May someone help me with this question it says: Sam's tent has slanted sides that each 5 feet long with the bottom 6 feet across. What is the height of his tent at it's tallest point? A.3.0ft B.3.5ft C.4.0ft D.5.0ft
Answer:
C) 4.0 ft
Step-by-step explanation:
We will use the Pythagorean theorem to solve this. It states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse; algebraically,
a²+b² = c²
The height splits the base in two, giving us a leg of 3. The hypotenuse is 5. This gives us:
3²+b² = 5²
9+b² = 25
Subtract 9 from each side:
9+b²-9 = 25-9
b² = 16
Take the square root of each side:
√b² = √16 = 4
how do i solve 13 + a/11 = 7

Step 1: Define
13 + a/11 = 7
Step 2: Solve for a
Subtract 13 on both sides: a/11 = -6Multiply 11 on both sides: a = -66Step 3: Check
Plug in a into the original equation to verify it's a solution.
Substitute in a: 13 - 66/11 = 7Divide: 13 - 6 = 7Subtract: 7 = 7Here we see that 7 does indeed equal 7.
∴ a = -66 is the solution to the equation.
Answer:
If you mean [tex]\frac{13+a}{7}=7[/tex] then the answer is [tex]a=36[/tex].
If you mean [tex]13+\frac{a}{7} =7[/tex] then the answer is [tex]a=-42[/tex].
Step-by-step explanation:
To do this question, you simplify both sides of the equation and then isolate the variable.

The greatest common factor of two numbers is 4. The sum of the numbers is 76. What are the two numbers? A. 38 and 38 B. 12 and 64 C. 18 and 58 D. 32 and 40
Answer: B. 12 and 64
Step-by-step explanation:
Option A is incorrect because the highest common factor for both numbers would be 38 not 4.
Option B:
Factors of 12 are: 1, 2 , 3, 4, 6, 12
Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.
Highest factor of both is 4 and they both add up to 76 so option B must be correct.
Answer:
12 and 64 !

Answer: hi want to be fwends
Step-by-step explanation:
There can 3 songs to be played for per quarter.
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement.
Given that, It cost Sean 3.75 to play 45 songs on an old jukebox. The jukebox only accepts quarters.
Converting $3.75 into quarters, ($1 = 4 quarters)
$3.75 = 3+0.75
= 3x4+0.75
= 12+3
= 15 quarters
So, he played 45 songs in 15 quarters
Therefore, in 1 quarters = 45/15
= 3
Hence, There can 3 songs to be played for per quarter.

Malcolm Little High School has sopho- mores, juniors, and seniors, but no freshmen. The ratio of sophomores to juniors is 5 to 4, and the ratio of juniors to seniors is 3 to 2. If there are 300 sophomores, how many seniors are there?
Answer:
161 seniors
Step-by-step explanation:
According to the problem, given data are as follows:
Total number of sophomores = 300
Sophomores to junior ratio = 5:4
So, Number of Juniors = 300 × (4 ÷ 5)
= 240
Now, Juniors to senior ratio = 3:2
So, we can calculate the number of seniors by using following method:
Number of seniors = 240 × ( 2 ÷ 3)
= 240 × 0.67
= 160.8 or 161

The following is an equilateral triangle. Solve for y.
(y-8)°
A) 57 Degrees
B) 60 Degrees
C) 68 Degrees
D) 72 Degrees
Answer:
y = 68 degrees
Step-by-step explanation:
Here, we want to solve for an equilateral triangle with the internal angle measurement being y-8
If one of the angles is y-8, then the rest are y-8 too
mathematically, by adding all , we have a total of 180
Thus;
3(y-8) = 180
y-8 = 180/3
y-8 = 60
y = 60+8
y = 68 degrees

Ella was paid an 11 percent commission on the pair of shoes that she sold. The department store had paid $25 wholesale for the shoes and had marked up the price by 40 percent to the selling price. How much did Ella earn for the sale?
Answer:
The answer is B. $3.85.
Step-by-step explanation:
This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.
Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.
This is why the answer is B. $3.85.

Lins father is paying $20 for a meal. He has 15%-off coupon for the meal. After the discount, 7% sales tax is applied, How much does Lins father pay for the meal?
Answer: $18.19
Step-by-step explanation:
The tax is applied after the discount so first find the discounted price:
= Price * ( 1 - discount rate)
= 20 * ( 1 - 15%)
= $17
The sales tax of 7% can then be applied:
= Price * ( 1 + tax rate)
= 17 * ( 1 + 7%)
= $18.19

The mean temperature for the first 7 days in January was 5 °C. The temperature on the 8th day was 8 °C. What is the mean temperature for the first 8 days in January
Answer:
The mean temperature for the first 8 days in January is 5.375 °C
Step-by-step explanation:
The means = The sum ÷ The number
∵ The mean temperature for the first 7 days in January was 5 °C
∴ The mean = 5
∴ The number = 7
→ Substitute them in the rule above
∵ 5 = The sum ÷ 7
→ Multiply both sides by 7
∴ 35 = The sum
∴ The sum of the temperature for the first 7 days is 35 °C
∵ The temperature on the 8th day was 8 °C
→ Add it to the sum of the first 7 days to find the sum of the first 8 days
∴ The sum of the first 8 days = 35 + 8
∴ The sum of the first 8 days = 43 °C
∵ The number of days = 8
→ Substitute them in the rule above to find the mean
∴ The mean = 43 ÷ 8
∴ The mean = 5.375 °C
∴ The mean temperature for the first 8 days in January is 5.375 °C

Answer:
30 sweets
Step-by-step explanation:
From the above question
The ratio is given as:
Karan : Preeti
2:3
The sum of the proportion = 2 + 3 = 5
Total number of sweets = 50 sweets
The number of sweets Preeti will get is calculated as:
3/5 × 50 sweets
= 30 Sweets
Therefore, the number of sweets Preeti will get is 30 sweets
F is inversely proportional to d squared. When F = 16 , d = 3 Work out d (positive value rounded to 2 DP) when F = 8
Answer:
d = 3√2
Step-by-step explanation:
find the constant of variation ('k'): F = k/d²
16 = k/3²
16 = k/9
k = 144
8 = 144/d²
d² = 144/8
d² = 18
d = √9 · √2
d = 3√2
Lucy and Greg each want to buy a bicycle. Lucy has already saved $35 and plans to save $10 per week. Greg has $26 and plans to save $13 per week. How many weeks will it take for Lucy and
Gregory to have the same amount of money saved? How much money will they have saved?
Answer:
3 weeks
65 dollars
Step-by-step explanation:
Alright to answer this question we have to set up an equation. For greg the equation is y=13x+26 and for lucy the equation is y=10x+35. y is total amount of money saved and x is number of weeks. Since we want them to each of the same amount of money we set up the equations to be 10x+35=13x+26
then we want to get the constant and the variables alone on different sides of the equal sign so we first subtract 26 from each side to get 10x+9=13x. next we want to subtract 10x from each side and then we end up with 3x=9. Finally we divide 3 from each side to get x=3, We have answered the question to how many week it will take them to save the same amount of money but not the other part. To find out how much money they will both have in 3 weeks we plug in 3 to x. 10(3)+35 which is equal to 65. They will both have 65 dollars in three weeks
