Find The Measure Of Angle A.can You Show Me How To Do This Problem

Answers

Answer 1

Answer:

x = 25/2

Step-by-step explanation:

We may apply the property of triangles that says the three angles must add up to 180 degrees.  Therefore:

x + 4 + x + 61 + 90 = 180

2x + 65 = 90, or

2x = 25, and so x = 25/2

Lincoln estimates the height of a tree. Lincoln's estimate has a 6% error.
The actual height of the tree is 17 feet. What could be Lincoln's estimate?
Choose all the correct answers.
A 11
B 15.98
C 18.02
D 16.94
E 23

Answers

Answer: B, C and D

Explained:

17 * .06 = 1.02

So 15.98 - 18.02 are all within Lincoln’s estimate and error rate.

B, C and D are all within the 6% error rate. So the answers are B, C and D.

An initial population of 415

ducks increases at an annual

rate of 32%. Write an

exponential function to model

the duck population.

Answers

Answer:

The exponential function to model the duck population is:

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years

Step-by-step explanation:

In order to calculate the duck population you can use the formula to calculate future value:

FV=PV*(1+r)^n

FV=future value

PV=present value

r=rate

n=number of periods of time

In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:

f(n)=415*(1+0.32)^n

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years

Uh whats the area of the figure??????

Answers

Answer:

42.5

Step-by-step explanation:

The figure shown is a trapezoid

The area of a trapezoid can be calculated using this formula

[tex]A=\frac{a+b}{2} h[/tex]

where a and b = bases and h = height

The trapezoid has the following dimensions

base 1 = 7 m

base 2 = 10 m

height = 5 m

Given this information we plug in the values into the formula

[tex]A =\frac{7+10}{2} 5\\7+10=17\\\frac{17}{2} =8.5\\8.5*5=42.5 \\A=42.5[/tex]

So we can conclude that the area of the trapezoid is 42.5 square units

Sam has 24 quarters, 18 nickels, and 36 dimes. He wants to divide the coins into groups so that each group is worth the same amount of money. What is the greatest number of groups Sam can make using all the coins?

HURRY PLEASE

Convert this monies to dollar

Quarters - 24 x 0.25 = $6  

Nickels = 18 x 0.05 = $0.9

Dimes = 36 x 0.1 = $3.6

sum of these amounts = $10.50

the greatest group is 5 and each group would be worth $2.10

A) 3 hours
B) 40 hours
C) 20 hours
D) 10 hours

Answers

Answer:

A) 3 hours

Step-by-step explanation:

x = per hour

y = total

Dana:

y = 10x + 10

Tommy:

y = 9x + 13

Combined (Solve for x):

y = 10x + 10

y = 9x + 13 (Multiply by -1)

y = 10x + 10

-y = -9x - 13

0 = x - 3

x = 3

6 The interior angles of a triangle always sum to 180°. The measure of ZC is 8°
less than the measure of ZD. Find the values of x and y.

Answers

Answer:

m<D=67

m<C=59

Step-by-step explanation:

m<C=y-8

m<D=y

m<A=54

put all the angles together and equal to 180

(y-8)+(y)+(54)=180

now solve the equation

67=y

(67)-8=59
