Need help to solve this question- The highlighted one is incorrect
Answer:
16 might be correct but don't quote me on this...
Step-by-step explanation:
104-88=16
let me know if this is correct, Thanks! :-)
Answer:
C
Step-by-step explanation:
We can use the Pythagorean theorem [ a² + b² = c² ] to solve for the missing side length.
88² + b² = 104²
7744 + b² = 10816
b² = 3072
√b = √3072
b ≈ 55.43

Explain how to use properties to prove d + (8d + 1) + 7 is equivalent to 8 + 9d.
Answer: See explanation
Step-by-step explanation:
From the question, we are told to prove that prove d + (8d + 1) + 7 is equivalent to 8 + 9d.
= d + (8d + 1) + 7
First we need to open the bracket. This will be:
= d + (8d + 1) + 7
= d + 8d + 1 + 7
Collect like terms
= 9d + 8
= 8 + 9d
Therefore, we have proven that + (8d + 1) + 7 is equivalent to 8 + 9d.

Will weighs three times as much as Brenda. Together, they weigh 240
pounds. How much does each of them weigh
let
brenda: b
will: 3b
b + 3b = 240
4b = 240
b = 60 lbs (BRENDA)
3b = will
3 (60) = will
180 = WILL
The solution is
The weight of Brenda = 60 pounds
The weight of Will = 180 pounds
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the weight of Brenda be = x
Let the weight of Will be = y
Now , Will weighs three times as much as Brenda
Substituting the values in the equation , we get
y = 3x be equation (1)
And , the weight of Will + weight of Brenda = 240 pounds
So , x + y = 240 be equation (2)
Substituting the value of y from equation (1) in equation (2) , we get
x + 3x = 240
On simplifying the equation , we get
4x = 240
Divide by 4 on both sides of the equation , we get
x = 60 pounds
So , the weight of Brenda is 60 pounds
Substitute the value of x in equation (1) , we get
y = 3x
y = 3 x 60
y = 180 pounds
So , the weight of Will is 180 pounds
Hence , the weight of Brenda is 60 pounds and weight of Will is 180 pounds

Sandy has 27 roses, 9 daisies, and 45 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
Answer:
The greatest number of flowers that could be in a bouquet is 9 flowers.
Each bouquet would contain: 3 roses, 1 daise and 5 tulips
Step-by-step explanation:
Sandy has 27 roses, 9 daisies, and 45 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
We solve the above question using Greatest Common Factor method.
We find the factors of 27, 9 and 45
The greatest common factor is the highest factor common to these 3 number
Hence:
The factors of 9 are: 1, 3, 9
The factors of 27 are: 1, 3, 9, 27
The factors of 45 are: 1, 3, 5, 9, 15, 45
Then the greatest common factor is 9.
Therefore, the greatest number of flowers that could be in a bouquet is 9 flowers
Each bouquet would contain
For 27 roses = 27/9 bouquet = 3 roses
For 9 daisies = 9 daisies/9 bouquet = 1 daisies
For 45 tulips = 45 tulips/9 bouquet = 5 tulips

then multiply both sides by 4 to find b: b = -12
Answer:
b= -12
Step-by-step explanation:
b/4 + 2 = -1
Subtract 2 from both sides
b/4 = -3
Multiply both sides by 4
b= -12

First we need to multiply 14.3 and 17.1 to the second power.
14.30 × 14.30 = 204.49
17.10 × 17.10 = 292.41
Now we add our two sums.
204.49 + 292.41 = 496.90
Now we need to find the square root of 496.90, which is 22.2912539.
Rounded to the nearest DP(Decimal point), it's 22.30
A computer valued at $2500 loses 6.5% of its value every year. How much will it be worth in 4 years?
Answer:
The computer will be worth $1,850 after four years.
Step-by-step explanation:
We need to find 6.5% of $2,500.
2,500 x 0.065 = $162.50
Therefore, the computer value decreases by $162.50 each year. Since we need to know the computer value after 4 years, we also need to multiply the value of decrease by 4.
162.5 x 4 = $650
Therefore, after 4 years, the computer value will decrease by $650.
To find the whole computer value after 4 years, we need to subtract the initial value of $2,500 by the 4-year decreasing value of $650.
2,500 - 650 = $1850
Therefore, the computer will be worth $1,850 after four years.
Hope this helps! :D

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of where it was tied and 30 feet above the ground, as shown in the figure below. What is the slope of the line between the balloon and the point where it was tied?
Answer:
The slope is 0.55
Step-by-step explanation:
Right Triangles
The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.
The image below shows the geometric construction. We are required to find the slope the string forms with the ground.
It can be found by using the tangent ratio:
[tex]\displaystyle \tan\theta=\frac{y}{x}[/tex]
Substituting y=30 and x=55
[tex]\displaystyle \tan\theta=\frac{30}{55}[/tex]
[tex]\displaystyle \tan\theta=0.55[/tex]
The slope is 0.55

A circle has an area of 25pi Another circle has a diameter 5 times the first. What is the diameter of 2nd circle
Answer:
the Diameter of second circle is 50
Step-by-step explanation:
Area of first circle = 25 π
Diameter of first circle = d
Diameter of second circle= 5(Diameter of first circle) (because Another circle has a diameter 5 times the first)
We need to find diameter of 2nd circle.
First we find diameter of first circle.
The formula for area of circle is: [tex]Area=\pi r^2[/tex]
We also know that: [tex]Diameter = 2r[/tex]
First we will find radius and using diameter formula we can find diameter of the circle.
[tex]Area=\pi r^2\\25\pi =\pi r^2\\r^2=\frac{25\pi}{\pi}\\r^2=25\\Taking\:square\:root\:on\:both\:sides\\\sqrt{r^2}=\sqrt{25}\\r=5[/tex]
So, radius of first circle is r = 5
Now, finding diameter of first circle:
[tex]Diameter = 2r\\Diameter= 2(5)\\Diameter= 10[/tex]
So, Diameter of first circle = 10
Now, we know that diameter of second circle is 5 times the first
So, Diameter of second circle = 5(Diameter of first circle)
Diameter of second circle = 5(10)
Diameter of second circle = 50
So, the Diameter of second circle is 50
