What is the measure of ∠P ?
with explanation pls

Answers

Answer 1

Answer:

80°

Step-by-step explanation:

we know angle R and angle Q are equal cause of the dashes

2x+30=6x-10

and then solve

30=4x-10

40=4x

10°=x

since they're equal just plug in X for one

2(10)+30= angle r

50° = angle r

we have two 50° angles and we know every triangle is 180°

so create the formula

angle r + angle q + angle p =180°

fill it in

50° + 50° + p = 180°

so angle p= 80°

A ladder 15 feet long leans against a house and makes an angle
of 60° with the ground. Find the distance from the house to the
foot of the ladder.
A 13 feet
)
B 7.5 feet
C 10 feet
D
8.2 feet

Answers

Answer:

Step-by-step explanation:

assume a right angle between the house and the ground.

then the ladder is the hypotenuse and distance from ladder to house is d

using the cosine ratio in the right triangle and the exact value

cos60° = [tex]\frac{1}{2}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{d}{15}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2x = 15 ( divide both sides by 2 )

x = 7.5

distance from house to foot of ladder is 7.5 feet

A bag contains green and black counters.
1
-
4
of the counters are black
Write the ratio of green to black counters.

Answers

Answer:

3:1

Step-by-step explanation:

if 1/4 of the counters are black then it means the total counters are 4 and so there are 3 remaining and those become the green counters

The ratio of green to black counters is 3:1

What is the Ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that A bag contains green and black counters, 1/4 of the counters are black.

Since, 1/4 is black counters therefore, 1 - 1/4 are green counters

So, there are 3/4 green counters

Ratio = (3/4)/(1/4) = 3/1 3:1

Hence, The ratio of green to black counters is 3:1

Step-by-step explanation:

3) line l and m are perpendicular so they intersect at 90 degrees

I labelled the angles that are the same measure.

2x + 23 = 90 subtract 23

2x = 67 divide by 2

x = 23.5 degrees

4) 2m + 66 = 120 subtract 66

2m = 54 divide by 2

m = 27 degrees

Tuesday he used 3/5 as many of 1/8

Answers

Answer:

19/40 = 0.475 You can use either the fraction or the decimal

Step-by-step explanation:

3/5 - 1/8 = 3 · 8/5 · 8 - 1 · 5/8 · 5 = 24/40 - 5/40 = 24 - 5/40 = 19/40

Answer:

[tex] \frac{3}{5} - \frac{1}{8} = \frac{19}{40} [/tex]

TOTAL:

=0.475

Step-by-step explanation:

3/5 - 1/8 = 3.8/5.8 - 1.5/8.5 = 24/40

- 5/40 = 24-5/40 - 24-6/40 =19/40

✿For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 8) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 8 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.
