;
Volume of rectangle = Length x Width x Height
Substitute all the values we get;
Volume of right rectangular prism = 2 x 2.5 x 4.5
= 22.5 m³
Thus, The volume of a right rectangular prism with sides 2 m , 2.5 m and 4.5 m will be 22.5 m³.

I DESPERATELY NEED YOUR HELP!! A cat gets stuck on the roof. If the latter is 12 feet long and must be placed 7 feet away from the building. How high can the ladder reach up the building to save the cat
Answer:
84
Step-by-step explanation:
Answer:
your answer is 9.7 feet
Step-by-step explanation:
you apply Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex] since you are looking for height you can subsitute x for a or b and since 12 is the largest number this will be your c which is your hypotneuse and 7 will be subsituted as a or b depending on what letter you used as your x value [tex]7^{2} +b^{2} =`12^{2}[/tex] is equal too 49 +b^2 =144 you then subtract 49 on both sides to isolate your x (b) and this gets you 95 and then you find the square root of 95 which is 9.7

when x increases from a to a +2, y increases by a factor of 1/4
Answer:
y=7* (0.5)^x
Step-by-step explanation:
We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.
i.e. when x=a and x'=a+2.
then y/y=0.25 where y' is the function after putting x' to the old function.

1. Understand that a triangle always has the additive degrees of 180.
2. Use x+55+40=180, to isolate x, subtract 55 and 40 from 180.
3. You get x = 85.
Answer:
B. 85 degrees
Step-by-step explanation:
According to the Triangle Sum Theorem, all the angles inside a triangle equal 180 degrees. The work is below:

Triangle ABC is the pre-image and Triangle ADE is the image. What transformation took place?
a. Reflection
b. Translation
c. Dilation
d. Rotation
Answer:
translation...........
Answer:
Dilation
Step-by-step explanation:
A dilation is a type of transformation that changes the size of the image. The scale factor measures how much larger or smaller the image is.
In this example, ΔABC is dilated as seen in the picture because it the picture itself got bigger.
The image, ΔADE is now a dilated version of the pre-image ΔABC

Solve the given equation for x. 8−65x=10
Answer:
Exact form is [tex]x=-\frac{2}{65}[/tex]
And the decimal form is x = −0.0307692
Answer:
The value of x is -2/65
Step-by-step explanation:
The given equation is
8 - 65x = 10
We are asked to find the value of x.
Step 1: Subtract 8 from both sides
-8 + 8 - 65x = 10 - 8
-65x = 2
Step 2: Divide both sides by -65
-65x/-65 = 2/-65
x = -2/65
Therefore, the value of x is -2/65

Giving brainliest to whoever helps me.
Answer:
w = 2.5 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 5 and h = 6, thus
A = 0.5 × 5 × 6 = 15 cm²
Thus the area of the rectangle is 15 cm²
A = lw ( l is the length and w the width )
Here l = 6 and w is to be found
6w = 15 ( divide both sides by 6 )
w = 2.5 cm

Answer:
4a ) Difference ⇒ $ 63.24,
4b ) 4 children
Step-by-step explanation:
4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;
y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,
y = 42.16 + 85.15 ⇒ Combine like terms,
y = 127.31
If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;
y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,
y = 105.4 + 85.15 ⇒ Combine like terms,
y = 190.55
Difference; 190.55 - 127.31 = 63.24,
Solution; Difference ⇒ $ 63.24
4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;
169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,
21.08x = 84.32 ⇒ Divide either side 21.08,
x = 4 children
Solution; 4 children

The sum of two consecutive integers is 77. Find the integers.
Answer:
38 and 39
Step-by-step explanation:
Since the two integers are consecutive, then one is one larger than the other. Therefore, lets call them x and x+1. We can now set up the following equation:
x+(x+1)=77
2x+1=77
2x=76
x=38
x+1=39
Hope this helps!
Answer:I believe it is 39 and 38
Step-by-step explanation:
x + (x+1) = 77
2x = 76
x = 38 (1st number)
x+1 = 39 (2nd number)
A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 70% salt and Solution B is 95% salt. She wants to obtain 50 ounces of a mixture that is 80% salt. How many ounces of each solution should she use?
Answer:
30 ounces of solution A
20 ounces of solution B
Step-by-step explanation:
x ounces of solution A
y ounces of solution B
x + y = 50
0.7x ounces of salt in the solution A
0.95y ounces of salt in the solution B
0.8*50 = 40 ounces of salt in 50 ounces of 80% solution
0.7x + 0.95y = 40
x + y = 50
0.7x + 0.95y = 40
x= 50 - y
0.7(50 - y) + 0.95y = 40
35 - 0.7y + 0.95y = 40
0.25y = 5
y = 20 ounces of solution B
x = 50 - y = 50 - 20 = 30 ounces of solution A
For acute triangle XYZ below, can you find the tangent ratio of angle r°?
Answer:
Tan r = z/y
Step-by-step explanation:
Tangent = opposite / adjacent
Line XY, which is z, is opposite of angle r.
Line XZ, which is y, is adjacent to angle r.
The equation would be Tan r = z/y.
Answer: No, you can't find the tangent ratio of angle rº because the tangent ratio applies to any right triangle, and it applies to right triangles ONLY.

Find the 4th term of the expansion of (a - sqrt(2)) ^ 8
Answer:
Applying the binomial theorem
[tex]{\displaystyle (x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}}[/tex]
Here we have x = -[tex]\sqrt{2}[/tex], n = 8,
=> 4th term (k = 3) would be:
[tex]{8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}[/tex]
