Answer:
Tessa ran 39,000 meters in all
Step-by-step explanation:
if she ran 13 km a day, she ran 39 km in 3 days. To convert km to meters, you have to multiple the number by 1,000. 39 x 1,000 = 39,000 meters.
Use the Pythagorean Theorem to find l. 1 l l = 7 [?] ft 13 ft 1 2 ft a C с Pythagorean Theorem: a2 + b2 = c2 b Enter
Answer:
l = √10 ft
Step-by-step explanation:
Using Pythagorean Theorem, a² + b² = c², where,
a = ½(2) = 1 ft
b = 3 ft
c = l
Plug in the values
1² + 3² = l²
1 + 9 = l²
10 = l²
√10 = l
l = √10 ft

Which expression can be used to find the surface area of the following square pyramid?
answer: a a maybe right i guess
A+5 expressed as a difference
Answer:
A-(-5) = A+5
it is the answer
Answer:
a-(-5)
Step-by-step explanation:
Since it's originally an addition question but you want to write it as a difference (subtraction) question, you would use double negative signs. Whenever there are two double negatives next to each other, it counteracts and becomes a positive sign, however you still wrote it as a subtraction question.
Hope this helps
On a map, 1 inch equals 10 miles. Two cities are 8 inches apart on the map. What is the actual distance between the cities? The actual distance between the cities is miles.
Answer:
the actual distance between the cities is 80 miles
Step-by-step explanation:
The computation of the actual distance between the cities is shown below:
As we know that
1 inch = 10 miles
So for 8 inches it would required 80 miles
i.e.
= 8 × 10
= 80 miles
Hence, the actual distance between the cities is 80 miles

Find the value of X
Answer:
80Step-by-step explanation:
This quadrilateral is a kite
And the kite as its opposite angles equal
So based on this we can solve for x
[tex]100 + 100 + x + x = 360[/tex]
(360 here is the total sum of interior angke in a quadrilateral)
[tex]200 + 2x = 360 \\ 2x = 360 - 200 \\ 2x = 160 \\ x = \frac{160}{2} \\ x = 80[/tex]
Thisbis your answer hope it helps :))

Dominica $2000 for 3years at an interest rate of 7% how much interest did she earn on her money?
Answer:
$420
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the annual interest rate expressed as a decimal fraction, and t is the number of years.
Here p = $2,000, r = 0.07 and t = 3 yr, and so
i = ($2,000)(0.07)(3) = $420 was the amount of interest earned.

Dwayne purchased a computer from Techtronic's, Inc. for $2,600 in 2007. The rate of
depreciation is 7%. Which would be the best estimate for the value of the computer in
2010?
Answer:
[tex]\$2091.3[/tex]
Step-by-step explanation:
Let P denotes initial value of the product, r% is the annual depreciation rate and t denotes time period.
Depreciation (d) = [tex]P(1-\frac{r}{100})^t[/tex]
Put [tex]P=\$2,600,\,r\%=7\%,\,t=3[/tex] years
Therefore,
[tex]d=P(1-\frac{r}{100})^t\\\\=2600(1-\frac{7}{100})^3 \\\\=2600(\frac{93}{100})^3\\\\=\$2091.3[/tex]

Pancake Palace puts a pint of maple syrup on each one of their 16 tables. The owner is filling the syrup bottles before the restaurant opens. If the bottles are half full, how many quarts would he need to fill the bottles?
Answer:
64 quarts of maple syrup needed
Step-by-step explanation:
There are a total of 2 quarts in a 1 pint. Therefore, since there are a total of 16 tables and each one has 1 pint, then there are a total of 16 pints in the restaurant. If we multiply this by 2 we get the total amount of quarts of maple syrup in all of the tables
16 * 2 = 32 quarts of maple syrup
Since the bottles are only half full we need to multiply this amount by 2 in order to get the total syrup needed to have all of the bottles filled completely.
32 * 2 = 64 quarts of maple syrup needed
Answer:
4 Quarts
Step-by-step explanation:
You need to find how much maple syrup the owner needs to fill the bottles. But first, you need to find how much syrup the bottles hold in all.
There are 16 bottles. Each bottle holds 1 pint of maple syrup. So, the bottles hold a total of 16 pints of syrup.
Now, find how much maple syrup the owner needs. The bottles hold a total of 16 pints of syrup. Because they are half full, divide by 2.
16÷2=8
The owner needs 8 pints of maple syrup, but the problem asks about quarts. So, find how many quarts are equal to 8 pints. There are 2 pints in a quart, so divide by 2.
8÷2=4
The owner needs 4 quarts of maple syrup to fill the bottles.

Quadrilateral ABCD is a parallelogram with < BCA= 50 , < DCA=60, find value of
Answer:
[tex]ADC = 70[/tex]
Step-by-step explanation:
Given
[tex]BCA = 50[/tex]
[tex]DCA = 60[/tex]
See attachment for parallelogram and complete question
Required
Find ADC
From the attachment:
[tex]BCD = BCA + DCA[/tex]
[tex]BCD = 50+60[/tex]
[tex]BCD = 110[/tex]
Adjacent angles add up to 180.
So:
[tex]ADC + BCD = 180[/tex]
[tex]ADC = 180-BCD[/tex]
[tex]ADC = 180-110[/tex]
[tex]ADC = 70[/tex]
