hillary is cycling across montana taking a 845 mile course . the first week she covered.320 miles. the second week she traveled another 350 miles. how many more miles does she have to travel to complete course?
Answer:
175 miles
Step-by-step explanation:
Hillary has travelled
320 + 350 = 670 miles
in the first two weeks.
Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.
670 + x = 845
And if we subtract 670 from both sides:
x = 845 - 670 = 175
175 miles
Find XZ if Y is the midpoint of XZ, XY = 2a + 11, and YZ = 4a - 5
Answer:
XZ=54
Step-by-step explanation:
X___Y___Z
XY= YZ
2a+11=4a-5
4a-2a= 11+5
2a=16
a=16/2
a=8
XY=2a+11=2(8)+11=16+11=27
YZ=4a-5 = 4(8)-5=32-5=27
XZ=XY+YZ =27+27=54

The ratio of vowels to Constance to a paragraph is 3:5 there are 280 letters in the paragraph how many are vowels how many are consonant
Answer:
280/8 = 35 "sets"
35*3 = 105 Constance
35*5 = 175 vowels
Step-by-step explanation:
There are 105 consonants and 175 vowels in a paragraph.
What is vowels and consonants?Vowels (such as a, e, I o, and u) and consonants combine to form words (the rest of the alphabet). The letter "y" is a little odd since it can function as a vowel or a consonant depending on the context. Spelling will be made easier for you if you understand how vowels and consonants combine to form words and sounds.
a speaking sound made by people when their teeth, tongue, or lips obstruct the breath from leaving their mouths. grammar. Except for the English vowels a, e, I o, and u, a consonant is a letter that represents a sound made in this way.
Given:
The ratio of vowels to Constance to a paragraph is 3:5 there are 280 letters in the paragraph.
First to find the number of sets in the paragraph as
[tex]\frac{280}{3+5} = \frac{280}{8} = 35[/tex]
Therefore, there are 35 sets in the paragraph.
So, 35 x 3 = 105 are consonants and
35 x 5 = 175 are vowels.

Find the measure of b.
A. 70
B. 110
C. 75
D. 100
Answer: C. 75
Concept:
Here, we need to know the idea of quadrilaterals in a circle.
The opposite angles of quadrilaterals in a circle (cyclic quadrilaterals) are supplementary, meaning they add up to 180°
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
Given information
The opposite angle of b = 105°
Given expression
b + opposite angle of b = 180°
Substitute values into the expression
b + 105 = 180
Subtract 105 on both sides
b + 105 - 105 = 180 - 105
b = 75°

7 is repeating
Answer:
[tex]\frac{17}{25}[/tex]
Step-by-step explanation:
So because it is a repeating decimal we have to round it off first. We can round it to the nearest hundredth making it 0.68. This then becomes [tex]\frac{68}{100}[/tex] as a fraction which can be reduced to its lowest terms by dividing both the numerator and denominator by 4 and then it becomes [tex]\frac{17}{25}[/tex].

A cylinder has a base area of 154 cm² and a height of 20cm. What is its total surface area, in cm?? Use, 22/7
This is answer A.1188
B.1200
C.1220
D.1224
Answer:
Hi there!
We've given with the base area and height. We know the formula for base area
Base area = πr²
154 = 22/7 × r²
154 × 7/22 = r²
49 = r²
√49 = r
7 = r
Now
TSA = 2πr(h + r)
TSA = 2 × 22/7 × 7(7 + 20)
TSA = 44(27)
TSA = 1188 cm²

Brainliest, please!
Step-by-step explanation:
68 + (5t - 8) = 180
5t + 60 = 180
5t = 120
t = 24
Answer:
24
Step-by-step explanation:
5t-8 and 68 are the angles of a straight line so their addition will be180°.
5t-8 + 68 = 180
5t + 60 = 180
5t = 180-60
5t = 120
t= 120/5
t= 24
