Answer:
Equal sides of triangle = 14 cm
Base of an isosceles triangle = 47 cm
Step-by-step explanation:
Given:
Perimeter of the triangle = 75 cm
Base of an isosceles triangle = five more than three times the equal side
Find:
Lengths of isosceles triangle
Computation:
Assume;
Equal sides of triangle = a
So,
Base of an isosceles triangle = 3a + 5
Perimeter of the triangle = Base of an isosceles triangle + 2[Equal sides of triangle]
Perimeter of the triangle = 3a + 5 + 2[a]
Perimeter of the triangle = 5a + 5
75 = 5a + 5
5a = 70
a = 14
Equal sides of triangle = 14 cm
Base of an isosceles triangle = 3a + 5
Base of an isosceles triangle = 3(14) + 5
Base of an isosceles triangle = 42 + 5
Base of an isosceles triangle = 47 cm

In a football game, one team makes 5 plays. The result of those plays are: gain of 7 yards, gain of 2 yards, loss of 5 yards, loss of 23 yards, gain of 16 yards. What is the overall gain or loss of all 5 plays?
Answer: Loss of 3 yards
Step-by-step explanation:
The overall gain or loss of all 5 plays will be gotten by adding all the results of the plays given and this will be:
= 7 + 2 - 5 - 23 + 16
Collect like terms
= 7+2+16-5-23
= 25 - 28
= -3
The overall loss of all 5 plays will be -3 yards or loss of 3 yards

7.92 + 5.37 using rounding to estimate
Rounding decimals is like rounding whole numbers. 7.92 is closer to 8 right?. Because if you take out the decimal point it would be 792. And you rounded that to 800 now put the decimal point back which is 8.00= 8. do the same thing to 5.37 and you get 5. 8+5= 13 and that is your answer. Hope this helped
The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :
1. A light year is defined as the distance light travels in one year. A galaxy is about 150,000 light years wide. About how many kilometers wide is a galaxy if 1 light year is given below? * 9.46x10^{12}
Answer: 1.419 * 10¹⁸ km
Step-by-step explanation:
The galaxy in question is 150,000 light years wide.
If 1 km = 9.46 * 10¹² then the width of this galaxy in kilometers is:
= Distance in light years * Conversion factor of light years to kilometers
= 150,000 * 9.46 * 10¹²
= 1,419,000 * 10¹² km
= 1.419 * 10¹⁸ km

Explain how to find the quotient of 1/4 divided by 5
Answer:
1/20
Step-by-step explanation:
(1/4) / 5
When dividing a fraction by a whole number
multiply the divisor by the number
4 * 5 = 20
(1/4) / 5 = 1/20
Answer:
Convert 1/4 to decimal form, which is 0.25.Divide 0.25 by 5 The quotient is 0.05, or 1/20 in simplified fraction formThere is another way to solve without converting:
Set up equation like this: 1/4 x 1/5 (Use KCF if you know how to divide or multiply by fractions. If you don't, use the first method above)1/4 x 1/5 = 1/20The quotient is 1/20Step-by-step explanation:

A track is 400 yards around how many full laps does tyler need to run if he wants to run atleast 2 milies
Answer:
17.6 laps
Step-by-step explanation:
Total distance to be covered = 2 miles
distance coved in each lap = 400 yards
We know that 1 mile = 1760 yards
therefore, 4 miles will make = 4×1760
= 7040 yards.
Number of laps to be taken
= Total distance to be covered ÷ distance coved in each lap
= 7040/400 = 17.6 laps
Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.
Solve these simultaneous equations. Use any method you want
2x+y=22
X-y=5
Answer:
by using substuton method
2x=22-y
x=22-y/2 equation (i)
so substuting the value x in x-y=5
22-y/2-y=5
22-y-2y/2=5
22-3y=10
22-10/3=y
12/3=y
4=y
now substitute the value of y in equation (i)
x=22-y/2
=22-4/2
=18/2
=9
therefore ,the value of x is 9 and y is 4
